The Deep Impact encounter with the nucleus of 9P/Tempel ejected small grains (a ~ 100 micron) ejected by the impact will likely have the lowest ejection velocities and will weakly interact with solar radiation pressure. Therefore, large particles may remain near the nucleus for weeks or months after ejection by Deep Impact. We present initial highlights of our Spitzer Space Telescope/MIPS 24 micron camera program to image comet 9P/Tempel at 30, 80, 420, and 560 days after the Deep Impact… Expand

Subaru Telescope Observations of Deep Impact
Mid-infrared data from the Cooled Mid-Infrared Camera and Spectrometer (COMICS) of the Subaru Telescope indicate that the large-scale dust plume ejected by the impact contained a large mass and formed two wings approximately ±45° from the symmetric center, both consistent with gravity as the primary control on the impact and its immediate aftermath.

The Dust Grains from 9P/Tempel 1 Before and After the Encounter with Deep Impact
Dust ejected from the nucleus of comet 9P/Tempel 1 before and after its encounter with Deep Impact left a smooth featureless spectrum, similar to that observed before the impact, suggesting that the impact did not produce a new active region releasing small particles on the nucleus. Expand
Photometry and Imaging Results for Comet 9P/Tempel 1 and Deep Impact: Gas Production Rates, Postimpact Light Curves, and Ejecta Plume Morphology
We present Earth-based imaging and photometry results of Deep Impact target comet 9P/Tempel 1 obtained at and in the nights surrounding the time of the spacecraft's impact. These observationsExpand
Gemini-N mid-IR observations of the dust properties of the ejecta excavated from Comet 9P/Tempel 1 during Deep Impact
Abstract We present mid-infrared spectra and images from the Gemini-N (+MICHELLE) observational campaign of Comet 9P/Tempel 1 before, during, and after its encounter with Deep Impact. We use ourExpand
Deep Impact: Observations from a Worldwide Earth-Based Campaign
Data show that there was new material after impact that was compositionally different from that seen before impact, and the ratio of dust mass to gas mass in the ejecta was much larger than before impact. Expand
Comet 9P/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 theExpand

The Deep Impact mission delivered 19 gigajoules of kinetic energy to the nucleus of comet 9P/Tempel 1 on 4 July 2005. Intensive observations, both from the two spacecraft and from Earth andExpand
A large dust/ice ratio in the nucleus of comet 9P/Tempel 1
The Deep Impact mission shot a projectile into comet 9P/Tempel 1 in order to investigate its interior and reported the water vapour content and the cross-section of the dust created by the impact, suggesting that comets are ‘icy dirtball’ rather than ‘dirty snowballs’ as commonly believed. Expand
Deep Impact: Excavating Comet Tempel 1
A large increase in organic material occurred during and after the event, with smaller changes in carbon dioxide relative to water, and a thermal map indicates a surface in equilibrium with sunlight. Expand
The dust trail of comet 67P/Churyumov-Gerasimenko near aphelion
We present optical and infrared (24 μm) images of the dust trail of comet 67P/Churyumov-Gerasimenko near aphelion, obtained with the Wide Field Imager at the MPG/ESO 2.2m telescope in La Silla inExpand
