Once a lunar month, Collins and her late father would don environmental suits and hike across the Sea of Clouds to watch Sol rise over the moon. After her junior year at the Academy, Collins and Karen Farris took a vacation on Risa.
In 2373, Collins joined her fellow Red Squad cadets serving on the USS Valiant on a training mission throughout the United Federation of Planets. The Valiant was near Cardassian space when the Dominion War began and Collins was given a commission as Acting Chief Petty Officer by Tim Watters.
In 2374, when Jake Sisko and Nog were rescued by the Valiant, Collins became upset when she and Jake discussed Luna. During the Valiant's attack on the Jem'Hadar battleship, Collins took the place of a Cadet who had been killed. She later took Riley Shepard's place at the conn after he was killed, but she was unable to restore helm control. With the Valiant almost destroyed, Collins, Nog and Jake left the ship in an escape pod.
Collins and the others were rescued by the USS Defiant, where she was treated by Julian Bashir. Collins defended Watters' actions, although Nog told he may have been a hero and a great man but he was a bad captain. (DS9 episode: "Valiant")
Following the destruction of the Valiant, Collins returned to Tycho, where she received counseling from Deanna Troi and a visit from Nilz Baris. In 2375, she was assigned to the USS Wyandotte as part of a cadet assignment. Collins kept a diary of her life in which she documented her experiences during her recovery.
