European researchers say they have created a process that can produce oxygen from moon dust. The process could provide a major source of oxygen for humans taking part in moon exploration activities in the future. Researchers from the European Space Agency（ESA）carried out the experiments and reported their results in a study.

The team says ESA’s experimental “plant” was able to successfully produce oxygen from simulated moon dust. The dust is part of a material known as regolith, which holds about 45 percent oxygen. However, the oxygen’s form is very strange, so it is hard to produce.

ESA’s long -term goal is to design an oxygen -producing “pilot plant” to work fulltime on the moon. Beth Lomax of the University of Glasgow was a lead researcher on the project. “Being able to get oxygen from resources found on the moon would certainly be hugely useful for future lunar settlers,” she said.

The researchers reported that the process also produced some usable metal materials. ESA researcher Alexandre said the finding that a number of metals are left behind was an important discovery.

ESA and the U. S. space agency NASA are both working on plans to return human beings to the moon. NASA has set a goal for 2024, with the aim to keep humans on the moon for long periods.

Dear Jack,

Thank you very much for your picture. I’m very glad to hear that you are having a good trip in my home town. London is very beautiful at this time of year. And the weather is cool. I hope I can go back there. It’s quite hot at this time of year in New York. I really need to relax myself during the holiday. I want to go swimming in the sea. I also want to visit your home town. My uncle works there. And his daughter Alice will come back from Washington DC. So we can spend our holiday together. It’s a good idea to take the train there. There is much traffic on the roads during holidays and driving is very dangerous. You said there’s a hill and a river in your home town. My sister Linda and I want to climb the hill and go fishing. I’m sure we’ll have a good time.

Yours,

Dave
