Question

What does the space shuttle use to place a satellite into space? A) liquid-fuel tank B) booster rocket C) mechanical arm D) cargo bay

Short answer

C) mechanical arm

Step-by-step solution

Understand the Purpose of Each Option

Let's understand the purpose of each component listed in the options: - A liquid-fuel tank stores the fuel used for propulsion. - A booster rocket provides the thrust needed to lift the space shuttle off the ground and move it into orbit. - A mechanical arm is used for manipulation tasks in space, like placing or retrieving satellites. - A cargo bay is used to store satellites and other cargo during the journey.

Identify the Component Used for Placing Satellites in Space

Determine which component is specifically used for placing satellites into space: The mechanical arm is used by astronauts to deploy or position satellites in their designated orbits once the shuttle is already in space. It acts as a robotic arm that handles the satellites precisely.

Confirm the Answer

Since the question asks for the tool that places satellites into space from the shuttle, and the mechanical arm is responsible for the deployment and positioning of satellites once in orbit, the correct answer is 'mechanical arm'.

Key concepts

Mechanical Arm

A mechanical arm, in the context of a space shuttle, is an advanced robotic tool primarily used for complex tasks in space. This arm, often referred to as the "Canadarm," was a critical invention used in NASA's space shuttle program. The mechanical arm functions effectively like an extension of an astronaut's own arm, providing them with the ability to perform actions outside the space shuttle.

The operation of the mechanical arm is controlled by astronauts from within the shuttle. They can direct its movements precisely to grip, lift, and position satellites in their proper orbits. This system allows astronauts to work on tasks that would otherwise be impossible in the vacuum and weightlessness of space.

• The arm can reach out of the shuttle's cargo bay to deploy and retrieve satellites.
• It provides a stable base for astronauts working on external tasks or repairs.
• The mechanical arm contributes to the mission's success by enhancing the shuttle's operational capabilities.

Satellite Placement

Satellite placement involves several critical steps to ensure a satellite functions properly in its designated orbit. Once the space shuttle reaches the correct altitude above Earth, the satellite deployment process begins. Using the space shuttle's mechanical arm, astronauts carefully position the satellite for deployment.

The precise placement of a satellite is vital; even a small miscalculation can result in incorrect orbit insertion, leading to mission failure. As part of the placement process, astronauts:

• Use the mechanical arm to lift the satellite out of the cargo bay.
• Position it at the calculated point in space.
• Ensure it is oriented correctly for its intended mission.
• Release the satellite smoothly to avoid disruptions in trajectory.

This deployment must be conducted with perfect timing and accuracy, often aided by advanced computer systems and detailed orbital calculations to guarantee success.

Space Shuttle Components

The space shuttle is composed of various components, each serving a distinct purpose in the shuttle's mission to space. These parts must work together seamlessly to facilitate a successful journey.

Key components include:

• Liquid-fuel tanks: Essential for storing and burning the fuel that powers the shuttle into orbit.
• Booster rockets: Provide the necessary thrust to escape the gravitational pull of Earth.
• Cargo bay: Houses satellites and other mission-related equipment during the trip.
• Mechanical arm: Used in-space for deploying satellites and conducting other tasks requiring precision.

Each component contributes its specific function, ensuring the safety and efficacy of space missions. A deep understanding of these components is crucial for anyone interested in the mechanics and operations of space travel.
