Space Tug

Space Tug is one of those many sci-fi novels from the 1950s which tried to give a practical, realistic rendering of the problems of concerns of rocket flight into space - dealing with the physical strains of the G-force during lift-off, overcoming the disorientating effects of weightlessness (the astronauts wear magnetic-soked shoes like in 2001: A Space Odyssey), growing vegetables in a hydroponic farm on a space station, etc.
