Sept 24 (Reuters) - NASA said on Tuesday the launch of

its Crew-9 mission with SpaceX has been pushed back to Sept. 28

due to Tropical Storm Helene.

SpaceX's upcoming Crew Dragon mission, a routine flight

called Crew-9, is expected to send one NASA astronaut and a

Russian cosmonaut to the International Space Station.

Although Helene is moving through the Gulf of Mexico and

expected to impact the northwest of region of Florida, it is

large enough that high winds and heavy rain are expected in the

Cape Canaveral region, from where the mission is set to be

launched.

The Crew-9 mission was originally stated to be launched no

earlier than Aug. 18, but was pushed back a month to spend more

time analyzing issues with Boeing's ( BA ) Starliner spacecraft,

which remains docked at the station.

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr

Gorbunov are to launch aboard the Dragon spacecraft to the ISS,

on what will be the ninth crew rotation mission with SpaceX

under the space agency's Commercial Crew Program.
