During 2008, NASA EDGE will be covering some very cool and exciting topics on exploration. We also will be highlighting some major achievements during the past 50 years. We would like to hear from you! Please post a comment on what you think are some of the most memorable NASA achievements over the past 50 years. Feel free to share any funny stories on missions or projects. We hope to get comments from the early days of NASA to the present. Maybe one of your comments or stories will make a NASA EDGE show.

"One of the biggest - and most talked about - stories in NASA history has been the moon landing conspiracy. That has to be one of the most memorable events in NASA history. I mean, the conspiracy theory has been tested over and over by independent conspiracy theorists and the results always conclude that Neal Armstrong did land on the moon and it wasn't some sort of government conspiracy - so get over it people!

The 50th anniv logo is ver' cool, I love it. Saw Peggy Whitson wearing a t-shirt with this logo on it on ISS. I want one, and it better be reversable! (Ask the host, he knows why Blair, it's the argyle sock thing again. Great minds, what can I say?)
Anyway, there are so many things NASA has done in the last 50 years, I can't think of anything I use daily that in some ways hasn't been touched by NASA. From cell phones to computers, medicines, foods, air and auto innovations and comfy astronaut foam beds, this tiny agency has powered the economy on 1/6 of 1% of the discretionary budget for our nation, amazing! Imagine if MORE money were available??

I wasn a secretary for most of that last 50 years. I loved every minute of it observing the beginning and ending of a lot of manned space flight programs from Apollo through Skylab, Apollo Soyuz Test Project, Space Shuttle then the communications era of Tracking and Data Relay Satellites. We don't want to let the engineers and scientists down (past and present) for all their hard work. Keep the money coming!!!

Some of my greatest memorable NASA achievements are:
* the birth of (NASA)-National Aeronautics and Space Administration on October 1, 1958 :) * The lunch of its first earth satellite (Explorer-I) on January 31st, 1958. * The successful Apollo 7 mission in October 1968. * The successful Apollo 8 mission, which orbited the Moon on December 24-25, 1968. * The successful landing of Apollo 11 mission on July 20th, 1969. * The successful of other crazy missions like Apollo 12,13,14,15,16,17 and all the other crazy missions. * The successful of building space rockets, lunching things and failing :) * Sending live animals into space with the launch of Challenger flight STS-51B on April 28, 1985 :) * the successful launch of the Hubble Space Telescope astronomical observatory into orbit. * And at last, the successful of celebrating 50 years of NASA :) haha
Thus are some of 10 achievements, please add yours so the total can be 50 ;) hahaha
I Just remember of all this, my first and last time I visited Kennedy Space Center (NASA) Florida in 2000, 7 years ago. I hope that I will visit NASA again and I hope the other next 50 years of NASA will be successful in Space age of exploration and searching for life beyond our planet earth and beyond our Galaxy-the Milky Way.

I have a nagging question about the Deep Impact Mission to Comet Temple 1. With the force of about 5 tons of TNT that was delivered to Temple 1, how much deflection to the orbit was the result of this impact. Could this cause Temple 1 to become an impactor itself? As I tell my kids 'What you do now determines what happens later.' Have we set the line of dominos on an unexpected track? Something to think about and I haven't seen any discussion on the subject.

I have to agree with Zara on the human spaceflight side. Neil Armstrong's first step on the moon will always be remembered. On the robotic side, I would say the Mars rovers are the greatest exploration achievements over the past 50 years. I believe they were only designed to last 3 months or so. Look at them now. They are still sending back awesome pictures and important data.
Just think what we will be saying 50 years from now!

50 years of NASA! Now that's cool! I had a star party on that day, with cake and stuff. It was fun. I think one of the most important lanuches was of the Apollo 11 to the moon! It was the coolest thing, even though I wasn't born then.

I think the most obvious one is landing on the moon. Some other great accomplishments would be the Mars rovers Spirit and Opportunity (concrete evidence of water on the surface of Mars at one point in time), the Cassini/Hyugens project (greating increasing our knowledge of Saturn and its moons), the Explorer satellite (our first orbiting satellite), Genesis (the first actual analyzation of material from our Sun), the International Space Station (the first major international cooperative mission in space), the Viking missions (the first spacecraft to successfully land on the surface of another planet), Deep Impact (the first interception of a comet), Stardust (the first mission to bring back material from a comet), GOES (a constant weather monitoring system that has greatly increased our understanding of the atmosphere), the Hubble Space Telescope (I don't think much of an explanation is needed there), the Pioneer spacecraft (the farthest human made object in the solar system), and Voyager (the first mission to analyze several outer planets in a row, among other things). Then again, I'm just a general nerd who thinks everything NASA does is amazing. :P
