Yesterday, the Chinese cargo spacecraft Tianzhou 3 reached the Chinese space station’s Tianhe core module. It was launched about 6.5 hours earlier on a Long March-7 Y4 rocket from the Wenchang base. This is the second cargo spacecraft launched to the new Chinese space station and carries propellant along with supplies of various kinds for the taikonauts, as the Chinese call their astronauts, who will arrive in October.
