To Charlesb:

Thanks for fixing the reference links! I did not know they were broken in such a way. My fault.  :) --Marsbound2024 02:46, 19 December 2005 (UTC)

I've labelled the "six times the speed of a rifle bullet" statement with a fact tag. What's the speed of a rifle bullet? Which rifle, which bullet? Different rifles have muzzle velocities varying by a factor three (see, for example, [1]) so this needs to be more specific. 150.203.35.113 (talk) 09:15, 8 April 2009 (UTC)

That fact tag has been removed by now. But it's worse. Not everybody is familiar with rifle bullets. I'm not and I hope to keep it that way. So simply giving a velocity in kilometres per second and not mentioning bullets at all seems better. Stardust (spacecraft) suggests it's about 6 km/s, but I can't find a very specific number. Adding a vague tag. PiusImpavidus (talk) 14:04, 10 December 2015 (UTC)

As it happens, I handled it before seeing this. Yes, NASA use various standards of English for various audiences. Perhaps our earlier editor got a version made for rural Americans my age, most of whom would be less familiar than I am with tens of km/sec. Jim.henderson (talk) 00:00, 12 December 2015 (UTC)

Help needed on current plans for Mars sample return missions

The current situation of future plans for Mars sample return missions (such as Mars sample return mission, Mars Exploration Joint Initiative, Aurora programme, Mars-Grunt, Marco Polo (spacecraft) and MarcoPolo-R) needs to be updated, especially what current plans on contributions and time-tables are from NASA, ESA and Roskomos. If anybody can contribute with references, it would be most welcome. Tony Mach (talk) 09:07, 7 August 2012 (UTC)

use of the verb "return"

The transitive verb "return" means to bring BACK to a place of previous location. This is not what happens with pieces of asteroids. They have never been on earth before. This is a mistaken word-choice of astronomical proportions. Denicho (talk) 05:26, 8 December 2020 (UTC)

The sample may not be from Earth, but the ship or crew is, and they would return. But that's kind of a moot point anyway, it's the name those space missions get and that's it. Cambalachero (talk) 18:43, 1 April 2022 (UTC)
