The spacecraft's structure is built around a rectangular
equipment deck that supports engineering components
and the science instruments. The medium-gain antenna
is on the underside, and the low-gain antennas are mounted
on the solar wings. All the equipment is mounted directly
onto the equipment deck except for the canister, the
concentrator and the collector arrays, which are mounted
inside the sample return capsule, which in turn is mounted
on the equipment deck.
The structures subsystem weighs
98.6 kilograms (217.4 pounds).
