Instrument on GRACE-FO fails

The U.S/German science two-satellite constellation, launched in May, has not gathered any science data since July because one instrument on one satellite has shut down.

It appears the problem is related to an electrical problem. The article provides little information, though they say they will switch to a back up system later this month. I wonder why this has taken so long.

The article at the link calls this “a glitch.” That is a lie and bad journalism. Any failure that shuts down a spacecraft for months and requires the use of a back up is a major failure, not a mere “glitch.” I wish news organizations would stop using that word, as it only exists to help minimize the seriousness of a problem.

SpaceX gets an eighth Iridium launch

The competition heats up: SpaceX has won a new launch contract, this time by launching both Iridium’s five satellites as well as the NASA/German Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission.

Both NASA and Iridium will save money by sharing the ride, while SpaceX gets more business.
