The Oceans on Enceladus Are Highly Alkaline
What can the pH level of the subsurface ocean on Enceladus tell us about finding life there? This is what a recent study accepted to Icarus hopes to address as a team of researchers investigated the potential pH level of Enceladus’ subsurface ocean based on current estimates. This study has the potential to help scientists better understand the composition of Enceladus’ subsurface ocean and what this can mean for finding life as we know it.
Worldwide Team of Citizen Scientists Help Confirm a Tricky Exoplanet
Distant exoplanets can be dodgy to spot even in the best of observations. Despite the challenges, a team of astronomers just reported the discovery of a gas giant exoplanet that lies about 400 light-years from Earth. It's called TOI-4465 b and it takes 12 hours to transit across the face of its star during its 102-day orbit.

Antarctic waters getting saltier as sea ice wanes
Using data from ESA’s SMOS satellite, scientists have revealed a surprising shift in the Southern Ocean – surface waters around Antarctica are growing saltier, even as sea ice is diminishing rapidly. This finding defies the norm because melting ice typically freshens ocean surface water.
The implications are far-reaching as changes in this remote region can disrupt global ocean currents, affect climate patterns, and alter ecosystems far beyond the Antarctic.
NASA Remembers Former Johnson Director Jefferson Howell
July 3, 2025
Jefferson Davis Howell, Jr., former director of NASA’s Johnson Space Center in Houston, died July 2, in Bee Cave, Texas. He was 85 years old.
Howell was a champion of the construction of the International Space Station, working on a deadline to complete the orbiting lab by 2004. He oversaw four space shuttle crews delivering equipment and hardware to reach that goal. He also served as director during a pivotal moment for the agency: the loss of STS-107 and the crew of space shuttle Columbia. He made it his personal responsibility to meet with the families, look after them, and attend memorial services, all while keeping the families informed of the accident investigation as it unfolded.
“Gen. Howell led NASA Johnson through one of the most difficult chapters in our history, following the loss of Columbia and her crew,” said acting associate administrator Vanessa Wyche. “He brought strength and steady direction, guiding the workforce with clarity and compassion. He cared deeply for the people behind the mission and shared his leadership skills generously with the team. We extend our heartfelt condolences to his family and all who knew and loved him.”
At the time of his selection as director, he was serving as senior vice president with Science Applications International Corporation (SAIC) as the program manager for the safety, reliability, and quality assurance contract at Johnson. Following the accident, he made it his mission to improve the relationship between the civil servant and contractor workforce. He left his position and the agency, in October 2005, shortly after the Return-to-Flight mission of STS-114.
“General Howell stepped into leadership at Johnson during a pivotal time, as the International Space Station was just beginning to take shape. He led and supported NASA’s successes not only in space but here on the ground — helping to strengthen the center’s culture and offering guidance through both triumph and tragedy,” said Steve Koerner, Johnson Space Center’s acting director. “On behalf of NASA’s Johnson Space Center, we offer our deepest sympathies to his family, friends, and all those who had the privilege of working alongside him. The impact of his legacy will continue to shape Johnson for decades to come.”
The Victoria, Texas, native was a retired lieutenant general in the U.S. Marine Corps with a decorated military career prior to his service at NASA. He flew more than 300 combat missions in Vietnam and Thailand.
Howell is survived by his wife Janel and two children. A tree dedication will be held at NASA Johnson’s memorial grove in the coming year.

