The investigation into Boeing's troubled 787 Dreamliner aircraft is now linked to a company which also supplies batteries to the International Space Station.

Bloomberg reports that Japan-based battery maker GS Yuasa Corp. "won a contract in August to supply lithium-ion battery cells to help power the International Space Station."

The lithium-ion batteries are at the center of the investigations into the Dreamliner. On January 7, a fire started in the auxiliary power unit of a Japan Airlines 787 at Boston's Logan International Airport, according to the Associated Press. Then on January 15, a battery failure aboard a 787 Dreamliner in the All Nippon fleet forced an emergency landing.

The fires prompted airline safety agencies in the U.S., Japan, Europe, India and Ethiopia to ground the Dreamliner until investigators could figure out what was happening.

Although G.S. Yuasa supplies batteries for both the Dreamliner and the ISS, a NASA spokesperson tells Bloomberg the power cells are different, and they're monitoring the FAA's investigation.

No word on how long the investigation with continue, but the Daily Mail reports G.S. Yuasa is "fully cooperating" with authorities.

Boeing rolled out its first Dreamliners in 2011, saying they make passengers more comfortable because of cleaner air, bigger windows and more overhead storage space. Boeing also says it has 20% better fuel efficiency than other airplanes it its class.
