Russia is working on a taxi to the moon

Posted by in category: space travel

A Russian rocket company has announced that it’s working on a space taxi that’ll shuttle crews from the ISS down to the moon. The plans were announced at an international conference on space exploration just outside Moscow and reported by Russia Today. The craft, provisionally named Ryvok, would be permanently docked on the ISS — or its replacement — transporting cargo and crews to the lunar surface. Each flight would be powered by fuel in an “accelerator block,” brought up from Earth on the back of a Russian rocket. The report explains that it’s likely to be the Angara A5, a heavy-lift vehicle that’s intended to replace the trusty old Soyuz.

Once it’s time to return to the ISS, the craft will blast off the moon for the five-day return journey. In order to slow its speed on approach, the ship will deploy a 55-square-meter “umbrella” that’ll reduce its speed like a parachute on a drag racer. At least, that’s the idea. The craft is expected to be developed by 2021, with the first launches anticipated to take place in 2023. The company is suggesting that its concept would be cheaper and faster to implement, since you don’t have to wait for the Angara rockets to be certified safe for human transportation.

If there’s one thing that’s given us pause, it’s the historical parallel between this Russian plan and Star Trek: Deep Space Nine. After all, things were relatively staid on the space station until the crew got their hands on the USS Defiant. After that point, the whole Federation suddenly found itself embroiled in a universe-wide war with a vastly superior enemy. There’s always a slight worry that, mere months after Ryvok docks at the ISS, that humanity, too, will find itself similarly overwhelmed.

Lasers Could Blast Astronauts to Mars, Protect Earth from Asteroids

Posted by in categories: innovation, space travel

The same laser system being developed to blast tiny spacecraft between the stars could also launch human missions to Mars, protect Earth from dangerous asteroids and help get rid of space junk, project leaders say.

Last month, famed physicist Stephen Hawking and other researchers announced Breakthrough Starshot, a $100 million project that aims to build prototype light-propelled “wafersats” that could reach the nearby Alpha Centauri star system just 20 years after launch.

The basic idea behind Breakthrough Starshot has been developed primarily by astrophysicist Philip Lubin of the University of California, Santa Barbara, who has twice received funding from the NASA Innovative Advanced Concepts (NIAC) program to develop the laser propulsion system.

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.

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.
