LEAP - Legged Exploration of the Aristarchus Plateau

Autor: Patrick Bambach, Valentin Bickel, Hendrik Kolvenbach, Giorgio Valsecchi, Harald Steininger, Nicholas Eaton, Harald Hiesinger, Manish Patel

Mobile robotic surface platforms are critical for the exploration of the solar system. In the past, robotic ex-plorers were limited by their abilities to navigate and traverse challenging terrain, such as boulder fields andslopes steeper than 15°. T

Investigating the Effect of Perchlorate on Flight-like Gas Chromatography-Mass Spectrometry as Performed by MOMA on board the ExoMars 2020 Rover

Autor: Walter Goetz, Harald Steininger, Volker Thiel, Helge Mißbach

Publikováno v: Astrobiology. 19(11)

The Mars Organic Molecule Analyzer (MOMA) instrument on board ESA's ExoMars 2020 rover will be essential in the search for organic matter. MOMA applies gas chromatography-mass spectrometry (GC-MS) techniques that rely on thermal volatilization. Probl

Carbonization in Titan Tholins: implication for low albedo on surfaces of Centaurs and trans-Neptunian objects

Autor: Chaitanya Giri, Fred Goesmann, Nadine Schäfer, Joachim Reitner, Xiang Li, William B. Brinckerhoff, Harald Steininger, Thomas Gautier, Uwe J. Meierhenrich, Christopher P. McKay

Publikováno v: International Journal of Astrobiology. 15:231-238

Astronomical observations of Centaurs and trans-Neptunian objects (TNOs) yield two characteristic features – near-infrared (NIR) reflectance and low geometric albedo. The first feature apparently originates due to complex organic material on their
