​Inside a Billionaire’s New Interstellar Mission

Posted by in categories: futurism, space travel

Yuri Milner is spending $100 million on a probe that could travel to Alpha Centauri within a generation—and he’s recruited Mark Zuckerberg and Stephen Hawking to help. In an interview with The Atlantic, Milner makes his case for star travel.

In the Southern Hemisphere’s sky, there is a constellation, a centaur holding a spear, its legs raised in mid-gallop. The creature’s front hoof is marked by a star that has long hypnotized humanity, with its brightness, and more recently, its proximity.

Since the dawn of written culture, at least, humans have dreamt of star travel. As the nearest star system to Earth, Alpha Centauri is the most natural subject of these dreams. To a certain cast of mind, the star seems destined to figure prominently in our future.

Billionaire pledges $100m to send spaceships to Alpha Centauri

Posted by in category: space travel

Regardless of whether or not this particular project achieves it’s aims, hopefully it will encourage other obscenely wealthy philanthropists to funnel their donations into private (or governmental ) outer-space related endeavors!


Yuri Milner has backed a plan to research sending tiny, laser-powered spacecraft to the nearest star at 20 per cent of the speed of light.

How Self-Replicating Spacecraft Could Take Over the Galaxy

Posted by in categories: alien life, robotics/AI, space travel

Forget about generation ships, suspended animation, or the sudden appearance of a worm hole. The most likely way for aliens to visit us — whatever their motive — is by sending robotic probes. Here’s how swarms of self-replicating spacecraft could someday rule the galaxy.

Back in late 1940’s the Hungarian mathematician John Von Neumann wondered if it might be possible to design a non-biological system that could replicate itself in a cellular automata environment, what he called a universal constructor. Von Neumann wasn’t thinking about space exploration at the time, but other thinkers like Freeman Dyson, Eric Drexler, Ralph Merkle, and Robert Freitas later took his idea and applied it to exactly that.

NASA Begins Testing of Revolutionary E-Sail Technology

Posted by in category: space travel

Testing has started at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on a concept for a potentially revolutionary propulsion system that could send spacecraft to the edge of our solar system, the heliopause, faster than ever before.

The test results will provide modeling data for the Heliopause Electrostatic Rapid Transit System (HERTS). The proposed HERTS E-Sail concept, a propellant-less propulsion system, would harness solar wind to travel into interstellar space.

“The sun releases protons and electrons into the solar wind at very high speeds — 400 to 750 kilometers per second,” said Bruce Wiegmann an engineer in Marshall’s Advanced Concepts Office and the principal investigator for the HERTS E-Sail. “The E-Sail would use these protons to propel the spacecraft.”

Reconstituting Asteroids into Mechanical Automata

Posted by in categories: computing, robotics/AI, space travel

The objective of this study is for Made In Space (MIS) to establish the concept feasibility of using the age-old technique of analog computers and mechanisms to convert entire asteroids into enormous autonomous mechanical spacecraft. Project RAMA, Reconstituting Asteroids into Mechanical Automata, has been designed to leverage the advancing trends of additive manufacturing (AM) and in-situ resource utilization (ISRU) to enable asteroid rendezvous missions in which a set of technically simple robotic processes convert asteroid elements into very basic versions of spacecraft subsystems (GNC, Propulsion, Avionics). Upon completion, the asteroid will be a programmed mechanical automata carrying out a given mission objective; such as relocation to an Earth-Moon libration point for human rendezvous or perhaps to set an Earth-threatening NEO on course to the outer solar system and out of harm’s way. This technique will create an affordable and scalable way for NASA to achieve future roadmap items for both the Human Exploration and Operations Mission Directorate (HEOMD) and the Science Mission Directorate (SMD) such as Asteroid Redirect Mission (ARM), New Frontiers Comet Surface Sample Return, and other Near Earth Object (NEO) applications. It is estimated that an order of magnitude increase in NEO targets can be explored for the same mission cost with the RAMA approach compared to the SOA Asteroid Redirect Mission (ARM) architecture by removing the need to launch all spacecraft subsystems and instead converting the asteroid into them in-situ. Assuming the development trends continue for industry based AM methods as well as NASA and industry investments in ISRU capabilities, Project RAMA will create a space mission architecture capable of achieving the aforementioned NASA goals within a 20–30 year time frame. Furthermore, as described in the proposal, the identified study path will provide insight into near term Mission ‘Pull’ technologies worth investment in order to create the development roadmap for the proposed ‘Push’ technologies for achieving NASA’s long term strategic goals.

SpaceX reusable stages, drone ship technology and the SpaceX Heavy

Initially SpaceX plans to reduce the cost of a Falcon 9 rocket with a reused booster to $43 million per flight, a savings of 30 percent.

SpaceX will try to return the booster that was just landed on the drone ship back to Cape Canaveral, in Florida, by Sunday. After running a series of tests on the Falcon, the company plans to fire its engines 10 times in a row on the ground. “If things look good it will be qualified for reuse,” Musk said. “We’re hoping to relaunch it on an orbital mission, let’s say by June.”

With Mars in Mind, Lockheed Martin Designs Human Habitat to Orbit Moon

Posted by in categories: computing, habitats, health, space travel

A major concerned for Lockheed is the long passage of time between the crew’s training and the moment a serious issue does come up during a mission—which could be a few years later. “They may not remember the training. Having the right kind of on-board documentation and flight computer to be able to provide the astronauts the information they need when they need it, is important,” Pratt said. “Not just having the alarm go off but having the alarm go off and the PDF file of the manual come up at the same time. That’s really useful in helping the crew understand how to operate their own vehicle.”

Even though Lockheed Martin’s early habitat concept will service exploration missions near the Moon, the company is always thinking about the manned mission to Mars, which will require a far more advanced successor to their current designs. Engineers will need to go through a few iterations of the concept after the health effects of long-duration human spaceflight are known and as new technology is developed. This is the basis that NASA created NextSTEP on.

The federal space agency is looking for a modular habitat that can grow, evolve and be added to. “New modules are built upon the lessons of the previous modules,” Hopkins said.

SpaceX delivers world’s first inflatable room for astronauts

Posted by in categories: robotics/AI, space travel

SpaceX has made good on a high-priority delivery: the world’s first inflatable room for astronauts.

A SpaceX Dragon cargo ship arrived at the International Space Station on Sunday, two days after launching from Cape Canaveral. Station astronauts used a robot arm to capture the Dragon, orbiting 250 miles (400 kilometers) above Earth.

The Dragon holds 7,000 pounds (3,175 kilograms) of freight, including the soft-sided compartment built by Bigelow Aerospace. The pioneering pod—packed tightly for launch—should swell to the size of a small bedroom once filled with air next month.
