The thrust-to-weight ratio is usually calculated from initial gross weight at sea level on earth [6] and is sometimes called thrust-to-Earth-weight ratio. [7] The thrust-to-Earth-weight ratio of a rocket or rocket-propelled vehicle is an indicator of its acceleration expressed in multiples of earth's gravitational acceleration, g 0 .

Mass includes 100 tons of remaining propellant. [6] Mass is a rough estimate. Ship 28 and Ship 29 flew long Suborbital flights, however both demonstrated that Starship can reach LEO. Suborbital: In development 2020–2024 Space Shuttle orbiter: 122,683 kg (270,470 lb) Space Shuttle Atlantis on STS-117, the heaviest flight of the Space Shuttle ...
The Space Shuttle external tank (ET) carried the propellant for the Space Shuttle Main Engines, and connected the orbiter vehicle with the solid rocket boosters. The ET was 47 m (153.8 ft) tall and 8.4 m (27.6 ft) in diameter, and contained separate tanks for liquid oxygen and liquid hydrogen.
Delta-v in feet per second, and fuel requirements for a typical Apollo Lunar Landing mission.In astrodynamics and aerospace, a delta-v budget is an estimate of the total change in velocity (delta-v) required for a space mission.
In a spacecraft, the destination is usually an orbit, while for aircraft it is their landing location. A higher mass fraction represents less weight in a design. Another related measure is the payload fraction, which is the fraction of initial weight that is payload. It can be applied to a vehicle, a stage of a vehicle or to a rocket propulsion ...
