Cheat sheets for Vesta's craters and Dawn's Vesta timeline

Posted by Emily Lakdawalla on 2012/04/19 01:38 CDT

I made myself a cheat sheet to many of Vesta's distinctive-looking craters, and also wrote down a list of the major dates in the timeline of Dawn's exploration of Vesta.

Dawn Journal: Saluting the Sun

Posted by Marc Rayman on 2012/03/29 05:19 CDT

On April 18, Dawn will attain its greatest separation yet from Earth, nearly 520 million kilometers (323 million miles) or more than 3.47 astronomical units (AU). Well beyond Mars, fewer than a dozen spacecraft have ever operated so far from Earth. At this extraordinary range, Dawn will be nearly 1,400 times farther than the average distance to the Moon (and 1,300 times farther than the greatest distance attained by Apollo astronauts 42 years ago). The deep-space ship will be well over one million times farther from Earth than the International Space Station and Tiangong-1.

More Dawn Vesta approach images: first color views

Posted by Emily Lakdawalla on 2012/02/17 11:37 CST

�On June 30, Dawn stopped thrusting for a full Vestian day -- five hours and 20 minutes -- and just watched the asteroid rotate. But unlike the previous observations, they used all of Dawn's�color filters�to acquire the best-ever color photos of the lumpy world.

What do Dawn's color ratio images of Vesta mean?

Posted by Emily Lakdawalla on 2011/11/01 07:58 CDT

The Dawn mission to Vesta continues to release an image every day, and recently they have been releasing lots of color images. I like color pictures for aesthetic reasons, but color is actually a very important property of planetary surfaces.

Science from Vesta at the Geological Society of America meeting

Posted by Emily Lakdawalla on 2011/10/24 05:55 CDT

I'm nearly two weeks late getting to this news but better late than never, right? There was a press briefing from the Dawn mission at the Geological Society of America (GSA) meeting on October 12.

Lovely pic of a recent crater on Vesta

Posted by Emily Lakdawalla on 2011/10/11 08:28 CDT

With little fanfare, the Dawn mission continues releasing a new picture from Vesta every day. This one is definitely my favorite among their recent releases, a closeup on one of Vesta's strange streaky bright craters.

Dawn Journal: Fourth year in space, and arrival in HAMO

Posted by Marc Rayman on 2011/09/29 08:12 CDT

Dawn's fourth anniversary of being in space is very different from its previous ones. Indeed, those days all were devoted to reaching the distant destination the ship is now exploring. Celebrating its anniversary of leaving Earth, Dawn is in orbit around a kindred terrestrial-type world, the ancient protoplanet Vesta.

Dawn's cryptic image release titles

Posted by Emily Lakdawalla on 2011/09/14 04:44 CDT

Every day's image release from the Dawn spacecraft shows something on Vesta that is weird and cool and difficult to explain. The images come out with very little information describing what is going on to make those weird landscapes.

Dawn Journal: Spiraling Down from Survey Orbit

Posted by Marc Rayman on 2011/09/02 11:39 CDT

Dawn has completed the first phase of its exploration of Vesta with tremendous success, and the peripatetic adventurer is now in powered flight again, on its way to a new location from which to scrutinize its subject.
