Slice of PIE: Beyond the Pull of GRAVITY


I am sure that most of the people reading this know about Sandra Bullock, George Clooney and the (literal) smash hit, GRAVITY. If you don’t, then either go and see the movie or read a half dozen of the reviews.

You’ll find that it will most likely be one of the contenders to beat in the 2013 movie awards. I’d love to add my raves, but I’m going to restrain myself and talk about something else that occurred to me.

The accident, as anyone reading this will know, takes out a space shuttle in the middle of a mission, the Hubble Telescope, the International Space Station, and the Chinese Space Lab, Tiangong 1. As well, it clears out most telecommunication satellites, cell phone relay satellites, weather satellites, spy satellites...and just about any other satellite you care to name.

So let’s go beyond GRAVITY. Beyond the spectacular ending and the subtle and not-so-subtle symbolism Alfonso and Jonás Cua­rón imbue this movie with, a thought leaped into my head after some reflection.

Is this what Humanity needs? I have a resounding answer as well: YES!

How so?

First of all, let me share the idea on which the movie GRAVITY is predicated. Called the Kessler Syndrome, it is named after the NASA scientist who first proposed it in 1978. Because every launch of every satellite creates “junk” in Earth’s orbit, this space garbage has been accumulating since October of 1957, when the old Soviet Union launched the first artificial satellite. How does that number tote up today? “Currently, about 19,000 pieces of debris larger than 5 cm (2.0 in) are tracked, with another 300,000 pieces smaller than 1 cm below 2000 km altitude.”[1] A Kessler event clears much of the space near Earth of operational satellites, crippling...well, just about everyone who uses a cell phone or any other form of communication on the planet.

At one point in the movie, astronaut doctor Ryan Stone is drifting in silence and stumbles across a radio broadcast – in AM. That’s all that’s left after the catastrophic Kessler event. From here I'll jump to the very, very end of the movie, where Humanity in the form of Sandra Bullock crawls out of the primordial ooze. I will note that the location of said crawl out is not only significant, but is the key to what happens next.

At this point in the fictional movie’s history, rescue is not imminent. Despite queries to indicate that at least some of Earth’s satellites are still active, no one is really going to be able to figure out who was landing and where they landed. Presumably the Chinese have some idea as they were the ones who programmed the landing protocol of the Shenzhou reentry craft, though I don’t recall any Chinese radio chatter…

Now what?

Dr. Stone is in the middle of nowhere. She has to walk to get where she’s going.

Such a Kessler event might so badly disable the Human psyche regarding our presence in space that we never again send people there. Space exploration becomes a robotic endeavor leading to ever more complex machines flying into space as Humanity pulls ever more into itself until we no longer care about space except as a medium through which to call each other long-distance, text about our bowel movements, find ourselves when we take a wrong turn to grandma’s house, or want to know whether or not to water the lawn tonight. This is certainly a possibility and we’ve shown ourselves capable of such a reaction time and time again – turning back from the future with our tail between our legs. This certainly happened after Three Mile Island and Chernobyl. Who knows – such may have been the Neanderthal’s reaction to the discovery of fire.

Or a Kessler event may precipitate a renaissance. With the orbital slate swept clean, we might cooperate and send up a laser sweeper to finish the job chance started. Once that clears the way – and the world is cowed by the catastrophic loss of texting, bowel reports, grandmother visits, and lawn care – real money may fuel a race back into space to not only reclaim what was lost, but make sure it never happens again.

An international space station more along the lines of the one in 2001: A Space Odyssey might grow quickly to oversee the orbital cleanup, provide a long-term monitoring solution to the buildup of space debris, create a true home of Humans in space, and create a new platform for interplanetary exploration. An explosion of technology like this occurred after WWII – why not in the wake of an Earth orbit tragedy?

It could do either – and I’m pretty sure anyone reading this can guess which one I favor. Anyone else have a thought?
