After running through LOX fill, setup, and pressurization checklists, the cold flow commences with a beautiful stream of liquid oxygen flowing from the engine. Flow rates and temperatures are recorded and checked both in real time and later during a data review. Functionality of the entire system is evaluated. If necessary, more flows are conducted, or the system is prepared for a hot fire test in the coming days.
Tune in this weekend and we will update you on where to find XCOR on the road (and online), and an update on how we will answer more of your questions in the coming weeks.
