I'm trying to calculate the protection provided by the earth's magnetic field from HZE particles to astronauts in LEO, eg: the ISS.

comment Why can there be fire in space while there is no oxygen?
Not all rockets require oxidizer. Nuclear thermal rockets use the energy from a nuclear reactor in place of chemical energy to heat the fuel and generate thrust. Solar thermal rockets have also been proposed.

comment Optimal Angular Field of View (AFOV)
So from this answer I can infer two advantages from a larger FOV. 1) seeing entire DSOs at higher magnifications 2) for non-motorized scopes less frequent adjustments due to the object you're observing moving out of the FOV.

comment After the Space Shuttle is retired, how will the new sections of ISS be launched?
This answer is incorrect. One module remains to be launched: Nauka is scheduled to launch on a Proton rocket in May 2012. See nasa.gov/mission_pages/station/structure/iss_manifest.html
