Lunar Biosphere Bucket Frozen as Planned and Plants are Dead

The plants on the moon are now dead. The Chang’e-4 probe entered a sleep mode on Sunday as the first lunar night after the probe’s landing started. The temperature could drop as low as about minus 170 degrees centigrade. Life in the biosphere canister would not survive the lunar night.

A moon-day is 28.5 Earth-days long. A moon night is about 14 days long.
