So does this mean we just sit back & watch for 10 months? Or can something go wrong after this as well?
Main risk factor of this whole program was the injection into earth orbit with correct orientation. The journey to Mars should be relatively risk-free. There still will be minor corrections en-route to Mars by firing engines. Mainly, now we sit back and wait for it to be captured by Mars gravity, the next major step where failure can occur.
Can that be called a new achievement for the launch vehicle? Is it more difficult than a high orbit satellite?
