STS-110
S0 Truss and the Beginning of the Station's Main Backbone
STS-110 installed the S0 truss above Destiny and prepared the Mobile Transporter, establishing the central structural backbone for the ISS's long truss system.

Objective
What this ISS mission set out to accomplish
Install the central S0 truss, connect it to the U.S. laboratory, and prepare the railway and utility infrastructure needed for the station's expanding port and starboard truss segments.
This record treats STS-110 as an assembly or station-support mission rather than as a satellite engineering page, keeping the mission objective separate from the hardware-level ISS engineering record.
Flight and rendezvous
How the mission reached and worked at the station
STS-110 launched on April 8, 2002 using Space Shuttle Atlantis from Kennedy Space Center, Launch Pad 39B.
The 43-foot truss was transferred from Atlantis and attached above Destiny. Four spacewalks connected power, data, cooling, and structural hardware and prepared the Mobile Transporter system.
Hardware and assembly
What was delivered, installed, or reconfigured
Primary hardware or assembly focus: S0 Truss and Mobile Transporter systems.
Installation record: S0 installed above Destiny during STS-110. This is the engineering connection between the mission story and the interactive International Space Station breakdown.
Outcome
What changed on the International Space Station
S0 became the central anchor for the Integrated Truss Structure, enabling later installation of port and starboard truss segments, radiators, solar arrays, and mobile robotics.
The documented result makes STS-110 part of the larger ISS assembly chain, where individual missions progressively added structure, power, laboratories, robotics, thermal control, logistics, and crew-support systems.
