Towards an Economically Viable roadmap to large scale space colonization

Posted by in categories: energy, space

Al Globus and Joe Strout have an analysis that space settlements in low (~500 km) Earth equatorial orbits may not require any radiation shielding at all. This is based on a careful analysis of requirements and extensive simulation of radiation effects. This radically reduces system mass and has profound implications for space settlement, as extraterrestrial mining and manufacturing are no longer on the critical path to the first settlements, although they will be essential in later stages. It also means the first settlements can evolve from space stations, hotels, and retirement communities in relatively small steps.

This huge reduction in total mass compensates for the greater energetic difficulty of launching materials from Earth to ELEO as opposed to launching from the Moon to L5, the design location of the Stanford Torus. In the early studies, the Earth­Moon L5 point was chosen as the location of a settlement for the energetic advantage of launching materials from the Moon. Going from the Moon to L5 requires a delta­-v 3 of 2.3 km/sec, and going from Earth to 500 km ELEO is 10 km/sec [Cassell 2015]. Using the velocity squared as our energy measure, Earth to ELEO requires 19 times more energy per unit mass. Analysis suggests that at least 19 times less mass is needed if no radiation shielding is required. Thus, the energetic advantage to launching the mass of a settlement with deep space radiation shielding from the Moon to L5 is balanced by launching far less mass from Earth if no radiation shielding is necessary.

A 500 km circular ELEO using polyethylene shielding was analyzed. Even at 10 kg/m2 shielding, the equivalent of which is very likely to be provided by any reasonable hull, the 20 mSv/yr and 6.6 mGy/yr are met. Indeed, with no shielding at all the general population limit is met and the pregnancy limit is very nearly met. This has an interesting consequence: spacewalks in ELEO may be safe enough from a radiation point of view to be a significant recreational activity.

Moon as unprospected eighth continent that will produce trillionaires

Posted by in categories: futurism, space travel

Moon Express is one of only two teams in the Google Lunar XPRIZE competition with a verified launch contract for its 2017 lunar mission. In October 2015, Moon Express announced that it had signed the worlds’ first multi-mission launch contract with Rocket Lab USA for 3 lunar missions between 2017 and 2020.

Moon Express sees the moon as critical for humanity to become a multi-world species, and that our sister world, the Moon, is an eighth continent holding vast resources than can help us enrich and secure our future.

MoonEx had been planning to place the International Lunar Observatory (ILO) on the Moon as early as 2018. The plan calls for placement of both a 2 meters (6 ft 7 in) radio telescope as well as an optical telescope at the South Pole of the Moon.

Scientists Have Set a Limit For Quantum Entanglement — And It’s Really Freaking Powerful

Posted by in categories: particle physics, quantum physics

For the first time, scientists have subjected quantum entanglement to extreme levels of acceleration, and there’s nothing fragile about this “spooky action at a distance” - it’s way more robust than we thought.

In recent experiments, entangled particles held firm even while being accelerated to 30g — 30 times Earth’s acceleration — and the results could have a big impact on our search for a unified theory of modern physics.

“These experiments shall help [us] unify the theories of quantum mechanics and relativity,” says one of the team, Rupert Ursin, from the University of Vienna, Austria.

NYU Accidentally Leaked a Top-Secret Code-Breaking Supercomputer to The Entire Internet

Posted by in categories: cybercrime/malcode, encryption, internet, supercomputing

Confidential details of a top-secret encryption-breaking supercomputer were left completely exposed on an unsecured computer server belonging to New York University (NYU), according to a new report.

While it’s not uncommon for even critical-level infrastructure to suffer potentially catastrophic security breaches, what makes this event different is that there was seemingly no foul-play or attempts to hack into NYU’s systems.

Instead, it looks like somebody may have just forgotten to secure their classified data properly, exposing hundreds of pages of information on a covert code-breaking machine co-administered by the Department of Defence, IBM, and NYU.

Vivid Vision raises $2.2 million to build VR tools to treat ‘lazy eye’

Posted by in category: virtual reality

Startup Vivid Vision said today it has raised $2.2 million in a seed round to build VR tools that could be used to treat eye problems known as “lazy eye.”

San Francisco-based Vivid Vision raised the money from SoftTech VC’s Jeff Clavier, as well as The Venture Reality Fund (The VR Fund), CRCM Ventures, SOS Ventures, Anorak Ventures, and Liquid 2 Ventures, a seed-stage venture capital firm cofounded by Hall of Fame NFL quarterback Joe Montana.

The company’s VR treatment for binocular vision disorders is now available at more than 90 clinics across the world. More than 10 percent of Americans suffer from one or more binocular vision disorders, such as amblyopia, strabismus, or convergence insufficiency. These disorders, commonly known as “lazy eye” and “crossed eyes,” can cause issues with driving and playing sports, and can even limit career choices.
