On June 2, 1984 Discovery's flight readiness firing (FRF) was successfully performed at the Kennedy Space Center in Florida.
The flames of the SSME firing, an immense exhaust cloud escaping from the under the launch pad, and the retracted rotating service structure (RSS) are visible in the view. Six days earlier the firing countdown was halted inside the T minus 10 (T-10) second mark, just prior to SSME ignition, due to a problem in SSME number 2 propellant bleed valve. The approximately 22 second firing was conducted to evaluate the performance of various components of OV-103, external tank (ET) and solid rocket boosters (SRBs), as well as the launch facilities and support equipment which will be used during the launch of STS-26.
After 39 missions, 148,221,675 miles traveled and nearly 27 years, Discovery completed its final mission on March 9, 2011.
