Subject: To The Moon, Shouldn't we?
Good day to you on the lunar-update list and those I included as
well. You folks are great! Several of you sent me the link to the
Science@NASA article on the Deep Space Network big dishes. For you
that haven't already seen the article, here is the link.

Dr.Tony Phillips is the editor of the web site and it is always a
pleasure to go there. You can even listen to the article. When you
look at the site notice that we are continuing to go far away and
need to listen to what is being said.
You will understand why trying to find a time slot to listen to
Pioneer 10 is really hard to do. Everyone is in the room, wanting to
be heard. Just tap your glass to get someone's attention. And a
toast to PN10, "Hear, Hear, May It Be Heard"
From down under, Robert Clements sent me two articles from India. One
about Eugene Cernan's book "The Last Man On The Moon" and one about
India wanting to go to the Moon.
Robert has a mission in mind also, but this would be to an asteroid.
I am going to copy them. Hope you won't think them too long.
When you are done with those and want to read more about what we were
doing on the moon, take a look again at the Apollo Lunar Surface
--- The Apollo Lunar Surface Journal is a record of the lunar surface operations conducted by the six pairs of astronauts who landed on the Moon from 1969 through 1972. The Journal is intended as a resource for anyone wanting to know what happened during the missions and why. It includes a corrected transcript of all recorded conversations between the lunar surface crews and Houston. The Journal also contains extensive, interwoven commentary by the Editor and by ten of the twelve moonwalking astronauts. ---
We have been there, done that. Now let's do it again. (in more detail, over more of the surface, for a longer time)
Just think of all the jobs that would be created trying to develop those new opportunities (solve problems - right mind set required).
Larry Kellogg, for you folks looking up ===========================================================================
What he describes is difficult to imagine, what he feels tough to comprehend, what he has seen out of this world. Literally. Twenty-eight years and five months have passed since the historic American triumph on December 11, 1972. But Eugene Cernan, 67, commander of Apollo 17, the last spacecraft to land on the moon, has not forgotten the exhilaration he experienced then. "It's a gulp at first. It's almost like your stomach floats up to your head instantaneously. All the artificial gravity produced by the rocket suddenly stops and you begin to float. Then suddenly, you can bounce and jump around which is impossible, just impossible, on earth." The fact that 700,000 people from as far away as England and Australia assembled at the launch pad on December 6, 1972 did not help ease the pressure on Cernan and his fellow astronauts, Jack Schmitt and Ron Evans. To top that, a computer failed and the take-off was put forward by more than two hours. Finally at 12:33 am, Florida time, Apollo 17, which witnessed the only last-minute glitch ever in the history of the Apollo series, left for the moon. It was a mission that had been accomplished before. But still it went on to become a landmark in the history of mankind. "I wanted it to be the best, most complete and obviously the safest mission. We weren't the first, but I wanted it to be the best," recalls Cernan. Cernan's first space voyage was on Gemini 9, on June 3, 1966, when he made a record 130-minute space walk. His second flight was aboard Apollo 10 in May 1969. And his last, and most illustrious, was as the commander of Apollo 17 in 1972, where he spent over 22 hours walking on the moon, exploring 21 miles of its surface. "People who had been to the moon do talk about it. But nothing prepares you for being there and looking through a quarter of million miles back at earth. That is a real experience that you just cannot simulate. Nobody can tell you about it." And after three days, 12 hours, six minutes and 31 seconds into Apollo 17's flight, the moon appeared to the astronauts some 10,000 miles away. "Boy, is it big! We're coming right down on top of it!" was what Cernan shouted when he saw the 'magnificent' body staring at him. Apollo 17 was carrying the eighth and last crew to the moon, almost four years after Apollo 8 first began to weave man's first loops around the moon and three and a half years after the first men in Apollo 11 touched down on the moon. Even today, the only description Cernan can think of for the moon is 'magnificent desolation'. "It's all grey, but those mountains rise above the flat valleys and they are truly magnificent. Even when you are in orbit around the moon, the horizon which is more curved than even the earth, shows the mountain peaks," he says almost as if envisioning the moon in front of his eyes. This extract from The Last Man on the Moon, which Cernan co-authored with journalist Don Davis, captures his emotions effectively: "Not the song of a bird, the bark of a dog, not a whisper of wind or any familiar sound from my entire life. I was totally enveloped by such a thorough and complete stillness that I have difficulty comprehending it even today. The only sound inside my helmet was my labored breath and even that slight disturbance seemed so terribly intrusive that for a brief moment, I stopped breathing, too. Then there was nothing at all." Cernan says the change from gravity on earth to zero gravity in the spacecraft to 1/6th gravity on the moon is not as rapid and abrupt as people think. In fact, one tends to adapt very quickly to the changing atmospheric conditions. He recalls how they assembled the lunar rover, picked up the 209 kg machine and actually turned it around. "You can do things in 1/6th gravity that