NASA launches rescue mission to boost falling Swift space telescope back into orbit
By
Leah Crane
Summary
NASA's Neil Gehrels Swift Observatory space telescope is in orbital decay after nearly two decades in space, dropping from 600 km to 375 km altitude. A rescue mission launched on July 3 aims to boost the telescope back to a higher orbit, potentially extending its operational life for several more years. The mission is described as audacious, as satellite rescues of this nature are complex and risky.
