CAPE CANAVERAL, Fla. – The second stage of the Saturn 1B booster for the United States mission on the Apollo Soyuz Test Project was mated with the Saturn 1B first stage in the Kennedy Space Center's Vehicle Assembly Building today. Mating was completed at 9:50 a.m. The U. S. ASTP launch with mission commander Thomas Stafford, command module pilot Vance Brand and docking module pilot Donald Slayton is scheduled at 3:50 p.m. EDT July 15. The first international crewed spaceflight was a joint U.S.-U.S.S.R. rendezvous and docking mission. The Apollo-Soyuz Test Project, or ASTP, took its name from the spacecraft employed: the American Apollo and the Soviet Soyuz. The three-man Apollo crew lifted off from Kennedy Space Center aboard a Saturn IB rocket on July 15, 1975, to link up with the Soyuz that had launched a few hours earlier. A cylindrical docking module served as an airlock between the two spacecraft for transfer of the crew members. Photo credit: NASA

It also includes the three-part hatch to the spacecraft itself, the first time any part of the Apollo 1 spacecraft has been displayed publicly. A version of the hatch after it was redesigned is also showcased as an example of improvements NASA made throughout the agency and to the Apollo spacecraft that would later carry astronauts to the moon.

A display case dedicated to astronaut Roger Chaffee is shown inside the new tribute to the crew of Apollo 1 who perished in a fire at the launch pad on Jan. 27, 1967, during training for the mission. Gus Grissom, Ed White II and Chaffee were lost during the fire.

CAPE CANAVERAL, Fla. – The Apollo Soyuz Test Project Saturn IB launch vehicle thundered away from KSC’s Launch Complex 39B at 3:50 p.m. today. Aboard the Apollo Command Module were ASTP Astronauts Thomas Stafford, Vance Brand and Donald Slayton. The astronauts will rendezvous and dock with a Soyuz spacecraft, launched this morning from the Baikonur launch facility in the Soviet Union, carrying Soviet cosmonauts Aleksey Leonov and Valeriy Kubasov. The first international crewed spaceflight was a joint U.S.-U.S.S.R. rendezvous and docking mission. The Apollo-Soyuz Test Project, or ASTP, took its name from the spacecraft employed: the American Apollo and the Soviet Soyuz. The three-man Apollo crew lifted off from Kennedy Space Center aboard a Saturn IB rocket on July 15, 1975, to link up with the Soyuz that had launched a few hours earlier. A cylindrical docking module served as an airlock between the two spacecraft for transfer of the crew members. Photo credit: NASA

Flowers are placed in front of the Space Mirror Memorial at the Kennedy Space Center Visitor Complex after this year’s Day of Remembrance ceremony. The memorial, a 42-foot-high by 50-foot-wide granite monument, displays the names of the fallen astronauts from Apollo 1, space shuttles Challenger and Columbia, as well as others who have lost their lives while on NASA missions or in training. Each year, Kennedy employees and guests gather with others throughout NASA to honor those astronauts who have fallen in the pursuit of space exploration.

What better way to mark 50 years of rocket engine testing than with a rocket engine test? Stennis Space Center employees enjoyed a chance to view an RS-68 engine test at the B-1 Test Stand on April 19, almost 50 years to the day that the first test was conducted at the south Mississippi site in 1966. The test viewing was part of a weeklong celebration of the 50th year of rocket engine testing at Stennis. The first test at the site occurred April 23, 1966, with a 15-second firing of a Saturn V second stage prototype (S-II-C) on the A-2 Test Stand. The center subsequently tested Apollo rocket stages that carried humans to the moon and every main engine used to power 135 space shuttle missions. It currently tests engines for NASA’s new Space Launch System vehicle.

KENNEDY SPACE CENTER, FLA. -- In a cavalcade of veteran Apollo and Mercury astronauts, John Glenn rides in the back of a Corvette driven by Al Worden. On Feb. 20, 1962, John Glenn piloted the Mercury-Atlas 6 "Friendship 7" spacecraft on the first U.S. manned orbital mission. Worden was command module pilot for Apollo 15, July 26-Aug. 7, 1971. The astronauts were part of the World Space Expo, an event to commemorate humanity's first 50 years in space while looking forward to returning people to the moon and exploring beyond. Commemorating humanity's first 50 years in space while looking forward to returning people to the moon and exploring beyond, the expo showcased various panels, presentations and educational programs, as well as an aerial salute featuring the U.S. Air Force Thunderbirds, U.S. Air Force F-22 Raptor, U.S. Navy F-18 Super Hornet, U.S. Air Force F-15 Eagle, the P-51 Mustang Heritage Flight, and the U.S. Air Force 920th Rescue Wing, which was responsible for Mercury and Gemini capsule recovery.
