The new version of Starship will be tested again in four to six weeks. A third consecutive failure could indicate fundamental ...

A new group of 18 satellites entered orbit Tuesday for the Thousand Sails constellation with the first launch from a new ...

Basically, cryogenic propellants are liquid oxygen, liquid methane, and liquid hydrogen. To put this into perspective, liquid oxygen vapors off at just -297.3°F. Cryogenic propellants have been viewed ...

Since the launch of a rocket in 2021 called Emergence 1, the University of Akron's rocket design team has had one goal: to ...

Gelled propellants are produced from liquid propellants with the addition of gelling agents. They are solid at rest, for example in a tank, and become flowable under the influence of shear stress, as ...

But the twentieth-century saw a technological explosion of new rocket-propulsion systems, using both solid and liquid propellants. Rocket-powered vehicles were developed for two primary purposes: ...

This article was originally published with the title “ Liquid-Propellant Rocket Development ” in Scientific American Magazine Vol. 155 No. 2 (August 1936), p. 78 doi:10.1038 ...

While we’re reluctant to say it for fear of being misinterpreted, the new liquid fuel rocket engine being built by Copenhagen Suborbitals is one of the most impressive, daring, and nearly the ...

"Propellant gauging has long been a problem," Collicott said. "I am not saying by any means that this has the whole thing solved." The technique also might be used to help design satellite fuel tanks ...

He said some advanced liquid propellants can be stored in missiles for a few weeks before liftoffs. Lee said North Korea may ...

All rockets used some form of solid or powdered propellant up until the 20th century, when liquid-propellant rockets offered more efficient and controllable alternatives. Solid rockets are still used ...
