Crashed Spacecraft Yields Data on Solar Wind 44

Posted by CowboyNeal from the best-of-a-bad-situation dept.
Hugh Pickens writes "After the Genesis mission spent 27 months in space gathering tiny samples from different types of solar wind, Hollywood stunt pilots swooped in with a helicopter to catch the falling capsule when it returned to earth. Unfortunately the spacecraft's parachute did not open, and the spacecraft ploughed a hole into the desert. Now scientists are starting to recover data from the salvageable pieces of Genesis. Nature Magazine reports that an analysis of isotopes of neon and argon shows that the elements of main interest to the researchers have the same isotopic signature in the solar wind as in the Sun itself. Because dirt contains relatively little neon and argon, the current Science study wasn't affected too much by contamination and the the team remains hopeful that they will be able to get results on oxygen and nitrogen isotopes from the mission."

      It looks like a turd waiting to be painted gold.

      Yeah, the instruments and samples were so delicate that the researchers were afraid that a parachute landing would be too hard and destroy the samples. But, but, wait! We really didn't need the helicopters.

      And parachutes? We don't need no stinking parachutes!.

          Because they weren't planning to smash it into the ground, possibly contaminating the sample? It did crash, though, and with all the money they spent on it, they're working diligently to get what they can out of it.

          Obviously, we also know the composition of the atmosphere. If the isotope ratios are different from solar wind and they are actually more similar to terrestrial sources, the scientists might conclude the samples are contaminated while they are not. In all other cases, the analysis will produce correct results.

      TFA explains that they are publishing a series of papers. The quoted paragraph is about results on Neon and Argon which were published in Science. Other results were published elsewhere, such as Space Science Reviews.
    • There are probably several isotopes in the atmosphere, and several that aren't. If you find a lot of certain isotopes that are rare locally, then it's reasonable to suggest that it had come from elsewhere.

    I found it interesting that the article describes how Murphy's Law was not as general as most of us know it, stating more specifically that things that can be installed backwards eventually will be installed backwards, and that this is precisely what caused the parachutes to fail to deploy.

    Also can't say that I knew Murphy was a "rocket scientist", literally. How ironic. You'd think NASA would have learned from him by now?

    Genesis was no failure. Dr. Marcus was indeed very proud over it.
    • No, obviously this didn't work at all: There was no Genesis effect, otherwise I wouldn't be able to write this.
  • Solar wind comes from the sun, so why should the particles be any different than the measurements taken from the sun? It is nice to confirm that solar wind really comes from the sun, but hasn't that been confirmed a long time ago by simply looking at the direction of the flow?

    I watched it on NASA TV when it came in. It had a pretty good wobble, coming in at a 90 degree angle relative to the earth. Folks had kinda figured that it was going to do a pretty good job of splattering itself on the desert floor. Was a pretty good surprise when it just dug a divot and stayed pretty much intact. Some folks think that most of the lake beds are hard as rocks through and through. Some are not so.
    Back in the 60's, legends Chuck Yeager and Neil Armstrong took a Beech twin up for some landing practice on some of the salt flats. Neil set up on a approach for one such flat, on his judgment that it was dry and stable.. Yeager, being the "desert rat" knew of certain flats that stay muddy under the salt crusts, and the one they set up to land was just that. He told Neil that he should abort and go find another flat. Neil, being the analytical computer, declared that it would hold. The Beech's tires touched down on the crust, and proceeded to keep going down into the muddy substrate, sinking up to the struts, coming to a halt.
    So the Beech sat there shaking and vibrating, engines going at full throttle. Chuck, ever being the wisecracking pilot turned and said to Armstrong "I told you so". Neil turned to respond, and his computer for a brain clicked and went kerCHUNK! He had nothing to say in return. They hiked to another flat so a DC3 could pick them up on the run.
    • Armstrong with nothing to say? He was an awesome choice for first man on moon, but I wish that he felt some kind of obligation to talk about it more. He basically said thanks for the trip, now I'm going to retire leave me alone k thx bye.

      He's an inspiring man, I just wish he'd talk about it more.

    Does the "Five-second Rule" apply here?
