TECHNICAL DEFINITION

Nominal describes the expected, designed, and optimal operational state or performance parameters of a spacecraft, subsystem, or mission phase, indicating that all systems are functioning within their specified tolerances and without anomalies.

BACKGROUND

The economy of the state of Florida is the fourth-largest in the United States, with a $1.726 trillion gross state product (GSP) as of 2024. If Florida were a sovereign nation (2024), it would rank as the world's 15th-largest economy by nominal GDP according to the International Monetary Fund, ahead of Spain and behind South Korea. Agriculture, tourism, industry, construction, international banking, biomedical and life sciences, healthcare research, simulation training, aerospace and defense, and commercial space travel contribute to the state's economy.
