Artemis II: Contingency Access Platforms

Crews test temporary contingency access platforms on the mobile launcher simulator tower on Wednesday, Oct. 29, 2025, at the Launch Equipment Test Facility at NASA’s Kennedy Space Center in Florida. The platforms will allow engineers to access the vehicle’s flight termination system on the rocket and the mobile launcher while at the pad rather than rolling back to the Vehicle Assembly Building to retest them. For Artemis II, four astronauts will venture around the Moon in early 2026, the first crewed mission on NASA’s path to establishing a long-term presence for science and exploration through Artemis.
