It should give you a feeling of déjà vu: a defunct satellite's orbit is decaying, and because that orbit is circular it's going to be impossible to predict where and when along its ground track it's going to happen.

Kennedy Space Center has recently created a photo album collecting their photos from the clean rooms where technicians are working madly to prepare the Curiosity Mars rover for launch.

Today I largely spent in the MESSENGER sessions. They have a lot of data to talk about.

Since leaving the plains of Meridiani, pulling up to Endeavour Crater and checking out its first rock last month, Mars Exploration Rover Opportunity has wasted no time in getting the "new mission" underway.

Without a doubt the most exciting events in space in October are Cassini's two, count them, two extremely close flybys of Enceladus, spaced only eighteen days apart, on October 1 and 19 (and followed by a third one on November 6).

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.

The world watched on Friday as the derelict spacecraft named UARS made its final few orbits around Earth. And then we waited for final word of its reentry location. And waited. And waited.

Unless you've been living under a rock you've probably heard that a very large Earth-orbiting satellite is going to be reentering Earth's atmosphere soon, and there's a small but nonzero chance of debris coming down where somebody might actually find it.

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.

More than seven and a half years after landing, Opportunity arrived at its long-anticipated destination, the rim of Endeavour Crater, and in less than three weeks found something strange enough to launch a new Martian mystery.

September is going to start with a bang: the twin GRAIL spacecraft are set for launch on September 8. I would love to be able to attend the launch but my older daughter's first day of kindergarten is September 7! That's a launch of a different kind.

The Mars Exploration Rover (MER) mission roves back into the exploration spotlight this month as Opportunity arrives at the rim of Endeavour Crater, a destination that wasn't even an impossible dream when the rover landed back in January 2004.
