What's Next for NASA's Artemis Program?
NASA is about to reveal the astronauts who will launch to space on the Artemis 3 mission. The announcement is scheduled for June 9, and speculation about the crew has been high since the return of the Artemis 2 mission in April. The Artemis program aims to return humans to the lunar surface by 2025 and establish a sustainable presence on the Moon.
Meteor Storms: A Threat to Future Moon Missions?
Meteor showers are a beautiful phenomenon, but could they harm NASA's future moon missions? NASA estimates that approximately 48.5 tons of naturally occurring space debris falls into Earth's atmosphere each day. During meteor showers, the space around Earth gets even more crowded, posing a potential threat to spacecraft.
A Star That Ate Its Planets?
A new study offers clues on the "chemical paradox" of a binary star system. The system, HD 81809, consists of two sun-like G stars with dramatically different chemical compositions. Astronomers suggest that one of the stars may have swallowed its own planets, which could explain the differences in metallicity.
