Meter-scale slopes of candidate MER landing sites from point photoclinometry
Photoclinometry was used to analyze the small-scale roughness of areas that fall within the proposed Mars Exploration Rover (MER) 2003 landing ellipses. The landing ellipses presented in this study were those in Athabasca Valles, Elysium Planitia, Eos Chasma, Gusev Crater, Isidis Planitia, Melas Chasma, and Meridiani Planum. We were able to constrain surface slopes on length scales comparable t...
متن کاملTopography of Candidate Phoenix Landing Sites from Moc Images
Introduction: This abstract continues our series of reports [1-3] on high-resolution topographic mapping of martian terrains based on stereo and photoclinometric analysis of Mars Global Surveyor Mars Orbiter Camera narrow-angle (MGS MOC-NA) images [4]. Our initial efforts [1,2,5] were devoted to quantifying the topographic and slope hazards of candidate landing sites for the Mars Exploration Ro...
متن کاملTen-meter Scale Topography and Roughness of Mars Exploration Rovers Landing Sites and Martian Polar Regions
Introduction The Mars Orbiter Camera (MOC) has been operating on board of the Mars Global Surveyor (MGS) spacecraft since 1998. It consists of three cameras Red and Blue Wide Angle cameras (FOV=140 deg.) and Narrow Angle camera (FOV=0.44 deg.). The Wide Angle camera allows surface resolution down to 230 m/pixel and the Narrow Angle camera down to 1.5 m/pixel. This work is a continuation of the ...
متن کاملMars Exploration Rover candidate landing sites as viewed by THEMIS
The analysis of six landing sites that were candidates for the two NASA Mars Exploration Rovers (MER) benefited from recently available image data from the Thermal Emission Imaging Spectrometer (THEMIS) onboard the 2001 Mars Odyssey spacecraft. The combination of daytime and nighttime thermal infrared images from THEMIS supplemented by additional data sets has lead to new or expanded insights i...
متن کاملAutonomous landing at unprepared sites by a full-scale helicopter
Helicopters are valuable since they can land at unprepared sites; however, current unmanned helicopters are unable to select or validate landing zones (LZs) and approach paths. For operation in unknown terrain it is necessary to assess the safety of a LZ. In this paper, we describe a lidar-based perception system that enables a full-scale autonomous helicopter to identify and land in previously...
