Space storm alert: 90 seconds from catastrophe

March 30, 2009

A severe coronal mass ejection (plasma balls from the sun) could induce ground currents that would knock out 300 key transformers within about 90 seconds, cutting off the power for more than 130 million people, costing tens of millions of lives, according to a National Academy of Sciences report.

Space to think

August 16, 2007

The present has recently caught up with William Gibson. The great prophet of the digital future, who not only coined the word “cyberspace” in his debut novel Neuromancer in 1984, but imagined its implications and went a long way to suggesting its YouTube and MySpace culture, has stopped looking forwards. “The future is already here,” he is fond of suggesting. “It is just not evenly distributed.” ….

Space-based solar farms power up

February 28, 2013

spsalpha-concept

Space-based solar power (SBSP) has once again begun to attract attention with projects emerging in the US, Russia, China, India and Japan, among others. All are driven by increasing energy demands, soaring oil and gas prices, a desire to find clean alternatives to fossil fuels and by a burgeoning commercial space industry that promises to lower the cost of entry into space and spur on a host of new industries,… read more

Space-elevator tether climbs a mile high

February 16, 2006

LiftPort Group has built a cable for a space elevator stretching a mile into the sky and tethered on balloons, enabling robots to scrabble some way up and down the line.

To make the cable, researchers sandwiched three carbon-fiber composite strings between four sheets of fiberglass tape, creating a mile-long cable about 5 centimeters wide and no thicker than about six sheets of paper.

The aim is to… read more

Spacecraft Saw ULF Radio Emissions over Haiti before January Quake

December 9, 2010

Geoscientists say that the DEMETER satellite saw a clear increase in ultralow frequency radio waves for a period of one month before the M 7.0 earthquake that struck Haiti in January. “The results … clearly indicate that ULF electromagnetic waves can be very useful in revealing possible precursor seismic phenomena,” they suggested.

SpaceX Dragon capsule arrives at Space Station with precious cargo

October 10, 2012

Dragon ISS

A privately built robotic space capsule arrived at the International Space Station early Wednesday (Oct. 10) to make the first-ever commercial cargo delivery to the orbiting lab under a billion-dollar deal with NASA, Space.com reports.

The unmanned Dragon spacecraft was captured by station astronauts using a robotic arm after an apparently flawless approach by the cargo-laden space capsule, which was built by the private spaceflight company SpaceX. It… read more

Spare CPU cycles to be used to further radio astronomy

September 13, 2011

theSkyNet

TheSkyNet project will use the idle time of thousands of PCs to create grid computing power to process massive radio astronomy data sets.

PC users around the world will be asked to contribute spare CPU cycles as part of theSkyNet project to further the science of radio astronomy. Donor PCs will form a distributed computing engine to scan data from telescopes and… read more

Spasers set to sum: A new dawn for optical computing

January 26, 2010

The “spaser,” the latest by-product of a buzzing field known as nanoplasmonics, based on plasmons, may lead to building a super-fast computer that computes with light.

Plasmons, which are ultra-high-frerquency electron waves on a metallic surface, overcome the speed limits of the wires that interconnect transistors in chips, allowing for converting electronic signals into photonic ones and back again with speed and efficiency.
