Hubble Space Telescope and Swift Observatory Orbit Decay Study

The NESC conducted an independent study of the Hubble Space Telescope (HST) orbital decay to inform the timeline to reentry, loss of science and risk to the public for an uncontrolled reentry. The HST reentry and demise have been extensively studied and reported on by numerous organizations. A quick study was performed utilizing different tools and approaches from other studies to compare against current predictions. An additional quick look at the predicted reentry timeline for the Neil Gehrels Swift Observatory was included.
