ORLANDO, Fla. (AP) - U.S. Sen. Bill Nelson wants to create five business enterprise zones around the country that would give tax breaks to space-related businesses.

The Florida Democrat is unveiling his plan Tuesday at the Kennedy Space Center.

Under the plan, space-related businesses would qualify for major tax breaks and other incentives. Nelson says the plan would help attract engineers and scientists to these enterprise zones and create jobs in an industry facing uncertainty.

The U.S. space program is undergoing the biggest transition in a generation with the last space shuttle flight scheduled for next year. Thousands of workers are expected to lose their jobs when the shuttle program ends.
