For many decades, humans have dreamed of exploring beyond the solar system to the distant planets and stars. The space technology for doing this has until recently been confined to the realm of science fiction. However, developments in science are now suggesting that such a technology is feasible in practice as well as in principle. Therefore, it is only a matter of time before humans realise their dream and are able to explore outer space. Which of the following is an assumption underlying the above argument?
A The only obstacle to space exploration is inadequate space technology.
B Space exploration is worthwhile and will solve many problems.
C People would be willing to see governments financing space exploration.
D Science will succeed in developing risk-free space exploration.
E Science fiction has little basis in real science.
