Target MARS-OPPOSITION-2016: There is no need or capability to test the scheduling of observations of moving targets in Phase I. This warning will go away the next time the proposal is loaded.This Cycle 23 Heritage DD submission supersedes an earlier version which was accidentally submitted as a Cycle 24 proposal (#8). - Max Mutchler1108286036Assigned ID: 16

----- Attempting Submission 2 (Tue Apr 26 19:08:13 GMT 2016) -----hedging on post-flashHubble Heritage imaging of Mars opposition 2016The Hubble Heritage Team proposes observe Mars with WFC3 around the time of opposition in May 2016, in order to produce images for a public release and also high-quality archival data for scientific analysis.We propose to observe Mars near opposition, which occurs on 22 May 2016, to obtain WFC3/UVIS multi-color imaging. Mars will be near the Earth evenly illuminated by the Sun, which is ideal for our observations. It will also be easily visible to the public in the nighttime sky. At opposition, Mars will be at a distance of 0.51 AU, and its disk will subtend a diameter of 18.4 arcsec. Within our one HST orbit, we will sweep through a set of four WFC3 filters (F275W, F410M, F502N, F673N) several times each, and include a small dither shift, to mitigate cosmic rays and detector artifacts. Mars will easily fit within the 1K subarray, which will minimize CTE effects and allow us to obtain over 20 exposures per orbit. We hedge a bit with exposure timess for each filter, since it is difficult to know in advance which Mars features might be prominent at the time of the observation (e.g. polar caps, clouds). Exposure times will generally be short, but some may saturate in spots, and we also use post-flash for some of the shotest exposures. We obtained approval to specify BLADE=A for all exposures to mitigate shutter-driven vibrations. The Hubble Heritage team imaged Mars at opposition in 2007 with WFPC2 (HST program 11361). We used filters F410M, F502N, and F673N. In this proposal we have included a wide UV filter (F275W) which also does not require very long exposures times and could reveal interesting Martian cloud structure. Opposition will be near the end of the aphelion cloud belt season, which was originally discovered using HST. We would like to schedule this observation a week or so before the opposition date, so the public release can coincide with the opposition.Solar System3AVAILABLESOLAR SYSTEMYESPLANETMars just before opposition 2016STD=MARSEARTHWFC3/UVISImagingNoNoF275WWFC3/UVISImagingNoNoF410MWFC3/UVISImagingNoNoF502NWFC3/UVISImagingNoNoF673NWFC3/UVISImagingNoNoF275WWFC3/UVISImagingNoNoF410MWFC3/UVISImagingNoNoF502NWFC3/UVISImagingNoNoF673NWFC3/UVISImagingNoNoF275WWFC3/UVISImagingNoNoF410MWFC3/UVISImagingNoNoF502NWFC3/UVISImagingNoNoF673NWFC3/UVISImagingNoNoF275WWFC3/UVISImagingNoNoF410MWFC3/UVISImagingNoNoF502NWFC3/UVISImagingNoNoF673N/private/var/folders/tj/27ygn_756lz3w1z19s6wtgtm0006vh/T/OPVisit8439721162104051196.xmlUsing ephemeris for target 14499-01-MARS-OPPOSITION-2016ephemeris data for target 14499-01-MARS-OPPOSITION-2016 does not cover planning interval.
