One Last mission For Deep Space 1

    Check out the monthly reports. They are quite fun to read, because they are written in a "layman" fashion. Especially the parts where they are putting together the "using science camera for navigation"-kludge. And rebooting a system half a solar system away and hoping it comes up again after an OS upgrade.

    It's kinda sad that all the public focus is on the Mars missions, when there's stuff like DS1, Galileo, and NEAR that just keep on going..

  2. Why fly downstream from the comet? by Mxyzptlk · · Score: 4, Interesting
    I was just wondering - why fly downstream from the comet and subjecting DS1 to the shower of particles, when you could approach it from upstream (put DS1 between the comet and the sun). The primary purpose is to get pictures of the nucleus, not the coma, right? So - let DS1 slowly drift towards the nucleus, and steer it by looking at the whole of the coma and centering on it (we know the nucleus is in the middle, because we've placed DS1 approximately in the middle between the sun and the coma). This allows as much time and small adjustments (saving fuel) as possible, getting DS1 as close to the nucleus as possible.

    When this is done, continue past the nucleus into the comp and try to get a closeup picture or two of the coma before being blown to smithereens by the particles.
