In 2022, NASA slammed a spacecraft into the asteroid Dimorphos and changed its orbit — the first time humanity had ever deflected a space rock. Now ESA's Hera mission is heading there to examine the aftermath. Here's how far planetary defense has come.
Tucked into an orbit that is neither the lunar surface nor Earth's backyard, Gateway is one of the stranger ideas in the Artemis program. Why build a small station out there at all? Here's a plain-language look at the NRHO, how Gateway differs from the ISS, and why it matters for reaching Mars.
