We expect the coordination of the relative timing of visits to fully cover Mars's surface to require some back and forth with our Program Coordinator since the separation between observations should be less than one day. 1294175591 Assigned ID: 5938 ----- Attempting Submission 1 (Mon Oct 07 19:10:02 GMT 2024) ----- FLASH level may be too low for this exposure or a short subexposure.

See extended explanation in the diagnostic browser This is the initial submission. This is actually a 3-orbit program, but visits 4-6 are a backup in case of pointing failures during visits 1-3. I tried to set them as ON HOLD but that may not be the right way to express this. We may add FLASH but we are reviewing whether it was helpful for our last Mars program. We expect to work closely with our Program Coordinator to find windows at the right intervals, realizing we may need to compromise on those timing constraints. -- Max Mutchler -296776831 ----- Attempting Submission 1 (Tue Oct 08 20:48:28 GMT 2024) ----- We are considering using FLASH. We propose to take UV and optical images of the full surface of Mars at opposition to track surface features and weather patterns as the planet rotates. Using filters F275W, F410M, F502N, and F673N will highlight cloud features only visible in UV and other surface features in optical light. We will obtain high signal-to-noise imaging of Mars at opposition in both UV and visible light, with the F275W, F410M, F502N, and F673N filters. We propose a single WFC3 pointing which will adequately cover the entire object. We will visit this target 3 times separated by 8.2 hours, in order to image the entire surface of Mars as the planet rotates. At opposition in January, 2025, Mars has a diameter of 15 arcsec, and the moons Phobos and Deimos will orbit well within 1 arcmin of the planet. Because Mars is so bright, we will use similar narrow and medium band filters as past observations both to limit exposures and to match the look and feel of previous opposition observations, allowing direct comparison over time. We will also include a UV filter to image the clouds of Mars and to demonstrate Hubbles unique UV capabilities. Within each 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. Exposure times will generally be short, but some exposures may still saturate in spots (e.g., bright cloudsthat cannot be predicted). 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 as close to opposition as possible, though in Reduced Gyro Mode, the window of visibility closes roughly 2 weeks before opposition. The visibility window for Mars near opposition is fairly brief. Due to the risk of guide star failure in the short time frame, we would like to schedule two sets of 3 visits each and cancel the second set upon the successful completion of the first. We therefore request 6 orbits for this program. Each visit within a set of 3 should be scheduled roughly 8.2 hours apart so that the planet surface can be imaged in its entirety. Observations should be as close to the Jan 18 opposition as possible. The team has a wealth of experience in making outreach images for the Hubble Space Telescope and is responsible for creating Hubble images viewed by billions of people world-wide, includingthe 31st, 32nd, 33rd, and 34th anniversary images which together were viewed over 3 billion times. The team includes decades of experience in writing Hubble news releases, designing informal educational and outreach products based on Hubble data, as well as instrument expertise specializing in treatment of WFC3 data.
