  2. Space launch - Wikipedia

    en.wikipedia.org/wiki/Space_launch

    Space launch is the earliest part of a flight that reaches space. Space launch involves liftoff, when a rocket or other space launch vehicle leaves the ground, floating ship or midair aircraft at the start of a flight. Liftoff is of two main types: rocket launch (the current conventional method), and non-rocket spacelaunch (where other forms of ...

  3. Roll program - Wikipedia

    en.wikipedia.org/wiki/Roll_program

    The rocket simply initiated its roll program at the appropriate time after launch, and rolled until an adequate amount of time had passed to ensure that the desired roll angle was achieved. [ 3 ] Roll on the Saturn V was initiated by tilting the engines simultaneously using the roll and pitch servomechanisms , which served to initiate a rolling ...

  4. UP Aerospace - Wikipedia

    en.wikipedia.org/wiki/UP_Aerospace

    UP Aerospace was started in 1998 [2] by Jerry Larson, an aerospace engineer who had long been involved in the space program as an employee of Lockheed Martin. Larson was also a member of the Civilian Space eXploration Team (CSXT), which in 2004 became the first amateur organization to launch a (suborbital) rocket into space. The company was ...

  5. Hohmann transfer orbit - Wikipedia

    en.wikipedia.org/wiki/Hohmann_transfer_orbit

    Space missions using a Hohmann transfer must wait for this required alignment to occur, which opens a launch window. For a mission between Earth and Mars, for example, these launch windows occur every 26 months. A Hohmann transfer orbit also determines a fixed time required to travel between the starting and destination points; for an Earth ...

  6. Orbital spaceflight - Wikipedia

    en.wikipedia.org/wiki/Orbital_spaceflight

    Some of these ideas such as the space elevator, and rotovator, require new materials much stronger than any currently known. Other proposed ideas include ground accelerators such as launch loops, rocket-assisted aircraft/spaceplanes such as Reaction Engines Skylon, scramjet powered spaceplanes, and RBCC powered spaceplanes. Gun launch has been ...

  8. Launch window - Wikipedia

    en.wikipedia.org/wiki/Launch_window

    In the context of spaceflight, launch period is the collection of days, and launch window is the time period on a given day, during which a particular rocket must be launched in order to reach its intended target. [1] [2] If the rocket is not launched within a given window, it has to wait for the window on the next day of the period. [3]

  9. Spacecraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_flight_dynamics

    The principles of flight dynamics are used to model a vehicle's powered flight during launch from the Earth; a spacecraft's orbital flight; maneuvers to change orbit; translunar and interplanetary flight; launch from and landing on a celestial body, with or without an atmosphere; entry through the atmosphere of the Earth or other celestial body ...
