Crowdsource the launch of a nano-satellite into space – Kickstarter

We are developing a nano-satellite, and mobile apps to go with it, as the focus for a global education and public outreach campaign. The satellite, called SkyCube, is a 10x10x10 cm “1U” CubeSat intended for launch as a secondary payload on a SpaceX Falcon 9 rocket in 2013. Orbiting more than 300 miles up, on a path highly inclined to the Earth’s equator, SkyCube will pass over most of the world’s inhabited regions.

SkyCube will take low-resolution pictures of the Earth and broadcast simple messages uploaded by sponsors. After 90 days, it will use an 8-gram CO2 cartridge to inflate a 10-foot (3-meter) diameter balloon coated with highly reflective titanium dioxide powder. SkyCube’s balloon will make the satellite as bright as the Hubble Space Telescope or a first-magnitude star. You’ll be able to see it with your own eyes, sailing across the sky. But SkyCube’s balloon isn’t just for visibility. It will – within 3 weeks – bring SkyCube down from orbit due to atmospheric drag, ending the mission cleanly in a fiery “grand finale” that avoids any buildup of space debris.

 

PLEDGES

$1 - Sponsors 10 seconds of the mission. You can broadcast one (1) 120-character message from the satellite.

$6 - Sponsors 1 minute of the mission. You can broadcast six (6) 120-character messages from space, and request one (1) image from the satellite.

$100 - Sponsors 15 minutes of the mission. An ideal family pack – we’ll send you two (2) SkyCube mission T-shirts! And you can broadcast one hundred (100) 120-character messages from the satellite, and request twenty (20) images from the satellite at any time during the mission.

$1,000 – Sponsors 2 hours of the mission – a great high school or university classroom sponsorship package. We’ll send you a radio receiver which you can use to detect transmissions from SkyCube and other satellites already in orbit! You’ll also get a flying SpaceX Falcon 9 model rocket, and twenty (20) SkyCube mission T-shirts. You can broadcast one thousand (1000) 120-character messages from space, and request up to two hundred (200) images from the satellite.

Scientists build first working quantum network – mind-bogglingly powerful

Scientists at the Quantum Dynamics division of the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany announced Wednesday that they have built the very first, elementary quantum network comprised of a pair of entangled atoms that transmit information to each other via single photons.

That and a couple of bucks will get you a cup of coffee, plus anything from a perfectly secure data exchange system to the massive scaling via distributed processing of the already mind-bogglingly powerful, if theoretical, potential of a standalone quantum computer.

These are indeed heady days for the pioneers of quantum computing, with each news cycle seemingly bringing forth a major breakthrough in a subatomic frontier that appears poised to revolutionize how our calculating machines deliver us everything from satellite mapping to LOLcats.

 

Building it was the hardest part:

…had to figure out a means of exercising “perfect control” over all the components in their quantum network, which first meant getting the two atoms that make up the network’s receptor nodes to somehow stay stationary, because a couple of free-floating atoms wouldn’t be able to communicate with the photons relaying information between the two very efficiently.

The team was able to fix their atoms in optical cavities, basically a couple of highly reflective mirrors a short distance from each other, by means of fine-tuned laser beams.
