   Oct 1, 2023 · The Venus solar intensity as a function of altitude is discussed in Ref. [49] and the expected power from a Venus optimized solar cell as a function of altitude is presented in Ref. [20]. Short wavelength and high-power lasers in the visible and near infrared coupled with high efficiency laser power converters (LPCs) derived from commercially available photovoltaic cells could enable power ...

   2.2.2 Solar Arrays . The solar spectrum in the Venus atmosphere is different from that on Earth and varies significantly with altitude. Absorption and scattering by the atmosphere and thick cloud structure [12] reduces the intensity from ~2622 W/m. 2 . above the atmosphere to <100 W/m. 2 . at the surface.

   May 3, 2021 · A study published today confirms that Venus’ upper atmosphere undergoes puzzling changes over a solar cycle, the Sun’s 11-year activity cycle. This marks the latest clue to untangling how and why Venus and Earth are so different. Born of similar processes, Earth and Venus are twins: both rocky, and of similar size and structure.

   Apr 10, 2019 · In this case, a transmitter located on an atmospheric platform (power generation side) would beam power to a receiver (lander energy storage) through the carbon dioxide atmosphere. For a Venus mission, this would require transmitting power at radio frequency (rf) or microwave wavelengths, due to the presence of extensive cloud cover that would block optical/laser based power transfer methods.

   Aug 16, 2017 · Venus has intrigued planetary scientists for decades because of its huge contrasts to Earth, in spite of its nickname of “Earth’s Twin”. Its invisible upper atmosphere and space environment are also part of the larger story of Venus and its evolution. In 60s to 70s, several missions (Venera and Mariner series) explored Venus-solar wind interaction regions. They identified the basic ...

   Can solar power beam through the Venus atmosphere?

   • The usual methods— solar power, batteries, radioisotope thermoelectric generators—aren't up to the task. That's according to new research titled, "Feasibility of power beaming through the Venus Atmosphere," published in the journal Acta Astronautica. The corresponding author is Erik Brandon from the Jet Propulsion Laboratory.

   How much solar energy does Venus have?

   • Credit: Grandidier et al. 2023 Venus is closer to the sun, but its thick atmosphere means not much solar radiation reaches the surface. About 75% of the sun's energy is reflected by Venus' clouds, and only about 2.5% of the solar flux incident at the top of the atmosphere reaches the surface. Up above the clouds, solar energy is abundant.

   Is a solar array a viable option above the Venus atmosphere?

   • 3. Conclusion Despite the abundant power above the Venus atmosphere, and an ability to deploy very large solar arrays in space, absorption and scattering in the Venus atmosphere is too high to make standard power beaming architectures from an orbiter to the surface a viable option, in both the microwave and optical frequency ranges.

   Is power beaming possible at Venus?

   • 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 atmosphere, which are not available using microwave power beaming.

   Could solar energy be used to power surface probes on Venus?

   • Eventually, we might be able to beam energy from solar satellites down to Earth, making solar energy available almost anywhere and helping combat climate change. But there's another potential use: powering surface probes on Venus. Everybody knows about Venus. It's killed multiple landers with its extreme heat and crushing atmospheric pressure.

   Jan 26, 2021 · The coupling efficiency of the energy transfer from the solar wind to the Venusian O + ion escape is calculated as the ratio between the total power available in the solar wind P SW and the total power escaping from Venus P Q. The available power in the solar wind is calculated as the energy flux F SW, energy times the area A SW over which the ...
