"Your robot is really something..."
Although the Chang'e 4 project was a joint effort between two companies, Shen Zuozhou couldn't help but criticize upon seeing the Explorer robot.
For the space agency, the purpose of Chang'e 4 was originally to continue the Chang'e 3 mission, and there wasn't much difference in the level of technology or mission content. However, due to New Yuan's intervention, it underwent some radical modifications.
The lander's weight reached 2.8 tons, more than double the originally planned 1.2 tons.
Thanks to the lander's weight, Lunar Rover 2 went from 135 kilograms to 150 kilograms, but it was still the world's smallest lunar rover...
Even the 420-kilogram Explorer robot seems small in comparison, as the previously launched "Lunar Rover 1" and "Lunar Rover 2" by the Union approached roughly 800 kilograms.
America's lunar rover was 210 kilograms, but that was made for astronauts on the Apollo mission.
