The Proton rocket, which has been grounded ever since a July 2 explosion just after launch, was scheduled to return to flight on September 17 carrying the SES satellite ASTRA 2E. But on September 12, the International Launch Services (ILS) which manages Proton’s commercial flights, announced a delay.

On September 11, Khrunichev engineers at the launch site received an out of tolerance reading in the first stage of the vehicle. It was determined that further investigation is necessary, requiring the launch vehicle be returned to the processing hall for additional testing. The vehicle and satellite remain in a safe configuration at the launch site.

ILS has not yet rescheduled the launch, but the problem is said to be routine.
