LunarLeaper is a mission concept designed to robotically explore subsurface lava tubes on the Moon. Lunar pits, steep-walled collapse features, are thought be connected such tube systems and more than 300 have been identified through remote sensing. These natural structures hold immense value for exploration scientific investigations, because they offer protection from radiation, micrometeorites, harsh temperature fluctuations lunr surface as such, proposed possible future human habitation....

Iceland is part of the accreting plate boundary between American and European plates. Since 1965 a number repeated triangulation‐trilateration surveys spanning neovolcanic zone in NE were made order to detect crustal movements. All measurements for single observation epoch are separately adjusted by method least squares. Statistical tests carried out check observations adjustment models outliers model errors. To significant movements repeatedly measured geodetic networks with multivariate...

Abstract Proton aurora are the most commonly observed yet least studied type of at Mars. In order to better understand physics and driving processes Martian proton aurora, we undertake a multi‐model comparison campaign. We compare results from four different proton/hydrogen precipitation models with unique abilities represent aurora: Jolitz model (3‐D Monte Carlo), Kallio Bisikalo/Shematovich et al. (1‐D kinetic Gronoff kinetic). This campaign is divided into two steps: an inter‐model...

Creating an absolute space-tie where all the geodetic methods are onboard is key for improved and stable terrestrial reference frame as well with various scientific applications. Such satellite concepts  have already been proposed to achieve accurate frame. Next generation  Galileo satellites can provide a single well-calibrated platform colocation of space-based techniques establishing precise ties between techniques.  One most crucial novel aspect such VLBI...

Lunar lava tubes are of significant interest for potential human exploration the Moon, therefore it is important to study their subsurface extent and physical properties in detail. The underground existence mare regions due past volcanic activity has been predicted (e.g. [1,2]) orbiting missions gravity surveys (GRAIL) radar investigations (Lunar Radar Sounder onboard SELENE) have identified candidate locations these structures [3-5]). But only global constraints could be inferred, because...
