Affordable deep space missions using asteroids
Posted by Klaus Baldauf in categories: government, mathematics, physics, space
Phase 1 work demonstrated Optical Mining in the laboratory and performed mission and systems analysis of the application of Optical Mining to human exploration missions. Their mission analysis showed that the most accessible Near Earth Objects (NEOs) can be used to provide NASA with mission consumables for human exploration in deep space with the potential of saving up to $10 billion per year or $150 billion over the 15 year operational life cycle of a human exploration program. This savings alone would be enough to transform NASA’s vision of human exploration from being unaffordable to being affordable within budgets that Congress can approve. Phase 1 technical work included a full scale (8 kW) Optical Mining demonstration using a high fidelity CI-type asteroid simulant in vacuum using sunlight from a 10 meter diameter solar concentrator without mechanical contact or downforce. This work confirmed our physics based mathematical model of the excavation and volatile extraction process and scalability of results from 36 prior, small scale (≈ 1 cm diameter) demonstrations and tests.
Phase 2 work will complete mission and system analysis of the application of Optical Mining to an exciting program of human exploration and we will mature the technology of Optical Mining to the point at which NASA can baseline this approach for an affordable program of human exploration. Our mission studies will address the production via Optical Mining missions to extract and retrieve resources, consumable processing, storage, and application of consumables to human exploration mission in cislunar, NEO and Martian space. The mission studies will be tightly coupled with our laboratory work. Laboratory work will include the development and integration of a 30 kW Optical Mining test apparatus in our laboratory and integration with our high quality vacuum chamber for a test program involving Optical Mining.

Solar-powered device turns air into drinkable water
Posted by Simon Waslander in categories: space, sustainability
Scientists literally pulled this out of thin air.
Engineers at MIT and the University of California Berkeley have designed a system, powered by sunlight, that can turn air into liters of drinkable water.
This box has the potential to help drought-stricken communities, desert explorers or — someday — astronauts traveling to dry, dusty planets. The report was a href=” http://science.sciencemag.org/content/early/2017/04/12/science.aam8743” target=”_blank”

Watch Russian space-bound FEDOR robot fire dual-wielding pistols

The two fundamental prerequisites for large-scale economic use of space resources are:
1. in-space manufacture of propellants from nonterrestrial bodies, and 2. in-space manufacture of heat shields for low-cost capture of materials into Earth orbit.
The former has been the subject of recent NIAC investigations. The latter would expand by a factor of 30 to 100 time the number of asteroids from which resources could be returned cost-effectively to Earth orbit. With vastly larger populations from which to choose, return opportunities will be much more frequent and targets can be selected where operations would be highly productive, not merely sufficient. The feedstocks for manufacture of life-support materials and propellants are found on C-type near-Earth asteroids, which have high concentrations of hydrogen, carbon, nitrogen, oxygen and sulfur. The total abundance of readily extractable (HCNOS) volatiles in the CI chondritic meteorite parent bodies (C asteroids) is roughly 40% of the total meteorite mass. Further, the residue from extraction of volatiles includes a mix of metallic iron (10% of total mass), iron oxide and iron sulphides (20% as Fe) plus 1% Ni and ~0.1% Co.

Entrance to Mars: How this fascinating Dome-Space-Elevator grows in all directions
Posted by Klaus Baldauf in categories: engineering, environmental, space, sustainability
Architecture has evolved and has become much more than just a design realized in concrete and modern building material. It has been transformed to help humanity in achieving all kinds of sustainability.
The eVolo Magazine for Architecture has been organizing another round of Skyscraper Competition in 2017 to honor those visionaries that try to realize a future that benefits humanity and the one Earth we all need to cherish and sustain.
A team from Spain with aspiring architects Arturo Emilio Garrido Ontiveros, Andrés Pastrana Bonillo, Judit Pinach Martí and Alex Tintea is thinking of a hybrid solution, that ensures Humanity’s survival in the early days of Mars’ colonization. The skyscraper design is both clever and beautiful, combining existing technologies with many practical ideas to open up and terraform more red soil as we understand the planet. It’s a genesis of Mars and a revival of form following function.

NASA: Nearby ocean worlds could be best bet for life beyond Earth
Posted by Sean Brazell in category: space
Fascinating stuff!
NASA has new evidence that the most likely places to find life beyond Earth are Jupiter’s moon Europa or Saturn’s moon Enceladus. In terms of potential habitability, Enceladus particularly has almost all of the key ingredients for life as we know it, researchers said.
New observations of these active ocean worlds in our solar system have been captured by two NASA missions and were presented in two separate studies in an announcement at NASA HQ in Washington today.

NASA Cuts A Huge Check To Underwrite Asteroid Mining
Posted by Klaus Baldauf in categories: materials, space
NASA awarded $125,000 to a mining company to develop technology to extract minerals embedded in asteroids.
NASA will pay Deep Space Industries (DSI) for technology to return mined minerals from asteroids to Earth’s orbit. DSI is developing a way to use aerobraking to bring minerals back to Earth.
DSI said the grant will support the company’s research into creating aerobrakes out of materials found on near-Earth asteroids.

Second ‘Great Spot’ found at Jupiter, cold and high up
Posted by Dan Kummer in category: space
CAPE CANAVERAL, Fla. (AP) — Another “Great Spot” has been found at Jupiter, this one cold and high up.
Scientists reported Tuesday that the dark expanse is 15,000 miles (24,000 kilometers) across and 7,500 miles (12,000 kilometers) wide. It’s in the upper atmosphere and much cooler than the hot surroundings, thus the name Great Cold Spot. And unlike the giant planet’s familiar Great Red Spot, this newly discovered weather system is continually changing in shape and size. It’s formed by the energy from Jupiter’s polar auroras.
A British-led team used a telescope in Chile to chart the temperature and density of Jupiter’s atmosphere. When the researchers compared the data with thousands of images taken in years past by a telescope in Hawaii, the Great Cold Spot stood out. It could be thousands of years old.
