Receipt: # 15456-2 ----- Attempting Submission 3 (Wed May 16 19:26:58 GMT 2018) ----- ----- Attempting Submission 4 (Mon Jun 18 19:50:03 GMT 2018) ----- ----- Attempting Submission 5 (Tue Jun 19 15:20:44 GMT 2018) ----- We ask for permission to specify BLADE=A. We propose to image Mars with WFC3 near opposition, which occurs on 27 July 2018. This program essentially repeats the same observations conducted for the Mars 2016 opposition (HST program 14499), and is also intended to produce images for public release and archival research. We propose to observe Mars near opposition, which occurs on 27 July 2018, 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. 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 times 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, a nearly global dust storm is underway in June 2018, and may persist through our observations in July). Exposure times will generally be short, but some may saturate in spots. We will not use post-flash which might increase the chance of saturation, and we feel the bright halo of Mars (overlapping PSF wings off the disk) will adequately fill charge traps during CCD readout. We seek approval to specify BLADE=A for all exposures to mitigate shutter-driven vibrations. We have included a wide UV filter (F275W) which also does not require very long exposures times and could reveal interesting Martian cloud structure. We would like to schedule this observation a week or so before the opposition date, so the public release can coincide with the opposition.
