The Electron rocket on Saturday failed to launch two Earth remote sensing satellites of the American company BlackSky into orbit, Interfax reported.

According to the source, the abnormal situation occurred after the second stage engines were started, said the developer of the launch vehicle, Rocket Lab. 

During today's launch, there was a problem that led to the failure of the mission. The problem arose shortly after the launch of the second stage, the company said.

Mini-satellites weighing about 60 kg were supposed to be part of the orbital constellation, which allow obtaining optical images with a resolution of 90 cm from an altitude of 420 km.
