The SSTO L-2 Dunerider Mk.3 is a long range Passenger SSTO with a large cargo volume.

It can bring around 6 crew and 6 t payload to Duna orbit and back to Kerbin. It is also capable of landing horizontally on Duna, but it is very hard and it will need refueling after getting back in orbit, before returning to Kerbin.

It has at least 2600 m/s dV in LKO with 6 t payload.

Ascent Profile

  1. Full throttle, SAS on, Stage.
  2. At 60 m/s lift the nose gently and take-off.
  3. Build up speed to 450 m/s at sea level. (Below 300 m)
  4. Pitch up gently to 10° above horizon, without losing speed.
  5. At 18 km engage the LV-N. (Action Group 1)
  6. At 22 km switch RAPIER Mode (Action Group 2)
  7. Keep going at 10° above horizon.
  8. At 30 km pitch down to 8° above horizon.
  9. Shut down the RAPIERs when they run out of oxidizer. (Action Group 3)
  10. When AP is above 50 km point the nose Prograde.
  11. Throttle down when AP is a few km above your desired altitude.
  12. Circularize at AP.

Descent Profile

  1. 80 km orbit. In Map mode, focus Kerbin and turn camera so KSC is facing towards you right above the Navball.
  2. Time warp until your spaceplane is right behind Kerbin.
  3. Put a maneuver node right where you orbit appears from behind Kerbin on the left side.
  4. Pull the retrograde handle until the maneuver is ~100 m/s dV.
  5. Move the maneuver node until the planned orbit intersects the surface through KSC.
  6. Pull the prograde handle until the maneuver is 70-80 m/s dV.
  7. Perform the maneuver.
  8. Turn Prograde and time warp till you enter atmosphere.
  9. Keep nose 30° above horizon until around 40 km altitude.
  10. Hold 5° pitch until you reach landmass where KSC is located.
  11. You should be passing over the coast at 25-30 km altitude.
  12. Pitch down 5°-10° below horizon and aim to pass the mountains at 10 km, at 650-750 m/s.
  13. Pitch down further, if needed, and aim for a point about half the runway length in front of the runway.
  14. At 200 m, flare and aim for the runway.
  15. Use Airbrakes and Flaps (Brakes) to slow down to 60-70 m/s.
  16. Touch down with 50 m/s and less than 3 m/s vertical speed.
