NASA reversed an evacuation order for astronauts aboard the International Space Station (ISS) after a worsening air leak prompted temporary sheltering in SpaceX Crew Dragon spacecraft. The agency and Russia’s Roscosmos examined the leak rate, with Roscosmos stating no immediate threat to the crew despite ongoing efforts to repair cracks in the Zvezda service module. This marked the first reversal of a safe-haven order in the ISS’s 27-year history.

A British Paralympian and surgeon could become the first person with a physical disability to live in orbit after the UK Space Agency signed a deal with US startup Vast for a mission to the Haven-1 space station. John McFall, part of the European Space Agency astronaut reserve, is cleared for orbital activities and may participate in the mission following the station's 2027 launch.

John McFall, a British ex-Paralympian, is set to become the first physically impaired person to live and work in space. He will travel to Germany to begin feasibility studies at the European Astronaut Centre with the European Space Agency.

NASA announced three Moon missions (Moon Base I, II, III) by 2026 to establish a permanent lunar base, using commercial landers from Blue Origin and Astrobotic to test technologies for sustained human presence and Mars exploration.

Japan’s Aerospace Exploration Agency (JAXA) and the European Space Agency (ESA) have confirmed the BepiColombo mission will arrive at Mercury on November 21, 2026, following a delayed schedule due to a thruster glitch. The mission, involving three spacecraft, aims to study Mercury’s interior and magnetosphere, marking humanity’s third mission to the planet.

Europe has developed a laser-equipped ground station in northern Greece to support secure and high-capacity satellite communications. The Holomondas Optical Ground Station will receive data from satellites via infrared laser links, providing higher throughput and security compared to traditional radio systems. This technology is expected to play a key role in future satellite constellations.

A coronal mass ejection captured by the ESA-NASA Solar and Heliospheric Observatory spacecraft increases the speed of space junk crashing to Earth. This event is related to solar activity. The crash of space junk to Earth is accelerated due to this phenomenon.

The European Union's Copernicus program has activated all four Sentinel-1 satellites, enhancing Earth observation capabilities. This expansion strengthens Europe's ability to monitor environmental changes and support disaster response efforts through advanced radar imaging.
