NIAC 2019 Phase I Power Beaming for Long Life Venus Surface Missions. Fig. 22. a) Variable temperature EQE measurements of a GaInP (dash line)/GaAs (solid line) 2 junction solar cell between 25 and 300°C [17] and b) Bandgap of GaAs between 25 and 465°C. Above 300°C, the bandgap was extrapolated.
Apr 10, 2019 · NIAC 2019 Phase I Brandon Powerbeaming. A new approach to support long duration Venus surface missions will be investigated, which will address the difficult challenge of surface power generation in such an extreme environment. The key mission concept centers on the use of a dual vehicle architecture—one vehicle is a high altitude platform ...
Oct 1, 2023 · Brandhorst [21] noted microwave and laser power beaming at Venus are not possible due to the nature of the geostationary orbit radius. Since the Venus geostationary orbit radius is 1.536 × 10 6 km and the Hill Sphere for Venus is ∼1.0042 × 10 6 km, a geostationary orbit at Venus is not stable and to achieve any semblance of synchrony with the surface, a Lagrange Point orbit is required ...
Jul 7, 2023 · “Counterintuitively, power beaming via laser sources may be possible at Venus despite the continuous cloud coverage, given certain optical/infrared “windows” present within the Venus ...
This study analyzes the possible power systems for a Venus surface mission. III. Power System Study This study analyzes the possible power systems for a lander on the surface of Venus that will survive for at least 1 Venus solar day. Previous studies have analyzed the use of a radioisotope power system (RPS) for use on the surface of

ACHIEVING LONG LIFE ON THE SURFACE OF VENUS. Approaches to date use large vessels/thermal mass and thermal management techniques to maximize life – best to date ~127mins. −Can accomplish a lot of science, but inherently time limited. Another approach: design a cooled lander – requires a lot of power. Cooled Lander Concept.
