“A planet-encircling dust storm on Mars, which was first detected May 30 and halted operations for the Opportunity rover, continues to abate. With clearing skies over Opportunity’s resting spot in Mars’ Perseverance Valley, engineers at NASA’s Jet Propulsion …

“In the darkest and coldest parts of its polar regions, a team of scientists has directly observed definitive evidence of water ice on the Moon’s surface. These ice deposits are patchily distributed and could possibly be ancient. At the …

“NASA’s Opportunity rover has been silent since June 10, when a planet-encircling dust storm cut off solar power for the nearly-15-year-old rover. Now that scientists think the global dust storm is “decaying” — meaning more dust is falling out of …

“Teams preparing for launch of NASA’s Parker Solar Probe are beginning a busy week leading up to liftoff, scheduled for Saturday, Aug. 11, at 3:33 a.m. EDT, the opening of a 65-minute window. The spacecraft will launch …

“The International Space Station is officially home to the coolest experiment in space. NASA’s Cold Atom Laboratory (CAL) was installed in the station’s U.S. science lab in late May and is now producing clouds of ultracold atoms …

“For the first time ever, scientists using NASA’s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This neutrino traveled 3.7 billion years at almost the speed of light before being …

“NASA’s Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current life on …

“Ever since NASA’s Voyager 1 spacecraft flew past Jupiter in March, 1979, scientists have wondered about the origin of Jupiter’s lightning. That encounter confirmed the existence of Jovian lightning, which had been theorized for centuries. But when the …

“NASA’s Dawn spacecraft is maneuvering to its lowest-ever orbit for a close-up examination of the inner solar system’s only dwarf planet. In early June, Dawn will reach its new, final orbit above Ceres. Soon after, it will begin …

“Twin satellites that will monitor Earth’s water cycle are scheduled to launch from Vandenberg Air Force Base in Central California on Tuesday, May 22, in a unique rideshare arrangement. The two Gravity Recovery and Climate Experiment Follow-On mission (GRACE …
