I have all the worry, He has all the fun
Oh yes, I also got to meet her husband, Dr Franklin Chiang Diaz (veteran of 7 Shuttle missions) too. (BTW he looks about 30, and wears braces.. Not many people know that)
Dr Chiang Diaz is currently visiting the Australian National University, pursuing what seems to be a favourite topic of his : Plasma Rocketry. He described the specific impulse of such engines as being in "the thousands", compared with the 200-300 of current rockets.
Also there at the presentation was Dr Ben Greene, CEO of "the most interesting company in Queanbeyan", Electro Optic Systems, otherwise known around here as "Lasers R Us". Apart from doing a lot of highly classified Defence work, they've got a laser tracker that can get the position of any piece of space junk to an accuracy of a millimetre. Their more powerful lasers can also be used to zap a few microns of surface off of a spent satellite (or whatever) in LEO and push it into a decaying orbit. He reckons the problem of "space junk" will be licked, starting in about a decade.

Commenters are expected to be polite to each other, but the same standard doesn't apply to comments regarding me.
Australian commenters are very very strongly advised to publish anonymously. Sydney alone has more defamation actions than the entire USA and UK. Nearly double that of the UK in fact.
As Google does not reliably inform me that a comment has been posted, and I have no control over first publication, I assert that all comments are innocently disseminated under the NSW DEFAMATION ACT 2005 - SECT 32 and similar acts.
