We can begin an interstellar mission today – and we should

Posted by in categories: particle physics, space travel

Fifty-five years ago, Yuri Gagarin rocketed into orbit and began to break our bonds to our planet. To mark the occasion, the nonprofit Breakthrough Institute just announced plans to free us from an even more formidable set of bonds and send a fleet of small spacecraft beyond our solar system, off to the stars. News of the ‘Breakthrough Starshot’ plan was met with great enthusiasm, but also with more than a little skepticism. The distance between stars is vast. Our closest neighbour, the Alpha Centauri system, is 4.4 light years away – roughly 25 trillion miles. The Voyager 1 spacecraft, the fastest object ever created by humans, would take 70,000 years to travel that far. Many reporters greeted the Breakthrough Starshot as an idea grounded more in fantasy than in reality.

The reaction was understandable. All previous plans for interstellar flight relied on non-existent or impractical technologies such as antimatter, wormholes and warp drives. But now we have a concrete path forward, which I have published in detail. It is possible to begin the journey to the stars today.

Drawing on recent advances in photonics and electronics, we could use arrays of lasers to accelerate miniature probes (the size and mass of a semiconductor wafer, weighing less than one ounce) to unprecedented velocities. Particles of light, or photons, have no rest mass but they carry energy and momentum. Just as a sailboat can be propelled by the wind, light sails can ride the momentum of photons by reflecting a wind of intense laser light. We call such focused beams of light ‘directed energy’.

Space exploration will spur transhumanism and mitigate existential risk

Posted by in categories: alien life, cyborgs, existential risks, geopolitics, policy, robotics/AI, solar power, space travel, sustainability, transhumanism

Friends have been asking me to write something on space exploration and my campaign policy on it, so here it is just out on TechCrunch:


When people think about rocket ships and space exploration, they often imagine traveling across the Milky Way, landing on mysterious planets and even meeting alien life forms.

In reality, humans’ drive to get off Planet Earth has led to tremendous technological advances in our mundane daily lives — ones we use right here at home on terra firma.

Why DARPA Is Pursuing the Reusable Military XS-1 Spaceplane

Posted by in categories: Elon Musk, government, military, space travel

Coming clean on the story around the XS-1 Spaceplane. Hmmm; US Government coming clean; really?


ORLANDO, Fla. – Here’s a phrase that’s not repeated everyday in the space community:

“You’ve heard Elon’s comments … we want to go beyond that,” Brad Tousley, the head of the tactical technology office at the Defense Advanced Research Projects Agency, said May 15.

Gorgeous Animation Shows a Spaceship Mysteriously Traveling to a Universe Beyond

Posted by in category: space travel

Absolutely beautiful animation.

Where do I sign up to be ON one of those?! wink


I want to know more about the world in this short animation Entropy, by Tim Cahn. I want to know why the spaceship is leaving Earth. I want to know what the space station is doing all the way out there. I want to know who’s there. I want to know where the ship is headed. I want to live in this world. But in the stillness of the short, we only get to see the beautiful imagery of a spaceship leaving Earth, so we have to fill in the blanks ourselves.
