T+plus 60 seconds. Now one minute into the Mars 2020 mission, bound for Jezero Crater and a landing next February to explore an ancient river delta where life may once have existed.

Atlas V has broken through the sound barrier to go transonic and passed the period of maximum aerodynamic stresses in the lower atmosphere.

SRB Separation

T+plus 1 minute, 50 seconds. Solid rocket booster jettison is confirmed. All four of the Aerojet Rocketdyne-made solid rocket motors have successfully separated from the Atlas V first stage, having completed their job of providing nearly two-thirds of the energy at liftoff.

The Atlas 5's four strap-on solid rocket boosters have jettisoned as the launcher arcs toward the east from Cape Canaveral. https://spaceflightnow.com/2020/07/28/atlas-5-av-088-mission-status-center/...

Fairing Separation

T+plus 3 minutes, 30 seconds. Payload fairing jettison is confirmed from the edge of space. The two-halves of the RUAG Space-made composite shroud have separated to expose the satellite after ascent through the atmosphere. Also, the Centaur Forward Load Reactor, a two-piece deck that rings the upper stage to support the fairing during launch, has separated as planned.

The main engine is revving back up.

Staging

T+plus 4 minutes, 45 seconds. Successful staging and ignition of the Centaur upper stage is confirmed. The vehicle now weighs a little more than five percent of its liftoff mass. 

The first stage of flight was completed with booster engine cutoff, or BECO, followed by separation of the Atlas V's common core booster. 

That enabled the Centaur's RL10C-1 engine to begin the first of two planned firings today to propel the Perseverance spacecraft on an interplanetary voyage to Mars.

On to the Centaur for the first burn. Check out the RL-10 gimbal for a bit of steering.

MECO-1

T+plus 11 minutes, 35 seconds. The first main engine cutoff, or MECO-1, is confirmed for the Centaur upper stage. The vehicle has reached a parking orbit where it will coast above the Central Atlantic for the next half-hour before the Earth escape burn begins.

ULA says the Centaur upper stage's RL10 engine has completed the first of two firings needed to send the Mars 2020 mission toward the Red Planet.

The rocket will coast in orbit across the Atlantic & over Africa before reigniting at 8:35am EDT (1235 GMT). https://spaceflightnow.com/2020/07/28/atlas-5-av-088-mission-status-center/...

T+plus 17 minutes. Data shows that the first burn by Centaur inserted the rocket into the precise target orbit as planned.

Here's a view of the Atlas 5 rocket as it surpassed the speed of sound moments after lifting off from Cape Canaveral with NASA's Mars 2020 Perseverance rover.

T+plus 35 minutes. A check of Centaur telemetry shows nominal tank pressures, bus and battery voltages, good body rates in the roll.

Main Engine Start-2

T+plus 45 minutes, 5 seconds. Ignition! The Centaur's single RL10C-1 engine has re-ignited to propel Perseverance out of Earth orbit and on the interplanetary trajectory to Mars.
