Comment Foil coverings (Score 2) 87

I noticed the wheels are covered with foil and the retro-thrusters look like they have giant rubber stoppers in them. Does anyone know the purpose of these? I am assuming the stopper things would be launched out when they're fired but how does the foil come off the wheels once at Mars? (or is that just a protective covering for until the thing is fully loaded and ready to be launched into space?)

Comment Re:Independence (Score 2) 263

As far as I can tell, we're hard-wired to derive pleasure from independence and self-reliance, probably because it's an advantageous trait in evolutionary terms.

Although this is exactly how I feel about myself, I've mostly found the complete opposite of most people. It probably depends on the person and the situation though. My parents are super DIY'ers for home repairs/improvements but when it comes to technology they just flat out refuse to learn how to do things themselves. They'd rather rely on me to "just fix it."

Comment Sources of error? (Score 1) 1088

Article says they eliminated possible sources for error but doesn't list them. Every scientific paper I've ever wrote had a section you had to list possible venues for errors in your experiment. I don't doubt they did, but I'd like to know what they were. I can't even get all my clocks in my apt to sync up to my computer or at work or to the tv or anything else. I imagine it's really hard to do this with two remote locations unless the clocks were perfectly synced in person and then transported to the different research stations. Otherwise, if they eliminated all possible known error sources could this have been a spacetime bend? We already know that matter/gravity bends spacetime. Perhaps there was a varying gravity density between the two stations? I know neutrinos rarely interact with matter but are they affected by gravity like photons are?

Comment Before the obvious... (Score 1) 116

I know there will be a few "who cares?" and "why are we bothering?"... If it's in orbit it will come back around again. Much like how we need to track all satellites around Earth to prevent collisions, and asteroids/comets that may be on a trajectory towards Earth, we'll need to track this object as well. Who knows when and where it might collide with something in the future.

Comment Right... (Score 1) 82

Which is why you don't test the soil for microbes right where the lander put its wheels... The entire rest of the planet is still a viable target for research. Anything that isn't buried beneath the regolith pushed by the wheels will die from UV exposure. Blown away/exposed by wind? UV exposure. This is seriously a non-threat. As long as you don't sample from wheel treads and the rover was properly sterilized it'll be fine. (not to mention any microbes you find should be tested in comparison to those of earth origin. It's highly unlikely that you'll find an identical strain of organism on Mars as found on Earth.)
