NASA engineers still struggling to understand why Orion’s heat shield ablated so much
NASA engineers still do not understand why the heat shield on its Orion capsule ablated as it did during its return to Earth on the first unmanned Artemis-1 mission.
The agency is still running tests. It also expressed confidence that the issue will not delay the Artemis-2 mission, the first intended to carry humans on SLS and in Orion and still scheduled for late 2024.
At the same time, agency officials hinted that the third Artemis mission, which has always been planned as putting humans on the Moon for the first time since Apollo, might not achieve that goal. It is still not clear whether the mission’s lunar spacesuits as well as SpaceX’s Starship lunar lander will be ready on time. The latter is facing serious regulatory problems imposed by the Biden administration that is generally preventing it from flight testing the spacecraft.
That second Artemis mission, the first planned to carry humans, is one that actually at present carries the most risk. It will not only use a heat shield that at present engineers do not entirely understand, it will be the first Orion capsule to have the environmental systems necessary for its human cargo. NASA is putting humans on the first test flight of those systems.
