[1] [37]: 31 The solar shield is hexagonal, mounted on the Sun-facing side of the spacecraft, 2.3 m (7 ft 7 in) in diameter, [38] 11.4 cm (4.5 in) thick, and is made of two panels of reinforced carbon–carbon composite with a lightweight 11-centimeter-thick (4.5 in) carbon foam core, [39] which is designed to withstand temperatures outside the ...
The Alcubierre drive ([alkuˈβjere]) is a speculative warp drive idea according to which a spacecraft could achieve apparent faster-than-light travel by contracting space in front of it and expanding space behind it, under the assumption that a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.
However, it is not the fastest spacecraft to leave the Solar System. As of July 2023 [update] , this record is held by Voyager 1 , traveling at 16.985 km/s (61,146 km/h; 37,994 mph) relative to the Sun. [ 158 ] Voyager 1 attained greater hyperbolic excess velocity than New Horizons due to gravity assists by Jupiter and Saturn.
The spacecraft of George O. Smith's Venus Equilateral stories are all constant acceleration ships. Normal acceleration is 1 g, but in "The External Triangle" it is mentioned that accelerations of up to 5 g are possible if the crew is drugged with gravanol [11] to counteract the effects of the g-load.
An international flight crew set a new record for the fastest circumnavigation of the globe via the North and South Poles, clocking nearly six hours less than the previous mark. The 25,000-mile mission, named "One More Orbit," was led by Terry Virts, a former International Space Station commander, as a tribute to the Apollo 11 Moon landings. [3 ...
The spaceship’s propulsion system, for example, has been altered to increase the propellant volume by 25%. ... Instead, they will travel on a suborbital path, much like the Starship spacecraft ...
In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter (the combined center of mass) or, if one body is much more massive than the other bodies of the system combined, its speed relative to the center of mass of the most massive body.
Typically, this frame is fixed to the body with the greatest gravitational influence on the spacecraft, as this is the most relevant frame for most purposes. [66] Velocities in different frames of reference are not directly comparable; thus the matter of the "fastest spacecraft" depends on the reference frame used.
