Andy,
I'm just yanking your chain ![[Wink]](wink.gif) , of course it flies over England.
Here are some amazing facts about the Space Shuttle Main Engines...... These promises have been lived up to and just for Greg.
______________________________________________
Rocketdyne's Space Shuttle Main Engine operates at greater temperature extremes than any mechanical system in common use today. The liquid hydrogen fuel is -423 degrees Fahrenheit, the second coldest liquid on Earth. When the hydrogen is burned with liquid oxygen, the temperature in the engine's combustion chamber reaches +6000 degrees Fahrenheit - that's higher than the boiling point of Iron.
The maximum equivalent horsepower developed by the three SSMEs is just over 37 million horsepower.
The energy released by three of Rocketdyne's Space Shuttle Main engines is equivalent to the output of 13 Hoover Dams.
Although not much larger than an automobile engine, the SSME high-pressure fuel turbopump generates 100 horsepower for each pound of its weight, while an automobile engine generates about one-half horsepower for each pound of its weight.
Even though Rocketdyne's SSME weighs one-seventh as much as a locomotive engine, its high-pressure fuel pump alone delivers as much horsepower as 28 locomotives, while its high-pressure oxidizer pump delivers the equivalent horsepower for 11 more.
If water, instead of fuel, were pumped by the three Space Shuttle Main Engines, an average family-sized swimming pool could be drained in 25 seconds.
The SSME high-pressure fuel turbopump main shaft rotates at 37,000 rpm compared to about 3,000 rpm for an automobile operating at 60 mph.
The discharge pressure of an SSME high-pressure fuel turbopump could send a column of liquid hydrogen 36 miles in the air
__________________________________________
They forgot to mention that the turbopumps go from stand still to 37,000 rpm in less than two seconds! Now thats really pickin up steam in a hurry ![[Eek!]](eek.gif) .

Hello there all
Good morning Afternoon and evening…
Mark; that was some wind up I really fail for that one, you Space monkey.
Hi there Darryl are you watching the updates via the NASA television, man that imagining was totally indispensable and out of this world, I felt like the wild coyote…
You bet she’s up wow that is one brave commander they have there, Eileen bring the Discovery and the rest of the crew back home safely and God Speed Discovery. ![[beer]](graemlins/beer.gif)
Joe, man your mind is warped factor 2, Let the ISS burn-up blow up planets, gentlemen, no more Star Wars for that guy….
I’m going stay watching until (Discovery STS-114) touchdowns, by the way where is she landing home port, or out in the desert the dry lake in California.
Bill Readdy Associate Administrator of the Space Operations Mission Directorate
Said today at the NASA press conference
“Your can never let down your guard” (Bill Readdy) 26th July 2005 said this today.
Bill Readdy as fly several missions in the past
(Bill Readdy) was first on (Discovery STS-42) as a Mission Specialist 3 Launch Jan. 22, 1992.
Again on (STS-51 Discovery) serving as Pilot Launch September 12, 1993.
And on (STS-79 Atlantis) was the commander of the Space shuttle Launch September 16, 1996
You can watch updates on the mission of STS-114 return to flight live via NASA television.

As well as, the (J-Tracking) for the ISS international space station
http://science.nasa.gov/temp/StationLoc.html
Also the (J-Tracking for Discovery STS-114)
http://science.nasa.gov/temp/ShuttleLoc.html
PS, Mark, why man you should this to your interests and hobbies, and why on earth are you not working for NASA man you blow me away.
I’m wondering what other cameras they have onboard (Discovery STS-114) any IMAX cameras! ![[thumbsup]](graemlins/thumbsup.gif)
