SEATTLE (AP) -- The finalists in a contest to be sent into space as part of Seattle Center's 50th anniversary celebration are in Seattle this week.
The final phase of the contest begins Monday morning. The finalists will each face three challenges before the winner is announced on Wednesday.
About 50,000 people sent in videos to enter the contest. Five finalists were chosen from that group.
Astronaut Buzz Aldrin will announce the winner of the sub-orbital trip into space at a ceremony at the Space Needle after the third challenge.
