Dawn Journal: Riding gravitational currents to HAMO2

Posted by Marc Rayman on 2012/06/05 03:30 CDT

Dawn is beginning its departure from Vesta, spiraling upward from its low-altitude mapping orbit to a higher one from which it will map north polar terrain not visible during the earlier mapping orbit.

What's up in the solar system in May 2012

Posted by Emily Lakdawalla on 2012/05/01 10:16 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. This month's highlight: Cassini's about to fly close past Enceladus and Dione.

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.

An update on Opportunity, and a plea for some volunteer desktop publishing help

Posted by Emily Lakdawalla on 2012/04/03 05:00 CDT | 2 comments

A. J. S. Rayl has just posted her monthly update on the goings-on at Meridiani planum, noting that the update recaps the 99th month of the Mars Exploration Rover mission. There's a lot of detail on how the radio-tracking campaign is going. While she's not driving, Opportunity's acting like a lander, with radio antennas on Earth performing Doppler tracking to allow very fine measurement of Mars' orbital motion.

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.

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.

What's up in the solar system in March 2012

Posted by Emily Lakdawalla on 2012/03/27 02:53 CDT

This month will see GRAIL begin its science mission measuring the Moon's gravity field. MESSENGER will complete its primary mission at Mercury, celebrating its one-Earth-year-in-orbit anniversary with a big data release, and immediately begin work on its one-year extended mission. Mars will pass its solstice, ushering in warmer days for Opportunity. Coincidentally, this month will see Jupiter's southern winter solstice, too, though there are no spacecraft there to notice it. Out at Saturn, Cassini will have two encounters with Enceladus this month, one of them distant, one of them at 74 kilometers altitude.
