Men Into Space

Senator Jim Sloane questions the need for and cost of a mission to the moon after McCauley's first effort to the moon fails and his second effort leaves a crewman seriously injured during takeoff.

McCauley races against time in order to save an astronaut who is trapped when assembling the prefabricated units of a space station. The astronaut is the son of a air force general and trapped when his sleeve catches between sections of the space station.

When an astronaut is stricken by a heart attack on the Moon, McCauley must find a way to get him back to Earth.

When an experimental nuclear-powered missile goes out of control, its creator insists on accompanying McCauley into space to try and disarm it before it can strike the moon and wipe out a twelve-man expedition.

Trailblazer I is on route to the Moon when one of the crew gets word his wife has been hurt in a car wreck. Although distracted, the crewman needs to focus all his skills and abilities to overcome a major accident.

Returning from the Moon with valuable spore samples the crew of MR7 are rendered unconscious. Earth sends a rescue mission but a decision has to be made that could put everyone's life at risk.

An asteroid straying close to Earth becomes the subject of an experiment. It is decided to scout the asteroid with a view of turning it into a mobile space station. If not the rock must be destroyed.

Shortly after leaving the Moon a spacecraft is hit by an asteroid destroying their oxygen supply. The three man crew now become engaged in a life and death battle to extend their oxygen supply long enough to make it home.

Test continue on a new alloy for re-entry. On one test the ship acts erratically and although the crew is saved the ship is lost. A second mission is launched to try and understand what went wrong.
