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 ...

Ryugu’s observed volatile loss did not arise from impact heating alone

Communications Earth & Environment, 2021
The loss of volatile material from asteroid Ryugu was not caused solely by heating from hypervelocity impacts as previously believed, suggest impact experiments conducted at speeds comparable to those expected in the main asteroid ...

Insights into the formation and evolution of extraterrestrial amino acids from the asteroid Ryugu

Nature Communications, 2023
Amino acid concentrations from 2 particles returned from different touchdown sites on the surface of Ryugu are reported. Differences in chemistry suggest different levels of aqueous alteration are recorded at the 2 sampled locations.

Terrain Modelling for Planetary Exploration [PDF]

Fourth Canadian Conference on Computer and Robot Vision (CRV '07), 2007
The success of NASA's Mars Exploration Rovers has demonstrated the important benefits that mobility adds to planetary exploration. Very soon, mission requirements will impose that planetary exploration rovers drive autonomously in unknown terrain. This will require an evolution of the methods and technologies currently used.

Path Planning for Planetary Exploration [PDF]

2008 Canadian Conference on Computer and Robot Vision, 2008
In this paper we present the work done at the Canadian Space Agency on the problem of planetary exploration. One of the main goals is the over-the-horizon navigation of a mobile robot on a Mars like environment. A key component is the ability to plan a path using maps of different resolutions and also to refine/replan when more data becomes available ...
