Performance characteristics of lithium-ion cells for Mars Sample Return Athena Rover
In this paper, we will present several performance characterization tests, including cycle life at different temperatures, rate capability at various charge/discharge rates and temperatures and real tim and accelerated storage, which were carried out on these prototype cells in support of the Mars exploration missions.
Recent Observations of the Heliospheric Magnetic Field at Ulysses: Return to Low Latitude
Ulysses recently completed a second slow latitude scan of the northern heliosphere, a descent from 80.2 degrees North in July 1995 to the solar equator in December 1997.
MARS Orbiter Sample Return Power Design
This paper considers the aspect and conclusion that went into the design of the power system that achieves the maximum power with the minimum risk. The power output for the spherical orbiting canister was modeled and plotted in various views of the orbit by the Satellite Orbit Analysis Program (SOAP).
Technologies for Mars Exploration and Sample Return
A comprehensive program of robotic Mars exploration is being undertaken in order to address important scientific questions, to investigate whether or not life exists or ever existed on Mars, and to pave the way for eventual human prescence.
