In celebration of Hispanic Heritage Month, NASA is releasing new content for Universo curioso de la NASA, the agency’s first Spanish-language podcast, now in its second season. A five-week season starts Tuesday with new episodes released weekly.
Listen to the preview of the second season of Universo curioso de la NASA.
In each episode, Universo curioso highlights the contributions of NASA’s Hispanic and Latino workforce to the agency’s work in Earth and space exploration for the benefit of all.
“Through the Universo curioso de la NASA podcast, we are thrilled to tell the story of NASA’s efforts to open space to more people from across the world,” said Tonya McNair, deputy associate administrator for NASA’s Space Operations Mission Directorate in Washington. “In the second season, you’ll hear from NASA’s Hispanic and Latino workforce, like flight director Diana Trujillo and astronaut Marcos Berríos, helping lead some of the agency’s most vital space exploration missions and inspiring the world through discovery.”
Episodes focus on some of NASA’s top missions, bringing the wonder of exploration, space technology, and scientific discoveries to Spanish-speaking audiences around the world.
“This podcast highlights NASA’s dedication to making knowledge available to all, regardless of their native language,” said Shahra Lambert, NASA senior advisor for engagement. “By sharing the excitement of NASA’s missions in the second most spoken language in the U.S. and around the world, we are amplifying our outreach and possibly paving the way for a more diverse STEM workforce in the future.”
The first episode of Universo curioso ran in 2021, as part of the agency’s Spanish coverage of the launch of its James Webb Space Telescope. In 2023, the show was selected as a “Podcast We Love” by Apple Podcasts Latin America.
Hosted by Noelia González, communications specialist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, listeners are invited to go on a journey to one of Jupiter’s icy moons, hear about the first two years of discoveries of the James Webb Space Telescope, as well as learn about an astronaut from Puerto Rico’s and a Colombian flight director’s path to NASA.
Episodes will cover the upcoming launch of Europa Clipper in October 2024, a mission that aims to determine whether there are places below the surface of Jupiter’s icy moon, Europa, that could support life.
A complete list of the new episodes, as well as their release dates, is as follows:
- Tuesday, Sept. 17: Introducing the Second Season

Sols 4307-4308: Bright Rocks Catch Our Eyes NASA’s Mars rover Curiosity captured this image while exploring a rock-strewn channel of Gediz Vallis on the Red Planet. Mission scientists were particularly intrigued to investigate several bright-toned rocks (at the middle-right, bottom-right and bottom-center of the image), similar to rocks that Curiosity had encountered previously that were unexpectedly rich in sulfur. This image was taken by Left Navigation Camera aboard Curiosity on Sol 4306 — Martian day 4,306 of the Mars Science Laboratory Mission — on Sept. 16, 2024 at 12:47:18 UTC.NASA/JPL-CaltechEarth planning date: Monday, Sept. 16, 2024
We made good progress through Gediz Vallis in the weekend drive, landing in a segment of the channel containing a mix of loose rubble and other channel-filling debris. Amongst the jumbled scene, though, particular objects of interest caught our eye: bright rocks. In past workspaces in Gediz Vallis, similar bright rocks have been associated with very high to almost pure sulfur contents. As all good geologists know, however, color is not diagnostic, so we cannot assume these are the same as sulfur-rich rocks we have encountered previously. The only way to know is to collect data, and that was a significant focus of today’s plan.
We planned multiple mosaics across the examples of bright rocks visible in the image above. Mastcam and ChemCam RMI will cover “Bright Dot Lake” and “Sheep Creek” both in the right midfield of the image. Mastcam imaged the example in the bottom right corner of the image at “Marble Falls,” and ChemCam LIBS targeted one of the small bright fragments along the bottom of the image at “Blanc Lake.” There was also a small bit of bright material in the workspace, but unfortunately, it was not reachable by APXS. APXS analyzed a spot near the bright material, at target “Frog Lake,” and MAHLI was able to tack on a few extra images around that target that should capture the bright material. MAHLI also imaged a vuggy target in the workspace at “Grasshopper Flat.” The wider context of the channel was also of interest for imaging, so we captured the full expanse of the channel with one Mastcam mosaic, and focused another on mounds distributed through the channel at target “Copper Creek.”
Even with all this rock imaging, we did not miss a beat with our environmental monitoring. We planned regular RAD, REMS, and DAN measurements, mid and late day atmospheric dust observations, a cloud movie, and dust devil imaging.
Our drive is planned to take us up onto one of the ridges in the channel. Will we find more bright rocks there? Or something new and unexpected that was delivered down Gediz Vallis by some past Martian flood or debris flow? Only the channel knows!

Technicians Work to Prepare Europa Clipper for Propellant Loading
NASA’s Europa Clipper mission moves closer to launch as technicians worked on Wednesday, Sept. 11, inside the Payload Hazardous Servicing Facility to prepare the spacecraft for upcoming propellant loading at the agency’s Kennedy Space Center in Florida.
The spacecraft will explore Jupiter’s icy moon Europa, which is considered one of the most promising habitable environments in the solar system. The mission will research whether Europa’s subsurface ocean could hold the conditions necessary for life. Europa could have all the “ingredients” for life as we know it: water, organics, and chemical energy.
Europa Clipper’s launch period opens on Thursday, Oct. 10. It will lift off on a SpaceX Falcon Heavy rocket from Kennedy’s Launch Complex 39A. The spacecraft then will embark on a journey of nearly six years and 1.8 billion miles before reaching Jupiter’s orbit in 2030.
The spacecraft is designed to study Europa’s icy shell, underlying ocean, and potential plumes of water vapor using a gravity science experiment alongside a suite of nine instruments including cameras, spectrometers, a magnetometer, and ice-penetrating radar. The data Europa Clipper collects could improve our understanding of the potential for life elsewhere in the solar system.

Organized by the Science Mission Directorate’s Science Support Office (SSO), NASA hosted its 12th annual Earth Day Celebration event from April 18–19, 2024. For the first time ever, the two-day event was held at NASA Headquarters (HQ) in Washington, DC.
The in-person event, which was free and open to the public, featured the newly installed Earth Information Center (EIC) exhibit – see Photos 1–4. The event featured 17 hands-on activities offered in NASA HQ’s East Lobby as well as two adjacent outdoor tents. Event participants were given an activity passport called the “Passport to Fun” listing all the activities and encouraging attendees to visit the stations and interact with NASA staff – see Figure 1. After completing six or more activities, attendees were able to claim giveaway items, e.g., lenticulars, NASA bags, posters, and calendars.

