How can future lunar exploration communicate from the far side of the Moon despite never being inline with the Earth? This is what a recent study submitted to IEEE Transactions on Aerospace and Electronic Systems hopes to address as a pair of researchers from the Polytechnique Montréal investigated the potential for a wireless power transmission method (WPT) comprised of anywhere from one to three satellites located at Earth-Moon Lagrange Point 2 (EMLP-2) and a solar-powered receiver on the far side of the Moon. This study holds the potential to help scientists and future lunar astronauts maintain constant communication between the Earth and Moon since the lunar far side of the Moon is always facing away from Earth from the Moon’s rotation being almost entirely synced with its orbit around the Earth.

Here, Universe Today discusses this research with Dr. Gunes Karabulut Kurt, who is an associate professor at IEEE Polytechnique Montréal and the study’s co-author, regarding the motivation behind the study, significant results, follow-up research, and implications for WPT. So, what was the motivation behind this study?

“This research is motivated by the objective of overcoming the logistical and technical challenges associated with using traditional cables on the Moon’s surface,” Dr. Kurt tells Universe Today. “Laying cables on the Moon’s rough, dusty surface would lead to ongoing maintenance and wear problems, as lunar dust is highly abrasive. On the other hand, transporting large quantities of cables to the Moon requires a significant amount of fuel, which adds considerably to the mission’s costs.”

For the study, the researchers used a myriad of calculations and computer models to ascertain if one, two, or three satellites are sufficient within an EMLP-2 halo orbit to maintain both constant coverage of the lunar far side (LFS) and line of sight with the Earth. For context, EMLP-2 is located on the far side of the Moon with the halo orbit being perpendicular—or sideways—to the Moon’s orbit. The calculations involved in the study included the distances between each satellite, the antenna angles between the satellites and surface receiver, the amount of LFS surface coverage, and the amount of transmitted power between the satellites and LFS surface antennae. So, what were the most significant results from this study?

Dr. Kurt tells Universe Today their models concluded that three satellites in an EMLP-2 halo orbit and operating at equal distances from each other could “achieve continuous power beaming to a receiver optical antenna anywhere on the lunar far side” while maintaining 100 percent LFS coverage and line of sight with the Earth. “Aside triple satellite scheme that provides continuous LFS full coverage, even a two-satellite configuration provides full coverage during 88.60% of a full cycle around the EMLP-2 halo orbit,” Dr. Kurt adds.

Regarding follow-up research, Dr. Kurt tells Universe Today, “Our future studies will focus on more complex harvesting and transmission models to get closer to reality. On the other hand, an approach that takes into account the irregular nature of lunar dust and the variation in its density due to environmental factors such as subsolar angle and others. In the future, if research in this field continues, explore this experimentally with lunar dust simulants and lasers.”

This study comes as NASA is preparing to send astronauts to the Moon for the first time since 1972 with the Artemis program, whose goal will be to land the first woman and person of color on the lunar surface. With the success of the Artemis 1 mission in November 2022 that consisted of an uncrewed Orion capsule orbiting the Moon, NASA is currently targeting September 2025 for their Artemis 2 mission, which is scheduled to be a 10-day, 4-person crewed mission using the Orion capsule for a lunar flyby, whose goal will be to conduct a full systems checkout of the Orion capsule. Therefore, what implications can this study have for the upcoming Artemis missions, or any future human exploration of the Moon?

“The findings have implications for the design of energy transmission systems on the Moon,” Dr. Kurt tells Universe Today. “A better understanding of the wireless transmission disruptors such as lunar dust can lead to the development of more efficient and reliable systems for powering lunar missions and infrastructure, including those related to the Artemis program and future human exploration efforts.”

If successful, Artemis 2 will be followed by Artemis 3 in September 2026, which will also consist of a 4-person crew with two crew members landing on the lunar surface and an approximate mission duration of 30 days. This will be followed by Artemis 4, Artemis 5, and Artemis 6, which are currently scheduled for September 2028, September 2029, and September 2030, respectively, with each mission increasing in both the number of astronauts landing on the lunar surface along with anticipated deliveries of lunar habitat modules and lunar rovers, as well.

“Moreover, the Artemis mission is targeting the lunar south pole for its landing sites,” Dr. Kurt tells Universe Today. “This region is of particular interest due to the presence of peaks of eternal light (PELs), which receive almost continuous sunlight and permanently shadowed regions (PSRs), which are potential sites for resources such as water ice. These contrasting conditions are ideal for the application of wireless energy transmission (laser power beaming technology), which could provide a continuous power supply in shadowed areas by transmitting energy wirelessly from illuminated regions.”

The reason these PSRs exist is due to the Moon’s low obliquity, or axial tilt, which the study notes is 6.68 degrees. For context, the Earth’s obliquity is 23.44 degrees. This means there are areas, and specifically craters, at both the north and south poles on the Moon that do not receive any sunlight, hence the name “permanently shadowed regions”. As noted by Dr. Kurt, these PSRs could be home to deposits of water ice within these deep, dark craters that astronauts could use for water, fuel, and other needs.

The Artemis missions plan to deliver not only astronauts to the lunar surface, but a habitat and lunar rovers with the goal of establishing a permanent human presence on the Moon. This will provide opportunities for demonstrating new space technologies that can be used for both lunar exploration and future human missions to Mars, which are a part of NASA’s Moon to Mars Architecture.

