17 Apr 07 - 02:27 PM (#2027997) Subject: BS: Space Debris From: beardedbruce Date: Thurs., April 19, 2007 Time: 1:30 p.m. ET (30-minute presentation, 15-minute Q&A) "On January 11, China conducted an anti-satellite (ASAT) missile test against one of its old polar-orbiting weather satellites. The ASAT test produced a ring of debris of at least 1,337 pieces large enough to be tracked by the U.S. Space Surveillance Network, making it the largest debris-generating event in history. During this free online event, Dr. T.S. Kelso, senior research astrodynamicist with the Center for Space Standards & Innovation (CSSI), AGI's research and educational arm, will discuss the implications of the test on other satellites in Earth orbit, showing: The evolution and distribution of the debris using AGI Viewer software; The portions of Earth orbit affected by this event, including the increase in orbital conjunctions as reported in SOCRATES; and Predictions of the orbital lifetimes of debris, much of which will remain in orbit for at least a century. This webinar is an encore presentation of Kelso's recent briefing on the topic at the National Space Symposium in Colorado Springs. Visit www.agi.com/webinars today to register. While there, download recordings of past online events. As a thank you for joining us for the live event, you'll receive a gift once you submit your event feedback survey! Any questions?

Tiny bits of debris orbiting 15 to 20 times faster than a slug thrown by a high powered rifle could fatally injure spacecraft and personnel. There needs to be a worldwide ban on weapons and weapon testing in space. Also multiple use vehicles and recoverable boosters greatly cut down on space debris. |

The concern here is not so much that China did this, but that they didn't move the satellite to some lower orbit first, where the bits would get more air resistance and drop out quicker. Graham. |
