1. Understanding Space Shuttle Speed

1.1 What is Orbital Velocity?

Orbital velocity is the speed needed to maintain a stable orbit around a celestial body. For a space shuttle orbiting Earth, this speed balances the gravitational pull of the Earth with the inertia of the shuttle’s motion. The orbital velocity depends on the altitude of the orbit; the lower the orbit, the faster the required speed.

1.2 How Fast Did Space Shuttles Typically Travel?

The space shuttle typically traveled at speeds of around 17,500 miles per hour (28,000 kilometers per hour) in low Earth orbit (LEO). According to NASA, this speed allowed the shuttle to circle the Earth approximately every 90 minutes.

1.3 Factors Affecting the Speed of a Space Shuttle

Several factors affect the speed of a space shuttle, including:

• Altitude: Lower orbits require higher speeds.
• Atmospheric Drag: Even in the upper atmosphere, drag can slow the shuttle down, requiring periodic adjustments.
• Mission Objectives: Different missions may require slightly different orbital altitudes and speeds.

1.4 Comparison with Other Spacecraft Speeds

1.5 The Role of Propulsion Systems in Achieving Speed

The Space Shuttle Main Engines (SSMEs), in conjunction with the Solid Rocket Boosters (SRBs), provided the initial thrust to lift the orbiter off the ground. After the SRBs were jettisoned, the SSMEs continued to accelerate the shuttle to orbital velocity. The engines could burn a half-million gallons of liquid propellant in 8.5 minutes, generating over 37 million horsepower.

2. The Science Behind Space Shuttle Travel

2.1 Newton’s Laws of Motion and Space Travel

Newton’s laws of motion are fundamental to understanding space travel:

• First Law (Inertia): An object in motion stays in motion unless acted upon by an external force.
• Second Law (F=ma): Force equals mass times acceleration. More force or less mass results in greater acceleration.
• Third Law (Action-Reaction): For every action, there is an equal and opposite reaction. This is how rocket propulsion works.

2.2 How Do Space Shuttles Achieve Orbit?

Space shuttles achieve orbit by accelerating to orbital velocity and reaching a specific altitude. They use powerful engines to overcome Earth’s gravity and aerodynamic drag. Once in orbit, the shuttle maintains its speed and altitude through periodic adjustments.

2.3 The Importance of Gravity in Space Travel

Gravity plays a crucial role in space travel. It keeps the shuttle in orbit around the Earth. The shuttle’s speed must be high enough to counteract gravity, preventing it from falling back to Earth.

2.4 Understanding Thrust and Acceleration

Thrust is the force that propels the space shuttle forward, generated by its engines. Acceleration is the rate at which the shuttle’s speed changes. The higher the thrust and the lower the mass, the greater the acceleration.

2.5 The Effects of Vacuum and Microgravity on Speed

In the vacuum of space, there is no air resistance to slow the shuttle down. This allows the shuttle to maintain its speed with minimal energy expenditure. Microgravity affects the shuttle’s systems and the astronauts onboard, requiring specific design considerations and operational procedures.

3. Space Shuttle Components and Their Contribution to Speed

3.1 The Orbiter: Brains and Heart of the Space Shuttle

The orbiter is the main component of the space shuttle, housing the crew, cargo bay, and main engines. It is about the same size and weight as a DC-9 aircraft and contains the pressurized crew compartment, which can carry up to seven crew members.

3.2 Main Engines: The Power Behind the Speed

The three Space Shuttle Main Engines (SSMEs) provide the thrust to lift the orbiter off the ground. They accelerate the shuttle from 3,000 mph to over 17,000 mph in just six minutes to reach orbit. These engines create a combined maximum thrust of more than 1.2 million pounds.

3.3 Solid Rocket Boosters (SRBs): Providing Initial Thrust

The Solid Rocket Boosters (SRBs) operate in parallel with the main engines for the first two minutes of flight. They provide the additional thrust needed for the orbiter to escape Earth’s gravitational pull. Each SRB provides a thrust of 2.65 million pounds at liftoff.

3.4 External Tank: Fueling the Journey

The External Tank (ET) contains the propellants used by the Space Shuttle Main Engines. It is the “gas tank” for the orbiter and provides structural support during launch. The tank is the only component of the Space Shuttle that is not reused.

3.5 The Role of Aerodynamics in High-Speed Flight

Aerodynamics play a crucial role in the space shuttle’s flight, especially during ascent and reentry. The shape of the orbiter is designed to minimize drag and control airflow.
