"SpaceX has signed a partnership deal with Bigelow Aerospace (BA) to
offer a taxi service to and from the inflatable habitats BA intends to
put
into orbit.

A SpaceX representative told El Reg that it expect to be ready for
manned
flight by 2015, and commercial services would start shortly
afterwards.

Bigelow is partnering with SpaceX to work with its BA 330 module, an
inflatable habitat based on NASA technology that can hold around six
astronauts in relative comfort. The Nevadan company, set up by Robert
Bigelow, founder of the Budget Suite hotel chain, has had two test
facilities
in orbit for years and now appears ready to move into commercial
operation.
