1、 An experimental clean-up device called RemoveDEBRIS has successfully cast a net around a dummy(仿真的) satellite, simulating a technique that could one clay collect spaceborne garbage. The test, which was carried out this week, is widely believed to be the first successful demonstration of space clean-up technology, experts told CNN. And it symbolizes an early step toward solving what has already been a critical issue: junk in space. Millions of pieces of space junk are turning around in orbit, the result of 50 years of space travel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite can cause critical(严重的) damage. Various companies have plans to send thousands of new satellites into low-Earth orbit, already the most crowded area. The RemoveDEBRIS experiment is run by a company and researchers led by the U. K.’s Surrey Space Centre and includes Airbus, Airbus-owned Surrey Satellite Technology Ltd. and Fiance’s ArianeGroup. Guglielmo Aglietti, director of the Surrey Space Centre, said that an operational version of the RemoveDEBRIS technology would cast a net that remains fastened to the main satellite so the debris(碎片) can be dragged out of orbits. It could target large pieces of junk, including dead satellites up to 10 meters long. The RemoveDEBRIS satellite will conduct a few more experiments in the coining months, including testing navigation features that could help guide the satellite to a specific piece of debris. There are still enormous barriers to clear before operational clean-up tasks are underway, he said, and the most discouraging is figuring out how to fund such projects. Aglietti, the Surrey professor who helped lead the RemoveDEBRIS project, said, "The challenge will lie in persuading the relevant authorities to sponsor these tasks." Aglietti said he hopes RemoveDEBRIS will conduct a few clean-up tasks per year, targeting the largest pieces of junk in the most crowded orbits. 1.What is the use of the RemoveDEBRIS satellite?

But that may only be true if the technology challenges us. In a world run by intelligent machines, our lives could get a lot simpler. Would that make us less intelligent? After the Industrial Revolution, machines began to replace manual workers. The process played out in agriculture as well as manufacturing so that groups of agricultural workers were replaced and forced to move to cities to make a living. When machines took away much of the manual work, people became less physically active and gained weight. The sedentary (久坐的) lifestyle contributed to a worldwide spreading of overweight and related metabolic disorders such as heart disease, secondary diabetes and kidney disease . As our bodies rested, our brains were forced to work harder, however. It is much more difficult to drive through an overcrowded modern city than it is to move around in a small rural village, for instance. Modern jobs are also more complex and urgent and they require more education because employees need to process new information quickly. Even during our leisure time, our brains work harder due to greater availability of books and explosion of audiovisual media, for entertainment, study, music, news, and so forth. Now in the Internet age, the amount of information grows fast along with the advance of electronic technologies. The number of people with whom we interact electronically grows by leaps and bounds thanks to the ease of use of social media like Facebook and Twitter.
