Two space companies have collaborated to demonstrate automated close approaches between spacecraft using a single camera as the primary sensor.

For two decades, ESA has sent a medical doctor to brave the cold and more for 13 months at Concordia station in Antarctica, one of the most remote places on Earth. This unique environment – isolated, confined and extreme – mirrors many of the psychological and physiological challenges astronauts face in space. By studying life at Concordia, scientists can better understand these effects, develop countermeasures and prepare for future human missions beyond Earth. 

Satellites are emerging as a powerful new tool in the fight to curb emissions of methane. While methane is much shorter-lived in the atmosphere than carbon dioxide, it is vastly more potent at trapping heat, which makes rapid cuts essential for slowing warming in the short term. The same satellite technology that has transformed methane monitoring in the oil and gas sector is now being turned towards another major source – landfill sites.

NASA engineers are continuing efforts to restore contact with the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter after the spacecraft fell silent during a routine pass behind Mars on December 6 2025. Before the loss of signal, telemetry from MAVEN indicated that the spacecraft and its subsystems were operating within expected parameters as it approached occultation by the planet. A
