The Indian Space Research Organisation (Isro) will launch the BlueBird Block-2 communications satellite for US company AST SpaceMobile today using its heavy-lift Launch Vehicle Mark-3 (LVM3). Weighing 6,100 kg, it will be the heaviest payload ever placed in low Earth orbit by the LVM3. The mission marks a milestone in Isro's commercial space efforts.
NASA and ISRO's NISAR satellite has detected over 2 centimeters of monthly subsidence in some Mexico City zones from October 2025 to January 2026. The phenomenon stems mainly from overexploitation of aquifers in the former Lake Texcoco bed. InSAR technology enables precise monitoring from space.

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.
