  1. 12 de dic. de 2012 · A high-energy rocket is largely responsible for advancing the quest for knowledge and revolutionizing global communications. Its name is Centaur, and it is America’s Workhorse in Space. Centaur is one of Lewis Research Center’s (now NASA Glenn) most significant achievements.

  2. Rocket propellant is the reaction mass of a rocket. This reaction mass is ejected at the highest achievable velocity from a rocket engine to produce thrust. The energy required can either come from the propellants themselves, as with a chemical rocket, or from an external source, as with ion engines .

  3. 21 de feb. de 2023 · Vulcan can do everything from medium lift all the way up to very heavy lift, all with the same family of rockets. Then it has a very capable high-energy upper stage with the latest variant of...

  4. 6 de may. de 2024 · We launch satellites and spacecraft into space by putting them on rockets carrying tons of propellants. The propellants give the rocket enough energy to boost away from Earth’s surface. Because of the pull of Earth’s gravity, largest, heaviest spacecraft need the biggest rockets and the most propellent.

  5. 13 de feb. de 2013 · This light-weight high-energy density material would revolutionize rocketry, allowing single-stage rockets to enter orbit and chemically fueled rockets to explore our solar system. To transform solid molecular hydrogen to metallic hydrogen requires extreme high pressures, but has not yet been accomplished in the laboratory.

  6. 12 de jul. de 2021 · These works provide the guidance for rational design and synthesis of fuels with high energy and high energy density, which are promising for the application in advanced rocket and rocket-based combined cycle engines.
