Back in August 2011 whilst the MSL Spacecraft was being assembled at NASA’s Kennedy Space Center we were invited to visit the cleanroom to see the Curiosity Rover.
Unusually the MSL payload was being assembled inside the perimeter of the KSC property. This was because the Curiosity Rover has an atomic power supply, requiring security over and above the norm for a spacecraft.
The MSL spacecraft consists of a number of functional modules: The Cruise Stage, The Aeroshell (or Back Shell), The Heat Shield, The descent stage (known as the Sky Crane) and finally the Curiosity Rover.
We were able to see most of these modules as they were being prepared to be integrated into the spacecraft prior to being encased in the payload fairing for mating with the Atlas V booster.
Pictures from our cleanroom visit follow:
The MSL spacecraft was being assembled in what is called a cleanroom. In this case it is a rather large hanger. To gain access to the cleanroom everyone must don disposable protective clothing and ingress via an environmental control portal to prevent any contamination of the vehicle or its components.
As you can see from the pictures the Curiosity Rover was just about complete, but there was a lot of work left to do on the Sky Crane before final integration and transportation to the launch pad.

- Getting the Curiosity Rover safely to the surface of Mars is the goal of the MSL spacecraft. Once there Curiosity can start gathering data to return to scientists on Earth.
- The aeroshell protects the descent stage and the Curiosity Rover during the 8 month flight through space.

- The MSL Descent Stage is responsible for the final part of the landing. This will form the Sky Crane gently lowering the Curiosity Rover to the surface of MARS
- The landing radar is a critical part of the Sky Crane enabling the craft to determine exactly how high it is and the underlying terrain.
- The fuel lines and valves control the flow of propelant to the retro jets which guide and control the Sky Crane.
- The retro jets which control the descent of the MSL slowing the craft enough to safely land the Curiosity Rover on the surface of Mars.

- The Curiosity Rover has six wheels designed to traverse the boulder fields of the Martian landscape.
