Life on Mars

Some people believe humans could live on the planet Mars by the year 2100. Our own planet, the Earth, is becoming more and more crowded and polluted because of the rapid increase in population.     1    (hopeful), people could start all over again and build     2     better world on Mars. Here is what life there could be like. At present, our spacecraft are very slow—it would take     3    (month). With the development of technology, the journey might only take about 20 minutes by 2100 in spacecraft     4     travel at the speed of light!     5    , the spacecraft would travel so fast that the journey might be quite     6     (comfort). Many people would feel ill. Humans cannot survive     7     water, oxygen or food. Nobody knows     8     there would be enough water or oxygen on Mars for people there. Gravity could be another problem. The gravity on Mars     9    (be) only about three-eighths of that on the Earth. People would have to wear boots that are specially designed to prevent     10     from floating off into space. Life on Mars would be interesting as well as challenging.

2 . Several recent studies examined how machine automation and artificial intelligence (AI) will change the future of work.

Some people predict these technologies could replace up to 30 percent of workers worldwide by 2030. The possibility of being replaced will greatly increase for workers with less education, said Price Waterhouse Coopers, an international company providing financial and tax services. It estimated(估计) that in Britain, up to 46 percent of workers without a college degree could be in danger because of automation. This would drop to about 12 percent for workers with undergraduate degrees or higher.

“New smart machines have the hidden power to replace our minds and to move around freely in the world,” the study said. It added that the greatest job replacement is expected to come in the areas of transportation, storage, manufacturing (制造业)and retail（零售）.

The Rand Corporation recently published its own report on the future effects of automation and AI on jobs and the workplace. Osonde Osoba was a co-author of the report. He noticed that fears over machines taking jobs from humans goes back centuries. He agrees there will be major job disruptions(混乱) because of AI and automation, especially for lower skilled workers. But he believes the future problems have been overestimated(高估) without historical evidence to support the predictions. “It’s not so much that the jobs are getting replaced, but it’s more like tasks are getting replaced and jobs are reconfiguring(重新装备) over time to account for that automation.” He added that it will be very difficult for companies to completely automate most jobs, because they request a worker to perform many different duties and to respond to unexpected situations.

“If you are thinking about detailed things an individual(个人) might do to prepare themselves, I guess being more adaptable and being able to reeducate yourself to fit into a different job.” Osonde Osoba suggests.

3 . The European Space Agency(ESP) wants to build a village on the moon, said Woerner, the head of the agency, in a video interview posted on its website on March 21.

“I would like to build a base station on the moon, meaning that it’s an open station...for different states around the globe,” Woerner said to Euronews. He said the village could replace the International Space Station(ISS) in the future, which will be ended in 2024. In December Nexgen Space, a consultant(咨询) company for NASA, said that a lunar refueling station could “reduce the cost to NASA of sending humans to Mars by as much as $10 billion per year.”

According to the ESA’s plan, starting from the early 2020s, robots will be sent to the moon to begin building different facilities(设备), followed a few years later by the first humans to live there. Instead of bringing expensive resources from Earth, the moon’s natural resources like metal and frozen water could be used to build the village.

Having a lunar base could be challenging because of space radiation(辐射), meteorite(陨石) and extreme temperatures from 123℃ to 153℃, according to CNN. But Woerner said these risks could be made smaller by choosing the right locations on the moon.

“If we go into the shadow on the moon, we’ll have places where we don’t have the radiation... At the South Pole, we can find water,” he said.

Right now, the moon village is just an idea. But as the BBC said, there is a growing interest in returning to the moon and the idea will be taken seriously.

“Inside all of us there is something that goes beyond being practical,” Woerner said. “We like to discover. This is humankind and this is what brings us into the future.”