Earth Day Activity Passport.Figure credit: NASAPrior to the event, Trena Ferrell [GSFC—Earth Science Education and Public Outreach Lead] arranged for groups of students from several local schools to visit the NASA Earth Day event. This included over 300 students from DuVal High School, Morgan State University, Howard University, Prince George’s County Environmental Academy, Prince George’s County Virtual Academy, International Hispanic School, and homeschoolers. On April 19, all of the students who were present at that time gathered for a plenary in the Webb Auditorium. Ferrell welcomed the attendees and provided introductions to prepare them for a virtual presentation by former NASA astronaut Paul Richards, who interacted with attendees and answered questions for roughly 20 minutes.
After Richard’s presentation, the attendees heard from Karen St. Germain [NASA HQ—Director of NASA’s Earth Science Division], whose in-person remarks emphasized to the students the crucial albeit less publicized studies that NASA does of our home planet. Related to this year’s Earth Day theme, “Water Touches Everything,” she discussed the ability of NASA’s Earth observing satellites to track water in all its forms as it circulates throughout the Earth system. St. Germain then answered questions from the audience for 15 minutes – see Photos 5–8.

While SSO staff distributed 500 activity passports, many small groups and families shared a single passport. SSO staff estimates that the true number of participants may be close to 1500 – see Photos 11–19.

NASA’s first Earth Day Celebration at NASA Headquarters was quite successful. While attendance was lower than previous events held at the more heavily trafficked Union Station or the National Mall, there was a steady stream of people throughout the exhibit on both days. It was also a great opportunity to showcase the new EIC to the public. Earth Day is the largest event organized annually by the SSO. This event requires months of planning, cross-divisional coordination, and intensive design of the hands-on activities – all carried from conceptualization through numerous revisions to implementation by more than 100 individuals from across the agency. This combined effort of SSO staff and assisting organizations results in an event that brings together thousands of visitors from a broad spectrum of ages and backgrounds to enjoy NASA science. This event would not have been possible were it not for the incredible efforts and collaboration put forth by so many of NASA’s outreach professionals. The SSO is grateful for all who helped to make this year’s Earth Day event a success and looks forward to Earth Day 2025.

NASA Completes Spacecraft to Transport, Support Roman Space Telescope
The spacecraft bus that will deliver NASA’s Nancy Grace Roman Space Telescope to its orbit and enable it to function once there is now complete after years of construction, installation, and testing.
Now that the spacecraft is assembled, engineers will begin working to integrate the observatory’s other major components, including the science instruments and the telescope itself.
“They call it a spacecraft bus for a reason — it gets the telescope to where it needs to be in space,” said Jackie Townsend, the Roman deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “But it’s really more like an RV because it has a whole assortment of functions that enable Roman to accomplish its scientific goals while out there too.”
Those goals include surveying wide swaths of the universe to study things like: dark energy, a mysterious cosmic pressure thought to accelerate the universe’s expansion; dark matter, invisible matter seen only via its gravitational influence; and exoplanets, worlds beyond our solar system.
The mission’s science wouldn’t be possible without a spacecraft to transport the telescope, point the observatory toward different cosmic targets, provide power, communicate with Earth, control and store instrument data, and regulate Roman’s temperature. Nearly 50 miles of electrical cabling are laced throughout the assembly to enable different parts of the observatory to communicate with each other.
The spacecraft will also deploy several major elements that will be stowed for launch, including the solar panels, deployable aperture cover, lower instrument Sun shade, and high-gain antenna. It’s also responsible for collecting and beaming down data, which is no small task for a space observatory that will survey the cosmos like Roman will.
“Roman will send back 1.4 terabytes of data per day, compared to about 50 to 60 gigabytes from the James Webb Space Telescope and three gigabytes from the Hubble Space Telescope,” said Jason Hylan, the Roman observatory manager at NASA Goddard. “Webb’s daily downlink is roughly comparable to 13 hours of YouTube video at the highest quality while Roman’s would amount to about 2 weeks.”
This top-down view shows NASA’s Nancy Grace Roman Space Telescope’s spacecraft bus from another angle. It rests atop an aluminum ring that will not be part of the observatory and is surrounded by an enclosure used in testing to ensure electromagnetic interference will not affect the bus’s sensitive electronics. The bus is covered in gray bagging material to prevent contamination –– even tiny stray particles could affect its performance.NASA/Chris Gunn A Goddard Grand SlamThis milestone is the culmination of eight years of spacecraft design work, building, and testing by hundreds of people at Goddard.
“Goddard employees were the brains, designers, and executors. And they worked with vendors who supplied all the right parts,” Townsend said. “We leaned on generations of expertise in the spacecraft arena to work around cost and schedule challenges that arose from supply chain issues and the pandemic.”
One time- and money-saving technique the team came up with was building a spacecraft mockup, called the structural verification unit. That allowed them to do two things at once: complete strength testing on the mockup, designed specifically for that purpose, while also assembling the actual spacecraft.
The spacecraft’s clever layout also allowed the team to adapt to changing schedules. It’s designed to be modular, “more like Trivial Pursuit pie pieces than a nesting egg, where interior components are buried inside,” Townsend said. “That’s been a game-changer because you can’t always count on things arriving in the order you planned or working perfectly right away with no tweaks.” It also increased efficiency because people could work on different portions of the bus at the same time without interfering with each other.
The slightly asymmetrical and hexagonal spacecraft bus is about 13 feet (4 meters) wide by 6.5 feet (2 meters) tall and weighs in at 8,400 pounds (3,800 kilograms).
While it may look small in this photo, the spacecraft bus for NASA’s Nancy Grace Roman Space Telescope is 13 feet (4 meters) wide by 6.5 feet (2 meters) tall and weighs in at 8,400 pounds (3,800 kilograms). In this photo, it rests atop an aluminum ring that will not be part of the observatory. The bundles of wires on top are part of more than 50 miles of cabling laced throughout the assembly to enable different parts of the observatory to communicate with each other.NASA/Chris GunnOne reason it doesn’t weigh more is that some components have been partially hollowed out. If you could peel back some of the spacecraft’s panels, you’d find superthin metallic honeycomb sandwiched between two slim layers of metal. And many of the components, such as the antenna dish, are made of strong yet lightweight composite materials.
When the spacecraft bus was fully assembled, engineers conducted a comprehensive performance test. Prior to this, each component had been tested individually, but just like with a sports team, the whole unit has to perform well together.
“The spacecraft passed the test, and now we’re getting ready to install the payload –– Roman’s instruments and the telescope itself,” said Missie Vess, a spacecraft systems engineer for Roman at NASA Goddard. “Next year, we’ll test these systems together and begin integrating the final components of the observatory, including the deployable aperture cover, outer barrel assembly, and solar panels. Then we’ll finally have ourselves a complete observatory, on track for launch by May 2027.”

