The topics in this 20 minute plus segment focused on recent news reports regarding the risk to the ISS by incoming space junk. The six crew members got into their Soyuz lifeboats, sealed the hatch and in the worst case scenario of a hit and damage to the ISS, they were ready for an emergency return to Earth. You can read about this incident from many sources on the web or you can check out the story here: www.guardian.co.uk/science/2009/mar/13/space-junk-nasa. Mr. Batchelor started out by asking Dr. McKnight if NASA had Plan B ready given the high number of debris objects in space. Dr. McKnight talked about the debris that is cataloged and not cataloged, and the risk factor the ISS astronauts accept by going to the space station. Darren then spent a few minutes talking with us on how solar cycles impact the quantity of space debris in the lower orbits. We also talked about liability issues should debris do damage. In the latter part of our discussion, John asked Darren about remedies. We talked about them for both the LEO orbits and the higher GEO orbits. Tumbling Russian rocket bodies were mentioned and I asked how the tumbling is stopped so the rocket body can be mitigated as a piece of debris. Our discussion ended when John asked Darren if there were space debris cops to enforce debris mitigation efforts on launching companies and countries.
