Quoted: Since the rover is already on Mars and it’s solar powered why does it cost $4 million a year to operate? I’m not doubting it does I just don’t know how projects like this work. Is most of it tied up in the salaries of the scientists working on the project, the computer systems used to analyze the data, or what?

Awesome. We now know the age of the universe with pretty good accuracy.

Great talk

Quoted: TED Talks Legendary physicis David Deutschback-burners the work for which he&#39;s best known -- quantum physics, quantum computing, the many-worlds theory -- to discuss a more basic topic: how to think about our species significance in the universe. Far from being simply &quot;chemical scum,&quot; we have the ability to gain knowledge, the importance of which he illustrates in spectacular manner. As a result, he says, we are always equipped to solve problems (including global warming). The brain contains the tools we need: <strong>knowledge, reason and creativity</strong>. It&#39;s a thrilling, and profoundly optimistic argument.

Quoted: During the multi-million year assembly period, massive hoses would worm deep into the Earth's fiery bowels and suck liquid metal and magma into orbit through four space elevators sited at equal distances around the equator. This material would be squirted out and transformed into a lattice framework to support the rest of the edifice.

I want to go to space...

Quoted: "Oh right... we needed to repair that space station. Kinda forgot about that."

amazingly smooth

Quoted: The Japan Aerospace Exploration Agency (JAXA) and public broadcaster NHK have succeeded in capturing the world’s first high-definition video of the moon taken from lunar orbit.

Quoted: TED Talks <a href="/speakers/view/id/129" target="_blank">Stephen Petranek</a> reveals the question that occupies scientists at the end of the day (and the beginning of happy hour): How might the world end? He lays out the challenges that face us in the drive to preserve the human race. Will we be wiped out by an asteroid? Eco-collapse? How about a particle accelerator gone wild?

Quoted: Scientists have discovered a warm and rocky "second Earth" circling a star, a find they believe dramatically boosts the prospects that we are not alone.

Quoted: An MIT-led team of planetary scientists has found that the southern pole of Mars contains the largest deposit of frozen water in the inner solar system, outside of Earth.
