It was constructed at a cost of $4 Billion and will provide the electricity needs of 14 million Egyptians.
NASA has asked the private sector to design new spacesuits that can be used on the Moon.
He said that three main requirements should be fulfilled to improve the cooling effect. The radiative coolers should not replace the existing PV glass covers, so the natural RC ability of glass can be harnessed to add to the overall cooling gain. There should also be an efficient and quick heat transfer mechanism between the PV module, which is also the heat source, and the RC heat sink. In addition, the RC module should directly face the sky to radiate maximum waste heat into outer space.
The proposed system consists of a PV module and a separate RC module, integrated with a flat plate heat pipe in between. A separate RC module is used along with the existing glass cover on the solar cells and the heat pipe is integrated between the PV and RC modules, providing quick heat transfer. The RC module is then placed on the condensing section of the heat pipe facing the sky.

I have often mentioned how useful it would be to relocate an asteroid to lunar orbit to serve as a counterweight for a rotovator / skyhook.
Data from NSF’s NOIRLab Show Earth Trojan Asteroid Is the Largest Found The SOAR Telescope, part of NOIRLab’s Cerro Tololo Inter-American Observatory, has helped astronomers refine the size and orbit of the largest known Earth Trojan companion. By scanning the sky very close to the horizon at sunrise, the SOAR Telescope in Chile, part of Cerro-Tololo Inter-American Observatory, a Program of NSF’s NOIRLab, has helped astronomers confirm the existence of only the second-known Earth Trojan asteroid and reveals that it is over a kilometer wide — about three times larger than the first.
When archaeologists first glimpsed the gilded splendor of King Tutankhamun’s tomb, they never thought that one of the most fascinating artifacts didn’t originate in Egypt — or on Earth.
Tutankhamun ascended the throne at 9 and died at 19. While he may not have reigned long, he did wield an iron dagger that was (in the most literal sense) out of this world. It might have not looked like much compared to all the riches unearthed from his tomb, including a gold death mask that seems to gaze into the hereafter, but the blade of this dagger was actually carved from a meteorite that had previously fallen to Earth. The question is where that dagger was forged.
Never mind the origin of the asteroid that burned up in the atmosphere and sent a meteorite hurtling to Earth. Where the dagger itself came from is debatable, but the type of space rock it was made from might have now revealed something. Researcher Tomoko Arai of the Chiba Institute of Technology in Japan looked up close to find out what type of meteorite was used for such a weapon. She coauthored a study recently published in Meteoritics and Planetary Science.
HP appears to be strengthening its position as a provider of XR software for enterprise companies. Today it announced the release of a mobile device management (MDM) solution that’s designed to make deploying and managing large-scale VR easier.
Called HP ExtendXR, the software as a service (SaaS) was built in collaboration with ArborXR, an AR/VR device management company that came out of the VR arcade space in 2016.
HP says its collaboration with ArborXR is targeting companies who want to more easily scale their VR deployments, but also take advantage of HP’s global support and HP Horizon secure cloud infrastructure.
Austin is home to many of the players in the new space race, like CEO Shey Sabripour, whose startup just raised tens of millions to make satellite-based communications more efficient.
