At the launch of the carrier rocket Falcon 9 on 11 may, SpaceX tested the new upper stage Block 5. After delivery to orbit, it successfully landed on a platform in the Atlantic ocean.
It is planned that the Block 5 will be used repeatedly. According to the statements of the head of SpaceX Elon musk, the first stage will survive for at least ten runs without maintenance: «it is only necessary to attach the top tier, set on the launch pad, fill and run». Theoretically, the resource Block 5 may be 100 spins.
SpaceX aims to reduce the time required to prepare for the launch. Next year the company plans to send the same media twice within 24 hours. All this in order to reduce the cost of launch: now, a single launch of the Falcon 9 costs $ 50 million.
May 11, Falcon 9 delivered into orbit Bangladeshi Bangabandhu telecommunications satellite from Cape Canaveral, Florida. The unit is designed to provide broadcasting in rural Bangladesh and the surrounding areas. The launch was to take place the day before, but canceled the automatic one minute before the start.
