Crossed Kármán Line

STS-41-D (Discovery)

The maiden voyage of the Space Shuttle Discovery. A June 26th launch attempt ended at T-6.4 seconds after two of the three Shuttle main engines had started to ignite. The pad abort triggered a hydrogen fire under Discovery, damaging the Space Shuttle. The abort led to major improvements in Shuttle abort safety guidelines and procedures and forced a two month delay to the flight, during which NASA cancelled STS-41-F and transferred its payload to this mission. After launch, the crew deployed three communications satellites for the U.S. (2) and Canada (1) and tested solar array technology. The flight marked the first time a company commercially sponsored an employee to fly on the Space Shuttle to perform one of its experiments.

The first reusable launch and landing spacecraft, the Space Shuttle began a new chapter of human space exploration. It launched like a rocket but landed on a runway like a plane. Shuttle crews deployed dozens of commercial satellites and two interplanetary probes to Venus and Jupiter. The Shuttle served as a mini space station and hosted hundreds of biomedical, psychological, physiological, materials science, and physics experiments that have directly benefited life on Earth. The five flight-worthy Shuttles -- Columbia, Challenger, Discovery, Atlantis, and Endeavour -- flew 135 missions over 30 years. The Shuttles helped construct the Russian Mir space station and brought nearly 80% of the International Space Station to orbit. Shuttles also deployed and serviced the Hubble Space Telescope.

STS-51-D (Discovery)

This mission deployed a Canadian communications satellite and tried to deploy a U.S. satellite, but an issue forced an unscheduled spacewalk to try to manually start the satellite's post-deployment sequence. The crew eventually had to bring the satellite back to Earth for repair. During landing Discovery blew a tire, leading NASA to suspend all Florida Space Shuttle landings until nose gear steering and improved braking could be added.

STS-61-B (Atlantis)

This mission deployed three satellites for Australia, Mexico, and the U.S., and took the first Mexican citizen to space. Two spacewalks proved assembling large, pre-formed structures in space was possible, though their shape was crucial -- a key to the eventual construction of the International Space Station. At launch, this became the fastest turnaround between flights of any rocket or spacecraft to date; Atlantis launched for a second time just 54 days after her first mission.

Jerry L. Ross (born January 20, 1948, in Crown Point, Indiana) is a retired USAF Colonel, mechanical engineer, and NASA astronaut who holds the joint world record for most space shuttle launches—seven missions between 1985 and 2002—and is second all-time in both total EVAs (9) and spacewalk duration (about 58 hours) . A Purdue alumnus (B.S. 1970, M.S. 1972), Ross flew combat aircraft, conducted ramjet and B‑1 bomber flight-test projects, and later served at Johnson Space Center from shuttle payload officer to Chief of the Vehicle Integration Test Office . Selected as an astronaut in 1980, his missions included STS‑61B, STS‑27, STS‑37, STS‑55 (payload commander), STS‑74 (Mir docking), STS‑88 (first ISS assembly), and STS‑110 (ISS truss installation), accumulating over 1,393 hours in space . After retiring from NASA and the Air Force (2012), Ross authored the memoir Spacewalker (2013) and a forthcoming children’s book, Becoming a Spacewalker, further inspiring future explorers.

STS-55 (Columbia)

The second German-sponsored Space Shuttle flight saw 88 experiments from 11 nations taken to orbit.  A March launch attempt ended at T-3 seconds with an on-pad abort and emergency shutdown of Columbia's engines after a failure was detected.

STS-88 (Endeavour)

The first International Space Station construction mission. Endeavour launched the Unity module for the U.S. and met up with the first Russian station module, Zarya ("sunrise"), linking the two modules together in an historic partnership.

STS-110 (Atlantis)

Atlantis delivered the S0 truss to the International Space Station, the backbone of the international outpost. Jerry Ross became the first person to launch to space seven times.

STS-27 (Atlantis)

This Atlantis mission almost didn't make it back to Earth. During launch, debris from the Solid Rocket Booster critically damaged 700 of Atlantis' heat shield tiles, nearly leading to a burn-up and the loss of Atlantis and her seven-member crew during reentry and landing. The classified nature of the mission prevented NASA from doing extensive damage assessment during orbit.

STS-37 (Atlantis)

Atlantis' crew deployed the Compton Gamma Ray Observatory after an unplanned spacewalk to unstick the Observatory's communications antennas. The crew also practiced moving equipment and people around a future space station using a small mock-up in the Shuttle's payload bay.

STS-74 (Atlantis)

The second Shuttle-Mir docking saw Atlantis deliver a pair of solar arrays and the Russian-built Mir Docking Module to the station.

STS-9 (Columbia)

A dedicated science flight co-sponsored by NASA and ESA, STS-9 marked the first time an ESA/West German astronaut reached space and the first time a non-American launched on a U.S. mission.

STS-40 (Columbia)

This mission was the fifth flight of Spacelab and the first one dedicated specifically to biological research. It marked the first time three women flew together on a single mission.
