Question 1

True or false: Viking 2 was the first spacecraft to successfully land on Mars.

Accepted Answer

False. That honor belongs to Viking 1, which landed on July 20, 1976, about six weeks before Viking 2.

Question 2

True or false: Viking 2's landing site was chosen partly because it was near the Martian north pole.

Accepted Answer

True. It landed at Utopia Planitia, about 4,000 km from the north pole, chosen for its relatively flat, safe terrain and potential for water ice nearby.

Question 3

True or false: Viking 2 took the first color photograph of the Martian surface.

Accepted Answer

False. Viking 1 took the first color photo just minutes after landing. Viking 2's first color images came a few hours later.

Question 4

True or false: Viking 2 landed on Mars in 1976 and operated for over three Earth years.

Accepted Answer

True. It landed on September 3, 1976, and transmitted data until April 11, 1980—nearly 3.5 Earth years, far exceeding its design life.

Question 5

True or false: Viking 2 found evidence of liquid water on Mars through its soil experiments.

Accepted Answer

False. No direct liquid water was found. Its biology experiments showed surprising chemical activity but no conclusive proof of life or liquid water.

Question 6

True or false: Viking 2’s biological experiments produced results that some scientists still debate today.

Accepted Answer

True. The Labeled Release experiment showed initial gas release mimicking life, but later tests suggested non-biological chemical reactions, sparking decades of debate.

Question 7

True or false: Viking 2's lander carried a seismometer that detected a marsquake.

Accepted Answer

True. It recorded one probable marsquake, but wind vibrations often masked seismic signals. It was the first detection of seismic activity on Mars.

Question 8

True or false: Viking 2's orbiter was intentionally crashed into Mars after its mission ended.

Accepted Answer

False. The orbiter was not crashed; it was deactivated after fuel depletion. The lander remained on the surface, not designed to move or crash.
