People from 50 countries are celebrating space exploration as part of World Space Week – from October 4 to 10, 2003. Lance Bass, member of the pop group NSYNC, is the event’s youth spokesman, and will be traveling to various schools in the US to help build young students’ enthusiasm for space. Several other events are planned for this week, including a question and answer session with the astronauts on board the International Space Station. The first World Space Week was declared by the United Nations in 1999.
