Latest Spacecraft propulsion Stories
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.
After a spectacular launch, the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft was placed by the Minotaur V launch vehicle into an elliptic orbit around Earth, as the start of our journey to the moon.
Ion propulsion used to exist only in the imagination of science fiction writers.
Nanosatellites are smartphone-sized spacecraft that can perform simple, yet valuable, space missions. Dozens of these little vehicles are now tirelessly orbiting the earth performing valuable functions for NASA, the Department of Defense and even private companies.
The largest 3D printed rocket engine component ever tested by NASA produced a record 20,000 pounds of thrust during an engine firing last Thursday, officials at the US space agency have revealed.
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...
