Dr. Sivan, Director, VSSCAs regards heavy-lift vehicles, we are in the process of discussion. It will be a TSTO vehicle whose first stage, like SpaceX’s, will be a five-engine semi-cryo cluster. This will have a modular structure. With one core semi-cryo stage, we can simply go on adding any number of strap-ons, and different payload requirements can be met. The second stage will be a cryo-stage. After the first stage is separated, it can be recovered in sea, like SpaceX has done.
