3. ASSEMBLE THE SCIENCE INSTRUMENT BOOMS.
View the whole assembled model
Lunar Prospector's science instruments are supported at the end of three booms. Each boom is made of thin fiberglass trusswork, which is tightly coiled up inside a cannister prior to launch, ready to spring out. The scale size of the cannister is the size of the rectangles, labelled A, G, and M, protruding from the spacecraft bus. Enroute to the Moon, the booms were deployed by reeling out a restraining tape, one for each boom, from the center of the their support structure inside the bus.
- Cut out one of the SCIENCE INSTRUMENT BOOMS from Sheet 1.
- Lightly score along each of the two lines running lengthwise along the piece. Score the two little triangular tabs so they'll fold over easily.
- Fold along each scored line, bringing two outer panels up to touch, creating a boom with a triangular cross-section. Crease the fold. Fold the two triangular tabs over onto the mating panel, and glue to hold the boom's shape. Apply more glue along the crease.
- Repeat with the two remaining SCIENCE INSTRUMENT SUPPORT BOOMS.
