"Visibly shaken"? I don't see that.
Today we have with us a group of students, among America's best. To you we say we have only completed a beginning. We leave you much that is undone. There are great ideas undiscovered, breakthroughs available to those who can remove one of the truth's protective layers. There are many places to go beyond belief. Those challenges are yours--in many fields, not the least of which is space, because there lies human destiny.

I think this statement deserves to be 'pounced' upon. It's highly unusual and one I've never heard anyone else say.
What do you think Armstrong meant when he said this?
"There are great ideas undiscovered. Breakthroughs available to those who can remove one of truth's protective layers."
What do you think he meant by truth's protective layers? What truth, and what protective layers?

A good example is plate tectonics.
The probe plans to test technology in preparation for an unmanned moon landing in 2012, with a possible manned lunar mission to follow in 2017.
Obama's space plan also calls for astronauts to visit an asteroid by 2025 and then aim for a manned Mars mission in the 2030s. A heavy-lift rocket for those missions was slated to begin development in 2015.
Under the spending bill approved Wednesday, NASA would be directed to begin work on that heavy-lift rocket in 2011 – four years earlier than the White House proposal.
Congressman Pete Olson (R-Texas) said such a rocket is vital for NASA to fulfill its original purpose.
"Our future in space is not in low-Earth orbit. We have to go beyond," Olson said during the vote's debate. "A heavy-lift vehicle will enable us to achieve the true mission of the agency ... to explore."

And maybe NASA don't have the Moon in their sights as a primary target anymore...
DALLAS—Speaking from his home in Dallas, former president George W. Bush told reporters Tuesday that when he's not busy giving lectures or writing his memoirs, he spends most of his spare time working on the manned mission to Mars he proposed in January 2004.
"This is genuinely important to me," said Bush, looking over sketches of potential rocket systems he had drawn up while waiting for his oil to be changed at a service station earlier this week. "I wasn't kidding when I announced a plan to get us to Mars, by God, and I intend to finish what I started. That's why I try to carve out a little time before lunch and after dinner to work on this important interplanetary initiative."
George Mueller left private industry to become NASA's Associate Administrator for Manned Space Flight in September 1963. He immediately asked John Disher and Adelbert Tischler, two veteran NASA engineers not directly involved in Apollo, for an independent assessment of the moon program. On September 28, they told Mueller that it could not achieve President Kennedy's goal of a man on the moon by 1970. They estimated that NASA might carry out its first manned moon landing in late 1971.
Many believed that NASA should have backup plans in case the Saturn V or Apollo spacecraft suffered development problems. Eighteen months after Mueller's announcement, E. Harris and J. Brom, engineers with The RAND Corporation think tank, proposed one such backup plan. Their brief report, originally classified "Secret," looked at how NASA might accomplish a manned moon landing by 1970 if the Saturn V could not be certified in time as being safe for astronauts.
RAND Corporation (Research ANd Development) is a nonprofit global policy think tank first formed to offer research and analysis to the United States armed forces by Douglas Aircraft Company. It is currently financed by the U.S. government, a private endowment, corporations including the healthcare industry, universities and private individuals
RAND was set up in 1946 by the United States Army Air Forces as Project RAND, under contract to the Douglas Aircraft Company, and in May 1946 they released the Preliminary Design of an Experimental World-Circling Spaceship. In May 1948, Project RAND was separated from Douglas and became an independent non-profit organization. Initial capital for the split came from the Ford Foundation.
The achievements of RAND stem from its development of systems analysis. Important contributions are claimed in space systems and the United States' space program, in computing and in artificial intelligence. RAND researchers developed many of the principles that were used to build the Internet. RAND also contributed to the development and use of wargaming.
Since the 1950s, the RAND has been instrumental in defining US military strategy. Their most visible contribution is the doctrine of nuclear deterrence by Mutually Assured Destruction (MAD), developed under the guidance of then defence secretary Robert McNamara and based upon their work with game theory. Chief strategist Herman Kahn also posited the idea of a "winnable" nuclear exchange in his 1960 book On Thermonuclear War. This led to Kahn being one of the models for the titular character of the film Dr. Strangelove
The character is an amalgamation of RAND Corporation strategist Herman Kahn, mathematician and Manhattan Project principal John von Neumann, German rocket scientist Wernher von Braun and Edward Teller, the "father of the hydrogen bomb."
Harris and Brom's backup plan would see the Apollo Saturn V lift off without astronauts on board. It would expend its S-IC first stage and S-II second stage in turn, then its S-IVB third stage would place unmanned Apollo Command and Service Module (CSM) and Lunar Module (LM) spacecraft into parking orbit about the Earth.
The astronauts would reach Earth orbit separately in a ferry CSM on top of a two-stage Saturn IB rocket (bottom image above). The ferry CSM would carry a special drogue docking unit for docking with the unmanned lunar mission CSM's probe docking unit. The only new system required for the backup plan, the special drogue would need about one year and "perhaps several million dollars" to develop.
The astronauts would dock with and transfer to the lunar mission CSM in Earth orbit, then would cast off the ferry CSM. The remainder of the mission would occur as in NASA's Apollo plan. The astronauts would restart the S-IVB stage to leave Earth orbit for the moon.
NASA officials did not take up the Harris and Brom proposal, though for a time in 1968 they might have wished that they had. The first unmanned Saturn V test flight, Apollo 4, lifted off on November 9, 1967. In keeping with Mueller's 1963 directive, it included complete S-IC, S-II, and S-IVB stages, plus a CSM with LES (top image above). Because LM development had hit snags, a dummy LM rode inside its SLA. The eight-hour Earth-orbital mission was an unqualified success.
Apollo 6 was, however, another story. On April 4, 1968, two minutes into its unmanned flight, the second Saturn V to fly began to shake back and forth along its long axis. Dubbed "pogo" by engineers, the shaking knocked pieces off the SLA and damaged one of the S-II's five engines. Following S-II ignition, the engine underperformed and shut down prematurely, then a control logic flaw caused a healthy engine to shut down. The remaining three S-II engines burned for a minute longer than planned to make up for the lost engines. The S-IVB's single engine then burned for 30 seconds longer than planned to reach a lopsided Earth orbit. Two orbits later, it failed to restart.
The pogo might have injured astronauts; the S-IVB failure would certainly have scrubbed their flight to the moon. Post-flight analysis showed, however, that the pogo and engine failures had simple fixes. After intense internal debate, NASA decided in October 1968 that the third Saturn V should launch Apollo 8 astronauts Frank Borman, James Lovell, and William Anders. The giant rocket performed flawlessly, placing the Apollo 8 CSM on course for lunar orbit on December 21, 1968.

To summarize, Apollo could have launched to the moon without anybody onboard.
Exactly what were the astronauts used for?
First, I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. We propose to accelerate the development of the appropriate lunar space craft. We propose to develop alternate liquid and solid fuel boosters, much larger than any now being developed, until certain which is superior.
