  2. Relativistic rocket - Wikipedia

    en.wikipedia.org/wiki/Relativistic_rocket

    Relativistic rocket means any spacecraft that travels close enough to light speed for relativistic effects to become significant. The meaning of "significant" is a matter of context, but often a threshold velocity of 30% to 50% of the speed of light (0.3 c to 0.5 c ) is used.

  3. Comparison of orbital launch systems - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_orbital...

    All launch vehicle propulsion systems employed to date have been chemical rockets falling into one of three main categories: Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants, typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder. The ...

    en.wikipedia.org/wiki/Ansari_X_Prize

    The X Prize was inspired by the Orteig Prize—the 1919 prize worth 25,000 dollars offered by New York hotel owner Raymond Orteig that encouraged a number of intrepid aviators in the mid-1920s to fly across the Atlantic Ocean from New York to Paris—which was ultimately won in 1927 by Charles Lindbergh in his aircraft Spirit of St. Louis.

  5. Orbital mechanics - Wikipedia

    en.wikipedia.org/wiki/Orbital_mechanics

    Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets, satellites, and other spacecraft.

    The facility is located atop a 1,740 ft (530.35 m) hill in Vestal, New York, 13 mi (20.92 km) southwest of Binghamton, New York within the Allegheny Plateau. [24] The site lies on the western ridge line of the Choconut Creek, [ 25 ] part of the Susquehanna River Basin , a few hundred feet north of the New York – Pennsylvania border.

  7. Field propulsion - Wikipedia

    en.wikipedia.org/wiki/Field_propulsion

    In the general relativistic field propulsion system space is considered to be an elastic field similar to rubber which means that space itself can be treated as an infinite elastic body. If the space-time curves, a normal inwards surface stress is generated which serves as a pressure field.

  8. Bell's spaceship paradox - Wikipedia

    en.wikipedia.org/wiki/Bell's_spaceship_paradox

    This means, by definition, that with respect to S the distance between the two rockets does not change even when they speed up to relativistic velocities." [1] Then this setup is repeated again, but this time the back of the first rocket is connected with the front of the second rocket by a silk thread. They concluded:

  9. Terran R - Wikipedia

    en.wikipedia.org/wiki/Terran_R

    On 12 April 2023, after the first flight of the Terran 1, Relativity Space CEO Tim Ellis announced that the rocket was no longer going to be further developed and focus would move to Terran R. [6] The new version of the rocket will have a maximum payload capacity of 23,500 kg (51,800 lb) to low earth orbit (LEO) with a fully reusable first stage, and 33,500 kg (73,900 lb) to LEO if fully expended.
