Re-entry steering

I dare you to take the land in the valley challenge with this Immediate re-entry Sandbox
Planet in image included

Note: This is optimized for Cylero/Mars in the newest solar system, not the classic one, as the two Cyleros
have different gravity and atmospheric characteristics.

USER MANUAL

Recommended Settings

• Enable re-entry damage, re-entry trail, and camera shake for the best experience!

Preparing the entry

• Get into a hyperbolic orbit with periapsis at 11.5 km. (i.e. just an encounter).
• There is no fuel to get into an elliptic orbit.
• Ditch the cruising stage.
• Face retrograde.
• Activate RCS 10.

During entry

• Your entry velocity will be around 3630 m/s. (On real Mars that would be 12000 m/s)
• Aerodynamics become effective around 22-18km msl.
• Let RCS (activation 10) thrusters steer you through the atmosphere to where you want to land.

Steering guidelines

• Gain more lift to go up slightly if you need a longer distance. Simply tilt forward 10 to 20 degrees, but be careful, before you know it you'll skip the atmosphere.
• To steer left or right simply yaw left or right. This can be done more aggressively.
• Always monitor your fairing base, which becomes the hottest part next to your heat shield. If it gets too hot (700 C), re-center.
• It is not recommended to exceed 20 degrees for longer periods of time in any direction.
• Lift and steering can of course be combined.
• At slower velocities, you can exceed 20 degrees more safely.

Landing

• When approaching around 1200 m/s, re-center, ditch the fairing.
• Open the chute.
• Proceed to ditch the heat shield.
• Ignite the landing stage.
• It is mandatory to activate RCS 7 in order to control it.
• Ditch the chute at a comfortable velocity (around 200 m/s) and land.

pro-tip: quicksave before re-entry, experiment and have fun!
