International Group Studies Mars Sample Return Mission

Until humans can actually set foot on the Red Planet, the next best thing would be a sample return mission, to bring Martian soil samples back to Earth. A sample return would exponentially increase our knowledge and understanding Mars and its environment. And in order to pull off a mission of this magnitude, international cooperation might be required, and in fact, may be preferred. The International Mars Exploration Working Group (IMEWG), organized an international committee to study an international architecture for a Mars Sample Return (MSR) mission concept. After several months of collective work by scientists and engineers from several countries worldwide, the “iMARS� group is ready to publish the outcome of its deliberations and the envisioned common architecture for a future international MSR mission, and they will discuss thei

The Criterion Collection's Reference Blu-ray Player: The Playstation 3

ps3120-3.jpgThe folks at the Criterion Collection know a thing or two about movies. They restore classic films for release on DVD and, starting later this year, Blu-ray. So when they set up their screening rooms, you'd expect them to have some crazy $1,000 Blu-ray player, right? Nope. The Criterion Collection people rock a PlayStation 3 for use as their reference Blu-ray player. If you needed further proof that the PS3 is the best Blu-ray player out there, now you have it. [CNET]

Focusing on nanotechnology - pushing the limits of X-ray microscopy

(Nanowerk Spotlight) X-rays are at the short wavelength, high energy end of the electromagnetic spectrum (only gamma rays have shorter wavelength and carry more energy) and this form of radiation is primarily used for crystallography and diagnostic radiography. Due to the high energy they carry, and because their wavelengths are on the order of the size of atoms, X-rays can penetrate deeply into a material. Chances are you've had an 'X-ray' taken at least once in your life by your doctor or dentist but you will have also encountered X-ray machines at airport security (the machines your carry-on luggage is going through). X-rays play an important role in microscopy and X-ray microscopes have become very powerful scientific instruments for domains such as nanotechnology, materials and life sciences, microelectronics, and chemistry.

The Gamma-Ray Large Area Space Telescope (GLAST) was launched by NASA on 11 June from the Cape Canaveral Air Force Station in Florida. GLAST is a next-generation, high-energy, gamma-ray observatory, designed to explore some of the most energetic phenomena in the universe and enhance knowledge of fundamental physics, astronomy and cosmology. It is an international, multi-agency mission with important contributions from research institutions in France, Germany, Italy, Japan, Sweden and the US.

Proposed Particle Help Explains Odd Galactic Photons

In 2002, a satellite called INTEGRAL was launched by the European Space Agency with an instrument on board to detect and measure gamma rays from space. Four years later, it yielded some intriguing data: An unusually high number of gamma-ray photons from the galactic center carried the same energy—a particular, significant energy—and nobody could figure out why.

Object intermediate between normal supernovae and gamma-ray bursts found

A European-led team of astronomers are providing hints that a recent supernova may not be as normal as initially thought. Instead, the star that exploded is now understood to have collapsed into a black hole, producing a weak jet, typical of much more violent events, the so-called gamma-ray bursts.

Astronomers Locate High Energy Emissions from the Crab Nebula

Scientists studying the Crab Nebula have discovered high energy gamma rays around the rotation-powered pulsar, the neutron star at the center of this enigmatic nebula. Neutron stars accelerate particles to immense energies, typically one hundred times more than the most powerful accelerators on Earth. Scientists have been uncertain exactly how these systems work and where the particles are accelerated. But by using the gamma-ray telescope on the European Space Agency's INTEGRAL spacecraft orbiting Earth, astronomers have detected polarized gamma-rays emitting from near the pulsar.

The Yin and Yang of the NeXT Spacecraft

Hard and soft. Dark and bright. High and low. Wide and thin. JAXA and NASA. And that's just one spacecraft. Japan's space agency, JAXA and NASA are teaming up to create a new spacecraft to study the extreme environments of the universe. NeXT, which stands for New exploration X-Ray Telescope is a next generation x-ray astronomy satellite currently under development, with launch scheduled in 2013. While Japan will provide the main spacecraft and several instruments, NASA, and in particular the Goddard Space Flight Center just announced they will be adding a new instrument to the spacecraft, the High-Resolution Soft X-Ray Spectrometer (SXS). While the spacecraft's main instrument will be its Hard X-ray Telescope (HXTs) the addition of SXS is just one of several complementary instruments that provide a "yin and yang" aspect to NeXT's explorat

Ray Bradbury Turns 88

Lawrence Person writes "Legendary science fiction writer Ray Bradbury turned 88 years old on August 22. Happy Birthday Ray! 'The Illustrated Man' was one of the first science fiction books I ever read, and I've been hooked ever since. I'm sure that's true of a lot of science fiction writers and readers, be it that, or 'The Martian Chronicles,' or 'Fahrenheit 451.' There are also several videos of Ray on that page, including one where he doesn't endorse Sunsweet Prunes." I remember when another student on the bus loaned me "Fahrenheit 451," and my middle-school English teacher Mrs. Young was smart enough to include "All Summer in a Day" in her curriculum.

Massively Parallel X-Ray Holography

Roland Piquepaille writes "An international group of scientists has produced some of the sharpest x-ray holograms of microscopic objects ever made. According to one of them, they improved the efficiency of holography by a factor of 2,500. In order to achieve these spectacular results, they put a uniformly redundant array next to the object to image. And they found that this parallel approach multiplied 'the efficiency of X-ray Fourier transform holography by more than three orders of magnitude, approaching that of a perfect lens.' Besides these impressive achievements, it's worth noting that this technology has been inspired by the pinhole camera, a technique used by ancient Greeks. 'By knowing the precise layout of a pinhole array, including the different sizes of the different pinholes, a computer can recover a bright, high-resolution i
