Question 1

True or false: Cassini carried a probe named Huygens that landed on Saturn's largest moon, Titan.

Accepted Answer

True. The Huygens probe, built by ESA, parachuted onto Titan's surface in 2005, revealing lakes of methane.

Question 2

True or false: Cassini was the first spacecraft to visit Saturn, arriving in 2004.

Accepted Answer

False. Pioneer 11 flew by in 1979, and Voyager 1 and 2 in the 1980s. Cassini was the first orbiter, not first visitor.

Question 3

True or false: Cassini's mission lasted only 4 years before it ran out of fuel.

Accepted Answer

False. Cassini operated for 13 years (2004-2017), far exceeding its planned 4-year primary mission due to efficient fuel use.

Question 4

True or false: Cassini's final maneuver was a controlled crash into Saturn's atmosphere to avoid contaminating moons.

Accepted Answer

True. In 2017, Cassini plunged into Saturn to protect potential life on Enceladus or Titan from Earth microbes.

Question 5

True or false: Cassini's power came from large solar panels, as it was close enough to the Sun.

Accepted Answer

False. Saturn is far from the Sun, so Cassini used radioisotope thermoelectric generators (RTGs) powered by plutonium.

Question 6

True or false: Cassini discovered geysers of water ice erupting from Saturn's moon Enceladus.

Accepted Answer

True. In 2005, Cassini found plumes of water vapor and ice shooting from Enceladus' south pole, hinting at a subsurface ocean.

Question 7

True or false: Cassini discovered that Saturn's rings are older than the solar system itself.

Accepted Answer

True. Actually, Cassini data suggests Saturn's rings are surprisingly young, only about 100-400 million years old.

Question 8

True or false: Cassini discovered a massive hexagonal storm at Saturn's north pole.

Accepted Answer

False. The hexagon was first spotted by Voyager in the 1980s; Cassini provided detailed images but didn't discover it.
