Live TV broadcast for launch of HTV-3 CubeSats

FSpace, the team of young engineers and students at the FPT University who developed the amateur radio F-1 CubeSat, report on the final launch preparations for the HTV-3 cargo vessel that will carry five CubeSats to the International Space Station (ISS).

FSpace say final inspection was performed on July 9, and from July 13-15, a rehearsal was conducted simulating the launch operation. Late access cargo loading will continue until July 19 then the hatch will be closed and the H-IIB launch vehicle with the HTV-3 will be moved to the launch pad. The launch is planned for July 21 at 02:18 UT.
