Korea’s Innospace announced it has postponed the launch of the Hanbit-Nano rocket, originally scheduled for Wednesday (Dec. 17), to Friday at 3:45 pm. It would have been the first time a commercial flight departed from a Brazilian base. 

According to a statement, the company changed the launch date to allow sufficient time to “replace components after detecting an anomaly in the cooling device of the first stage oxidizer supply system during the final inspection.”

The Brazilian Air Force, which operates the Alcântara Launch Center in Maranhão state, confirmed the postponement.

The space vehicle – which is 21.8 m long, 1.4 m in diameter, and weighs 20 tons – was scheduled to go into space on Wednesday, carrying satellites into low Earth orbit at an altitude of some 300 km and an inclination of 40 degrees.
