Spacecraft Imaging for Amateurs an International Community of Space
Planetary Close-ups emily lakdawalla Spacecraft Imaging for Amateurs An international community of space This is Mars’s Big Sky Country, a windswept, nearly featureless plain. Tiny ripples in the rust-colored sand march farther than the eye can see, to a horizon so fl at one might be able to see the curvature of the planet. As far as anyone knows, those ripples have not budged in eons. But all is not still; gaze upward, and you might be surprised by the rapid motion overhead, where feathery cirrus clouds, frosty with bright crystals of water ice, fl oat on high Martian winds. The scene is from Meridiani Planum, composed from eight images captured by the Mars Exploration Rover Opportunity just before she reached a deep crater named Victoria, on the 950th Martian day of her mission. But the beautiful image was not created by anyone on the Mars Exploration Rover team; no scientist would likely have Earthbound produced it, because it owes its beauty as much to art as it observers never does to science. see Mars as a The image is the collaborative creation of a whole crescent, but amateur-imagesmith community; six people, each from spacecraft do. a diff erent country, had a hand in it.

Most of the fractures are located 33 on the crater floors. The floor-fractures are concentric, radial or polygonal and share similarities with 34 Class 1 and 4 floor-fractured craters (FFC) on the Moon (e.g., Buczkowski et al., 2018; Schultz, 1976) 35 In total we measured 2336 fractures in thirteen craters. -

PAC Chair, Dr. Anne Verbiscer, welcomed everyone to the virtual meeting. Announcements were made around the table and on Webex. PSD Status Report Dr. Lori Glaze, Director of the Planetary Science Division, gave a status report. First addressing the President’s Budget Request (PBR) for Fiscal Year 2021 (FY21) for the Science Mission Directorate (SMD), Dr. Glaze noted that it was one of the strongest science budgets in NASA history, representing a 12% increase over the enacted FY20 budget. The total PBR keeps NASA on track to land on the Moon by 2024; and to help prepare for human exploration at Mars.
