Well, this is my last post recapping my time at the NASA Tweetup for the launch of the Juno spacecraft.  It was an amazing experience stuffed into two action packed days.  It's hard to imagine that I almost wasn't able to attend due to some scheduling conflicts.  Luckily, it all worked out and I was able to take part in this once in a lifetime experience.

Hanging out with space shuttle Discovery in the VAB

As I look back, I would have to say that the tour of Kennedy Space Center and the Cape Canaveral Air Force Station was the highlight of my time there.  The sights we saw will stick with me for many years to come.  Standing next to space shuttle Discovery, looking straight up the middle of the Vehicle Assembly Building, and driving by Launch Complex 5, where the American space program started, were the real highlights for me.

The guest speakers, demos and launch of the Juno spacecraft were a very close second, but the tour was really something special.  The best part about the guest speakers wasn't necessarily the content of their talks, but just experiencing their passion for their work.  These were brilliant scientists, engineers and astronauts taking time out of their busy lives to share their passion with 150 Tweetup nerds in a hot tent.  Pretty inspiring people to be around.

Tweetup participants in the tent

One aspect of the Tweetup I really enjoyed was talking to other participants.  It's great to meet people that share the same interests as you, and love to get in conversations about it.  There were people from all walks of life, with many different specialties, that all shared an interest in space exploration.  The comradery on our tour bus (1A/1B), the people I sat with in the tent, my dinner companions the first night, and the folks I met at the Endless BBQ were all wonderful.  All were great people, and I hope to cultivate relationships with them via Twitter and Facebook, and maybe even see them at future NASA Tweetups.

Vehicle Assembly Building

Even though I'm not one of the "NASA is dead now that the space shuttle program is finished" people, I did take away the feeling that NASA is alive and kicking.  As Charles Bolden said, the unmanned missions are the building blocks to the higher profile manned missions of the future.  In many ways, I think the data compiled by the unmanned missions is much more exciting than the manned missions.  The Juno spacecraft will travel for five years, over 400,000,000 miles from earth, and study a planet that might give us information about how the solar system formed.  That's pretty mind blowing stuff.

It's human nature to explore earth and space.  Unfortunately, society will find money for wars in the middle of a desert on the other side of the globe before they find money for space exploration.  I guess fighting is human nature too.  Many people don't realize that space exploration has had many technological advancements as side effects.  Sure, we can just save all our money, not explore anything, not advance as a society, and die not having learned anything.  I just don't see the point in that.  Some people don't see the big picture, but I'm glad to be one of the voices that shares my enthusiasm about space exploration.

I wasn't around in the 60's, but I read that the Apollo missions unified Americans as much as WWII did.  Luckily, politicians see high profile space missions as a unifying thing, so then they will find money for NASA.  When the time comes to send humans to Mars, I hope it will be like the Apollo program all over again.  Participation by both NASA and private space companies in space exploration seems like a cost effective way to push ahead.

150 NASA Juno Tweetup participants

As you may have gathered from my last ten blog posts about the Juno Tweetup, I had a blast (pun intended).  If you have the chance to participate in a NASA Tweetup, don't pass up the opportunity.  If you don't think a Tweetup for an unmanned mission will be as exciting as one of the past shuttle Tweetups, I think you're wrong.  Heck, the GRAIL Tweetup will have Sally Ride as a guest speaker!

Even though this is my last Juno Tweetup recap post, please stay in touch by following me on Twitter and keep an eye on my blog for updates. Writing these blog posts was very fun, since I got to relive all the highlights of my two days at Kennedy Space Center.  Thanks for checking out my blog, and I hope you enjoyed reading the posts as much as I enjoyed writing them.

NASA Juno Tweetup: day 1 - Launch Complex 17 tour

Read my previous blog entry in the "NASA Juno Tweetup" series: "Day 1 - arrival and guest speakers"

Launch Complex 17 with a Delta II Heavy inside the service structure

After a wonderful morning getting to know my fellow Tweetup participants, and hearing stimulating talks from many of the Juno and launch services team members, it was time for our bus tour of Kennedy Space Center.  This is a portion of the Tweetup that everyone has been very excited about.  This wasn't the KSC tour that you can purchase from the Visitor's Complex.  This was a tour of Kennedy Space Center and Cape Canaveral Air Force Station sites that only employees really get to see.  The tour consisted of visiting Launch Complex 17 to see the Delta II Heavy rocket that will launch the GRAIL spacecraft, the Atlas V Spaceflight Operations Center run by ULA, Launch Complex 41 to see the Atlas V rocket with Juno on top, and finally the Vehicle Assembly Building, which contained a surprise for all of us.  You'll read about the last three sites in subsequent blog posts, because this post is all about Launch Complex 17.

