In the January 1950 issue of Redbook magazine, author Philip Wylie made predictions mostly focused on leisure culture in the future. On space traveling, he writes 'Travelers will make the round trip to Mars via space ships, carrying small hydroponic gardens to insure a steady supply of oxygen and to deodorize the air. Several parties of sportsmen-scientists will have been lost on expeditions to Venus.' In hindsight, it seems fair to conclude that these predictions were a tad too ambitious for the year 2000.