The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems, Inc in Boulder, Colorado; L3Harris Technologies in Rochester, New York; and Teledyne Scientific & Imaging in Thousand Oaks, California.

“I would say family and part of that ‘first-gen experience’ [shaped me]. Being born in the U.S. gave me a lot of opportunities that my family and parents were robbed of because of situations in their home country. It shaped me to be a hard worker and to aspire to large things because not only was it my goal at this point, but it was also my parents’ aspiration.
“I feel that a lot of their pride comes from their kids. That pushes me to be a better employee or to want to do better for myself because I know that they’ve made a lot of sacrifices for me while I was building up to becoming an engineer. Now that I’ve accomplished my goal, it’s very important for me to always thank them and be a grateful person.
“Culture also shaped me. Coming from a minority background, and I’m only familiar with the Hispanic culture, it was an education-first mindset…and very supportive. I think that’s important. When I do outreach, I always like to share my experiences because sometimes, people don’t realize how much impact they can have, like the teacher who told me about [a NASA] internship. She didn’t know that was going to be my career. Or, my mom staying up with me during late night study sessions when I was like, ‘I can’t be an engineer’ and failed a test and she was like, ‘No, you can do it. I believe in you.’
“It might not be memorable for the person who [says it], but it was super important for my motivation to keep going. So, [online, I am that voice for] first-gen motivation.”

Reaching New Heights to Unravel Deep Martian History! This is an image of the rim that the Perseverance rover took on sol 383 (March 19th, 2022) when it was traversing the crater floor. Dox Castle is located at the top of the image in the far ground. NASA/JPL-Caltech/ASUThe Perseverance rover is reaching new heights as it ascends the rim of Jezero crater (over 300 meters in elevation higher than the original landing site)! The rover is now enroute to its first campaign science stop Dox Castle (image in the far ground) a region of interest for its potential to host ancient Mars’ bedrock in the exposed rocks on the rim.
Impact craters like Jezero may be the key to piecing together the early geologic history of Mars, as they provide a window into the history of the ancient crust by excavating and depositing deep crustal materials above the surface. Crater rims act as keepers of ancient Martian history, uplifting and exposing the stratigraphy of these impacted materials. Additionally, extreme heat from the impact can encourage the circulation of fluids through fractures similar to hydrothermal vents, which have implications for early habitability and may be preserved in the exposed rim bedrock. With the Perseverance rover we have the potential to explore some of the oldest exposed rocks on the planet.
Exploring such diverse terrains takes a lot of initial planning! The team has been preparing for the Crater Rim Campaign these last few months by working together to map out the types of materials Perseverance may encounter during its traverse up and through the rim. Using orbital images from the High-Resolution Imaging Science Experiment (HiRISE) instrument, the science team divided the rim area into 36 map quadrants, carefully mapping different rock units based on the morphologies, tones, and textures they observed in the orbital images. Mapping specialists then connected units across the quads to turn 36 miniature maps into one big geologic map of the crater rim. This resource is being used by the team to plan strategic routes to scientific areas of interest on the rim.
On Earth, geologic maps are made using a combination of orbital images and mapping in the field. Planetary scientists don’t typically get to check their map in the field, but we have the unique opportunity to validate our map using our very own robot geologist! Dox Castle will be our first chance to do rim science – and we’re excited to search for evidence of the transition between the margin and rim materials to start piecing together the stratigraphic history of the rocks that make up the rim of Jezero crater.

Station Science Top News: September 13, 2024
JAXA (Japan Aerospace Exploration Agency) researchers examined the structures of four titanium-based compounds solidified in levitators in microgravity and on the ground and found that the internal microstructures were generally similar. These results could support development of new materials for use in space manufacturing.
To produce glass or metal alloys on Earth, raw materials are placed into a container and heated. But reactions between the container and the materials can cause imperfections. The JAXA Electrostatic Levitation Furnace can levitate, melt, and solidify materials without a container. The facility enables measurement of the thermophysical properties of high temperature melts and could accelerate development of innovative materials such as heat resistant ceramics for use in the aerospace and energy industries.
JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide works with the Electrostatic Levitation Furnace.European Space Agency/Thomas PesquetSatellite 3D imaging of a Peruvian tropical forest demonstrated that measuring leaf traits with remote sensing may provide more accurate predictions of biomass production than structure data such as tree height. Carbon stored or sequestered in forests can help offset emissions that cause climate change, and improved estimates of tropical forest biomass could allow researchers to better evaluate these ecosystems and their offset contributions.
Global Ecosystem Dynamics Investigation (GEDI) provides high-resolution global observations of Earth’s forests and topography. These observations provide information on carbon and water cycling processes, biodiversity, and habitat, including quantifying carbon stored in vegetation and the potential for future carbon storage. The researchers suggest that estimates of tropical forest biomass could be further improved with data from new satellite missions and by integrating GEDI with dynamic vegetation models that include trait data.

The refrigerator-sized Global Ecosystem Dynamics Investigation instrument on the exterior of the International Space Station. NASA/Nick HagueResearch indicates that refractive eye surgery is safe, effective, and suitable for astronauts. The study documented stable vision in two astronauts who, a few years prior to flight, underwent photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK), respectively. These visual correction procedures can reduce the logistical complications of wearing glasses or contact lenses in space.
International Space Station Medical Monitoring collects health data from crew members before, during, and after spaceflight. The medical evaluation requirements, including vision assessment, apply to all crew members and are part of efforts by all international partners to maintain crew health, ensure mission success, and enable crew members to return to normal life on Earth after their missions.
NASA astronauts Terry Virts (bottom) and Scott Kelly (top) perform eye exams as part of ongoing studies into crew vision health. NASAJAXA researchers report that accurately assessing the velocity of airflow in front of a spreading flame makes it possible to predict the flammability of thin, flat materials in microgravity. These results mean it could be possible to use ground tests to predict the flammability of solid materials and thus ensure fire safety in spacecraft and space habitations.
The JAXA Fundamental Research on International Standard of Fire Safety in Space – Base for Safety of Future Manned Missions (FLARE) investigation tested the flammability of various solid materials in different configurations, including filter paper. Microgravity significantly affects combustion phenomena such as the spread of flame over solid materials; while flames cannot spread over solid materials under low-speed oxygen flow in Earth’s gravity, they can in microgravity due to the lack of buoyancy. Testing of the flammability of materials for spacecraft previously has not considered the effect of gravity, and results from this investigation could address this issue, significantly improving fire safety on future exploration missions.