NASA Mission Monitoring Air Quality from Space Extended
4 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater)Since launching in 2023, NASA’s Tropospheric Emissions: Monitoring of Pollution mission, or TEMPO, has been measuring the quality of the air we breathe from 22,000 miles above the ground. June 19 marked the successful completion of TEMPO’s 20-month-long initial prime mission, and based on the quality of measurements to date, the mission has been extended through at least September 2026. The TEMPO mission is NASA’s first to use a spectrometer to gather hourly air quality data continuously over North America during daytime hours. It can see details down to just a few square miles, a significant advancement over previous satellites.
“NASA satellites have a long history of missions lasting well beyond the primary mission timeline. While TEMPO has completed its primary mission, the life for TEMPO is far from over,” said Laura Judd, research physical scientist and TEMPO science team member at NASA’s Langley Research Center in Hampton, Virginia. “It is a big jump going from once-daily images prior to this mission to hourly data. We are continually learning how to use this data to interpret how emissions change over time and how to track anomalous events, such as smoggy days in cities or the transport of wildfire smoke.”

By measuring nitrogen dioxide (NO2) and formaldehyde (HCHO), TEMPO can derive the presence of near-surface ozone. On Aug. 2, 2024 over Houston, TEMPO observed exceptionally high ozone levels in the area. On the left, NO2 builds up in the atmosphere over the city and over the Houston Ship Channel. On the right, formaldehyde levels are seen reaching a peak in the early afternoon. Formaldehyde is largely formed through the oxidation of hydrocarbons, an ingredient of ozone production, such as those that can be emitted by petrochemical facilities found in the Houston Ship Channel. Trent Schindler/NASA's Scientific Visualization StudioWhen air quality is altered by smog, wildfire smoke, dust, or emissions from vehicle traffic and power plants, TEMPO detects the trace gases that come with those effects. These include nitrogen dioxide, ozone, and formaldehyde in the troposphere, the lowest layer of Earth’s atmosphere.
“A major breakthrough during the primary mission has been the successful test of data delivery in under three hours with the help of NASA’s Satellite Needs Working Group. This information empowers decision-makers and first responders to issue timely air quality warnings and help the public reduce outdoor exposure during times of higher pollution,” said Hazem Mahmoud, lead data scientist at NASA’s Atmospheric Science Data Center located at Langley Research Center.

TEMPO data is archived and distributed freely through the Atmospheric Science Data Center. “The TEMPO mission has set a groundbreaking record as the first mission to surpass two petabytes, or 2 million gigabytes, of data downloads within a single year,” said Mahmoud. “With over 800 unique users, the substantial demand for TEMPO’s data underscores its critical role and the immense value it provides to the scientific community and beyond.” Air quality forecasters, atmospheric scientists, and health researchers make up the bulk of the data users so far.

On April 14, strong winds triggered the formation of a huge dust storm in the U.S. central plains and fueled the ignition of grassland fires in Oklahoma. On the left, the NO2 plumes originating from the grassland fires are tracked hour-by-hour by TEMPO. Smoke can be discerned from dust as a source since dust is not a source of NO2. The animation on the right shows the ultraviolet (UV) aerosol index, which indicates particulates in the atmosphere that absorb UV light, such as dust and smoke. Trent Schindler/NASA's Scientific Visualization StudioThe TEMPO mission is a collaboration between NASA and the Smithsonian Astrophysical Observatory, whose Center for Astrophysics Harvard & Smithsonian oversees daily operations of the TEMPO instrument and produces data products through its Instrument Operations Center.
Datasets from TEMPO will be expanded through collaborations with partner agencies like the National Oceanic and Atmospheric Administration (NOAA), which is deriving aerosol products that can distinguish between smoke and dust particles and offer insights into their altitude and concentration.

