Space Shuttle to Receive Emegency Repairs 427
Tycow writes "The BBC are reporting that
Discovery needs emergency repairs - dangling material has been spotted on the belly of the shuttle, and NASA are worried they could cause overheating on re-entry. 'Nasa is concerned the dangling material - called gap fillers - could cause part of the shuttle to overheat as it re-enters the atmosphere.The type of repairs being planned have never been conducted by astronauts on a spacewalk before.'"

The astronaut will be outside the orbiter standing in a foot restraint mounted to the end of the space station's robotic arm.

That's too high by a factor of about five. The National Priorities Project is claiming a total of $204.6 billion [costofwar.com], for a little under three years (which is to say, about a thousand days). Your number would see them spending a cool trillion in that time.
They're still spending way too much, of course, but let's not make up silly numbers.

The 'new' foam is only used on acreage foam. The hand sprayed/sculpted foam (which killed Columbia and produced the big scary chunk after SRB sep on the current flight) is still the old freon blown foam. This is very plainly spelled out in the CAIB report and recent NASA press releases.
This story is completely contradicted by the CAIB report - furthermore this graph/image [chron.com] plainly shows that NASA *has* been making progress in reducing foam shedding/tile damage caused by the 1998 switch to 'enviromentally friendly foam'.The real reason isn't because it's an emergency!

The real reason for this 'repair' is because this whole mission is to "test orbiter repair techniques" - and these virtually irrelevant pieces of gap filler provide an unexpected, but very fortunate opportunity to try a real repair technique out in a relatively safe and controlled fashion.
NASA doesn't yet know if it's even possible to have an astronaut perform repair-type work on the underbelly of the orbiter - they think it would be possible, but they have no hard data to say it can be done.
But these small bits sticking out give them the perfect excuse to go test it and get some real-world experience on the issue.
If it looks like the astronaut might damage some of the Thermal Protection System tiles down there, they'll just terminate the repair attempt and fly home as-is. If not, they'll demonstrate that astronauts can go under an orbiter and perform repair tasks down there safely and without harming the TPS.
But I'll bet you'll hear the popular press making too much out of this as usual...

It wasn't a danger with the Saturn 5 because it was a vertical stack without a fragile crew module on the side of the stack where it could be hit by debris. As long as it kept going up, there wasn't anything to worry about because the entire rocket would either end up at the bottom of the ocean, circling the Sun, crashed into/left on the Moon, or burned up in the atmosphere. The only part that had to face reentry heat was protected throughout the entire mission and only exposed in the last hour or two before entry.

What are you talking about?
The US lost seven astronauts durring the Apollo program alone:
Elliott See
Charles Bassett
Theodore Freeman
Clifton Williams
Virgil I. Grissom
Ed White
Roger B. Chaffee
We also lost several other astronauts who were working on other projects, includeding Michael J. Adams and Robert Henry Lawrence, Jr.
The US also came very close to killing:
The Apollo 13 crew (Jim Lovell, John Swigert & Fred Haise) both durring the launch, and the famous explosion.
The Apollo Soyuz Test Project crew (Deke Slayton, Thomas Stafford & Vance Brand)

Our species is trying to figure out how to do this. It's hard. It takes time and costs lives and great treasure. Fifty years from now some nameless mech will be strapped to the side of a cracked hull trying to patch a hole with a Shuttle derived glue gun.
Take the long view. It's easier on the blood pressure.
of manned flight versus unmanned.
There is no versus. Cassini is filling basements full of storage devices with Saturn and its moons. Deep Impact's primary objective was fulfilled only one month ago. In 2003, WMAP (and COBE before it) nailed the age of the universe to within a couple hundred million years. CLOVER and the Planck Surveyor will improve on this. Gravity Probe B is concluding its mission in August. NOAA-N launched in May. Spitzer (2003) and Chandra (1999) are both functioning well. Here is a page [nasa.gov] full of on-going unmanned missions you probably can't even identify.
GOES-N launches in 3 days. Mars Reconnaissance Orbiter is launching in 6 days. CALIPSO goes up next month. STEREO, ST5, GOES-O, AIM, THEMIS, Pluto New Horizons and Dawn are all launching in 2006. Phoenix launches in 2007.
There is no verses. We do BOTH. We have the means and we're using it, regardless of what fools like you think you know.
