After hitting a maximum speed of 10.5 km per second en route to the Moon, it will fire its rocket engines again, this time to decelerate and soft-land as the dawn breaks on Mare Imbrium, a vast lava plain on the Moon. ECA, the rover, will be released onto the surface to transmit high definition images to the spacecraft, which in turn, will transmit them to Earth.
The mission will be phased over 24 days in all—10 days in orbit and 14 days on the surface. The spacecraft is 600 kilograms in total and almost 2 metres tall. It will run on 240 watts of solar power and 28 volt 24 amp hour battery.
