Orbital space stations
• Discuss in small groups the advantages
and disadvantages of a space holiday on
an orbiting space station for tourists.
• List the things they would want to know,
e.g. cost, duration, experiences, etc.
• Set criteria that would persuade you to go
on such a holiday.
Homework
• Prepare five
questions to ask
me on my next
mission.
• What do you think
the answers would
be?
