  • At the scheduled time—7:05 a.m. EDT, July 14—the SpaceX Dragon autonomously undocks from the ISS.
  • The docking mechanism at the space-facing (zenith) port of the Harmony module disengages.
  • Spring-loaded pushers gently separate the capsule from the ISS.
  • Once free, thrusters fire in a choreographed sequence to move the spacecraft safely away from the station.

This phase typically takes a few minutes, but full separation and positioning may take up to an hour.

3. Phasing Burns and Orbit Adjustment

After undocking, the Dragon performs a series of departure burns:

  • These engine firings adjust the spacecraft’s altitude and speed, moving it into a lower orbit.
  • The Dragon remains in orbit for several hours, allowing ground controllers to:
    • Finalize re-entry timing
    • Verify weather and sea conditions at the splashdown site
    • Run diagnostics on onboard systems

The duration in orbit before re-entry varies depending on mission objectives and ground recovery readiness.

4. Deorbit Burn

Once all conditions are “go” for return:

  • The spacecraft performs a deorbit burn—a critical engine firing that slows it down enough to begin descent into Earth’s atmosphere.
  • This burn typically lasts 6–12 minutes, reducing orbital velocity by about 100–150 m/s.
  • Following this, the unpressurized trunk section (containing solar panels and radiators) is jettisoned.

Only the crew capsule continues toward Earth.

5. Atmospheric Re-entry

The capsule begins re-entry at hypersonic speeds, reaching up to 28,000 km/h (17,500 mph).

  • The heat shield protects the vehicle from temperatures exceeding 1,600°C (2,900°F) caused by atmospheric friction.
  • Plasma buildup around the capsule may cause a brief blackout of communication for a few minutes.

Re-entry trajectory and timing are pre-calculated to ensure the capsule lands precisely in the designated recovery zone.