“Current missions plan to re-use Earth-proven technology,” Dr. Kurt tells Universe Today. “This mindset may undermine the blue-sky design approach, where researchers are encouraged to think freely, explore creative ideas, and push the boundaries of what’s possible without being confined by constraints such as specific project requirements or backward compatibility. In our work we aim to include multi-functionality aspects, which are not a necessity for terrestrial applications but may turn out to be essential for future space missions.”

How will this wireless power transmission method help improve communication from the far side of the Moon to Earth in the coming years and decades? Only time will tell, and this is why we science!

As always, keep doing science & keep looking up!

Millions of people took a trip over to the US or Mexico to try and catch a glimpse of the 2024 total solar eclipse. Whether you took the trip or not, if you have since been bitten by the eclipse bug then there are three upcoming eclipses over the next couple of years. August 2026 sees an eclipse passing from Greenland, Iceland and Spain, 2027 sees an eclipse over North Africa and in 2028 Australia all be the place to be. With loads of possibilities for all locations, it’s time to get planning. 

Many people across the World make attempts to witness solar eclipses, often travelling hundreds if not thousands of kilometres. I tried such a journey back in 1999 travelling from my home in Norfolk, UK to Cornwall, a journey of over 600 kilometres. Alas, and like many eclipse chasers before me, cloud thwarted my view. However, the experience of the daylight turning to dusk in a few seconds at the onset of totality, the birds singing as the ‘Sun came out again’, it was all such an incredible amazing experience. 

Since that cloudy experience in Cornwall I committed to one day, actually seeing a total solar eclipse. I have seen partials, and they are wonderful but nothing like the majesty of a total solar eclipse.

What are we talking about? Well, the Moon travels around the Earth and the Earth travels around the Sun. It’s these changing relative positions that lead to the lunar phases. When the Moon is broadly between the Sun and Earth we experience a new moon phase. You might therefore wonder why we don’t experience a total solar eclipse every new moon! The answer lies in the obits; the orbit of the Moon around Earth is tilted by about 5 degrees in reference to the Earth’s orbit around the Sun. During most new moons the Moon is slightly above or below the Sun when viewed from Earth. It’s only when the two orbits intersect at a new moon that we see a total solar eclipse. 

This is exactly what happened on 8 April 2024, a total solar eclipse became visible as the Moon silently passed directly between the Earth and Sun. When we get a perfect alignment of three celestial bodies like this its called a Syzygy, a wonderful word and great for a game of Scrabble. Totality for this eclipse lasted for about 4 minutes depending on the location of the observer. That’s the chief difference between a solar eclipse and a lunar eclipse. Lunar eclipses are visible anywhere on Earth that the Moon is visible but solar eclipses are only visible from very specific locations on Earth. 

Over the next few years there are some great opportunities to see total solar eclipses. Unless you are lucky, you will have to travel but the next opportunity takes place on 12 August 2026. You will need to be travelling to either Greenland, Iceland or Spain to catch this eclipse. Greenland and Iceland are the best option as Spain will only get the eclipse toward the end of the day. Next up is 2027 when an eclipse takes place on the 2 August visible from North Africa. After that, it’s 2028 but for southern hemisphere observers so its a trip to Australia. 

Wherever you venture to observe a total solar eclipse, it is imperative that you be careful when observing it. The ONLY time it is safe to observe a solar eclipse directly is during the moments of totality. As soon as the bright parts of the solar photosphere are visible, then direct observing is dangerous and will lead to damage to your eyes. If you are planning a trip to observe a total solar eclipse, be sure you are prepared and know exactly when and how you can observe it to ensure your eyesight remains safe.

The post Here are the Next Three Total Solar Eclipses Coming Up appeared first on Universe Today.

It’s a measure of human ingenuity and curiosity that scientists debate the possibility of life on Venus. They established long ago that Venus’ surface is absolutely hostile to life. But didn’t scientists find a biomarker in the planet’s clouds? Could life exist there, never touching the planet’s sweltering surface?

It seems to depend on who you ask.

We’ll start with phosphine.

Phosphine is a biomarker, and in 2020, researchers reported the detection of phosphine in Venus’ atmosphere. There should be no phosphine because phosphorous should be oxidized in the planet’s atmosphere. According to the paper, no abiotic source could explain the quantity found, about 20 ppb.

Subsequently, the detection was challenged. When others tried to find it, they couldn’t. Also, the original paper’s authors informed everyone of an error in their data processing that could’ve affected the conclusions. Those authors examined the issue again and mostly stood by their original detection.

At this point, the phosphine issue seems unsettled. But if it is present in Venus’ atmosphere and is biological in nature, where could it be coming from? Venus’s surface is out of the question.

That leaves Venus’ cloud-filled atmosphere as the only abode of life. While the idea might seem ridiculous at first glance, researchers have dug into the idea and generated some interesting results.

In a new paper, researchers examine the idea of microscopic life that lives and reproduces in water droplets in Venus’s clouds. The title is “Necessary Conditions for Earthly Life Floating in the Venusian Atmosphere.” The lead author is Jennifer Abreu from the Department of Physics and Astronomy, Lehman College, City University of New York. The paper is currently in pre-print.

Spacecraft have struggled to contend with the harsh conditions on Venus’s surface. The Soviet Venera 13 lander captured this image of the planet’s surface in March of 1982. NASA/courtesy of nasaimages.org

“It has long been known that the surface of Venus is too harsh an environment for life,” the authors write. “Contrariwise, it has long been speculated that the clouds of Venus offer a favourable habitat for life but regulated to be domiciled at an essentially fixed altitude.” So, if life existed in the clouds, it wouldn’t be spread throughout. Only certain altitudes appear to have what’s needed for life to survive.

