Why is the Atlas V asymmetrical?
There was one booster on one side of the rocket, and two boosters on the other side. Further research revealed that the positioning for the booster was intentional. Which is odd, because off-setting the boosters will give more thrust to one side of the rocket, and in turn, end in a disaster!
Who invented the rocket engine?

How are rocket engines throttled?
Rockets can usually be throttled down to an exit pressure of about one-third of ambient pressure (often limited by flow separation in nozzles) and up to a maximum limit determined only by the mechanical strength of the engine.
Is a rocket symmetrical?
Most rockets are symmetric about a line from the tip of the nose to the center of the nozzle exit. We will call this line the roll axis and motion about this axis is called a rolling motion. Because the rocket is symmmetric about the roll axis, engineers call this configuration axisymmteric.
Is a rocket faster than a jet?
Rockets definitely fly faster than jets. A supersonic airplane can fly faster than the speed of sound (1,236 kmh or 768 mph). The SR-71 Blackbird holds the record for fastest jet, flying at 3,418 kmh (2,124 mph). Rockets have to reach that speed to escape Earth’s gravitational pull to get to space.
Has there ever been a dog in space?
Dogs. A number of dogs have gone into space under the former Soviet Union. The most well-known was Laika in 1957. Though other dogs had been launched into space before her, Laika is famous for being the first animal to orbit the Earth.
How does a rocket fly?
In rocket flight, forces become balanced and unbalanced all the time. A rocket on the launch pad is balanced. The surface of the pad pushes the rocket up while gravity tries to pull it down. As the engines are ignited, the thrust from the rocket unbalances the forces, and the rocket travels upward.
Is the Raptor engine Throttleable?
The testing of the SN8 vehicle is the next step in SpaceX’s Starship development program, with three Raptor engines mounted at the base of the vehicle. The three throttleable Raptor engines, each capable of producing up to 500,000 pounds of thrust, will allow SpaceX to attempt more ambitious Starship test flights.
Why do rockets spin in space?
In flight, the fins of the rocket produce aerodynamic forces. These forces are applied at the center of pressure of the rocket which is some distance from the rocket cg and produce torques (or moments) about the principal axes. The torques cause the rocket to rotate.
What type of missile is Atlas?
Atlas (rocket family) Atlas is a family of American missiles and space launch vehicles. The original Atlas missile was designed in the late 1950s and produced by the Convair Division of General Dynamics, to be used as an intercontinental ballistic missile (ICBM).
What kind of engines are used in Atlas V rockets?
Each Atlas V rocket consists of two main stages. The first stage is powered by a Russian RD-180 engine manufactured by RD Amross and burning kerosene and liquid oxygen. The Centaur upper stage is powered by one or two US RL10 engine(s) manufactured by Aerojet Rocketdyne and burning liquid hydrogen and liquid oxygen.
How did NASA use the Atlas rocket in space?
NASA used them in the Ranger program to obtain the first close-up images of the surface of the Moon and for Mariner 2, the first spacecraft to fly by another planet. Each of the Agena target vehicles used for the later space rendezvous practice missions of Gemini was launched on an Atlas rocket.
What is the difference between Atlas II and Redstone rocket?
From 1962 to 1963, Atlas boosters launched the first four American astronauts to orbit the Earth whereas Redstone preceded Atlas with two sub-orbital launches. Various Atlas II models were launched 63 times between 1991 and 2004.