On May 5, TEMPO measured NO2 emissions over the Twin Cities in the center of Minnesota during morning rush hour. The NO2 increases seen mid-day through the early evening hours are illustrated by the red and black shaded areas at the Red River Valley along the North Dakota state line. These levels are driven by emissions from the soils in agriculturally rich areas. Agricultural soil emissions are influenced by environmental factors like temperature and moisture as well as fertilizer application. Small fires and enhancements from mining activities can also be seen popping up across the region through the afternoon.Trent Schindler/NASA's Scientific Visualization Studio“These datasets are being used to inform the public of rush-hour pollution, air quality alerts, and the movement of smoke from forest fires,” said Xiong Liu, TEMPO’s principal investigator at the Center for Astrophysics Harvard & Smithsonian. “The library will soon grow with the important addition of aerosol products. Users will be able to use these expanded TEMPO products for air quality monitoring, improving forecast models, deriving pollutant amounts in emissions and many other science applications.”
The TEMPO mission detects and highlights movement of smoke originating from fires burning in Manitoba on June 2. Seen in purple hues are observations made by TEMPO in the ultraviolet spectrum compared to Advanced Baseline Imagers (ABIs) on NOAA’s GOES-R series of weather satellites that do not have the needed spectral coverage. The NOAA GOES-R data paired with NASA’s TEMPO data enhance state and local agencies’ ability to provide near-real-time smoke and dust impacts in local air quality forecasts.NOAA/NESDIS/Center for Satellite Applications and Research
“The TEMPO data validation has truly been a community effort with over 20 agencies at the federal and international level, as well as a community of over 200 scientists at research and academic institutions,” Judd added. “I look forward to seeing how TEMPO data will help close knowledge gaps about the timing, sources, and evolution of air pollution from this unprecedented space-based view.”
An agency review will take place in the fall to assess TEMPO’s achievements and extended mission goals and identify lessons learned that can be applied to future missions.
The TEMPO mission is part of NASA’s Earth Venture Instrument program, which includes small, targeted science investigations designed to complement NASA’s larger research missions. The instrument also forms part of a virtual constellation of air quality monitors for the Northern Hemisphere which includes South Korea’s Geostationary Environment Monitoring Spectrometer and ESA’s (European Space Agency) Sentinel-4 satellite. TEMPO was built by BAE Systems Inc., Space & Mission Systems (formerly Ball Aerospace). It flies onboard the Intelsat 40e satellite built by Maxar Technologies. The TEMPO Instrument Operations Center and the Science Data Processing Center are operated by the Smithsonian Astrophysical Observatory, part of the Center for Astrophysics | Harvard & Smithsonian in Cambridge.

A previously unexplored globular cluster glitters with multicolored stars in this NASA Hubble Space Telescope image. Globular clusters like this one, called ESO 591-12 or Palomar 8, are spherical collections of tens of thousands to millions of stars tightly bound together by gravity. Globular clusters generally form early in the galaxies’ histories in regions rich in gas and dust. Since the stars form from the same cloud of gas as it collapses, they typically hover around the same age. Strewn across this image of ESO 591-12 are a number of red and blue stars. The colors indicate their temperatures; red stars are cooler, while the blue stars are hotter.
Hubble captured the data used to create this image of ESO 591-12 as part of a study intended to resolve individual stars of the entire globular cluster system of the Milky Way. Hubble revolutionized the study of globular clusters since earthbound telescopes are unable to distinguish individual stars in the compact clusters. The study is part of the Hubble Missing Globular Clusters Survey, which targets 34 confirmed Milky Way globular clusters that Hubble has yet to observe.
The program aims to provide complete observations of ages and distances for all of the Milky Way’s globular clusters and investigate fundamental properties of still-unexplored clusters in the galactic bulge or halo. The observations will provide key information on the early stages of our galaxy, when globular clusters formed.

Proof That Adult Brains Make New Neurons Settles Scientific Controversy
Adult brains grow new neurons, and scientists have finally pinpointed where they come from
In Situ Resource Utilization and the Importance of Lunar Ice for Artemis III
What is the importance of studying and utilizing lunar polar volatiles during the Artemis program, and specifically for first crewed mission, Artemis III? This is what a recent study presented at the Lunar and Planetary Science Conference hopes to address as an international team of researchers investigated using lunar polar volatiles for in situ resource utilization (ISRU) purposes. In geology, volatiles are substances that vaporize at low temperatures, and examples include water, carbon dioxide, and sulfur dioxide. In the case of the Moon, key volatiles are water located in permanently shadowed regions (PSRs) at the lunar south polar region.
