    An inspection spacecraft prepares to visit inactive satellites

    The Small Spacecraft Propulsion and Inspection Capability mission launched on Oct. 1, 2026, from Vandenberg Space Force Base in California. Built by Starfish Space, the Otter spacecraft will approach up to four inoperable U.S. space objects in low Earth orbit to perform inspections using autonomous guidance and control software. Scheduled to begin in early 2027, the technology demonstration aims to gather critical data on inoperable satellites and rocket bodies without docking, paving the way for future autonomous orbital servicing and debris removal.

    Solar wind particles reveal the origin of a magnetic kink

    Solar Orbiter has traced a large S-shaped magnetic kink in the solar wind back to the Sun. Its Solar Wind Analyser detected charged oxygen and carbon particles with signatures of hot magnetic loops near the solar surface. The measurements support interchange reconnection as the origin of this switchback, while waves and turbulence appear to influence its later movement through space. Studying both stages could help researchers better understand the solar wind and the space weather that affects satellites and Earth.

    A giant Martian cloud hints at an unusual way to make ice

    A new model using Mars Express observations suggests that the long cloud beside the Arsia Mons volcano may form without dust particles helping ice crystals grow. In the proposed process, called homogeneous nucleation, water vapour freezes directly into ice under unusually humid conditions. Winds flowing past the roughly 20-kilometre-high volcano could create those conditions by lifting and rapidly cooling moist air. The model reproduces much of the observed cloud, although some details still differ, so the explanation remains a strong inference.
