1973
two test flights of the 7k-t were conducted prior to committing the redesigned soyuz to a manned mission. kosmos 496 was launched on june 26, 1972 and spent a week in space, part of it in powered-down mode. then on september 2, an attempted launch of a zenit reconnaissance satellite failed to orbit due to a malfunction of the vernier engines on the blok a stage. the existing stock of soyuz boosters had to be modified to prevent a recurrence of this failure mode on a manned mission, which delayed the next test until almost a year later when kosmos 573 launched on june 15, 1973 and spent two days in space. with this done, the way was cleared for the first manned test, soyuz 12, in september.

the launch spurred a series of federal government initiatives ranging from defense to education. renewed emphasis was placed on the explorers program (which had earlier been supplanted by project vanguard) to launch an american satellite into orbit; this was accomplished on january 31, 1958 with the successful launch of explorer 1. in february 1958, eisenhower authorized formation of the advanced research projects agency, later renamed the defense advanced research projects agency (darpa), within the department of defense to develop emerging technologies for the u.s. military. on july 29, 1958, he signed the national aeronautics and space act, which established nasa as a civilian space agency. nasa took over the space technology research started by darpa, as well as the air force's manned satellite program, man in space soonest, which was renamed as project mercury. the project's first seven astronauts were announced on april 9, 1959.
