More about Comet 9P/Tempel 1, Deep Impact and ... those wacky Japanese & ESA astronomers! SUBTITLED "What's an order of magnitiude difference amongst friends & scientists, anyway ? "
Remember this ...
'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 ...' And the "here" http://tinyurl.com/crt44 ' Deep Impact Captured by Gemini Print Saturday, 02 July 2005 ~~~~~ STILL dated 2 days BEFORE impact! The Gemini North telescope on Mauna Kea successfully captured the dramatic fireworks display ... ' =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3 D=3D=3D=3D=3D=3D=3D=3D HERE IS A NEW ANOMALY! 'Subtitled' as ... What is an order of magnitiude amongst friends & scientists, anyway ? ESA claims the impact liberated '4500 tonnes of water + even MORE dust ' Let's say 10,000 tons for argument sake ( 12 October 2005 ) Subaru Telescope claims 'the mass of material blasted out by the collision, which is estimated to be as much as 25 fully-loaded tractor trailer-trucks.' More specifically, ...' 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. ...' ( September 15, 2005 ) 1 or 10 kiloton mass of ejecta ... Which is it ? Am I missing something here ? See refs. below ... http://www.universetoday.com/am/publ....html?13102005 for provided the intial information. ----------------------------------------------------------- ' 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. ...' See http://www.esa.int/esaCP/SEMUSK5Y3EE_index_0.html ' ...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. ..=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." ...
