U.K. to strengthen regulations for Starlink, OneWeb and other NGSO constellations

TAMPA, Fla. — British telecoms regulator Ofcom is proposing rule changes that would affect Starlink, OneWeb and other satellite constellations operating in non-geostationary orbits (NGSO). It is increasingly difficult for companies to agree on how to operate their NGSO networks without causing harmful radio interference to each other, Ofcom warned in a July 26 consultation…

Op-ed | It’s time to seriously consider space-based solar power

In the late 1960s, enterprising scientist Peter Glaser proposed using orbiting satellites to collect incoming solar radiation, transform it into microwaves, and beam it down to focused receivers on Earth where it would be converted into electricity. Although space-based solar power (SBSP) sounds like science fiction, scientists and engineers have explored developing the futuristic technology…

Asteroid the size of the Great Pyramid of Giza just flew (safely) by Earth

An asteroid about as long as the Great Pyramid of Giza is tall made a “close” approach with Earth on Sunday (July 25), according to NASA calculations. There is no worry that the space rock poses any threat to Earth, but NASA monitors such rocks to both learn more about the early solar system — asteroids are rocky…

The United States is about to take its next giant leap into space – the return of U.S. astronauts to the moon by 2024, this time to stay.  As the final step in landing astronauts on the moon, the Human Landing System (HLS) will play a significant role in the success of the Artemis program.…

Neutron star 'mountains' may be blocking our view of mysterious gravitational waves

Neutron stars are covered with “mountains” only fractions of a millimeter tall, new research shows, meaning these bumps are hundreds of times smaller than previous estimates had suggested. Neutron stars are compact stellar objects, similar in size to a large city with a diameter of around 6.2 miles (10 kilometers), that weigh at least 1.4…

Russia discards Pirs docking port to clear way for new space station module