The type of life the authors envision aligns with other thinking about Venusian atmospheric life. “The archetype living thing <being> the spherical hydrogen gasbag isopycnic organism,” they state. (Isopycnic means constant density; the other terms are self-explanatory.)

Here’s how the authors think it could work.

Venus is shrouded in clouds so thick we can only see the surface with radar. The clouds reach all the way around the globe. The cloud base is about 47 km (29 miles) from the surface, where the temperature is about 100 C (212 F.) At equatorial and mid-latitudes, they extend up to a 74 km (46 miles) altitude, and at the poles, they extend up to about 65 km (40 miles.)

The clouds can be subdivided into three layers based on the size of aerosol particles: the upper layer from
56.5 to 70 km altitude, the middle layer from 50.5 to 56.5 km, and the lower layer from 47.5 to 50.5 km. The smallest droplets can float in all three layers. But the largest droplets, which the authors call type 3 droplets with a radius of 4 µm, are only present in the middle and lower layers.

“It has long been suspected that the cloud decks of Venus offer an aqueous habitat where microorganisms can grow and flourish,” the authors write. Everything life needs is there: “Carbon dioxide, sulfuric acid compounds, and ultraviolet (UV) light could give microbes food and energy.”

Because of temperature, life in Venus’ clouds would be restricted to a specific altitude range. At 50 km, the temperature is between 60 and 90 degrees Celsius (140 and 194 degrees Fahrenheit). The pressure at that altitude is about 1 Earth atmosphere.

This figure from the research shows the temperature and pressure throughout Venus’s atmosphere. Image Credit: Image Credit: S. Seager et al. 2021. doi:10.1089/ast.2020.2244

There’s a precedent for life existing in the clouds. It happens here on Earth, where scientists have observed bacteria, pollen, and even algae at altitudes as high as 15 km (9.3 miles.) There’s even evidence of bacteria growing in droplets in a super-cooled cloud high in the Alps. The understanding is that these organisms were carried aloft by wind, evaporation, eruptions, or even meteor impacts. But there’s an important difference between Earth’s and Venus’ clouds.

Earth’s clouds are transient. They form and dissolve constantly. But Venus’ clouds are long-lasting. They’re a stable environment compared to Earth’s clouds. In Earth’s clouds, aerosol particles are sustained for only a few days, while in Venus’ clouds, the particles can be sustained for much longer periods of time.

Add it all up, and you get stable cloud environments where aerosol particles can sustain themselves in an environment where energy and nutrients are available. The researchers say that though eventually aerosol particles and the life within them will fall to the surface, they have time to reproduce before that happens.

This image shows the cycle of Venusian aerial microbial life. Image Credit: S. Seager et al. 2021. doi:10.1089/ast.2020.2244

The idea of a microbial life cycle in Venusian clouds was developed by other researchers in their 2021 paper “The Venusian Lower Atmosphere Haze as a Depot for Desiccated Microbial Life: A Proposed Life Cycle for Persistence of the Venusian Aerial Biosphere.”

There are five steps in Venus’s proposed cloud lifecycle:

1. Dormant desiccated spores (black blobs) partially populate the lower haze layer of the atmosphere.
2. Updrafts transport them up to the habitable layer. The spores could travel up to the clouds via gravity waves.
3. Shortly after reaching the (middle and lower cloud) habitable layer, the spores act as cloud condensation nuclei, and more and more water gathers into a single droplet. Once the spores are surrounded by liquid with the necessary chemicals, they germinate and become metabolically active.
4. Metabolically active microbes (dashed blobs) grow and divide within liquid droplets (shown as solid circles in the figure). The liquid droplets continue to grow by coagulation.
5. Eventually, the droplets are large enough to settle out of the atmosphere gravitationally; higher temperatures and droplet evaporation trigger cell division and sporulation. The spores are smaller than the microbes and resist further downward sedimentation. They remain suspended in the lower haze layer (a depot of hibernating microbial life) to restart the cycle.

In this new work, the researchers focus on time.

“One of the key assumptions of the aerial life cycle put forward in Seager et al. 2021 is the timescale on which droplets would persist in the habitable layer to empower replication,” the authors write. “It is this that we now turn to study.”

This table from the research shows generation times for some common Earth bacteria. Image Credit: Abreu et al. 2024.

The authors used E. Coli generation times under optimal conditions in their work. In aerobic and nutrient-rich conditions, E. Coli can reproduce in 20 minutes. So, the E. Coli population will double three times in one hour. Bacteria must reproduce faster than they fall to the surface to sustain itself. They need to form a colony.

The researchers calculated that to sustain itself, the time it takes for bacteria to fall from the habitable part of the atmosphere to the inhabitable has to be longer than half an Earth day. As droplet size increases, the droplets would begin to sink. “As the droplet size approaches 100 µm, the droplets would start sinking to the lower haze layers,” they explain. However, their detailed calculations show that reproduction outpaces the fallout rate.

According to the team’s work, a population of bacteria could sustain itself in Venus’ clouds.

There are, obviously, still some questions. How certain are we that nutrients are available? Is there enough energy? Are there updrafts that can loft spores into the right layer of the atmosphere?

But the real big question is how was this all set in motion?

