I'm starting to feel a little like Han Solo here...

You know...every time he desperately needs to get away in the Falcon, the darn hyperdrive fails.

Well, as I was anticipating writing a long, lustrous update this week...circumstances conspired against me again.  There's been major flooding here in our part of the world...including right here at the Virginia Living Museum.  We took a very serious flash flood last weekend, with water flooding the lower level of both of our museum buildings.

Water pours over the tops of our floodgates and through the doors to the lower level of the museum.  Approximately a foot of water entered overall in the main museum building.  The Wason Education Center took on about 3 feet of water.

Fortunately, the planetarium was spared any major damage.  Unfortunately, little else was.  We've reopened the museum to the general public, but the lower level exhibits remain closed.  To offset this, admission has been reduced by $5 and the planetarium is included in your general admission ticket (that saves you another $4!).  So if you've ever wanted to stop by and check out a show...now's a great time.  Plus your admission fee and any donation you can make will help us rebuild the lower level of the museum.  Estimates of the total damage are still being made, but believe you me, there's been a lot of damage.  Another great way to support us is to come on out to our Star Party & Laser Light Night on September 8th!  The planetarium and observatory are still in great shape, so we'll be open and hopefully enjoying some clear skies and some great music.

Also uppermost in my mind as I hastily update is the painful loss of Neil Armstrong this past Saturday.  Armstrong was the first man to set foot on the Moon, and his death at age 82 has made me realize that soon there will be very few people left who remember seeing the Apollo Moon landings, and even fewer who actually participated in them.  In fact, of the 12 men who walked on the Moon, only 8 are still alive today (besides Neil Armstrong, James Irwin died in 1991, Alan Shepard died in 1998 and Pete Conrad died in 1999).  As this generation passes, and the American space program shrinks into obscurity,  we run a greater and greater risk of forgetting how to accomplish these amazing achievements...or even disbelieving that we ever did.  Already polls show that some 6% - 20% of Americans do not believe we ever landed on the Moon.

Such numbers are a slap in the face to the 12 brave men who actually did indeed walk on the lunar surface.  I hope we'll be able to get ourselves back into the space race in the not too distant future.  I hope that our first tentative steps out into the solar system won't turn out to be our last.

And finally, Godspeed, Neil Armstrong.

I'll try again in two weeks.  You hear that, ship?  Hold together!
Carpe noctem!

Giving Thanks

Happy Thanksgiving everyone!  Since I'll be off tomorrow, preparing to enjoy the holiday with my family, I figured I'd post a day early, and keep it all on the Thanksgiving theme.

As you've likely come to expect from this blog, there also needs to be a generous dollop of humor, so in honor of Thanksgiving and with apologies to David Letterman...

From the home office in Milliways, the Restaurant at the End of the Universe, here's my Top Five List of spacey things I'm thankful for this Thanksgiving.

5. The Abbitt Planetarium
Yep, I'm thankful for my job!  And not just for the usual it-pays-the-bills reasons either.  I'm one of those lucky people who truly has their dream job.  I get to work with people of all ages and share with them my love of the universe.  I get to exercise my creative drives and make shows in the planetarium on numerous different topics.  It's like being a Hollywood director without the pressures of Hollywood.  What more could I ask for?  And thank you to all of you who come to visit us and make it possible for me to continue to do what I love.

4. The Hubble Space Telescope
Hubble is truly one of the most remarkable spacecraft ever launched.  It's the telescope with 9 lives (at least!) and has provided us with innumerable stunning images of the cosmos.  It has survived not only the rigors of being launched into space aboard the space shuttle, but also numerous servicing missions designed to repair and upgrade its instruments.  When the initial flaw in the primary mirror was discovered shortly after launch, many people figured the Hubble was a loss.  Thanks to some amazing work by both engineers and astronauts, Hubble's flaw was repaired and for over 20 years this school-bus-sized scope has continually made our jaws drop with its incredible images.

Hubble is in decline now, since NASA has retired the space shuttle - the only vehicle which could be used to service the telescope.  Over the coming years, Hubble's systems will slowly degrade, until a final critical failure of some kind renders it useless.  Its successor, the James Webb Space Telescope, is mired in funding problems as NASA struggles to maintain itself in these fiscally trying times.  Whether JWST makes it up or not, when Hubble images its last, I for one, will shed quite a few tears.  No other instrument, before or since, has done what Hubble can - inspire us all with wonder at the visions of the universe it provides.

3. The Apollo Missions to the Moon
We've been to the Moon.  Men from Earth have stood on the surface of the Moon and looked up at the fragile blue planet we call home.  It was real, we went there.  It was not, as so many people believe, an elaborate hoax.  And it is one of the most inspiring stories of human exploration ever.

