Marooned Off Vesta

mcgrew writes with this quote from an AP report: "After four years sailing through space, the Dawn spacecraft was expected to slip into orbit late Friday around a giant asteroid to begin a yearlong investigation into the origins of the solar system. It is the first of two scheduled tour stops for the NASA probe that almost never made it to the launch pad. Because of its stunted growth, Vesta holds 'a record of the earliest history of the solar system,' said the mission's lead scientist Christopher Russell of the University of California, Los Angeles." Dawn's mission homepage has all the information and pictures collected so far. On July 9th, it snapped our best look to date at the ~530-kilometer-wide Vesta, from 40,000 kilometers away. When it arrives, it will take observations from successively lower orbits, the final one being only 460km above Vesta's surface. Next May, Dawn will break orbit and head to Ceres. (mcgrew adds, "The submission's title is a nod to Isaac Asimov. Lets hope Dawn doesn't get marooned!")

    Why is it that an artist rendition done in the name of science is so poorly done? You get the impression that there are big chunks of rock floating every couple of miles/kilometeres in space. This is one reason why we can't get kids straight about science... and this is approved by the scientists!

  7. Interesting real estate for aliens by MetricT · · Score: 1

    I've often thought that if I were an alien intent on long-term observation of the solar system, I'd plant myself on either Vesta or (more likely) Ceres due to abundant construction material and (on Ceres) ice to crack to fuel, just enough gravity well to keep things from floating off, and just far enough away that you don't have to worry about the savages until they (hopefully) grow up.

    Yeah I know, it would be one of those one in a million sort of things, but a nerd can dream.

      Its funny because the same grooves are on other small bodies like the moons of Mars, however these grooves scale with the size of the asteroid. Its like objects like this have grooves on different scales so if you look very close you will still see grooves. I think they are likely caused by rolling rocks. In the light gravity rocks will bounce along the surface, touching down every revolution or so and leaving a crater in the soft surface.

    Get into a spacesuit, walk to the water tanks and shoot them with a raygun. That will give you enough trust to land on Vesta. Gravity there isn't strong enough to crush a cookie. Here.

      Our Fair City is a really funny short silly story (fantasy more than sci-fi) lampooning political corruption. It's in his collection 6xH. Haven't read Stranger in decades, someone borrowed my copy and I never got it back. Heinlein was another of my all-time favorites, although I think I enjoyed his stuff a lot more when I was young. Asimov's still my favorite, but these days Pratchett's my 2nd favorite even though I'm not really into fantasy; the guy's books are hilarious.

  14. Credit where credit is due by mcgrew · · Score: 3, Interesting

    /. editors get a lot of flak (and I'm guilty myself sometimes), but I have to point out that the summary is far superior to what I submitted. Soulskill not only added relevant copy, but he also added all the links except the one to TFA. He did more work than I on it, and I'm pleased with what he did. Good job, sir!

    The nod to Asimov was for two reasons. First, I've been a rabid Asimov fan for half a century, and second, the Dawn spacecraft is man's first visit to Vesta, and Marooned off Vesta was Asimov's first published story.

    I see only 27 comments have been posted, and I hope the title isn't the reason for the lack of commentary, with people thinking it's some of my bad sci-fi.
