space shuttle endeavour returns to earth

The Hubble Space Telescope Orbital Systems Test provided an on-orbit test bed for hardware that will be used during the third Hubble servicing mission. Medical research during the mission included a battery of tests on Payload Specialist Glenn and Mission Specialist Pedro Duque to further research how the absence of gravity affects balance and perception, immune system response, bone and muscle density, metabolism and blood flow, and sleep. The crew also released the Spartan free-flying satellite to study the sun and the solar wind in a research effort to help scientists better understand a phenomenon that sometimes can cause widespread disruptions of communications and power supplies on Earth. In addition to a variety of medical and material research, the crew released the Petite Amateur Naval Satellite, or PANSAT, to test innovative technologies to capture and transmit radio signals that normally would be lost because the original signals were too weak or contained too much interference. The scientific research mission also returned space pioneer John Glenn to orbit – 36 years, eight months and nine days after he became the first American to orbit the Earth.Ī slate of more than 80 experiments filled the nearly nine days in space. The toilet on board the SpaceX capsule was broken, forcing the astronauts to wear diapers for their 10-hour return. The primary objectives of STS-95 included conducting a variety of science experiments in the pressurized SPACEHAB module, the deployment and retrieval of the Spartan free-flyer payload, and operations with the Hubble Space Telescope Orbiting Systems Test (HOST) and the International Extreme Ultraviolet Hitchhiker payloads being carried in the payload bay. The crew faced one final challenge on their journey back to Earth. Managers decided not to deploy the chute upon landing.

Following main engine start, but prior to booster ignition, the drag chute compartment door fell off, but posed no problem for the mission. The nine-day mission supported a variety of research payloads, including experiments designed to investigate similarities between aging and the side effects of space flight. On this flight, Glenn became the oldest person to fly in space. Once the aircraft cleared the area, the RSO gave the all clear signal and the countdown proceeded. The crew of space shuttle Discovery mission STS-95, including John Glenn. Once the count picked up and the Orbiter Access Arm was retracted, the Range Safety Officer (RSO) requested a hold at T-5 minutes due to aircraft in the restricted air space around KSC. The countdown proceeded to T-9 minutes, but was held an additional 8.5 minutes while the launch team discussed the status of a master alarm heard during cabin leak checks after hatch closure. Mission Duration: 9 days, 19 hours, 54 minutes, 2 secondsĪt 12:30 p.m., the hatch was closed with crew inside the space shuttle Discovery, just as President Bill Clinton’s Air Force One plane touched down at the Cape Canaveral Air Station skid strip. ET splashdown off the coast of Jacksonville, Florida, returning four Crew-6 astronauts to Earth.

Landing Site: Kennedy Space Center, Florida 4: SpaceX's Crew Dragon Endeavour successfully returned to Earth for a 12:17 a.m.
