The astronauts, part of the original class of seven astronauts chosen by NASA, were taking part in a question-and-answer session with the media as part of events celebrating 50 years of Americans in orbit, an era which began with John Glenn's Mercury mission MA-6, on Feb. 20, 1962. Glenn's launch aboard an Atlas rocket took with it the hopes of an entire nation and ushered in a new era of space travel that eventually led to Americans walking on the moon by the end of the 1960s. Glenn soon was followed into orbit by Carpenter, Walter Schirra and Gordon Cooper. Their fellow Mercury astronauts Alan Shepard and Virgil "Gus" Grissom flew earlier suborbital flights. Deke Slayton was grounded by a medical condition until the Apollo-Soyuz Test Project in 1975.

At 9:47 a.m. EST, the Atlas launch vehicle lifted the spacecraft into orbit for a three-orbit mission lasting four hours, 55 minutes and 23 seconds. Glenn and his spacecraft were recovered by the destroyer Noa just 21 minutes after landing in the Atlantic near Grand Turk Island, to successfully complete the nation's first manned orbital flight.

The space shuttle Discovery lifts off Launch Pad 39B to begin a nine-day mission in Earth-orbit. Launch was at 2:19 p.m. EST, Oct. 29, 1998. Onboard were Curtis L. Brown Jr., Steven W. Lindsey, Scott F. Parazynski, Steven K. Robinson, Pedro Duque, United States Senator John H. Glenn Jr. and Chiaki Naito-Mukai. Duque is a mission specialist representing the European Space Agency (ESA) and Mukai is a payload specialist representing Japan's National Space Development Agency (NASDA). Glenn, making his second spaceflight but his first in 36 years, joins Mukai as a payload specialist on the mission.

Glenn Jr., senator from Ohio, is prepared by closeout room crew members Danny Wyatt (left to right), Carlous Gillis, Jim Kelly and Travis Thompson for entry into the Space Shuttle Discovery for his second flight into space after 36 years. The STS-95 mission, targeted for launch at 2 p.m. EST on Oct. 29, is expected to last 8 days, 21 hours and 49 minutes, and return to KSC at 11:49 a.m. EST on Nov. 7.
