NASA has made progress with plans to boost the rapidly decaying orbit of the Swift observatory while calling an abrupt halt to an attempt to reboost the International Space Station (ISS) using SpaceX's Dragon.
Following a successful demonstration on September 3, NASA and SpaceX were trying for a 19-minute, 22-second burn using the Draco thrusters located in the trunk of SpaceX's CRS-33 Dragon cargo spacecraft. However, at three minutes and 45 seconds, controllers saw something they didn't like and commanded a manual abort .