Ottawa’s Fall Rhapsody
An astronaut aboard the International Space Station captured this view of peak fall foliage around Ottawa, Canada on Oct. 14, 2020. Sugar maple leaves turn orange-red, and hickories turn golden-bronze during autumn, regionally known as “the Fall Rhapsody.”
Fall color reaches its peak when air temperatures drop and shortened daylight triggers plants to slow and stop the production of chlorophyll—the molecule that plants use to synthesize food. When the green chlorophyll pigment fades, various yellow and red pigments become visible.

Going Back-to-School with NASA Data

Preparations for Next Moonwalk Simulations Underway (and Underwater)As students head back to school, teachers have a new tool that brings NASA satellite data down to their earthly classrooms.
The My NASA Data homepage categorizes content by areas of study called spheres and also Earth as a system. NASA/mynasadata.larc.nasa.govFor over 50 years of observing Earth, NASA’s satellites have collected petabytes of global science data (that’s millions and millions of gigabytes) – with terabytes more coming in by the day. Since 2004, the My NASA Data website has been developing ways for students and teachers of grades 3-12 to understand, and visualize NASA data, and to help incorporate those measurements into practical science lessons.
“We have three different types of lesson plans, some of which are student-facing and some are teacher-facing,” said Angie Rizzi, My NASA Data task lead, based at NASA’s Langley Research Center in Hampton, Virginia. “Teachers can download complete lesson plans or display a wide variety of Earth data. There are also lessons written for students to interact with directly.”
An image from My NASA Data’s Earth System Data Explorer visualization tool showing the monthly leaf index around the world as measured by NASA satellites in August 2020. Data parameters for this visualization were set to biosphere under the sphere dropdown and vegetation as a category. NASA/mynasadata.larc.nasa.govA key component of the My NASA Data site is the newly updated Earth System Data Explorer visualization tool, which allows users to access and download NASA Earth data. Educators can explore the data then create custom data tables, graphs, and plots to help students visualize the data. Students can create and investigate comparisons between land surface temperatures, cloud cover, extreme heat, and a wide range of other characteristics for a specific location or region around the globe.
An image from My NASA Data’s visualization tool showing various searchable categories under the atmosphere dataset selection. NASA/mynasadata.larc.nasa.gov“The Earth System Data Explorer tool has a collection of science datasets organized by different spheres of the Earth system,” explained Desiray Wilson, My NASA Data scientific programmer. The program highlights six areas of study: atmosphere, biosphere, cryosphere, geosphere, hydrosphere, and Earth as a system. “The data goes as far back as the 1980s, and we are getting more daily datasets. It’s really good for looking at historical trends, regional trends, and patterns.”
My NASA Data had over one million site visits last year, with some of the most popular searches focusing on temperatures, precipitation, water vapor, and air quality.
My NASA Data program leaders and instructors collaborating with educators from the North Carolina Space Grant at NASA’S Langley Research Center June 26, 2024. Teachers were at NASA Langley as part of the North Carolina Space Education Ambassadors (NCSEA) program and were given demonstrations of the My NASA Data website. NASA/David C. BowmanNatalie Macke has been teaching for 20 years and is a science teacher at Pascack Hills High School in Montvale, New Jersey. Teachers like Macke help shape the lessons on the site through internships with the My NASA Data team. Teachers’ suggestions were also incorporated to enhance the visualization tool by adding new features that now allow users to swipe between visual layers of data and make side-by-side comparisons. Users can also now click on a location to display latitude and longitude and variable data streamlining the previous site which required manual input of latitude and longitude.
“The new visualization tool is very much a point-and-click layout like our students are used to in terms of just quickly selecting data they want to see,” said Macke. “Instantaneously, a map of the Earth comes up, or just the outline, and they can get the satellite view. So if they’re looking for a specific city, they can find the city on the map and quickly grab a dataset or multiple datasets and overlay it on the map to make visual comparisons.”

This skill, she said, is invaluable, because it helps spread data literacy enabling users to look at data with a discriminating eye and learn to discern between assumptions and valid conclusions.
“Students can relate the data map to literally what’s happening outside their window, showing them how NASA Earth system satellite data relates to real life,” said Macke. “Creating a data literate public – meaning they understand the context and framework of the data they are working with and realizing the connection between the data and the real world – hopefully will intrigue them to continue to explore and learn about the Earth and start asking questions. That’s what got me into science when I was a little kid.”

Aura at 20 YearsIntroduction
In the 1990s and early 2000s, an international team of engineers and scientists designed an integrated observatory for atmospheric composition – a bold endeavor to provide unprecedented detail that was essential to understanding how Earth’s ozone (O3) layer and air quality respond to changes in atmospheric composition caused by human activities and natural phenomena. This work addressed a key NASA Earth science objective. Originally referred to as Earth Observing System (EOS)–CHEM (later renamed Aura,) the mission would become the third EOS Flagship mission, joining EOS-AM 1 (Terra) launched in 1999 and EOS-PM 1 (Aqua), launched in 2002. The Aura spacecraft – see Figure 1 – is similar in design to Terra and identical to Aqua. Aura and its four instruments were launched on July 15, 2004 from Vandenberg Air Force Base (now Space Force Base) in California – see Photo.

Image credit: NASAIn 2014 The Earth Observer published an article called “Aura Celebrates Ten Years in Orbit,” [Nov–Dec 2014, 26:6, pp. 4–18] which details the history of Aura and the first decade of science resulting from its data. Therefore, the current article will focus on the science and applications enabled by Aura data in the last decade. It also examines Aura’s future and the legacies of the spacecraft’s instruments.

