Quiz Answer Key and Fun Facts

1. One of the two Mars Rovers that landed on the surface of the red planet in January 2004 is 'Spirit'. What's the name of the other one?

Answer: Opportunity

Spirit and Opportunity were clear examples of the fact that science and innovation are by no means cold or purely rational endeavors, but carry with them deep aspirations of humanity.

2. What was the main purpose of the Mars rovers?

Answer: Help scientists track the existence of water on the planet

Although the main aim of the two rovers was to track whether water exists or had existed on Mars, and in what form, they also did other kinds of testing that provided scientists with crucial information about the planet. These include their functions to pave the way for human exploration of Mars and determine whether life ever existed on the planet.

3. Who was responsible for launching the two rovers and controlling the project?

Answer: JPL (Jet Propulsion Lab)

JPL is a laboratory of NASA, and was established at California Institute of Technology in the 1930s. They were the primary institution responsible for the two rovers, but they also run many other space projects, including the Cassini and Voyager missions.

4. What happened to Spirit in May 2009, resulting in it becoming a stationary rover (a striking example of an astronomical oxymoron)?

Answer: It became stuck in soft soil

After attempting for about 9 months to get the rover moving again, JPL finally gave up and resigned themselves to use it as a stationary observation and testing station.

5. With such delicate equipment on board, how did the two rovers make it safely onto the surface of Mars?

Answer: The rover was folded up in a lander with a protective heat shield

Landing the rovers was a crucial and delicate operation, and could have wrecked the whole project if it had gone wrong!

6. For how long did scientists originally believe the two rovers would function?

Answer: Around 90 days

Spirit and Opportunity far exceeded their mission of 90 days, and as such fulfilled the optimism signified by their names. They were a great success story in the annals of space exploration.

7. What was the main source of energy that powers the two rovers?

Answer: Solar power

The large solar panels mounted on each of the rovers were one of their most characteristic features, but they're not ordinary. They had special sensors that detected the build up of dust, a great danger in the dusty Martian atmosphere. An electrical charge was used to get rid of dust that may have impeded the function of the solar panels.

Some of the instruments made use of radioactive sources for power.

8. How were the functions and movements of the two rovers controlled?

Answer: Antennae relaying long range radio signals

Not only were the operations controlled from Earth, but the rovers also sent their images and information back to Earth with these antennae.

9. How did the two rovers move about on the rocky surface of Mars?

Answer: On six wheels

The six free moving wheels on each vehicle are what allow the rovers to move about on the rough surface of Mars. Spirit's wheels have given some trouble however, and by 2009 only four of the six were operational.

10. What distance did Spirit cover, since 2004, before it became stuck in March 2010?

Answer: 7 kilometers, or 4.2 miles

Although it does not sound like a great distance, the 7 kilometers yielded much valuable information and many memorable images. Larger scale observations and mapping are handled by units orbiting Mars.
