Hi, new here.
I'm wondering if any news has come down about finalizing what MSL will run on? Will it be 2 Boeing's MMRTG (at ~100 watts?) or Lockheed Martin’s SRG (again ~100watts?), have they decided yet? Willl MSL use the RPS to trickle charge a battery or will MSL run on the RPS only? God I hope solar is not a option is anyone pushing for it? |

The cooling loop (heat rejection subsystem or HRS) on the rover is very similar to the one on the cruise stage that runs around the cruise stage and down into the rover. This is based on the same design we first used on Mars Pathfinder then MER for the cruise HRS. Same dual redundant pumps on all of these loops.
I really love them. Essentially they maintain the rover body near room temperature most of the time taken from heat from the hot MMRTG that would otherwise radiate out to the Mars environment. As Paolo points out though, the rover freon only controls the temperature inside the rover but not its appendages. We need old fashioned electric heaters for that. -Rob |
