A pair of European satellites have created the first artificial solar eclipses through precise and fancy formation flying.

The magnetic field drives the formation of sunspots, cooler regions on the solar surface that appear as dark blotches. At the ...

Scientists have constructed the first complete proton energy spectrum observed during an eruptive solar event in Martian space, deepening our understanding of the radiation environment around Mars.

What does an artificial eclipse look like? One space agency's satellites recently accomplished this task as part of a mission ...

My firm, Space Solar, has designed a solar-power satellite called CASSIOPeiA, which is more than twice as powerful – based on the key metric of power per unit mass – as ESA’s design. So far, we have ...

Like nuclear fusion, the idea of space-based solar power has always seemed like a futuristic technology with an actual deployment into communities ever remaining a couple of decades away.

Researchers in China have investigated how transparent smart radiation devices (TSRD) can be used to protect space solar cells from extreme thermal fluctuations. Through a series of simulations ...

Eventually, Space Solar hopes to build Eagle, a 1.4-kilometer-wide spacecraft in geostationary orbit that would beam 600 megawatts of continuous solar power to the ground.

A history of space-based solar power. Isaac Asimov first suggested SBSP in a 1941 short story. Peter Glaser described the concept formally in a Science paper in 1968.

UK startup Space Solar has reached an agreement with Reykjavik Energy with a view to supplying 30 MW from space-based solar in 2030. Co-CEO Sam Adlen tells pv magazine the next steps include ...
