Latest Spacecraft propulsion Stories
A United Launch Alliance (ULA) Delta IV rocket successfully launched the AFSPC-4 mission for the U.S. Air Force on July 28 at 7:28 p.m. EDT from Space Launch Complex-37.
From hopping/tumbling robots to gecko-inspired adhesives, a variety of technologies have been chosen by NASA for flight on commercial reusable launch vehicles and a commercial parabolic aircraft.
After eight years in orbit, ESA’s Venus Express has completed routine science observations and is preparing for a daring plunge into the planet’s hostile atmosphere.
Critical engine technology validates green propellant advantages over hydrazine BOULDER, Colo., March 31, 2014 /PRNewswire/ -- Ball Aerospace & Technologies Corp.
NASA's X-43A shattered existing speed records for aircraft with air-breathing engines on March 27, 2004, when the scram-jet powered plane reached Mach 6.83 - 4,900 miles per hour - during a brief flight over the Pacific Ocean.
WASHINGTON, March 25, 2014 /PRNewswire-USNewswire/ -- NASA is seeking proposals from U.S.
To better understand the heating conditions at the base of what will be the biggest, most powerful rocket ever built, engineers at NASA's Marshall Space Flight Center in Huntsville, Ala., are thinking small -- really small.
How to design a hypersonic airplane that travels from Beijing to New York in only two hours? Dr. Cui Kai and his group from State Key Laboratory of High Temperature Gas Dynamics, Institute of Mechanics, Chinese Academy of Sciences set out to tackle this problem.
Since Robert Goddard's first launch of a liquid propellant rocket in 1926, experts have worked to perfect engine propulsion systems. As launch vehicles have grown in size, fuel and oxidizer tanks have become more complex resulting in unexpected changes in thrust, potentially endangering flight crews and mission success.
Escape Velocity -- An escape velocity is the minimum speed at which an object without propulsion can move away from a source of a gravitational field indefinitely if there is no friction. This definition may need modification for the practical problem of two or more sources in some cases. In any case, the object is assumed to be a point with a mass that is negligible compared with that of the source of the field, usually an excellent approximation. It is commonly described as the speed...
