China's Chang'E 2 Succeeds In Thrilling Asteroid Flyby 88

Zothecula writes "China has now joined the very select group of countries to have succeeded in carrying out an interplanetary probe mission. According to reports from China's official news agency Xinhua, the Chang'E 2 probe passed a mere 3.2 km (2 miles) from the near-Earth asteroid Toutatis at 8:30:09 GMT on December 13, making it the closest asteroid flyby to date ... and resulting in some remarkable photographs."

    How can 3.2km be the closest asteroid flyby when Hayabusa returned a sample from an asteroid?

    I guess I'll have to RTFA...

    • Because China is always better than Japan.

      Quick test: ask any Chinese who beat Japan in WWII. The island-hopping campaign, the atom bombs, and the Soviet invasion of Manchuria had nothing to do with it. Nope, Mao Zedong all the way. Despite the fact that he fought the Japanese, like, twice during the whole war.

      Arguably that's a fly-to, not a fly-by.

    • Maybe they are pointing to the impressive guidance needed to pass an object at 3.2km range and 10 km/s speed.

      Well, Hayabusa was a specific asteroid probe sent on a seven year mission to an asteroid in its orbit. Chang'E 2 was a lunar orbital probe launched in 2010 that was redirected from its parking orbit in April to approach Toutatis at the last minute when the asteroid happened to come close to Earth. The two are very different types of missions.

    Another damned link that talks about photos, MOTHER FUCKER THEY'RE AMAZING PHOTOS!!!!, and then doesn't provide them.

    It does provide an artist's conception...of the spacecraft.

    • If this thrilling flyby is real, their PR department should be fired.

      They only linked to this in TFA, so you are right, but this time its easy to find it.

    • Speaking of the photos, you'd think that a rag called "gizmag" would know that the usage is "cum" and not "come" as it appears in the caption. I'd give a link, but ... well, I'll let someone else search for "cum" at work.

    Ok.. so I went to the article and saw the link to the Chinese site with the pics... http://news.xinhuanet.com/english/photo/2012-12/16/c_132043872_6.htm [xinhuanet.com]

    All I can say is WTF... while the picture of the asteroid is interesting. There's a dozen photo galleries below it with photos that I would NOT want to be shared with friends and family...

    For example... an "Underwear Show" "Top Bikini babes..." "Contortionist..."

    Time to find another site without the BS...

    Chang'E's flyby of 4179 Toutatis is certainly an impressive feat. But, given that Hayabusa took samples while several meters above the surface of 25143 Itokawa, and that NEAR-Shoemaker actually landed on 433 Eros, I don't see how the term "closest" (which the article uses as well as the summary) can apply. Unless they mean "the asteroid flyby mission that took place nearest to Earth," which, while interesting, doesn't seem to be how this is being presented.

      Some of the source articles from which Gizmag stole this story referred to this being the closest flyby of this particular asteroid. The wording was such that when I first skimmed one of them even I thought the claim was that this was the closest approach to any asteroid. When I went back and parsed the whole sentence it became much clearer - Gizmag must never have read their sources carefully.

      • Well I am sure that some of the new agencies and their reporters there at Chinese mission control, such as Reuters and AP, could clear this up...oh wait....this was a Stalinist mission and closed to press. And I am sure that the only reason we are getting any information from these paranoid nut jobs is that the mission was successful.

      You can't compare the two scenarios.

      In a flyby the probe is moving really fast relative to the asteroid. It thus can't produce enough delta-v for a last minute avoidance maneuver. The trajectory is determined well before the encounter. How close you can safely get depends on how accurately you can predict the asteroid path. A few kilometers at close approach with a reasonably low risk of collision is pretty good.

      If you enter orbit first the situation is completely different. You can gradually lower the orbi

      • by Bomazi (1875554)

        I realize I should have just said that a flyby and an orbit are two different things, and that the article is therefore correct. Explaining why it is easier to get close to an object when you are orbiting around it than when you are flying past it is irrelevant.

        P.S.
        I hope that the reason /. doesn't have an edit button is because Bezos patented it. Seriously guys, it is 2012.

    Slashdot editors' memory is getting really short. This is essentially the same story already post just two days ago! And nothing new in this one.

  • Before you anoint our Chinese overlords, be aware that most of this technology was stolen from NASA/JPL. There is a reason China was (basically) kicked out of NASA

      kicked out of NASA

      Considering your other ignorant and racist comments in the thread I guess I shouldn't be surprised that you're unaware NASA isn't a multi-national organization. That first 'N' in the name? It stands for 'National'. China was never a 'member' of NASA that could be kicked out, no other country ever was.

  • on December 13, making it the closest asteroid flyby to date

    A record to be shattered on the 21st...
       

  • And when they find the probe, there's gonna be a *made in china* sticker on it :p

  • It was just a little gravitational push that the probe exerted on this asteroid. I wonder how much closer to the earth it will be when it comes around in 145 years time?

Money will say more in one moment than the most eloquent lover can in years.
