WASHINGTON — Lockheed Martin is redesigning the bus used for Global Positioning System satellites so they can be upgraded with new hardware on orbit, a company executive said Feb. 25.
Eric Brown, senior director of military space mission strategy at Lockheed Martin, said this is significant because the thinking today is that “once something was on orbit you were done with it.

The giant canopy that helped land Perseverance on Mars was tested here on Earth at NASA's Wallops Flight Facility in Virginia.
Test. Test again. Test again.
Testing spacecraft components prior to flight is vital for a successful mission.
Rarely do you get a do-over with a spacecraft after it launches, especially those bound for another planet. You need to do everything possible

Litter is not only a problem on Earth. According to NASA, there are currently millions of pieces of space junk in the range of altitudes from 200 to 2,000 kilometers above the Earth's surface, which is known as low Earth orbit (LEO). Most of the junk is comprised of objects created by humans, like pieces of old spacecraft or defunct satellites. This space debris can reach speeds of up to 18,000
