Launching in August 2022 and arriving at the asteroid belt in 2026, NASA’s Psyche spacecraft will orbit a world we can barely pinpoint from Earth…
Is there water on Mars? There sure is! It’s not exactly like water on Earth but Martian H20 can tell us a lot about the…
The planetary nature of a Mars-sized object orbiting extremely closely to an M-dwarf star has been validated using the Penn State Habitable-zone Planet Finder (HPF)….
In 2021, NASA completed its busiest year of development yet in low-Earth orbit, made history on Mars, continued to make progress on its Artemis plans…
At 7:50 pm EST, Webb’s first mid-course correction burn began. It lasted 65 minutes and is now complete. This burn is one of two milestones that are time critical — the first was the solar array…
Just two weeks after launching from Vandenberg Space Force Base in California, NASA’s Double Asteroid Redirection Test (DART) spacecraft has opened its “eye” and returned…
