Moon rich ground for mining: Experts

WASHINGTON: Moon is a rich ground for mining, with an estimated 1.6 billion tonnes of water ice at its poles and an abundance of rare-earth elements hidden below the lunar surface, experts say.

Private firms and space agencies are dreaming of tapping into these lucrative resources and turning the Moon's grey, barren landscape into a money-making conveyer belt, according to an article published in the journal Physics World.

Since NASA disbanded its manned Apollo missions to the Moon over 40 years ago, unmanned spaceflight has made giant strides and has identified a bountiful supply of water ice at the north and south poles of the Moon.

"It is this, more than anything else that has kindled interest in mining the Moon, for where there is ice, there is fuel," science writer Richard Corfield wrote in the article.

Texas-based Shackleton Energy Company (SEC) plans to mine the vast reserves of water ice and convert it into rocket propellant in the form of hydrogen and oxygen, which would then be sold to space partners in low Earth orbit.

As the company's chief executive officer, Dale Tietz, explains, the plan is to build a "gas station in space" in which rocket propellant will be sold at prices significantly lower than the cost of sending fuel from Earth.

SEC plans to extract the water ice by sending humans and robots to mine the lunar poles, and then use some of the converted products to power mining hoppers, lunar rovers and life support for its own activities.

Moon Express, another privately funded lunar-resources company, is also interested in using water ice as fuel - but in a different form, according to the article.

It plans to fuel its operations and spacecraft using "high-test peroxide" (HTP), which has a long and illustrious history as a propellant.

"As for mining the rare-earth elements on the Moon, China is making the most noticeable headway," the article said.

The Jade Rabbit lander successfully touched down on the Moon in December 2013 and the Chinese space agency has publicly suggested establishing a base on the Moon.

With a near-monopoly on the dwindling terrestrial rare-earth elements, which are vital for everything from mobile phones to computers and car batteries, it is no surprise that China may want to cast its net wider, the article said.
