Total posts from Mare 103 Search Tadpole and Lava Tube An irregularly shaped depression, resembling a tadpole (center left), which is part of a sinuous chain of pits. The black arrow indicates the beginning of the pit chain that trends to the southeast. This feature is about 8 km long and 600 m deep, and is located in the mare northwest of Gruithuisen crater. Color shaded-relief depicts elevation from NAC DTM PITVENT; higher elevations are red and white, lower elevations are blue and purple; north is up [NASA/GSFC/Arizona State University]. Published on 29 Aug 2014 Striped Crater Dark mantle deposits decorate a crater wall. 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 Littered Wrinkles LROC NAC image M1144863959L of portion of a wrinkle ridge found in Mare Nubium. The crest and side of the ridge is lined with high reflectance boulders, likely eroded from the fractured basalts that make up the ridge. Image width is ~3 km, North is up [NASA/GSFC/Arizona State University]. Published on 14 Aug 2014 Fresh, But Not So Clean LROC NAC image M131515002R showing two similarly sized craters, ~500 m in diameter, but one is littered with boulders and the other is not. This boulder discrepency is most likely due to age differences between the two craters. Image width is ~2 km, and North points up [NASA/GSFC/Arizona State University]. Published on 12 Aug 2014 A Tortuous Path in Posidonius This may look like a work of abstract art, but in reality, it's for science! This colorful image is an LROC slope map of the northwestern portion of the floor of Posidonius crater. Warmer colors indicate steeper slopes, whereas cooler colors are shallower slopes. A rille winds its way across the floor and flows along a southerly course, diverging from its path along the crater rim. A tributary rille can be seen joining the main rille at the bottom center. Image width is approximately 5.5 km. North is up [NASA/GSFC/Arizona State University]. Published on 31 Jul 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 A Rille to Rover Over LROC NAC image M1145219838 of a rille found on the Southwestern edge of Oceanus Procellarum. This rille most likely formed from the stress added to the crust as the mare deposits were emplaced and cooled [NASA/GSFC/Arizona State University]. Published on 08 Jul 2014 The Original Interplanetary Mountaineers Traverse plots of the first two Apollo 15 EVAs, on which astronauts Scott and Irwin ventured to the lower slopes of Mons Hadley Delta (center left); numbers indicate elevations above the landing site (LM) (oblique LROC NAC M1123519889; north is to the right). For scale, the dogleg distance the astronauts travelled from the LM to Elbow crater along the edge of Hadley Rille (EVA 1) is ~4.5 km [NASA/GSFC/Arizona State University]. Published on 20 Jun 2014 Rough Around the Edges With peppered flanks, Rima Suess wanders over 150 km through Oceanus Procellarum. The rocks that rest on the walls of this lunar rille are perhaps remnants of much larger boulders that have eroded down to meter sized rocks due to micro and macro meterorite bombardmet. LROC NAC image M168516400R has a width of ~400 m, and North points up [NASA/GSFC/Arizona State University].