“An optimist might even imagine that the microbial life actually arose in a good-natured surface habitat, perhaps in a primitive ocean, before the planet suffered a runaway greenhouse, and the microbes lofted into the clouds,” the authors write. If that’s the case, this unique situation arose billions of years ago. Is there any other possibility? Could life have originated in the clouds?

Much scientific investigation into Venus, phosphine, clouds, and life relies on scant evidence. Few are willing to go out on a limb and proclaim that Venus can and does support life. We need more evidence.

For that, we have to wait for missions like the Venus Life Finder Mission. It’s a private mission being developed by Rocket Lab and a team from MIT. Who knows what VLF and other missions like DAVINCI and VERITAS will find? Stronger evidence of phosphine? Better data on Venus’ atmospheric layers and the conditions in them?

Life itself?

On April 8, 2024, Peter Higgs passed away. Pioneering the discovery of the Higgs boson, the mark the theoretical physicist has left on physics is immense.

Jupiter and a slim crescent moon are the stand-out night sky sight in the evening sky right now.

Pink Floyd was wrong, there is no dark side to the Moon. There is however, a far side. The tidal effects between the Earth and Moon have caused this captured or synchronous rotation. The two sides display very different geographical features; the near side with mare and ancient volcanic flows while the far side displaying craters within craters. New research suggests the Moon has turned itself inside out with heavy elements like titanium returning to the surface. It’s now thought that a giant impact on the far side pushed titanium to the surface, creating a thinner more active near side. 

There have been a number of theories for the formation of the Moon; the capture theory and the accretion theory to name two of them. Perhaps the most accepted theory now is the giant impact theory which suggests Earth was struck by a large object, causing a lot of debris to be ejected into orbit. This material eventually coalesced to form the Moon we know and love today. 

In the decades that followed the Apollo missions, scientists studied the rocks returned by the astronauts. The studies revealed that many of the surface rocks contained unexpectedly high concentrations of titanium. More surprisingly was that satellite observations revealed these titanium rich minerals were far more common on the nearside and absent on the far-side. What is known is that the Moon formed fast and hot and would have been covered for a short period in an ocean of molten magma. The magma cooled and solidified forming the Moon’s crust but trapped below was the more dense material including titanium and iron.

The dense material should have sunk to greater depths inside the Moon however over the years that followed something strange seems to have happened. The denser material did indeed sink, mixed with mantle but melted and returned to the surface as titanium rich lava flows. Debates have been raging whether this is exactly what happened but a new piece of research by a team at the University of Arizona Lunar and Planetary Laboratory offer more details about the process and how the interior of the Moon evolved.

It has already been suggested that the Moon may have suffered a giant impact on the far side causing the heavier elements to be forced over to the near side but the new study highlighted supporting evidence from gravitational anomalies. The team measured tiny variations in the Moon’s gravitational field from data from the GRAIL mission. GRAIL – or Gravity Recovery and Interior Laboratory – orbited the Moon to create the most accurate gravitational map of the Moon to date. Using GRAIL data the team discovered that titanium-iron oxide minerals had migrated to the near side and sunk to the interior in sheetlike cascades. This was consistent with models suggesting the event occurred more than 4.22 billion years ago.

As paper co-author and LPL associate professor Jeff Andrews-Hanna said “The moon is fundamentally lopsided in every respect.” The near side feature known as Oceanus Procellarum is a great example. It is lower in elevation and has a lava flow covered thinner crust with high concentrations of titanium rich elements. This is very different on the far side. The strange and unique structure of the region is thought to be key in understanding the event that happened billions of years ago to shape the Moon we see today.

Seventy teams from 24 states and Puerto Rico are participating this year with 53 teams expected to launch in-person. Any team not traveling to Alabama may conduct final test flights at a home launch field.

NASA also welcomes the return of the Rocket Fair on April 12 from 3-6 p.m. at the Von Braun Center East Hall in downtown Huntsville. This event is free and open to the public as students display their rockets and answer questions from the media and NASA engineers.

Schedule of Events

• April 12: Rocket Fair at the Von Braun Center East Hall.
• April 13: Launch Day, gates open at 7 a.m. The event runs from 8:30 a.m. to approximately 2:30 p.m. (or until the last rocket launch) at Bragg Farms. Lawn chairs are recommended. Pets are not permitted.
• April 14:  Tentative rain day on Sunday in case of inclement weather on April 13 starting at 8:30 a.m. at Bragg Farms.

Winners of the student launch will be announced on June 7 during a virtual awards ceremony once all teams’ flight data has been verified.

Student Launch provides relevant, cost-effective research and development of rocket propulsion systems and reflects the goals of NASA’s Artemis campaign, which seeks to put the first woman and first person of color on the Moon.

Each year, the payload component changes to reflect current NASA missions. This year’s payload challenge is inspired by the Artemis missions.

Students will design a SAIL (STEMnaut Atmosphere Independent Lander) payload. It must deploy mid-air, safely return to the ground without using a parachute, and be reusable to launch the same day without repairs or modifications. The payload will contain a crew of STEMnauts, four non-living objects representing astronauts. Students will choose metrics to determine the endurance of the lander, considering acceptable descent and landing parameters.

Middle and high school teams can choose to attempt the lander payload or develop their own science or engineering experiment.

Eligible teams compete for prizes and awards and are scored in nearly a dozen categories including safety, vehicle design, social media presence, and science, technology, engineering, and math (STEM) engagement. Teams can also win the Altitude Award in each division based on how close they get to the altitude they projected their rockets would reach months in advance to launch day.

