火箭升空第一视角全过程

we have starboard engine ignition port and center and vehicle has now begun the pitch over maneuver all three rsxt eight engines look good at this time the core booster is now throttling down at the partial thrust level and that core booster has now reached the desired partial thrust bubble engine perimeters continue out good vehicle is now three miles an outstued five miles downrange distance traveling in a velocity of one thousand miles per hour engine parameters continue to look good at this time vehicles now passing through max q maximum dynamic pressure mark one delta four is now supersonic port， starboard and center rsxiate engine parameters are within the expense good operating parameters right now the second stage reaction control system pressurization valve has opened delta four now hundred and thirty seconds into flight flying an announce due to nineteen miles downrange distance of fourteen miles that's four has gone close to guns vehicle body rates are as expected three minutes remaining in the booster phase of flight that's for rocket we've now just one half of what it did at launch burning propellant at a rate of almost five thousand pounds per second one minute until port and starboard booster range and cut off and all three rsx skate engines are showing good performance at this time vehicle body rates are near zero thirty seconds remaining now until the port starboard booster engines cut off and two minutes remain in booster phase of flight two minutes from amy and tobico strap on boosters and now throttling down to the partial thrust level engine response looks good had drop on booster cut off and strap on separation the center core are a sixtia day is now throttling back up to the high power level the upper state's lock system has begun the boostface children sequence to begin thermal conditioning of the oral tan engine one minute remaining in the booster phase of flight and now the upper stage fuel system has begun the boost faced fuel down sequence core engine chamber pressure continues to look good at this time core booster is now throttling down in preparation for beaco and we have beaco booster engine cut off have stage separation successful separation of the first and second stages we're seeing the nozzle deployment begin on the upper stage engine and we have crease ignition on the dcss。
