Images and news stories shared by NASA are often the subject of false online claims and conspiracy theories, which we have written about in the past. Mr McCandless, who died in 2017, gave a number of interviews about his experiences during the space walk.Īs other fact checkers such as AP have written, manipulated versions of the iconic photo have been shared online in the past. Its maiden flight was on Ap11, and it completed nine missions before breaking apart 73 seconds after the launch of its tenth mission, STS-51-L 51+元9 on. Mr McCandless undertook the space walk in order to test what is known as a Manned Manoeuvring Unit, essentially a jetpack which allows astronauts to direct themselves in space while outside a spacecraft. Space Shuttle Challenger (NASA Orbiter Vehicle Designation: OV-099) was NASA’s second Space Shuttle orbiter to be put into service, Columbia having been the first.
The photo was taken by crew also on the space flight, alongside a video of the event. It shows astronaut Bruce McCandless II reaching his furthest point from the Challenger space shuttle during the first ever untethered space walk, described by NASA as an “extravehicular activity ”, in 1984. While the picture may seem hard to believe, it is a real photo published by NASA.
#CHALLENGER SPACE SHUTTLE CONSPIRACY FULL#
We have now turned our full efforts to the future, but will never forget our seven friends who gave their lives to America’s space frontier.’'Īsked when the Challenger families were told of the findings, Truly replied only ''over the past several days.A post on Facebook claims that a picture of an astronaut, untethered from a space shuttle and hovering above Earth, is fake. ''I believe their efforts have now closed this chapter of the Challenger loss. JUDITH RESNIK, CHALLENGER MISSION SPECIALISTBorn on April 5, 1949, Challenger mission sp. ''Many dedicated people, both from within NASA and from other agencies, have devoted long hours and many months, first to recover the Challenger crew module from the ocean floor, and then to examine all available evidence to establish the cause of death of the crew,’' Truly said. Are the crew members of 1986 Space Shuttle Challenger still alive5.
Truly also said NASA has been ''unable to determine positively’’ exactly what killed the Challenger astronauts, but he said ''it is possible, but not certain, that loss of consciousness did occur in the seconds following the orbiter breakup.’' ''The findings are inconclusive,’' said Kerwin, who said his investigative team concluded the forces of the Challenger breakup ''were probably not sufficient to cause death or serious injury.’' During the six-day mission, the seven-member crew was to deploy a large communications satellite, deploy and retrieve an astronomy payload to study Halley’s Comet, and the first teacher in space would conduct lessons for. The force of the crew compartment hitting the ocean, which was ''far in excess of the structural limits of the crew compartment or crew survivability levels,’' caused such destruction that the experts were unable to determine the precise cause of death, Kerwin said. A cloud of fire engulfed the space shuttle just 73 seconds after liftoff, at an altitude of some 46,000 feet (14,000 meters). The next flight, designated STS-51L, marked the 25 th in the program and the 10 th for space shuttle Challenger.
The cabin would have hit the water at about 207 mph, creating a force equal to about 200 times that of gravity, he said. An old conspiracy theory falsely claims that the Challenger NASA space shuttle never blew up and its crew is still alive. He said the damage to the compartment from the impact was so great that ''no positive evidence for or against in-flight pressure loss could be found.’' ''Medical analysis indicates that these accelerations are survivable, and that the probability of major injury to crew members is low,’' it said.Īn analysis showed that if the crew members lost consciousness due to a loss of pressure, they would not have had time to revive as the crew compartment fell into denser air at lower altitudes, Kerwin said. The crew cabin tore loose at 45,000 feet, arced upward to about 65,000 feet, and then began a 2-minute, 45-second plunge to the Atlantic Ocean, Kerwin said.Īcceleration forces at the time of the breakup were estimated at 12 to 20 Gs for about 2 seconds, the report said.
Investigators say the accident occurred when a joint in a solid rocket booster failed and caused superheated gases to burn through the external fuel tank containing liquid hydrogen and liquid oxygen, triggering the explosion.
