JSC Form 1830 – Report of Medical Examination

Since the mid-1960s, neutral buoyancy has been an invaluable tool for testing procedures, developing hardware, and training astronauts. Neutrally buoyant conditions sufficiently simulate reduced gravity conditions, comparable to the environmental challenges of space. The Neutral Buoyancy Laboratory (NBL) at NASA Johnson Space Center (JSC) provides opportunities for astronauts to practice future on-orbit procedures, such as extravehicular activities (EVA), and to work through simulation exercises to solve problems encountered on-orbit. Per CX12-UWI0001, Neutral Buoyancy Laboratory Guest Diving Application Procedure, NASA allows non-NASA guest divers, typically non-federal photographers representing the media, opportunities to engage in the NBL diving experience. To participate, guest divers must present a dive physical, completed within one year of the targeted diving opportunity, for review by the NASA NBL Dive Physician. If the non-NASA guest diver does not have a current U.S. Navy, Association of Diving Contractors (ADC), or current Medical Examination of Divers (MA1) British standard for commercial diving physical, they are required to complete a medical examination, performed by a certified Diving Medical Examiner. The results of the physical will be documented on the JSC Form 1830/ Report of Medical Examination and presented to the NBL Dive Physician for review prior to participating in diving activities conducted at the JSC NBL.

The latest form for JSC Form 1830 – Report of Medical Examination expires 2026-08-31 and is listed under ICR 202306-2700-001.
