SPACE TUG [“PIONEERING THE SPACE FRONTIER”]
Notes:
Another space tug from the 1986 Pioneering the Space Frontier policy report. These vehicles would transport crews and equipment from space stations in low Earth orbit to lunar orbit. Boeing and Martin Marietta were awarded $1-million study contracts in July 1984 as NASA was hoping to receive full funding to complete the $2.75-billion project in the 1990s. However, the project was essentially postponed indefinitely in late 1985 when the Boeing & Martin contracts expired.
