NASA crewmembers at the International Space Station will return to Earth within days due to a health issue affecting an astronaut.

The unidentified crewmember is stable following the medical event.

Carnegie researcher Luke Bouma is investigating how stellar particles shape planetary environments and potential habitability using a plasma structure around certain young M dwarf stars.

M dwarf stars are smaller, cooler, and dimmer than the Sun and commonly host at least one Earth-sized rocky planet.

A team of astronomers discovered 19 super- and ultra-fast-rotating asteroids.

About 1900 of the observed asteroids were confirmed as never-before-seen.

The Vera C. Rubin Observatory observed thousands of asteroids in the Solar System during the NSF-DOE First Look event in June 2025.

One of the discovered asteroids is the fastest-spinning asteroid larger than 500 meters.

V1298 Tau is a star approximately 20 million years old.

The planets in the V1298 Tau system have close-in orbits.

The V1298 Tau system offers insights into a dynamic stage of planetary evolution.

The V1298 Tau system hosts four planets between the sizes of Neptune and Jupiter.

Astronomers have identified a young planetary system named V1298 Tau.

In emergencies, geostationary, medium Earth orbit, and low Earth orbit satellites could function as space-based computing centers while ground stations handle high-demand or less time-sensitive computing tasks.

A central design challenge for Space-CPN is creating communication principles that support specific computation tasks instead of simply maximizing raw data throughput.

The robust information bottleneck principle highlighted for Space-CPN seeks to maximize mutual information between the computed result and the true label of a data sample to maintain accuracy while minimizing mutual information between the extracted feature and the input sample to improve compression.

Space-CPN extends terrestrial computing power networks into space by integrating the communication and computation capabilities of low Earth orbit, medium Earth orbit, and geostationary Earth orbit satellites.

Superradiance can cause rapid energy loss in quantum systems, creating challenges for quantum technologies.

Superradiance is a cooperative phenomenon where quantum particles work together to produce signals stronger than any individual particle could generate.

A study published in Nature Physics suggests that superradiance can also generate self-sustained, long-lived signals.

Chinese astronauts and ground-based science teams completed 86 new scientific and technological tasks on the Tiangong space station in 2025.

In 2025, a total of 1,179 kilograms of experimental instruments, materials, and other necessities for science and technology missions were sent to the Tiangong space station.

The China Manned Space Agency reports that the Tiangong space station's role in research is expanding.

The positioning technology by Trimble will deliver centimeter-level accuracy in challenging conditions such as tunnels, parking structures, and dense urban corridors.

The positioning system combines Trimble RTX corrections with the ProPoint Go positioning engine.

Trimble has agreed to provide positioning technology for the Lucid Gravity electric vehicle.

The award includes four missions for the National Reconnaissance Office (NRO).

Two of the missions are for the Tranche 2 Tracking Layer (T2TR) with Lockheed Martin satellites scheduled for Q2 2027.

The United States Space Force (USSF) has awarded nine missions to SpaceX under the National Security Space Launch (NSSL) Phase 3 Lane 1.

Two of the missions are for T2TR with L3Harris satellites scheduled for 2027.

One of the missions is for the Space Development Agency's (SDA) FOO Fighter scheduled for Q3 2026.

ESA has previously met its CSOC obligations through cargo transportation services using the Automated Transfer Vehicle and service modules for NASA’s Orion spacecraft.

In May 2024, ESA awarded Phase 1 contracts to The Exploration Company and Thales Alenia Space Italia for the LEO Cargo Return Services initiative.

Member States committed to serving as an anchor customer for four additional flights following the successful completion of the demonstration missions.

Northrop Grumman’s Cygnus spacecraft emerged as the most likely option for the cargo transport services.

ESA has outlined a revised barter arrangement with NASA to meet its CSOC obligations.

ESA will publish a new call for proposals for industry to deliver on the new barter agreement.

Under the CSOC framework, all ISS partners share the responsibility for the station’s general upkeep, including cargo and crew transportation.

Phase 2 includes provisions for two providers to conduct demonstration missions to the ISS by mid 2029.

During the Ministerial Council meeting in November 2025, ESA Member States committed to fully funding Phase 2 of the LEO Cargo Return Services initiative.

Daniel Neuenschwander outlined a revised barter arrangement during a press conference following ESA Director General Josef Aschbacher’s annual briefing on 8 January.

The new barter scheme reduces the requirement for commercial transportation services and introduces the use of LEO Cargo Return Services.

ESA announced its LEO Cargo Return Services initiative in May 2023 to foster the development of a commercially operated European spacecraft for cargo transportation to and from low Earth orbit.

ESA cancelled the cargo transport services call on 17 December, citing 'the implementation of programmatic adjustments.'

The European Space Agency (ESA) cancelled a call for proposals in December for a commercial cargo mission to the International Space Station (ISS) related to the station’s Common System Operations Costs (CSOC).

ESA required the delivery of up to 5,000 kilograms of pressurized cargo by 2028.

The United States will allow Europe to deliver LEO cargo return services as part of the ISS cooperation.

In October 2025, ESA published a call for commercial cargo transport services to the ISS to meet its CSOC obligations.

The E4D machine will allow for a wide variety of movements and will work all muscle groups.

Sophie Adenot will conduct scientific and medical experiments and contribute to the operations and maintenance of the ISS during her mission.
