Dawn Rendezvous With Vesta Rock animation

July 25, 2011

I saved individual frames from Dawn simulator images covering 2 weeks as the spacecraft arrived at Vesta and created a Dawn rendezvous set at Flickr.  Play them as a slideshow! (Let the slideshow run once first to download the images, then it should run faster on replay.  For me, slides display at 3 second intervals, resulting in a two minute animation.  Your flickerage will vary.)
Simulation courtesy of Gregory J. Whiffen, JPL.  I encourage him to do an official time-lapse, once he has time out from frequent Vesta texture map updates.  He has other Dawn viewpoint sims and charts at http://dawn.jpl.nasa.gov/mission/live_shots.asp

This animation is made of frames from this feed:

Dawn spacecraft arrives at Vesta rock’s orbit

Here’s the initial image, pic, picture, photo, and photograph of Vesta from orbit.  (I’ve noticed all the different search terms people are using for images.  Smile.)

After a year of shifting survey and mapping orbits, Dawn will relight its drive and start the 2 year and nine months flight to Ceres.  This will add another 20,000 hours of powered flight to the flightlog of these incredible engines; three are aboard Dawn, taking turns shaping its orbit with the 5-millionths of a earth gravity strength ion-drive thrust.
