What commenters say

  • The Crew Dragon's water landing is a reliable and safe method for emergency aborts, but the recovery process can be time-consuming.
  • Propulsive landing could be a viable alternative to water landing, potentially reducing recovery time and increasing efficiency.
  • The use of parachutes provides a level of redundancy and safety in case of an emergency abort, but may not be suitable for all scenarios.
  • The development of the Crew Dragon spacecraft is focused on meeting NASA's requirements for ISS missions, rather than pursuing more ambitious goals like propulsive landing.
  • The Starship program is being developed separately, with the goal of establishing a human settlement on Mars, and may not be certified for NASA use in the near future.
  • The recovery process for a normal landing may be shorter than for an abort test, as it does not involve the same level of safety checks and procedures.
  • The use of military personnel and equipment, such as helicopters and rescue teams, can aid in the recovery process in the event of an emergency abort.