Marshall’s Office of STEM Engagement hosts Student Launch to encourage students to pursue careers in STEM through real-world experiences. Student Launch is a part of the agency’s Artemis Student Challenges – a variety of activities exposing students to the knowledge and technology required to achieve the goals of the Artemis missions.

In addition to the NASA Office of STEM Engagement’s Next Gen STEM project, NASA Space Operations Mission Directorate, Northrup Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space and Bastion Technologies provide funding and leadership for the competition.

Michoud Site Recovery Team Receives NASA’s Silver Group Achievement Award

By Heather Keller

The High Voltage Hurricane Ida Site Recovery Team at NASA’s Michoud Assembly Facility was awarded the agency’s Silver Group Achievement Award on March 18. The team of seven was recognized for “exemplary employee dedication and perseverance ensuring the safety of site, SLS (Space Launch System) hardware, and personnel” onsite post landfall of the category 4 storm.

Hurricane Ida made landfall in southeast Louisiana on Aug. 29, 2021, causing catastrophic failure of high voltage infrastructure and leaving most of the city of New Orleans without power for several weeks. Michoud received major damage from the storm’s 112 mph wind gusts and sustained winds of 80 mph. Immediately after landfall, the Michoud High Voltage Team methodically and safely energized the 6 MW emergency generator while procedurally transferring power to the facility’s east and west master substations. The transfer provided critical power to the rocket factory’s final assembly area while coordinating with the SLS Program and Boeing.

The critical transfer also provided essential power for SLS purges for Engine Section and Clean Work Areas to ensure the safety of flight hardware components. The team also provided power for lighting, allowing the Boeing teams to conduct critical inspections of flight hardware for damages.

The team also set up and provided emergency generator power for critical site infrastructure, such as the Coast Guard Exchange (CGX), which provided fuel for response and recovery personnel and other necessary supplies.

The High Voltage Team collaborated with Entergy New Orleans to determine a timeline for Michoud to accept line voltage from the site’s generating station and was successful in accepting power five days post-landfall. They systematically worked to safely bring additional loads online as prioritized and requested by Boeing and the SLS Program with more than 35 buildings receiving power approximately eight days post hurricane and allow site opening for tenant access.

Dr. Sterry: Be Aware of Increase in Alcohol Abuse Rates Post COVID

Dear Marshall family,

April is Alcohol Awareness Month, and recent data indicate the rates of alcohol abuse and deaths resulting from it have risen dramatically over the past few years.

Very early during the COVID-19 pandemic it became apparent that sales of alcohol were increasing, and so it has been expected that the negative impacts related to this issue would increase as well. But I don’t think anyone anticipated just how much they would increase. I understand your first inclination might be to skip over this, but it’s a quick read, so please take a moment to consider the situation for the sake of your family, friends, and co-workers.

Data from 2020–2021, published by the Centers for Disease Control and Prevention, indicate that 178,000 people died in the U.S. from alcohol abuse and related health problems during that period. This represents a 29% increase from 2016–2017, when there were an estimated 138,000 deaths. Similarly disturbing, data published by the National Institute on Alcohol Abuse and Alcoholism indicate that rates of alcohol use disorder rose from 14.5 million adults in the U.S. in 2019 to 29.5 million in 2022.

Since a majority of adults in the U.S. drink alcoholic beverages on occasion, it is becoming even more important to be mindful of how to reduce the risks of negative impacts on our health, and on our lives, in general. The U.S. Department of Agriculture offers guidelines for alcohol consumption geared toward limiting those risks: no more than one standard drink per day for women, and no more than two standard drinks per day for men. While the difference in the numbers may seem unfair, they are based primarily upon body mass and metabolism rates.

What constitutes a “standard drink” depends upon what you’re drinking. For example, for beer, it is 12 fluid ounces, for wine, it is 5 fluid ounces, and for liquor, it is 1.5 fluid ounces. While being mindful of the number of drinks we’re consuming, it’s also important to keep in mind that even within any given category or type of drink, the percentage of alcohol can vary significantly from one product to another. For example, in Alabama, beer can contain up to 13.9% alcohol, and wine can contain up to 24%.

I have two requests of you today. First, please be mindful of how much you’re drinking, and be deliberate in reducing your risks, if needed. If you’d like to do a quick assessment of your drinking, an anonymous self-report test is available at https://auditscreen.org/check-your-drinking. Also, please consider sharing this information with any of your family members and friends that you think might be at risk for the health problems and other dangers associated with alcohol abuse.

If you’d like to get more information about alcohol abuse, and the dangers associated with it, a few good resources include:

NASA Achieves Milestone for Engines to Power Future Artemis Missions

NASA achieved a major milestone April 3 for production of new RS-25 engines to help power its Artemis campaign to the Moon and beyond with completion of a critical engine certification test series at NASA’s Stennis Space Center.

The 12-test series represents a key step for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to build new RS-25 engines, using modern processes and manufacturing techniques, for NASA’s SLS (Space Launch System) rockets that will power future lunar missions, beginning with Artemis V.

