Hot Topic Solar System Meteorites, Comets and Asteroids
 
X-ray Depth Vision
Topic: Meteorites, Comets and Asteroids
07/14/05
Here come the X-rays, on cue. Scientists studying the Deep Impact collision using NASA's Swift satellite report that comet Tempel 1 is getting brighter and brighter in X-ray light with each passing day.

Comet Was Ka-Powdered
Topic: Meteorites, Comets and Asteroids
07/09/05
Data from Deep Impact's instruments indicate an immense cloud of fine powdery material was released when the probe slammed into the nucleus of comet Tempel 1 at 6.3 miles per second. The cloud indicated the comet is covered in the powdery stuff.

Swift Witness to Comet Broadsiding
Topic: Meteorites, Comets and Asteroids
07/05/05
The Swift satellite is providing the only simultaneous multi-wavelength observation of the Tempel 1 dust-off, with a suite of instruments capable of detecting optical light, ultraviolet, X-rays and gamma rays. Different wavelengths reveal different secrets about the comet.

Photo Finish
Topic: Meteorites, Comets and Asteroids
07/05/05
One of the fascinating elements of collecting the different images from the Deep Impact mission is comparing and contrasting the same event seen through different lenses. Seeing the comet collision in color is no exception.

Impact!
Topic: Meteorites, Comets and Asteroids
07/04/05
The Deep Impact mission proceeded exactly as planned, with the impactor spacecraft smashing into the sunlit side of comet Tempel 1.

Tempel to the Telescopes
Topic: Meteorites, Comets and Asteroids
07/04/05
Two space-based assets, the Hubble Telescope and the European X-ray observatory, closely monitored the first ballistic impact of a comet. The early results show a icy interior and perhaps the large debris cloud points towards a harder model for the comet nucleus itself rather a slush or loose rubble pile.

Crash Course in Comet Construction
Topic: Meteorites, Comets and Asteroids
07/04/05
Comet Tempel 1 was hit hard by a NASA spacecraft earlier today. Deep Impact scientists provided more details about what the impact has taught us about the comet's structure.

Impactor Away
Topic: Meteorites, Comets and Asteroids
07/03/05
One hundred and seventy-one days into its 172-day journey to comet Tempel 1, NASA's Deep Impact spacecraft successfully released its impactor. The separation of flyby spacecraft and the washing-machine-sized, copper-fortified impactor was one in a series of important mission milestones.

The Pause before the Crash
Topic: Meteorites, Comets and Asteroids
07/01/05
The Deep Impact spacecraft is nearing the comet Tempel 1. On Sunday, July 3, a smaller spacecraft will separate from the mothership, ready to sacrifice its life for the benefit of cometary scientists everywhere.

Rip Van Satellite
Topic: Meteorites, Comets and Asteroids
06/28/05
A dormant satellite awakens from its hibernation to witness the July Fourth collision between a comet and another probe, the Deep Impact mission.
