On September 17, 1976, NASA publicly unveiled its first space
shuttle, the Enterprise, during a ceremony in Palmdale, California.

Development of the aircraft-like spacecraft cost almost $10 billion
and took nearly a decade. In 1977, the Enterprise became the first
space shuttle to fly freely when it was lifted to a height of 25,000
feet by a Boeing 747 airplane and then released, gliding back to
Edwards Air Force Base on its own accord.

On June 29, 1995, the American space shuttle Atlantis docked
with the Russian space station Mir to form the largest man-
made satellite ever to orbit the Earth.

This historic moment of cooperation between former rival space programs was also the 100th human space mission in American
history.

At 11:38 a.m. EST, on January 28, 1986, the space shuttle
Challenger lifted off from Cape Canaveral, Florida, and
Christa McAuliffe is on her way to becoming the first
ordinary U.S. civilian to travel into space. McAuliffe, a
37-year-old high school social studies teacher from New
Hampshire, won a competition that earned her a place
among the seven-member crew of the Challenger.

Seventy-three seconds later, hundreds on the ground,
including Christa’s family, stared in disbelief as the
shuttle broke up in a forking plume of smoke and fire.

Nearly four decades after he became the first American to orbit
the Earth, Senator John Herschel Glenn Jr.was launched into
space again as a payload specialist aboard the space shuttle
Discovery on October 29, 1998.

At 77 years of age, Glenn was the oldest human ever to travel
in space. During the nine-day mission, he served as part of a
NASA study on health problems associated with aging.

Regular flights of the space shuttle began on April 12, 1981, with
the launching of Columbia from Cape Canaveral, Florida.