NASA conducted a full-duration RS-25 hot fire April 3 on the Fred Haise Test Stand at the agency’s Stennis Space Center, achieving a major milestone for future Artemis flights of NASA’s SLS (Space Launch System) rocket. It marked the final test of a 12-test series to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, to help power SLS on Artemis missions to the Moon and beyond, beginning with Artemis V.NASA/Danny Nowlin

“The conclusion of the certification test series at NASA Stennis is just the beginning for the next generation of RS-25 engines that will help power human spaceflight for Artemis,” said Johnny Heflin, SLS liquid engines manager. “The newly produced engines on future SLS rockets will maintain the high reliability and safe flight operational legacy the RS-25 is known for while enabling more affordable high-performance engines for the next era of deep space exploration.”

Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon; land the first woman, first person of color, and first international partner astronaut on the lunar surface; and prepare for human expeditions to Mars for the benefit of all.

Contributing to that effort, the NASA Stennis test team conducted a full-duration, 500-second hot fire to complete the 12-test series on developmental engine E0525, providing critical performance data for the final RS-25 design certification review. The April 3 hot fire completed a test series that began in October 2023.

RS-25 engines are evolved space shuttle main engines, upgraded with new components to produce the additional power needed to help launch NASA’s SLS rocket. The first four Artemis missions are using modified space shuttle main engines also tested at NASA Stennis. For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power the SLS rocket, producing more than 8.8 million pounds of total combined thrust at liftoff.

“This was a critical test series, and credit goes to the entire test team for their dedication and unique skills that allowed us to meet the schedule and provide the needed performance data,” said Chip Ellis, project manager for RS-25 testing at NASA Stennis. “The tests conducted at NASA Stennis help ensure the safety of our astronauts and their future mission success. We are proud to be part of the Artemis mission.”

The E0525 developmental engine featured new key components – including a nozzle, hydraulic actuators, flex ducts, and turbopumps – that matched design features of those used during an initial certification test series completed at NASA Stennis last summer.

The two certification test series helped verify the new engine components meet all Artemis flight requirements moving forward. Aerojet Rocketdyne is using techniques such as 3D printing to produce new RS-25 engines more efficiently, while maintaining high performance and reliability. NASA has awarded the company contracts to provide 24 new engines, supporting SLS launches for Artemis V through Artemis IX.

“Successfully completing this rigorous test series is a testament to the outstanding work done by the team to design, implement and test this upgraded version of the RS-25 that reduces the cost by 30% from the space shuttle program,” said Mike Lauer, RS-25 program director at Aerojet Rocketdyne. “We tested the new RS-25 engines to the extreme limits of operation to ensure the engines can operate at a higher power level needed for SLS and complete the mission with margin.”

RS-25 Final Certification Test Series by the Numbers

All RS-25 engines are tested and proven flightworthy at NASA Stennis prior to use on Artemis missions. RS-25 tests at the center are conducted by a diverse team of operators from NASA, Aerojet Rocketdyne, and Syncom Space Services, prime contractor for site facilities and operations.

Agency Selects Companies to Advance Moon Mobility for Artemis Missions

NASA has selected Intuitive Machines, Lunar Outpost, and Venturi Astrolab to advance capabilities for a lunar terrain vehicle (LTV) that Artemis astronauts will use to travel around the lunar surface, conducting scientific research during the agency’s Artemis campaign at the Moon and preparing for human missions to Mars.

The awards leverage NASA’s expertise in developing and operating rovers to build commercial capabilities that support scientific discovery and long-term human exploration on the Moon. NASA intends to begin using the LTV for crewed operations during Artemis V.

“We look forward to the development of the Artemis generation lunar exploration vehicle to help us advance what we learn at the Moon,” said Vanessa Wyche, director of NASA’s Johnson Space Center. “This vehicle will greatly increase our astronauts’ ability to explore and conduct science on the lunar surface while also serving as a science platform between crewed missions.”

NASA will acquire the LTV as a service from industry. The indefinite-delivery/indefinite-quantity, milestone-based Lunar Terrain Vehicle Services contract with firm-fixed-price task orders has a combined maximum potential value of $4.6 billion for all awards. 

Each provider will begin with a feasibility task order, which will be a year-long special study to develop a system that meets NASA’s requirements through the preliminary design maturity project phase. The agency will issue a subsequent request for task order proposal to eligible provider(s) for a demonstration mission to continue developing the LTV, deliver it to the surface of the Moon, and validate its performance and safety ahead of Artemis V. NASA anticipates making an award to only one provider for the demonstration. NASA will issue additional task orders to provide unpressurized rover capabilities for the agency’s moonwalking and scientific exploration needs through 2039.

The LTV will be able to handle the extreme conditions at the Moon’s South Pole and will feature advanced technologies for power management, autonomous driving, and state of the art communications and navigation systems. Crews will use the LTV to explore, transport scientific equipment, and collect samples of the lunar surface, much farther than they could on foot, enabling increased science returns.

Between Artemis missions, when crews are not on the Moon, the LTV will operate remotely to support NASA’s scientific objectives as needed. Outside those times, the provider will have the ability to use their LTV for commercial lunar surface activities unrelated to NASA missions.

“We will use the LTV to travel to locations we might not otherwise be able to reach on foot, increasing our ability to explore and make new scientific discoveries,” said Jacob Bleacher, chief exploration scientist in the Exploration Systems Development Mission Directorate at NASA Headquarters. “With the Artemis crewed missions, and during remote operations when there is not a crew on the surface, we are enabling science and discovery on the Moon year around.”

NASA provided technical requirements, capabilities, and safety standards needed for LTV development and operations, and the selected companies have agreed to meet the key agency requirements. The contract request for proposal required each provider to propose a solution to provide end-to-end services, including LTV development, delivery to the Moon, and execution of operations on the lunar surface.

