BALLISTIC SUPPORT MET-NET
The general scheme of the flight to the Mars consists of the following phases:- Placing the Spacecraft and MSS onto low orbit;- Speedup on the near-Earth orbit;- Transfer from the Earth to the Mars;- Jettison of SMS and injection of transfer module onto 2- or 3-day orbit around the Mars;- Operations of the transfer module on the ASM orbit as a satellite-retransmitter;
