Aug 29 (Reuters) - NASA will proceed with the undocking

of the uncrewed Boeing Starliner capsule not before Sept.

6, the space agency said on Thursday after concluding a review.

Last week, the space agency said its two astronauts who

flew to the International Space Station (ISS) in the Starliner

in June will return to SpaceX vehicle early next year.

Starliner's propulsion system issues were deemed too risky

for crewed return after the capsule experienced a series of

glitches within the first 24 hours of its flight to the ISS.

The journey back to Earth for the Starliner is expected to

take approximately six hours from undocking to landing at White

Sands Space Harbor in New Mexico, NASA said in a blog post.

Ground teams will remotely guide the spacecraft through

necessary manoeuvres for a safe undocking, re-entry and

parachute-assisted landing in southwestern United States.

Starliner has previously completed a successful uncrewed

entry and landing during two orbital flight tests, the agency

said.
