NASA has opened the door to the next generation of space discovery by announcing great plans for a base for humans to live on the surface of the moon forever.
The project to build a base on the moon will begin soon after 2020, with astronauts living there within four years.
The project comes after several excellent scientists and environmentalists asked humans to look beyond Earth to ensure the survival of the species (物种).
Eventually, the moon will be a base for humans to explore the solar system and one day land on Mars.
NASA began planning for the first moon landing since 1972 when George Bush, the US president, announced his new plan for space exploration four years ago.
NASA has already talked about the design of the Orion spacecraft that will replace the old space shuttle fleet in 2010.
The plan for the moon base, however, is the first detailed explanation of how NASA intends to prepare for the first manned exploration of deep space and a possible Mars mission within 30 years.
Scientists also believe that the south pole on the moon contain rich natural gases such as the rare helium-3 that could be used as fuel for the generation of nuclear power. Besides, teams of astronauts living there for six months at a time would mine for hydrogen and oxygen to make water and possibly rocket fuel.

They leap from helicopters or speeding boats, bringing aid to swimmers who get into trouble off Italy’s popular beaches.
For these dog lifeguards, the doggie paddle （狗刨式游法）does just fine.
These “lifedogs” tow a buoy(救生衣) that victims can grab, or a raft they can sit on to be towed back to shore, and unlike their human counterparts(与对方地位相当的人), they can easily jump from helicopters and speeding boats to reach swimmers in trouble.
With millions flocking(人群) to Italy’s crowded beaches each summer, the Italian Coast Guard says it rescues about 3,000 people every year — and their dog helpers are credited with saving several lives.
It takes three years for the canines to reach expert rescue status, and currently 300 dogs are fully trained for duty, said Roberto Gasbarri, who co-ordinates the Italian School of Canine Lifeguards program at a centre outside of Rome in the seaside town of Civitavecchia.
“Dogs are useful in containing the physical fatigue（疲劳） of the lifeguard, to increase the speed at which casualties（遇难者） are retrieved（找到并衔回）, to increase the security of both the casualty and of the lifeguard,” Gasbarri said.
The Civitavecchia centre is one of a dozen around the country for the school founded more than 20 years ago in the northern province of Bergamo by Ferruccio Pilenga, whose first trainee was his own Newfoundland.
The school will train any breed（品种）, as long as they weigh at least 30 kilograms, but Labradors, Newfoundlands and golden retrievers are most commonly used because of their natural instinct for swimming. Each dog works in tandem with（同 ……合作） a human lifeguard, who also acts as the animal’s trainer.
