Write a first-person, present-tense science fiction story about a diverse group of astronauts who are sent on a one-way mission to colonize a promising new planet. The story should begin with the excitement and anticipation of space travel and systematically reveal the alarming signs that something has gone terribly wrong. In addition, the story should include detailed descriptions of the planet's landscape, the technology the astronauts use to survive, and the physical and psychological toll their circumstances take on each character. End the story with a surprise twist that explains the source of the danger they encountered.
