Shuttle's Boosters Recovered in HD

Shuttle's Boosters Recovered in HD

NASA has released the first ever up-close, high-definition video of Kennedy Space Center's solid rocket booster (SRB) recovery ships retrieving SRB segments from the Atlantic Ocean following a space shuttle launch. The unprecedented video is from the launch of the most recent shuttle mission, STS-133, Discovery's final flight, on Feb. 24. Following each space shuttle launch, crew members of Liberty Star and Freedom Star pull the spent boosters out of the ocean and return them to Hangar AF at Cape Canaveral Air Force Station in Florida. Once they are processed, the boosters are transported to Utah, where they are refurbished and stored, if needed.

★ Space Shuttle Challenger Disaster - Short Documentary - HD

The Space Shuttle Challenger disaster occurred on January 28, 1986, when Space Shuttle Challenger (mission STS-51-L) broke apart 73 seconds into its flight, leading to the deaths of its seven crew members. My photos: https://plus.google.com/u/0/b/105656643463219506384/+aheli ★ The Largest Stars in the Universe | Infographic Animation ► https://www.youtube.com/watch?v=JqAJnrL27OY ★ The Most Astounding Fact - Neil deGrasse Tyson | Kinetic ►Typography https://www.youtube.com/watch?v=p2DXqJ7mjKY ★ TOP 10 - Best of Hubble Space Telescope - 2015 ► http://www.youtube.com/watch?v=Lmx19_0GX8o The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida at 11:38 EST (16:38 UTC). Disintegration of the vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff. The O-ring failure caused a breach in the SRB joint it sealed, allowing pressurized hot gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB attachment hardware and external fuel tank. This led to the separation of the right-hand SRB's aft attachment and the structural failure of the external tank. Aerodynamic forces broke up the orbiter. The crew compartment and many other vehicle fragments were eventually recovered from the ocean floor after a lengthy search and recovery operation. The exact timing of the death of the crew is unknown; several crew members are known to have survived the initial breakup of the spacecraft. The shuttle had no escape system, and the impact of the crew compartment with the ocean surface was too violent to be survivable. The disaster resulted in a 32-month hiatus in the shuttle program and the formation of the Rogers Commission, a special commission appointed by United States President Ronald Reagan to investigate the accident. The Rogers Commission found NASA's organizational culture and decision-making processes had been key contributing factors to the accident. NASA managers had known contractor Morton Thiokol's design of the SRBs contained a potentially catastrophic flaw in the O-rings since 1977, but failed to address it properly. They also disregarded warnings (an example of "go fever") from engineers about the dangers of launching posed by the low temperatures of that morning and had failed in adequately reporting these technical concerns to their superiors. What Rogers did not highlight was that the vehicle was never certified to operate in temperatures that low. The O-rings, as well as many other critical components, had no test data to support any expectation of a successful launch in such conditions. Bob Ebeling from Thiokol delivered a biting analysis: "[W]e're only qualified to 40 degrees ...'what business does anyone even have thinking about 18 degrees, we're in no man's land.'" As a result of the disaster, the Air Force decided to cancel its plans to use the Shuttle for classified military satellite launches from Vandenberg Air Force Base in California, deciding to use the Titan IV instead. Approximately 17 percent of Americans witnessed the launch live because of the presence of crew member Christa McAuliffe, the first member of the Teacher in Space Project, who would have been the first teacher in space. Media coverage of the accident was extensive: one study reported that 85 percent of Americans surveyed had heard the news within an hour of the accident. In memory of the crew of space shuttle Challenger. RIP The clip is from "When We Left Earth: The NASA Missions (2008)"

Strut Bar - Explained

Strut Bar - Explained

What is a strut bar? How does a strut bar work? What forces act on the strut bar through the suspension? A strut bar, or tower bar, connects the top strut towers together, in order to increase the rigidity of a vehicle by allowing both strut towers to react to compression and tensile forces. A strut bar plays a larger role for MacPherson strut vehicles, however it can still be important in vehicles with double wishbones as well for compensating vertical forces. Check out the strut bars from this video at: http://www.redline360.com/ Front Strut: http://www.redline360.com/megan-racing-strut-tower-bar-acura-integra-front-upper-MR-SB-HC8800FU Rear Strut: http://www.redline360.com/megan-racing-strut-tower-bar-acura-integra-rear-upper-MR-SB-HC88RU You may also want to know more about the suspension types discussed in this video.

What Is The Fuel Used In Spacecraft?

What Is The Fuel Used In Spacecraft?

The Space Shuttles large External Tank is loaded with more than 500,000 gallons of super-cold liquid oxygen and liquid hydrogen, which are mixed and burned together to form the fuel for the orbiters three main rocket engines. A rocket works by exchanging momentum. Both the mass of propellant and high velocity its exit from engine system give rocket momentum. It's a powerful fuel and it stores well, but it's also nasty stuff, involves prep time that slows down ground operations considerably. Since their invention by the chinese in 13th century, rockets have seen a substantial amount of development, although they still work on same principle. Rockets are propelled by expelling their burnt fuel at a very high speed. Here, the spacecraft is still in its cocoon form, gemini fuel cell section. Back in august 2013, nasa's michael gazarik, director of space 13 apr 2016 the launch is part air force's test program 2 (stp 2) mission.

What voyager 1 uses for fuel spacecraft? . With five solid boosters, the v 551 is most powerful of atlas rockets. S juno launched in august 2011 from cape canaveral, florida, aboard an atlas v 551 rocket. All current spacecraft use chemical rockets (bipropellant or solid fuel) for launch, though some (such as the pegasus rocket and spaceshipone) have used air breathing engines on their first stage 29 jul 2010 today, liquid hydrogen is signature fuel of american space program by other countries in business launching satellites. Smith, chief of the exploration vehicle project office at nasa's john h. The rocket operates in stages, so as it blasts juno into space, segments of fall off once they're burned out. The space shuttles used largely liquid hydrogen (and of course, loads other chemicals) plus oxygen most satellites orbiting the earth using hypergolic fuel oxidizer combinations (meaning they combust when contact each. What kind of fuel is generally used in rocket engines? Updated. Googleusercontent search. What is rocket fuel made of? are possible power sources for spacecraft? . New solar cells are currently being developed to work in conditions where the light intensity and temperatures low, meaning that powered spacecraft will be able operate 21 oct 2013 nasa's space transportation system (sts) vehicle, better known as shuttle, used two single engine solid rocket boosters (srb) stage 0, an engineless external tank providing propellant for three shuttle main engines (ssme) on orbiter 1, additional orbital 18 mar 2016 but over a long range mission, it can deliver 10 times much thrust per kilogram of fuel chemical. Liquid fuel rockets most commonly use liquid cells which are somewhat like batteries, storing power in the form of separated oxygen and hydrogen. It's a safe, stable substance that's relatively common even in space, but could also find great
