Question 1

True or false: Mars Pathfinder used a parachute and airbags to land safely on Mars.

Accepted Answer

True. It used a parachute, then retro-rockets, and finally giant airbags that bounced the lander to a stop—a novel technique.

Question 2

True or false: Mars Pathfinder was the first mission to deploy a rover on Mars.

Accepted Answer

True. Pathfinder's Sojourner rover was the first successful rover on Mars, preceding Spirit and Opportunity by seven years.

Question 3

True or false: Pathfinder discovered evidence of ancient microbial life on Mars.

Accepted Answer

False. Pathfinder's Sojourner rover found evidence of past water, but not microbial life. Claims of ancient Martian life are primarily associated with the 1996 announcement about meteorite ALH84001, which remains controversial.

Question 4

True or false: The Sojourner rover was about the size of a microwave oven.

Accepted Answer

True. Sojourner was compact—65 cm long, 48 cm wide, and 30 cm tall—roughly the size of a microwave, weighing just 11.5 kg.

Question 5

True or false: The Sojourner rover was powered by a small nuclear battery.

Accepted Answer

False. Sojourner used solar panels for power, not nuclear. Its batteries stored energy for nighttime operations.

Question 6

True or false: Pathfinder's landing site was named the Carl Sagan Memorial Station.

Accepted Answer

True. After landing on July 4, 1997, NASA renamed the landing site in honor of astronomer Carl Sagan, who died the previous year.

Question 7

True or false: Mars Pathfinder's mission lasted less than one Martian year.

Accepted Answer

True. Pathfinder operated for 83 sols (Martian days), far shorter than a Martian year (687 Earth days), ending due to battery failure.

Question 8

True or false: Pathfinder was the first spacecraft to orbit Mars before landing.

Accepted Answer

False. Pathfinder landed directly without orbiting. Earlier missions like Viking 1 and 2 had orbited before landing.