Recent Science Achievements from Aura’s Instrument (in alphabetical order)
High Resolution Dynamics Limb Sounder
The capabilities of the High Resolution Dynamics Limb Sounder (HIRDLS) were compromised at launch and operations ceased in March 2008 due to an image chopper stall. Nevertheless, the HIRDLS team was able to produce a three-year dataset notable for high vertical resolution profiles of greater than 1 km (0.62 mi) for temperature and O3 in the upper troposphere to the mesosphere. Though limited, the HIRDLS dataset demonstrated the incredible potential of the instrument for atmospheric research. So much so, that scientists are now in the study phase for a new instrument, part of the proposed Stratosphere Troposphere Response using Infrared Vertically-Resolved Light Explorer (STRIVE) mission, which would have similar capabilities as HIRDLS with advancements in spectral and spatial imaging. (STRIVE is one of four missions currently undergoing one-year concept studies, as part of NASA’s Earth System Explorer Program, which was established in the 2017 Earth Science Decadal Survey. Two winning proposals will be chosen in 2025 for full development and launch in 2030 or 2032.)
Microwave Limb Sounder
The Microwave Limb Sounder (MLS) was developed to study: 1) the evolution and recovery of the stratospheric O3 layer; 2) the role of the stratosphere, notably stratospheric humidity, in climate feedback processes; and 3) the behavior of air pollutants in the upper troposphere. MLS measures vertical profiles from the upper troposphere at ~10 km altitude (6.2 mi) to the mesosphere at ~90 km (56 mi) of 16 trace gases, temperature, geopotential height, and cloud ice. Its unique measurement suite has made it the “go-to” instrument for most data-driven studies of middle atmosphere composition over the last two decades.
Data collection during the past decade has highlighted the ability of the stratosphere to exhibit surprising and/or envelope-redefining behavior, (Envelope-redefining is a term that is used to refer to an event that greatly exceeded previous observed ranges of this event.) MLS observations have been crucial for the discovery and diagnoses of these extreme events. For example, in 2019, a stratospheric sudden warming over the southern polar cap in September – rare in the Antarctic – curtailed chemical processing, leading to an anomalously weak O3 hole. As another example, prolonged hot and dry conditions in Australia during the subsequent 2019–2020 southern summer promoted the catastrophic “Australian New Year” (ANY) fires. MLS observations showed that fire-driven pyrocumulonimbus convection lofted plumes of polluted air into the stratosphere to a degree never seen during the Aura mission.
Apart from those individual plumes, smoke pervaded the southern lower stratosphere, leading to unprecedented perturbations in southern midlatitude lower stratospheric composition, with chlorine (Cl) shifting from its main reservoir species, hydrochloric acid (HCl), into the O3-destroying form, hypochlorite (ClO). Peak anomalies in chlorine species occurred in mid-2020 – months after the fires. State-of-the-art atmospheric chemistry models in which wildfire smoke has properties similar to those of sulfate (SO4) aerosols were unable to reproduce the observed chemical redistribution. New model simulations assuming that HCl dissolves more readily in smoke than in SO4 particles under typical midlatitude stratospheric conditions better match the MLS observations.
As extraordinary as these events were, their impacts on the stratosphere were spectacularly eclipsed by the impact of the January 2022 eruption of the Hunga Tonga-Hunga Ha’apai (Hunga) volcano in the Pacific Ocean. The Hunga eruption lofted about 150 Tg of water vapor into the stratosphere – with initial injections reaching into the mesosphere. The eruption almost instantaneously increased total stratospheric water vapor by about 10%. MLS was the only sensor able to track the plume in the first weeks following the eruption. The Hunga humidity enhancement resulted in an envelope-redefining, low-temperature anomaly in the stratosphere, in turn inducing changes in stratospheric circulation. Repartitioning of southern midlatitude Cl also occurred, though to a lesser degree than following the ANY fires and in a manner broadly consistent with known chemical mechanisms. The Hunga water vapor enhancement has not substantially declined in the 2.5 years since the eruption, and studies indicate that it will likely endure for several more years.
Impacts of the Hunga humidity on polar O3 loss have also been investigated. The timing and location of the eruption were such that the plume reached high southern latitudes only after the 2022 Antarctic winter vortex had developed. Since the strong winds at the vortex edge present a transport barrier, polar stratospheric cloud (PSC) formation and O3 hole evolution were largely unaffected. When the vortex broke down at the end of the 2022 Antarctic winter, moist air flooded the southern polar region, increasing humidity in the region. Cold, moist conditions led to unusually early and vertically extensive PSC formation and Cl activation, but chemical processing ran to completion by mid-July, as typically occurs in southern winter. The cumulative chemical O3 losses ended up being unremarkable throughout the lower stratosphere. The Hunga plume was also largely excluded from the 2022–2023 Arctic vortex. The 2023–2024 Arctic O3 loss season was characterized by conditions that were dynamically disturbed and not persistently cold, and springtime O3 was near or above average. The extraordinary stratospheric hydration from Hunga has so far had minimal impact on chemical processing and O3 loss in the polar vortices in either hemisphere – see Figure 2.
Figure 2. The evolution of MLS water vapor anomalies (deviations from the baseline 2005–2021 climatology) from January 2019 through December 2023 as a function of equivalent latitude at 700 K potential temperature in the middle stratosphere at ~27 km altitude (17 mi). Black contours mark the approximate edge of the polar vortex. The green triangle marks the time of the main Hunga eruption at latitude 20.54°S on January 15, 2022. Figure credit: Updated and adapted from a 2023 paper in Geophysical Research LettersWith the end of Aura and MLS, the future for stratospheric limb sounding observations is unclear. While stratospheric O3 and aerosol will continue to be measured on a daily, near-global basis by the Ozone Mapping and Profiler Suite (OMPS) Limb Profiler (OMPS-LP) instruments on the Suomi National Polar-orbiting Partnership (Suomi NPP) and Joint Polar Satellite System (JPSS-2, -3, and -4) satellites, there are no confirmed plans for daily, near-global observations of either long-lived trace gases or halogenated species – both of which are needed to diagnose observed changes in O3. The only other sensor making such measurements, the Canadian Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE–FTS), is itself older than MLS and, as a solar occultation instrument, measures only 30 profiles-per-day, taking around a month to cover all latitudes. Similarly, no other sensor is set to provide daily, near-global measurements of stratospheric water vapor until the launch of the Canadian High-altitude Aerosols, Water vapour and Clouds (HAWC) mission in the early 2030s. Some potential new mission concepts are under consideration by both NASA and ESA, but they are subject to competition. Even if both instruments are ultimately selected, gaps in the records of many species measured by MLS are inevitable. The MLS PI is leading an effort to develop new technologies that would allow an instrument that could restart MLS measurements to be built in a far smaller mass/power footprint (e.g., 60 kg, 90 W vs. 500 kg, 500 W for Aura MLS), and technologies exist for yet-smaller MLS-like instruments that could assume the legacy of the highly impactful MLS record at low cost in future decades.
Ozone Monitoring Instrument
The Ozone Monitoring Instrument (OMI) continues the Total Ozone Mapping Spectrometer (TOMS) record for total O3 and other atmospheric parameters related to O3 chemistry and climate. It employs hyperspectral imaging in a push-broom mode to observe solar backscatter radiation in the visible and ultraviolet.
OMI is a Dutch–Finnish contribution to the Aura mission, and its remarkable stability and revolutionary two-dimensional (2D) detector (spatial in one dimension and spectral in the other) has produced a two-decade record of science- and trend-quality datasets of atmospheric column observations. OMI continues the long-term record of total column O3 measurements begun in 1979, and its observations of nitrogen dioxide (NO2), sulfur dioxide (SO2), formaldehyde (CH2O), and absorbing aerosols provided exceptional spatial resolution for study of anthropogenic and natural trends and variations of these pollutants around the world. Its radiometric and spectral stability has made it a valuable contributor for solar spectral irradiance measurements to complement dedicated solar instruments on other satellites. The many achievements made possible with OMI are documented in a review article.
OMI’s multidecade data records have revolutionized the ability to monitor air quality changes around the world, even at the sub-urban level. In particular, OMI NO2 data have been transformative. Recently, these data were used to track changes in air pollution associated with efforts to control the spread of SARS-CoV-2. OMI’s long, stable data record allowed for changes in pollution levels in 2020 – at the height of global lockdowns – to be put into historical perspective, especially within the envelope of typical year-to-year variations associated with meteorological variability. Many research studies assessed the impact of the pandemic lockdowns on air pollution, supporting novel uses of OMI data for socioeconomic-related research. For example, OMI NO2 data were shown to serve as an environmental indicator to evaluate the effectiveness of lockdown measures and as a significant predictor for the deceleration of COVID-19 spread. OMI NO2 data were also used as a proxy for the economic impact of the pandemic as NO2 is emitted during fossil fuel combustion, which is another proxy for economic activity since most global economies are driven by fossil fuels – see Animation.

