The launch has been scrubbed once again due to a critical hydrogen leak detected once fueling had been underway for a while.

It was a very happy set of scientists, engineers, managers, and administrators who filled the Jet Propulsion Laboratory's Von Karman auditorium this afternoon to do the postgame show on Deep Impact's flyby of Hartley 2.

Those of you who follow my blog must have known this was coming: now that I got all five new Deep Impact images of Comet Hartley 2 posted and explained, I had to make an animation. Here they are.

Here's the five close-approach images of Hartley 2 captured today, November 4, 2010, by the Deep Impact spacecraft, collected into one file. Boy, do these images reward close examination!

What a dramatic and cool photo! An asteroid with two lobes like Borrelly, lumpy and bouldery like Itokawa, with gorgeous active jets, dramatically lit. Well done, Deep Impact team!

Just a very brief update to congratulate the Deep Impact team on what was apparently a successful flyby of Hartley 2!

Discovery has suffered an electrical problem related to one of the main engines. Thanks to delays related to that, and to weather concerns, the launch was scrubbed until Friday at 3:04pm.

According to the mission timeline, the Deep Impact high-resolution observations of Hartley 2 are beginning in just a few minutes, at 20:50 according to the clock on the spacecraft.

Travel to Kentucky for the 176th Carnival of Space -- bet you didn't know Kentucky had space industry!

Continuing its journey to collect treats in the main asteroid belt, Dawn is making excellent progress toward its July 2011 rendezvous with protoplanet Vesta.

Mat Kaplan is at the Kennedy Space Center, 22 hours before shuttle Discovery is due to launch. Parts of the KSC are old and uncared for, while others are at the bleeding edge of space-flight technology.

A brief musing on the public opinion of the shuttle when it was first unveiled, and now, as it's about to be retired.

Since comet Hartley 2 -- the target of Deep Impact's November 4 flyby -- is near its perihelion, it's no surprise that it's an active comet with lots of outbursts.

Just a linky post here.

The week is finally here: Deep Impact flies past Hartley 2, the smallest comet yet to be visited by a spacecraft, on Thursday, November 4 at 13:50 UTC.

For the Mars Exploration Rovers, October was a lot like September, which was a lot like August: Spirit continued hibernating at Gusev Crater or so it appears since the rover didn't phone home; and Opportunity picked up the pace to Endeavour Crater again, setting new driving records and marking more milestones along the way.

Comet Hartley 2, the target for Deep Impact's close flyby (now just six days away!) made its closest approach to Earth on October 20, at a distance of 17.7 million kilometers.

The Cassini Raw Images Website always offers rewards to the browser. This evening I found the raw images necessary to create this color composite, showing the hazy orange moon Titan, the mid-sized icy moon Dione, and the tiny rock Prometheus all at the same time.

(I promise that this post will get around to the subject of space exploration in a couple of paragraphs.)
