Here's a photo of Vesta that was released by the Dawn team on Friday. I didn't post it right away because the version of the image in the official release has some bizarre processing artifacts that make it look as though the image had been made by cutting construction paper.

JAXA held a press conference on June 30 about the latest report from the review board that is charged with finding out what exactly caused Akatsuki's failure to enter orbit at Venus, and what that implies for the possibility of Akatsuki to try again when it returns to Venus in 2015 or 2016.

Opportunity 'burned up' the Meridiani Plains in June as it raced toward its much-anticipated next destination and the Mars Exploration Rover (MER) mission cruised into the 90th month of what was originally to have been a 90-day tour.

Time again for my monthly look at what's going on with the robots exploring the solar system! It'll be a month full of routine activities for our intrepid explorers performing ongoing science at Mercury, Venus, the Moon, Mars, and Saturn.

It's not easy to wrap a ginormous rover for shipping. I was glued to the feed from the Curiosity Cam all day yesterday, as they prepared Curiosity for shipping to Kennedy Space Center. Here's a low-budget time-lapse of the rover being wrapped.

According to an article published a week ago by the Xinhua news service, Chang'E 2 departed the Moon on June 9 at 09:10 UTC. It's now headed toward a Lagrangian point in space, but not the one I thought it was headed for.

One big space event that I missed while I was on vacation was Rosetta's entry into hibernation. Rosetta is the biggest interplanetary spacecraft that has been launched by ESA, and it has the groundbreaking goal of entering orbit around a comet and dropping a lander onto it.

The Mars Exploration mission suffered the loss of Spirit and shifted to one-rover operations in May, but Opportunity carried on, blasting across the plains of Meridiani to within 2 miles (3.5 kilometers) of its next major destination and discovery.

Dawn remains healthy and on course as it continues to approach Vesta. Thrusting with its ion propulsion system, as it has for most of its interplanetary journey so far, the spacecraft is gradually matching its solar orbit to that of the protoplanet just ahead.

The intensified effort to recover Mars Exploration Rover (MER) Spirit came to an end early Wednesday morning Pacific time and NASA has now transitioned the mission to a single-rover operation focused on Spirit's still-active twin, Opportunity.

Yesterday, I remarked that despite the declaration of her death we'll be seeing Spirit frequently over the next few years, as long as Mars Reconnaissance Orbiter is still monitoring her landing site with its HiRISE camera. I said that Spirit is a lump that's relatively easy to spot because of her dark shadow. Well, Spirit's managed to make herself even easier to spot than that.

Alicia Chang reported today that, according to project manager John Callas, the last attempt to uplink a command to the Mars Exploration Rover Spirit will be made tomorrow. NASA will cease listening for signals from Spirit on Tuesday.
