Exploring Comets: The Rosetta Mission

The video discusses the exploration of comets, focusing on the Rosetta mission by the European Space Agency. It highlights the challenges faced during the mission, including launch failures and the need to find a new comet target. Rosetta's journey involves complex maneuvers and innovative solar technology. The mission aims to study Comet 67P to understand the solar system's formation. Rosetta's lander, Filet, will analyze the comet's surface, providing insights into its composition and changes as it approaches the sun.

What did the Giotto mission prove about comets?

• They contain water.

• They have no atmosphere.

• They are made of metal.

• They have complex organic molecules.

Why was the Rosetta mission initially delayed?

• Due to a lack of funding.

• Because of a software problem in the Arian 5 booster.

• The comet was too far away.

• The spacecraft was not ready.

What was the new target comet for the Rosetta mission?

• Comet Halley

• Comet Botanin

• Comet 67P/Churyumov-Gerasimenko

• Comet Lieutenant

How does Rosetta gain extra acceleration to reach its target?

• By using additional rocket boosters.

• Through swing-by maneuvers past Earth and Mars.

• By reducing its weight.

• By using solar sails.

What is unique about Rosetta's power source?

• It is powered by solar generators.

• It uses nuclear power.

• It uses wind energy.

• It is powered by fossil fuels.

What is the purpose of the Philae lander?

• To orbit the comet.

• To collect samples from the comet's surface.

• To photograph the comet.

• To communicate with Earth.

What will Rosetta do after the Philae lander detaches?

• Continue orbiting and observing the comet.

• Land on the comet itself.

• Return to Earth.

• Move to another comet.
