STS-133 The Final Launch of Space Shuttle Discovery including T-5 hold
This video includes clips starting at L-28 minutes showing the computer problems, additional T-5 hold added to the count, Go/No-Go statuses and ascent information for OV-103 or Space Shuttle Discovery. Launch was on Feb 24th, 2011 and this is the last time Space Shuttle Discovery will ever fly.

Space shuttle Atlantis was moved Thursday, Sept. 4, from the Vehicle Assembly Building to Launch Pad 39A at NASA's Kennedy Space Center, Fla., for its upcoming mission to service the Hubble Space Telescope. The move is referred to as «rollout.» Now that the shuttle is in launch position, Atlantis' crew will arrive at Kennedy on Sept. 21 to participate in a full launch dress rehearsal, known as the terminal countdown demonstration test, scheduled for Sept. 22-24. Atlantis is targeted to launch Oct. 10. During the 11-day STS-125 mission, the shuttle's seven astronauts will install two new instruments in Hubble, as well as replace the Fine Guidance Sensor. Atlantis' crew members are Commander Scott Altman, Pilot Gregory C. Johnson and Mission Specialists John Grunsfeld, Mike Massimino, Megan McArthur, Andrew Feustel and Michael Good.

Engineering Connections (Richard Hammond) — Space Shuttle | Science Documentary | Reel Truth Science
Richard Hammond reveals the engineering connections in NASA's Space Shuttle — the world's first re-usable space craft. He goes backstage at Kennedy Space Centre, in Florida, to discover how an organ pump, tram tracks, a WWII anti-sonar device, a camera iris and a cannonball all helped create the most technologically advanced machine ever engineered by man. Conceived in the early 1970's as the successor to the Apollo Moon missions, the Shuttle is a delivery system, designed to transport payloads such as the Hubble Telescope, and most of the International Space Station, into orbit, and return for its next cargo. The delivery van is the Orbiter — what most people call the Shuttle — which is mated with a huge external fuel tank and rocket boosters which are all jettisoned. Surviving the huge destructive forces of travelling to space and returning in usable form called for ingenious engineering compromises. The Shuttle is a rocket for the first part of its life, then morphs into a plane for the return journey.

Emergency Egress Slidewire Baskets Released for the Final Time
At Launch Pad 39A at NASA's Kennedy Space Center in Florida, the seven slidewire baskets travel down to the ground for the final time after being released by technicians from the 195-foot level. The system of seven slidewire baskets at launch pads A and B provided an escape route for astronauts and personnel inside the orbiter or on the orbiter access arm. The baskets are suspended from slidewires that extend from the pad's Fixed Service Structure to a landing zone 1,200 feet to the west. Each basket could hold up to three people. A braking system catch net and drag chain slowed and then halted the baskets sliding down the wire at approximately 55 miles per hour in about half a minute.
Here’s a fun question that not only have I myself asked, but I get asked fairly often, why do we hear a call out like “roger roll” or “roll program complete” at which point we can see the rocket rotate or roll on its X axis…
The best example of this was the Space Shuttle which had a very obvious and dramatic roll program. As soon as it cleared the tower, you can see it making a very impressive and sometimes scary looking roll.
Now a maneuver like this makes sense when a vehicle is asymmetrical like the Space Shuttle, but why do cylindrical rockets like the Saturn V, Titan, Atlas, Delta IV etc etc even bother doing a roll?
Can’t rockets just tip over in whatever direction they need to go? Do a little pitch here, a little yaw there just as long as the pointy end is going the direction it’s intended to go, who cares which side of the rocket is facing the Earth and which side is facing space… right?
So today we’ll first define the pitch, yaw, roll and their corresponding axis on a rocket, then we’re going to dive into why a rocket rolls in the first place, take a look at launch azimuths and their relationships to trajectories and we’ll look at some unique solutions to orientations including some rockets that don’t roll on ascent to align with their trajectory.

Why doesn't the sound of a rocket launch kill you?
During a rocket launch, the sound energy produced by the engines is strong enough to seriously damage anything in close proximity. So how do NASA get around this problem? This video looks at the methods NASA and the Russians use to reduce the sound energy during a rocket launch.

The day before the first launch attempt of Endeavour on STS-134, I and a coworker went out to LC39A to document the placement of pressure, heat, and temperature sensors on the SRB side of the main flame deflector inside the flame trench. This video gives an idea of what conditions are one day before a shuttle launch. The dripping water that you hear is from the water deluge system which is filled and primed to douse the launch pad at liftoff for sound suppression and heat mitigation.
Producing 500,000 pounds of thrust from a package weighing only 7,500 pounds, the Space Shuttle Main Engines are one of the shining accomplishments of the shuttle program. The success did not come easily, though.
