Galileo Nearing Its End

Anonymous Coward writes "Mission operations for the Galileo space probe, currently orbiting Jupiter, are scheduled to be shut down at the end of this month. Once a month thereafter scientists will check on the probe until September when the probe will be ordered to crash into Jupiter. The $1.5 billion mission met 70 percent of its science objectives and made a number of serendipitous discoveries along the way -- despite a range of problems."

      I doubt it has the fuel to escape Jupiter.

      They want to crash it so that it won't contaminate one of the moons by accidentally crashing there, possibly releasing earthly microbes.

      That possibility seems like a long shot to me. It also makes me a little sad to see a spacecraft crash, even intentionally, but that's just a sentimental spot I have.

      On the other hand, maybe the Jovian atmosphere will finally open the high gain antenna, if only for a moment. ;-)

      I hate the thought of crashing too.. I do have strong tendencies to develop emotional attachment to things.. even machines - especially ones that have done what this one has.

      Jupiter is a "gas giant".

      I wonder if it will ever find a solid surface to "land" on, or just sink deeper and deeper into ever higher compressed gases.

      Wasn't Voyager powered by a nuclear-powered thermopile generator? If so, what kind of chance is there that we may ignite Jupiter's compressed core (thermonuclearly speaking). If so, we may have another distant sun in a few months.

      It would seem to me that there are lower orbits the craft could be put into, where there would be no chance of a crash with the larger moons.

      On the other hand, such an orbit would probably soon decay anyway.

      Any speculation on whether the crash will yield any data that we didn't get from the probe sent into the atmosphere earlier?

      Cheap.

      $1.5B - three shuttle launches to put some ISS modules together. Of the three ISS crew members, 2.5 person-days are required to keep the thing up, leaving one guy able to spend four hours a day... doing very little science.

      $1.5B - plunk a probe into Jupiter's atmosphere, find out what's below the cloud tops, make multiple passes by every moon, and get pictures/magnetometer data of everything around Jupiter and each of its moons. Prove the existence of liquid water beneath Europa, demonstrate a liquid/slush ocean on Callisto, observe volcanoes on Io, and if you're just after pretty pictures, keep in mind that had Galileo's high-gain antenna actually worked, we'd have gotten thousands of times as many pictures as we did.

      Naw, scrap that science stuff. It's only good for a couple of years of billion-dollar pork while it's under construction, but once it's in the air, it's just a few million bucks worth of lousy scientists. Screw that. We need more shuttle/ISS flights, because they're the only things that can keep that gigadollar NASA contractor pork flowing for decades.
