NuSTAR Update

In anticipation of an upcoming launch, I recently provided anĀ overview of NASA’s next on-orbit telescope, NuSTAR. At that time, the launch date had not yet been set. A news release was issued today, postponing the launch:

The planned launch of NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) mission has been postponed after a March 15 launch status meeting. The launch will be rescheduled to allow additional time to confirm the flight software used by the launch vehicle’s flight computer will issue commands to the rocket as intended.

The time required to complete the software review has moved NuSTAR beyond the March timeframe currently available on the range at Kwajalein. In the interim, NASA will coordinate with the launch site to determine the earliest possible launch opportunity. This is expected to be within the next two months.

(emphasis mine)

At this point, I’m not entirely sure what might have caused the delay. While NASA is calling it a postponement, they had never officially announced the launch date — though it was implied that it would be in March. In any case, I’d much rather them spend a couple of extra months increasing their confidence in a flawless launch and operations than face the potential consequences of hasty action.
