NASA’s Artemis II Lunar Science Operations to Inform Future Missions

While the Artemis II crew will be the first humans to test NASA’s Orion spacecraft in space, they will also conduct science investigations that will inform future deep space missions, including a lunar science investigation as Orion flies about 4,000 to 6,000 miles from the Moon’s surface.

Close-Up Views of NASA’s DART Impact to Inform Planetary Defense

On Sept. 11, 2022, engineers at a flight control center in Turin, Italy, sent a radio signal into deep space. Its destination was NASA’s DART (Double Asteroid Redirection Test) spacecraft flying toward an asteroid more than 5 million miles away. The message prompted the spacecraft to execute a series of pre-programmed commands that caused a small, […]

NASA’s Apollo Samples, LRO Help Scientists Predict Moonquakes

Moonquakes pose little risk to astronauts during a mission lasting just a few days. But their effects on longer-term lunar surface assets could be significant.

NASA Tests New Heat Source Fuel for Deep Space Exploration

To explore the unknown in deep space, millions of miles away from Earth, it’s crucial for spacecraft to have ample power. NASA’s radioisotope power systems (RPS) are a viable option for these missions and have been used for over 60 years, including for the agency’s Voyager spacecraft and Perseverance Mars rover. These nuclear batteries provide […]

Near-Earth Asteroids as of September 2025

Each month, NASA’s Planetary Defense Coordination Office releases a monthly update featuring the most recent figures on NASA’s planetary defense efforts, near-Earth object close approaches, and other timely facts about comets and asteroids that could pose an impact hazard with Earth. Here is what we’ve found so far. Updated: September 11, 2025

Mission Accomplished! Artemis ROADS III National Challenge Competitors Celebrate their Achievements

The NASA Science Activation program’s Northwest Earth and Space Sciences Pathways (NESSP) team has successfully concluded the 2024–2025 Artemis ROADS III National Challenge, an educational competition that brought real NASA mission objectives to student teams (and reached more than 1,500 learners) across the country. From December 2024 through May 2025, over 300 teams of upper […]

NASA Interns Conduct Aerospace Research in Microgravity

The NASA Science Activation program’s STEM (Science, Technology, Engineering, and Mathematics) Enhancement in Earth Science (SEES) Summer Intern Program, hosted by the University of Texas Center for Space Research, continues to expand opportunities for high school students to engage in authentic spaceflight research. As part of the SEES Microgravity Research initiative, four interns were selected […]

Percolating Clues: NASA Models New Way to Build Planetary Cores

A new NASA study reveals a surprising way planetary cores may have formed—one that could reshape how scientists understand the early evolution of rocky planets like Mars. Conducted by a team of early-career scientists and long-time researchers across the Astromaterials Research and Exploration Science (ARES) Division at NASA’s Johnson Space Center in Houston, the study […]

NASA’s Dragonfly Mission Sets Sights on Titan’s Mysteries

When it descends through the thick golden haze on Saturn’s moon Titan, NASA’s Dragonfly rotorcraft will find eerily familiar terrain. Dunes wrap around Titan’s equator. Clouds drift across its skies. Rain drizzles. Rivers flow, forming canyons, lakes and seas.  But not everything is as familiar as it seems. At minus 292 degrees Fahrenheit, the dune […]
