"The failure of Genesis was tied to a badly designed placement of deceleration sensors, a design flaw which Stardust is apparently free from"
While it's premature to call Genesis a "failure" it certainly did not meet specs. There was a very interesting session at the AGU in SF from the Genesis team
on what science they are doing and where they are going with their future research. No doubt everyone would have enjoyed a successful capture but even with the Utah desert impact there seems to be significant samples available for scientific study.
How many "micro$oft sucks" or "SCO is evil" or "Google is awesome" posts do we see all of the time? If this thing goes through there probably isn't one/.er who is safe.
Only in the exploration group would this sound like a good idea. 50K? Are they serious. So they are going to pull together a panel of experts, drag them into downtown DC for a few days, put them up in hotel rooms, pay them for food, cabs, etc...(at a total cost of what, around 2K per person.. given a panel of 10... 20K not including salary that also must be paid by someone, usually NASA as well) Then this group sits around and debates the merits of the 100+ proposals they receive. A winner is chosen and gets a check for 50K. The visionaries institution takes their cut (say 50%) and the winner is left with 25K. Take that 25K and spread it out over the 3 or 4 people involved in the proposal and each gets what? Around 8K. And exactly what are you suppose to do with 8K? Well, sounds to me like spend it on writing another proposal (phase 2). And in the end how much was spent on overhead during this process? You guessed it, every single penny.
While your doctor might be able to diagnose a problem would you pay him $60 to try to intercept a pass? (well OK, I just might) but seriously. There are very few people with the physical skills to intercept a pass and there are far more people with the skills to diagnose a problem with your prostate.
Once life gets tough enough that people wont shell out the cash for professional sports then the salary for these players will go down fast.. Supply and demand, just the way it should be.
"This reminds me of those who need to print out hard copies of material in order to study it properly."
Add me to that list. I peer review all of the time and when I want to study an article "properly" I always print a copy of it. I highlight, make notes, spew comments, criticize the author, etc.... It's essential that in my first pass of an article I have a hard copy of the paper, a pencil with plenty of lead, a spell checker, and an internet connection.
I would wager that the number of dick-head motorists is about the same as the number of dick-head cyclists.
I go around a tight curve going 40 when the speed limit is 25 and right in front of me is a dude on a bike, right in the middle of the road. Now sure, I was going too fast, but exactly what is this idiot trying to prove? When my bumper hits his tire he looses, period. OK, sue me, throw me in the can, but biker dude is dead and who is at fault for that? Well he is? Or I am? But at that point does it even matter?
The roads are designed for cars, not bikes.
Bikers are jeopardizing their lives every time they ride on the road. Regardless of this being right or wrong it's accurate.
Way too many cyclists have this "I have the right:" philosophy and it's dangerous. When I pull into the grocery store and take my kids out I don't just let them run through the parking lot, even though they have the "right" to do so. I make damn sure I hold their hand and try to explain to them that the cars are not looking out for them.
Far too many cyclists simply assume that the motorist will see them and do the appropriate thing. Most of the time this is exactly what happens, sometimes something else happens. The blame for the problem is equally shared between the cyclist and the motorist.
They are both given a deltaV, one + and the other -. They move apart at something like 20 deg/year, one leading the Earth and the other trailing the Earth.
"Also, what kind of instruments do these have?"
The spacecraft have a pretty broad suite of instruments, in situ energetic particles, fields and waves plus coronagraphs for taking pictures of coronal mass ejections.
One of the problems we have with our pictures of CMEs right now is that they are all taken from Earths orbit, we have never had a side shot of a CME that is going to hit the earth. It will be excellent to have a time sequenced image of the CME, then have that same structure impact the Earth with a full suite of instruments measuring the density, temperature, velocity, etc....

"In fact there have been many people for years that have argued that the manned program...took way too much of the NASA budget..."
