Question 1

True or false: The mission was named after the Rosetta Stone, which helped decipher Egyptian hieroglyphs.

Accepted Answer

True. The name symbolizes how Rosetta would help decipher the solar system’s origins, like the stone decoded ancient writing.

Question 2

True or false: Rosetta was the first mission to orbit a comet and deploy a lander.

Accepted Answer

True. It was indeed the first to orbit a comet and successfully deploy a lander, Philae, onto its surface.

Question 3

True or false: The Rosetta mission landed its Philae probe on a comet that had a rubber duck shape.

Accepted Answer

True. Comet 67P/Churyumov–Gerasimenko was famously shaped like a rubber duck, a surprising discovery from Rosetta images.

Question 4

True or false: Rosetta carried a small time capsule containing messages from Earth's leaders.

Accepted Answer

False. No time capsule was onboard; Rosetta had scientific instruments, not cultural artifacts. That’s a myth.

Question 5

True or false: Rosetta was powered by solar panels, even though it operated far from the Sun.

Accepted Answer

False. Rosetta used large solar panels, but they worked efficiently; the false part is implying they couldn’t—they did.

Question 6

True or false: Philae’s primary mission lasted only 60 hours due to its batteries dying.

Accepted Answer

True. Philae ran on non-rechargeable batteries and completed 60 hours of science before going silent, far from its planned months.

Question 7

True or false: Rosetta discovered water on the comet with the same isotopic ratio as Earth’s oceans.

Accepted Answer

False. The water on 67P had a different deuterium/hydrogen ratio, suggesting comets may not have delivered Earth’s water.

Question 8

True or false: Philae bounced twice before landing because its harpoons failed to fire.

Accepted Answer

True. Philae’s harpoons and thruster malfunctioned, causing it to bounce across the comet’s surface before settling.
