Neil Armstrong, on Space Exploration


Neil Armstrong: modest man, large footprint in time and space
[...] After commanding the Apollo 11 mission, Armstrong took a desk job at the National Aeronautics and Space Administration, then taught engineering at the University of Cincinnati, served on several corporate boards, and worked out of his farm in southwest Ohio. He said he regretted not spending the time he wanted to with his family.

"I am, and ever will be, a white socks, pocket protector, nerdy engineer," he said in a rare public appearance in February 2000, cited by The Associated Press. "And I take a substantial amount of pride in the accomplishments of my profession."

He also regretted that the US space program did not make more progress than it did. "I fully expected that by the end of the century we would have achieved substantially more than we did," he told "60 Minutes." The end of the cold war also marked the end of the drive for space dominance, he said. "When we lost the competition, we lost the public will to continue."

In 2010, he came out of retirement to make a case before the US Congress to restore funding and a vision for the US space program and a workforce he described as "confused and disconsolate" by the termination of the 30-year space shuttle program, layoffs of thousands of aerospace workers, and the absence of a new US space strategy.

Public policy must be guided by the recognition that we live in a technologically driven world, he told a House panel. "Our choices are to lead, try to keep up, or get out of the way" he said. "A lead once lost is very difficult to regain."

"Neil Armstrong understood that we should reach beyond the stars," said Sen. Bill Nelson (D) of Florida, a former NASA shuttle astronaut, in a statement. "His 'one giant leap for mankind' was taken by a giant of a man." [...]

R.I.P. Neil Armstrong


From Wikipedia: Neil Armstrong
Neil Alden Armstrong (August 5, 1930 – August 25, 2012) was an American astronaut, test pilot, aerospace engineer, university professor and United States Naval Aviator. He was the first person to walk on the Moon. Before becoming an astronaut, Armstrong was a United States Navy officer and had served in the Korean War. After the war, he served as a test pilot at the National Advisory Committee for Aeronautics High-Speed Flight Station, now known as the Dryden Flight Research Center, where he logged over 900 flights. He graduated from Purdue University and the University of Southern California.

A participant in the U.S. Air Force's Man In Space Soonest and X-20 Dyna-Soar human spaceflight programs, Armstrong joined the NASA Astronaut Corps in 1962. His first spaceflight was the NASA Gemini 8 mission in 1966, for which he was the command pilot, becoming one of the first U.S. civilians in space.[1] On this mission, he performed the first manned docking of two spacecraft with pilot David Scott.

Armstrong's second and last spaceflight was as mission commander of the Apollo 11 moon landing in July 1969. On this mission, Armstrong and Buzz Aldrin descended to the lunar surface and spent 2½ hours exploring, while Michael Collins remained in orbit in the Command Module. Armstrong was awarded the Presidential Medal of Freedom by President Richard Nixon along with Collins and Aldrin, the Congressional Space Medal of Honor by President Jimmy Carter in 1978, and the Congressional Gold Medal in 2009.

On August 25, 2012, Armstrong died in Cincinnati, Ohio[2], at the age of 82 due to complications from blocked coronary arteries. [...]

NASA goes Back to the Future

I remember when I was a teenager, when the first American Space Shuttle was unveiled. It was kinda fat and chunky looking, but it was still a real spaceship. It was a beginning. I was sure that within my lifetime, we would eventually have spaceships like the elegant Orion Space Clipper that was featured in the movie "2001: A Space Odyssey":




Wow. Well, here it is, 2008. NASA is going to retire our clunky space shuttle by 2010, and introduce a newer, next-generation spacecraft to replace it. Coincidentally, it's going to be called "Orion", and will be used to shuttle astronauts to and from the International space station, AND to the moon and back. That's right, we're going back to the moon, and it's scheduled to happen no later than 2020. Then, on to Mars...

Fabulous! Soon we will get to see this new Orion spaceship, which is being built right now. But we don't have to wait until it's finished to see it, NASA has already made the plans public! So here it is, the NEW Orion space shuttle:




But, but... that's an APOLLO space CAPSULE, isn't it? Well, it's a similar design. It's actually 2 and 1/2 times larger than the Apollo version, it can hold up to six astronauts for shuttle missions, and four astronauts for Lunar missions. Here is a picture of the Orion with a lunar module attached:




Looks familiar, doesn't it? I had trouble deciding wether to call this post "Back to the Future" or "Everything old is new again".

So what happened to our beautiful Orion Space Clipper? Why are we going back to designs from 40 years ago? There's two major reasons I can think of: cost, and safety.

These old designs are tried and true. We know they work. Update them with new technology, and they work really well. I also suspect that with new technology, they are cheaper to build than anything else. Here is a picture of the new Orion capsule with it's solar cells and antennae dish deployed:






We are simply building on old technology, using what we know works, and making it better. Click here for more pics of the Orion spacecraft.

The space shuttle aircraft we've used for the past three decades are made from a more bold and ambitious design, but are also more complex and fraught with dangers. Consider the Challenger accident, the shuttle that exploded after launching; the Columbia burning up while returning to earth.

The Challenger crew could not be saved. However, with the new Orion design, the crew can be saved if the rocket explodes on the launch pad, or in the air. The capsule has a rescue rocket on top, to lift it way from danger.

The Columbia crew died when their damaged heat shield failed on reentry. The Orion capsule's heat shield is protected from damage during liftoff, and is a round shape that is easier to build and maintain.

Every time astronauts die, people call for an end to the space program. By going back to old designs and improving them, we are saving both money and lives. It's hard to argue with that. So I may not see this in my lifetime:





But hopefully I will see this:





If we have to sacrifice elegant design for the safety of our astronauts and the efficiency of our space program budget, then so be it. As we learn more we can get fancier; but we need to grow into it at a natural pace. Slow but steady progress with it's attendant successes will get us where we want to go.

The new back-to-the-moon mission is called the Constellation Program. The link goes to NASA's website, where you can find out lots more details about the mission and photos of the various spacecraft being developed. I had lots of fun looking around there. If you are a space fan, be sure and check it out.






It's back to the future... are you ready? I am, let's go!





First, the moon once again. Then look out Mars, here we come...
