11,000,000 miles-nearly fifty times the dis tance from here to the moon. What lies ahead now on the road to the moon? Dr. Mueller forecasts a wind-up of the Gemini program this year, with five two-man flights of from one to three days' length. "On each flight," he says, "the astronauts will practice rendezvous and actual link-up with an Agena or a similar target. Then they may use the fuel supply of the Agena to propel 552 both vehicles into new orbits and maneuvers. On each flight an astronaut may leave the Gemini vehicle to 'walk around the earth.' * And once the Gemini and Agena have docked as a unit, they may seek out and rendezvous with a second Agena to be left in orbit from a previous Gemini flight." As Gemini comes to an end, the real moon *"America's 6,000-Mile Walk in Space," in the Sep tember, 1965, GEOGRAPHIC, described this feat.
