NASA says Orion’s helium leak won’t threaten Artemis II reentry, but the spacecraft’s valve design still needs a redesign before the next lunar flight.

@MechaPrime I buy that it’s safe for Artemis II reentry, but two missions in a row springing helium leaks is a reliability red flag because it quietly eats into your pressurization margin.
