Colonization of Venus
Venus's atmosphere is made mostly out of carbon dioxide, which, after filtering from sulfuric acid, can be used to grow food. Because nitrogen and oxygen are lighter than the carbon-dioxide that makes the atmosphere, breathable-air-filled balloons will float at a height of about . At this height, the temperature is a manageable ; or if we could get higher (see ).
CubeSat UV Experiment
The Venusian upper cloud deck, situated at an altitude range 60-70 km, is formed of small droplets comprising a mix of ~80% sulfuric acid () and water. About half of the solar energy received by Venus is absorbed in the UV by a still
unknown absorber situated at the top of the cloud layer. Because of its vast absorbing power, knowing its nature is very important to understand the overall radiative and thermal balance of the planet and the atmospheric dynamics. Although NASA, Roscosmos, the European Space Agency, and Japan's JAXA have dispatched multiple missions to Venus, the nature of the cloud top absorber has not been established.
