Mars 2020 Rover
What is the spacecraft?
The spacecraft is the protective "spaceship" that enables the precious cargo (that is, the rover!) to travel between Earth and Mars. It is separate from the launch vehicle that carries the spacecraft and the rover outside of Earth's atmosphere and gravitational pull. The spacecraft includes the mechanical units that safely carry and maneuver the rover through the Martian atmosphere to a landing on Mars.
The three major parts of the Mars 2020 mission spacecraft design are based on the successful Mars Science Laboratory mission:
||Configuration for travel between Earth and Mars that includes an aeroshell (backshell with heat shield) in which the rover and its landing system are enclosed.
and Landing System:
|Configuration for entry into the Martian atmosphere. Includes the aeroshell, parachute, descent vehicle, and structure for a skycrane maneuver that will lower the rover to the Martian surface on tethers.
||A wheeled vehicle with science instruments for making discoveries on the Martian surface.
