Another reliable article on the Quantum Internet work.

You can’t sign up for the quantum internet just yet, but researchers have reported a major experimental milestone towards building a global quantum network — and it’s happening in space.

With a network that carries information in the properties of single particles, you can create secure keys for secret messaging and potentially connect powerful quantum computers in the future. But scientists think you will need equipment in space to get global reach.

Researchers from the National University of Singapore (NUS) and the University of Strathclyde, UK, have become the first to test in orbit technology for satellite-based quantum network nodes.

A quantum node device that might pave the way for a future space-based quantum Internet has been successfully tested for the first time aboard a small satellite.

The device, called SPEQS, has been developed by a team from the National University of Singapore (NUS) and the Glasgow-based University of Strathclyde. It contains technology for creation of the so-called correlated photons, which are a precursor for the better known entangled photons that communicate across large distances.

In an article published in the latest issue of the journal Physical Review Applied, the team led by NUS researcher Alexander Ling described first result of the experiment, which saw the SPEQS system reliably creating and measuring pairs of photons with correlated properties.

Also, here is Eros compared to Lake Tahoe:

And I have to mention though I cannot find the proper link, there is at least one burnt out comet head that is a Near Earth body who’s water content has been compared to Lake Tahoe.

NASA’s Asteroid Redirect Mission has had its funding cut. Here’s why politicians should think again.

With 3D printers (like the one in India) printing buildings while leveraging AI technology we could see the building of complexes in space v. needing an inflatable room.

NASA on Saturday successfully expanded and pressurized an add-on room at the International Space Station two days after aborting the first attempt when it ran into problems.

The flexible habitat, known as the Bigelow Expandable Activity Module (BEAM), completed slowly extending 67 inches (170 centimeters) at 4:10 pm (2010 GMT) following more than seven hours during which astronaut Jeff Williams released short blasts of air into the pod’s walls from the orbiting lab using a manual valve.

After the expansion was completed, he opened eight air tanks inside BEAM, pressurizing the pod to a level close to the space station’s 14.7 pounds per square inch.

The International Space Station grew in size on Saturday when the Bigelow Expandable Module (BEAM) was successfully expanded on the second attempt after the initial deployment on Thursday did not work out as planned.

Putting in a long weekend shift, teams at Mission Control and Astronaut Jeff Williams worked for close to eight hours to finally accomplish a safe expansion & pressurization of the module.

BEAM’s expansion marks the conclusion of a two-decade effort between NASA and private industry to test out expandable habitat technology in space.

Watch this fantastic futuristic short film directed by talented Collin Davis and Matt Litwiller, written by Eric Bodge and shot by Travis Labella! The year is 2183. Earth is dead. With all evidence of organic life lost, a cosmic archaeologist travels faster than light into deep space to capture images of the once vibrant planet. When his vessel is damaged he must take matters into his own hands, risking his life to witness humanity’s lost home.

Physics can be pretty intense at times, but one of the most straightforward aspects is that everything in the Universe is controlled by just four fundamental forces: gravity, electromagnetic, and strong and weak nuclear forces.

But now physicists in Hungary think they might have found evidence of a mysterious fifth force of nature. And, if verified, it would mean we’d need to rethink our understanding of how the Universe actually works.

Before we get into that, let’s go back to those four forces for a second, because they’re pretty important. They’re a fundamental part of the standard model of physics, which explain all the behaviour and particles we see in the Universe.

A more efficient way to mine water and other chemical volatiles to create rocket fuel in situ is arguably the fastest way to colonize the Moon and Mars.

Despite the recent buzz about eventually mining asteroids for metals, their real near-term value may be as space-based sources of water and carbon dioxide from which to make rocket propellant. The trick is in mining such volatile compounds efficiently enough to convert them to fuel in situ. That is, without having to import such resources from gravitationally-bound, planetary surfaces like the Moon, Mars or even Earth.

Here’s where a potentially revolutionary patent pending process dubbed “Optical-Mining” would figure in. The idea is to use this new technology to excavate both water ices and other volatile compounds from small 10 meter-diameter Near-Earth Asteroids. If successful, such an In Situ Resource Utilization (ISRU) asteroid-mining operation could mark the tipping point in viably extracting resources from thousands of such asteroids.
