Slowly pulled downhill by gravity, the volcanic glasses that compose these stripes where formed during explosive volcanic eruptions on the Moon. The scene is 952m wide from NAC image M1101259668L; north is up [NASA/GSFC/Arizona State University]. Published on 25 Aug 2014 Frozen Motion The scoured floor of Harkhebi J crater, near the young crater Giordano Bruno (22 km diameter). Ejecta from Giordano Bruno flowed across the surface, leaving a record for us to see today. LROC NAC image M1128791817L; north is up and the scene is 1.2 km wide [NASA/GSFC/Arizona State University]. Published on 20 Aug 2014 Dorsum Nicol This tectonic feature was formed as stresses built up in the lunar crust until the rock gave way. The energy released was immense, and the displaced rock is the north-south trending wrinkle ridge that we see today. This is LROC NAC image M1105773947LR with a slope map overlaid, warmer colors in the image represent steeper slopes. Image is 4765 m wide; north is up [NASA/GSFC/Arizona State University]. Published on 17 Jul 2014 Birt E Birt E crater is thought to be the source region for lava that carved out Rima Birt, a rille in Mare Nubium. This mare is older than 3.4 billion years, and so is this vent! LROC NAC M1144849711LR with the a color DTM overlaid; North is up, and image width is ~3 km [NASA/GSFC/Arizona State University]. Published on 15 Jul 2014 Eroding Crater Walls High reflectance material poured down the walls toward the floor of Maskelyne B crater indicating interbedding of high reflectance and low reflectance layers in the walls. Image width is 2800 m and vertical relief is 1300 m (4250 feet). North is up; LROC NAC mosaic M137360167 [NASA/GSFC/Arizona State University]. Published on 30 May 2014 Displaying all 5 Post
