Eyes on the Moon!

Hey Space Bloggers!

Put our old friend THE MOON on your agenda for 2012.  That’s right, we’re back. GRAIL A arrived at the moon last year (also known as yesterday – December 31st, 2011) and GRAIL B will enter lunar orbit today, January 1, 2012.

In case you’re wondering (like I was), GRAIL = ‘G’ for Gravity, ’R’ for Recovery,  ’A’ for And, ‘I’ for Interior, and ‘L’ for Laboratory.  If you think GRAIL A and B are lame names, you’re not alone. NASA has asked kids for some help (duh) and will announce new names any day now.

But GRAIL A and B, by any name, are pretty sweet. Together they will open a window to the inside of the moon. NOT by blasting a hole through it. (Scientists are much trickier, and smarter, than that!)  GRAIL A and B will work together like two eyes, but instead of seeing ‘light’, they see ‘gravity’. By focusing in on the changes and variations of the moon’s gravitational field, they will be able to look deep beneath the moon’s cratered surface.

With a clear picture of the whole moon, inside and out, scientist’s hope to understand what makes the moon, well ‘the moon’. And they might also figure out just how the Earth and moon formed and got locked together almost 5 billion years ago.

 

 

P.S. SpaceBlog is taking a short break.  There will be no new posts during January, but if you have questions or comments, write in – I will always respond. And I’ll be back with a post February 1st, hopefully with new news from THE MOON!

Space Game! Where in the Solar System is Destination Twelve? The long awaited conclusion…

Hey Space Bloggers!

Welcome back for the merry (I hope) conclusion to the D12′s tale of woe, The Very Lonely Planet. When we left D12 he was thinking rather unpleasant thoughts about the intrepid space explores (actually, he called them ‘parasites’) from his little sibling Earth.  (That would be us.) He called us ‘impertinent’ just because we visited some of his siblings, being, you know, intrepid space explorers. And he tried his best to ignore us.

D12 turned his back as Earthlings first visited their own moon.  Who cares, what goes on between a planet and its moon, D12 thought as he continued on his great circular journey.  Except he had to admit it was shocking. Remarkable, really. Parasites from one planet jumping off and flying to another celestial body. It had never happened before in all the 5 billion years D12 had been watching.   But still, it has nothing to do with me, D12 told himself.

He tried not to notice as the ‘parasites’ got more daring.  10, 15, 20, 50 times they blasted off his little blue and white brother, most often heading toward its moon, to be sure, but starting to swoop on past, out to the other rocky planets near the sun. First, they visited his little sister Venus. Well, that was no surprise. She and Earth had always been close.

Then of course, that brassy, upstart Mars. All rock and no air, thought D12 disdainfully. I’m much more interesting than that. But still, he didn’t much care about his small, rocky siblings always in the Mother’s bright light. But when those ‘parasites’ left the inner planets behind and flew straight through the asteroid belt to Jupiter—Well, that could not be ignored.

credit: NASA

Jupiter is one of US, he thought. A BIG one. In fact the biggest. Was that it, he wondered. Was that why they went to all that trouble? And it really must be a lot of trouble, he had to admit, for those tiny, minuscule, insignificant creatures from Earth to overcome the tremendous force of gravity; And then to navigate huge distances, many times bigger than their own orbit, through the cold vastness of space. What must it be like to be visited by creatures who cared that much? D12 wanted to know.

So he watched. And he waited. And with every spin on his axis he checked to see what they would do next. He was watching when they traveled from Jupiter, to Saturn.

Ahh, yes, he thought. Of course they would want to see Saturn up close, with those rings. He had rings too.  All the BIG ones did. But Saturn had R I N G S ! He had to admit that Saturn’s rings were truly spectacular. After seeing them, he worried, would they bother to come visit me?  And for the first time in the eons since his birth, he questioned himself. Am I big enough, he wondered, or bright enough, or blue enough maybe, to interest the Earthlings (yes, he stopped calling them parasites).

He wondered, and again he waited.  And finally, after many spins on his axis, he saw them leave Saturn. But where were they going? He wasn’t sure.

credit: NASA

He had watched many rocks move through space and learned to judge their paths, but these Earthlings were different. They would fall through space like any other object, and then suddenly, with a burst of fire, veer off unexpectedly.  Maybe, just maybe, this time… No. They went to Uranus. And his hopes fell. You see, they were nearly the same, D12 and his almost twin. After visiting him why would they want to go all the way on to D12? He was so much father out. Almost to the edge of the great black, emptiness. Almost beyond the reach of even the great Mother Sun.

