NASA rules.... |
I want to go up in that new space capsule they are making. It is going
to have totally new avionics, glass cockpits, multi function, it is
going to be a space craft designed with modern aircraft style
controls, as opposed to all the switches and so on or the Shuttle's
1980s tech... Multitasking, high speed computing, six person capacity,
and it can fly to the Moooooooooooon........

100% incidence of radiation cataracts in Skylab, MIR and ISS FUBAR.
That is still deep inside the magnetosphere, boyo, that redirects hard
stuff to the poles. Being above the atmosphere means losing 908
g/cm^2 of radiation shielding. Yer gonna get cooked.
Al,
Are you aware of any peer-reviewed cites to support these statements?
John
From "Space Physiology", Jay C. Buckley:
Cataract threshold occurs at about 2 Sieverts (Sv), with increased risk
in astronauts exposed to > 8 mSv. The 10-year career limit is between
0.4 and 3 Sv, depending on sex and age. an 8-day shuttle flight
provides a dose of 5.3 mSv, a 5-month stay on Mir provides 0.16 Sv, a
trip to the Moon 110 mSv, a trip to Mars is 0.5 Sv /year travel and 0.12
Sv/year on the surface.
