A Russian Progress resupply rocket had a failure and was lost.

This is the fourth such resupply failure and the second Progress failure. The other two were Antares with the 50 year old Russian engine and Falcon 9 CRS-7.

Weirdly on the bright side, if you're going to have a failure, these resupply missions are the place to have them happen. No lives have been lost and the ISS has enough supplies to overcome these failures. It was a little touch and go in 2015 though when the failures were back to back though.

"...According to an unconfirmed report on the online forum of the Novosti Kosmonavtiki magazine, at the time of the accident, the rocket's flight control system issued the so-called AVD command, which stands for the "Emergency Engine Cutoff." The AVD command was reportedly triggered during an interval between L+382.31 and 382.37 seconds by an unacceptable deviation of the vehicle from its prescribed trajectory, which was so severe that it had caused the rocket's gyroscopic control system to stall. Moreover, the cargo ship was apparently sheared off from the stage shortly thereafter in a violent breakup, followed by a some sort of impact between the two vehicles.


Overall, this account resembled the circumstances leading to the loss of the Progress M-27M spacecraft in April 2015..."
