Supercritical CO? could eliminate some of rocketry's most expensive infrastructure requirementsCold launches avoid exposing launch pads to destructive exhaust temperatures exceeding 3,000°CEngine ignition occurs only after the rocket clears the launch platform safelyChinese aerospace startup Z-Trak Space is exploring an unusual launch system using carbon dioxide (CO?) commonly associated with fizzy drinks rather than rocket exhaust.The proposal centres on supercritical CO?, a state achieved when the gas remains above specific temperature and pressure thresholds simultaneously.Developers believe the approach could lower infrastructure requirements while supporting faster launch schedules for China's expanding commercial space sector.Latest Videos FromA cold launch system could reduce…
