To hear her tell her inspiring story, check out this video (5:20) from National Geographic!

3) Build, launch, and recover a model rocket. Make a second launch to accomplish a specific objective. (Rocket must be built to meet the safety code of the National Association of Rocketry. See the “Model Rocketry” chapter.)
(If local laws prohibit the launching of model rockets, do the following activity: Make a model of a NASA rocket. Explain the functions of the parts. Give the history of the rocket.)

Launching a model rocket was one of the coolest experiences of my younger years, so I’m sure you’ll love it too! Before doing anything else though, make sure to review the safety code of the National Association of Rocketry. Rockets use explosions to propel themselves and can prove dangerous if you aren’t aware and prepared.

To find a safe and reliable rocket, I’d recommend checking out the Estes Journey Launch Set Rocket Kit, which is super similar to the one I used back in the day. Don’t forget the 2+ B6-4 engines as well. You’ll construct your rocket kit, light it, and watch the epic liftoff! But first, let’s identify and explain the key components of a model rocket:

  1. Body Tube: The body tube serves as the main structure of the rocket, providing stability and holding all other components together. It is typically made of lightweight materials like cardboard or plastic.
  2. Engine Mount: The engine mount houses the rocket engine securely within the body tube. It ensures proper alignment and retention of the engine during flight.
  3. Fins: Fins are the wing-like structures attached to the lower portion of the body tube. They stabilize the rocket during flight, keeping it on a straight trajectory. Fins can vary in number and shape, depending on the rocket design.
  4. Igniter: The igniter is a small device with a wire filament that ignites the rocket engine. When an electric current passes through the igniter, it ignites the rocket propellant, initiating the launch sequence.
  5. Launch Lug: The launch lug is a small tube or rod mounted on the side of the rocket. It guides the rocket along the launch rod or rail during liftoff and ensures a stable ascent.
  6. Nose Cone: The nose cone is the pointed tip at the top of the rocket. It reduces air resistance during flight and helps streamline the rocket’s trajectory.
  7. Payload: The payload is any equipment or payload bay on the rocket that carries scientific instruments, experiments, or other items into space. In model rockets, the payload is often a simple weight or a small capsule to simulate real space missions.
  8. Recovery System: The recovery system is essential for safely bringing the rocket back to the ground after its flight. Most model rockets use a parachute or streamer that deploys at the peak of the flight to slow the descent.
  9. Rocket Engine: The rocket engine is the heart of the rocket, containing the propellant that generates the thrust needed for liftoff. Rocket engines come in different sizes and power levels, depending on the desired flight characteristics.

With this knowledge, you can put your model rocket together with confidence and try out 2 launches. I’d recommend making your second objective something like tracking distance traveled from the launch point, time in air, or anything else you can think of measuring. Here’s a helpful video (6:22) to watch first:

This is one of the most fun requirements out there, so be sure to enjoy! You could even ask a parent or sibling to take a video so that you have great memories of your exciting launch. Have fun and be safe, Scout. Time to shoot for the stars! 😀

Discuss and demonstrate each of the following:
4a) The law of action-reaction
4b) How rocket engines work
4c) How satellites stay in orbit
4d) How satellite pictures of Earth and pictures of other planets are made and transmitted

Space exploration is only possible because of our advanced understanding of physics and technology. Don’t worry though, the requirements to earn this badge aren’t rocket science 😜. However, there are still some key terms to learn! Let’s delve into some of the fundamental concepts behind space missions:

1. The Law of Action-Reaction: The law of action-reaction, also known as Newton’s third law of motion, states that for every action, there is an equal and opposite reaction.

  • To demonstrate this, we can use a simple balloon rocket experiment. Inflate a balloon and then release it without tying the end. As the air escapes from the balloon in one direction, it propels the balloon forward in the opposite direction.
  • This showcases the principle that action (air escaping from the balloon) results in an equal and opposite reaction (balloon moving forward).

2. How Rocket Engines Work: Rocket engines operate on the principle of Newton’s third law. Fuel is combusted out the back of a rocket, propelling it forward.

  • A mixture of fuel and oxidizer burns inside the rocket engine’s combustion chamber, creating a high-speed exhaust of hot gases. The ejection of these gases in one direction causes the rocket to move in the opposite direction.
  • To demonstrate this, use a simple Diet Coke and Mentos rocket. Open a Diet Coke bottle over pavement, then place a Mento inside and turn it on its side. The Coke and Mentos will create a reaction, propelling diet coke out the back and the bottle forward. Warning: the reaction is fast and messy!
  • Check out the video (2:27) below for a neat demonstration! However, be sure to never do this around cars like them. That’s a huge safety hazard!

3. How Satellites Stay in Orbit: Satellites stay in orbit due to a delicate balance between the centrifugal force pulling them outward and the gravitational force pulling them inward. They’re essentially always falling, but the earth moves fast enough they never make contact!

  • To demonstrate this, use a string with a small weight (representing the satellite) attached to one end. Spin the weight around your head, and you’ll notice it stays in orbit due to the tension in the string providing the centripetal force, balancing the gravitational force.

4. How Satellite Pictures are Made and Transmitted: Satellite pictures of Earth and other planets are obtained using remote sensing technology. Sensors onboard satellites capture images in various wavelengths of light, such as visible, infrared, or microwave.

  • To demonstrate this, use a simple digital camera or smartphone to take pictures of objects, varying the settings to represent different wavelengths. Transmitting these images back to Earth involves radio frequency signals. You can simulate this by sending the pictures wirelessly to another device or computer.

There you have it! By exploring these concepts by looking them up in more detail, and by trying out a few simple demonstrations, you’ll gain a deeper appreciation for the science behind space exploration! Now that you have all the fundamentals down, next up we’ll be diving into how space exploration has actually been taking place. 🙂
