SpaceX reuses the Falcon 9 boosters over and over. The second stage for each Falcon 9 launch is new, burning up in the atmosphere after deploying its payload. During a webcast of the mission, an unusual buildup of ice could be seen on the side of the rocket with chunks breaking away. ...
But the biggest problem of all is harnessing enough energy simply to get a spaceship off the ground. That is where rocket engines come in. Rocket Image Gallery Rocket engines are, on the one hand, so simple that you can build and fly your own model rockets very inexpensively (see the lin...
The activity was classified as unusual by North Korean rocket experts in the report, given that countries typically allow rocket stages to fall naturally into Earth's atmosphere— absent the ability to land the first stage, like Sp...
“Shutdown of a Raptor vacuum engine in slow motion,” SpaceX said in a message accompanying the video (below). It added that the engine’s nozzle “is sized for use by Starship in the Earth’s upper atmosphere and outer space, so operation at sea level and low chamber pressures results...
Eclipsing even NASA's legendary Apollo Saturn 5 in raw power, the SLS's Northrop Grumman-built strap-on boosters burned through 5.5 tons of propellant per second propelling the rocket out of the dense lower atmosphere. Two minutes and 10 seconds after launch, they burned out and fell away at...

Sea Launch manifest for 2012 includes Intelsat 19 in the spring and Intelsat 21 in the fall. [Spaceflight Now – 01/25/2012]Russia’s Chibis (Peewit) microsatellite, which studies gamma-radiation generated by lightning in the atmosphere, is placed into orbit from the International Space Station...
The kerosene likely burned off in the explosion, while the liquid oxygen will dissipate into the atmosphere, said Orbital executive vice president Frank Culbertson. But the second stage contains potentially hazardous solid fuel that may have survived the blast, and the Cygnus spacecraft's hydrazine ...
