    The cause of the disaster was the failure of the primary and secondary O-ring seals in a joint in the right Space Shuttle Solid Rocket Booster (SRB). The record-low temperatures on the morning of the launch had stiffened the rubber O-rings, reducing their ability to seal the joints.

    The Space Shuttle Solid Rocket Booster (SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. [1] A pair of them provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent.

    en.wikipedia.org/wiki/Solid_rocket_booster

    A solid rocket booster (SRB) is a solid propellant motor used to provide thrust in spacecraft launches from initial launch through the first ascent. Many launch vehicles, including the Atlas V , [ 1 ] SLS and Space Shuttle , have used SRBs to give launch vehicles much of the thrust required to place the vehicle into orbit.

    The Space Shuttle solid rocket booster field joint assembly (from the Rogers Commission report) The commission found that the immediate cause of the Challenger accident was a failure in the O-rings sealing the aft field joint on the right solid rocket booster, causing pressurized hot gases and eventually flame to "blow by" the O-ring and ...

    Immediately after the failure, President Ronald Reagan convened the Rogers Commission to determine the cause of the explosion. The failure of an O-ring seal on the starboard Solid Rocket Booster (SRB) was determined to have caused the shuttle to break up in flight. Space Shuttle flights were suspended for 32 months while the O-rings and other ...

    The investigation found that cold weather conditions caused an O-ring seal to fail, allowing hot gases from the shuttle's solid rocket booster (SRB) to impinge on the external propellant tank and booster strut. The strut and aft end of the tank failed, allowing the top of the SRB to rotate into the top of the tank and causing it to explode.

    The mission ended in disaster following the destruction of Challenger 73 seconds after lift-off, because of the failure of an O-ring seals on Challenger ' s right solid rocket booster, which led to the rapid disintegration of the Space Shuttle stack from overwhelming aerodynamic pressures.
