Debris from DART could hit Earth and Mars within a decade, say scientists

On Sept. 26th, 2022, NASA's Double Asteroids Redirect Test (DART) collided with Dimorphos, the small moonlet orbiting the larger asteroid Didymos. In so doing, the mission successfully demonstrated a proposed strategy for ...

Lessons from industry can inform satellite and spacecraft management in orbit

Most space mission systems historically have used one spacecraft designed to complete an entire mission independently. Whether it was a weather satellite or a human-crewed module like Apollo, nearly every spacecraft was deployed ...

The evolution of the Trappist-1 planetary system

Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around them, such as asteroids ...

A European lander could return an ice core for a fraction of the cost of Europa Clipper

Cost is a major driving factor in the development of space exploration missions. Any new technology or trick that could lower the cost of a mission makes it much more appealing for mission planners. Therefore, much of NASA's ...
