Views of the Asteroid Toutatis, From Earth As Well As Close-Up 23

When Chinese probe Chang'e buzzed the asteroid Toutatis, it wasn't the only one watching. NASA's observatory in Goldstone, CA was taking radar images, which have now been assembled into a short (40-second) animation. The craft was recording the encounter, too, as reported by Sky & Telescope, which also gives a good summary of the history behind Chang'e's mission.

    Thumbs up for the chineese. As much as I don't like their politcs & government, I am really happy that they will hopefully start a new space race. All the humanity will benefit from that.
  • That gave me a little thrill. That's one of the building blocks of the future, folks, literally!

  • The radar images are great, but they're definitely not conventional photos - the viewpoint-from-Earth is actually from the 'top' of the image, looking down. They're constructed from a combination of distance measurements and Doppler shifts [planetary.org], the latter thanks to the rotation of the asteroid.

    So basically it means a single transmitter and single receiver can figure out a two-dimensional image from a vast distance - and it's nice that these images quite closely match the conventional, optical images taken by th

    In fact, that one small village that still holds out against the invaders, would all get a few goose-bumps from having an asteroid named after their favourite god.

    I have to assume that there's also a asteroid named Belenos and one named Belisima. Fun times reading those books - and now my kids love them. Thanks for bringing up the memories Slashdot.
