As space becomes more accessible, the number of satellites being launched into orbit has increased substantially with little or no framework in place to regulate what happens to leftover debris or out-of-commission spacecrafts. The Earth's orbit, therefore, has grown increasingly congested. The SSR...

All rocket-engine burns occur at a precise moment and last for a precise amount of time so that the satellite achieves its proper position in space. In 1990 the United States began launching some satellites from aircraft flying at high altitudes. This method still requires a rocket-powered ...
