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? |

According to http://trs-new.jpl.nasa.gov/dspace/bitstre...6/1/05-0708.pdf MSL will use an MMRTG. I would think that the use of batteries is inevitable, as there's no way the avionics can run directly from RTG output, much less the payload. I'm sure they've done a detailed trade study of alternative RTGs, but I haven't seen those. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

I did not consider this but because the MMRTG puts out 2000w of heat they need a rather large radiator for the cruise stage, the SRG only puts out 500w. |
