“…For the survival of a rover in the long phases of the cold lunar nights several methods are considered. These methods are to hibernate (Hashimoto et al, 2011), to use radioisotope thermoelectric generators (Bartlett et al, 2008), radioisotope heater units (RHUs), or to avoid prolonged shadows (Haarmann et al, 2012;Della Torre et al, 2010;Gump and Thornton, 2011). Methods to survive times of extremely high lunar surface temperatures include heat rejection via radiators or heat storage in phase change material.…”

“…Beside the recently landed Chinese Chang e3 mission, there is the planned Japanese SELENE-2 (Hashimoto et al, 2011), the Russian Luna-Glob (Luna-25), , and the Indian Chandrayan-2 (Goswami and Annadurai, 2011). In addition to governmental programs, there is an emerging private sector of Moon missions initiated through the Google Lunar X-Prize competition in 2010.…”

“…In 2011 NASA also sent Curiosity to explore the habitability of Mars [2]. The Japan Aerospace Exploration Agency (JAXA) is currently planning a mission to the moon called the SELENE-2 mission [3]. In this mission, rovers are expected to travel across wide open areas and observe terrain features using onboard scientific instruments.…”

a b s t r a c tIn this study, we propose a new attitude determination system, which we call Irradiancebased Attitude Determination (IRAD). IRAD employs the characteristics and geometry of solar panels. First, the sun vector is estimated using data from solar panels including current, voltage, temperature, and the normal vectors of each solar panel. Because these values are obtained using internal sensors, it is easy for rovers to provide redundancy for IRAD. The normal vectors are used to apply to various shapes of rovers. Second, using the gravity vector obtained from an accelerometer, the attitude of a rover is estimated using a three-axis attitude determination method. The effectiveness of IRAD is verified through numerical simulations and experiments that show IRAD can estimate all the attitude angles (roll, pitch, and yaw) within a few degrees of accuracy, which is adequate for planetary explorations.

“…Even though Mars has been regularly targeted by landers in the past 15 years (Ball et al, 2007), the Moon is turning out to be another popular target due to its proximity, which compresses the launch cycles and lowers the cost of missions whose main goal is developing advanced technologies with a view toward future mannedexploration. Today, no less than six space agencies worldwide have some dedicated lunar landing projects planned for the next ten years: The Japan Aerospace Exploration Agency (JAXA) (Hashimoto et al, 2011), the Indian Space Research Organization (ISRO) (Goswami and Annadurai, 2011), the China National Space Administration (CNSA) (Zheng et al, 2008), The Russian Federal Space Agency (RKA) (Mitrofanov et al, 2011), ESA (Fisackerly et al, 2012) and NASA (Ballard et al, 2012). The exotic distant worlds of the outer solar system are also relevant and coveted targets for robotic surface exploration.…”

a b s t r a c tThe potential for a nadir-looking radar sounder to retrieve significant surface roughness/permittivity information valuable for planetary landing site selection is demonstrated using data from an airborne survey of the Thwaites Glacier Catchment, West Antarctica using the High Capability Airborne Radar Sounder (HiCARS). The statistical method introduced by Grima et al. (2012. Icarus 220, 84-99. http://dx. doi.org/10.1007/s11214-012-9916-y) for surface characterization is applied systematically along the survey flights. The coherent and incoherent components of the surface signal, along with an internally generated confidence factor, are extracted and mapped in order to show how a radar sounder can be used as both a reflectometer and a scatterometer to identify regions of low surface roughness compatible with a planetary lander. These signal components are used with a backscattering model to produce a landing risk assessment map by considering the following surface properties: Root mean square (RMS) heights, RMS slopes, roughness homogeneity/stationarity over the landing ellipse, and soil porosity. Comparing these radar-derived surface properties with simultaneously acquired nadir-looking imagery and laser-altimetry validates this method. The ability to assess all of these parameters with an ice penetrating radar expands the demonstrated capability of a principle instrument in icy planet satellite science to include statistical reconnaissance of the surface roughness to identify suitable sites for a follow-on lander mission.
