Mission 21, named Red Planet Landing used to be the final of the original set of missions. Here, you'll fly to and land on the red planet, RED. This mission is very similar to the lunar landing.

You'll need to assemble the N1-LK-LOK vehicle exactly as directed to be able to complete the mission. After docking with the LK lander in HOM's orbit, fly to RED via LUN. Enter the red planet's orbit, land on the surface, take a picture, and fly to HOM to complete the mission.

The N1-LK-LOK must be assembled as follows:

  1. N1 Block A
  2. N1 Block B
  3. N1 Block V
  4. LK Lander Legs
  5. LK Lander Core
  6. N1 Payload Fairing
  7. LOK Service Module
  8. LOK Crew Capsule
  9. LOK Docking Module
  10. LOK Fairing
  11. N1 Escape Tower
