STATEMENT OF WORK

1. Objective/Requirements

The contractor shall provide one (1) compact, slope-capable tractor with specialized attachments and integrated maintenance support services to restore outdoor lunar simulant surfaces at the Crew & Rover Advance Testing & Exploration Readiness Site

(CRATERS) facility at NASA Johnson Space Center.

The equipment shall be capable of:

• Operating safely and continuously on slopes up to 30 degrees in all directions

(uphill, downhill, and cross-slope)

• Breaking hardened simulant crust formed by environmental weathering

• Tilling compacted simulant to a controlled depth of one to four inches

• Redistributing small rocks and pebbles to the surface without accumulation

• Moving and redistributing larger volumes of simulant material

• Grading, leveling, and finishing simulant surfaces

• Performing all operations without damaging the ABS geoweb drainage grid installed beneath the simulant surface

• Supporting periodic resurfacing operations required approximately every one to two months to maintain consistent test conditions for Artemis program crew training and rover testing activities.
