Video footage from a shuttle booster pack


chassis

Recommended Posts

Shame about all the bits of crap that fall off the rocket on sea impact and are lost to sea though.

 

True, but they still re-use the casings. Shuttle cut down costs tremendously by being so reusable: makes you realize how many rockets, most of which were bigger components, were burned up or simply left in space during previous space programs.

How can you still hear those sounds in space though? Or are the rockets still in the atmosphere?

 

They jettison at 150,000 feet which is like 28 miles (45 km - thanks google!) which is still in the stratosphere. The Shuttle would level off and orbit anywhere from 190 to 960 km depending on it's mission. I think anything in the thermosphere is considered "outer space" and the FAI definition of space is 100km, well above where these boosters start to fall.

question for people in the know:

 

Why does it speed up in the stratosphere but slows down immensely upon return into the lower levels of the atmosphere? I would have thought gravity gets stronger the closer you are to Earth...or is it because the lower atmospheric layers are so much "thicker"?

The lower levels of atmosphere are denser and have more resistance. Gravity has a terminal velocity which it wont exceed.

Most of the sounds are internal sounds made by the rocket itself, so since the camera is attached to the rocket it can travel through the body to the camera and into the mic. Although as Joshuatx said, there still is an atmosphere. Cant imagine anything else is making the sounds other than the rocket.

stuff like this makes me wish I was good at science :(

 

Its hardly too late now is it? I don't read books any more, all I read is articles or journals. So it just depends on which you find more interesting. A lot of the science to do with space is pretty straight forward. The irony of the phrase "Its not rocket science" is that rocket science is fundamentally simple. It's just the accuracy you need when peoples lives are at stake is pretty high, and you have to take into account every eventuality.

Yeah I think it's easy to be informed about science and it's applications - I think people who aren't cut out for college or even advanced high school math and science courses can still be highly intelligent in other areas and still very aware and knowledgeable about basic concepts. Like chassis said - it's just a matter of what you're doing and it's importance - a NASA engineer for a manned space mission is more qualified and knowledgeable than say, a kid circuit bending keyboards or a old guy fixing up an old car - but it doesn't make him inherently more intelligent or "less good" at science by a huge degree.

The mph thing is still weird though. I would have expected it to turn to 0 at the highest altitude, before it would fall down again. Instead it seems to behave more like an altitude meter. O_o

 

Also, Lucasarts? Who would have thought George would still be up to something good? ...indirectly
