Launched in September 2011, Tiangong 1 (Chinese for "heavenly palace") was China's first prototype space station, serving as both a manned laboratory and an experimental testbed to demonstrate orbital rendezvous
Musk added he would "try to double the number of flights with each Earth-Mars orbital rendezvous
, which is every 26 months, until the city can grow by itself.
Both of these solutions involve similar orbital rendezvous
and docking procedures, however that is where the similarity ends.
He is famous for his work as an aerospace engineer, who designed an orbital rendezvous
technique critical to future planetary landings.
In the 1980s, Aldrin adapted his expertise in orbital rendezvous
to conceptualize the "Aldrin Mars Cycler," a spacecraft transportation system perpetually cycling between Earth and Mars that would make it possible to ferry astronauts back and forth to the Red Planet.
automated intelligence and computer systems will be an integral part of the missions.
