Paragraph- Sent 1: Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit .
Sent 2: Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years .
Sent 3: Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes .
Sent 4: The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold .
