NASA's ACS3 solar sail launched on April 24 via Rocket Lab's Electron and on Aug. 29, NASA verified the technology had fully deployed in space

NASA’s solar sail successfully spreads its wings in space

More than four months after launching to space, a solar-sailing spacecraft has successfully spread its wings above our planet.

NASA’s Advanced Composite Solar Sail System (ACS3) caught a ride to space on April 24 on Rocket Lab’s Electron vehicle and, at the end of August, NASA shared in a release that its mission operators verified the technology reached full deployment in space. On Thursday, Aug. 29 at 1:33 p.m. EDT (5:33 UTC), the team obtained data indicating the test of the sail-hoisting boom system was a success.

Instead of collecting the sun’s energy on the ground, it may be possible to harvest it in space using satellites.

NASA lays out the path to space-based solar power

,

A new NASA report found that space-based solar power — a futuristic concept pulled from the pages of science fiction — is likely too expensive to work, but it also lays out exactly what would need to change to make it a viable source of clean energy in the future.

The challenge: Solar power is a revolutionary weapon in the battle against climate change. Every hour, enough solar energy hits Earth to power the entire world for a year, and the cost of harnessing this energy with solar panels has fallen exponentially in recent years.

NASA plans to reexamine the feasibility of space-based solar power, an approach that is finding new support based on lower launch costs, technological advances and interest in clean energy sources.

NASA to reexamine space-based solar power

WASHINGTON — NASA is starting a study to reexamine the viability of space-based solar power, a long-touted solution to providing power from space that may be getting new interest thanks to technological advances and pushes for clean energy.

In a presentation at the National Space Society’s International Space Development Conference May 27, Nikolai Joseph of NASA’s Office of Technology, Policy and Strategy said the agency was beginning a short-term study evaluating the prospects of space-based solar power, or SBSP, the first by the agency in about two decades.

Repairing a solar array in space

Here on Earth, solar power is one of the ultimate sources of off-grid electricity. Unless you’re in the far north and don’t get sunlight half the year or you’re somewhere that’s frequently cloudy, it’s a very dependable source of electricity that can be used to charge batteries and power everything from a phone, to a small refrigerator ice chest, to a whole house or EV. So, it’s a great alternative.

In space, you have less of a choice. Even as close to earth as the International Space Station or China’s Tiangong Space Station, you can’t exactly drive to town to get more fuel for your trusty Honda generator. Not only are you always at least 250 miles from the nearest town, but getting things into earth orbit takes a lot of energy. Even if your old lawnmower-engined generator could work in space (it can’t run without oxygen), bringing fuel for the thing would be prohibitively expensive.
