Formerly named Mr. Steven. GO Ms. Tree – often shortened to Ms. Tree – is a fast, highly maneuverable vessel that was chartered by SpaceX from 2017 until 2021 in support of the fairing recovery program. The ship was configured with a large net to catch payload fairings.
As of April 2021, SpaceX is no longer attempting to catch payload fairings and Ms. Tree has been retired from SpaceX operations. The name ‘Ms. Tree’ is a pun of the word ‘Mystery’.
Ms. Tree was originally built as a fast crew/supply vessel, serving the oil industry in the Gulf of Mexico. In late 2017, the vessel was chartered by SpaceX as they continued the development of the fairing recovery program. Ms. Tree was assigned to Pacific Ocean operations and based at the Port of Los Angeles, California.
