China Is Planning To Land, And Grow Plants On, The "Dark" Side Of The Moon This Year

There are a lot of exciting space missions to look forward to in 2018, from the inaugural launch of SpaceX’s Falcon Heavy to a return to Mercury. But China might be planning one of the most exciting missions of all – the first-ever landing on the far side of the Moon.
Called Chang’e 4, the mission will be China’s fourth to the Moon, following two orbiters in 2007 and 2010, and a rover in 2013. There have been plenty of other proposals to land on the far side of the Moon, not least from the US and Russia, but none have materialized.

“The Chinese are pushing back the frontier with such a technically challenging mission,” space analyst Brian Harvey told The Guardian.
The mission will entail two parts. The first, possibly launching in June this year, will be a relay satellite placed into lunar orbit. As the far side is blocked from Earth’s view, a relay satellite is needed in order to transmit communications between the surface and our planet. Then, by the end of the year, we might see the landing take place.
Chang’e 4 was designed as a backup to Chang’e 3, the partially successful lander and rover (called Jade Rabbit) that landed on the near side of the Moon in 2013. Chang’e 4 will be similar, comprising also a lander and a rover. While the exact specifics of the mission aren’t clear yet, we do know how it might make the most of the unique opportunity.
The Moon is tidally locked to our planet, so one of its faces always points towards us. This means we never see the far side – often incorrectly called the “dark side”, although both sides of the Moon reveal equal amounts of light as it orbits Earth.
But it is dark in a sense, in that radio signals from Earth are blocked from reaching the far side. If you were to place a radio telescope on the far side of the Moon, well, you’d get a rather incredible uninterrupted view of the cosmos. Chang’e 4 may include such a telescope, although that’s not clear at the moment.
What’s more clear is that the lander will probably include a small ecosystem, to attempt the growth of plants and insects on the lunar surface. This will include potatoes and silkworm eggs, and the event is set to be live-streamed for the public back on Earth to watch.
China’s ultimate goal is to land humans on the Moon, possibly in the 2030s. They also have plans to return a sample as early as 2019. Chang'e 4 could be an important step towards those goals.
