NASA’s Carruthers Geocorona Observatory has captured its first images from space, revealing rare views of Earth and the Moon in ultraviolet light. Taken on Nov. 17 — still months before the mission’s science phase begins — these “first light” images confirm the spacecraft is healthy while hinting at the incredible views to come. The initial […]
Written by Michael Allen An international team of astronomers using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) has identified the origin of X-rays in a supermassive black hole’s jet, answering a question that has been unresolved since the earliest days of X-ray astronomy. Their findings are described in a paper published in The Astrophysical Journal Letters, […]
NASA is now accepting concepts for a new research challenge. The Opportunities in Research, Business, Innovation, and Technology (ORBIT) challenge is a multi-phase innovation competition designed to empower university and college students to develop next-generation solutions that benefit life on Earth and deep-space exploration. With up to $380,000 in total prize funding, NASA’s ORBIT challenges […]
After 25 years of continuous human presence in space, the International Space Station remains a training and proving ground for deep space missions, enabling NASA to focus on Artemis missions to the Moon and Mars. The orbiting laboratory is also a living archive of human experience, culture, and connection. Creating community With 290 visitors from […]
Volunteers participating in the Lake Observations by Citizen Scientists and Satellites (LOCSS) project have been collecting water level data in lakes since 2017. Now, the LOCSS team has used these data to examine the accuracy of water level measurements made from space.
With a second Trump Administration at the helm in 2025, NASA marked significant progress toward the Artemis II test flight early next year, which is the first crewed mission around the Moon in more than 50 years, as well as built upon its momentum toward a human return to the lunar surface in preparation to […]
The same historic facilities that some 50 years ago prepared NASA’s twin Voyager probes for their ongoing interstellar odyssey are helping to ready a towering commercial spacecraft for a journey to the Moon. Launches involve brutal shaking and astonishingly loud noises, and testing in these facilities mimics those conditions to help ensure mission hardware can […]
Clockwise from left, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui and NASA astronauts Jonny Kim, Zena Cardman, and Mike Fincke pose for a playful portrait through a circular opening in a hatch thermal cover aboard the International Space Station on Sept. 18, 2025. The cover provides micrometeoroid and orbital debris protection while maintaining cleanliness […]
Ensuring Astronaut Safety Achieving safe exploration of space in vehicles that rely upon closed environmental systems to recycle air and water to sustain life and are operated in extremely remote locations is a major challenge. The Toxicology and Environmental Chemistry (TEC) group at Johnson Space Center (JSC) is made up of 2 interrelated groups: Toxicology […]
Enabling Successful Research A major aim of biomedical research at NASA is to acquire data to evaluate, understand, and assess the biomedical hazards of spaceflight and to develop effective countermeasures. Data Science (S&DS) personnel provide statistical support to groups within the NASA JSC Human Health and Performance Directorate and other NASA communities. They have expertise […]
Mesas and dunes stand out in the view snapped by HiRISE, one of the imagers aboard the agency’s Mars Reconnaissance Orbiter. After nearly 20 years at the Red Planet, NASA’s Mars Reconnaissance Orbiter (MRO) has snapped its 100,000th image of the surface with its HiRISE camera. Short for High Resolution Imaging Science Experiment, HiRISE is […]
The NASA CalVal team spent 2025 improving their calibration techniques, strengthening collaboration, and sharing their work with the remote sensing community. Looking ahead, they’re applying lessons learned to prepare for future Landsat missions.
Microorganisms and Spaceflight Spaceflight poses a risk of adverse health effects due to the interactions between microorganisms, their hosts, and their environment. The JSC Microbiology team addresses the benefits and risks related to microorganisms, including infectious disease, allergens, environmental and food contamination, and the impacts of changes in environmental and human microbial ecology aboard spacecraft. […]
Does Spaceflight Alter the Human Immune System? Getting sick on Earth is nothing to sneeze at, but for astronauts on deep space exploration missions, the risk for contracting diseases may be elevated due to altered immunity. The Human Health and Performance Directorate’s Immunology/Virology Laboratory is ideally suited to study the effects of spaceflight on the […]
The JSC toxicologists establish guidelines for safe and acceptable levels of individual chemical contaminants in spacecraft air (SMACs) and drinking water (SWEGs) in collaboration with the National Research Council’s Committee on Toxicology (NRC COT) and through peer-reviewed publication. The framework for establishing these levels is documented for SMACs and SWEGs, and recent refinements to the Methods reflect current risk assessment […]
In 2025, the Harmonized Landsat and Sentinel-2 (HLS) program established itself as a cornerstone for global medium-resolution optical Earth observation and became one of NASA’s most downloaded products.
Scientists using NASA’s James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system, whose atmospheric composition challenges our understanding of how it formed. Officially named PSR J2322-2650b, this Jupiter-mass object appears to have an exotic helium-and-carbon-dominated atmosphere unlike any ever seen before. Soot clouds likely float through the […]
The NASA ORBIT (Opportunities in Research, Business, Innovation, and Technology for the Workforce) Challenge is a multi-phase, student-focused challenge designed to inspire and empower the next generation of innovators, engineers, entrepreneurs, and researchers. Compete for cash prizes, receive mentorship from NASA experts, and present your work at an in-person showcase. Finalists gain access to an […]
Launched in November, Sentinel-6B will track ocean height with ultraprecision to advance marine forecasting, national security, and more. Sentinel-6B, a joint mission by NASA and its U.S. and European partners to survey 90% of the world’s oceans for the benefit of communities and commerce, has started sending back its first measurements since launching in November. […]
