Previous research found that lunar soil possesses a number of elements vital for plant growth. This has raised hopes that greenhouse farms on the moon could make use of local resources to help lunar bases sustain life, instead of astronauts having to lug huge amounts of soil or bulky hydroponic systems from Earth.

"The advantage of growing plants on the moon is not limited to providing food for the astronauts who live in the lunar base," study lead author Yitong Xia, of China Agricultural University in Beijing, told Space.com. "It could also help to refresh the air by providing oxygen, purify water and even provide emotional comfort."

Modern Science dismissed such as mere legends, of course. Right up until they discovered one in the shipwreck of the Alderney, an Elizabethian warship that sank in 1592. Although she sailed well beyond the times of the Vikings she did sail in the time before all the vagrancies of magnetic navigation were mastered. The Sunstone was found with the Navigation equipment, & is believed to have been used to correct or back up the magnetic navigation devices.

Although the sands & chemical reactions had clouded the Sunstone, they were able to determine that it was a piece of Icelandic Spar. One of the optical properties of Icelandic Spar is it actually doubles the objects passing through it.*" (ibid)
