Other Cargo

The freighter’s cargo includes spare parts, research gear and other equipment; propellant for ISS maneuvers; water; and compressed air and oxygen.

Meanwhile, the ISS crew is preparing for the arrival of the Japan Aerospace Exploration Agency’s (JAXA) fourth H-II Transfer Vehicle (HTV-4), or Kounotori, supply craft. The HTV-4, loaded with 3.9 metric tons (4.3 tons) of pressurized and 1.5 metric tons of unpressurized cargo, is scheduled to lift off from the Tanegashima Space Center on Aug. 3 at 3:48 p.m. EDT.

The HTV-4 would rendezvous with the station on Aug. 9. Nyberg, Cassidy and Parmitano will be standing by at the controls of the ISS Canadian robot arm to grapple the JAXA freighter and berth it to the U.S. segment Harmony module. Grapple is scheduled for 7:29 a.m. EDT.

Over the weekend, flight control teams also wrestled with a series of computer processor interruptions aboard the European Space Agency’s Albert Einstein Automated Transfer Vehicle-4 supply ship. The ESA freighter carried out an automated docking with the ISS Russian segment on June 15, initiating a six-month stay. The four processors resumed normal function on July 29, but the reason for the difficulties had not yet been resolved.
