'When NASA=E2=80=99s Deep Impact mission ploughed into comet 9P/Tempel 1 on
July 4th of this year, the giant telescopes on Mauna Kea had a unique
view of the massive cloud of dust, gas and ice expelled during the
collision. See previous Gemini release on observations here.cache ...'

collision, which is estimated to be as much as 25 fully-loaded tractor
More specifically, ...' a firm estimate of the mass ejection, which was

' Rosetta, with its set of very sensitive instruments for cometary
investigations, used its capabilities to observe Tempel 1 before,
during and after the impact.
At a distance of about 80 million kilometres from the comet, Rosetta
was in the most privileged position to observe the event. ...
..=2E. The 370 kg copper impactor hit Comet Tempel 1 with a relative
velocity of 10.2 kilometres per second. The collision was expected to
generate a crater with a predicted diameter of about 100-125 metres and
eject cometary material. It vaporised 4500 tonnes of water, but
surprisingly released even more dust. ...'
' ...Because the spacecraft was unable to study the size of the crater
created after it was formed, the high-resolution Mauna Kea observations
provided the necessary data to get a firm estimate of the mass
ejection, which was about 1000 tons. "To release this amount of
material, the comet must have a fairly soft consistency," Sugita said.
..=2E."The splash from NASA's impact probe freed these materials and we
were in the right place to capture them with the biggest telescopes on
Earth," said W.M. Keck Director Fred Chaffee. "The close collaboration
among Keck, Gemini and Subaru assured that the very best science was
done by the best telescopes in the world, demonstrating that the whole
is often greater than the sum of its parts." ... '
