A gravity assist, gravity assist maneuver, swing-by, or generally a gravitational slingshot in orbital mechanics, is a type of spaceflight flyby which makes use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense.
The moon’s gravity slightly bent Juice’s path so it received a much larger gravity assist from Earth. The flyby of Earth reduced Juice’s speed by 10,737 miles per hour (4.8 kilometers per ...
Gravity turn of the Space Shuttle. A gravity turn or zero-lift turn is a maneuver used in launching a spacecraft into, or descending from, an orbit around a celestial body such as a planet or a moon. It is a trajectory optimization that uses gravity to steer the vehicle onto its desired trajectory.
The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated by NASA (the National Aeronautics and Space Administration). Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. [ 1 ]
The positioning had to be precise. The shuttle's nose was raised 200 feet into the night sky so that the rudder could clear 80 feet of space. Endeavour was then turned 17 degrees clockwise to ...
Ace Combat 5: The Unsung War is a video game that features a mission requiring a rocket sled site to be defended from an air raid during a launch. Mobile Suit Gundam: Char's Counterattack shows a rocket sled was used to assist in the takeoff of the civilian space shuttle.
The Air Force expected to use the Space Shuttle to launch large satellites, and required it to be capable of lifting 29,000 kg (65,000 lb) to an eastward LEO or 18,000 kg (40,000 lb) into a polar orbit. The satellite designs also required that the Space Shuttle have a 4.6 by 18 m (15 by 60 ft) payload bay.
Apollo 13 was slated to be the third landing on the moon after Apollo 8 (1968) and Apollo 12 (1969). Launched on April 11, 1970, the crew was led by commander Lovell, along with command module ...
