"2025: Japanese Satellite to Transmit Solar Power to Earth"

Originally Published 1 year ago — by Space.com

Japan is set to launch a small satellite in 2025 to demonstrate the transmission of solar power from space to Earth, marking a significant step towards a potential space-based solar power station. The satellite will wirelessly transmit energy from low Earth orbit using a photovoltaic panel and microwaves, with the mission part of a project called OHISAMA. While the concept of space-based solar power was once considered impractical and costly, recent technological advances and the urgency to decarbonize the world's power supply have renewed interest in the idea, although some challenges and concerns remain.

Revolutionary Membrane Mirrors for Space Telescopes

Originally Published 2 years ago — by Phys.org

Researchers have developed a new method to produce and shape large, high-quality mirrors that are much thinner than the primary mirrors previously used for telescopes deployed in space. The mirrors are flexible enough to be rolled up and stored compactly inside a launch vehicle. The researchers used chemical vapor deposition to grow membrane mirrors on a rotating liquid inside a vacuum chamber, which allowed them to form parabolic thin membranes that can be used as the primary mirror of a telescope once coated with a reflecting surface such as aluminum. The new membrane-based mirrors could also be used in adaptive optics systems.
