An Astronaut's View of Space Station Tech
An anonymous reader writes "Here's a chat with a NASA astronaut about how they fix system outages on board the International Space Station, what kind of computing tech they use on board, and how he would like to see the iPad used on the ISS." He talks about using 5 year old laptops because they had been tested to handle the stresses of space travel, as well as the importance of being able to read emails and send pictures to family while aboard a space station for months at a time.
One page version of the article.
Not that I bothered reading it.... if they are quoting astronauts advocating ipads, it is clearly just yet another propaganda piece pushing mindless consumption. Very few people will operate a computer in zero gravity, and whilst it is possible that no keyboard and being stuck in a closed playground could be good in space, I should think the ipad would suck as much as when on the ground.
No, this is not true. We had a story here some time ago about how they've upgraded to the Lenovo T61p Thinkpad. 1680x1050, yeah! I know this because I have a T61. They're damn solid, and pretty contemporary—Core 2 Duos around 2.5 GHz.
Bio questions? Ask me to start a Q&A journal. Computer analogies available for most topics!
A few interesting things about GPS in space:
a) All GPS receivers capable of sensing a position higher than 11 miles or a velocity higher than 515 meters/sec are classified as munitions and require state department licenses to export... Pretty much no consumer GPS receiver, including the iPad is going to be able to find itself in orbit. OTOH, the Space Shuttle itself uses GPS for space navigation, and I'm sure the ISS has a GPS receiver on board as well that can find its own location.
b) The GPS satellites orbit at 20,000 km, while the ISS orbits at 350km... The strength of the signal isn't really all that affected.
Make me a friend and I'll mod you up
I'm typing this on a 5-year-old laptop with a 5-year-old installation of XP on it. I've had to add RAM and replace the battery and swap out the charger a few times, but otherwise this thing still runs great. You just have to actually take care of your equipment.
