Aug. 18, 1961 - NASA has decided to omit further suborbital flights. Instead, it will concentrate on an orbit of the earth with a manned vehicle, hopefully by November. The agency said that the two suborbital flights made by American astronauts this year were sufficient in providing necessary data. After a manned vehicle has been orbited, the agency will proceed from Project Mercury, the current program, to Project Apollo. In that program, more than one man, possibly three, will be sent into orbit. That flight, however, is three or four years away. Beyond that is a scheduled flight around the moon and, by 1970 it is hoped, a landing on the moon.
