Delacourt Universite´ Claude Bernard Lyon-1 & ENS Lyon, Laboratoire Sciences de la Terre, UMR 5570 CNRS, Bat ge´ode-6e e´tage, 2 rue Raphae¨l Dubois, 69622 Villeurbanne Cedex, France The walls of the Valles Marineris canyons are affected by about 45 landslides. The study of these landslides provides a test of the hypothesis of processes having affected Martian wallslopes after their formation. The dynamics of Valles Marineris landslides are controversial : either the landslides are interpreted as large debris flows or as dry rock avalanches. Their morphology and their topography are basic parameters to understand their dynamics. From topographic MOLA data and remote sensing images acquired with different spatial resolutions (Viking, THEMIS, MOC), the 3D geometry of 45 landslides of Valles Marineris has been studied. -

The Open University | watch?v=SK5tPzHHW50 [MUSIC PLAYING] KAREN FOLEY: So Jan Raack, welcome to the studio. What do you think of our audience's ideas? Aren't they creative? JAN RAACK: Of course, yes. So I joined the online chat a couple of minutes. KAREN FOLEY: I hear you've doing very well. JAN RAACK: Yeah, it was my first time-- KAREN FOLEY: Bringing some sense to the conversation, I hear. JAN RAACK: A little bit of science, yes, but not so much. Yes. KAREN FOLEY: No, that's brilliant. No, thank you. What's it like then for you? You're an academic at the Open University. You've been here not since very long. So you started here in March so it's all been quite new. What's it been like talking with-- and we've got a lot of science students out there. What's it been like as an academic then talking to everybody in this sort of environment? How have you found it? JAN RAACK: A little bit weird, to be honest, because I was a student a couple of years ago, too. And for me, it's a step further from students to ask questions-- to answer questions. So for me, it's really new and I am excited with it, really, and I enjoyed it. Yes. KAREN FOLEY: Excellent. You're now doing a lot of research. So you were from Germany and you've now come to the Open University here in sunny Milton Keynes. JAN RAACK: Sunny, yes. KAREN FOLEY: Well, not really, is it? We won't lie. -

The year 2019 was rich in impressive scientific results, but also in innovative importance application of social and economic works. Using the observations of neutral interstellar helium from the NASA IBEX-Lo space experiment, the density of He+ ions in the closest interstellar environment of the Sun was determined and the degree of ionization of helium, hydrogen and electron density in this medium was measured. -

Results We studied the mineralogy, geomorphology and Sulfates were observed in the valleys north, east and layering attitude of Light Toned Deposits (LTD) in south of Ophir Mensa and partly within Ophir Mensa Ophir Chasma, Mars, using visible and short wave itself. The southern slope of Ophir Mensa, exposed in infrared data (SWIR) from the imaging spectrometers the informally named "mineral bowl" valley [4], OMEGA and CRISM together with panchromatic shows spectra of monohydrated sulfates (MHS) and and color imagery, digital elevation models and partly polyhydrated sulfates (PHS). The slope is anaglyphs from HRSC, Themis, CTX, MOC and heavily eroded, suggesting that the sulfates are found HiRISE.

In addition, the power supply of the In- Sight instruments is provided by solar arrays. Solar-powered missions on Mars like the Sojourner rover in 1997 were af- fected by a decline in electrical power output by 0.2-0.3 % per day caused by steadily dust deposition on its horizontal Fig. 2.
