  2. Mars sol - Wikipedia

    en.wikipedia.org/wiki/Mars_sol

    It is approximately 24 hours, 39 minutes, 35 seconds long. A Martian year is approximately 668.6 sols, equivalent to approximately 687 Earth days [ 1 ] or 1.88 Earth years. The sol was adopted in 1976 during the Viking Lander missions and is a measure of time mainly used by NASA when, for example, scheduling the use of a Mars rover .

  3. Timekeeping on Mars - Wikipedia

    The actual landing site was 0.900778° (19.8 km) east of that, corresponding to 3 minutes and 36 seconds later in local solar time. The date is kept using a mission clock sol count with the landing occurring on Sol 0, corresponding to MSD 47776 (mission time zone); the landing occurred around 16:35 LMST, which is MSD 47777 01:02 AMT.

    Marusankakushikaku (Japanese: まるさんかくしかく), [1] also known as , or in English as The Universe, is a zenga by Sengai, a Japanese monk and artist, thought to have been made between 1819 and 1828.

  5. Gravitational singularity - Wikipedia

    en.wikipedia.org/wiki/Gravitational_singularity

    The idea can be stated in the form that, due to quantum gravity effects, there is a minimum distance beyond which the force of gravity no longer continues to increase as the distance between the masses becomes shorter, or alternatively that interpenetrating particle waves mask gravitational effects that would be felt at a distance.

  6. Weightlessness - Wikipedia

    en.wikipedia.org/wiki/Weightlessness

    In the left half, the spring is far away from any gravity source. In the right half, it is in a uniform gravitation field. a) Zero gravity and weightless b) Zero gravity but not weightless (Spring is rocket propelled) c) Spring is in free fall and weightless d) Spring rests on a plinth and has both weight 1 and weight 2.

  7. Ma (negative space) - Wikipedia

    en.wikipedia.org/wiki/Ma_(negative_space)

    In modern interpretations of traditional Japanese arts and culture, ma is an artistic interpretation of an empty space, often holding as much importance as the rest of an artwork and focusing the viewer on the intention of negative space in an art piece. The concept of space as a positive entity is opposed to the absence of such a principle in ...

  8. Zero Gravity Research Facility - Wikipedia

    en.wikipedia.org/wiki/Zero_Gravity_Research_Facility

    The Zero Gravity Research Facility was built in 1966 as part of NASA's Centaur upper-stage rocket development program. In order to ensure proper firing and functioning of upper-stage rockets, NASA needed to understand the behavior of fluids (importantly, the liquid gases fueling the rockets), in the reduced gravity where they would fire.
