Researchers And Students To Develop Small CubeSat Satellites, the Size of a Loaf of Bread

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.

Raytheon Develops Technology To Help Aircraft Protect Ground Forces

The U.S. Air Force Research Laboratory has authorized Raytheon Company to demonstrate target recognition technology designed to increase protection for ground forces without compounding risk to an aircraft stalking enemies who threaten those forces.

First in a laboratory and then aloft, the company expects to show how its Air-to-Ground Radar Imaging II program would permit aircraft at a safe distance to detect, track and target hostile forces in motion on the ground.

The laboratory demonstration is expected in autumn 2008, followed by a flight next spring aboard a Raytheon test aircraft.

Flying Wing Surpasses Altitude Records for Non-Rocket Airplane


NASA’s solar-powered Helios experimental aircraft lifted off from a U.S. Navy base on the Hawaiian island of Kauai on Monday, reaching a height of 96,500 feet.

The $15 million aircraft failed in its attempt to reach an altitude of 100,000 feet, but it broke a record set by its predecessor, the Pathfinder Plus, for 80,201 feet for solar-powered and propeller-driven aircraft in 1998.

Officials decided to bring down the radio-controlled Helios at 4:08 p.m. Hawaii time (10:08 p.m. EDT), NASA spokesman Alan Brown told the Associated Press, as the craft had reached a “zero climb rate” in thinning air and slanting sunlight.

Boeing Selected To Design DARPA Space System

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.
