A Japanese HTV cargo freighter is set for launch Tuesday (U.S. time) aboard a powerful H-2B rocket, ferrying six new lithium-ion batteries, a Sony-developed laser communications terminal, fresh water and other equipment to the International Space Station.

A commercial module mounted outside the International Space Station last year will remain attached to the orbiting research complex for at least three more years, carrying out additional tests for future space habitats and serving as a storage closet for the lab’s crew.

SpaceX has launched a Falcon 9 rocket with a previously-flown first stage booster carrying the SES 12 communications satellite, an all-electric, multi-band video and data relay platform to serve the Asia-Pacific region. Liftoff from Cape Canaveral occurred at 12:45 a.m. EDT (0445 GMT), and SpaceX did not plan to recover the first stage.
