Deep Impact: excavating comet Tempel 1.
Deep Impact collided with comet Tempel 1, excavating a crater controlled by gravity. The comet's outer layer is composed of 1- to 100-micrometer fine particles with negligible strength (<65 pascals). Local gravitational field and average nucleus density (600 kilograms per cubic meter) are estimated from ejecta fallback. Initial ejecta were hot (>1000 kelvins). A large increase in organic materi...
متن کاملDeep Impact : Excavating Comet Tempel
Introduction: On 4 July 2005, Deep Impact delivered 19 GJoules of kinetic energy to the nucleus of comet Tempel 1, taking numerous images and spectra of the comet before, during, and after the impact. The preliminary analysis of the data has already lead to significant, new understanding of cometary properties and behavior [1] and this talk will summarize the present state of our understanding ...
متن کاملTelescope Observations of Comet 9 P / Tempel 1 during the Deep Impact Encounter
We report on the Hubble Space Telescope program to observe periodic comet 9P/Tempel 1 in conjunction with NASA’s Deep Impact mission. Our objectives were to study the generation and evolution of the coma resulting from the impact and to obtain wide-band images of the visual outburst generated by the impact. Two observing campaigns utilizing a total of 17 HST orbits were carried out: the first o...

متن کاملCarbon Monoxide in Comet 9p/tempel 1 before and after the Deep Impact Encounter
One of the goals of the Hubble Space Telescope program to observe periodic comet 9P/Tempel 1 in conjunction with NASA’s Deep Impact mission was to study the generation and evolution of the gaseous coma resulting from the impact. For this purpose, the Solar Blind Channel of the Advanced Camera for Surveys was used with the F140LP filter, which is sensitive primarily to the ultraviolet emission (...
