【正文】 ong. The RemoveDEBRIS satellite will conduct a few more experiments in the ing months, including testing navigation features that could help guide the satellite to a specific piece of debris.Jonathan McDowell, an astrophysicist at the HarvardSmithsonian Center for Astrophysics, said the success of this week39。s experiment was exciting, but he cautioned against over publicizing it. There are still enormous barriers to clear before operational cleanup 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 cleanup tasks per year, targeting the largest pieces of junk in the most crowded orbits.（1）What is the use of the RemoveDEBRIS satellite?

It could be hard to find hope there. It took decades for public perception of the river to shift. But activist citizens, who collaborated with industry, government, and environment groups never gave up on their polluted river—the Buffalo River gradually went from being considered a lost cause to a place worth fighting for. And by now the cleaned—up water is one of Buffalo39。S biggest attractions. By the 1960s, the river was seen as one of the worst sources of pollution pouring into the Great Lakes. The Buffalo River had caught fire many times. The surface had an oily layer, and any fish caught there were not eatable. The waterway39。s fate started shifting in the mid1960s. Stanley Spisiak was a local Polish—American jeweler by day, but by evening he was the kind of guy who39。d chase down dumpers(垃圾車)he spotted on the Buffalo River. By 1966 he found himself winning the National Wildlife Federation39。s Water Conservationist of the Year award. And before long he got a nickname: Mr. Buffalo River. But there was only so much he could do—the river was still declared biologically dead in 1969. Jill Spisiak Jedlicka is his greatgrandniece. She picks up where he left off by directing the river39。s protector organization, Buffalo Niagara Waterkeeper. Professor Schneekloth and seven friends founded the organization as an allvolunteer nonprofit in 1989, after organizing the first river cleanup that year. Today the group employs 27 fulltime workers and has helped oversee the Buffalo River39。s $100 million restoration. So far, the Buffalo River39。s water quality has restored, but it is still an ongoing issue, as sewage(污水)can overflow into the river after storms. Habitat restoration continues as well。 fish and plantings are still being sampled to measure how well it39。s gone. （1）What did the Buffalo River use to be?
