23. Robots in Space Exploration

According to the essay, what is the primary reason robots are used in space exploration?
1. They are less expensive to build than telescopes.
2. They can travel to places that are currently too dangerous for humans.
3. They are more creative than human scientists at analyzing data.
4. They can function without any instructions from Earth.
The main job of rovers like Curiosity and Perseverance on Mars is to:
1. Map the surface and measure magnetic fields.
2. Search for signs of life and understand the planet's climate history.
3. Prepare the environment for future human inhabitants.
4. Travel to the edge of the solar system and send back data.
How is an unmanned probe different from a rover?
1. A probe is designed to study rocks, while a rover studies atmospheres.
2. A probe is sent to moons, while a rover is sent to planets.
3. A probe typically does not land, while a rover drives on a surface.
4. A probe is powered by solar energy, while a rover uses nuclear power.
Based on the essay, what is one key function of probes like Voyager?
1. They act as robotic geologists by drilling into soil.
2. They send back information from the edge of our solar system.
3. They search for water and air on other planets.
4. They carry astronauts to distant moons.
The essay states that by doing "the difficult groundwork," robots are:
1. Replacing the need for human astronauts entirely.
2. Building structures on the Moon and Mars.
3. Paving the way for future human missions.
4. Competing with other countries to claim new territory.