But still he watched.  He turned on his axis 1000 times, 1500 times, 1700 times. And then, finally, they came.  They didn’t stop.  Well, they couldn’t.  But they took pictures.  Lots of them.  In fact, D12 realized to his utter amazement, they took 10,000 pictures of him and his moons.  But what did they see.  What did they think of him?  He had to know.  He listened ever so carefully.  He sensed the electromagnetic waves that pulsed slowly and softly from the tiny ship.  And then, for the first time in 5 billions years, he saw himself through the eye of another.

And Neptune glowed.

Space Game! Where in the Solar System is Destination Twelve? (day 3)

Hey Space Bloggers!

Today we’re going back to Destination 12 for a new clue – a story clue! So just sit back, relax, and listen – well actually you’re going to have to read it yourself, but you get the idea.

Once upon a time, D12 was a very lonely planet.  At least he thought he was lonely. He must be, because he never got any visitors.  For eons and eons this didn’t bother D12, because he didn’t know what visitors were. How would a planet know such a thing? None of his siblings ever had any visitors either. Then, in the last half-billion years or so, he started hearing rumors that one of the little planets (in fact, it was the tiny blue and white one that always hung around up close to mother sun) had developed a bad case of parasites – Yes!

credit: Maniac World, South Park

Creatures living in its seas! Then walking across its surface!! And recently, even flying through its atmosphere!!!  (talk about a bad hair day!) Well, at first D12 just laughed at these stories.  That, he thought smugly, is what happens when you never go off on your own.  Sure, it might be nice to bask in the warm glow of Mother Sun, but after a few billion years or so, one really should grow up and fend for oneself! Not that D12 was completely on his own.  He still felt the sun’s gentle gravitation tug, and solar winds. But he didn’t rely on her for everything like some of his siblings. He, at least, managed  to make most of his own heat. He was very satisfied with his superb icy surface gradually thinning into a lovely, slushy atmosphere. Who wanted a bunch of clumsy, unpredictable creatures messing around with such perfection?

Credit: NASA STScI

Then he heard that the parasites had started traveling.  That’s right, jumping right off the third planet and flying through interplanetary space, where only tiny particles, and occasionally, asteroids  and comets dared to roam. Outrageous!  That was what D12 thought at first.  It goes against tradition! Yes, when they were young protoplanets and liked that sort of craziness, there had been lots of rocks zipping around the neighborhood. But for several billion years at least, it had been quiet. Extremely quiet.  Now these upstarts from his little sibling had the nerve to disturb the long cold peace, to orbit some of his brothers and sisters even, and touch their tummies.

credit : NASA

Quite impertinent! The very definition of bad manners! D12 turned on his axis away from such nonsense, and continued his very long orbit, just glad that such parasites would never reach him.

Or would they?

Check back next week to hear (well, you know, read) the conclusion of The Very Lonely Planet.

Space Game! Where in the Solar System is Destination Twelve? (day 2)

Hey Space Bloggers!

Finally, something to be thankful for! Here it is, straight from the icy clouds of Destination Two, your day 2 LIMMER-IDDLE: (sorry it’s late)

Some find me divine, that is true,

And my aspect, a deep ocean blue

Which might possibly be

Why you Earthlings named me

For that god of the sea, You-Know-Who!

Thank you D10 for that uh, seaworthy clue.  I’m sure some Space Bloggers are fishing around for answers already!

Space Bloggers, be sure to keep those guesses and comments coming in. We’ve got a lot to talk about!  And check back next Tuesday for another clue to that 2 week old dilemma, Where in the Solar System is Destination Twelve???

Space Game! Where in the Solar System is Destination Eleven? And the location is…

Hey Space Bloggers!

Congratulations to Dr. Spaceman for getting us off to a great start!  After seeing those crazy, enormous Northern Lights on day 1, he thought Destination 11 might be a planet. Excellent thinking!  He must know that such aurorae are caused by the solar wind flowing across a magnetic field.  The sun provides the wind, but it takes something BIG, like say a planet, to form a magnetosphere.

