At the end of the mission, the Altair spacecraft would have launched into lunar orbit to link up with the Orion spacecraft in lunar orbit rendezvous.

Constellation will also employ an Earth orbit rendezvous mission profile, which was dropped in favor of lunar orbit rendezvous in Apollo.

It met the initial requirements for a Lunar orbit rendezvous and lunar landing mission.

Both would enter LLO for lunar orbit rendezvous prior to landing at equatorial or polar sites on the moon.

But the change to lunar orbit rendezvous, plus several technical obstacles encountered in some subsystems (such as environmental control), soon made it clear that substantial redesign would be required.

Despite some controversy, a lunar orbit rendezvous for the lunar module was chosen over an Earth orbital rendezvous.

As an adult he worked on the Apollo program, determining fuel requirements and radar accuracy requirements for lunar orbit rendezvous.

And yet you plotted an orbit rendezvous?

Thomas Dolan was an American engineer who proposed the first fully developed concept of Lunar orbit rendezvous for the Apollo program while working at Vought Astronautics.
