DEEP NEWS
Newsletter for the Deep Impact mission
Issue 5 - November 2003

The Deep Impact spacecraft is expected to make a football stadium sized
crater in Comet Tempel 1 on July 4 of 2005 making a large enough impact to
be visible through telescopes on Earth. This is your chance to get all the
latest news on our progress. For more information on the Deep Impact
mission, visit:

STARRY STARRY NIGHT
Do you know that you can look up into the sky and see some of the stars that
the Deep Impact instruments will use to establish calibrations to measure
Comet Tempel 1's size and shape?

PLANETARY SOCIETY SENDS THEIR NAMES TO COMET TEMPEL 1
The Planetary Society recently submitted all member names (over 71,000) to
the Send Your Name to a Comet campaign and will now be part of the CD that
will be attached to the impactor that makes a deep crater in Comet Tempel 1.
Is your name there yet? If not, here's your chance to join the Planetary
Society on their trip to a comet.

MEET HAROLD MONTOYA
Harold used to wander fields when he was a kid looking for old pieces of
lumber and parts of bikes and lawnmowers so he "could build stuff." Now he
works for Ball Aerospace & Technologies Corp. where the Deep Impact
spacecraft is being built. Did he know he'd end up building spacecraft? His
mother has a picture he drew as a child showing himself riding a rocket to
space. "How scary is that?" asks Harold.

ACTIVITIES FOR YOUTH AND COMMUNITY GROUPS
Need an idea for your community family night or science fair? Here are some
great Deep Impact activities and ideas for kids and families in your area.

BRAIN TWISTER - THE IMPACTOR SPACECRAFT LOST WEIGHT?
If your job is to make as big a crater as possible in Comet Tempel 1, it
makes sense to put as much mass into your projectile (our impactor
spacecraft) as possible. Right? Recently, the impactor came up 10 kg (almost
a 25 lb bag of flour) lighter than planned. Did the team add the extra
weight back in? And if they did, where did they put it? The answer isn't as
easy as you might think. Can you figure out what the team did? Here are your
clues:

As the impactor is facing the comet, the back (aft) of the impactor is the
part that came up light.
The team realized some consequences of the weight loss during a spin balance
test when they found that the loss had put the impactor out of balance.
It is more important that the impactor be in balance than it is to have the
extra weight.
The electronics for the spacecraft are in the back half and the cratering
mass is in the front (fore) half.

The Deep Impact mission is a partnership among the University of Maryland
(UMD), the California Institute of Technology's Jet Propulsion Laboratory
(JPL) and Ball Aerospace and Technology Corp (BATC). Deep Impact is a NASA
Discovery mission, eighth in a series of low-cost, highly focused space
science investigations. See http://deepimpact.jpl.nasa.gov or our mirror
