Just over 8 Earth days. 212 hours in total.
This is what the first plant to germinate on the Moon lived with life.
The Chinese mission Chang & # 39; and 4 stopped watering the cotton lump, as planned by Chongqing University, which designed the experiment.
The plant lived on a special ship aboard the Chang & e; 4 spacecraft, which landed on the hidden side of the Moon on January 3.
The minibiosphere in which he grew up would not have survived the lunar night.
This is the phase where the Earth's satellite enters now and it assumes that temperatures can drop to around -170 degrees Celsius.
A single lunar night is equal to two weeks on Earth.
During this time, the entire Chinese mission will enter the "sleep mode" and their systems will be dormant to save energy.
For this reason, the plant was no longer irrigated and died, as planned.
The Chinese embankment also carries potato seeds and arabidopsis, a mustard family plant, as well as flies eggs and yeasts.
Temperatures within the ecosystem are expected to drop below 52 degrees Celsius, so the organisms will be "in a freezing state," the university said in a statement on Tuesday.
When temperatures start to rise next month, organisms may "slowly break down" into their sealed containers.
"Some of the results [de los experimentos] exceeded our expectations, "said experiment designer Xie Gengxin on Chinese state television.
Why are you important?
The ability to grow plants on the moon will be essential for long-term space missions such as trips to Mars that will take two and a half years to reach its destination.
That would mean that astronauts could potentially grow their own food in space, reducing the need to return to Earth for refueling.
"I think there is certainly a lot of interest in using the Moon as a scale, particularly for trips to Mars, because it is relatively close to Earth," Watson said.
