All systems are go. Team minus 15 seconds and counting. 9, 8, 7, 6, 5, 4, 3, 2, 1. We have lift off of Teedras M on Atlas V rocket from Space Launch Complex 41. Teedras M is securing space to ground communication for NASA's low-Earth orbit operations, including the International Space Station. The Atlas V rocket should be all in a very standard to its planned path in inclination of 26.2 degrees. During the voice of Patrick Moore providing launch vehicle ASM data, Patrick is the United Launch Alliance Denver Network Operation Center on Control Center. On speed and objective rush is all looking good. Now, at 5.45, we're in flight. The Atlas rocket carrying Teedras M reach Super Sonic Speed at 1 minute, 20 seconds into flight. Now passing 1 minute into flight. The vehicle is now 3 miles in altitude, and traveling at 1100 miles per hour. Standing 5 for Max Q. Now passing 1 minute, 10 seconds into flight. 32 seconds into flight. Mach 1, Atlas V is now Super Sonic. 1 minute, 30 seconds into flight. Now passing through Max Q, maximum dynamic pressure. This is the point when mechanical stress on the rocket reaches its peak because of the rocket's velocity and resistance created by the Atlas. The AR-81-80 is throttled down to 95% thrust as expected. Engine response looks good. This engine thrust profile will continue until the vehicle reaches a program 5G acceleration limit. About 2 minutes into the flight of Atlas. And passing 2 minutes into flight, approximately 2 minutes remaining in the first stage of flight. Vehicle trajectory, traveling right down the middle of the range track, looking good. AR-81-80 engine operating parameters also looking good. Booster engine cut off, slated for 4 minutes, 2 seconds after launch. Yeah, this 5 rocket now is just 1 half of what it did at launch, burning propellant at a rate of almost 2,600 pounds per second. And vehicle is gone to close loop guidance. Now passing 2 minutes, 30 seconds into flight. And RCS Parababab has been fired, sent our reaction control system now pressurizing the flight levels. Atlas 5 is now 30 miles in altitude, 43 miles down range distance, traveling at 4,700 miles per hour. And now passing 3 minutes into flight, approximately 1 minute remaining until booster engine cut off. AR-81-80 continues to perform well. Vehicle trajectory continuing down the middle of the range track. ULA's Patrick War providing vehicle-assent data. 3 minutes 20 seconds into flight. Now passing 3 minutes, 30 seconds into flight. Mach 10. And vehicle has reached the 5G throttle limit. And we've begun boost phase chill down. Less than 30 seconds away from booster engine cut off. 3 minutes 50 seconds into flight, standing by for BCO momentarily. Six seconds after BCO, the Sintar second stage will separate from the Atlas booster. And we have BCO boost range and cut off standing by for stage set. 10 seconds after separation. We have good indication of stage separation. The central signal RLC engine ignites for the first time. We have ignition and full thrust on the RL-10. The RL-10 produces 22,900 pounds of thrust and burns for just under 8 minutes. And we have good indication of faring separation. This is the first of two planned burns for today's mission. This first burn should last approximately 13 minutes and 40 seconds. The payload faring, protecting TDRSM during its flight through the atmosphere. And the RL-10 is operating parameters all looking good. Vehicle trajectory continuing down the middle of the range track. The Sintar is now 107 miles in altitude, 350 miles down range distance, traveling at 11,160 miles per hour.
