Welcome to the semi final of The Challenge! In just 48 hours the Starship TC1 will be coming down back to Earth. Your mission has been tough, challenging and extreme. You have lost crew members in deep space but you 5 have almost made it to the end. But only one Sector can return home, will it be the mission-long Power team Alpha? Or the Underdogs of Delta? Good luck and for all of you, your trip is almost over.
