Deep Impact
« on: July 01, 2005, 12:08:34 AM »
My name, along with another 625,000 people’s names will be part of the July 3-4 fireworks when Deep Impact impactor spacecraft collides with Comet Tempel 1.

When Deep Impact was in its final stages of development, organizers in NASA's Education and Public Outreach program created the Send Your Name to a Comet campaign.
The Internet-based effort allowed participants to sign their name up for destruction and print out an official certificate documenting their place on the list.

"We thought it would be fun for people to say their name was on the impactor that collided with the comet. We thought it would let them feel like they were part of the mission." - Maura Roundtree-Brown, organizer.

People could submit their names between May 2003 and January 2004.
Once registration closed, the list was burned onto a mini-CD and attached to the spacecraft -- tucked under the thermal blanketing...to keep it safe until it vaporises during this holiday weekend when the impactor and comet slam together at 37,000 Km/h.

"It will be vaporized along with the impactor"

Though, NASA will have to wait until Monday to see if they hit the mark with their impactor...

The nominal impact time is July 04 05:52:00 UTC, +/- 3 minutes, Earth received time.
The actual impact should occur about 07:15 minutes earlier due to the light time delay.
Current orbit solutions using astrometry determination from last night, says that impact will occur about 15 Seconds late. (The 1-sigma uncertainty is around 12 seconds)

The best Earth view will be over Hawaii…but a huge cloud may emerge that may brighten the comet for several hours…so that it’ll be visible through binoculars…

My official certificate  :-)

Hum,
yeah...

I put together some images of the final moments of the cdrom HERE.


i hope they made a backup of that disk...

Hum,
yeah,
even though Tempel 1 is aout the sze of Manhattan, the odds were 50:50 that they hit the mark...

And it seems that they were lucky that they hit where they did  (the comets shaped like an elongated potato) and not to make any major course changes with the impactor...


(10kb)
They hit right at the bottom part beside the distinctive crater rim.

@Mr Spielberg
Hum,
Why not make the martians the heros in `War of the worlds`?

By toutatis!

The strange thing is that the comets consistency is similar to mashed tatties..."For Mash Get Smash" ...(but made up of water ice, co2, silica etc…)

Hum,
Well simply, by looking at the size of the crater it left was an easy way to find out what it was made of…

But a lot more can be found out by looking at the spectral (light) from the dust.
So we now know its composition and make up…its very dusty, and not solid…which may help us out in the future….

The main reason for the mission, imho, is to avoid the fate that befell the dinosaurs…
So quite cheap compared with that.

Landing on a comet and taking samples from lots of location would be a better option, and there is one on its way to do exactly that.

Europe's Rosetta space mission will land a probe on to the comet Churyumov-Gerasimenko in 9 years time…

Mark it in your diary…
