  2. Earthshaker! (pinball) - Wikipedia

    en.wikipedia.org/wiki/Earthshaker!_(pinball)

    About 200 of these sample machines were produced before this toy was made stationary due to cost savings. [1] Some hobbyists re-add this feature in their custom pinball machines. [8] The music and voices of the game are typical for its era, although the pinball machine is known for a female voice saying "Bitchin'!" which was unusual for its time.

  3. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    The troposphere is the lowest layer of Earth's atmosphere. It extends from Earth's surface to an average height of about 12 km (7.5 mi; 39,000 ft), although this altitude varies from about 9 km (5.6 mi; 30,000 ft) at the geographic poles to 17 km (11 mi; 56,000 ft) at the Equator, [17] with some variation due

  4. Exosphere - Wikipedia

    en.wikipedia.org/wiki/Exosphere

    The layers are to scale. From the Earth's surface to the top of the stratosphere (50km) is just under 1% of Earth's radius. The exosphere is a thin, atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is so low that the molecules are essentially collision ...

  5. Planetary boundary layer - Wikipedia

    en.wikipedia.org/wiki/Planetary_boundary_layer

    In addition to the surface layer, the planetary boundary layer also comprises the PBL core (between 0.1 and 0.7 of the PBL depth) and the PBL top or entrainment layer or capping inversion layer (between 0.7 and 1 of the PBL depth). Four main external factors determine the PBL depth and its mean vertical structure: the free atmosphere wind speed;

  6. Pat Lawlor - Wikipedia

    en.wikipedia.org/wiki/Pat_Lawlor

    Lawlor's pinball career began as an engineer for Williams in 1987, when he co-designed a dual-playfield machine called Banzai Run with Larry DeMar. In 1988, he was assigned his first individual design project, a machine entitled Earthshaker!, which was released in January 1989. Notably, Earthshaker! was the first pinball machine with a shaker ...

  7. Aura (satellite) - Wikipedia

    en.wikipedia.org/wiki/Aura_(satellite)

    Aura (EOS CH-1) is a multi-national NASA scientific research satellite in orbit around the Earth, studying the Earth's ozone layer, air quality and climate. [2] It is the third major component of the Earth Observing System (EOS) following on Terra (launched 1999) and Aqua (launched 2002). Aura follows on from the Upper Atmosphere Research ...

    Carries six instruments to observe interactions among the four spheres for Earth's systems: oceans, land, atmosphere, and biosphere. [5] ASNARO-2: Active JAXA: 2018 Aura: Active NASA 2004 Studies earth's ozone, air quality, and climate though observation of composition, chemistry, and dynamics of the atmosphere.

  9. Terrestrial atmospheric lens - Wikipedia

    en.wikipedia.org/wiki/Terrestrial_atmospheric_lens

    The sun's image appears about a half degree above its real position during sunset due to Earth's atmospheric refraction. [2] In 1998, NASA astrophysicist Yu Wang from the Jet Propulsion Laboratory for the first time proposed to use the Earth as an atmospheric lens. [2] Wang suggests in his paper that: [3] ''If we could build a space telescope ...