After lunch, we all piled in three buses and headed off in different directions.  I was on bus 1A (I'll explain that in the next blog entry about the Atlas V Spaceflight Operations Center), which started off on our journey to our first stop at Launch Complex 17, which is currently home to a Delta II Heavy rocket that will launch the GRAIL spacecraft to the moon on September 8th, 2011.  I was lucky enough to be sitting near Dave Allen, a fellow Tweetup attendee, who really knew his KSC/Cape Canaveral history.  He was giving the back of the bus a great, impromptu tour as we made our way to LC-17.  On the Air Force Station, we drove by what looked to be one or two of the space shuttle solid rocket boosters.

Dave also made sure to point out the location of Launch Complex 5, which was where Alan Shepard left earth for 15 minutes on a Mercury Redstone rocket in 1961, becoming the first American (second human) in space.  Based on the number of rocket failures the American space program experienced in the early years, I think it's safe to say that Alan Shepard is a daredevil.  They were still unsure of the effects that space would have on a human, and especially unsure if the rocket would even get off the launch pad successfully.  Shepard had plenty of time to think about all of this, while the techs on the ground worked out issues with Alan in the capsule on the launch pad for over four hours.  His frustration with the delays caused him to say one of my favorite phrases to the crew:  "light this candle."

Launch Complex 17 A and B

We finally arrived at our first stop:  Launch Complex 17 on the Cape Canaveral Air Force Station.  This launch complex has been home to the Delta launches since the early 60's.  Currently, pad 17A isn't in use, but 17B is, and was loaded with a Delta II Heavy rocket that you can see inside the support structure.

Looking closely, you can see the many solid rocket boosters that surround the bottom of the Delta II Heavy.  This rocket is awaiting delivery of the GRAIL spacecraft that will study the moon's gravitational fields to determine the moon's interior structure.  Actually, the GRAIL spacecraft is really two twin spacecraft that will both orbit the moon together.  FYI:  GRAIL stands for "Gravity Recovery and Interior Laboratory".

When the GRAIL spacecraft is delivered, it will be placed atop the Delta II Heavy right at the launch pad.  The right side of the support structure contains a crane that will lift the spacecraft to the top of the rocket.  When it's launch time, the support structure rolls out of the way to expose the rocket on the pad.  Launch is set for September 8th, 2011.

While we were at LC-17, we were treated to a quick talk about the GRAIL mission and the Delta family of rockets from a NASA employee and a United Launch Alliance employee.  I really wish I remembered their names, but I didn't write them down.  Very interesting guys that gave us some great info.  ULA is the private contractor (owned by Lockheed Martin and Boeing) hired by NASA to coordinate the launch logistics for the GRAIL mission, and also the Juno mission.  ULA produces the expendable launch vehicles (Delta II, Delta IV and Atlas V rockets) that launch NASA unmanned spacecraft missions.  It was interesting to see how the private companies are now so involved in the space program.

The ULA employee made sure to point out the fact that the Delta II rocket has had a 100% success rate.  I'm not sure exactly what he was referring to, since a Delta II rocket exploded shortly after takeoff from LC-17 in 1997.  I'm guessing he was referring to a different, more modern version of the Delta II that hasn't experienced a failure.  The ULA employee did mention that there are more Delta II rockets built and ready to go, which was a reference to the fact that NASA (and the Air Force) may or may not decide to continue using the Delta II.  When asked about ULA's competitors in the private space flight market, he posed the question:  what would you rather trust to keep your your astronauts and expensive cargo safe, a rocket that has had two test flights (SpaceX) or rockets (from ULA) that have had hundreds of successful launches?  He also stated that all the GPS satellites we use on a daily basis were put into orbit by Delta rockets.  The NASA employee did make a funny statement when someone asked about the condition of the pad right after a launch.  He said it's just like when you throw a BBQ at your house, you come out with the power washer the next day and flush everything away.  He said it's surprisingly cleaner than you think, but still does require a good cleaning.

So far, our KSC and Cape Canaveral Air Force Station tour was off to a great start.  Next stop, the Atlas V Spaceflight Operations Center to see ULA's firing room and to stand 15 feet from the Atlas V rocket that will launch the Mars Science Laboratory mission with the Curiosity Rover in November.
