Mission Summary: This will be the fifth (out of 9) suborbital spaceflights. Here is how the mission will unfold. When the countdown reaches T-3 seconds the engine will ignite and go up to full thrust, once the countdown reaches T-0, the vehicle will be released, and it will begin the ascent sequence. As the vehicle gains speed and altitude, it will slowly begin to pitch over to obtain the proper trajectory. Once the vehicle reaches 10 kilometers (10,000 meters) there will be a go no-go poll. If it is believed the vehicle is still capable of reaching the proper trajectory, the launch escape tower win he jettisoned and the ascent will continue as planned. If it is believed that the vehicle is not capable of reaching the proper trajectory, the abort sequence will be activated and the capsule with splash down safely. After the go no-go poll, the ascent sequence will continue until the engine runs out of propellant. After engine cutoff, the stage will jettisoned, and the capsule will continue on the trajectory. Once the capsule reaches the highest point in the trajectory it will re-orient and activate the retro pack, a small cluster of boosters designed to slow the vehicle's trajectory to facilitate a safe entry into the atmosphere. After the engines have burned out the vehicle will then enter the atmosphere, afterwards the parachutes will lead the capsule to a safe return.
Mercury-Redstone lifts off from the pad.
Ascent continues nominally.
Vehicle reaches MECO (Main Engine Cut Off).
Booster separates, the coasting phase of the flight begins.
Vehicle begins to slow down velocity for entry.
Mercury enters the atmosphere.
Capsule splashes down and is recovered shortly after.
