  2. Orbital propellant depot - Wikipedia

    en.wikipedia.org/wiki/Orbital_propellant_depot

    The main program element was a large-scale, ZBO demonstration using the MSFC multipurpose hydrogen test bed (MHTB) – 18.10 m3 L H 2 tank (about 1300 kg of H 2). A commercial cryocooler was interfaced with an existing MHTB spray bar mixer and insulation system in a manner that enabled a balance between incoming and extracted thermal energy.

  3. List of orbits - Wikipedia

    en.wikipedia.org/wiki/List_of_orbits

    Ecliptic orbit: A non-inclined orbit with respect to the ecliptic. Equatorial orbit: A non-inclined orbit with respect to the equator. Near equatorial orbit: An orbit whose inclination with respect to the equatorial plane is nearly zero. This orbit allows for rapid revisit times (for a single orbiting spacecraft) of near equatorial ground sites.

  4. Near-equatorial orbit - Wikipedia

    en.wikipedia.org/wiki/Near-equatorial_orbit

    A non-inclined orbit is an orbit coplanar with a plane of reference.The orbital inclination is 0° for prograde orbits, and π (180°) for retrograde ones. [citation needed]If the plane of reference is a massive spheroid body's equatorial plane, these orbits are called equatorial, and the non-inclined orbit is merely a special case of the near-equatorial orbit.

  5. Orbital station-keeping - Wikipedia

    en.wikipedia.org/wiki/Orbital_station-keeping

    For example, there are five of these points in the Sun-Earth system, five in the Earth-Moon system, and so on. Spacecraft may orbit around these points with a minimum of propellant required for station-keeping purposes. Two orbits that have been used for such purposes include halo and Lissajous orbits. [5]

  6. Non-rocket spacelaunch - Wikipedia

    en.wikipedia.org/wiki/Non-rocket_spacelaunch

    Non-rocket spacelaunch refers to theoretical concepts for launch into space where much of the speed and altitude needed to achieve orbit is provided by a propulsion technique that is not subject to the limits of the rocket equation. [1] Although all space launches to date have been rockets, a number of alternatives to rockets have been proposed ...

  7. ION Satellite Carrier - Wikipedia

    en.wikipedia.org/wiki/ION_Satellite_Carrier

    ION Satellite Carrier (formerly ION CubeSat Carrier) is a satellite platform developed, manufactured, and operated by Italian company D-Orbit.The platform features a customizable 64U satellite dispenser capable of hosting a combination of CubeSats that fits the volume.

  8. MagBeam - Wikipedia

    en.wikipedia.org/wiki/MagBeam

    The deceleration is accomplished by having another platform at the other end of the journey directing a plasma beam at the payload. By eliminating the mass of the propulsion system from the payload the MagBeam system allows for much faster acceleration and higher top speeds than conventional propulsion systems mounted on the payload.

  9. Distant retrograde orbit - Wikipedia

    en.wikipedia.org/wiki/Distant_retrograde_orbit

    The orbit is "distant" in the sense that it passes above the Lagrange points, rather than being near the moon. Considering more and more distant orbits, the synodic period (the period between two moments when the craft passes between the planet and the moon) gets longer and approaches that of the moon going around the planet.
