Orbital ATK names next Cygnus after John Glenn
CAPE CANAVERAL, Fla. — Orbital ATK announced that it has named the next Cygnus spacecraft to be sent to the International Space Station after former astronaut and U.S. Senator John Glenn, who died on Dec. 8, 2016, at the age of 95.
The S.S. John Glenn will be launched during a 30-minute window that starts at 10:56 p.m. EDT March 19 (02:56 GMT March 20), 2017, atop a United Launch Alliance (ULA) Atlas V rocket. It will take about three days for the spacecraft to reach the ISS, where it will be captured by the station’s robotic Canadarm2 to be berthed to the Earth-facing port of the Unity module.
Orbital ATK names all of their ISS cargo freighters after former astronauts. The OA-7 mission is the second Cygnus to be named after a member of the original Mercury 7 astronauts, the previous was after Deke Slayton.
Other Cygnus have been named for George Low, Charles Fullerton, Janice Voss, Rick Husband, and Alan Poindexter, all of whom flew during the Space Shuttle program.
Glenn was born on July 18, 1921, in Cambridge, Ohio. He was a decorated combat veteran of both World War II and the Korean War; in 1959, he was selected by NASA as part of the U.S.’ first set of astronauts.
Rocketing into the history books on Feb. 20, 1962, Glenn became the first American to orbit the Earth. Riding a Mercury-Atlas rocket, his one-man Friendship 7 capsule orbited the planet three times before splashing down in the North Atlantic Ocean.
After resigning from NASA in 1964, he went on to run for a U.S. Senate seat from Ohio. However, an injury that year forced an early withdraw. He lost a close election for the same seat in 1970.
In 1974 he won his first election and served for 24 years. Glenn even had an unsuccessful bid for president in 1984.
While he was a Senator, he became the oldest person to fly in space at the age of 77 during Space Shuttle Discovery’s STS-95 mission, a record that has yet to be broken. In October 1998, he spent just over nine days orbiting Earth. He was also the only member of the original Mercury astronauts to fly on the Space Shuttle.
Having an internal volume of 950 cubic feet (27 cubic meters), the 21-foot (6.4-meter) long, 10-foot (3.1-meter) wide craft will carry some 7,700 pounds (3,500 kilograms) of supplies and experiments for Expedition 50 and future ISS crews.
Among the experiments on board is the third Saffire payload. This flame experiment is part of an ongoing series to study the effects of fire in microgravity. It is the largest flame-experiment in the history of space exploration.
Saffire-III will be remotely activated after the cargo portion of the mission concludes, some 90-days after arriving at the ISS. Once Cygnus is unberthed and moved a safe distance away from the outpost, the experiment will be performed and results downloaded via telemetry before re-entering Earth’s atmosphere.
Also on board the S.S. John Glenn is the Reentry Data Collection (RED-Data-2) flight recorder. It will provide data about the conditions the spacecraft will encounter during its destructive re-entry.
Finally, a NanoRacks deployer on the exterior of the spacecraft will release a number of CubeSats.
When it launches, the OA-7 Cygnus will be the third to use a ULA Atlas V. It will fly out of Cape Canaveral Air Force Station’s Space Launch Complex 41.
Derek Richardson has a degree in mass media, with an emphasis in contemporary journalism, from Washburn University in Topeka, Kansas. While at Washburn, he was the managing editor of the student run newspaper, the Washburn Review. He also has a blog about the International Space Station, called Orbital Velocity. He met with members of the SpaceFlight Insider team during the flight of a United Launch Alliance Atlas V 551 rocket with the MUOS-4 satellite. Richardson joined our team shortly thereafter. His passion for space ignited when he watched Space Shuttle Discovery launch into space Oct. 29, 1998. Today, this fervor has accelerated toward orbit and shows no signs of slowing down. After dabbling in math and engineering courses in college, he soon realized his true calling was communicating to others about space. Since joining SpaceFlight Insider in 2015, Richardson has worked to increase the quality of our content, eventually becoming our managing editor. @TheSpaceWriter
