The Esmerelda was built not too long before the Auriga. It has made many shipping runs, but mostly is a portable laboratory for the study of the Xenomorphs. In 2284 it was sent to the homeworld of the Aliens for a shipment run to bring a few Xenomorphs back to Earth for study. The Aliens broke out and quickly wiped out all of the crew that did not escape down to 5 survivors, all of which were killed save one, Dr. Cotlow, Chief Science Officer. After that, a strike team of 6 men was sent in to eliminate the rest of the Aliens, which was only 2 left, a single Drone and a Queen. The Queen manages to kill all of them except Pvt James Higgins, who escapes. It is unknown what happened to the ship, but it was most likely quarantined.
