## Landing a Rover

Landing on Mars is challenging because there’s is too much atmosphere to be ignored, but too little to cushion the landing. Hence, all Mars rovers will have a three phrases: Entry, Descent and Landing (abbrieviated EDL). (Lakdawalla, n.d.)

## How the Curiosity Rover worked

• Lots of redundancy. A-side and B-side electronics.
• The battery was a MMRTG battery. Curiosity used plutonium-238 as the nuclear fuel, and an array of thermocouples reliably converted the released heat into electricity with no moving parts.

Things to account for:

• Operating temperatures of each component. Scientists maintained a heating table, and also had schedules to ensure that the various parts were heated to operating temperature before functioning.
• Have a system collecting heat output from energy
