No Samples On Japan's Hayabusa Asteroid Probe

eldavojohn writes "Reports are coming in that JAXA's Hayabusa probe may have come up empty-handed in its bid to collect asteroid matter. There may be gas in the probe but no dust samples as many hoped. Murphy's Law seemed to ride with Hayabusa. 'After landing in 2005 on the Itokawa asteroid, which is about one-third mile long and shaped like a potato, the probe's sample-capture mechanism went awry. To the public's dismay, JAXA officials said they were not sure whether any samples had been collected. Next, the probe's robotic rover, meant to take photos and temperature readings on the asteroid, inexplicably floated off into space and was never heard from again. Worse yet, after Hayabusa took off from the asteroid, all four of NEC's ion engines shut down. So did all 12 of the chemical-fueled rocket engines made by another space industry giant, Mitsubishi Heavy Industries. The probe was left drifting in space. Then, for more than seven weeks, for reasons still not clear, there were no communication signals from the probe. Public dismay quickly turned to derision and, eventually, indifference.' The probe did return, however, and JAXA hoped to salvage something, but now it appears that the only thing it accomplished was one long and error-prone journey."

    If this is true it is very sad news. This probe had a lot of promise, and it's failure is to be regretted. Let's hope that JAXA is not put off trying other missions of this type...they deserve our support.

  3. Metric system.. Duh! by CajunArson · · Score: 5, Funny

    As is commonly cited here, everything NASA does screws up because stupid Americans don't use the metric system... if only the Japanese would use it they wouldn't have these prob...

    [hushed whispering] Uh.. it has come to my attention that some people believe Japan uses the metric system. This cannot be possible for 2 reasons: 1. With the metric system there can't be any stupid screwups like what the Americans do. 2. Japanese always have the most badass robots and this is just a space robot, and therefore must work. I stand by my original statement.

    Pretty good for a first try. Based on all other attempts to return physical samples from an extraterrestrial body, I'd say they got pretty close.

    The collection of samples was a bonus. The actual purpose of the mission was to test the ion-drive, which was fully successful as they ran for more than 1000 hours.

  11. Wrong, totally wrong. by Silm · · Score: 5, Informative

    The submitter of this article has no idea what he is talking about. It will take months to even be sure that there is something in there.
    The only tests that have been done to date on the canister is a CT scan which can only detect samples as big as a grain of sand, way bigger then was expected.
    The gas in the capsule might have come from evaporated organics / ice of some form. How was this gas detected? The top of the capsule behaved slightly diffirent ( on a sub-millimetre scale ) in various pressure surroundings ( Nitrogen and CO2 under various pressures )

    The container has not been opened yet. All this talk is bullocks. The japanese estimate right now is that it will take some MONTHS to come till they know if they have something. The tiniest of particles is enough for this.
    Furthermore, the source, a NYT article, does not reflect at all the actual goal of the mission - for this, I refer to wikipedia.
    Succes for Hayabusa is considered 100 points. I'll repeat that: Primary mission objective succes is defined as 100 points. You do the math.

    Operation of Ion Engines
    50 points Success
    Operation of Ion Engines for more than 1000 hours
    100 points Success
    Earth Gravity Assist with Ion Engines
    150 points Success
    Rendezvous with Itokawa with Autonomous Navigation
    200 points Success
    Scientific Observation of Itokawa
    250 points Success
    Touch-down and Sample Collection
    275 points Success
    Capsule Recovered
    400 points Success
    Sample obtained for Analysis
    500 points Uncertain

    This mission IS A BIG SUCCES. There is no other way to talk about it. In the NYT article it is stated this mission was a failure as soon as there is no dust.
    And next to that, as said above, it is absolute BS to talk about succes or not at this point.
