Atomic super robot in space!Posted: July 10, 2012
Yeah, yeah, NASA budget, blah blah blah. I know, I really do. I wish NASA had the budget the Department of Defense currently enjoys and I wish we lived in a world where the DoD didn’t need a budget at all. We’ll get there, not tomorrow, but we’ll get there.
In the mean time, while space exploration isn’t as far along as space enthusiasts wish, exciting stuff is still happening. Specifically, one of the boldest missions NASA has ever attempted is about to reach its most nail-biting moment. First, you should sit down. Good. Now slide forward until you’re on the edge of your seat. No? Well, whatever.
Here’s the thing: A one-ton, nuclear powered, laser wielding, six-wheeled robot the size of a small car is going to land on Mars in less than a month. There. I said it. And I’m not making it up. This robot is called the Curiosity rover. Docile-sounding name? Yes. But here’s how I picture the rover:
Okay, now here’s what Curiosity really looks like (Curiosity is the 6-wheeled guy with the Wall-e head to the immediate right of two engineers having a picnic):
On Nov. 26, 2011, right around the time people on the East Coast of the U.S. were pouring their second cup of morning coffee, the Mars Science Laboratory launched from Cape Canaveral. When the craft arrives on Mars Aug. 6 it will have traveled 352 million miles.
The rover is powered by a Multi-Mission Radioisotope Thermoelectric Generator, or MMRTG (pronounced: muh-muh-ER-tig … just kidding). That loosely translates to “nuclear generator that runs on plutonium dioxide.” The rover really is equipped with a drill and a laser (see drawing above), as well as an arsenal of cameras, spectrometers, detectors and sensors. The purpose of Curiosity’s permanent visit to the Red Planet is to determine whether the planet ever had conditions capable of supporting microbial life. But that purpose only bears fruit if Curiosity survives its arrival at Mars.
The process through which Curiosity will land on Mars is laughably complex, and at the same time awe-inspiring. Here’s NASA’s sci-fi-style computer-generated animation of Curiosity, from when it enters the Martian atmosphere to when it touches down. Remember those charming touches of realism in the 2009 Star Trek film, or in the Firefly series, such as lens flare, zooming in and out, and a little bit of wobbly camera action? Yeah, they’ve got that:
Regardless, the Curiosity rover reaches Mars in less than a month. Maybe all the engineers’ calculations were solid and nothing goes wrong. Or, maybe something does go wrong. I’d prefer the former but will accept the latter. That a group of people planned and attempted such a complex project is good enough for me. Success or failure, we learn. If Curiosity does set foot on Mars and get on with the mission, hold your breath. It probably won’t find life or signs of life (I just have a feeling, or maybe I’m trying not to get my hopes up) but it will find something, probably something groundbreaking or Earth-shaking. This is science in action. Don’t miss it.
You can follow the Mars Science Laboratory on Twitter here and on Facebook here. Want to see where the space probe is now? Or would you like to see the countdown clock to Curiosity’s arrival on Mars? Click here. And set aside some time Aug. 6 to watch a little NASA TV. I imagine they’ll provide live coverage of the rover’s successful or unsuccessful landing here. I’ll be watching too, but my mind will be hundreds of millions of miles away.
