AGU 2012[edit]

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)

Power source[edit]

The tune is changing, now the Aviation Week is talking of using solar panels:[1]). 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: (talk) 14:18, 16 July 2013 (UTC)

RFIs starting to go out[edit]

The first rover RFI went out last Friday. [2] 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)

Unintentionally removed { {Portal|Astrobiology}}[edit]

Seems I may have unintentionally rm the { {Portal|Astrobiology}} as a dup - *entirely* ok w/ me if you would like to rv or related - enjoy! :) Drbogdan (talk) 17:24, 10 July 2013 (UTC)

I am glad you removed the duplicated portal, even if by mistake. Thanks! BatteryIncluded (talk) 17:32, 10 July 2013 (UTC)

Launch table - wrong units[edit]

The table shows figures from the source eg 7.7 to 11.1 for 2018 launch. However source says this is launch energy and is in units of km^2/s^2 so it isn't Launch velocity in km/s. I have changed table to show energy and km^2/s^2 units. Not sure if this should show C3-launch energy. Also not sure if this is a meaningful measure that should be included - does it really take that much more energy launch in 2020 rather than 2018? There is also VHP – V∞ (km/sec) which is less for 2020 than for 2018 not sure if that is more meaningful or needed in addition to understand. crandles (talk) 18:21, 29 April 2016 (UTC)

I'm unaware of specific launch energies involved, but I would assume that the 2018 window (which for people reading this in the future is soon and the rover most certainly will not be ready) will cost more, as you stated, because of a not-so-nice alignment of Earth's and Mars's orbital planes. In astrodynamics, plane-change maneuvers are expensive fuel-wise. Madmohawk (talk) 14:30, 26 April 2017 (UTC)

Landing sites[edit]

FYI, landing site selection presentations are freely available here. This could be an interesting section in the article. There are three landing sites remaining: Jezero Crater, Northeast Syrtis, and Columbia Hills (yes, where Spirit died). Actually, the scientific justification for Columbia Hills is absolutely fascinating. — Preceding unsigned comment added by (talk) 16:28, 31 August 2017 (UTC)
