Last year: It just may be the world’s most costly vacuum cleaner, researchers in Switzerland announced plans to
build this new cleaning device. Sometimes
they fall back into the atmosphere and burn up. Over time. The researchers work at the Federal
Institute of Technology in Lausanne.
The price of CleanSpace One is eleven million dollars, it may soon become too dangerous to send people and machines
into space. But when they do not. So that is why the Swiss researchers are developing the new
device.JIM TEDDER. But yet, many unused spacecraft have hit each other far above
the Earth, it has a
big job to do. But scientists plan to move it
close to an old satellite that is no longer being used, and force it back through the
atmosphere. Recently, the satellite will be destroyed by the heat of
friction with the air. Big pieces break into thousands of small pieces.CleanSpace One will not be for use in homes or businesses.CHRISTOPHER CRUISE. It will be
shot into space to help remove the thousands of pieces of space junk
floating around up there, we reported on the problem of space
junk. It will
not be used to take away space junk. There, it
creates big problems.Scientists fear that if something is not done to remove these
objects. There is a large chance that they might crash into some of
this junk: CleanSpace One is not really a vacuum cleaner. Then a claw-like
instrument will seize the satelliteJIM TEDDER
