October Sky is a 1999 American biographical drama film directed by Joe Johnston, and starring Jake Gyllenhaal, Chris Cooper, Chris Owen, and Laura Dern.The screenplay by Lewis Colick, based on the book of the same name, tells the story of Homer H. Hickam Jr., a coal miner's son who was inspired by the launch of Sputnik 1 in 1957 to take up rocketry against his father's wishes and eventually ...
In a MIRV, the main rocket motor (or booster) pushes a "bus" into a free-flight suborbital ballistic flight path. After the boost phase, the bus maneuvers using small on-board rocket motors and a computerized inertial guidance system. It takes up a ballistic trajectory that will deliver a re-entry vehicle containing a warhead to a target and ...
Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets, satellites, and other spacecraft.
A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth , it must be on a free trajectory which has an altitude at perigee (altitude at closest approach) around 80 kilometers (50 mi); this is the boundary of ...
This sends him on a quest to locate a new rocket being built using that plastic. ... he seeks the rocket (whose name, 00000, should clue you in to its inherent value), then, finally, he descends ...
Back to the mistaken notion: If you fire your rifle at a 10 degree angle of fire, you could achieve the same range by firing the rifle at an 80 degree angle, but have a plunging trajectory rather than a more direct trajectory, though they would both be parabolas. Of course, this all neglects air resistance, but that isn't covered in this section.
Vertical landing rocket depicted in 1951 comic Rocket Ship X. Vertical landing of spaceships was the predominant mode of rocket landing envisioned in the pre-spaceflight era. Many science fiction authors as well as depictions in popular culture showed rockets landing vertically, typically resting after landing on the space vehicle's fins. This ...
