ISS Expedition 15 (2nd Crew) – Official NASA Lapel Pin

Celebrate a mission that helped shape the backbone of the International Space Station. Expedition 15 saw four astronauts rotate through the crew, with the second team continuing the work of expanding and strengthening the ISS during a major phase of construction.

During this expedition, the Station’s Integrated Truss Structure grew dramatically — STS‑117 delivered the S3/S4 truss, and STS‑118 added the S5 truss, extending the ISS power and cooling systems and pushing the outpost closer to its final form.

The second crew carried that momentum forward, supporting assembly, operations, and science while keeping the Station running smoothly during a period of rapid growth.

This official lapel pin captures a mission defined by teamwork, engineering milestones, and the steady hands that kept the ISS evolving piece by piece.
