Sonar equations for planetary exploration [PDF]

The Journal of the Acoustical Society of America, 2016
The set of formulations commonly known as “the sonar equations” have for many decades been used to quantify the performance of sonar systems in terms of their ability to detect and localize objects submerged in seawater. The efficacy of the sonar equations, with individual terms evaluated in decibels, is well established in Earth's oceans.

Mobile manipulation for planetary exploration [PDF]

2018 IEEE Aerospace Conference, 2018
Robotic systems map unknown terrain and collect scientific relevant data of foreign planets. Currently, pilots from Earth steer these rovers on Moon and Mars surfaces via teleoperation. However, remote control suffers from a high delay of the long distance communication which leads to a reduction of the time the rover can spent gathering scientific ...

SPEX: the spectropolarimeter for planetary exploration [PDF]

SPIE Proceedings, 2010
We present SPEX, the Spectropolarimeter for Planetary Exploration, which is a compact, robust and low-mass spectropolarimeter designed to operate from an orbiting or in situ platform. Its purpose is to simultaneously measure the radiance and the state (degree and angle) of linear polarization of sunlight that has been scattered in a planetary ...

Peak-ring structure and kinematics from a multi-disciplinary study of the Schrödinger impact basin

Nature Communications, 2016
Impact basins on the Moon are considered as the best landing sites for the recovery of information about the lunar interior. To inform future lunar missions, Kringet al.

Path Planning for Reconfigurable Rovers in Planetary Exploration [PDF]

, 2017
This paper introduces a path planning algorithm that takes into consideration different locomotion modes in a wheeled reconfigurable rover. Power consumption and traction are estimated by means of simplified dynamics models for each locomotion mode ...

Effects of dust layers on thermal emission from airless bodies

Progress in Earth and Planetary Science, 2019
We have investigated the influence of thin thermally opaque dust layers on the thermal emission of rocks and regolith and determined the thermal response of these dust-covered surfaces to diurnal insolation cycles.

Exploring Planetary Atmospheres

Eos, Transactions American Geophysical Union, 2013
The past decade has been an exciting time to study atmospheres. Fundamental studies of Earth's general circulation and hydrological cycle have been stimulated by questions about past climates and the future impacts of humankind's activities. Long‐term spacecraft and Earth‐based observations of solar system planets have reinvigorated the study of ...

Sun-synchronous planetary exploration [PDF]

Space 2000 Conference and Exposition, 2000
Contemporary planetary missions are characterized by favorable landing sites, communication, and duration. The ambition of planetary exploration is to discover the unknown: to explore regions, not just sites; to analyze, not just observe; and to operate effectively and reliably without excessive communication and ground support.
