Ariane 5 Booster Undergoes Test Fire
2012-05-26 03:00:24

An Ariane 5 solid-propellant booster was test-fired on Thursday, May 24 at Europe´s Spaceport in French Guiana to help improve the reliability of Europe´s heavy launcher. The firing was performed in the booster engine stand, specifically designed for the vertical testing of motors at the site. The motor burned for about 135 seconds, simulating the firing time during an Ariane 5 flight, and delivered a mean thrust of 700 t. One of the goals was to prove new, thinner thermal...

[ Watch the Video ] Early Wednesday morning, an Ariane 5 launcher lifted off from Europe´s Spaceport in French Guiana on its mission to place two telecommunications satellites, JCSAT-13 and Vinasat-2, into their planned transfer orbits. Liftoff of flight VA206, the 62nd Ariane 5 mission, came at 22:13 GMT (00:13 CEST; 19:13 French Guiana). The target injection orbit had a perigee altitude of 249.9 km, an apogee altitude at injection of 35 911 km and an inclination of 2°. The...

A sub-scale solid rocket motor designed to mimic NASA's Space Launch System, or SLS, booster design successfully was tested today by engineers at NASA's Marshall Space Flight Center in Huntsville, Ala. The 20-second firing tested new insulation materials on the 24-inch-diameter, 109-inch-long motor. The motor is a scaled down, low-cost replica of the solid rocket motors that will boost SLS off the launch pad. Marshall is leading the design and development of the SLS on behalf of the...

For the first time, NASA has released high-definition video taken during the retrieval of solid rocket booster segments from the Atlantic Ocean. The solid rocket boosters provided 144 million horsepower of thrust for the final launch of space shuttle Discovery on its STS-133 mission. After each shuttle launch, crew members of the Liberty Star and Freedom Star retrieval ships pull the spent boosters out of the ocean and return them to Hangar AF at Cape Canaveral Air Force Station in Florida....

Trinitramid "“ that's the name of the new molecule that may be a component in future rocket fuel. This fuel could be 20-30 percent more efficient in comparison with the best rocket fuels we have today. The discovery was made at the Royal Institute of Technology (KTH) in Sweden. "A rule of thumb is that for every ten-percent increase in efficiency for rocket fuel, the payload of the rocket can double. What's more, the molecule consists only of nitrogen and oxygen, which would make the...

Researchers are developing a new type of rocket propellant made of a frozen mixture of water and "nanoscale aluminum" powder that is more environmentally friendly than conventional propellants and could be manufactured on the moon, Mars and other water-bearing bodies. The aluminum-ice, or ALICE, propellant might be used to launch rockets into orbit and for long-distance space missions and also to generate hydrogen for fuel cells, said Steven Son, an associate professor of mechanical...

NASA and the Air Force Office of Scientific Research, or AFOSR, have successfully launched a small rocket using an environmentally-friendly, safe propellant comprised of aluminum powder and water ice, called ALICE."This collaboration has been an opportunity for graduate students to work on an environmentally-friendly propellant that can be used for flight on Earth and used in long distance space missions," said NASA Chief Engineer Mike Ryschkewitsch at NASA Headquarters in Washington. "These...
