Apollo 11
NASA's last space shuttle mission, STS-135, launched on July 8, 2011, and concluded on July 21, 2011. This mission was conducted by the shuttle Atlantis and marked the final flight of the Space Shuttle program.
NASA's Houston space headquarters is called the Johnson Space Center (JSC). It is responsible for human spaceflight training, research, and mission control. The center plays a critical role in the agency's astronaut programs and various space missions, including those related to the International Space Station.
The International Space Station communicates with Earth primarily through antennas and satellites. Data is transmitted using radio waves to ground stations located around the world. These ground stations then relay the information to mission control centers for analysis and communication with the astronauts.
Radio, possibly lasers. Not sure about that last but would not put it past the military and alphabet soup agencies. Seems to me that a laser could be aimed exactly at a satellite and so there would be no need to broadcast radio which other nations might be able to pick up.
Deep Space Network expanded 64-m antennas to 70-m antennas. This info is strait from the nasa website

Apollo 11
The Deep Space Network (DSN) is a network of antennas and communication facilities used by space missions to communicate with spacecraft in deep space. It allows for continuous communication with spacecraft, enabling the transmission of data, commands, and navigation signals.
there where nine atsronuts :)
There were 2 astronauts on each Project Gemini mission.
There were two men in each Gemini module(The constellation Gemini is the twins)
Due to limitation in budget, the NASA is going to quit manufacturing Space Shuttles and again start making ordinary rockets.
James J Herbert has written: 'Technology needs of advanced earth observation spacecraft' -- subject(s): Radio antennas, Microwave antennas, Space probes, Space vehicles
They use the Deep Space Network which is a collection of microwave dish-type antennas placed at various points round the Earth in California, Spain and Australia. Radio signals from any spacecraft more than 30,000 km from the Earth can always be received by at least one of the stations. The antennas have diameters of up to 70 metres (230 ft).
Two. A command pilot (commander) and a pilot (technically a co-pilot -- a term which is taboo among astronauts).
