They upgraded the shuttle electronics and made some other tweaks but the airframe looks pretty much the same as the orginal, and now it's obsolete. Not only did our space program stop progressing, it actually regressed, as we don't have the ability to put a man on the moon today, according to the space center tour guide speech given when I visited the space center. And yes I believe it.

SDI just isn't in the news anymore like most of our space programs.
Question / Statement: We went from a hang glider to landing on the moon in 70 years. Do you guys really think we suddenly stopped progressing in our space program? We currently "use" the same rocket technology in "Public" that we did 40 years ago.... The space shuttle hasn't really changed much since the early 80's.... Really?
was designed for use against tactical ballistic missiles (TBMs).

But are you saying you think we have the ability to put a man on the moon today like we did in the 1960s?
Or would we have to re-develop the means to do it?

I looked it up in Wiki, the US spent over $100 billion on it!:

SDI was mere propaganda designed to let the Russians think the Americans were going to do it. They never did, and the 747 born Lasers are far far cheaper, relatively, to design build and fly than space platforms.
I didn't realize the Missile Defense Agency was the remnants of the SDI organization, but it makes sense.
the U.S. has certainly invested well over $100 billion on "SDI" and follow-on programs
Under the administration of President Bill Clinton in 1993, its name was changed to the Ballistic Missile Defense Organization (BMDO) and its emphasis was shifted from national missile defense to theater missile defense; and its scope from global to more regional coverage. It was never truly developed or deployed, though certain aspects of SDI research and technologies paved the way for some anti-ballistic missile systems of today. BMDO was renamed to the Missile Defense Agency in 2002.
The articles I've read say the blueprints are useless and there would need to be redevelopment, probably starting from scratch. And unlike the decade it took at Kennedy's coaxing, I doubt the space program will ever be funded that well again unless aliens attack or something, so it will take longer than a decade to put a man on the moon if we decide to start working on it today:

We still have the blueprints, calculations, etc. The hardware is too old to be reliable, so it would have to be rebuilt, and while doing so, no doubt you'd put in updated electronics, etc. There wouldn't be any need for "redevelopment" though...and we do have the ability.
They mention another large rocket NASA is developing, the magnum, but it still doesn't have the capacity of the Saturn V, that thing could launch 100 tons of payload, what a monster!
Geoffrey Hughes from the Rotary Rocket Company supported Shawcross's view.
"There is no point in even contemplating trying to rebuild the Saturn 5," he said. "Having a complete set of Saturn 5 blueprints would do us no good whatsoever. True, we would still be able to bend the big pieces of metal fairly easily. But they are not the problem.
"The real problem is the hundreds of thousands of other parts, some as apparently insignificant as a bolt or a washer, that are simply not manufactured any more. Everything would have to be redone. So a simple rebuild would be impossible. The only real answer would be to start from scratch and build anew using modern parts and processes.
Yes, that's a good question, and you answered your own question about "why" with the exploration base, so until we design a manned mission to Mars, I'm not sure what it will look like and if it might involve a moon base for launch...maybe not. There's also the He3 on the moon to be mined, but we have no reactors that can use it yet so that's sort of pie-in-the-sky right now.
The better question though, is would and should we? Unless we're establishing a base there as a platform for further exploration, going there just to go there is fiscally irresponsible. We don't NEED new tech to go to the moon, but we would USE it to do so...just as you don't NEED a camera on your phone, but it won't keep you from using it when you want to....

SDI never existed other than a concept.
The UK has just sent up a new communications satellite that's completed their Skynet, the highly-advanced network that's going to give them the ability to allow robotic military units at long range. You know, like in the apocalyptic vision of the future from the Terminator movies. The network's name in those movies? Skynet. Have you learned nothing, England?! The system allows for communication both in the voice and data variety between basically any unit of the British Armed Forces, including computers talking to computers, probably about how best to murder their makers. For example, a base computer in cheery old London can communicate with the "Reaper," a robotic spy drone in Afghanistan, retrieving data and telling it where to go, and transmitting live video over the connection from the UAV. The sat also has solar sails which extend its life to 15 years, a special anti-jamming antenna is set on the receive side, while 4 steerable antennas can be aimed in a single spot to concentrate broadcasting ability. Even worse is the fact that the whole thing is privately owned, with the British Armed Forces only promised a portion of the bandwidth rather than having control over the whole thing.
