In February, 2163, he accompanied First officer Travis Mayweather and Williams to the surface of the planet Hansen's Planet as part of their survay mission. The trio shared a friendly argument about the Federation's future while they were searching for the local lifeforms. However, the locals found them first and attacked the away team. Due to the newly discovered dangers of the transporter, Captain Reed didn't want to risk a beam up, so he detonated a photonic torpedo in the planet's atmosphere to scare of their attackers.
