Panel Advises Longer Life For Space Station

suraj.sun writes "A presidential panel reviewing the US space program has found that the United States needs to boost NASA's budget by $1.5 billion to fly the last seven shuttle missions and should extend International Space Station operations through 2020. The panel also proposed adding an extra, eighth shuttle flight to help keep the station supplied and narrow an expected 5-7 year gap between the time the shuttle fleet is retired and a new US spaceship is ready to fly."

Re:WTF isnt a space station permanent?

[plasmacutter]

Every space station is temporary. Eventually things start to fail (see MIR) and end up becoming very expensive to maintain or unsafe to keep sending missions.

This is not how commercially viable megastructures work though! and that's my point!

Modern commercial structures are bipartite, consisting of a permanent shell and a modular interior. Think of any modern office building or strip mall. When one company moves out its a matter of simple retrofitting to get the next tenant company at home and functioning.

This is how a space station SHOULD work. It should have a permanent shell capable of containing life support, modular, easily replaced apparatus for essentials (air and water supply/purification), and an interior which is easily fitted and re-fitted as necessary.

Doubleplusgood points for artificial gravity through rotation to prevent bone loss of employees for future commercial tenants.

Ion engine?

[Tablizer]

Couldn't they attach an ion engine and let the solar panel's power keep it in orbit if by chance it becomes unmanned for a while?

Why deorbit it at all? They could attach an ion drive to the station and slowly raise the orbit until it won't decay for another 500 years or so. The station can withstand that much acceleration. There's certainly space enough up there, it's not like it takes up valuable room... also, lifting all that mass into orbit has been so stupidly expensive, they should at least reserve the option to use it at some point in the future. Anything else is irresponsible.

At the very least, it would be an interesting machinery longevity experiment. Re-visit the station in 50 years or so, just to see how it has stood up to the environment up there. Also, at some point in the future it will be an archaeological artifact, and valuable to future historians.