OMI’s datasets are being continued by successor 2D detector array instruments, such as the previously mentioned Copernicus Sentinel-5P TROPOMI mission, the Republic of Korea’s Geostationary Environment Monitoring Spectrometer (GEMS), and NASA’s Tropospheric Emissions: Monitoring of Pollution (TEMPO). All of these missions have enhanced spatial resolution relative to OMI, but have benefited from the innovative retrieval algorithms pioneered by OMI’s retrieval teams.
Tropospheric Emission Spectrometer
The Tropospheric Emission Spectrometer (TES) provided vertically-resolved distributions of a number of tropospheric constituents, e.g., O3, methane (CH4), and various volatile organic compounds. The instrument was decommissioned in 2018 due to signs of aging associated with a failing Interferometer Control System motor encoder bearing. Nevertheless, TES measurements led to a number of key results regarding changes in atmospheric composition that were published over the past 10 years.
Measurements from TES, OMI, and MLS showed that transport of O3 and its precursors from East Asia offset about 43% of the decline expected in O3 over the western U.S., based on emission reductions observed there over the period 2005–2010. TES megacity measurements revealed that the frequency of high-O3 days is particularly pronounced in South Asian megacities, which typically lack ground-based pollution monitoring networks. TES water vapor and semi-heavy water measurements indicated that water transpired from Amazonian vegetation becomes a significant moisture source for the atmosphere, during the transition from dry to wet season. The increasing water vapor provides the fuel needed to start the next rainy season. Measurements of CH4 from TES and carbon monoxide (CO) from Measurements of Pollution in the Troposphere (MOPITT) on Terra showed that CH4 emissions from fires declined at twice the rate expected from changes in burned area from 2004–2014. This finding helped to balance the CH4 budget for this period, because it offset some of the large increases in fossil fuel and wetland emissions. Through direct measurement of the O3 greenhouse gas effect, TES instantaneous radiative kernels revealed the impact of hydrological controls on the O3 radiative forcing and were used to show substantial radiative bias in Intergovernmental Panel on Climate Change (IPCC) chemistry–climate models. The TES team pioneered the retrieval of a number of species, such as peroxyacetyl nitrate, carbonyl sulfide, and ethylene.
The spirit of TES lives on through the NASA TRopospheric Ozone and its Precursors from Earth System Sounding (TROPESS) project, which generates data products of O3 and other atmospheric constituents by processing data from multiple satellites through a common retrieval algorithm and ground data system. TROPESS builds upon the success of TES and is considered a bridge to allow the development of a continuous record of O3 and other trace gas species as a follow-on to TES.
Future of Aura
In April 2023, Aura’s mission operations team performed the last series of maneuvers to maintain its position in the A-Train constellation of satellites. Since then, Aura has begun drifting. As of July 2024, Aura has descended ~5 km (3 mi) in altitude from ~700 km (435 mi) and its equator crossing time has increased by ~9 min from ~1:44 PM local time. This amount of drift is small, and the Aura MLS and OMI retrieval teams are ensuring the science- and trend-quality of the datasets.
As Aura continues to drift, the amount of sunlight reaching its solar panels will slowly decrease and will no longer be able to generate sufficient power to operate the spacecraft and instruments by mid-2026. At this point, the amount of local time drift will still be relatively small – less than one hour – so the retrieval teams will be able to ensure quality for most data products until this time.
In the remaining years, Aura’s aging but remarkably stable instruments will continue to add to the unprecedented two decades of science- and trend-quality data of numerous key tropospheric and stratospheric constituents. Aura data will be key for monitoring the evolution of the Hunga volcanic plume and understanding its continued impact on the chemistry and dynamics of the stratosphere. Observations from MLS and OMI will also be used to evaluate data from new and upcoming instruments (e.g., ESA’s Atmospheric Limb Tracker for Investigation of Upcoming Stratosphere (Altius); NASA’s TEMPO, Plankton, Aerosol, Cloud, ocean Ecosystem (PACE), and Total and Spectral Solar Irradiance Sensor-2 (TSIS-2) missions, or at least used to help minimize the gaps between data collections.
Aura’s Scientific Legacy
The Aura mission has been nothing short of transformative for atmospheric research and applied sciences. The multidecade, stable datasets have furthered process-based understanding of the chemistry and dynamics of atmospheric trace gases, especially those critical for understanding the causes of trends and variations in Earth’s protective ozone layer.
The two decades that Aura has flown have been marked by profound atmospheric changes and numerous serendipitous events, both natural and man-made. The data from Aura’s instruments have given scientists and applied scientists an unparalleled view – including at the sub-urban scale – of air pollution around the world, clearly showing the influence of rapid industrialization, environmental regulations designed to improve air quality, seasonal agricultural burning, catastrophic wildfires, and even a global pandemic, on the air we breathe. The Aura observational record spans the period that includes the decline of O3-destroying substances, and Aura data illustrate the beginnings of the recovery of the Antarctic O3 hole, a result of unparalleled international cooperation to reduce these substances.
Aura’s datasets have given a generation of scientists the most comprehensive global view to date of critical gases in Earth’s atmosphere and the chemical and dynamic processes that shape their concentrations. Many, but not all, of these datasets are being/will be continued by successor instruments that have benefited from the novel technologies incorporated into the design of Aura’s instruments as well as the innovative retrieval algorithms pioneered by Aura’s retrieval teams.
Acknowledgements
The author wishes to acknowledge the decades of hard work of the many hundreds of people who have contributed to the success of the international Aura mission. There are too many to acknowledge here and I’m sure that many names from the early days are lost to time. I would like to offer special thanks to those scientists who, back in the 1980s, first dreamed of the mission that would become Aura.

