• At 60,000 m ASL, reach and maintain a pitch angle of 5°.
• Press [X] to cut all engines when apoapsis reaches 200,000 m.
• Create a manoeuvre node at apoapsis and circularise into a 200,000 m x 200,000 m orbit.
• Press [AG4] to shut down core stage KS-25 engines and stage for core stage separation.
• Select Action Set 1 and press [AG0] to toggle deploy orbiter solar panels and antennae.

SIDE BOOSTERS - RETURN TO LAUNCH SITE RECOVERY

• Select OV-201 Pathfinder left/right booster from the FMRS menu.
• Press [AG2] to activate three KS-25 engines.

• Orient the booster due west. Press [Z] to throttle up to full power.
• Press [X] to cut engines when Trajectories indicates the landing location shown on the right.
• Press [AG3] to shut down the centre KS-25 engine. Let the booster coast up to apoapsis.
• At apoapsis, select navball Surface mode.
• Orient the booster retrograde by selecting SAS Retrograde mode.
• Click on the brakes icon at the top of the screen to toggle deploy the A.I.R.B.R.A.K.E.S.
• At 2,500 m ASL, press [Z] to throttle up to full power.
• Press [G] to toggle deploy the LT-2 Landing Struts.
• Adjust throttle as required to perform a hoverslam landing.

CORE STAGE - ORBITAL REENTRY AND RECOVERY

• Select OV-201 Pathfinder core stage from the FMRS menu.
• Press [T] to toggle SAS on.
• From a 200,000 m x 200,000 m orbit, create a 200.0 m/s retrograde manoeuvre node.
• Select SAS Manoeuvre mode.
• Position it such that Trajectories indicates the landing location shown on the right.
• Press [AG5] to activate five KS-25 engines. Timewarp to and carry out the manoeuvre.
• Press [AG6] to shut down two of the activated KS-25 engines.
• At 80,000 m ASL, select SAS radial out mode and orient the core stage belly-first.
• At 70,000 m ASL, press [R] to toggle RCS on.
• The navball will automatically switch from Orbit to Surface mode during atmospheric reentry.
• At 15,000 m ASL, select SAS Retrograde mode.
• Click on the brakes icon at the top of the screen to toggle deploy the A.I.R.B.R.A.K.E.S.
• At 5,000 m ASL, press [Z] to throttle up to full power.
• Press [G] to deploy the LT-2 Landing Struts.
• Adjust throttle as required to perform a hoverslam landing.

ORBITER - ORBITAL REENTRY AND LANDING

• From a 200,000 m x 200,000 m orbit, create a 200.0 m/s retrograde manoeuvre node.
• Select SAS Manoeuvre mode.
• Position it such that Trajectories indicates the landing location shown on the right.
• Timewarp to and carry out the manoeuvre. Press [AG3] to toggle the LV-N engines off.
• At 80,000 m ASL, press [AG0] to toggle retract the solar panels and antennae.
• At 75,000 m ASL, orient the orbiter nose-first, wings level, and with a pitch angle of 20°.
• At 70,000 m ASL, press [AG7] to toggle the atmospheric control surfaces on.
• The navball will automatically switch from Orbit to Surface mode during atmospheric reentry.
• At 10,000 m ASL, press [AG1] to toggle the J-90 jet engines on.
• Fly to KSC runway 09 or 27 as required. Press [G] to toggle deploy undercarriage.
• After touchdown, press and hold [B] to brake. Use [AG2] to toggle reverse thrust as needed.
• Press [AG1] to toggle the J-90 engines off.
