A CubeSat is a type of space research picosatellite with dimensions usually of 10×10×10 centimetres (i.e., a volume of exactly one litre), weighing no more than one kilogram, and typically using commercial off-the-shelf electronics components.

Developed through joint efforts, California Polytechnic State University and Stanford University introduced the CubeSat to academia as a way for universities throughout the world to enter the realm of space science and exploration.

Currently, a large number of universities and some companies and other organizations around the world are actively developing CubeSats. One of these companies Clyde-Space, has just developed an ‘off-the-shelf’ website with information and resources for various sized cubesats and their subsystems. Other suppliers such as ISIS and GomSpace are also offering products and services through their websites.
With their relatively small size, CubeSats can be made and launched for an estimated US$65,000–80,000 each (2004 US dollars). This low price tag, as compared to most satellite launches, has made Cubesat a viable option for schools and universities across the world.

In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn’t shine.

Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is prohibitively expensive and grossly inefficient. With this announcement, MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy.

Brent Christner, LSU professor of biological sciences, in partnership with colleagues in Montana and France, recently found evidence that rain-making bacteria are widely distributed in the atmosphere. These biological particles could factor heavily into the precipitation cycle, affecting climate, agricultural productivity and even global warming. Christner and his colleagues published their results on Feb 29 in the journal Science.

Applied scientists at Harvard University in collaboration with researchers from the German universities of Jena, Gottingen, and Bremen, have developed a new technique for fabricating nanowire photonic and electronic integrated circuits that may one day be suitable for high-volume commercial production.

Fabrication technique could yield low-cost, scalable nanowire photonic and electronic circuits

Spearheaded by graduate student Mariano Zimmler and Federico Capasso, Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electrical Engineering, both of Harvard’s School of Engineering and Applied Sciences (SEAS), and Prof. Carsten Ronning of the University of Jena, the findings will be published in Nano Letters. The researchers have filed for U.S. patents covering their invention.

A team led by Boeing has been selected by the Defense Advanced Research Projects Agency (DARPA) to demonstrate initial technologies for a new spacecraft system architecture concept.A $12,891,049 cost-plus-fixed-fee, 12-month Phase 1 contract was awarded to Boeing Advanced Systems to research, design, develop and test DARPA’s Future, Fast, Flexible, Fractionated, Free-Flying Spacecraft United by Information Exchange (System F6) space technology and demonstration program.

The DARPA System F6 is based on a concept whereby a group of spacecraft operate together wirelessly as a single unit to enable flexible data sharing and distributed processing that will allow cooperative communications among the spacecraft. This concept of multiple spacecraft operating together to perform a mission similar to that of a single larger spacecraft is known as “fractionation.”

“We believe the fractionation spacecraft concept proposed by our team can be a game-changer that could provide the high degree of flexibility needed for responsive space missions,” said Bob Friend, director for Boeing Operationally Responsive Space.

If you could hold a giant magnifying glass in space and focus all the sunlight shining toward Earth onto one grain of sand, that concentrated ray would approach the intensity of a new laser beam made in a University of Michigan laboratory.
“That’s the instantaneous intensity we can produce,” said Karl Krushelnick, a physics and engineering professor. “I don’t know of another place in the universe that would have this intensity of light. We believe this is a record.”

The pulsed laser beam lasts just 30 femtoseconds. A femtosecond is a millionth of a billionth of a second. The beam is twice as intense as one the researchers produced in 2004.

Such intense beams could help scientists develop better proton and electron beams for radiation treatment of cancer, among other applications.

Astronomers from Arecibo Observatory radio telescope in Arecibo, Puerto Rico, have detected for the first time the molecules methanimine and hydrogen cyanide - two ingredients that build life-forming amino acids - in a galaxy some 250 million light years away. “Just add water!” said Robert Minchin, an Arecibo astronomer on the project, who explained that methanimine and hydrogen cyanide are two of the basic ingredients of life, because when combined with water they form glycine, the simplest amino acid, a building block of life on Earth.

The astronomy team, led by Arecibo astronomer Christopher Salter, announced this discovery today (Jan. 11) in a poster presented at the American Astronomical Society meeting in Austin. The Arecibo Observatory is managed by Cornell University for National Science Foundation.

The Arecibo astronomers focused on the distant galaxy Arp 220, an ultra-luminous starburst galaxy, because it forms new stars at a very high rate. They used the 305-meter, or 1,000-foot diameter, Arecibo radio telescope, the world’s largest and most sensitive, to observe the galaxy at different frequencies. In fact, for the first time in April 2007, they used the 800 megahertz wide-band mode of the main spectrometer to make these detections.

An ambitious government plan seeks to make Korea one of the top three countries for nanotechnology by 2020.

The Science and Technology Ministry announced Tuesday (Jan. 15) its “National Nanotechnology Roadmap (2007-2020)” for research and development in the field.

The Korea Nanotechnology Research Society drew up the plan, and will also hold a public hearing on the roadmap Thursday.

Carbon nanotubes have a sound future in the electronics industry, say researchers who built the world’s first all-nanotube transistor radios to prove it.

The nanotube radios, in which nanotube devices provide all of the active functionality in the devices, represent “important first steps toward the practical implementation of carbon-nanotube materials into high-speed analog electronics and other related applications,” said John Rogers, a Founder Professor of Materials Science and Engineering at the University of Illinois.

Rogers is a corresponding author of a paper that describes the design, fabrication and performance of the nanotube-transistor radios, which were achieved in a close collaboration with radio frequency electronics engineers at Northrop Grumman Electronics Systems in Linthicum, Md.

The paper has been accepted for publication in the Proceedings of the National Academy of Sciences, and is to be published in PNAS Online Early Edition next week.

Contact Lenses With Circuits, Lights A Possible Platform For Superhuman Vision

Movie characters from the Terminator to the Bionic Woman use bionic eyes to zoom in on far-off scenes, have useful facts pop into their field of view, or create virtual crosshairs. Off the screen, virtual displays have been proposed for more practical purposes — visual aids to help vision-impaired people, holographic driving control panels and even as a way to surf the Web on the go.

The device to make this happen may be familiar. Engineers at the University of Washington have for the first time used manufacturing techniques at microscopic scales to combine a flexible, biologically safe contact lens with an imprinted electronic circuit and lights.
