  • This should give you an indication of the size of the Dawn spacecraft as scientists prepared it for launch.

  • Here is the Dawn spacecraft with its ion propulsion system installed.

  • The ion propulsion system goes through a test on Earth. Dawn has three 30-centimeter-diameter (12-inch) ion thrust units. It produces an electrical charge to accelerate ions from xenon fuel that will be 10 times faster than chemical fuel.

    The spacecraft uses only 10 ounces of fuel per day and would accelerate on an Earth highway from 0 to 60 miles per hour in 4 days. But without gravity in space, its got speed to burn.

  • "Dark side"

    I'm thinking Vesta no more has a "dark side" than the Moon does. Vesta is a rotating body.

      Whats with this "dark side"reference? Citation, please.

      Ah but then perhaps you're on acid and listening to Pink Floyd, like I did 40 years ago?

        I don't think one has to be on acid to listen / feel the music of Pink Floyd - the greatest music talent(s) of all time - according to me that is!

    The (one) color picture, taken with The Hubble, makes it look like there are 'oceans' there! Something that would be REALLY cool but I highly doubt. . .

  • This is nothin' but a scam

    ... it's obviously a photoshopped image of swiss cheese.

    "This is what Vesta looks like from Earth courtesy of the Hubble Space Telescope." Ah, isn't the Hubble Space Telescope in space?

    "After traveling 1.7 billion miles over four years."

    I'm sorry but I could almost choke up when I read this and think about the Wright Brothers just getting airborne about a hundred years ago.

    After travelling 1.7 BILLION miles for 4 years, they are now 114 million miles from Earth

    LOL

      @OutOfBoxExperience <br>LOL?<br>I don't get it. What's the joke?<br>Perhaps <a href="http://www.universetoday.com/wp-content/uploads/2011/05/DawnfulltrajMay112011.jpg"><b>THIS </b></a> might explain to you the distance travelled.

        You mean the Road Runner didn't use his slingshot so Dawn could travel as the crow flies? Why not, it works on TV ;)
        LOL