55 Years Ago: Space Task Group Proposes Post-Apollo Plan to President Nixon
The Apollo 11 mission in July 1969 completed the goal set by President John F. Kennedy in 1961 to land a man on the Moon and return him safely to the Earth before the end of the decade. At the time, NASA planned nine more Apollo Moon landing missions of increasing complexity and an Earth orbiting experimental space station. No firm human space flight plans existed once these missions ended in the mid-1970s. After taking office in 1969, President Richard M. Nixon chartered a Space Task Group (STG) to formulate plans for the nation’s space program for the coming decades. The STG’s proposals proved overly ambitious and costly to the fiscally conservative President who chose to take no action on them.

Right: President Lyndon B. Johnson addresses a crowd during a March 1968 visit to the Manned Spacecraft Center, now NASA’s Johnson Space Center, in Houston.
On May 25, 1961, before a Joint Session of Congress, President John F. Kennedy committed the United States to the goal, before the decade was out, of landing a man on the Moon and returning him safely to the Earth. President Kennedy reaffirmed the commitment during an address at Rice University in Houston in September 1962. Vice President Lyndon B. Johnson, who played a leading role in establishing NASA in 1958, under Kennedy served as the Chair of the National Aeronautics and Space Council. Johnson worked with his colleagues in Congress to ensure adequate funding for the next several years to provide NASA with the needed resources to meet that goal.
Following Kennedy’s assassination in November 1963, now President Johnson continued his strong support to ensure that his predecessor’s goal of a Moon landing could be achieved by the stipulated deadline. But with increasing competition for scarce federal resources from the conflict in southeast Asia and from domestic programs, Johnson showed less interest in any space endeavors to follow the Apollo Moon landings. NASA’s annual budget peaked in 1966 and began a steady decline three years before the agency met Kennedy’s goal. From a budgetary standpoint, the prospects of a vibrant, post-Apollo space program didn’t look all that rosy, the triumphs of the Apollo missions of 1968 and 1969 notwithstanding.

Right: An illustration of the Apollo Applications Program experimental space station that later evolved into Skylab.
Less than a month after assuming the Presidency in January 1969, Richard M. Nixon appointed a Space Task Group (STG), led by Vice President Spiro T. Agnew as the Chair of the National Aeronautics and Space Council, to report back to him on options for the American space program in the post-Apollo years. Members of the STG included NASA Acting Administrator Thomas O. Paine (confirmed by the Senate as administrator on March 20), the Secretary of Defense, and the Director of the Office of Science and Technology. At the time, the only approved human space flight programs included lunar landing missions through Apollo 20 and three long-duration missions to an experimental space station based on Apollo technology that evolved into Skylab.
Beyond a general vague consensus that the United States human space flight program should continue, no approved projects existed once these missions ended by about 1975. With NASA’s intense focus on achieving the Moon landing within President Kennedy’s time frame, long-term planning for what might follow the Apollo Program garnered little attention. During a Jan. 27, 1969, meeting at NASA chaired by Acting Administrator Paine, a general consensus emerged that the next step after the Moon landing should involve the development of a 12-person earth-orbiting space station by 1975, followed by an even larger outpost capable of housing up to 100 people “with a multiplicity of capabilities.” In June, with the goal of the Moon landing almost at hand, NASA’s internal planning added the development of a space shuttle by 1977 to support the space station, the development of a lunar base by 1976, and the highly ambitious idea that the U.S. should prepare for a human mission to Mars as early as the 1980s. NASA presented these proposals to the STG for consideration in early July in a report titled “America’s Next Decades in Space.”

Still bathing in the afterglow of the successful Moon landing, the STG presented its 29-page report “The Post-Apollo Space Program: Directions for the Future” to President Nixon on Sep. 15, 1969, during a meeting at the White House. In its Conclusions and Recommendations section, the report noted that the United States should pursue a balanced robotic and human space program but emphasized the importance of the latter, with a long-term goal of a human mission to Mars before the end of the 20th century. The report proposed that NASA develop new systems and technologies that emphasized commonality, reusability, and economy in its future programs. To accomplish these overall objectives, the report presented three options:
Option I – this option required more than a doubling of NASA’s budget by 1980 to enable a human Mars mission in the 1980s, establishment of a lunar orbiting space station, a 50-person Earth orbiting space station, and a lunar base. The option required a decision by 1971 on development of an Earth-to-orbit transportation system to support the space station. The option maintained a strong robotic scientific and exploration program.
Option II – this option maintained NASA’s budget at then current levels for a few years, then anticipated a gradual increase to support the parallel development of both an earth orbiting space station and an Earth-to-orbit transportation system, but deferred a Mars mission to about 1986. The option maintained a strong robotic scientific and exploration program, but smaller than in Option I.
Option III – essentially the same as Option II but deferred indefinitely the human Mars mission.
In separate letters, both Agnew and Paine recommended to President Nixon to choose Option II.

The White House released the report to the public at a press conference on Sep. 17 with Vice President Agnew and Administrator Paine in attendance. Although he publicly supported a strong human spaceflight program, enjoyed the positive press he received when photographed with Apollo astronauts, and initially sounded positive about the STG options, President Nixon ultimately chose not to act on the report’s recommendations. Nixon considered these plans too grandiose and far too expensive and relegated NASA to one America’s domestic programs without the special status it enjoyed during the 1960s. Even some of the already planned remaining Moon landing missions fell victim to the budgetary axe.
On Jan. 4, 1970, NASA had to cancel Apollo 20 since the Skylab program needed its Saturn V rocket to launch the orbital workshop. In 1968, then NASA Administrator James E. Webb had turned off the Saturn V assembly line and none remained beyond the original 15 built under contract. In September 1970, reductions in NASA’s budget forced the cancellation of two more Apollo missions, and in 1971 President Nixon considered cancelling two more. He reversed himself and they flew as Apollo 16 and Apollo 17 in 1972, the final Apollo Moon landing missions.

More than two years after the STG submitted its report, in January 1972 President Nixon directed NASA Administrator James C. Fletcher to develop the Space Transportation System, the formal name for the space shuttle, the only element of the recommendations to survive the budgetary challenges. NASA anticipated the first orbital flight of the program in 1979, with the actual first flight occurring two years later. Twelve years elapsed after Nixon’s shuttle decision when President Ronald W. Reagan approved the development of a space station, the second major component of the STG recommendation. 14 years later, the first element of that program reached orbit. In those intervening years, NASA had redesigned the original American space station, leading to the development of a multinational orbiting laboratory called the International Space Station. Humans have inhabited the space station continuously for the past quarter century, conducting world class and cutting edge scientific and engineering research. Work on the space station helps enable future programs, returning humans to the Moon and later sending them on to Mars and other destinations.

