=Costs of Space Travel=

Space travel not only costs billions of dollars, it also costs life. During a pre-flight test, fire erupted and killed three American astronauts, Gus Grissom, Ed White and Roger Chaffee. Another disaster happened on January 28, 1986, when the space shuttle Challenger blew up just one minute after take off. All seven crew members died. In 2003, the space shuttle Columbia fell apart over Texas. All seven crew members died in that disaster as well.

We have to explore space, but we must not forget the cost of our success. We must not forget the astronauts that died. We must make our explorations safe.
