After nearly a week's journey by sea, China's new-generation Long March-7 rocket has arrived at a launch base in the southern island of Hainan.

Since its arrival, staff members have been assembling parts and conducting tests in preparation for its launch in late June. The rocket uses liquid propellant, which makes it more environmentally friendly than previous modules.

The Long March-7 will transport cargo for China's planned space station, and is expected to become a main carrier for future space launches.
