The ss catherine johnson northrop grumman named the crs15 after the nasa mathematician a black woman who, time and again broke through the barriers of gender and race. It is a company tradition to name each cygnus spacecraft after an individual has played a pivotal role in human space flight her hand, written calculations were critical to america’s success during our first human space flight missions. Again this is february 20th. The 59th anniversary of john glenn’s flight and uh when he again became the first american to orbit the earth. It is a perfect tie to the ss katherine johnson while nasa had used the ibm computers to calculate the complex orbital. Trajectory glenn asked to have catherine johnson verify the calculations by hand and would not fly until she gave the go five. Four three two one: we have engine ignition main engine start and we have liftoff of antares for the ng 15 mission from the wallops flight facility. Five four three, two one: we have engine ignition Music main engine starter and we have this off of the interior for ng 15 missions are at one hundred percent attitude. Poor pressures and equal substances are nominal. The ss catherine johnson takes flight on this. The 59th anniversary of john glenn’s mercury flight carrying eight thousand 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 good, core pressures. Music engines remain steady, added to nominal Music, max q attitude, nominal Music first stage, passing through the area of maximum dynamic pressure on the rocket 90 seconds into the light Music.

This first stage burns for a little over three minutes. Three minutes 18 seconds until main engine cut off Music about 90 seconds to stage one burnout attitude nominal engines at 100 and steady t plus two minutes. Music. All subsystems continue in nominal performance. Also, some sub systems are nominal we’ll, be ready to shift down to 80. 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 all subsystems, nominal fairing separation, enter stage separation, confirm fairing separation and enter stage stage 2 ignition 2 Ignition confirmed stage 2 is a solid rocket motor burns for about 2 minutes 44 seconds stage. 2 burnout attitude nominal stage, two burnout, good attitude: uh we’ll we’re in a coast period now 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.
