There were a lot of mixed feelings in the room after the NASA talk. The exact concept has to be known, especially the instruments before this will get a mission. The launch in 2018 is simply not to make when you want to stay within budget. NASA has to stretch the money to some years. This is not what NASA can afford not what NASA could do if there is plenty of money.--Stone (talk) 08:02, 6 December 2012 (UTC)
I agree. The mission's objective has not been determined, so the payload development, testing and incorporation could not be acomplished in such short notice. Any mention of a 2018 launch has to be treated as speculative. Cheers, BatteryIncluded (talk) 16:10, 6 December 2012 (UTC)
Grunsfeld ask for people who want to join the Science Definition Team. I do not know now how to get in, but I hope somebody I know will get onboard.--Stone (talk) 20:26, 8 December 2012 (UTC)
The tune is changing, now the Aviation Week is talking of using solar panels:). I will hold back any changes until we hear it from NASA. My assessment is that they will decide on the power source after selecting the scientific payload and defining the objectives. Cheers BatteryIncluded (talk) 22:01, 10 May 2013 (UTC)
My guess is that the author read this Wikipedia article and wrongly assumed the old rover concept art was for the 2020 rover. Marcus Qwertyus (talk) 19:41, 8 June 2013 (UTC)
Aviation Week is quite reliable on the latest scoop; it has been dubbed 'Aviation Leak', but NASA calls the shots. Still waiting for a press release on the mission. Cheers, BatteryIncluded (talk) 00:27, 9 June 2013 (UTC)
"Q: Will the Mars 2020 rover use the same type of nuclear power source that Curiosity uses?
A: No final decision on a power source for the 2020 rover would be made until the mission completes a review through the National Environmental Policy Act process, which considers the environmental impacts of launching and conducting the mission. This process is currently scheduled to conclude in late 2014. The baseline-design power source for 2020 mission planning is the same as Curiosity's: a multi-mission radioisotope thermoelectric generator. Other possible power sources are also under consideration, including solar power." Source: http://mars.nasa.gov/files/m2020/Mars2020FAQs.pdf. 22.214.171.124 (talk) 14:18, 16 July 2013 (UTC)
The first rover RFI went out last Friday.  Things are moving fast but I guess the RFP is still a long way off. I'm drafting a substantial re-write of this article in my userspace by the way. Marcus Qwertyus (talk) 09:08, 6 July 2013 (UTC)
