STATEMENT OF WORK

COASTER Winch

1. Objective/Requirements

The contractor shall provide two (2) complete Atlas APA-2 Winch Mod systems (Kit PN

19785) to support continued operations of the Counterweight Offload Astronaut Suited

Test and Evaluation Rig (COASTER) at NASA Johnson Space Center.

COASTER is a NASA-managed commercial acquisition that enables terrestrial simulation of partial gravity environments, most notably lunar gravity, through mechanical offloading of human and hardware payloads. The winch systems are safety-critical load-bearing components that enable counterweight offloading for suited and unsuited astronaut testing, crew mobility performance studies, spacesuit integration assessments, and Artemis program crew operations development under reduced gravity conditions.

The equipment shall be capable of:

• Personnel-rated hauling capacity of 850 pounds via approved mechanical advantage configuration snatch block configuration to support suited astronaut offloading operations

• Redundant primary and backup braking systems for fail-safe load control during human-rated testing

• Emergency mechanical descent capability without battery power to ensure crew safety in all failure modes

• Compact physical envelope compatible with COASTER's existing structural frame and mounting interfaces

• Interchangeable battery systems to minimize operational downtime during extended test sessions

• Remote control capability (wireless or wired) for flexible test operations

• Overload protection via torque-limiting clutch to prevent equipment damage and ensure crew safety

• Full compliance with applicable portions of ANSI Z359.4-2013, ANSI Z117.1-

2022, OSHA 1926.502, OSHA 1910.140, and OSHA 1910.66 personnel fall protection and confined space entry standards
