I talk about Star Trek during the first week of every class I teach. I ask my students about their attitude towards "science", and two words invariable come up: boring and hard. As we continue a discussion about how science works we talk about how science is a body of knowledge, a codified organization of facts and principles that we agree are "real" despite the cultural background of anyone studying science. In other words, we can believe whatever we wish. We can even decide, for instance, to deny the existence of gravity. But no matter how hard one believes that gravity isn't real, one will still drop like a rock if one steps off a cliff. So we start to collectively begin to understand how science works. But still, there are challenges in learning and mastering science. It can indeed be hard (and maybe boring, but I can't imagine how...). On the other hand, what a privilege to be living in the times that we do, with the knowledge that we have access to!

That's where Star Trek comes in. Episode after episode imagined "strange new worlds", and most of them included bizarre planets far removed from our own. To me, back in those primitive years before the Hubble Space Telescope and the Voyager satellites, the science of astronomy was an exercise in frustration. I would head to the library week after week, checking out every astronomy book in the stacks, hungering to understand our own Solar System. And we knew so little! Venus was shrouded in clouds. Mars had visible features, but they were unidentifiable from earthbound telescopes. Jupiter and Saturn had spectacular clouds, but their moons were simple points of light. Nothing could be discerned on their surfaces. Neptune and Uranus were small disks, and diminutive Pluto was a dot of light. I wanted to know more!

The advances came so slowly (at least to this young growing child). The first satellite missions to Mars in the 1960s revealed surface features (and a lack of alien civilizations). And in the late 1970s, the two Voyager spacecraft began the grand tour of the outer gaseous planets. It was an excruciating wait as the small satellites passed first Jupiter, then Saturn, followed by Uranus and Neptune (years passed between each visit). Then, knowing the satellites had arrived, there was the excruciating wait for the pictures to be downloaded and processed. It was worth the wait. The pictures and data were astounding, revealing worlds never imagined by humans, even on Star Trek! Volcanic moons, ice moons, cratered moons, moons with atmospheres, rivers, lakes and seas. It was a menagerie of strange new worlds, and they were in our own back yard.

And what about all that cool Star Trek technology? Who could have believed that some of the craziest bits of technology from the original show would be commonplace less than fifty years later. Communicators and tricorders became the flip-phones and smart phones and tablets of today. Essentially the entire library of human knowledge can be carried in anyone's pocket (and what do we do with it? Send each other pictures of kitties...priorities!).

And this is what keeps me going every day as I approach my thirty-fifth year in the front of a classroom. The adventure in space continues, as it does in all areas of science, including my own in geology. Just in the last year we saw Pluto up close for the first time, as well as the largest of the asteroids, Ceres. More planets and planetoids remain to be discovered. The launch of the Webb Space Telescope in a few years promises to extend our vision to the edge of the known Universe. It is an incredible time to be alive! I feel privileged to have seen a vision of adventure in outer space through the many permutations of Star Trek, as well as seeing a vision of humankind at its potential best. But I'm glad I'm still around to see the real human adventure of science exploration continuing.. And that's what I hope my students will come to understand as well.
