A gravity turn is commonly used with rocket powered vehicles that launch vertically, like the Space Shuttle. The rocket begins by flying straight up, gaining both vertical speed and altitude. During this portion of the launch, gravity acts directly against the thrust of the rocket, lowering its vertical acceleration.
ASTOS is a tool dedicated to mission analysis, Trajectory optimization, vehicle design and simulation for space scenarios, i.e. launch, re-entry missions, orbit transfers, Earth observation, navigation, coverage and re-entry safety assessments.
However, if a vehicle doesn’t come equipped with such features, then aftermarket forms of launch control can be purchased and installed. A common form of aftermarket launch control is commonly known as two-step rev limiting. A two-step rev limiter is a module that regulates the engines rpms for a controlled launch and optimal power settings.
By examining the results of the porkchop plot, engineers can determine when a launch opportunity exists (a 'launch window') that is compatible with the capabilities of a particular spacecraft. [2] A given contour, called a porkchop curve , represents constant C 3 , and the center of the porkchop the optimal minimum C 3 .
The SpaceLoft XL is a sounding rocket developed by private spaceflight company UP Aerospace. [2] The rocket is capable of lofting a 79 lb (36 kg) payload to a sub-orbital trajectory with an apogee of about 71.5 miles (115 km).

Lift and drag are the two components of the total aerodynamic force acting on an aerofoil or aircraft.. In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air.
Uber driver Derek Gooderham was zipping along on Interstate 83 when a wave of wood planks tumbled from the lumber truck, sliding down a hill and sweeping his car off the road. The scene was caught ...