Exploration is always challenging.  But in reaching for the Moon, we had to overcome seemingly insurmountable obstacles.  There is no water or air on the Moon.  Gravity is dramatically less, so machines behave in different and unexpected ways.  We had no idea what the surface of the Moon was like, or how men would react - physically and psychologically - to being in space or on the lunar surface.  And yet, in the space of a decade, we went from dreaming about it to being there.  I hope one day, NASA will be able to have that kind of drive and vision again.  If you don't know the story of our journey to the Moon - check it out.  It's worth it.

2. The Night Sky
There's something entirely captivating about a dark night sky.  Looking up at the stars is a wonderful, peaceful thing to do in a world that sometimes overwhelms us with activity.  And sharing it with someone you love, or even someone you're never met, makes the experience all the more special.  My daughter and I have looked at the sky since she was a tiny baby.  If you've never enjoyed a dark night sky - here's a goal for the new year.  Attend a star party.  Look through a telescope for the first time.  Just go outside one night and look up for a while.  And when you do, remember that all of humanity shares that sky with you.  No matter how far away, no matter how long ago they lived, everyone everywhere has seen the same stars that you can see just by looking up. (I miss you, Dad.)

We're in danger of losing our night skies forever as we turn on more and more nighttime lights.  Losing the sky means losing a powerful part of our heritage.  Don't wait too long to see it - or it might not be there for you to enjoy.

And the Number One spacey thing I'm thankful for this Thanksgiving...

1. The Mars Curiosity Rover
We're headed back to Mars!  Mars is a simply fascinating planet, and our exploration of it has only made it seem more intriguing.  While we've found no canals or war-like Martians, we have found tantalizing evidence of massive amounts of water having once covered the Martian surface...and even indications that there once may have been...and even yet may still be...life on our rusty red neighbor.  The Curiosity rover is due to launch on November 25th, with a eye to landing on the Red Planet this fall.  I can't wait to see what amazing new discoveries it will show us.  Stay tuned!

I wish you all a safe, happy, and joyful Thanksgiving!

Are Aliens All Wet?

Greetings all!  Yes, I know, I'm a day early.  I decided to post today because I've got the day off tomorrow, and I'm spending it with my daughter.  So...let's take a question.

My friend Pam posted the following:

Kelly, why is water the determining factor in finding life on other planets? Doesn't that limit our definition of life to a terrestrial, Earthly paradigm? Couldn't other forms of life exist that require a molecule other than water for survival? 

So I thought I'd talk a little bit about this one (hence the title!), as it's an excellent question (thanks Pam!).  Simply put...yes.  And yes.  It's entirely possible that some kind of lifeform could exist that doesn't require water, and in fact, requires some other compound for survival.  So the question becomes...what would that lifeform be like?  How could we test for it?

You see, all of our physical searches for life beyond our planet have involved robots, which think like a computer.  We can tell the robot to test if certain conditions are met, and it can tell us yes or no.  So what conditions do we program it to look for to see if life is present?  Well...the only life we know requires water.  We know that life forms that require water generally do similar things, like respirate, produce certain kinds of waste products, reproduce themselves and things like that.  These give us parameters to test.  Life based around something other than water is so foreign to us, we wouldn't even know what to begin to test for!  So we make the decision to search for "life as we know it" - that is, water and carbon based.  While this definition limits the kind of lifeforms we are likely to find, it does at least give us a starting point to work from.

So the next question becomes: where can we find water?  Well, water can be found in a whole lot more places than just Earth.  Come visit the museum for our daily 12:30pm planetarium show "Oasis in Space."  It's a beautiful and exciting full-dome program that takes you on a journey through our solar system searching for water.  You'll be surprised at how many places water is hiding right close by!

But let's face it...any life we find here in our solar system is probably going to be minor - something like bacteria, plants, or maybe fish.  When most people talk about aliens, they mean the "take me to your leader" variety...a sentient being that we can carry on a conversation with.  If such highly developed life were present elsewhere in our solar system, we'd probably already be aware of one another.

So what about life on planets beyond our solar system?  There are some 500-plus confirmed other solar systems out there...and the numbers are only going to get bigger.  NASA's Kepler mission is in orbit right now, identifying potential planets, with over 1200 now awaiting confirmation.  Some of them are even approximately the same size as Earth.  Does this mean they are inhabited?  We can't say for sure.  These stars and their attendant planets are hundreds or even thousands of light-years away, and it will be a while before we can figure out if any of these planets have water, let alone support life.  And keep in mind - Kepler is surveying only a tiny portion of the cosmos:

So just imagine how many planets there must be in the entire Milky Way galaxy!  That's a lot of planets to check out...so if you're waiting for E.T. to phone home...well...you might want to put the phone on vibrate and go catch a movie in the meanwhile.

Thanks again to Pam for a great question!  And please folks, feel free to post whatever questions you have in the comment section.  I look forward to hearing from you!

See you again in two weeks!
Carpe noctem,
Kelly
