Unit 10, exercise 24a Russian and US satellites crash in space NASA scientists are closely monitoring the skies after satellites crashed into each other over Siberia in what experts have said is the first collision of its kind. The accident, which took place more than 400 miles above the Earth’s surface on Tuesday, has left a large cloud of debris floating in space. NASA officials are keeping watch to see if the debris could endanger other spacecraft, although they said it was unlikely that the International Space Station could be damaged. “It will be weeks at least before the true size of these two clouds is known,” a NASA spokesperson said in a warning message. Air Force Lieutenant Colonel Les Kodlick, said, “We believe it’s the first time that two satellites have crashed in space.” Both satellites were used for telecommunications. The crash has added some 500 to 600 new bits of debris (now being monitored by the command’s Joint Space Operations Center) to the 18,000 or so other man-made objects already in space.
