who were the crew members for the mission discussed above?
Neil Armstrong, Buzz Aldrin and Michael Collins.
Apollo 11
The initial crew assignment of Commander Neil Armstrong, Command Module Pilot (CMP) Jim Lovell, and Lunar Module Pilot (LMP) Buzz Aldrin on the backup crew for Apollo9 was officially announced on November 20, 1967. Lovell and Aldrin had previously flown together as the crew of Gemini 12. Due to design and manufacturing delays in the LM, Apollo8 and Apollo9 swapped prime and backup crews, and Armstrong's crew became the backup for Apollo8. Based on the normal crew rotation scheme, Armstrong was then expected to command Apollo 11.

There would be one change. Michael Collins, the CMP on the Apollo8 crew, began experiencing trouble with his legs. 
where was the first moon landing launched from Kennedy Space Center what was the name of the mission? Apollo 11 which operations were performed on the surface of the moon? They jettisoned "Eagle" before they performed the maneuvers that propelled "Columbia" out of the last of its 30 lunar orbits onto a trajectory back to Earth. what is the surface geology of the said astronomical body like? Its atmosphere and oceans were formed by volcanic activity and outgassing. how strong is its magnetic field compared to earth? It has an external magnetic field of generally less than 0.2 nanoteslas, or less than one hundred thousandth that of Earth. and gravitational field? UNANSWERABLE does it have any impact craters? Yes, which formed when asteroids and comets collided with the lunar surface. on which other planets are such craters found? Mercury, Callisto, Ganymede are there such craters on earth? Yes where are they located? UNANSWERABLE how are they identified? Non-explosive volcanic craters can usually be distinguished by their irregular shape and the association of volcanic flows and other volcanic materials.

Apollo 11 [SEP] Prime crew
Doctors diagnosed the problem as a bony growth between his fifth and sixth vertebrae, requiring surgery. Lovell took his place on the Apollo8 crew, and when Collins recovered he joined Armstrong's crew as CMP. In the meantime, Fred Haise filled in as backup LMP, and Aldrin as backup CMP for Apollo 8. Apollo 11 was the second American mission where all the crew members had prior spaceflight experience, the first being Apollo 10. The next was STS-26 in 1988. Deke Slayton gave Armstrong the option to replace Aldrin with Lovell, since some thought Aldrin was difficult to work with. Armstrong had no issues working with Aldrin but thought it over for a day before declining.
