The Mars Aerobot Micromission is almost a factor of 10 smaller than earlier concepts for a Mars balloon. A key goal is to achieve high payload mass fraction in a small total systems mass and to maximize the scientific potential of that payload. Scientific objectives include studies of the surface with a high resolution stereo imaging magnetometer and investigations of the structure and dynamics of the atmosphere with an in situ meteorology payload.

A mission to return a sample to Earth from the surface of Venus faces a multitude of multidisciplinary challenges. In addition to the complications inherent in any sample return mission, Venus presents the additional difficulties of a deep gravity well essentially equivalent to Earth's and a hot-house atmosphere which generates extremes of high temperature, density, and pressure unmatched at any other known surface in the solar system. The Jet Propulsion Laboratory of the California Institute of Technology recently conducted a study to develop an architecture for such a mission; a major goal of this study was to identify technology developments which would need to be pursued in order to make such a mission feasible at a cost much less than estimated in previous. The final design of this mission is years away but the study results presented here show our current mission architecture as it applies to a particular mission opportunity, give a summary of the engineering and science trades which were made in the process of developing it, and identify the main technology development efforts needed.
