Images from the November 2023 flyby of asteroid Dinkinesh by NASA’s Lucy spacecraft show a trough on Dinkinesh where a large piece — about a quarter of the asteroid — suddenly shifted, a ridge, and a separate contact binary satellite (now known as Selam). Scientists say this complicated structure shows that Dinkinesh and Selam have … Read more
The spacecraft already is beyond the distance of Mars and is using ion propulsion to accelerate toward a metal-rich asteroid, where it will orbit and collect science data. NASA’s Psyche spacecraft passed its six-month checkup with a clean bill of health, and there’s no holding back now. Navigators are firing its futuristic-looking electric thrusters, which … Read more
Imagery from the solar-powered spacecraft shows some intriguing features on the ice-encased Jovian moon. Images from the JunoCam visible-light camera aboard NASA’s Juno spacecraft supports the theory that the icy crust at the north and south poles of Jupiter’s moon Europa is not where it used to be. Another high-resolution picture of the icy moon, … Read more
NASA’s Juno mission captured these views of Jupiter during its 59th close flyby of the giant planet on March 7, 2024. They provide a good look at Jupiter’s colorful belts and swirling storms, including the Great Red Spot. Close examination reveals something more: two glimpses of the tiny moon Amalthea (see Figure B below). Figure … Read more
The Sun will be at peak activity this year, providing a rare opportunity to study how solar storms and radiation could affect future astronauts on the Red Planet. In the months ahead, two of NASA’s Mars spacecraft will have an unprecedented opportunity to study how solar flares — giant explosions on the Sun’s surface — … Read more
This animation is an artist’s concept of Loki Patera, a lava lake on Jupiter’s moon Io, made using data from the JunoCam imager aboard NASA’s Juno spacecraft. With multiple islands in its interior, Loki is a depression filled with magma and rimmed with molten lava. Credit: NASA/JPL-Caltech/SwRI/MSSS Imagery from the solar-powered spacecraft provides close-ups of … Read more
The final downlink shift by the Ingenuity team was a time to reflect on a highly successful mission — and to prepare the first aircraft on another world for its new role. Engineers working on NASA’s Ingenuity Mars Helicopter assembled for one last time in a control room at the agency’s Jet Propulsion Laboratory in … Read more
As the Moon blotted out the Sun to viewers across the United States during the April 8 solar eclipse, NASA’s Lunar Reconnaissance Orbiter (LRO) captured an image from some 223,000 miles away of the highly anticipated celestial event. There are three cameras that comprise the LRO camera (LROC) suite: two Narrow Angle Cameras (NAC) and … Read more
Excitement is mounting as the largest spacecraft NASA has ever built for a planetary mission gets readied for an October launch. Engineers at NASA’s Jet Propulsion Laboratory in Southern California are running final tests and preparing the agency’s Europa Clipper spacecraft for the next leg of its journey: launching from NASA’s Kennedy Space Center in … Read more
NASA has selected the nine finalists of the Power to Explore Challenge, a national competition for K-12 students featuring the enabling power of radioisotopes. NASA selected nine finalists out of the 45 semifinalist student essays in the Power to Explore Challenge, a national competition for K-12 students featuring the enabling power of radioisotopes. Contestants were … Read more
