NOTE: This chronology contains manned space missions; unmanned test flights of manned spacecraft; significant launch vehicle tests; unmanned lunar probes; select space biology flights; piloted stratospheric balloon flights; flights above 50 miles (264,000 feet) by the X-15 rocket plane; and other significant events in the development of manned space programs.
Biological satellites are listed only when they directly supported a manned space project. In the case of missions where crewmembers were launched in one spacecraft and returned in another, the crew names are with the launch spacecraft and explanations of their return to Earth are in the flight description.
A three- or four-letter country designation is given at the end of each entry. The country designations used are as follows:
BEL Belgium