NASA Johnson Honors Hispanic Heritage: Meet Manuel Retana
Manuel Retana arrived in the U.S. at 15 years old, unable to speak English and with nothing but a dream and $200 in his pocket. Now, he plays a crucial role implementing life support systems on spacecraft that will carry humans to the Moon and, eventually, Mars—paving the way for the next frontier of space exploration.
A project manager for NASA’s Johnson Space Center Life Support Systems Branch in Houston, Retana helps to ensure astronaut safety aboard the International Space Station and for future Artemis missions. His work involves tracking on-orbit technical issues, managing the cost and schedule impacts of flight projects, and delivering emergency hardware.
Manuel Retana stands in front of NASA’s Space Launch System rocket at Kennedy Space Center in Florida.One of his most notable achievements came during the qualification of the Orion Smoke Eater Filter for the Artemis II and III missions. The filter is designed to remove harmful gases and particulates from the crew cabin in the event of a fire inside the spacecraft. Retana was tasked with creating a cost-effective test rig – a critical step for making the filter safe for flight.
Retana’s philosophy is simple: “Rockets do not build themselves. People build rockets, and your ability to work with people will define how well your rocket is built.”
Throughout his career, Retana has honed his soft skills—communication, leadership, collaboration, and conflict resolution—to foster an environment of success.
Retana encourages his colleagues to learn new languages and share their unique perspectives. He even founded NASA’s first Mariachi ensemble, allowing him to share his cultural heritage in the workplace.
He believes diversity of thought is a key element in solving complex challenges as well as creating an environment where everyone feels comfortable sharing their perspectives.
“You need to be humble and have a willingness to always be learning,” he said. “What makes a strong team is the fact that not everyone thinks the same way.”
Manuel Retana, center, performs with the Mariachi Ensemble group at NASA’s Johnson Space Center in Houston.For the future of space exploration, Retana is excited about the democratization of space, envisioning a world where every country has the opportunity to explore. He is eager to see humanity reach the Moon, Mars, and beyond, driven by the quest to answer the universe’s most enigmatic questions.
To the Artemis Generation, he says, “Never lose hope, and it is never too late to start following your dreams, no matter how far you are.”

Sols 4304-4006: 12 Years, 42 Drill Holes, and Now… 1 Million ChemCam Shots! In celebration of ChemCam’s milestone, here is a stunning image from its remote micro imager, showing details in the landscape far away. This image was taken by Chemistry & Camera (ChemCam) onboard NASA’s Mars rover Curiosity on Sol 4302 — Martian day 4,302 of the Mars Science Laboratory mission — on Sept. 12, 2024, at 09:20:51 UTC. NASA/JPL-CaltechEarth planning date: Friday, Sept. 13, 2024
Today, I need to talk about ChemCam, our laser and imaging instrument on the top of Curiosity’s mast. It one of the instruments in the “head” that gives Curiosity that cute look as if it were looking around tilting its head down to the rocks at the rover’s wheels. On Monday, 19th August the ChemCam team at CNES in France planned the 1 millionth shot and Curiosity executed it on the target Royce Lake on sol 4281 on Mars. Even as an Earth scientist used to really big numbers, this is a huge number that took me a while to fully comprehend. 1 000 000 shots! Congratulations, ChemCam, our champion for getting chemistry from a distance – and high-resolution images, too. If you are now curious how Curiosity’s ChemCam instrument works, here is the NASA fact sheet. And, of course, the team is celebrating, which is expressed by those two press releases, one from CNES in France and one from Los Alamos National Laboratory, the two institutions who collaborated to develop and build ChemCam and are now running the instrument for over 12 years! And the PI, Dr Nina Lanza from Los Alamos informs me that the first milestone – 10000 shots was reached as early as Sol 42, which was the sol the DAN instrument used its active mode for the first time. But before I am getting melancholic, let’s talk about today’s plan!
The drive ended fairly high up in the terrain, and that means we see a lot of the interesting features in the channel and generally around us. So, we are on a spot a human hiker would probably put the backpack down, take the water bottle out and sit down with a snack to enjoy the view from a nice high point in the landscape. Well, no such pleasures for Curiosity – and I am pretty sure sugar, which we humans love so much, wouldn’t be appreciated by rover gears anyway. So, let’s just take in the views! And that keeps Mastcam busy taking full advantage of our current vantage point. We have a terrain with lots of variety in front of us, blocks, boulders, flatter areas and the walls are layered, beautiful geology. Overall there are 11 Mastcam observations in the plan adding up to just about 100 individual frames, not counting those taken in the context of atmospheric observations, which are of course also in the plan. The biggest mosaics are on the targets “Western Deposit,” “Balloon Dome,” and “Coral Meadow.” Some smaller documentation images are on the targets “Wales Lake,” “Gnat Meadow,” and “Pig Chute.”
ChemCam didn’t have long to dwell on its milestone, as it’s busy again today. Of course, it will join Mastcam in taking advantage of our vantage point, taking three remote micro imager images on the landscape around us. LIBS chemistry investigations are targeting “Wales Lake,” “Gnat Meadow,” and “Pig Chute.” APXS is investigating two targets, “College Rock” and “Wales Lake,” which will also come with MAHLI documentation. With all those investigations together, we’ll be able to document the chemistry of many targets around us. There is such a rich variety of dark and light toned rocks, and with so much variety everywhere, it’s hard to choose and the team is excited about the three targeted sols … and planning over 4 hours of science over the weekend!
The next drive is planned to go to an area where there is a step in the landscape. Geologists love those steps as they give insights into the layers below the immediate surface. If you have read the word ‘outcrop’ here, then that’s what that means: access to below the surface. But there are also other interesting features in the area, hence we will certainly have an interesting workspace to look at! But getting there will not be easy as the terrain is very complex, so we cannot do it in just one drive. I think there is a rule of thumb here: the more excited the geo-team gets, the more skills our drivers need. Geologists just love rocks, but of course, no one likes driving offroad in a really rocky terrain – no roads on Mars. And right now, our excellent engineers have an extra complication to think about: they need to take extra care where and how to park so Curiosity can actually communicate with Earth. Why? Well, we are in a canyon, and those of you liking to hike, know what canyons mean for cell phone signals… yes, there isn’t much coverage, and that’s the same for Curiosity’s antenna. This new NASA video has more information and insights into the planning room, too! So, we’ll drive halfway to where we want to be but I am sure there will be interesting targets in the new workspace, the area is just so, so complex, fascinating and rich!
And that’s after Mars for you, after 12 years, 42 drill holes, and now 1 Million ChemCam shots. Go Curiosity go!!!
