China's lunar rover discovers strange 'gel-like' substance with 'unusual colour' in crater on dark side of moon
A strange 'gel-like' substance has been discovered on the far side of the moon by a lunar rover sent by China's space agency.
The Yutu-2 rover, which landed on the far side of the moon in January of this year, found the substance last month but news of the discovery has just been made public.
The rover, part of China's Chang'e-4 lunar mission, discovered the substance in a crater just before it was set to power down for its usual midday 'nap'.
A team member looking at the rover's main camera spotted the small crater, which appeared to contain material with a colour unlike the surrounding lunar surface, Space.com reported.
Having seen the images, lunar scientists decided to postpone plans to send Yutu-2 further west and instead ordered the rover to check the strange material.
The rover, which is on the moon with the Chang'e-4 lunar probe, carefully approached the crater and then targeted the strangely-coloured material.
It was then that the scientists made the strange discovery, although they have so far only said that the substance was 'gel-like' and an 'unusual colour'.
One possible theory which was suggested by researchers not involved with the mission is that the substance is melted glass created from meteorites striking the surface of the moon.
China's space agency previously said the current mission 'lifted the mysterious veil' from the far side of the moon, which is never seen from Earth, and 'opened a new chapter in human lunar exploration'.
Because the space craft is solar powered, it has to switch off during a lunar night on the moon, during which there will be no sunlight.
The temperature on a lunar night is about -180°C (-292°F) and can get high during the day, where 'insulating' components like the gold coloured layers outside the lander and rover keep them cool.

Take samples and bring them to Earth, what could possibly go wrong

Well you might have trouble finding a stick, actually.

If China brings it back you can be certain it will eventually be polluting our air and water.

Anyone remember The Blob with Steve McQueen , but on another subject why are we still sending financial aid to China when they have the spare cash to do things like this

Just imagine what could be accomplished if China and the USA worked together to explore space.
Pete Freans, Meh, United States, 22 hours ago
There will be a Chinese military base up and running within the year.

It needs to be iIIegal to build on the near side of the moon. Once destroyed, the moon's wilderness beauty will never be restored.

At least they are more forthcoming about discoveries, unlike NASA - Never A Straight Answer.

It'll just be some cr@p leaking out of the lander itself. Made in China afterall.
