Centuries old shipwreck found at the bottom of the Gulf of Mexico

Here's a few great shots of an old copper-hulled ship that sank more than 200 years ago in the Gulf of Mexico. Among the artifacts are a canon, some plates and bottles, and several muskets.

From MSNBC:

A newly discovered 200-year-old shipwreck was found 200 miles off the Gulf Coast in more than 4,000 feet of water by the National Oceanic and Atmospheric Administration. The wooden hull of the ship has nearly disintegrated, but a greenish copper shell that once protected the ship's wood remains behind.

Not many details are available at the moment, but just imagine the story behind this incredible find!

Let's Build the Starship Enterprise!

I've said it before, and I'll say it again--we should fund a spaceship Kickstarter for a REAL spaceship. It's by no means a new idea, but someone has finally made a case for a workable plan.

The founder of the Build the Enterprise website, BTE Dan, says he's got an idea to build the starship Enterprise (or a reasonable version of it) to fly in actual outer space in 20 years.

Granted, there will be a few concessions (i.e., no warp speed) but he contends that the technology and know-how to construct an interplanetary space vessel exists--and we can do it in just two decades.

From the Build the Entperise FAQ:

Q: BTE-Dan, do you really think it’s technically possible to build the USS Enterprise over the next two decades?

A: Yes. It’s within our technological reach to build a full-sized Enterprise with 1g gravity. This Gen1 Enterprise can go on missions to key points of interest in our solar system, like Mars and Venus. It will be the biggest ship of any kind ever built by humans, and it will be larger than the tallest building in the world. It’s possible to build the Enterprise, and it would be a monumental achievement for us humans who inhabit the planet earth.

Q: How would building the Enterprise alter our manned space program?

A: The USS Enterprise from Star Trek is a cultural icon, and we should latch part of the US space program on to this icon and build from there. We need a far grander vision of what we should be doing to get humans up into space and how we might gain a permanent foothold there. If we aren’t going to get a sustainable presence up there, then we should stop spending money for putting humans into space and instead focus on robotic missions like sending more advanced rovers to Mars, Venus, and elsewhere. If we are going to ask taxpayers to pay billions of dollars for projects to put Americans into space, it should be for an idea that they can relate to and be inspired by. The general form and characteristics of the spaceship should be inspirational – and building the first generation of USS Enterprise would surely be inspirational.

Q: Well the ship is inspired by the Star Trek Enterprise, but it’s not the same. Please explain why it’s different.

A: It’s different because the technologies we have to work with in the first half of the 21st century are much different than the technologies that will exist in the 23rd century when Star Trek is set. We can only dream of what technologies may exist by then. So we can stay as true to the themes of the Enterprise ship as is possible given our technological limitations. We have to re-configure interior sections of the ship quite a bit. But it will still be a magnificently impressive ship. When completed, and given the missions that it will be capable of doing, it will be as inspirational as putting astronauts on the moon in 1969.

He makes a reasoned argument for realizing a spaceship, (I'll give him that!) though I think with it would likely take about twice that time to shake out any technical snafus along the way. Still, that's a mere fraction of the 2 and a 1/2 centuries that the Star Trek series postulates the possibility of the Enterprise. And really, who would give up cruising around the solar system in their own hot rod?

Here's a video of a proposed artificial gravity wheel to accomodate human habitation on long journeys. It's a neat solution that essentially turns the manned areas of the ship on it's side.



If only we could get an X Prize to build one of these!

Weirdest underwater lifeforms

Gizmodo's got a great video line-up of strange sealife they just posted. Here are two of my "favorites" (I guess?) for all-out weirdness. They'd make great aliens in some sci-fi story, no?

I agree with Gizmodo's assessemtnt that this Pacific Barrel-eyed Fish
looks like it has a tiny pilot inside.




This Predatory Tunicate looks like a giant cellophane Muppet.



Head on over for the full list. Fair warning: there's a definite lack of cuteness to some of these critters.

The Diversity of "Jellyfish"

I'm dusting off some old draft posts that I'd meant to put up earlier. This video "There's no such thing as a jellyfish" is a great primer on the critters. Plus its food for thought on a whole mess of topics, like life sciences, marine biology, and even astrobiology.

Also, it's breathtakingly gorgeous video!

Back at it

Has it really been almost a year between posts? Yikes! I didn't intend for that to happen, but life gets in the way I guess. Well, I'm working on a few posts to get back in the swing of things.

There may be a few new features/changes in store for ToA. I expect to make some cosmetic updates as well.

Stay tuned!

Martian test run in Austrian ice caves!

These amazing photographs are of a simulation experiment in ice caves located underneath Dachstein mountain in Austria that are serving as a test environment for space suits. Why would we need to test space suits in a cave? you ask. Well, so when we go to MARS we can see if perhaps life found a way to thrive underground.  

As you can see from these last two images, the trial also includes some rover robot testing. Pretty cool!

See caves are a great place for microbes to hang out because they benefit from a protected habitat that shields them from cosmic radiation, which is a known buzzkill when it comes to biology.

From Spiegal:

A dozen experiments are being conducted simultaneously in the caves. For example, the Magma Mars rover developed in Poland is navigating an ice surface. On board, it is carrying the Wisdom radar system, which is to be used on the next European Mars mission. The system can be used to analyze rocks at a depth of up to 3 meters (almost 10 feet). "Here in the ice, we can even examine as far as 10 meters deep," says project worker Stephen Clifford of the Lunar and Planetary Institute in Houston.

Without a doubt, though, the most spectacular test object is the "Aouda.X" Mars space suit. Tester Daniel Schildhammer is currently making his way in the space suit simulator through a giant cavern that is dotted with rocks. The shining silver suit, which weighs 45 kilograms (around 100 pounds), is also one of a kind, and is named after a Jules Verne character. In his classic novel "Around the World in 80 Days," the book's hero, Phileas Fogg, falls in love with the Indian princess Aouda.

Researcher Gernot Grömer, an astrophysicist at the University of Innsbruck goes on to talk about what makes caves ideal test environments.

"We've known for some time now that there are caves on Mars. And if there actually was life on its surface once, then they would have been the ideal places to retreat to." In astro-biological terms, there is certainly something to that: Cave systems, with their constant temperatures, elevated levels of humidity and, in particular, the protection they offer from cosmic radiation, seem the perfect refuge for simple life forms seeking a retreat. Still, the impressive images Dachstein has to offer were certainly a very pleasant side-effect for all the stakeholders.

Even got a little Jules Verne in there! Great stuff. Reminds me of another post a ways back.

This all is helping me close in on an idea I've had since that initial post on the crystal caves. Just amazing that we have these incredible images and research like this is actually being conducted. I'm in awe!
