Tempel 1 Impact Day After Tomorrow

TerminaMorte wrote to mention a news.com article detailing the impending contact of the "Deep Impact" satellite with the Tempel 1 comet...at roughly 23,000 miles per hour. from the article: "We know that the crust--the outside shell of a comet and the stuff that comes off a comet--is changed by the solar wind...One of the things that we're curious about is, some people will tell you that comets actually produce organic compounds...We want to see if that's inside." Update: 07/02 22:08 GMT by Z : Updated with correct day.

Not tomorrow, but the day after

In fact, Tempel 1 will impact on July 4th at 05:52 UTC

The impact? No.

But if you wanted to try to see it pre-impact, you'd look (with a telescope or binoculars - it shouldn't be naked-eye) near Spica in the constellation Virgo; the comet will be near it, in the direction of Arcturus in the constellation Bootes.

If you have no idea where Spica and Arcturus are... find the Big Dipper. Follow the curve of its handle, and look across the sky a ways for a bright kinda yellowish star. That's Arcturus. Then look about that far again for a bright bluish star. That's Spica.

Or, get yourself on a flight to Maui ASAP and head over to Maui Community College, where a bunch of us will be doing a public outreach program featuring things like NASA people, live video links to observatories on Mauna Kea and Haleakala, and so on and so forth. And freebies. :)

I've only been involved with DI-related stuff for 10 months (as a telescope operator, and now for outreach) but some folks I work with have been on this for the better part of 10 years, so I hope everything goes well!

Been done before

The Apollo moon missions were observed telescopically by both amateur and professional astronomers. A terrestrial observatory even provided critical tracking information for Apollo 13's final course correction.

Protons can't escape from stars, silly. All the tons of gravity would get in the way.

He wrote "photons". And even protons escape stars. Did you ever hear of solar wind?

I hope it's correct :)

Re:Not really 23,000 miles an hour

[jswhitten]

23,000 miles per hour is the relative velocity.

Both the Deep Impact spacecraft and comet Tempel 1 are in their own unique orbits around the Sun. However, the comet is traveling substantially faster (29.9 kilometers per second (66,880 miles per hour)) than the spacecraft (21.9 kilometers per second (48,990 miles per hour)). ... the comet actually runs over it at a relative velocity of 10.3 kilometers per second (about 23,000 miles per hour).
