TO WHAT EXTENT DO YOU AGREE OR DISAGREE? Among all the achievements that veritably defined humanity in the 20th century, few were as enthusiastically embraced and celebrated as space travel. However, in recent years, the public has become much less thrilled about the achievements of space exploration. A school of thought holds that the money spent on expeditions to other planets is hard to justify when there are many other issues on earth that call for prodigious financial resources. I strongly disagree with this thinking.
