The main PW-Sat 2 payload will be deorbitation system, which allows faster removal of satellites from their orbit after it completes its mission.
Deorbitation of satellites is now increasingly hot topic because of still grownig amount of “space debris” in orbit. These so-called space junk includes spent rocket stages, old satellites, and small fragments from the collision of satellites (such as the one in February 10, 2009, when there was a collision between functioning satellite Iridium 33 and inactive satellite Kosmos 2251). As a result of such event a lot of small parts are deployed into space, which are a great threat for operating spacecrafts. Adapting this kind of deorbitation systems into all the spacecrafts would prevent such unfortunate events.
