Aging already
editThe MSL was originally scheduled for launch in 2009. Perhaps the plutonium dioxide for the 8 GPHS that will be used in each MMRTG has already been made and output is already reducing. Anyone know when the GPHS (to be used) were made ? Rod57 (talk) 14:45, 20 March 2010 (UTC)
Ownership
editWhile the MMRTGs were initially supplied by Boeing when the program started, they are now supplied by Pratt & Whitney (owned by United Technologies Corporation) due to the sale of the Canoga Park, Ca facility in 2005.
How many watts per MMRTG?
editThis page gives two different values for watts/MMRTG: 2kW, and 125W. What's up? -- 66.31.56.15 (talk) 19:49, 11 October 2011 (UTC)
- Electrical Watts and Heat Watts. Two different Watts. --Divega (talk) 08:57, 14 August 2012 (UTC)
How many volts per MMRTG?
editIs there any way to find out how many volts are in those batteries? Presario2200 (talk) 17:28, 4 April 2020 (UTC)
What other missions
editAre any other missions planned to use the MMRTG ? - Rod57 (talk) 13:40, 26 October 2012 (UTC)
- Looks like nothing is planned after the Mars 2020 rover. BatteryIncluded (talk) 06:56, 14 March 2015 (UTC)
- There are several proposals in the wings for future Discovery-Class missions -- 65.94.43.89 (talk) 06:17, 15 March 2015 (UTC)
- Yes, there are proposals, not plans. In my opinion, NASA will eventually assign and use the 2 surplus MMRTGs because their radioactivity is continuously decaying and is being wasted. BatteryIncluded (talk) 18:27, 15 March 2015 (UTC)

Multi Mission in the name
editArticle should probably emphasize in intro the significance of 'multi mission' in MMRTG, which is due the fact that it can "can operate both in atmospheres and in vacuum"[1] Ohsin (talk) 03:10, 14 March 2017 (UTC)

Could try to clarify : Why develop MMRTG rather than use previous design
editCan we add to this article to explain : Why did NASA develop MMRTG rather than use previous design ? Was it not possible to build/buy more of the old ones, or does the MMRTG have different requirements ? - Rod57 (talk) 13:10, 16 November 2021 (UTC)
