Are you illiterate? I literally wrote out exactly what they would use. MAV. Mars ascent vehicle. It's a beefed up sounding rocket. They literally have started on these "vehicles". I work with people who currently are doing trajectory analysis for MAV. Of course I mentioned two spacex vehicles. They would be great for sending the orbiter and even the lander/MAV. Maybe learn what you're talking about before just saying shit? Especially since NASA is currently operating more vehicles on Mars than anyone else and has extensive knowledge on landing and orbiting it.

As for the astronomy jab, I repeat they have more vehicles operating on Mars than anyone else. They have satellites around Jupiter. They're about to send a flying laboratory to Titan. They operate the international space station. They do a bit more than astronomy you dolt.
