What is Earth orbit rendezvous?
Earth orbit rendezvous is a method for conducting round trip human flights to the Moon. It involves using space rendezvous to assemble and possibly fuel components of a translunar vehicle in low Earth orbit.
Questions about Earth orbit rendezvous
Short answers, pulled from the story.
Why did NASA reject Earth orbit rendezvous for the Apollo program?
NASA ultimately rejected it in favor of lunar orbit rendezvous because a single spacecraft capable of making the return trip from Earth orbit would be too large. The decision stemmed from the enormous size requirements needed for direct ascent vehicles that also had to handle a soft landing on the lunar surface.
When did Gemini 8 achieve its first successful docking with the Agena target vehicle?
Gemini 8 achieved its first successful docking with the Agena on the 16th of March 1966. This mission followed earlier rendezvous attempts by Gemini 6 and Gemini 7 during 1965 without using Agena.
Which country adopted Earth orbit rendezvous as their preferred methodology for human lunar missions?
The Soviet Union adopted it as their preferred methodology while American agencies moved away from the concept. Their strategy focused on achieving human lunar missions through in-space assembly or refueling using smaller rockets launched individually.
What happened to Project Constellation plans involving Earth orbit rendezvous?
Project Constellation intended to use an Earth Departure Stage alongside the Altair lunar lander but faced cancellation in October 2010 before full implementation could occur. The program aimed to apply decades-old principles to modern spacecraft design by launching Orion capsules separately to meet components in orbit.
