Space Exploration Merit Badge (WORKSHEET & REQUIREMENTS)

The Space Exploration Merit Badge is a great way to learn about the science of space exploration. Whether you are a Scout hoping to earn the badge or a leader looking to teach it, here’s all you need to know about the Space Exploration Merit Badge.


Before beginning, all Scouts must have a Merit Badge Blue Card as provided by the scout leader.

1. Explain the scientific principles involved in the exploration of space.

Space exploration is the process of probing the universe beyond the Earth’s atmosphere to gain a greater understanding of its composition, conditions, and features. The scientific principles involved with the exploration of space include gravitational forces, rocket propulsion, orbital mechanics, and much more.

2. Do the following:

a. Make a list of seven professionals involved in space exploration, including their job titles and descriptions.

• Astronomer: A scientist who studies the stars, galaxies, black holes, and other heavenly bodies
• Aerospace Engineer: An engineer who specializes in the design, development, and testing of aircraft and spacecraft
• Astrophysicist: A scientist who studies the physical and chemical properties of matter in space
• Spacecraft Operator: A professional who is responsible for the operation and maintenance of spacecraft
• Astronaut: An individual who travels to space and performs experiments and other tasks in a spacecraft
• Spacecraft Designer: A professional who designs and develops spacecraft for various purposes
• Data Analyst: A professional who is responsible for analyzing and interpreting data gathered from various space exploration missions

b. Using a model or drawing explain the parts of a rocket and their functions.

A rocket consists of several main parts.

• The nose cone is the pointed tip of the rocket, which helps to reduce drag and keep the rocket on its trajectory.
• The payload bay is the area of the rocket where the payload, or cargo, is carried.
• The engines are the components that provide the thrust needed to propel the rocket.
• The fuel tanks are the containers that store the fuel used in the rocket’s engines.
• The fins are the stabilizing wings of the rocket that help to keep it upright and stable in flight.
• The launch tower is the structure that provides the rocket with the necessary support during launch.
• The booster rockets are additional rocket engines that are used to provide additional thrust to the rocket when it needs it.

3. Explain the purpose of a sounding rocket and its components.

A sounding rocket is a type of rocket used to conduct research in the Earth’s upper atmosphere. It consists of several components, including a payload module, a solid-fuel rocket motor, and a guidance system. The purpose of a sounding rocket is to gather data from the upper atmosphere, such as temperature, pressure, and other atmospheric characteristics. The payload module carries instruments and scientific experiments to be deployed and conducted in the upper atmosphere. The solid-fuel rocket motor provides the thrust needed to propel the rocket to the upper atmosphere. The guidance system helps the rocket stay on its trajectory.

4. Describe the role of the International Space Station.

The International Space Station (ISS) is a research and observation facility that orbits the Earth at an altitude of about 400 km (250 mi). It is a collaborative effort between the United States, Russia, Canada, Japan, and the European Space Agency. The ISS provides an opportunity to conduct scientific experiments in a zero-gravity environment, allowing researchers from around the world to gain a better understanding of many scientific disciplines, such as biology, chemistry, and medicine. The ISS is also used to observe the Earth and its environment, providing valuable data to scientists on a variety of topics, including climate change, air pollution, and the effects of space radiation on human health.

5. Name five major accomplishments in space exploration.

• The first spacecraft to explore Mars (Mariner 4, 1964)
• The first spacecraft to land on the Moon (Apollo 11, 1969)
• The first space station (Salyut 1, 1971)
• The first international space laboratory (Mir, 1986)
• The first interplanetary probe to reach another star (Voyager 1, 1977)


The Space Exploration Merit Badge is a great way to learn about the science behind space exploration. With these requirements and activities, Scouts can gain an understanding of the principles involved in space exploration, the components of a rocket, and the accomplishments of space exploration.
