Mars Exploration Rovers Update: Opportunity Gets Energy Boost and Works Through Depths of Winter
Posted by A.J.S. Rayl on 2012/03/31 05:40 CDT
March came in like a lion and went out like a lamb at Meridiani Planum, Mars: Opportunity felt the cold wind on her solar panels, then "settled" in a little more, working through the depths of its fifth Martian winter, as the team honored one of its own up there, and the Mars Exploration Rover mission logged month number 99 of exploration.
What's up in the solar system in April 2012
Posted by Emily Lakdawalla on 2012/03/30 02:27 CDT
Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system! I count 16 spacecraft that are actively performing 13 scientific missions at Mercury, Venus, the Moon, Mars, Vesta, Saturn, and at the edge of the heliosphere.
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.
Moon Mappers citizen science project now public, and statistics show it works!
Posted by Emily Lakdawalla on 2012/03/29 02:04 CDT
Last week, Pamela Gay of CosmoQuest announced that their Moon Mappers citizen science project is out of its beta phase and ready for prime time. Moon Mappers enlists the help of the public to perform the gargantuan task of mapping the sizes and positions of craters photographed on the Moon by Lunar Reconnaissance Orbiter. Crater counting is the most powerful tool geologists have for figuring out how old planetary surfaces are. But when you have Terabytes of data, it's simply impossible for one scientist to count all the craters
La Sagra Observatory discovers very near-Earth asteroid 2012 DA14

With a new CCD camera configured to shoot rapid, short exposures bought with a Planetary Society Shoemaker NEO Grant we caught near-Earth asteroid 2012 DA14.
Hey amateurs! ESA's running an image processing contest: "Hubble's Hidden Treasures!"
Posted by Emily Lakdawalla on 2012/03/27 04:26 CDT
Here's a newly announced contest that is right up my alley and, I hope, of interest to regular readers of this blog. ESA has just announced "Hubble's Hidden Treasures," a contest to encourage what I've been trying to get people to do for years: trawl through the Hubble archives to find unappreciated tresures of photos and make them pretty for public consumption. They have two categories, one for newbies (who can use image processing tools provided on ESA's website) and one for more serious amateurs (who can use other software).
