EVA suit orientation is mandatory for all passengers who will be participating in any surface excursion involving an EVA suit. This includes all Moon Base 7 shore excursions (GST only), all Mars surface excursions, the Ceres surface walk and The Leap, and the Titan ice flats excursion. Passengers travelling exclusively on legs with no EVA surface access — such as IPS passengers who skip all Mars surface excursions — may still attend orientation but are not required to.

The EVA suit orientation session is conducted by the vessel's EVA systems officer during the Moon Base 7 layover for GST passengers, or at the departure gate for IPS and ORT passengers whose first EVA stop is Mars or Ceres respectively. The session takes approximately 90 minutes and covers the following: suit-up procedure and self-check, buddy-check protocol (each passenger verifies a partner's suit seals and connections), helmet seal and communications system operation, suit environmental controls and the meaning of the suit's alert tones, emergency procedures for suit breach or pressure loss, and the buddy-hold protocol for assisting another passenger in difficulty on the surface.

Completion of the EVA suit orientation is logged in the passenger's voyage record. Passengers who have not completed orientation are not permitted to participate in any EVA surface excursion on that voyage, regardless of prior experience, prior training certificates, or any other qualification. The orientation is vessel-specific and cannot be substituted with training completed on another vessel or at a third-party facility.

The EVA suits used by Pelorus Voyages are the ClearSuit Pro, a third-generation articulated pressure suit designed specifically for expedition passenger use. The ClearSuit Pro accommodates a range of body sizes via an adjustable inner layer; fitting takes place during the orientation session. The suit is considerably more flexible than the suits used in early space programmes and allows a full range of motion for walking, bending, and the arm movements required for activities like golf and surface sports. The suit's onboard life support provides six hours of atmosphere; all Pelorus Voyages surface excursions are planned within this window.

Passengers who missed the orientation session due to a scheduling conflict or who joined the voyage after the session was completed should contact the expedition coordinator immediately. A supplementary orientation can usually be arranged during the first transit leg to the first EVA-capable stop, but this is not guaranteed and depends on the EVA systems officer's schedule.
