Die Indian Space Research Organisation (Isro) wird heute den Kommunikationssatelliten BlueBird Block-2 für das US-Unternehmen AST SpaceMobile mit ihrem Schwerlastträger Launch Vehicle Mark-3 (LVM3) starten. Mit 6.100 kg wird es die schwerste Nutzlast, die je vom LVM3 in einen niedrigen Erdorbit gebracht wurde. Die Mission markiert einen Meilenstein in Isros kommerziellen Raumaktivitäten.
NASA's Van Allen Probe A satellite, launched in 2012 to study Earth's radiation belts, is set to reenter the atmosphere early this week after running out of fuel in 2019. The agency has approved a safety waiver due to the reentry's risk exceeding government standards, though the chance of harm remains low at 1 in 4,200. Most of the 1,323-pound spacecraft will burn up, with some debris potentially reaching the surface.

Chinese researchers have developed a storm nowcasting system using satellite data and AI techniques, enabling effective convection forecasts up to four hours in advance. The breakthrough, published in the Proceedings of the National Academy of Sciences, was achieved jointly by Wang Jingsong from the National Satellite Meteorological Center and researchers from various universities and institutes.
