[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 ...
"Sky Lift" is a science fiction short story by Robert A. Heinlein, first published 1953. In the story, a torchship pilot lights out from Earth orbit to Pluto on a mission to deliver a cure to a plague ravaging a research station. [12] Tau Zero, a hard science fiction novel by Poul Anderson, has a spaceship using a constant acceleration drive.
Starship flight test 4 was the fourth flight test of the SpaceX Starship launch vehicle. SpaceX performed the flight test on June 6, 2024. The prototype vehicles flown were the Starship Ship 29 upper-stage and Super Heavy Booster 11 .
When stacked and fully fueled, Starship has a mass of approximately 5,000 t (11,000,000 lb), [c] a diameter of 9 m (30 ft) [17] and a height of 121.3 m (398 ft). [6] The rocket has been designed with the goal of being fully reusable to reduce launch costs; [18] it consists of the Super Heavy booster and the Starship upper stage [19] which are powered by Raptor and Raptor Vacuum engines.
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.
Two NASA astronauts have spent nearly three months waiting aboard the International Space Station after their Boeing spacecraft encountered problems on its journey into orbit.

A space vehicle's flight is determined by application of Newton's second law of motion: =, where F is the vector sum of all forces exerted on the vehicle, m is its current mass, and a is the acceleration vector, the instantaneous rate of change of velocity (v), which in turn is the instantaneous rate of change of displacement.
