Mars in coming future by humans
first human mission to Mars can be made much safer.
Should we spend billions of dollars and risk the lives of the astronauts on a dangerous, 18-month mission to an uninhabitedplanet, just to look around and then come back again?
"Yes," say the enthusiasts. "Humans are naturally adventurous. Without people willing to take a chance, to explore new places, new ideas and new ways of doing things, we would all be living in caves and eating nuts and berries."
"No," say the doubters. "The money would be better spent on medical research and solv
ing everyday problems here on Earth. What is the point of going to a dead planet. What's the point of space travel?"
Take a look at some of the comments the BBC received when they raised the question: Should we send humans to Mars?
In groups, prepare a presentation in support of one of the following positions:
- 1) Humans should travel to Mars as soon as they can.
- 2) Manned space travel is a waste of time and money.
Take a vote before preparing the presentations and after. Discuss any shift in thinking that takes place. Investigate why your classmates changed their minds. Did it happen because of their own efforts to find good arguments or because of what they heard from others? What does this tell you?
Life on Earth is at the ever-increasing risk of being wiped out by a disaster such as sudden global warming,
nuclear war, a genetically engineered virus or other dangers ... I think the human race has no future if it doesn't go into space.
" Another of his famous quotes reiterates his position that we need to get off the planet relatively soon.
"I don't think the human race will survive the next 1,000 years unless we spread into space."
