   Oct 1, 2023 · A unique aspect of Venus is the significant amount of solar energy available at the top of the atmosphere, since Venus orbits the Sun at a distance of 0.72 astronomical unit (AU). At this location, the solar irradiance is ∼2622 W/m 2. This is approximately twice the solar irradiance at Air Mass 0 (AM0) above the Earth's atmosphere, at ∼1367 ...

   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.

   Apr 10, 2019 · Power beaming (also known as wireless energy transfer) is a means for transmitting electrical energy through various media (i.e., vacuum, air, water) via electromagnetic energy. 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 ...

   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 ...

   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.

   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.

   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.

   How much solar energy does Venus absorb?

   • Due to its high albedo the planet absorbs only 157 ± 6 W/m 2 on average, less than that deposited on Earth ( ≈ 240 W/m 2), despite the fact that Venus is 30 % closer to the Sun. Both models and observations show that less than 10 % of the total solar energy incident on Venus reaches the surface, and only 2.5 % is absorbed there.

   Why does Venus absorb less solar energy than Earth?

   • The strongly scattering clouds reflect more than 75 % of incoming solar flux back to space, so that Venus absorbs less solar energy than the Earth does, even though it is 30 % closer to the Sun.

   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 1, 2012 · The radiative energy balance in the Venusian atmosphere was described in Sect. 4.3. Figure 4.16 shows a sketch of the global mean budgets of energy and entropy on the planet. At the cloud level Venus receives ≈ 400 mW/m 2 /K of entropy from solar radiation and looses ≈ 600 mW/m 2 /K from thermal emission.
