On mars? Want a couple of pints of water?
Dig up a cubic foot of mars dirt and you will be good to go! (assuming you have spent the past several years building up an immunity to iocane Perchlorate)

Opportunity's total odometry as of November 5, 2013 (sol 3478) is 23.94 miles (38.53 km).
Lunokhod 2 operated for about 4 months, covered 42 km (26 miles) of terrain
322 Earth days of operations, Lunokhod 1 traveled 10.5 km

Is it easier to drive on the moon than Mars? I would imagine so.
But it's more complicated than that. I think that the site selection would favor "interesting" places, although Mars may have plenty of flat planes.
That's a recent satellite image enhanced to show the tracks of the rover. 1/21/2014 9:13:47 PM |

Is your conversion from humans to Kerbals really 3-to-5? Sure, on a size basis, that might work. But I've heard the Kerbin regulators are a little more lax on margin requirements.2/9/2014 4:15:07 PM |

This is a super cool graph
http://www.nasaspaceflight.com/2014/03/nasa-asteroid-capture-mission-definitions/
This displays the maximum asteroid mass we can transport, given the mission length and launch vehicle. Really changes your perspective about space. You can move very large things at low cost if you're willing to take a long time to do it.
I think it sounds like a really worthwhile mission. It is validly new, and it actually has potential for an economic return via asteroid mining (however unlikely). But getting the rock off the surface of Itokawa is a bit of a buzz kill. We already have asteroid material. The scientific value of this will be to obtain a low density asteroid that carries information about how it spent the last billion years. If the asteroid spent the last billion years sitting on the surface of Itokawa, then it's not perfectly representative of what we want.
Also, this thing is going to have something like a ton of propellant. Considering this is an ion drive, might that make it the highest impulse engine ever? 4/2/2014 8:21:44 AM |

There is a more definite plan for scheduling that was just determined. They just told us about it on Monday actually. I'm not allowed to talk about it though so who knows when they'll release it to the public, they may change it some more.
Interesting thing about the asteroid retrieval -- they had a brainstorming here meeting about a year ago that was open to all NASA folks. They had a few asteroids they were looking at but since then they discovered that these asteroids, although fairly large in mass, were not dense at all. They were composed of loosely held together dust, giving them the consistency of a like a dust bunny you'd find under the bed. 4/2/2014 3:01:51 PM |

Dear Colleagues,
Given Russia's ongoing violation of Ukraine's sovereignty and territorial integrity, until further notice, the U.S. Government has determined that all NASA contacts with Russian Government representatives are suspended, unless the activity has been specifically excepted. This suspension includes NASA travel to Russia and visits by Russian Government representatives to NASA facilities, bilateral meetings, email, and teleconferences or videoconferences. At the present time, only operational International Space Station activities have been excepted. In addition, multilateral meetings held outside of Russia that may include Russian participation are not precluded under the present guidance. If desired, our office will assist in communication with Russian entities regarding this suspension of activities. Specific questions regarding the implementation of this guidance can be directed to Ms. Meredith McKay, 202.358.1240 or meredith.mckay@nasa.gov, in our office.
We remain in close contact with the Department of State and other U.S. Government departments and agencies. If the situation changes, further guidance will be disseminated.

hmm... that's interesting.
The most common type are the carbonaceous chondrite, which is worth studying because they don't make it through our atmosphere with their structure in tact. But those tend to cluster around specific gravities of 1 - 2. There are even large asteroids, like Mathilde at 1.3, with low densities.
What you're talking about is validly new to science. For the class of ~5 m asteroids, we can't hope to discover (much less profile) any except a small few very close to Earth. If they have similar composition to the larger ones we do understand, then we would still be talking about specific gravities around unity.
Presumably all the NASA people know this, so it makes me wonder what kinds of compositions we're talking about. Maybe the average 5 m asteroid has a density of 0.1 g/cm3 or something.4/2/2014 5:51:11 PM |
