Studying and exploring Mars is an essential part on the road to putting man on the planet
The design makes it an outstanding high-mobility vehicle used for Mars exploration
Very low development, construction, and operation cost

At perigee, velocity = 10.25 km/s 1st burn, velocity increases by 1.159 km/s
v at end of transfer orbit to match Mars’ velocity 2nd burn, velocity increases by 2.65 km/s
v required to be captured by Mars’ gravity and enter circular orbit at an altitude of 500 km
3rd burn, velocity decreases by 1.373 km/s
For atmospheric entry: 4th burn, velocity decreases by 0.0958 km/s

parachute deploys to reorient spacecraft and takes away heat shield
Main parachute deploys from blunt end of shell and pulls it away
Parachute deploys from the aft end of aircraft and separates it from rest of capsule
Aircraft releases parachute and flies down to cruise altitude
