    The distance to the Moon is calculated approximately using the equation: distance = (speed of light × duration of delay due to reflection) / 2. Since the speed of light is a defined constant, conversion between distance and time of flight can be made without ambiguity.

    APOLLO shooting a laser at the Moon. The laser pulse is reflected from the retroreflectors on the Moon (see below) and returned to the telescope. The round-trip time tells the distance to the Moon to great accuracy. In this picture the Moon is very over-exposed, needed to make the laser beam visible. Apollo 15 Lunar Ranging Retro-Reflector (LRRR).

  5. Free-return trajectory - Wikipedia

    en.wikipedia.org/wiki/Free-return_trajectory

    A free-return trajectory may be the initial trajectory to allow a safe return in the event of a systems failure; this was applied in the Apollo 8, Apollo 10, and Apollo 11 lunar missions. In such a case a free return to a suitable reentry situation is more useful than returning to near the Earth, but then needing propulsion anyway to prevent ...

    The NTD was also responsible for the safety of all personnel inside the pad after external tank loading, including the flight crew, about 10 go/no go reports. He reported to the Launch Director, who has another about 5 go/no go reports. [1] The Launch director declares if a mission is go for launch.

    Imagery collected by Voyager 2 of Ganymede during its flyby of the Jovian system Galileo spacecraft encounters asteroid 243 Ida. A flyby (/ ˈ f l aɪ b aɪ /) is a spaceflight operation in which a spacecraft passes in proximity to another body, usually a target of its space exploration mission and/or a source of a gravity assist (also called swing-by) to impel it towards another target.

  9. Spaceflight - Wikipedia

    en.wikipedia.org/wiki/Spaceflight

    Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth , but also includes space probes for flights beyond Earth orbit.
