Naked Science: Living on the Moon



The National Geographic Channel is showing a not-to-be-missed program on returning to the moon, this time to stay.

Naked Science: Living on the Moon airs on Sunday, July 19 at 9:00 p.m. Pacific and Eastern time, the day before the 40th anniversary of the first manned moon landing by Apollo 11.

I got a review copy of the show, which is a well balanced treatment of what's required for going back to the moon, setting up a permanent base, and eventually building a self-sustaining economy with a frontier settlement. As I expected, NASA gets top billing with its planned Constellation mission for returning astronauts to the moon some time in the next decade. But the show's producers don't treat NASA as the end-all-be-all for manned space flight, and herein lies its main strength.

Instead, the show acknowledges the past contributions of NASA, treats its current plans, and also points out that other nations such as India and China are in the running too, as well as private companies, setting the stage for an exciting next couple of decades in space.

Peter Diamandis, founder of the X PRIZE that helped launch the private space race gets air time, as does Rick Tumlinson, co-founder of the Space Frontier Foundation.

"Today there are twelve hundred billionaires on this planet," says Diamandis. "And what it used to take a large government agency to do, a small group of dedicated individuals with the right computational capabilities can now do."

With that, the show makes the case for not just going back to the moon, but that the profit motive makes it inevitable. Exceptional animations round out an inspiring program that should be required viewing for anyone who questions the value of continuing to reach beyond planet Earth.

SpaceX first operational satellite launch


Last night Space Exploration Technologies (SpaceX) launched its first operational satellite from its pad in Marshall Islands. This is the first time that a privately funded liquid fuel rocket has achieved this milestone.

This was the fifth launch of the Falcon 1 rocket and the second time it succeeded in reaching orbit (the last payload was of a dummy satellite).

It's another vindication of SpaceX founder and CEO Elon Musk's plan to revolutionize space access with cheaper, more routine access to space, and it couldn't come at a better time--as the independent Human Space Flight Review Committee prepares to advise the White House on the future of America's national space program.

SpaceX's next launch will be a test flight of its Falcon 9 rocket. Powered by 9 Merlin engines, one of which drives the Falcon 1, the Falcon 9 is designed for nothing less than human space flight, with a potential crew of seven astronauts.

The company is already working under a $1.6 billion contract to deliver cargo to the International Space Station after the space shuttle retires next year (Orbital Sciences Corporation has a similar contract).

SpaceX hopes to go beyond mere cargo flights to the station, however. As I saw on a recent visit to SpaceX HQ in Hawthorne, CA, all of the company's Dragon crew capsules--even those intended for cargo--will have windows....

Len Kleinrock describes the birth of the Internet

Leonard Kleinrock, who published the first paper on packet switching in 1962, and who led the ARPA-funded team at UCLA that made the first connection on the Internet, described the scene to me on the phone to me a few minutes ago.

Sitting at a computer terminal at UCLA on October 29, 1969, one of Kleinrock's team members typed two letters that were received via the infant Internet by a computer up the California coast at the Stanford Research Institute. The connection worked beautifully for those two letters--before the receiving computer crashed.

The UCLA team had been trying to send "LOG" as in "LOGIN" (the "IN" would have been sent by the other computer). "We didn't have a tape recorder, or reporters or anybody else--just myself and one of my programmers there," Kleinrock told me. "We didn't understand PR or media--press--the way that Alexander Graham Bell did or Samuel Morse or Armstrong. Those guys were smart. They had it all prepared. But it turns out that the message is probably the shortest, most prophetic message you can have created by accident. The fact is those first two letters spelled a beautiful word: 'Lo,' as in 'Lo and behold!'"

Kleinrock tells the story, complete with whiteboard diagrams, in this video from UCLA:
