- Lowering the Cost of Space Flight.
New propulsion system harnesses Earth's magnetic field. Launching a satellite or spacecraft into orbit isn't cheap: It can I cost up to $10,000 Per pound, plus an extra $7,000 per pound to maneuver the craft once it's up there. Considering that most of a craft's weight is fuel, there must ......
- New technology to control gravity in space flight
Pasadena, Calif.-NASA's New Millennium Program has selected two organizations to lead the work on sensor and thrust-producing technologies to control a space vehicle's flight path so the payload responds only to gravitational forces. The Disturbance Reduction System technology is on tap to fly in 2006 as the Space Technology 7 ......
- Nickel-hydrogen batteries power Mars mission
NASA Tech Briefs reports that NASA's 2001 Mars Odyssey spacecraft, launched this spring, was expected to arrive at Mars in late October to join the Mars Global Surveyor, which already is in orbit. A probe will search for and analyze various elements of the Martian environment, such as water, ice, ......
- Air-breathing rocket passes one-hour milestone
NASA engineers at the Marshall Space Flight Center in Huntsville Ala., together with those from its industry partner, Rocketdyne, Canoga Park, Calif., completed one hour of testing on an air-breathing rocket - also known as a rocket-based, combined cycle engine. It marks the most time accumulated on such an engine....
- High-friction coating puts the brakes on descent to Mars
In January, the Mars Exploration Rover (MER) will enter the red planet's atmosphere where an entry, descent, and landing system will drop the spacecraft's speed from 17,000 mph to zero as the Lander settles on the planet surface. Key to the Rover's soft landing is a descent-rate limiter that will ......
- Power from space
News Researchers at NASA's Marshall Space Flight Center, Huntsville, Ala., have devised a spacecraft that draws power from the Earth's magnetic field. Proseds, for Propulsive Small Expendable Deployer system, uses a tether to collect electrical current along its length as it orbits the Earth. A device, called a hollow-cathode plasma ......
- Better spacecraft
NASA's Rapid Spacecraft Acquisition program is the latest in a long line of innovative contracting strategies at the agency. The RSA program, based at Goddard Space Flight Center in Greenbelt, Md., was born in 1996, when Goddard top management issued a challenge to reduce the lead time of awarding spacecraft ......
