New Commercial Spaceflight Standard Supports Safety of Suborbital Vehicles

Translations

A new standard developed by ASTM International’s commercial spaceflight committee (F47) establishes a failure tolerance for suborbital vehicles specific to situations of occupant safety.

Failure tolerance, also known as fault tolerance, is the ability of a system to continue satisfying safety or operational objectives in the event one or more components fail.

“Failure tolerance provides a protective measure against inevitable uncertainties in spaceflight,” says ASTM International member Andrew Lake. “The new standard helps provide the framework for consistent occupant safety approaches across original equipment manufacturers and suppliers.”

According to Lake, director of system safety and reliability engineering for Blue Origin, the standard also helps system designers and manufacturers evaluate the effectiveness of design solutions to meet occupant safety objectives.

“The new standard provides an objectives-driven approach to safety, rather than a prescriptive approach,” says Lake, “providing more room for innovative solutions without compromising safety.”

Lake notes the standard (F3479) provides a view of failure tolerance that includes expectations for system safety engineering, human error tolerance, and single points of failure.
