Back with some science
December 30, 2009
The holidays obviously consumed my life to the point that I haven’t posted in over a week. Sorry ’bout that. I also haven’t shared any good sciencey tidbits in a while, so here you go:
I recently saw James Cameron’s latest epic Avatar. I won’t get too involved with reviewing the film as I’m no film critic by any means, but I will say this- it’s beautiful. The animation is astounding and most notably, the landscape is gorgeous. The dialogue and storyline is utterly pathetic. It’s basically the same story as Last of the Mohicans, Fern Gully, or Dances With Wolves, only this time it’s injected into a sci-fi mold. That being said, I always can enjoy that story to some degree no matter how many times it gets retold and rehashed. What is pretty cool about the movie is the science behind it. There will always be a big gap between “movie physics” and reality, but the over-arching idea of a habitable moon similar to Earth orbiting a gas giant similar to our own Jupiter in different star system is entirely plausible. The fact that the moon’s atmosphere is toxic to humans makes it slightly more realistic, along with the reduced gravity resulting in the native animal life being mostly large compared to that of Earth. Space.com has more on the science of Avatar’s Pandora.
I’ve mentioned on here before that NASA and the European Space Agency have teamed up for the next decade or so of Mars exploration. The exact timeline and details of that effort are now beginning to come into focus, thanks to the recent discovery of a constantly replenished quantity of methane in Mars’ atmosphere The first step will be a new orbiting observatory launched in 2016 that is specifically equipped to further explore the possible sources of this methane, and map out exactly where it’s the strongest. Also on this first mission will be small lander designed to test the parachute/thruster landing system that will be used on the future missions involving the “real” landers/rovers. Those rover/lander missions will be launched in 2018, and will be specifically designed to search for signs of life. Recent developments in the theories about the possible source of the methane have started to lean more towards microbial life, probably living under the surface. That’s very exciting. More on this at Universe Today.
What kind of blogger would I be if I didn’t have some sort of “year-in-review” post? Unfortunately I haven’t had the time to come up with anything myself, but here are a couple of 2009 recap posts from other science blogs that you might find interesting:
Live Science: 9 stories we love, and hated, in 2009.
Space.com: The 9 top spaceflight stories of 2009.
Some of probably already know this, but I’m currently in the process of moving. Megan and I are renting a small house near Germantown, and though the house will be awesome once we get settled in, the timing really sucked. I can’t think of a worse possible time to be moving than during the holidays. So posting here will probably be limited until next week.