Through Artemis, NASA will send astronauts – including the first woman, first person of color, and its first international partner astronaut – to explore the Moon for scientific discovery, technology evolution, economic benefits, and to build the foundation for crewed missions to Mars. Advanced rovers, along with the agency’s SLS (Space Launch System) rocket and Orion spacecraft, commercial human landing systems and next-generation spacesuits, and Gateway are NASA’s foundation for deep space exploration.

Hubble Peers at Pair of Closely Interacting Galaxies

An image from the NASA/ESA Hubble Space Telescope features Arp 72, a very selective galaxy group that only includes two galaxies interacting due to gravity: NGC 5996 (the large spiral galaxy) and NGC 5994 (its smaller companion, in the lower left of the image).

This NASA/ESA Hubble Space Telescope image features Arp 72.ESA/Hubble & NASA, L. Galbany, J. Dalcanton, Dark Energy Survey/DOE/FNAL/DECam/CTIO/NOIRLab/NSF/AURA

Both galaxies lie approximately 160 million light-years from Earth, and their cores are separated from each other by a distance of about 67,000 light-years. The distance between the galaxies at their closest points is even smaller, closer to 40,000 light-years.

While this might sound vast, in galactic separation terms it is quite close. For comparison, the distance between the Milky Way and its nearest independent galactic neighbor Andromeda is around 2.5 million light-years. Alternatively, the distance between the Milky Way and its largest and brightest satellite galaxy, the Large Magellanic Cloud (satellite galaxies orbit around another galaxy), is about 162,000 light-years.

Given this and the fact that NGC 5996 is comparable in size to the Milky Way, it is not surprising that NGC 5996 and NGC 5994 – separated by only about 40,000 light-years – are interacting with one another. In fact, the interaction likely distorted NGC 5996’s spiral shape. It also prompted the formation of the very long and faint tail of stars and gas curving away from NGC 5996, up to the top right of the image. This “tidal tail” is a common phenomenon that appears when galaxies closely interact and is visible in other Hubble images of interacting galaxies.

NASA Administrator Bill Nelson and Japan’s Minister of Education, Culture, Sports, Science and Technology (MEXT) Masahito Moriyama have signed an agreement to advance sustainable human exploration of the Moon.

Japan will design, develop, and operate a pressurized rover for crewed and uncrewed exploration on the Moon. NASA will provide the launch and delivery of the rover to the Moon as well as two opportunities for Japanese astronauts to travel to the lunar surface.

Today, President Biden and Prime Minister Kishida also announced, “a shared goal for a Japanese national to be the first non-American astronaut to land on the Moon on a future Artemis mission, assuming important benchmarks are achieved.”

The pressurized lunar rover is intended to enable astronauts to travel farther and work for longer periods on the lunar surface. The signing took place April 9 at NASA Headquarters in Washington. Along with Nelson and Moriyama, JAXA (Japan Aerospace Exploration Agency) President Hiroshi Yamakawa also participated in the signing.

“The quest for the stars is led by nations that explore the cosmos openly, in peace, and together. This is true for the United States and Japan under the leadership of President Biden and Prime Minister Kishida,” said Nelson. “America no longer will walk on the Moon alone. With this new rover, we will uncover groundbreaking discoveries on the lunar surface that will benefit humanity and inspire the Artemis Generation.”

An enclosed and pressurized rover will enable astronauts to travel farther and conduct science in geographically diverse areas by serving as a mobile habitat and laboratory for the astronauts to live and work for extended periods of time. It will be able to accommodate two astronauts for up to 30 days as they traverse the area near the lunar South Pole. NASA currently plans to use the pressurized rover on Artemis VII and subsequent missions over an approximate 10-year lifespan.

“It was an honor to sign the historic implementing arrangement that will be long remembered as the symbol of the new era of Japan-U.S. partnership for the lunar exploration,” said Moriyama. “Under the partnership stronger than ever, we will drive the initiative together with JAXA, including the development of the pressurized rover that vastly extends the exploration capability on the lunar surface, to realize the shared goal for Japanese and American astronauts to, together, explore the moon.”

The arrangement falls under the “Framework Agreement Between the Government of Japan and the Government of the United States of America for Cooperation in Space Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies, For Peaceful Purposes,” which was signed in January 2023 and recognizes the nations’ mutual interest in peaceful exploration.

The framework agreement facilitates a broad swath of joint activities between the countries, including space science, Earth science, space operations and exploration, aeronautical science and technology, space technology, space transportation, safety, and mission assurance, and much more. In addition to the agreement for lunar surface exploration, the partners will build on the framework agreement with future agreements for Japan’s participation in NASA’s Dragonfly mission and the Nancy Grace Roman Space Telescope. The U.S. and Japan also intend to collaborate on JAXA’s Next-generation Solar-observing Satellite, SOLAR-C, which will investigate the mysteries of solar atmospheres by conducting observations of ultraviolet radiation from the Sun.

“The pressurized rover will be a powerful contribution to the overall Artemis architecture as Japan and the U.S. go hand in hand with international and industry partners to the lunar surface and beyond,” said Yamakawa. “JAXA is ready to assist MEXT and push this forward with our science and technological expertise to establish sustainable human presence on the Moon.”

Under the Gateway Implementing Arrangement signed in 2022, NASA will also provide an opportunity for a Japanese astronaut to serve as a Gateway crew member on a future Artemis mission and Japan will provide Gateway’s environmental control and life support systems and cargo transportation.

