Page 2 - HC A03/MF A01; also available from GAO. Gaithersburg, MD HC first five copies free, additional copies $2.00 Experts estimate that more than 3.5 million man-made objects are orbiting the earth. These objects - space debris - include whole and fragmentary parts of rocket bodies and other discarded equipment from space missions. About 24,500 of these objects are 1 centimeter across or larger. A 1 -centimeter man-made object travels in orbit at roughly 22,000 miles per hour.

Page 8 - The natural objects are meteoroids (meteor particles), while the orbiting man-made objects — space debris — include whole and fragmentary parts of rocket bodies and other discarded equipment from space missions.
Page 9 - A 1 -centimeter man-made object travels in orbit at roughly 22,000 miles per hour. lf it hit a spacecraft, it would do about the same damage as would a 400-pound safe traveling at 60 miles per hour. The Government Accounting Office (GAO) reviews NASA's plans for protecting the space station from debris, the extent and precision of current NASA and Defense Department (DOD) debris-tracking capabilities, and the extent to which debris has already affected shuttle operations. GAO recommends that the...
