I favor NASA...or anyone...Research is a good thing! I favor NASA...or anyone else doing it.<br /><br />However, once NASA withdraws from human spaceflight, I fear that funds will never be returned for that purpose.<br /><br />This is my key objection to the Obama space plan; I foresee lots of research, and no money ever to build anything.<br /><br />Furthermore, isn't the HLV yet another spacecraft built without a purpose? Isn't it just like the shuttle in that way?<br /><br />I love the private space companies, but——with the possible exception of a Dragon/Falcon human loop around the moon——I don't see them getting us beyond earth orbit anytime soon.<br /><br />As you know, the last scheduled Apollo flights were canceled by budget cuts. NASA was hoping to do some amazing things: land men on the far side; send them on lunar surface missions with (essentially) flying backpacks, etc.<br /><br />von Braun——the true NASA visionary——hated what was happening with the shuttle. His opposition was one of the reasons he quit.<br /><br />NASA, desperate to continue manned spaceflight, grabbed the shuttle and tried to please everybody. They said "yes"; but maybe they should have said "no". The could have said...come back when you're serious about manned spaceflight, and bring the needed money.<br /><br />But, we were stuck with brilliant engineers, etc, operating an unnecessarily flawed vehicle. And the International Space Station was also, I believe, a mistake. A smaller one with just what we need (perhaps an enhanced Skylab?) would have done the job.<br /><br />I really want to love the new space plan. But I'm afraid I won't live to see another American astronaut fly a U.S. built spacecraft beyond earth orbit. I very much hope my pessimism is misplaced.<br /><br />BTW, I love your blog and put it on my blogroll at http://www.thespacebuff.comRay Katzhttp://www.thespacebuff.comnoreply@blogger.comtag:blogger.com,1999:blog-335935790442647770.post-31459627121502920262010-06-03T02:50:06.719-07:002010-06-03T02:50:06.719-07:00Ray,

Nixon made them choose one, but that was well after they had sacrificed the Saturn 5 Assembly line.<br /><br />Now, we need new technology and NASA is only going to get so much money. NASA can not afford to do missions at the same time it experiments with the technologies needed to explore beyond Low earth orbit.<br /><br /> Times of trauma are not good times to come up with long term plans. Also one of NASA's prime causes for failure has been pre-mature choice.<br /><br />If we continue using the Shuttle derived architecture which was designed by committee the Chinese will pass us by. If we are a little patient and spend a few years developing new technologies we will leave them in the dust.Karen Cramer Sheahttps://www.blogger.com/profile/02401187287904799543noreply@blogger.comtag:blogger.com,1999:blog-335935790442647770.post-23366647081357917712010-06-02T16:02:28.353-07:002010-06-02T16:02:28.353-07:00This is a strange alternate history. NASA didn'...This is a strange alternate history. NASA didn't want a shuttle. It wanted to expand our exploration of the moon and go on to Mars.<br /><br />But Nixon cut the budget and demanded something re-usable...with military benefits.<br /><br />Everybody got a piece of the specs for the shuttle. So, we got a horse designed not by NASA, but by a committee. We got a camel.<br /><br />The shuttle is a very dangerous vehicle, and only capable of earth orbit. Considering what they've been forced to work with, going more than a quarter of a century with only two fatal accidents isn't incompetence; it's brilliance. Imagine how many failed, fatal moon flights we would have had...no matter how competent management...if we continued that program for a quarter century.<br /><br />One inevitable part of space flight: it's risky. So, let's take risks for pushing the envelope, not endlessly circling the planet.<br /><br />Meanwhile, the new "plan" is to study things, and build nothing. It's great to encourage private companies to do earth orbital missions. But they're nowhere near getting us beyond earth orbit.<br /><br />And since NASA is prohibited from building such vehicles, we're going to spend another umpteen years mostly 120 miles above the planet.<br /><br />We'll watch Chinese astronauts go to the moon and beyond.

I was expressing how sad it was in the light of his past accomplishments. <br /><br />I used the word hero in both senses of the word. One the term describing the classic tragic character, the other as some one to be admired for his accomplishments.<br /><br />When Dr. Nozette got Clementine funded and flown we hadn't been to the Moon in decades and NASA had no intention of ever sending even a probe back. The Moon is the key to space development, with out it there will be no long term space development. Without Dr. Nozette there would have been no Clementine. Without Clementine there would have been no Lunar Prospector or knowledge of water on the Moon or a new Vision for Space Exploration. Without Dr. Nozette there would have been no movement towards lunar development. Dr. Nozette was my hero, even though I knew he was a deeply flawed man.I just didn't realize how deeply flawed.<br /><br />On the subject of explaining terms. I am sorry that I did not realize that I had the benefit of a superior education and Keith did not. I studied Tragedies multiple times in high school and as an undergraduate and assumed that others had too. <br /><br />I would think if Keith is going to the trouble to pull a deleted article up from the Google cache and post it in its entirety, violating copyright, he would go to the trouble of understanding it. Even if that requires a Google search or two on terms. He obviously knows how to use google.Karen Cramer Sheahttps://www.blogger.com/profile/02401187287904799543noreply@blogger.comtag:blogger.com,1999:blog-335935790442647770.post-30051137048056953512009-10-28T21:20:13.473-07:002009-10-28T21:20:13.473-07:00This comment has been removed by the author.Karen Cramer Sheahttps://www.blogger.com/profile/02401187287904799543noreply@blogger.comtag:blogger.com,1999:blog-335935790442647770.post-34537223777116147792009-10-28T14:57:20.132-07:002009-10-28T14:57:20.132-07:00Keith isn't concerned by you.

He's concerned that you may be an apologist for Nozette.<br /><br />I see a good analogy between Stewart Nozette, Bill Clinton, Eliot Spitzer, Mark Sanford, and the NWA pilots (overflying MSP) -- how could somebody who had so much going for them put it all at risk for something so stupid? In that sense this is classic tragedy, but the word hero (as known today) sticks in the craw. Its usage in the study of Greek lit is not sufficiently well known, and therefore any use of the term requires a paragraph or two of education to avoid misunderstandings. <br /><br />That was your mistake.

Reusable vehicles and a large traffic model will get that down, but even a milion tons per year is unlikely to get it below $500/kg. At that cost a robot run moon base might be built, but the cost is over a trillion dollars and it takes decades.<br /><br />I have worked out a proforma analysis of a transport system using chemical rockets for the first stage and high exhaust velocity laser propulsion for the second stage. After several years of buildup, the cost goes under $100/kg and the cost of power falls to where it displaces fossil fuels by simply underpricing them. The peak investment for this first pass attempt came in a bit under $60 billion and it rapidly pays back the entire capital.<br /><br />It's still a big number and it's difficult for me to explain to people. I think people really need to appreciate the rocket equation, i.e., rocket science, to understand why this is a 5 to 1 improvement. That's unrealistic so I am looking for a way to get the idea over to people who will never get the concept of exponential.<br /><br />Google oil drum henson to see my attempt to explain it. Ideas on how to make it understandable to non rocket scientists would be highly appreciated.<br /><br />Of course if we start building power satellites with all the parts hauled up from the earth using human labor, space habitats and ET materials should just develop naturally. Especially since the best power sat design uses so much nickel.<br /><br />Keith HensonKeith Hensonhttps://www.blogger.com/profile/09561139106291475285noreply@blogger.comtag:blogger.com,1999:blog-335935790442647770.post-90276704538237441222009-07-22T11:11:45.516-07:002009-07-22T11:11:45.516-07:00Hi Karen,