you can't do in earth gravity. You're right. When you go to the moon and experience 1/6th gravity, you no longer take earth gravity for granted." The one sight that in an inexplicable way kept him sane and going was the earth leisurely rotating on its axis, nights turning into days and days into nights, as the sun illuminated the planet with its blinding light. He had set his watch to Houston time, so he would know exactly what his daughter Tracy was doing back on Planet Earth. Cernan, though he graduated in electrical engineering from the Purdue University and did his masters in aeronautical engineering from the U S Naval Postgraduate School, doesn't speak the 'tech-lingo'. "I cannot believe that anyone who goes to the moon doesn't come back a little more philosophical. I cannot express myself in pluses and minuses or in technical terms. How does one define fear, apprehension or love in technical terms? "Technology is supposed to get me on the moon and off the moon. But while I'm there, it had no role in the feelings I felt when I looked at earth. There was history there. I was at a place that you may picture only through the words of poets, paintings or perhaps in the minds of philosophers," he says. Although there are many things that Cernan wished he had done while he was up there, he is thrilled and thankful that he wrote his daughter Tracy's initials in the sand. "You can't remember to say and do them all, but you have to accept what you have done," he says very practically. Another feather in Cernan's cap is that he was the senior negotiator for the United States during its discussion with the Soviets on Apollo-Soyuz, the 1975 joint American-Soviet space mission. So how was his experience on this mission with Russia, especially during those days of the Cold War? "Challenging" is how Cernan describes it. "It was very easy to work with their cosmonauts because we all had something in common, but it was very difficult penetrating the Soviet bureaucracy," he says. But he admits a lot of good came from the trip because it enabled them to interact with people who they were treating as enemies for a long time. "We found ourselves on a different plane than the politicians," he says. At times Cernan gets a bit uncomfortable with all the attention that comes his way. But then, he is among the 12 people in the world to have walked on another planet. Cernan is concerned that it's been almost 30 years since the last expedition to the moon. He attributes America's success in this regard completely to President John F Kennedy. "This couldn't have happened without him," he acknowledges. "But since we no longer have a John Kennedy amongst us, we have to take it onto ourselves". Cernan looks at himself as a normal human being who had his chance to do something unique. "I didn't want to come back with half a loaf of bread. I wanted to come back and have people to say that it was the best," he says.
Sarabhai space centre set to take giant leap with mission to moon Janayala Sreenivas Ahmedabad, May 31: AT THE Vikram Sarabhai Space Applications Centre (SAC), Ahmedabad, the tranquility is deceptive. Inside its research stations and laboratories, scientists' pulses are racing with excitement at what they are working on: A mission to the moon. ''The mission is very much a reality,'' said Dr K. Kasturirangan, chairman, Indian Space Research Organisation (ISRO) who was here to oversee. Very soon, ISRO, which runs the centre, will prepare a blue print for a satellite that will either orbit the moon 100 km from its surface or even fire a probe that land on its surface. And a National Committee on the Moon, led by SAC director Dr George Joseph, will submit to the Department of Space a report ''on whether we should simply fly by the moon, orbit close around it, or send in a lander or a probe vehicle''. The committee of crack scientists drawn from ISRO and the Department of Space and led by Joseph is first studying what immediate technological development will be required to fly by the moon or put a probe on it. The committee is also researching some futuristic prospects - commercial exploitation of the moon, the moon as a strategic defence point and the moon as a launch point for exploring space. ''We are working on what our present capabilities are and what advancement we need to make to accomplish mission moon,'' Joseph said. ''Though we are not putting a man on the moon, not yet, we certainly can put a probe or a lander.'' ISRO has already studied some possible landing sites, besides tracking polar orbits for satellites. But what is India going to achieve by going to the moon now? ''We are planning to study hitherto unknown topographical aspects of the moon, composition of lunar crust besides mapping the moon thoroughly using stereoscopy,'' scientists said. In fact, ISRO is closely observing Japan that too plans to launch a payload with ''penetrators'' that will be fired into the moon's crust. The penetrators will be embedded in the surface and will relay data on moonquakes, beside crucial topographical information. Explaining the commercial objectives of the mission, Joseph said: ''We are studying the potential of Helium-3 gas in generating power. Already experiments are on around the world on fusion energy. Using Helium-3 to produce power has great advantages. ''It is scarce on earth but abundant on the moon. Considering the huge costs and expected demand for energy after 2050, producing energy using Helium-3 fusion-reaction, even after transporting it from the moon, will be economical.'' He said that in 1999, the US alone generated 420,000 MW of electricity. This could have been produced by using just 40 tonnes of Helium-3. ''With our enhanced technological capabilities we too can help in this. It sounds very far fetched, but we are studying it,'' Joseph said.
