Rocket launch challenge

Your challenge is to make the rocket go as high as possible and launch a payload 400 km above the ground. You can change rocket parameters like mass, thrust and drag before launching to see how they affect how high the rocket goes. But, beware, too much thrust for too long and the rocket might explode in flight. This simulation is modelled on Rocket Lab’s Electron rocket and at about US$6 million per launch, failure is something Rocket Lab would never want to happen!

Top tip: When choosing a value in the slider boxes for mass, thrust or thrust time, click and drag to set an approximate value, then use the up and down arrows on your keyboard to reach your chosen value.

By the end of this activity, students should be able to:

• investigate how thrust, time of thrust and mass of a rocket can be changed to make a rocket go as high as possible

• explore how drag influences the height reached by a rocket

• explore how the speed and forces acting on a rocket change during a launch

• explore how the changing mass of a rocket (as propellant is used and ejected) affects the speed and height of a rocket.
