The Boeing CST-100 Starliner is integrated on top of the United Launch Alliance’s Atlas V rocket at Cape Canaveral Space Force Station. Various tests have been completed to ensure all systems between the rocket and spacecraft are communicating and functioning properly before rollout to the pad.
Teams conducted numerous checks, including a power up of the spacecraft’s avionics system, health checks of the batteries, propulsion system, ordinance system and data flight instrumentation (DFI). Tracking and Data Relay Satellite (TDRS) testing also took place to confirm telemetry and command capability between the launch vehicle and spacecraft and Starliner Mission Control in Houston. The final activities to prepare for the Starliner for its mission are also complete including final cargo load, interior/exterior inspections, and side hatch leak testing.
The integrated Starliner and the Atlas V is set to rollout to the pad at Space Launch Complex-41 at 10 a.m. on Wednesday, July 28, 2021 for the Orbital Flight Test-2 (OFT-2) set to launch 2:53 p.m. ET on Friday, July 30, 2021.
