If There’s Life on Europa, Robots Like These Will Find It

Posted by in categories: robotics/AI, space travel

The exploration of Europa begins under the ice in Antarctica.

That’s where a team of researchers, led by the Georgia Institute of Technology (Georgia Tech), has been testing a variety of robotic subs in recent years to learn about what technologies will work best when NASA eventually launches a mission to Jupiter’s icy moon.

Tech billionaire Elon Musk is convinced that we must colonise Mars with a million people if the humanity is to survive long-term. To that effect in 2008, he almost went broke funding SpaceX – his then-new aerospace company – to keep developing next-generation rockets.

And on Tuesday, at a challenging moment in the 14-year-old company’s history, Musk plans to unveil his grand vision: to turn Mars into a “backup drive” and save humanity.

Making rocket fuel from water could drive a power revolution on Earth

Posted by in category: space travel

Researchers led by NASA’s former chief technologist are hoping to launch a satellite carrying water as the source of its fuel.

The team from Cornell University, guided by Mason Peck, want their device to become the first shoebox-sized ‘CubeSat’ to orbit the Moon, while demonstrating the potential of water as a source of spacecraft fuel.

It’s a safe, stable substance that’s relatively common even in space, but could also find greater use here on Earth as we search for alternatives to fossil fuels.

Robert Zubrin’s Nuclear Salt Water Rocket Design

Posted by in category: space travel

Robert Zubrin is best known for his advocacy of the manned exploration of Mars.

Zubrin also had a design for interplanetary propulsion called the Nuclear Salt Water Rocket.

A nuclear salt-water rocket (NSWR) is a theoretical type of nuclear thermal rocket. A conservative design for the rocket would be fueled by salts of 20 percent enriched uranium or plutonium. The solution would be contained in a bundle of pipes coated in boron carbide (for its properties of neutron absorption). Through a combination of the coating and space between the pipes, the contents would not reach critical mass until the solution is pumped into a reaction chamber, thus reaching a critical mass, and being expelled through a nozzle to generate thrust.

Challenge Accept Peter

Posted by in categories: Peter Diamandis, space travel

What would happen in the world if we could find renegade thinkers, give them the right dose of inspiration, and reinforce the audacity, passion and perseverance needed to pursue their biggest ideas?

How to Make a Spaceship is exactly the inspiration the next generation of audacious thinkers needs. (For more on the book, click through these tabs!)

As author Julian Guthrie said, “I hope this story is an inspiration. I hope that when you get to the end of this story, you set down the book and feel like you can go out and do something impossible in your own life.”

Lawrence Krauss Versus Freeman Dyson on Gravitons

Posted by in categories: alien life, engineering, genetics, particle physics, quantum physics, robotics/AI, space travel

Yesterday, in the New York Review of Books, Freeman Dyson analyzed a trio of recent books on humanity’s future in the larger cosmos. They were How to Make a Spaceship: A Band of Renegades, an Epic Space Race, and the Birth of Private Spaceflight; Beyond Earth: Our Path to a New Home in the Planets; and All These Worlds Are Yours: The Scientific Search for Alien Life.

Dyson is “a brilliant physicist and contrarian,” as the theoretical astrophysicist Lawrence Krauss recently told Nautilus. So I was waiting, as I read his review, to come across his profound and provocative pronouncement about these books, and it came soon enough: “None of them looks at space as a transforming force in the destiny of our species,” he writes. The books are limited in scope by looking at the future of space as a problem of engineering. Dyson has a grander vision. Future humans can seed remote environments with genetic instructions for countless new species. “The purpose is no longer to explore space with unmanned or manned missions, but to expand the domain of life from one small planet to the universe.”

Dyson can be just as final in his opinions on the destiny of scientific investigation. According to Krauss, Dyson once told him, “There’s no way we’re ever going to measure gravitons”—the supposed quantum particles underlying gravitational forces—“because there’s no terrestrial experiment that could ever measure a single graviton.” Dyson told Krauss that, in order to measure one, “you’d have to make the experiment so massive that it would actually collapse to form a black hole before you could make the measurement.” So, Dyson concluded, “There’s no way that we’ll know whether gravity is a quantum theory.”
