We studied a Mars sample return (MSR) mission that lands a SpaceX Dragon Capsule on Mars carrying sample collection hardware (an arm, drill, or small rover) and a spacecraft stack consisting of a Mars Ascent Vehicle (MAV) and Earth Return Vehicle (ERV) that collectively carry the sample container from Mars back to Earth orbit.
Missions to the surface of Venus have had limitedlife due to the extreme environmental conditions. Theshort life has limited the science that is achievable,and there are gaps in some science, such asseismology, which is enabled by long life. This worksummarizes technical advances that are preparing usfor long-duration (weeks to months) Venus surfacemissions.
Testing conducted verified that the thruster could indeed be fired with catalyst bed temperatures.
NASA requires lightweight rechargable batteries for future missions to Mars and the outer planets that are capable of operating over a wide range of temperatures, with high specific energy and energy densities.
