Get NASAs Deep Impact Mission:

One of the most obvious results was seeing the size and shape just hours before encounter. The Deep Impact spacecraft sent back infrared spectra as well as optical images. Finding ice on the surface of Tempel 1 was an unexpected but very exciting result! Tempel 1 - What's It Really Like?

The primary mission of NASA's Deep Impact was to probe beneath the surface of a comet. The spacecraft delivered a special impactor into the path of Tempel 1 to reveal never-before-seen materials and provide clues about the internal composition and structure of a comet. Deep Impact spent almost nine years in space.

Deep Impact, which released an impactor on comet Tempel 1 to expose materials on its surface, revealed a number of new findings about comets and their composition, including evidence of water ice and organic materials.

DART was the first-ever mission dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid's motion in space through kinetic impact. On Sept. 26, 2022, DART impacted the asteroid moonlet Dimorphos, a small body just 530 feet (160 meters) in diameter.

Deep Impact: Interesting Mission Facts The Deep Impact flyby (observing) spacecraft is about the size of a Volkswagen Bus. The Deep Impact impactor (projectile) spacecraft is about 3 X 3 feet, about the size of a desk and weighs 370 Kg (820 lbs). The entire combined spacecraft weighs about 1 ton.

The Deep Impact mission was planned to help answer fundamental questions about comets, which included what makes up the composition of the comet's nucleus, what depth the crater would reach from the impact, and where the comet originated in its formation.

The Biederman fragment hits the Atlantic Ocean near Cape Hatteras, North Carolina, creating a megatsunami that destroys much of the East Coast of the United States, reaching the Ohio River Valley, and also hitting Europe and Africa. Millions are killed, including Sarah's parents, Lerner, and her father.
