The last of Japan’s current series of HTV cargo freighters arrived at the International Space Station Monday with a fresh set of lithium-ion batteries, ready for installation on the research lab’s solar power truss after the scheduled docking of a two-man crew on a SpaceX Dragon spaceship later this week.

NASA astronaut Chris Cassidy, commander of the space station’s Expedition 63 crew, controlled the robot arm for Monday’s capture of Japan’s ninth H-2 Transfer Vehicle.

The mission marks the final flight of Japan’s current HTV spacecraft design, which first reached the space station in 2009.

Unlike the HTV, which is grappled by the robotic arm and berthed with the space station, Japan’s HTV-X is designed to directly dock with the orbiting outpost, using the same docking ports as SpaceX’s Crew Dragon and Boeing’s Starliner crew capsules.

Japan’s ninth and final HTV cargo ship has been captured by the International Space Station’s robotic arm, under the control of astronaut Chris Cassidy.

Japan’s space agency is also delivering new science racks for to the space station NASA and the European Space Agency, plus a water tank and fresh food for the research lab’s crew.

Assuming it launches May 27, the Crew Dragon is scheduled to dock with the space station May 28.

The arrivals of the HTV and Crew Dragon in quick succession will make for a busy few days on the space station, which is operating with a limited crew of three, and just one NASA astronaut responsible for the U.S.

The batteries on the ninth HTV flight will be installed on the space station’s outboard S6 segment on the far starboard side of the craft’s 356-foot-long (108.5-meter) truss structure
