Stardust update: Almost to Tempel 1

We're coming up on the final days of Stardust's approach to Tempel 1. The flyby takes place on February 15 at 04:56 UTC (February 14 at 20:56 PST).

Close approach to Earth turns Apollo into Aten

Last week we got buzzed by a very small asteroid, something that happens fairly often. But there were several details that made the close approach of asteroid 2011 CQ1 worthy of note.

Some recent pictures of Saturn's northern storm

There is a huge storm that's spreading across so much of Saturn that it's been readily visible even from Earth-based telescopes. Over the past couple of days a couple of new images of Saturn have appeared that show just how enormous the storm is today.

Rosetta update: Scary safe mode, but all's well now

The Rosetta blog has been strangely quiet of late, after they had been quite actively posting updates on the status of Rosetta during a critical series of orbit adjustment burns, which I wrote about two weeks ago.

Dawn Journal: ORT ORT ORT

Dawn continues its flight through the asteroid belt, steadily heading toward its July rendezvous with Vesta, where it will take up residence for a year. On January 10, Dawn performed some of the activities that it will execute in its low altitude mapping orbit (LAMO) at Vesta.

Stardust update: trajectory correction successful

Now that Stardust has images of its target comet to work with, the mission was able to figure out their relative positions more precisely, and they've gone ahead with an important rocket firing that shifts the spacecraft's aimpoint past the comet closer to the number that they want.

Io and Jupiter from Voyager 1

Here's an image I've been meaning to post for months, a new mosaic from Voyager 1 by Ted Stryk of Io crossing Jupiter's terminator as it neared closest approach.

Uranus and Challenger

In the past week there have been 25th anniversaries of two events in 1986, one great, one terrible: the closest approach of Voyager 2 to Uranus on January 24, and the explosion of the space shuttle Challenger upon liftoff on January 28.

Butterfly crater on Mars

I've spent the day noodling around in the current issue of Icarus, following up some of the more interesting stories within its table of contents, and came across a picture of this very cool crater -- actually, set of craters -- on Mars.

Stardust update: Tempel 1 Ahoy!

It is with great relief that I now report that JPL announced this evening the sighting of Tempel 1 by Stardust, a mere month before the planned flyby.
