Five decades have now passed since the final curtain was drawn down on Project Gemini—America’s effort to perfect the techniques of rendezvous, docking, long-duration spaceflight, and spacewalking—ahead of fulfilling President John F. Kennedy’s goal of landing a […]

'Send Up a Tanker': 50 Years Since the High-Flight of Gemini XI (Part 2)

Half a century ago, this coming week, on 12 September 1966, Gemini XI astronauts Charles “Pete” Conrad and Dick Gordon launched from Earth within a two-second-long “window” and […]

'Would You Believe M=1?' 50 Years Since the High-Flight of Gemini XI (Part 1)

Fifty years ago, this month, Pete Conrad and Dick Gordon’s Gemini XI mission would carry them to a peak 850 miles (1,370 km), which remains the highest altitude of any Earth-orbital mission. Only the Apollo lunar flights traveled higher on their expeditions to the Moon. Photo Credit: NASA

Not all astronauts get on with […]

'Otherwise Engaged': 50 Years Since the Double-Rendezvous, Double-Spacewalk Mission of Gemini X (Part 1)

Six hours after launching from Cape Kennedy on 18 July 1966, Gemini X Command Pilot John Young and Pilot Mike Collins rendezvoused and docked with Gemini-Agena Target Vehicle (GATV)-5005. It was the first of a record-setting two rendezvous to be performed during their three-day mission. Photo Credit: NASA, via Joachim Becker/SpaceFacts.de

Five decades ago, one of the hairiest and most difficult missions in America’s space history unfolded. Gemini IX-A was already complex—a three-day flight, involving rendezvous, docking, maneuvering, and spacewalking—but had endured additional […]

'Like an Angry Alligator': 50 Years Since the Challenging Mission of Gemini IX (Part 1)

In many ways, NASA’s Gemini IX mission—tasked with spending three days in space, performing a lengthy spacewalk, a rendezvous, and a docking with an unmanned Agena target vehicle—was hamstrung by bad luck. First, in February 1966, its […]

'More Routine, Less Newsworthy': 50 Years Since Gemini IX Lost Its Agena (Part 1)

Had history been kinder, this might have been the view from Gemini IX’s windows, 50 years ago, this week. However, the failure of the Gemini-Agena Target Vehicle (GATV) to reach orbit on 17 May 1966 led to a two-week delay to the mission of Tom Stafford and Gene Cernan.

'Tumbling End Over End': 50 Years Since the Traumatic Mission of Gemini VIII (Part 2)

Fifty years ago, this week, NASA astronauts Neil Armstrong […]

At the dawn of 1966, America’s drive to land a man on the Moon had accelerated into high gear. Five Gemini crews had shown that astronauts could survive in space for long enough to complete the […]
