Just 24 hours after releasing photographs of the first ever plants grown on the moon, China has revealed the tender green shoots are now all dead.

The cotton plants had been the only seeds to sprout inside their aluminium container, known as a “moon surface micro-ecological circle”, which cost more than 10 million yuan (£1.15m). But the probe is now in lunar night, and temperatures have fallen too low for life to survive.

The Chang’e-4 probe, which landed on the far-side of the moon on 3 January, apparently entered “sleep mode” on Sunday as the first lunar night after the probe’s landing fell, Professor Xie Gengxin, chief designer of the experiment, told China’s Xinhua state news agency.

“Life in the canister would not survive the lunar night,” Professor Xie said.

It is not clear why, if the Chinese space agency knew the falling of the lunar night would kill the plants on Sunday, their death was not announced along with the successful germination of the seeds on Tuesday.

Other reports have suggested the pod was supposed to last three months and create a self-sustaining environment for life away from our planet.

The South China Morning Post even said the China National Space Administration planned to broadcast such an experiment in “less than a hundred days’ time”.

The moon lander was carrying soil, cotton seeds, rock cress, rapeseed and potato seeds, yeast and fruit fly eggs.

On Tuesday Professor Liu Hanlong of Chongqing University, who led the research, said the rapeseed and potato seeds had also germinated, but the cotton seeds were first to sprout, according to the South China Morning Post.

“We have given consideration to future survival in space. Learning about these plants’ growth in a low-gravity environment would allow us to lay the foundation for our future establishment of space base,” Mr Liu said.

The report gave no indication the plants had already all died.

A Super Blue Blood Moon is the result of three lunar phenomena happening all at once: not only is it the second full moon in January, but the moon will also be close to its nearest point to Earth on its orbit, and be totally eclipsed by the Earth's shadow. The last time these events coincided was in 1866, 152 years ago.

Picture date: Wednesday January 31, 2018. Blue Moons are defined as the second full moon in a calendar month. And this one will also be a supermoon, meaning the Earth's natural satellite will appear about 14% bigger and 30% brighter in the sky as it reaches its closest point to Earth.

It also said the 3kg aluminium container was designed to maintain a temperature of between 1 and 30 degrees, allow in natural light and feed the plants with water and a nutrient solution.

It did not add that when lunar night fell, its contents would all be killed.
