Aging already[edit]

The 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)[reply]

Ownership[edit]

While 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?[edit]

This 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)[reply]

Electrical Watts and Heat Watts. Two different Watts. --Divega (talk) 08:57, 14 August 2012 (UTC)[reply]

How many volts per MMRTG?[edit]

Is there any way to find out how many volts are in those batteries? Presario2200 (talk) 17:28, 4 April 2020 (UTC)[reply]

What other missions[edit]

Are any other missions planned to use the MMRTG ? - Rod57 (talk) 13:40, 26 October 2012 (UTC)[reply]

Looks like nothing is planned after the Mars 2020 rover. BatteryIncluded (talk) 06:56, 14 March 2015 (UTC)[reply]

There are several proposals in the wings for future Discovery-Class missions -- 65.94.43.89 (talk) 06:17, 15 March 2015 (UTC)[reply]

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)[reply]

Multi Mission in the name[edit]

Article 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)[reply]

Could try to clarify : Why develop MMRTG rather than use previous design[edit]

Can 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)[reply]
