Asteroid near Earth detected hours after it passed the planet
International space agencies say an asteroid zipped by Earth closer than a large number of satellites currently in orbit, but was not detected until hours later.
The European Space Agency said Monday that a 3- to 10-foot-wide asteroid was picked up by radar last Wednesday some 265 miles above Earth over Antarctica, near Earth's most southern point, at an altitude similar to that of the Space Ocean and Space Nukes Forge Alliance to Develop Deep Space Power Systems
Space Ocean Corp, a leader in orbital logistics and in-space resource delivery, has signed a Letter of Intent (LOI) with Space Nuclear Power Corporation (Space Nukes) to explore the integration of advanced nuclear reactor technology into future deep-space missions.
The collaboration centers on testing Space Nukes' 10-kilowatt nuclear reactor aboard Space Ocean's ALV-N satellite. Upon meeti AST SpaceMobile and Verizon Partner to Deliver Space-Based Cellular Service Across the U.S.
AST SpaceMobile, Inc. (NASDAQ: ASTS), the company building the first and only space-based cellular broadband network directly accessible by standard smartphones, has signed a definitive commercial agreement with Verizon (NYSE, NASDAQ: VZ) to deliver direct-to-cellular service for Verizon customers beginning in 2026. The partnership aims to extend Verizon's award-winning network with space-based Completed Plato spacecraft is ready for final tests
By fitting its sunshield and solar panels, engineers have completed the construction of Plato, the European Space Agency’s mission to discover Earth-like exoplanets. Plato is on track for the final key tests to confirm that it is fit for launch.

Satellites reveal the power of ocean swell
During recent storms, satellites recorded ocean waves averaging nearly 20 metres high – as tall as the Arc de Triomphe in Paris and the largest ever measured from space. Moreover, satellite data now reveal that ocean swells act as storm ‘messengers’: even though a storm may never make landfall, its swell can travel vast distances and bring destructive energy to distant coastlines.
Rehearsing for Sentinel-6B’s early days in space
Last month, mission controllers at ESA's mission control centre started a major simulations exercise to ensure that the next Copernicus Sentinel Earth Observation mission, Sentinel-6B, safely navigates its first days in space. As the launch is approaching, so is the end of this critical pre-launch phase.
