The ESA's Rosetta comet orbiter has found complex, solid organic molecules in dust particles that came of the comet 67P/Churyumov-Gerasimenko, lending credence to the theory that organic compounds, or even life itself came from the stars.

As a second step I'd love to see it happen. At the same time I have my doubts. Putting a man on the moon cost $20B in 1960s dollars. While this is clearly just the first installment, getting to Mars is going to take that much money every year until we get there, and I'm not sure the determination is quite to that point yet. Priorities change all the time. Apollo happened at a time when you could organize an enormous concerted national effort. I don't think we have that spirit right now. In 1961 the presidents says "I've decided we're going to the moon," and people stop discussing the merits and start discussing the practicalities. If Obama asked me to pick up a Snicker's wrapper off the ground, depending on the tone of his voice I might well tell him to go fuck his mother. Without the existential threat that Sputnik represented and the attitude sitcktogetherness that the cold war brought, I just can't see us completing such a thing.

Consider that most of that $19B will probably be spent just in the planning stage. It'll be a year or two before anything is actually done, and that's time where people can change their mind tax-free, so to speak.

On the flip, and less cynical side, It's nice to see this bill getting bipartisan support. Space exploration is valuable far, far beyond the exploration of space.
Argument, the presentation of reasonable views, never makes headway against conviction, and conviction takes no part in argument because it knows.

Sounds awesome. Hopefully they can actually pull it off.

At this point though I really don't care who gets to Mars first just as long as someone actually does and soon.

I really don't think this can be overstated.  This was a rare alignment of history, politics and culture coming together to make this happen.  I don't doubt that if that trajectory had been continued, we would have humans on Mars 10 or 20 or more years ago.  Technology is rarely if ever the limiting factor.

Quote from: Elon Musk about going to Mars

"Ultimately, I'd suspect you'd see Mars transit times of as little as 30 days in the distant future," he said, noting it's a lot different than the estimates of six months or more that are often passed around.

"During the journey, he wants to set up the spaceship's crew compartment so that passengers can play zero-gravity games, watch movies, and more."

"It will be, like, really fun to go," Musk said. "You'll have a great time."

Very exciting.  They need to send something there immediately.

This is much more convincing than the first set of Hubble observations. Hopefully it'll boost/maintain funding for the Europa Clipper mission.

Speaking of Hubble, the building of it's substitue the James Webb telescope is apparently done and will be launched in 2018. Can't wait to see what mystery of the universe it will unfold. Ultra Deep Field ×10 perhaps.

20 years of build time, hopefully it won't blow up at launch, that would be a bit salty for the engineers. :lol

I just stumbled across this great video about nVidia using computer graphics to debunk moon landing hoax arguments about photos taken on the moon. Even if you don't know CGI or lighting, it's well worth skimming to gain some understanding of the principles involved.

It's cool but again, whenever they discover new exoplanets which seems to be all the time I can't help but feel a bit meh when I know we will never get there in our lifetime. The discovery itself is still amazing. I think when the James Webb telescope is operational stuff will get even more interesting.

Still cool though. I'm sure Galileo wasn't thinking of something like Cassini when he was observing Saturn through his telescope. We're laying down the pavement for future generations. I dig it.

I read when the news broke about the latest exoplanets, that scientists believe we'll be able to know if there's life on any of those worlds in about a decade or so. I'm not sure about that however -- I mean, we still can't confirm if there is life anywhere in our solar system yet, much less something light years away.

I hope they can do it, however. It was an exciting discovery. Those who follow it more closely -- am I accurately recalling that, in addition to the fact that the planets are so close together, that gravity impacts all of them from each other, that only one side of them faces the star?

Yes, they are all tidally-locked to the star, so only one side faces the light from the star at any point. This means that each side of the respective planet either always has day or always has light.

Thanks for confirming for me. Interesting. Obviously, the possibility for life in that situation exists, but man, I wonder just how different it may be. Good stuff for some science fiction writing too.

If there are oceans of water and assuming organisms consume one another for energy, I think it is likely we will see creatures very similar to the fish on Earth, at least in regards to their shape. Granted we have some creatures like the octopus and jellyfish that don't fit the mold, but the bulk of sea life shares the torpedo shape. This wasn't due to evolutionary chance, it was due to physics. We've seen fish and mammals from independent evolutionary lines arrive at the same shape (sharks and dolphins) because of evolution's drive for efficiency. If you need to move through water fast for survival, the torpedo is the shape, and if you need to steer, fins are easy to make and light weight relative to the body.

Its interesting to me that we can make some assumptions about alien life that are reasonable, which are based on physics rather than the specific conditions on earth.  Even though our imaginations are limited to life on earth, the universality of physics places some limits on forms life can take in the universe.

Remarkably, the constraints of environment on physical bodies also constrain life to be roughly the same size that intelligence requires. The height of the tallest redwoods is limited by their inability to pump water more than 100 meters into the sky, a limit set by a combination of the force of gravity on the Earth (which pulls the water down) and transpiration, water adhesion, and surface tension in the plant xylem (which pushes it up).
