Assigned ID: 244 ----- Submission 1 (Thu Jan 22 20:58:52 GMT 2004) ----- The Gas Environment of Comet 9P/Tempel 1 During the Deep Impact Encounter This program consists of a series of observations of periodic comet 9P/Tempel 1 in conjunction with NASA's Deep Impact mission. This mission is a spacecraft that will release a 360 kg impactor into the nucleus of the comet on July 4, 2005. Our primary objective is to study the generation and evolution of the gaseous coma resulting from this impact. We had planned to obtain ultraviolet spectra with STIS before, during, and following the impact. A secondary objective was to obtain wide-band images of the visual outburst resulting from the impact. With STIS now unavailable, the requisite images can be taken with the ACS/HRC. In addition, the spectroscopic data can be obtained using two of the prism modes of the ACS; HRC/PR200L can replace STIS/G230L and SBC/PR130L can replace G140L.
The primary objective of this program will be to observe comet 9P/Tempel 1 at the time of the Deep Impact mission delivery of the impactor to the surface of the comet. This event occurs on July 4, 2005. For measurements of the evolution of the gaseous coma, we require 13 orbits. These will be performed in visits of contiguous orbits on 4 separate days: prior to impact within one rotation period (42 hours) (4 orbits); impact (or as close as possible in time - 5 orbits); one day after impact (2 orbits); and one week after impact (2 orbits). Each orbit, with the exception of the impact orbit, will consist of both images and prism spectra, alternating HRC and SBC cameras to cover the entire ultraviolet spectral range. The impact orbit will consist solely of HRC imaging, which will give us the highest spatial resolution images of the comet possible from Earth. At the time of impact, which is one day before perihelion, the comet will have a heliocentric distance, r, of 1.506 AU, and a geocentric distance, Delta, of 0.894 AU. Based on previous apparitions, the total V magnitude will be ~10 while the nuclear V magnitude, based on an estimated effective radius of 2.5-3.0 km, will be between 17 and 18. From the ACS Exposure Time Calculator, for V=17.5 the full well of the HRC CCD will be reached in an exposure time of 390 seconds. At this time it is not possible to assess the brightness of any jets that may be present. However, jets or coma structure with surface brightness 10^-4 per pixel of the nucleus will easily be detectable above the sky background and detector dark levels. As described above, these observations are being coordinated with and need to be made at the time of the active phase of the Deep Impact mission in early July 2005.
