4.5 Gs for 4 mins.. I wonder how that would feel.
Poor bastard

The centrifuge training would have prepared them for that, but still bloody uncomfortable for 4 mins

doesnt the earth have a field of radiation around it? wouldnt the spacemen who flew in a rocket through that radiation field have died from radiation poisioning?

From the Wiki link..
"A satellite shielded by 3 mm of aluminium in an elliptic orbit (200 by 20,000 miles) passing through the radiation belts will receive about 2,500 rem (25 Sv) per year. Almost all radiation will be received while passing the inner belt."

http://en.wikipedia.org/wiki/R%C3%B6...equivalent_man

"An acute whole-body dose of under 50 rem is typically subclinical and will produce nothing other than blood changes. 50 to 200 rem may cause illness but will rarely be fatal. Doses of 200 to 1,000 rem will probably cause serious illness with poor outlook at the upper end of the range. Doses of more than 1,000 rems are almost invariably fatal."

2500 rems / 365 = 6.8 rems per 24hr period.

So yes, while the Van Allen Belt is dangerous, it's hardly life threatening while passing through for very short periods of time, and while protected within a space craft.

Humans spend ~6 days in transit to and from the Moon. Much of the journeys were not within either the inner or outer belt.

Ever wonder how the Saturn V abort system worked?



http://en.wikipedia.org/wiki/Launch_escape_system

Great quality video footage here of the Orion testing. Apollo similar.

Cool...

But seriously the yanks have dropped stupid amounts of cash on space.

At the end of the Apollo space program in 1973, it was said to have cost about US$25 Billion.
Yep, lots. ..and the main/only reason why it's never been revisited.

http://en.wikipedia.org/wiki/Apollo_program

"In 2009, NASA held a symposium on project costs which presented an estimate of the Apollo program costs in 2005 dollars as roughly $170 billion. This included all research and development costs; the procurement of 15 Saturn V rockets, 16 Command/Service Modules, 12 Lunar Modules, plus program support and management costs; construction expenses for facilities and their upgrading, and costs for flight operations."

Sure, the program wasn't free but the technological breakthroughs that were made were massive. Just like wartime, focussed, forced development reaps incredible benefits.
There is a very good reason the term "Space Age Technology" exists.

Kidney dialysis machines
Computer-Aided Tomography (CAT) scan
Magnetic Resonance Imaging (MRI)
Freeze-dried food
Cordless power tools & appliances
Corningware.
Tempur foam
Teflon--actually all kinds of plastics.
New techniques for machining and casting exotic metals like magnesium and titanium.
Carbon fiber epoxy, and other composite materials
CNC machining
Microwave communications
All kinds of telemetry
Huge improvements in photovoltaics (solar cells to generate electricty)
Solid lubricants
Solid state memory (RAM and ROM)
Developments in Lasers and Robotics
Enormous advances in astronomy because of the Hubbell Space telescope
Satellite photography that helps with everything from land development to monitoring changes in global climate.
Disposable diapers
Rotary blood pump
Fiber optics
Satellite dish
Bar codes
Ear thermometer
Fire-resistant fabrics
Smoke detector
Thermal gloves and boots

I am sure there is plenty there to recover $25 Billion and probably $170 billion and then some.

Apollo 11 launch with altitude and velocity data.

http://www.youtube.com/watch?v=F0Yd-GxJ_QM

Note when the Saturn V is about 2:20mins into flight, it's already lifted it's ~3,000,000Kg self to an altitude of 45Kms and is moving at 2000mtrs/sec.
Pretty impressive numbers.

BTW, 2000 m/s is 7200kph. Vertically!

Steve,
When I was told you missed dyno day coz you had to work I asked what work you did and was told you pour concrete slabs or something like that. My reply was I thought you were a rocket scientist.
I think I was right !

Cheers,
Fran.

Mad scientist might be a more suitable title.

At 402 meters of altitude, the Saturn V has already covered the 1/4 mile in a lame 18 seconds, but at 112MPH!
3mil Kgs straight up. Still impressive.

I love the hoaxer's excuse "They didn't have the technology back then".

Saw this hoax video where these morons are talking about duplicate rocks in NASA's own photos. (see @ 2:00mins) http://www.youtube.com/watch?v=sDdzNSXDaRI
The narator deliberately does not tell the viewer that it's a collage of several images that make up one picture. If they showed you the entire image, it's as obvious as a dog's balls that it's one picture made up of several. The cross-hairs clearly point it out also.
There is no way they could have missed that and if they did, these are the big-brains calling foul???
Seriously, what's their motive? They went ahead and made this documentary and call this image hoax evidence?
That's Comedy-Gold Jerry!

I have that book! Here's the full image.. See for yourself.

According to both a 1995 Time poll and a 1999 Gallup poll, about six per cent of Americans do not believe that 12 astronauts walked on the moon.

I'm sure it's more than 6%.. It's 37% in this thread's poll.
