Saturn's tiny moon, Pan, was captured on March 7 during a flyby by NASA's Cassini spacecraft. The images captured during the flyby are the closest images ever taken of the moon which has an average diameter of only 17 miles.

Pan's prominent equatorial ridge gives it a distinctive flying saucer shape. The ridge is believed to be the result of material from Saturn's rings raining down on the moon.

Mars is approx. 12.5 light MINUTES away. It would take around 6 months to reach Mars with a manned aircraft. These 'new planets' are 40 light YEARS away. It would take around 800,000 years to reach these places by a manned aircraft....Don't you think we should quit with the nonsense fantasy and $20B/year spending for NASA?

 

100 years ago powered flight was a fantasy. Today air travel is so common EVERYONE does it. It used to take a year to sail around the world. Today you could legit circumnavigate the globe in two days - maybe one with good connection flights.

 

Do you really think we won't have technological breakthroughs that drastically cut travel time from here to other stars in the next century? How will that happen if we don't strive to advance technology?

 

To think of the sustainable water needed, vasts amounts of rich soil, perfect atmosphere in regards to chemical composition, shields of radiation, perfect gravitational pull, plate tectonics, constant weather that is able to be livable by all forms of life there is no chance there is a civilization that is in any way similar to ours.

I was in Salt Lake City on business a while back and decided to go to the Clark Planetarium and they had some extremely cool stuff.

 

This is a picture of a live feed they have. I have a couple short videos I took on my phone. The videos are kind of impressive, but do not even come close to doing justice to what the actual live feed looks like.

 

A look at the surface of our star, through a filtered telescope lens:

I want to know how they keep the rubber on the wheels from degrading during space flight. It's cold enough to rupture tires in space, and that thing has been in that icy coldness for two years, but it landed on its rubber wheels just fine.

 

It's clearly not the same material as we have on domestic car tires. Wonder what it's made of.

Tires are a black art. You can make them behave almost anyway you want by slightly tweaking the chemical compounds in the mixture, but you sacrifice other properties obviously. I've studied vehicle dynamics and some race engineering, and even those guys don't know what the hell tire engineers do half the time. That's arguably the most important part of a race car!

 

But really if there is no load on the tire its probably not going to crack. It's probably a couple steps up from a winter tire you get on your car.

I'm betting carbon nanotubes and non-gas filled, maybe some sort of foam.

Huh. You should go inform the folks at NASA that they've all been wasting their time and you've got it figured out.

 

I'm not saying that, but I think it is crazy to think that people find it fascinating without knowing the true reality of it. Over 5 years they spend over 100 BILLION DOLLARS. I would rather put that into something we know of - Earth.

 

And NASA's budget is still like .4% of the budget. It's not like they are getting a lot of money that could be used else where in the grand scheme of things.

 

$100B isn't a lot of money? I'll mark that one down

Hibernating Aliens May Explain Why We Haven't Found Any Other Life Yet

Scientists have proposed a rather interesting reason for why we haven’t found aliens yet, a problem known as the Fermi Paradox (if life is so abundant, where is everyone?). They propose intelligent aliens could be in a state of hibernation, waiting for the universe to get colder so they can be more productive.

This idea was proposed in the Journal of the British Interplanetary Society, with a pre-print available on arXiv. The paper was written by Anders Sandberg, Stuart Armstrong, and Milan Cirkovic of the Future of Humanity Institute at the University of Oxford, and picked up recently by Gizmodo.

Some people think that a civilization much more advanced than our own might become a digital race. That is to say, they’ll live as artificial intelligence inside computers, doing away with more limiting fleshy bodies. Experts including Elon Musk have suggested this is a logical progression in the far future.

If we are not alone in the universe (which we have no evidence for yet), one could therefore further propose that an advanced alien race might have gone down this route. But in order to make the most of their new digital bodies, they might not like the universe at the moment.

The temperature of the universe right now is 3 degrees Kelvin above absolute zero. That’s rather chilly, but that temperature will continue to drop as the universe expands. Sandberg and his colleagues argue that the temperature in the future could allow for 1030 more computational processes than are currently possible.

“We hence suggest the 'aestivation hypothesis',” the researchers write in their paper, adding that “the reason we are not observing manifestations of alien civilizations is that they are currently (mostly) inactive, patiently waiting for future cosmic eras.” Aestivation is basically hibernation to avoid hotter temperatures, not cooler ones.
