Why Is Space Debris A Problem?

Why Is Space Debris A Problem? Human activities leave too many dead satellites and fragments of machinery discarded in Earth orbit. If left unchecked, space junk could pose significant problems for future generations — rendering access to space increasingly difficult, or at worst, impossible. What is space debris and why is it a problem? All

Was The ISS Successful?

Was The ISS Successful? The International Space Station (ISS) Program’s greatest accomplishment is as much a human achievement as it is a technological one—how best to plan, coordinate, and monitor the varied activities of the Program’s many organizations.

How Can Space Probe Travel Without Getting Hit?

How Can Space Probe Travel Without Getting Hit? The aerodynamic drag on small satellites in Low Earth orbit can be used to change orbits slightly to avoid debris collisions by changing the surface area exposed to atmospheric drag, alternating between low-drag and high-drag configurations to control deceleration. How do space probes keep moving? They use
