Why does Houston take control after space shuttle takes off?

Houston takes control after a space shuttle takes off to monitor and manage the flight's trajectory and systems. The ground control team, known as Mission Control, is responsible for ensuring the safety and success of the mission, providing real-time data analysis, and communicating with the astronauts. This transition allows the crew to focus on their immediate tasks, while experts on the ground handle any anomalies or changes in the mission profile. Additionally, the ground team has access to extensive resources and expertise that support the shuttle's operations during its ascent and beyond.
