Catherine johnson takes flight on this. The 59th anniversary of john glenn’s mercury flight carrying 8 000 pounds of cargo to the international space station good performance on the first stage so far stage. One continues: nominal performance inches at 100 percent. Good core pressures, Music engines remain steady attitude, max q attitude nominal first stage, passing through the area of maximum dynamic pressure on the rocket 90 seconds into the this flight stage burns for a little over three minutes. Three minutes 18 seconds until main engine cut off about 90 seconds to stage one burnout attitude nominal engine’s at 100 and steady t plus two minutes. All subsystems continue in nominal performance. Also, some subsystems are nominal we’ll, be ready to shift down to 80 percent on the engines at 170. start up slow, throttle down throttling down at three minutes into the flight main engine cutoff coming soon throttle down to 55 percent main engine cutoff. We have miko and terry’s entering into a co stage. Fairing separation will occur about 30 seconds later, as we lose side of the vehicle now. Switching to animation, some controlled firings uh on the inter stage of the rocket attitude nominal good separation, 20 seconds to stage two ignition all subsystems, nominal fairing separation, enter stage. Separation confirm fairing separation and interstage stage. Two ignition stage: 2 ignition confirmed stage 2 is a solid rocket motor burns for about 2 minutes 44 seconds stage. Two will continue to burn for another approximately two minutes: altitude: 138 kilometers mission time 300 seconds, velocity 4.
8 kilometers per second altitude, 150 kilometers. All systems continue to perform nominally good calls five minutes 15 seconds into today’s flight h2 motor pressure, nominal attitude. Nominal altitude is 170 kilometers, roughly one minute to stage two burnout. All stage 2 and gnc parameters continue to be nominal 6 minutes 15 seconds into the flight coming up on stage 2 burnout of that solid rocket motor that will initiate a two minute coast period until second stage separation stage, two starting to tail off roughly 15 seconds To burn out stage 2 burnout attitude, nominal stage, 2 burnout, good attitude, we’ll air we’re in a coast period now cygnus exposed after that uh fairing separation and will continue to carry the second stage with it. Until about nine minutes into the flight attitude attitude. Nominal expected attitude control system, thruster firings received continuing on course, roughly one minute to payload separation, altitude, 185 kilometers velocity 7.5 kilometers per second. All systems continue to operate as expected, approximately 30 seconds to spacecraft separation attitude. Nominal systems continue to perform as expected attitude corrections, maintaining expectations lcgso. I just released red team to the pad copy that spacecraft separation confirmed nine minutes into today’s. Flight cygnus has separated from the second stage lc ace. That concludes our callouts copy, that ace okay, uh ng.
