Traveling To Venus
(i) Nuclear rockets transport people between planets, reaching Venus in a hundred and twenty days depending on orbits.
(ii) Solar sails carrying freight take three or four times as long but are robotically controlled because no one can survive that long without gravity and also because there is greater danger of solar flares on longer journeys.
(iii) Passenger ships gradually adjust to denser air and higher oxygen en route to Venus.
(iv) Anyone even short listed to go to Venus has two or three degree-equivalents and is physically of almost Olympic caliber.
(v) Nevertheless, they need weeks or months of "...carefully phased acclimatizing..." (p. 11) after arriving.
This sounds plausible and torpedoes any idea that I might have had in the 1950's of joining Dan Dare's Interplanetary Space Fleet if I lived into the 1990's.
