And who gets to clean up that mess when it goes obsolete hmmmmm??:)

Head to New Zealand to watch the Mother of All Flaming Re-Entries. :P


I thought we usually dumped our trash in Oz.:ph34r:

Cool Jerry!

Our neighbor and friend, Cady Coleman, just got back from 6 months on the ISS. We've been watching her on the NASA channel and Skyped a few times. We had dinner with her last night. Got a couple stories and can't wait to hear more.

Kudos to her. I certainly couldn't hack 6 months of 'sitting in a tin can far above the world'. I think I'd be weeded out pretty early during the psychological tests! :D

Yeah good move...aim it at the Aussies properly next time...



I once bought a map of the world from Australia. It had a big yellow square in the lower right that said "World Map". It was right on top of where New Zealand should have been.

We have Tshirts which show NZ and Australia....with the names...North Island, South Island, and West Island....

What's the orbital degradation of that thing like?
When can we expect it to Skylab on us?



The ISS orbit does decay over time, and it would re-enter fairly quickly if not reboosted occasionally. The Russian segment of ISS has thrusters that can provide this reboost. There are also several different supply vehicles that bring cargo to ISS. Some of these can use their propulsion systems to boost the orbit.

The final decommissioning plan for ISS is to remotely command a deceleration burn from a supply craft engine, which would slow it enough to start re-entry. This will be targeted for a large uninhabited area of the South Pacific, such as was used for the Russian Mir space station. This is currently planned for at least 10 years from now, but who's to say. Mir was planned for a 5-year lifetime, but stayed in service for 15 years.

When I was in college I met a skydiving grad student from Oz who groused about Kiwis having just one vowel, pronounced "au".:D

It would have been cooler if they would have built it to orbit around the moon, where they have the ultimate in large uninhabited area with no one to worry about having big chunks fall on them.:ph34r:

You know, it would not be extremely difficult to put in on Lunar Orbit, it would not take all that much thrust to get it there from it's current orbit.

Of course getting to it would take something like the Gemini program.

Solid fuel propulsion would make the booster far smaller and technology advances would make in inherently safer.

We should just construct a Lunar space station and then truck it to the ISS and then relay the sub assemblies onto the Lunar surface, we could then build something to take us to Mars and beyond.

Geographically, what is wrong with Australia????...




Its above sea level....

What?

It depends on when you do it and the specifc route taken but getting to LEO takes about 8-10 km/s and going from LEO to a lunar orbit takes another 3-5 km/s; it's definitely not trivial. It's also not getting to the Moon or Mars that necessarily requires (or strongly favors) a blunt capsule design like Gemini, Apollo, Dragon, etc. but rather getting back because you have to dump all that extra velocity into the atmosphere.

Solid fuel motors can produce higher thrusts, but they aren't as efficient as liquid fuel engines and neither are as efficient as some of the more exotic thruster technologies. Fuel economy is a big deal for interplanetary travel. :)
Finally, if your ultimate goal is Mars, you'd want to stay away from the Moon on your way there unless you come up with some way to produce mass amounts of fuel from sources on the Moon. Landing on the moon sucks because you have to burn fuel to get 1-2 km/s coming and going because there's no atmosphere to help slow you down.

If it wasn't for OZ you lot would have a LOT more crime, all your crims, come here to evade being used as sheep.

It would be a LOT harder to get there. For the same cost you'd have a station that was 1/3 the size, with smaller crews, more dangerous evacuation scenarios etc.

If you wanted a station in lunar orbit you'd be a _lot_ better off building it in low Earth orbit and then using a very efficient engine to get you there in a few years. A few VASIMR engines could do it. They're already planning to add one for periodic reboosts because it's so much more efficient than chemical rockets. Add a bunch more and you could boost into lunar orbit in a few years, or go to Mars if you have a few decades. Might need to add a reactor to provide enough power.

Of course, if you have good engines, you aren't all that worried about orbital decay in the first place.

Oz has always been a penal colony.....last time I was there they asked me if I had a criminal record...I replied that I didn't think you still needed one....:D

you dont NEED one, but it does help with our relocation of you.

Bondi in the 80s, was where we put all the crim Kiwis ;):D
