AI Thread Summary
Astronauts on the International Space Station (ISS) conduct various research activities, including testing space toilets to ensure functionality for future missions to Mars. Recent discussions highlight the focus on studying the effects of prolonged spaceflight on the human body, although some missions may be shorter than previous Russian missions. The ISS is equipped with advanced technology that supports these studies, which may contribute to the perception that current missions are more significant. There is skepticism about the validity and depth of some research missions, questioning whether they are substantial or merely for public relations. Overall, the ISS plays a crucial role in advancing space research and technology development.

Top of the day to ya,
I monitor the development of the International Space Station and I have some idea of what the daily routine of the crew looks like but I am missing a cruical piece of information which seems to be never mentioned. What exactly are the astronauts doing up there? What do they research? Wikipedia nor Google satisfied me. :(

Cheers

I knew we should have sent a certified plumber up there with these guys.

I don't understand this either. A big deal was made in the Canadian media recently about the latest Canadian astronaut to go up to ISS (on the Soyuz, not the shuttle). His mission was ostensibly to study the effects of prolonged spaceflight on the human body. But if I recall correctly, the duration of this mission is actually shorter than the durations that some of the Russian cosmonauts etc. have been in space in the past. Is it just that the ISS has better equipment for doing these studies? Or are these missions just made up in order to sound good?
 
The ISS has led to the development of a range of advanced technologies detailed by Nasa here http://www.sti.nasa.gov/tto/ISSspin.html

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
