A NASA study using a series of supercomputer simulations reveals a potential new solution to a longstanding Martian mystery: How did Mars get its moons? The first step, the findings say, may have involved the destruction of an asteroid. The research team, led by Jacob Kegerreis, a postdoctoral research scientist at NASA’s Ames Research Center in California’s … Read more

With NASA’s Europa Clipper just weeks away from launch, five short videos give a behind-the-scenes peek at some of the engineers dedicated to making the mission a success. What does it take to build a massive spacecraft that will seek to determine if a mysterious moon has the right ingredients for life? Find out in … Read more
NASA’s Europa Clipper mission moves closer to launch as technicians worked on Wednesday, Sept. 11, inside the Payload Hazardous Servicing Facility to prepare the spacecraft for upcoming propellant loading at the agency’s Kennedy Space Center in Florida. The spacecraft will explore Jupiter’s icy moon Europa, which is considered one of the most promising habitable environments … Read more
The largest spacecraft NASA has ever built for planetary exploration just got its ‘wings’ — massive solar arrays to power it on the journey to Jupiter’s icy moon Europa. NASA’s Europa Clipper spacecraft recently got outfitted with a set of enormous solar arrays at the agency’s Kennedy Space Center in Florida. Each measuring about 46½ … Read more
As part of an asteroid sample exchange, NASA has transferred to JAXA (Japan Aerospace Exploration Agency) a portion of the asteroid Bennu sample collected by the agency’s OSIRIS-REx mission. The sample was officially handed over by NASA officials during a ceremony on Aug. 22 at JAXA’s Sagamihara, Japan, campus. This asteroid sample transfer follows the … Read more
Using cameras designed for navigation, scientists count ‘fireflies’ to determine the amount of radiation the spacecraft receives during each orbit of Jupiter. Scientists with NASA’s Juno mission have developed the first complete 3D radiation map of the Jupiter system. Along with characterizing the intensity of the high-energy particles near the orbit of the icy moon … Read more
The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is needed. A vein-filled rock is catching the eye of the science team of NASA’s Perseverance rover. Nicknamed “Cheyava Falls” by the team, the arrowhead-shaped rock contains fascinating traits that may … Read more
Early analysis of the asteroid Bennu sample returned by NASA’s OSIRIS-REx mission has revealed dust rich in carbon, nitrogen, and organic compounds, all of which are essential components for life as we know it. Dominated by clay minerals, particularly serpentine, the sample mirrors the type of rock found at mid-ocean ridges on Earth. The magnesium-sodium … Read more
NASA’s LRO (Lunar Reconnaissance Orbiter) imaged China’s Chang’e 6 sample return spacecraft on the far side of the Moon on June 7. Chang’e 6 landed on June 1, and when LRO passed over the landing site almost a week later, it acquired an image showing the lander on the rim of an eroded, 55-yard-diameter (about … Read more
