NASA once again gambling on the lives of its astronauts for political reasons
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”
NASA this week began the stacking one of the two strap-on solid-fueled boosters that will help power SLS on the Artemis-3 mission, still officially scheduled for September 2025 and aiming to send four astronauts around the Moon.
A NASA spokesperson told Ars it should take around four months to fully stack the SLS rocket for Artemis II. First, teams will stack the two solid-fueled boosters piece by piece, then place the core stage in between the boosters. Then, technicians will install a cone-shaped adapter on top of the core stage and finally hoist the interim cryogenic propulsion stage, or upper stage, to complete the assembly.
At that point the rocket will be ready for the integration of the manned Orion capsule on top.
The article at the link sees this stacking as a good sign that NASA’s has solved the Orion capsule’s heat shield issue that occurred during the unmanned return from the Moon on the second Artemis mission. The image to the right shows that heat shield afterward, with large chunks missing. Though it landed safely, the damage was much much worse than expected. At the moment NASA officials have said it has found the root cause, but those officials also refuse to say what that root cause is, nor how the agency or Orion’s contractor Lockheed Martin has fixed it.
