If you make the oxidizer 'less dangerous' it wouldn't be very effective... :P When hydrogen peroxide decomposes, it breaks down into water vapour and monatomic oxygen at high temperatures. The vapours themselves aren't all that dangerous... but their associated high temperature IS. Which is...

Regarding screwdrivers - magnetic bits can be quite helpful, because holding those screws in place within the tight confines of some motherboards can become awkward... if not potentially damaging to connectors.

Jerry Pournelle wrote about something similar in the mid-70s. He suggested using large rocket engines firing through MHD-generator tubes to alleviate the power-consumption problem. Atmospheric losses would be minimized by using a frequency that is not easily absorbed by the air (he suggested...

Well... for one thing, the lunar L2 point is unstable. You'd have to constantly 'tweak' the orbit in order to remain stationary. A surface-based installation wouldn't have that problem.

Thanks... :tiphat:

Forgive me for being dense... but I don't understand your question. Are you wanting to put a picture of a rocket on an online map somewhere, or something else...?

Yes. (In Canada, in case that matters...) It should be a required course, but only as an 'awareness' exercise - not necessarily as a pass-or-fail, diploma-is-dependent-on-passing requirement. (Although it may be optional to make it so, if attendance is poor...) Since young people are...

Turns out that one of the latest upgrades of NIS *does* let my file/printer sharing work. (Go figure... :rofl:) As to Windoze... I'm still using XP Pro on my machines. (Well... the notebook I bought to use at launchsites came with Vista Business, but the machines I put together myself are...

I transfer files on USB flash-memory sticks myself. :P But it's rather hard to share printers that way... Maybe I'll go back to ZoneAlarm for my firewall, and just keep Norton for my virus-scanner...

I've grown used to Norton myself - I use Internet Security 2009 on two of my home computers. Still... I'm beginning to think that it's Norton that's messing up my ability to share files and printers over my network...since it started happening before I changed my router. :(

I was actually thinking more along the lines of moving a base from one point on Earth to another. (Say... duplicating KSC in Nova Scotia... :P )

I have two watches right now... both Timex. One is a digital-compass watch I've had for three years now - the plastic band is broken, and I haven't found a local place that will repair/replace it. The other is a heart-monitor watch that was given to me by my fitness instructor last month.

Personally, I'd like to see them do an unmanned abort-and-destruct test... not only to see if the abort system works, but to see if it will actually carry the capsule out of the cloud of flaming debris from the solid-rocket destruction. (After all... if the parachutes get hit by debris and...

Interesting concept... since it was a Democrat that charged NASA with a mandate to expand the frontiers of space (Kennedy)... and it was a Republican who first started cutting back the Apollo program (Nixon).

I'm about a hundred pages into Steven Baxters' novel "Evolution". Wonderfully speculative stuff. :speakcool:
