NASA has selected one small explorer mission concept to advance toward flight design and another for an extended period of concept development. NASA’s Science Mission Directorate Science Management Council selected CINEMA (Cross-scale Investigation of Earth’s Magnetotail and Aurora) to enter Phase B of development, which includes planning and design for flight and mission operations. The […]

NASA’s Parker Solar Probe Spies Solar Wind ‘U-Turn’
Images captured by NASA’s Parker Solar Probe as the spacecraft made its record-breaking closest approach to the Sun in December 2024 have now revealed new details about how solar magnetic fields responsible for space weather escape from the Sun — and how sometimes they don’t. Like a toddler, our Sun occasionally has disruptive outbursts. But […]

NASA Analysis Shows Sun’s Activity Ramping Up
It looked like the Sun was heading toward a historic lull in activity. That trend flipped in 2008, according to new research. The Sun has become increasingly active since 2008, a new NASA study shows. Solar activity is known to fluctuate in cycles of 11 years, but there are longer-term variations that can last decades. […]

NASA’s Artemis II Lunar Science Operations to Inform Future Missions
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: Ceres May Have Had Long-Standing Energy to Fuel Habitability
The dwarf planet is cold now, but new research paints a picture of Ceres hosting a deep, long-lived energy source that may have maintained habitable conditions in the past. New NASA research has found that Ceres may have had a lasting source of chemical energy: the right types of molecules needed to fuel some microbial […]
