The Moon, as photographed by Louis Daguerre, 1839

I’m not kidding when I say I’ve been moonstruck since childhood. That’s when my parents dragged me out of bed on one sultry July evening. Mom opened the bedroom door, shook me and said, “Wake up! You have to see this!” Grumpily, I dragged my sleepy self down the hall and into the living room, where my parents, grandparents, sister and brother sat, glued to the TV. My seven-year-old self stared at the screen, impatient. After a few moments, Neil Armstrong hopped out of the LM and into history, followed shortly thereafter by Buzz Aldrin.

The whole concept seemed so wild to me. That giant Saturn rocket shooting them into space. Three men jammed into what seemed not much larger than a Volkswagen Beetle. Being able to see and hear them from an ever increasing distance. And then, the landing. Walter Cronkite’s gushing on air wasn’t much different from everyone in my house. Or the world, for that matter.

I didn’t really think about all the technology, or the training, or the money, or even the space race that evening. Other NASA missions came and went, and my family followed them all. But somehow, this one stood out from the rest. Three guys achieved something no one else has ever done then and since (although that will change shortly).

All I knew was that I wanted to be an astronaut. Desperately.

As the years went by, I shifted my interests to astronomy and learning the constellations, and the shifting planets in the nighttime sky, plus the occasional comet and meteor showers. I never did well in math, so I gave up my dream of becoming an astronomer. But my love for the offworld never faded, and I kept my sweet spot for the moon.

There’s nothing more entrancing than watching the glow of a full moon on a white blanket of snow, as the whitened trees glisten from its brightness. Or how a summer night feels so romantic with the moon sailing over the ocean. How welcoming the moon can be when it peeps out from a clearing sky, or transform into a mysterious red when it eclipses. Or blots out the sun and turns black.

Lots of sci-fi novels and movies use the moon as a backdrop or a plot device. It has religious significance for many. One can be mooned, have a moonface, or eat a moon pie, or wear a moonstone. Or be like Cher and Nicholas Cage and be moonstruck.

If you’re lucky and under the right conditions, you can catch the new moon in the old moon’s arms, or the old moon’s arm around the new moon. That means right before and after a new moon, there’s a thin ribbon of light, the slenderest of crescents, holding the dark side. Through a telescope or good binoculars, you can make out some details of the dark side too. This phase doesn’t last long, as it’s right before sunrise or just after sunset, and the moon is very close to the sun in the sky and very near the horizon.

If you catch it just at the right time, you can see an occultation, or the moon appearing to hide a star or planet. It’s literally now you see it, now you don’t. The moon slides in front of a celestial body, for a matter of minutes or hours. Then the celestial body magically reappears. It’s fascinating to watch.

During daylight, a moonrise might seem as if it’s almost see-through and blue. Spotting a full moon rising from a mountaintop is downright spectacular. You’ll never see something so big in your entire life. Or catching it rising over the ocean – the glow on the horizon, then a tiny, shy peep, as it creeps higher into the sky, a ribbon of light shimmering over the ocean’s surface, until, for a moment, the entire orb appears to be balancing on the horizon itself. Way cool!

I’ve already spent much of last and this week reliving the moon landing and the entire NASA early space mission by watching programs on PBS, or reading articles, or posts on my Twitter feed. I still marvel at this accomplishment.

But most importantly, I remember how unifying this singular moment was for our planet. How we all came together to marvel at such an achievement. It was an accomplished started out of competition and ended in peace. We need, not only as a nation, but as ambassadors of this legacy, to remember what good can come of scientific achievements, and to put aside all that makes us angry and frustrated, in order to move forward to use our discoveries to better the fates of all humankind.

trappist-7Trappist-1 System – NASA

By now, everyone’s heard the news – there’s seven new planets to consider in the universe. We’ve all read the headlines. Seven lovely orbs holding potential for life, only a mere 40 light years away! Why, that’s practically next door! And some of them hold the potential for life? Incredible.

While it’s nice to consider that we have an escape plan  to another world, it’s kind of unreasonable to expect to get to any one of these places anytime soon. Sure, we’re all expecting to hop on a space ship in the next couple of dozen years and arrive at planet du jour within a Einstein’s calculated period. And Lord knows that the folks behind Prometheus  practically guarantee travel to new Edens (although not without some pesky grey, hissing creatures with a penchant for sucking people’s innards and faces).

Are there wormholes to get us to these places quicker? Could be. Interstellar makes an excellent argument for that. If those wormholes do exist, the common folk won’t hear about them, at least not yet. Existing in theory and written about aplenty, I’ve no doubt these gateways to universal superhighways are around somewhere.

How then, is it possible to construct a vehicle to travel within the confines of a wormhole? Sure, we can throw a ship together – that’s the easy part. I’m wondering how a ship might be able to withstand whatever that wormhole throws at it – pressure gradients, temperature, forces binding the wormhole together. Or suppose the wormhole is a perpetual vortex that leads to nothingness? Once trapped inside, the travelers can’t break free and are subjected to extremes not even imagined?

Could there be different categories of wormholes? There must be. Just as there’s different types of highways, roads and streets, wormholes have characteristics. Some may be dead ends, short jaunts or long, winding roads. There could be ones that have celestial potholes, breaks, connect at junctions or turn back on themselves.

Suppose we do discover a wormhole in the neighborhood of Jupiter, as mentioned in Interstellar. Do we send our best and brightest through it just to see what happens? Do we travel to the unknown hoping to reap the benefits of what other places and methods of navigation can teach us? How do we steer our crafts, once caught in a wormhole if we don’t fully understand what they are in the first place? What is speculation and reality? Or will time trick us to believe there is a light at the end of the wormhole, only to find out we’re no longer able to function because of the forces of the universe bearing down on us? If we’re not able to return to Earth, what good is the journey to begin with?

Eventually, some intrepid group of astronauts will go forth to see what’s out there. We may never hear from them again. But they might find another system such as Trappist-1, and create a world that no citizen of Earth may ever be so fortunate to imagine.
