  2. Space travel under constant acceleration - Wikipedia

    en.wikipedia.org/wiki/Space_travel_under...

    In the Known Space universe, constructed by Larry Niven, Earth uses constant acceleration drives in the form of Bussard ramjets to help colonize the nearest planetary systems. In the non-known space novel A World Out of Time , Jerome Branch Corbell (for himself), "takes" a ramjet to the Galactic Center and back in 150 years ships time (most of ...

  3. Delta-v budget - Wikipedia

    en.wikipedia.org/wiki/Delta-v_budget

    To reach the initial low Earth orbit of the International Space Station of 300 km (now 400 km), the delta-v is over six times higher, about 9.4 km/s. Because of the exponential nature of the rocket equation the orbital rocket needs to be considerably bigger. Launch to LEO—this not only requires an increase of velocity from 0 to 7.8 km/s, but ...

  4. Earth's orbit - Wikipedia

    en.wikipedia.org/wiki/Earth's_orbit

    [nb 1] Earth's orbital speed averages 29.78 km/s (19 mi/s; 107,208 km/h; 66,616 mph), which is fast enough to cover the planet's diameter in 7 minutes and the distance to the Moon in 4 hours. [3] The point towards which the Earth in its solar orbit is directed at any given instant is known as the "apex of the Earth's way". [4] [5]

    Minecraft Earth was an augmented reality and geolocation-based sandbox game developed by Mojang Studios and Blackbird interactive and published by Xbox Game Studios. A spin-off of the video game Minecraft , it was first announced in May 2019, and was available on Android and iOS .

  6. Orbital spaceflight - Wikipedia

    en.wikipedia.org/wiki/Orbital_spaceflight

    To reach orbit, the rocket must impart to the payload a delta-v of about 9.3–10 km/s. This figure is mainly (~7.8 km/s) for horizontal acceleration needed to reach orbital speed, but allows for atmospheric drag (approximately 300 m/s with the ballistic coefficient of a 20 m long dense fueled vehicle), gravity losses (depending on burn time ...

  7. Far Lands or Bust - Wikipedia

    en.wikipedia.org/wiki/Far_Lands_or_Bust

    Far Lands or Bust (abbreviated FLoB) is an online video series created by Kurt J. Mac in which he plays the video game Minecraft.The series depicts his journey to the "Far Lands", a distant area of a Minecraft world in which the terrain generation does not function correctly, creating a warped landscape.

  8. Parker Solar Probe - Wikipedia

    The velocity decreases by 2.9 km/s to 26 km/s (red circle), shifting the spacecraft to a new orbit closer to the Sun. Within each orbit of the Parker Solar Probe around the Sun, the portion within 0.25 AU is the Science Phase, in which the probe is actively and autonomously making observations.

  9. Orders of magnitude (speed) - Wikipedia

    Average walking speed—below a speed of about 2 m/s, it is more efficient to walk than to run, but above that speed, it is more efficient to run. 2.39: 8.53: 5.35: 7.97 × 10 −9: World record time 50m freestyle swim 5.78: 20.81: 12.93: 1.928 × 10 −8: World record time marathon [13] 6–7: 20–25: 12–15: 1.8–2.3 × 10 −8 ...
