... VSS Enterprise and the other Virgin Galactic sub-orbital spaceships will have two pilots. This is an important safety measure and also of course provides for pilot training in much the same ...
Cassini is an international mission that was conceived in the 1980s, and begun in 1990, to launch a ...
... V of almost 328 feet per second. With this velocity change the rocket can reach an altitude of more than 1,300 feet. High ... the trip to orbit suffers several kinds of losses and some extra velocity is required to overcome losses such as steering, altitude, drag and gravity losses ... requires about 30,000 feet per second of delta V. To escape the Earth's gravity field from LEO requires another 9,800 ...
... a high velocity. The momentum of the exhaust mass creates a reactive force on the rocket vehicle. Possibly the simplest example is a balloon. When inflated and released the air inside is squeezed ... air escapes in one direction, the balloon, and the remaining air inside it, is pushed in the opposite direction. The balloon's motion is usually quite erratic because the direction of the escaping air is ...
... would be an area of space where no material could fall in, and in fact it would actually allow matter to escape into space. This is a white hole. Now, if there is a rotating black hole in space, there is a chance for an object to fall into a ... within our Universe or perhaps be connected to different universes. Now that I have described what it is, I must emphasize that scientists currently do not believe white holes or worms holes ...
... pound of propellant. So, Isp is independent of the system of units: metric or English. Isp can be calculated from the specific energy or from the exhaust velocity. For LOX/ RP1 and for solid rocket motors, the Isp is about 300 seconds. For LOX/ hydrogen the Isp is about 460 seconds. Nuclear thermal rockets have an Isp of about 1,000 seconds and electric thrusters provide an Isp of 1,000 to 10,000 ...
