NASA wants to build giant spacecraft with 3D printing spiders

Right now it's easy to think of NASA's glory days as being behind it. China and Europe are sending rockets to space stations, private industry is creating space tourism and NASA's space shuttle program has gone the way of the dodo. Even the Kepler Space Telescope is slowly, but surely, going down in flames.

Yet all is not lost for the ailing U.S. space agency. Quietly, in a lab just to the north of Seattle, NASA and its partner Tethers Unlimited are working on something stupendous. For a good long while, rumors and whispers have made the news concerning NASA's testing of how 3D printing might work in zero gravity. Now we know why: NASA is planning to construct the spacecraft of tomorrow with multi-armed robotic, 3D printing spiders.

The robots are called SpiderFab and are designed to be capable of ...

Towards a global quantum network: Photoelectron trapping in double quantum dots

more »

(Phys.org) —While the journey from today's fledgling quantum computers to a global quantum information network may seem daunting, researchers are continually, and at an accelerating pace, making progress towards that goal. One key element essential to that progress is the transfer of quantum information between single photons and solid-state quanta – and the properties of semiconductor quantum dots (QDs) make them excellent candidates for photon-electron quantum coupling. One historical stumbling block has been that although quantum circuits require nondestructive transfer between separate dots, using single QDs usually fails due to destructive transfer in which photoelectrons are immediately lost upon measurement.

Quantum physics concerns a world of infinitely small things. But for years, researchers from the University of Geneva (UNIGE), Switzerland, have been attempting to observe the properties of quantum physics on a larger scale, even macroscopic. In January 2011, they managed to entangle crystals, therefore surpassing the atomic dimension. Now, Professor Nicolas Gisin's team has successfully entangled two optic fibers, populated by 500 photons. Unlike previous experiments which were carried out with the fiber optics of one photon, this new feat (which has been published in Nature Physics) begins to answer a fundamental question: can quantum properties survive on a macroscopic level?

Detection of single photons via quantum entanglement

Almost 200 years ago, Bavarian physicist Joseph von Fraunhofer discovered dark lines in the sun's spectrum. It was later discovered that these spectral lines can be used to infer the chemical composition and temperature of the sun's atmosphere. Today we are able to gain information about diverse objects through light measurements in a similar way. Because often very little light needs to be detected for this, physicists are looking for ever more sensitive spectroscopy methods. In extreme cases, also single particles of light (photons) need to be measured reliably, which is technically challenging.

The coherence of quantum systems is the foundation upon which hardware for future information technologies is based. Quantum information is carried by units called quantum bits, or qubits. They can be used to secure electronic communications – and they enable very fast searches of databases. But qubits are also very unstable. Professors József Fortágh, Dieter Kölle and Reinhold Kleiner of Tübingen's Institute of Physics have developed a new electronic component which will help to deal with this problem. The researchers' long-term goal is to process, transfer and store superposition states such as the overlapping of the binary digits zero and one. The initial results of their work are to be published in the journal Nature Communications on 29 August 2013.

Quantum measurement carries information even when the measurement outcome is unread

(Phys.org) —Some tasks that are impossible in classical systems can be realized in quantum systems. This fact is exemplified by a new protocol that highlights an important difference between classical and quantum measurements. In classical mechanics, performing a measurement without reading the measurement outcome does not carry any information and is therefore equivalent to not performing the measurement at all. But in the new protocol, a quantum measurement that is performed but not read can carry information because the information can be encoded in the choice of the type of measurement that was performed.

This Hubble photograph captures a small region within Messier 17 (M17), a hotbed of star formation. M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the Sagittarius constellation.
Ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds and the warmed surfaces glow orange and red. The intense heat and pressure causes some material to stream away from the surface, creating the glowing veil of even hotter green-coloured gas that masks background structures. The colours in the image represent various gases. Red represents sulphur; green, hydrogen; and blue, oxygen.

Phoenix on Space's Swan Nebula backdrop Galaxy S3 Covers


Galaxies, Stars and Nebulae series Amazingly this could almost be some underwater scene with strange creatures swimming in the aquamarine waters. It's actually the centre of the Swan Nebula, or M17, a hotbed of newly born stars wrapped in colourful blankets of glowing gas and cradled in an enormous cold, dark hydrogen cloud. This stunning picture was taken by the newly installed Advanced Camera for Surveys (ACS) aboard the NASA/ESA Hubble Space Telescope.
The region of the nebula shown in this picture is about 3500 times wider than our Solar System. The area also represents about 60 percent of the total view captured by ACS. The nebula resides 5500 light-years away in the constellation Sagittarius. Like its famous cousin in Orion, the Swan Nebula is illuminated by ultraviolet radiation from young, massive stars - each about six times hotter and 30 times more massive than our Sun.

