Collapse features on Ascraeus Mons (THEMIS_IOTD_20170905)
This image shows part of the northeastern flank of Ascraeus Mons, along the trend that joins the three large Tharsis volcanoes. The image has a myriad of collapse features from circular to linear outlines. The majority of the collapse features don't interact with the surface lava flows, indicating that the collapse features were formed after the main emplacement of lava flows from the summit and near summit vents.
NASA's Mars Odyssey spacecraft has spent over 15 years in orbit around Mars, circling the planet more than 69,000 times. It holds the record for longest working spacecraft at Mars. THEMIS, the IR/VIS camera system, has collected data for the entire mission and provides images covering all seasons and lighting conditions.
Over the years many features of interest have received repeated imaging, building up a suite of images covering the entire feature. From the deepest chasma to the tallest volcano, individual dunes inside craters and dune fields that encircle the north pole, channels carved by water and lava, and a variety of other feature, THEMIS has imaged them all.
For the next several months the image of the day will focus on the Tharsis volcanoes, the various chasmata of Valles Marineris, and the major dunes fields. We hope you enjoy these images!
