The ground support team is responsible for maintaining the trailer and acquiring data from the rocket. They also build our test equipment and gather the data from tests. The trailer contains several major elements; the most prominent is the launch rail, standing at about 40ft tall when upright. The plumbing systems for the nitrous oxide and nitrogen are also on the trailer, as well as the flight data acquisition system, both of which are used for test fires.
