B Correct answer
Explanation

The Space Launch System (SLS) is a super heavy-lift launch vehicle that is being developed by NASA to launch the Orion spacecraft and other payloads into space. The SLS will be the most powerful rocket ever built, and it will be used to launch the Artemis missions to the Moon and Mars.

Multiple choice

Which of the following is not a potential application for solar sails in space?

  1. Interstellar travel

  2. Solar system exploration

  3. Earth observation

  4. Communication satellites
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Solar sails are a type of spacecraft propulsion system that uses the pressure of sunlight to propel a spacecraft. Solar sails are lightweight and have a large surface area, which makes them ideal for interstellar travel and solar system exploration. However, solar sails are not suitable for Earth observation or communication satellites because they require a constant source of sunlight to operate.

Multiple choice
