“The booster rocket with the Briz-M accelerator unit is to put a Luch relay satellite in orbit,” the Roskosmos told ITAR-TASS detailing the upcoming launch of the Proton technology rocket which has remained grounded since May 16.
On Tuesday, Khrunichev Space Center specialists were installing screen vacuum insulation on Briz-M which is to put the satellite in parking orbit. Simultaneously, efforts were underway at launch pad # 81 to prepare the ground-handling equipment.
The Proton-M boost carrying the Express-AM4P communication satellite burnt in dense layers of the atmosphere on May 16. The experts investigating the accident said it was caused by disintegration of a bearing assembly in the turbo pump of the third-stage engine.
