Description:
The OSIRIS cameras (optical, spectroscopic, and infrared remote imaging system) onboard the European Space Agency's Rosetta spacecraft observed comet 9P/Tempel 1 for 17 days continuously around the time of NASA's Deep Impact mission. The cyanide-to-water production ratio was slightly enhanced in the impact cloud, compared with that of normal comet activity. Dust particles were flowing outward in the coma at 〉160 meters per second, accelerated by the gas. The slope of the brightness increase showed a dip about 200 seconds after the impact. Dust Afrho values before and long after the impact confirm the slight decrease of cometary activity. The dust-to-water mass ratio was much larger than 1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keller, Horst Uwe -- Jorda, Laurent -- Kuppers, Michael -- Gutierrez, Pedro J -- Hviid, Stubbe F -- Knollenberg, Jorg -- Lara, Luisa-Maria -- Sierks, Holger -- Barbieri, Cesare -- Lamy, Philippe -- Rickman, Hans -- Rodrigo, Rafael -- New York, N.Y. -- Science. 2005 Oct 14;310(5746):281-3.
