The Future of Space Travel May Not Lie with Humans

question 9

Multiple Choice

The future of space travel may not lie with humans, but with robots. At the dawn of the space age, space travel required human astronauts-they were simply more capable than robots. But humans developed technology that steadily made robots more attractive. Astronauts have to breathe, eat, and drink to keep going. But robots can travel to the ends of the solar system free of such constraints. They can do more, go further, and because they don't require costly life-support systems, they can do it all more often. Of course, they still require human direction. Nevertheless, we should all look for more robotic space travelers in the future.
Which of the following is true according to information found in the passage?

• A)Humans were better space travelers than robots in the early days of space exploration.
• B)Robots are more expensive to send into space than humans.
• C)Humans developed the technology that is needed to breathe, eat, and drink in space
• D)Robots that are used to explore space don't need guidance from humans.
