According to the RIA Novosti news publication, the take-off of a heavy rocket with the name Delta IV Heavy, to which the American military satellite is attached, was canceled in California. This was reported by the launch operator seven seconds before the activation of the aircraft.
The reason for this outcome was a technical error that no one could have expected. At the moment, all the forces of the United Launch Alliance are aimed at correcting problems.
There is no information on when the mission of NROL-71 will continue, however, company representatives say that they will let know about it as soon as they answer this question.
The launch of the rocket, as is known, was carried out from the US Air Force Vanderberg complex, which is located in California.
It was also reported that the pumping of cryogenic fuel has already begun.
