The Aeolus satellite tv for pc was comparatively modest in dimension and mass—about 1.1 metric tons with its gas tank empty—however ESA hailed Friday’s “assisted re-entry” as proof that the house company takes the stewardship of house significantly.
When the Aeolus mission was conceived within the late 1990s, there have been no tips for European satellites concerning house particles or the protection of their re-entry.

Future ESA satellites will must be able to a focused re-entry, the place rocket engines steer the spacecraft towards a selected patch of ocean or are designed to deplete from aerodynamic heating.