And they would be absolutely correct. It does not take a rocket scientist to add up the number of peer-reviewed scientific/engineering papers (an indication of progress) for each mission, manned and unmanned alike, and compare the statistics. The science missions always produce many orders of magnitude more papers. If the purpose of these missions is not peer-reviewed, documented scientific advancement then why are we investing ~ 500 million dollars/launch for pretty pictures of Earth from LEO?
We don't want to waste our time constructing experiments to test crack-pot theories, but if a prevailing theory can be justified or refuted by an experiment then that is a perfectly valid way to make scientific progress.
Consider the Michelson-Morley experiment. Aether is a good theory or it's not. The experiment was done, the theory went down the tubes. A fundamental scientific breakthrough was the result. A null result can be a very powerful scientific argument.
"I wouldn't be surprised if the main structure could be plastic, with a thin(ner) outer shell of some metal"
Wrong order dude. The light weight shielding has to be on the outside or you miss the point. Sure there will be some of the very energetic particles that penetrate the outer hull but the vast majority of the particles will produce the secondaries in the outer hull, therefore the low-Z material must be on the outside (to get the desired effect).
":There's one thing being developed at the space station that is terribly important for manned space flight: a radiation shield"
So they are developing a "radiation shield" on the space station? I'm looking forward to reading the papers on this topic.
"When we went to the Moon, how big a ship we could take and how long we could stay were limited by exposure to the van allen belts."
And what L shell is the moon at? Like 57 or something? Radiation is certainly an issue at L shells of like 1.5-4 but beyond that it's a non issue.
"If we wanted to take a hundred people to the Moon we had to do it in 40+ trips cause any ship that could carry 100 people would expose them to radiation for too long."
Hum...your math lost me there.
"Having a station at the L1 libration point (where the gravity of the Moon and Earth meet)"
No, the L1 point is where the forces between the Earth and the Sun are balanced. We have a number of spacecraft there... ACE, SOHO, WIND, etc...
"would allow us to refuel, change ships and do science."
While your there would you please replace my thermal blankets and one of my SSDs, it's become pretty noisy. I'll gladly pay perdium.
"But you can forget about it if we have to make a radiation shield out of physical materials"
So what do you propose we make our shields out of? I guess I'm kind of behind the times on the un-physical-shielding-materials.
"So yeah, until we get that breakthrough"
in what?
"(and some breakthroughs in propulsion would be good too)"
agreed
"we won't have anywhere to go."
Does anything in your discussion have to do with where we go? --
Title:
Spacesuit glove manufacturing enhancements through the use of advanced technologies Authors:
Cadogan, David; Bradley, David; Kosmo, Joseph
Abstract The sucess of astronauts performing extravehicular activity (EVA) on orbit is highly dependent upon the performance of their spacesuit gloves.A study has recently been conducted to advance the development and manufacture of spacesuit gloves. The process replaces the manual techniques of spacesuit glove manufacture by utilizing emerging technologies such as laser scanning, Computer Aided Design (CAD), computer generated two-dimensional patterns from three-dimensionl surfaces, rapid prototyping technology, and laser cutting of materials, to manufacture the new gloves. Results of the program indicate that the baseline process will not increase the cost of the gloves as compared to the existing styles, and in production, may reduce the cost of the gloves. perhaps the most important outcome of the Laserscan process is that greater accuracy and design control can be realized. Greater accuracy was achieved in the baseline anthropometric measurement and CAD data measurement which subsequently improved the design feature. This effectively enhances glove performance through better fit and comfort.
I've done extensive experiments on the whole masturbation-tilted-penis issue and have concluded that a significant investment is required to fully understand this issue. I propose that a series of experiments are conducted (in low G) to fully understand the quantum-mechanical effects of low-G masturbation. Now it's just the scotch talking... I'm going to bed.

Without the investment in NASA we would not have cell phones, GPS, or weather monitoring.
"NASA is a government work program "
Like anything that the government does could not be put in this category.
As a "work program" the investment in NASA has been one of our best successes. The number of private businesses it has spawned cannot be counted.
