this constellation of rapid—response satellites is planned to be in orbit by 2025. and before that, firefly is developing a rapid—response rocket for the us space force that can be on standby and ready to take a payload and get it into orbit with just one or two days�* notice. it takes four firefly—designed reaver engines to get that rocket off the ground. and it's the test of one of those that we are here to film today. is this your baby? or is this one of your babies? this is one of my babies. 0k. sporting her lucky launch shoes, brigitte 0akes will be studying the rocket test in great detail. from an engine perspective, we want to make sure that our engines start up healthy, steady state that is healthy, and we're getting the thrust and power levels that we need.
