NASA launched two spacecraft 1 hour and 37 minutes apart in 1966 with the Gemini 11 crew and its Agena target vehicle.
The Gemini 11 mission conducted tethered spin tests in low Earth orbit to learn about artificial gravity.
Gemini 11 in 1966 reached an apogee of about 1,375 km.
Space Adventures set a goal for the Crew Dragon mission to reach an altitude of more than 1,0 m, approaching the crewed orbital apogee record of 1,374 km set by Gemini 11 in 1966.
