What is Hydrosat Osiris Thermal Imaging Constellation?

Remote sensing means gathering information about the Earth without touching it, for example from satellites. According to Hydrosat, in thermal imaging from space, observers have had to choose between fine detail over small areas and broad coverage that lacks enough detail to act on. Osiris is a planned constellation of Earth observation satellites that images surface heat in thermal infrared light, aiming to combine both. Hydrosat announced it on 16 September 2026; the satellites are planned to capture imagery at 25-meter resolution over strips of ground (called swaths) 160 to 340 kilometers wide, with the first two scheduled to launch in 2027.
