The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup 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 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 damage. Various panies have plans to send thousands of new satellites into lowEarth orbit, already the most crowded area. The RemoveDEBRIS experiment is run by a pany and researchers led by the U. K.39。s Surrey Space Center and includes Airbus, Airbusowned Surrey Satellite Technology Ltd. and France39。s ArianeGroup. Guglielmo Aglietti, the director of Surrey Space Center, said that an operational version of the RemoveDEBRlS technology would cast a net that remains fastened to the main satellite so the debris can be dragged out of orbit. 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 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?