Then D11 himself spoke up in day 2′s limmer-iddle  and revealed that he is ‘a huge gas filled ball’. So I’m sure that got a lot of you thinking GAS GIANT.

But which one? (you asked yourself) After all, there are four.  Then you noticed another clue in the limmer-iddle; D11 said he was ‘not the biggest’. Okay, that knocks out Jupiter. And we are down to three.

From day 3‘s post you cleverly deduced that the ‘arms’ Galileo saw were really rings.  You then checked and found out that, while all the gas giants have them, only one has bright reflective rings that can be seen from Earth.

But what really cinched it for Archimedes was finding out on day 4 that one of D11′s many moons is our own Destination TenTITAN!

That’s right, Space Bloggers. You guessed it.  Destination Eleven is none other than that lighter than  water, sparkling gem among giants…

Special Halloween Edition

Hey Space Bloggers – Sorry, but I have to interrupt Space Game this week to bring you a special report:

It all started when these scientists started talking about this weird neutrino (very, VERY small particle) that supposedly goes faster than the speed of  light (186,000 miles a second, that’s EVERY second).

At first I thought, who cares, right? I mean, so this tiny thing goes really fast? What’s the big deal?

Well, I asked Dr. Spaceman  that question and he told me that it is a VERY BIG DEAL because it breaks the law! Well, technically it breaks a theory, but it’s practically a law because its been proven right like a gazillion times. Of course, I’m talking about Albert Einstein’s Theory of Relativity (probably the most famous theory ever!)

Photo acknowledgement: Institute for Theoretical Physics, Frankfurt, Germany

According to this theory, nothing–not a bullet, or a plane, or even a tiny neutrino–can go faster than light. If it could, well lets just say things could get bad – or cool – depending on whether or not you like the idea of .     .     .

Crazy, huh? I mean, if you think about it that means that you could  turn a corner one day and run into a flesh eating pterodactyl taking a vacation from the Mesozoic era, or maybe a curious robot from the 27th century coming back to dissect primitive humans like us.

But I wouldn’t think about that if I were you,  especially not tonight when you’re out trick or treating with all those ghosties and goblins. I’m sure none of them are real live monsters from our primordial past. It’s not at all likely they could be alien zombies who invade Earth in a hundred years and then come back to get US.

I mean, don’t worry.  It’s just not possible. Albert Einstein said so and–

HEY, who is that old guy across the street with the frizzy white hair, big nose, and funny mustache??? It couldn’t possibly be….I mean, he died a long time ago…unless… Excuse me, Space Bloggers. I have a few more questions for Dr. Spaceman.

But before I go, there was something I wanted to tell you… Oh, yes! For the exciting conclusion to Space Game: Where in the World is Destination Eleven? be sure to check back next week, or will that be last week? I am so confused!

Space Game! Where in the Solar System is Destination Eleven? (day 4)

Hey Space Bloggers,

After reading the ‘day 3′ clue, I’m guessing that you are almost as confused as Galileo was to see that Destination Ten’s ‘moons’ suddenly disappeared, only to reappear four years later as ‘arms’.  Right?

Galileo Galilee

Hint#1: What Galileo saw was neither ‘moons’ nor ‘arms’. For today’s post, we’ll just call them ‘things’.

Now I’m going to tell you how the ‘things’ did their disappearing act. Then I bet you can tell me just what those ‘things’ really are. Ready?

Here goes: When Galileo could NOT see the ‘things’, he was looking at them edge-on and they were too thin to see through his homemade telescope.  When he COULD observe them, the ‘things’ were tilted at an angle and he could easily see their wide expanse through his telescope.  So that means that the ‘things’ are large and wide, but very thin, sort of like a pizza.

So now do you know what Galileo saw?  [Hint#2: It rhymes with 'things'.]

Christiaan Huygens

But don’t think this means that Destination Eleven doesn’t have moons.  Because it does. Lots. The first one, TITAN, was discovered in 1655 by Christiaan Huygens, a Dutch astronomer.

Just a few years later an astronomer named Cassini discovered four more moons, IAPETUS, RHEA, TETHYS, AND DIONE. Since then, 13 more have been discovered bringing the number of moons orbiting Destination Eleven to a grand total of 18.

So long for now, Space Bloggers. But be sure to check back next week when I announce the answer to that burning question: Where in the world is Destination Eleven?  That is, unless YOU write in with answer first!