The powerful radiation from these stars evaporates and erodes the dense cloud of cold gas within which the stars formed. The blistered walls of the hollow cloud shine primarily in the blue, green, and red light emitted by excited atoms of hydrogen, nitrogen, oxygen, and sulphur. Particularly striking is the rose-like feature, seen to the right of centre, which glows in the red light emitted by hydrogen and sulphur.
As the infant stars evaporate the surrounding cloud, they expose dense pockets of gas that may contain developing stars. Because these dense pockets are more resistant to the withering radiation than the surrounding cloud, they appear as sculptures in the walls of the cloud or as isolated islands in a sea of glowing gas. One isolated pocket is seen at the centre of the brightest region of the nebula and is about 10 times larger than our Solar System.

NASA'S Mars Curiosity debuts autonomous navigation

more »

NASA's Mars rover Curiosity has used autonomous navigation for the first time, a capability that lets the rover decide for itself how to drive safely on Mars. This latest addition to Curiosity's array of capabilities will help the rover cover the remaining ground en route to Mount Sharp, where geological layers hold information about environmental changes on ancient Mars. The capability uses software that engineers adapted to this larger and more complex vehicle from a similar capability used by NASA's Mars Exploration Rover Opportunity, which is also currently active on Mars.

Air quality measurements: New manufacturing method for nano gas sensors opens doors

more »

Nano-sized gas sensors in mobile telephones that measure the atmospheric humidity are nothing new as such. However, so far it was necessary to rely on complex lithographic methods to produce the required nano-structure of the sensors, and they have the added disadvantage that they do not work well on uneven surfaces. A relatively new approach is the focussed electron beam deposition method – FEBID for short – in which the nano-structures can be "written directly" without requiring any pre- or after-treatment.

Tessellation patterns that have fascinated mathematicians since Johannes Kepler worked out their systematics 400 years ago – and that more recently have caught the eye of both artists and crystallographers – can now be seen in the laboratory. They first took shape on a surface more perfectly two-dimensional than any sheet of writing paper, a single layer of atoms and molecules atop an atomically smooth substrate. Physicists coaxed these so-called Kepler tilings "onto the page" through guided self-assembly of nanostructures.

Squeezed light produced using silicon micromechanical system

more »

One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as quantum fluctuations, are always present. Always, that is, unless you can pull off a quantum trick. And that's just what a team led by researchers at the California Institute of Technology (Caltech) has done. The group has engineered a miniature silicon system that produces a type of light that is quieter at certain frequencies—meaning it has fewer quantum fluctuations—than what is usually present in a vacuum.

Zero-dimensional transistor harvests bubble energy wasted during water electrolysis

more »

(Phys.org) —When hydrogen is produced from water during electrolysis, some energy is lost as tiny bubbles. In a new study, researchers have demonstrated that 25-nm transistors—so small that they're considered zero-dimensional (0D)—can be used to transform this lost energy into electric pulses. Millions of these 0D transistors could be used to detect individual bubbles and generate electric pulses at an optimal efficiency, gathering part of the energy lost during electrolysis and making it available for other uses.

Quantum measurement carries information even when the measurement outcome is unread

more »

(Phys.org) —Some tasks that are impossible in classical systems can be realized in quantum systems. This fact is exemplified by a new protocol that highlights an important difference between classical and quantum measurements. In classical mechanics, performing a measurement without reading the measurement outcome does not carry any information and is therefore equivalent to not performing the measurement at all. But in the new protocol, a quantum measurement that is performed but not read can carry information because the information can be encoded in the choice of the type of measurement that was performed.

Cosmic turbulences result in star and black hole formation

Just how stars and black holes in the Universe are able to form from rotating matter is one of the big questions of astrophysics. What we do know is that magnetic fields figure prominently into the picture. However, our current understanding is that they only work if matter is electrically well conductive—but in rotating discs this isn't always the case. Now, a new publication by Helmholtz-Zentrum Dresden-Rossendorf physicists in the scientific journal Physical Review Letters shows how magnetic fields can also cause turbulences within "dead zones," thus making an important contribution to our current understanding of just how compact objects form in the cosmos.
