Space Debris

Space debris removal is not just an environmental concern. It makes money for all parties involved. Today’s digital infrastructure is being built in low Earth orbit. Satellite constellations from companies like SpaceX, OneWeb, Telesat, AST Space Mobile and many others are rapidly deploying to provide everything from internet to cell…

by Sandra Erwin — July 27, 2021 The main cause of in-orbit explosions is related to residual fuel that remains in tanks or fuel lines once a rocket stage or satellite is discarded in Earth orbit.

The Oort cloud represents the very edges of our solar system. The thinly dispersed collection of icy material starts roughly 200 times farther away from the sun than Pluto and stretches halfway to our sun’s nearest starry neighbor, Alpha Centauri. We know so little about it that its very existence…

This is a video simulating the burn-up of a Solar Array Drive Mechanism during atmospheric reentry using a plasma wind tunnel. This Solar Array Drive Mechanism (SADM) has the essential task of keeping a satellite's solar wings trained on the Sun, maintaining mission operations. But its bulky nature presents a…

(Image credit: NASA) Leading industrial nations have agreed to make the space junk problem a priority in order to ensure future sustainable use of space. The announcement, made at the G-7 Leaders' Summit in Cornwall, U.K., on…

70% of all cataloged objects are in low-Earth orbit (LEO), which extends to 2000 km above the Earth’s surface. To observe the Earth, spacecraft must orbit at such a low altitude. The spatial density of objects increases at high latitudes. Note: The debris field shown in the image is an…

A piece of orbital debris recently hit Canadarm2, the nearly 18-meter-long robotic arm on the International Space Station that helps with maintenance tasks and “catches” visiting spacecraft. Thankfully, the functioning of the robotic arm is unaffected.  According to Canadian Space Agency (CSA), a routine inspection on May 12 discovered the…
