comet is shown after the impactor probe from the Deep Impact spacecraft
collided with the comet early Monday, July 4, 2005. The successful strike
83 million miles away from Earth occurred just before 11 p.m. PDT,

Pasadena, Calif., which is managing the 333 million USD mission. (AP)

July 4 - A space probe hit its comet target late Sunday in a
NASA-directed, Hollywood-style mission that scientists hope will reveal
clues to how the solar system formed.
It marked the first time a spacecraft touched the surface of a comet.
The successful strike 83 million miles away from Earth occurred just
before 11 p.m. PDT, according to mission control at NASA's Jet Propulsion
Laboratory in Pasadena, which is managing the million mission.
Scientists at mission control erupted in applause and gave each other
hugs as news of the impact spread.
"The navigation was perfect, and the impact was bigger than I expected,"
said one of the specialists from the Jet Propulsion Laboratory here
shortly after the impact. "I can't imagine how this could have gone any
better."
It was a milestone for the U.S. space agency, which hopes the million
experiment will answer basic questions about the origins of the solar
system.
The cosmic smash-up did not significantly alter the comet's orbit around
the sun and NASA said the experiment does not pose any danger to Earth.