Through Artemis, NASA will land the first woman, first person of color, and its first international partner astronaut on the Moon, make new scientific discoveries, and explore more of the lunar surface than ever before for the benefit of all.

2 Min Read More Than 36,000 Volunteers Helped Do NASA Eclipse Science

SunSketcher volunteers captured sequences of eclipse images, revealing the precise size and shape of the Sun and testing theories of gravity!

Thank you for helping us out! Over 36,000 people helped do NASA Science during Monday’s total solar eclipse. Together, these volunteers submitted more than 60,000 vital pieces of eclipse data to NASA science projects.

More than 30,000 volunteers with the SunSketcher project pointed their smartphones toward the Sun and recorded pictures of Bailey’s beads, flashes of Sunlight coming through valleys on the moon. These pictures will reveal the size and shape of the Sun to high precision.

Volunteers with GLOBE Observer (GO) submitted more than 35,000 data points to the GO Eclipse, GO Clouds, and GO Landcover projects, taking eclipse data using their cell phones and sometimes thermometers. These data show the effect of the eclipse on our atmosphere.

Many more volunteers used specialized gear—DSLR cameras, telescopes, audiomoth recorders, and Ham Radio sets—taking data for the Dynamic Eclipse Broadcast Initiative, the Eclipse Megamovie project, Citizen CATE 2024, Eclipse Soundscapes, and the HamSCI project. These data will trace plumes and ejections of matter in the solar corona, track waves in the ionosphere, and reveal how animals, birds and insects reacted to the eclipse. 

“I’m fascinated by the idea that the eclipse can affect the behavior of animals!” said one Eclipse Soundscapes volunteer. “I hope you all get a good data set and am still very excited to see the results! It was awesome!” said a SunSketcher volunteer. 

Science is a methodical process and sometimes a slow process. Data are still arriving from cell phones and computers around the country. It will probably take months or even years for scientists to check and analyze the data, compare it with data on previous eclipses, and publish it in the refereed scientific literature. 

But stay tuned as the Heliophysics Big Year continues! There will probably be some beautiful pictures coming out in the days and weeks to come thanks to your efforts.

3 Min Read A Langley Intern Traveled 1,340 Miles to View a Total Solar Eclipse. Here’s What She Saw. Emma Friedman, an intern with the Office of Communications at NASA's Langley Research Center, traveled to Dallas, Texas, to observe the total solar eclipse on April 8, 2024. Credits: NASA/Emma Friedman

Emma Friedman, an Office of Communications intern at NASA’s Langley Research Center in Hampton, Virginia, understood that the total solar eclipse on April 8th, 2024, was an out-of-this-world opportunity she couldn’t miss.

Equipped with the proper eye protection, I traveled over one thousand miles to Dallas, Texas, to be in the eclipse’s path of totality. As I got situated in a park near the city, I was excited—I’d read books and seen photos of what an eclipse looked like and knew what to expect, but I also knew that seeing it in person would be something greater than fiction. Slowly but surely, the Moon took more and more “bites” out of the sun, until I saw the last little peek of light before the darkness; this is known as the “diamond ring effect.”

As she waited for 100% totality during the 2024 total solar eclipse, Emma captured this image of crescent-shaped shadows cast by tree leaves. During an eclipse, light from the Sun passes through small gaps between tree leaves, creating a natural pinhole camera effect; images of the eclipse are then projected onto the surface below.NASA / Emma Friedman

Before I had time to process any of it, the hairs on the back of my neck stood up. A silence fell across the park—even the birds stopped chirping—and I held my breath. All you could hear was the rustling of branches. What was a warm spring day was now a cold, dark dusk. It felt like the world had flipped on its head—first slowly, and then all at once. What the Sun had just seconds before lit was now a black void. The glow I saw around the Sun was its outer atmosphere, known as the corona. It was a moving sight, but why did I travel so far to experience it? Surely a viewing of a total eclipse was not in need of a plane ride.

It’s actually more complicated than simply waiting for the Moon to drift in front of the Sun. You have to be in the right place at the right time in a region called the “path of totality.”

The total solar eclipse will be visible along a narrow track stretching from Texas to Maine on April 8, 2024. A partial eclipse will be visible throughout all 48 contiguous U.S. states.

As a Maryland local, seeing a total solar eclipse from my home would be impossible during this eclipse. Despite eclipses being relatively common, it is a bit more challenging to see the Moon totally block out our Sun.
I spoke to Atmospheric Scientist and expert, Marilé Colón Robles, about the so-called “eclipse chasing” people like me took part in.

“Solar eclipses happen every eighteen months or so, so they are pretty common. To see a total solar eclipse is more challenging because a limited amount of the Earth’s surface is in the path of totality at any given time. Because the world is mostly made up of oceans, your chances of seeing a total eclipse from where you live is small. If, by chance, a total eclipse is happening near you, it’s best to travel to it.”

One team from NASA Langley did something similar by traveling to Houlton, Maine, to broadcast the eclipse in the path of totality. The broadcast showcases the moments before, during, and after the total solar eclipse. Another team of researchers from NASA Langley traveled to Fort Drum, N.Y., also located in the path of totality, to study changes in the weather during the total solar eclipse using a specially modified drone flying at 10,000 feet.

You can see my time lapse of the total solar eclipse below. Needless to say, the plane ride was worth it, and I was fortunate to enjoy one of the most cinematic and humbling phenomena that an Earthling can experience.
