Space Exploration Technologies starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Space Exploration Technologies.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A satellite completes one orbit around Earth in 24 hours. What type of orbit is this?
Describe one reason why space suits are essential for astronauts working outside a spacecraft.
Describe one way in which space exploration technologies have benefited life on Earth.
Describe the main function of a launch vehicle in space missions.
Explain the main difference between a space probe and a satellite.
Explain why communication with deep space probes can take several minutes or hours.
A Mars lander uses a combination of parachutes and retro-rockets to slow its descent through the Martian atmosphere. Explain why both systems are necessary, considering the properties of Mars' atmosphere.
A spacecraft is traveling to Jupiter and needs to minimize fuel consumption. Explain how the concept of gravitational slingshot (gravity assist) is used to increase the spacecraft's speed, and describe the physics principle that allows this maneuver to work.
