NASA's plan for an off-world colony: a floating city above Venus

Story highlights

  • NASA is studying the possibility of sending a manned mission into the relatively benign atmosphere of Venus
  • The concept involves sending an aeroshell that would contain a folded helium airship in the planet's atmosphere
  • At 30 miles above the planet's surface, the gravity, atmosphere and radiation protection is similar to that of Earth
  • The space agency says the mission could involve creating a floating blimp city for a permanent manned presence
