New HTV Launch Date Adjusts Spacewalk Dates as Science Continues

JAXA (Japan Aerospace Exploration Agency) has rescheduled the launch of its HTV-7 resupply ship to the International Space Station to Thursday, U.S. time. As a result of the new launch and arrival dates for the HTV-7, the target dates for a pair of maintenance spacewalks have been adjusted as well.

More than five tons of food, fuel, crew supplies and new science gear is due to launch Thursday at 5:21 p.m. EDT from the Tanegashima Space Center in southern Japan. The HTV-7 with the space cargo will take a 3-1/2 day ride to the orbital laboratory where it will be captured Monday with the Canadarm2 robotic arm around 6:50 a.m. It will then be installed on the station’s Harmony module around three hours later. NASA TV will broadcast all the activities live.

The HTV-7 is also delivering six new lithium-ion batteries to the station which will be the focus of the upcoming spacewalk activity. Robotics controllers will remove the new batteries from the HTV-7 and install them on the Port 4 truss structure. Then astronauts Alexander Gerst and Drew Feustel will begin the final battery hookup work on the first of two spacewalks on Sept. 23. Gerst will go outside a second time with spacewalker Ricky Arnold on Sept. 29 to complete the battery hookups.

Gerst, Feustel and Arnold spent a couple of hours today reviewing their upcoming spacewalk procedures and discussing their concerns with specialists on the ground. Flight Engineer Serena Auñón-Chancellor cleaned the trio’s spacesuits’ cooling loops and refilled the suits’ water tanks.

The entire Expedition 56 crew did manage to conduct a variety of science experiments exploring biology and physics in microgravity. The astronauts researched how mice adapt to space and swabbed their own bodies to collect microbe samples for analysis.  The crew also studied liquid atomization and the composition of meteorites entering Earth’s atmosphere.

The Japan Aerospace Exploration Agency (JAXA) has rescheduled the launch of a cargo spacecraft from the Tanegashima Space Center in southern Japan to 5:21 p.m. EDT Thursday, Sept. 13 (6:21 a.m. Sept. 14 Japan standard time). Live coverage of the launch will begin at 4:45 p.m. on NASA Television and the agency’s website.

The unpiloted H-II Transfer Vehicle-7 (HTV-7) is loaded with more than five tons of supplies, water, spare parts and experiments for the crew aboard the International Space Station.

NASA also will provide live coverage of the arrival of HTV-7 at the space station Monday, Sept. 17 beginning at 5:15 a.m. ET. Capture is scheduled for around 6:50 a.m. After a break, NASA TV coverage will resume at 9:30 a.m. for spacecraft installation to the space station’s Harmony module.

Science and Suit Work as Storms Capture Attention

Science and Suit Work as Storms Capture Attention

The six Expedition 56 crew members started the workweek today with life science and spacesuit maintenance. Meanwhile, a typhoon and a hurricane captured the attention of mission managers and the crew alike.

Commander Drew Feustel and Flight Engineer Ricky Arnold examinedmice onboard the International Space Station and them today for the Rodent Research-7 (RR-7) experiment. The duo checked the breathing and mass of the rodents before placing them back in their habitat and restocking their food. RR-7 is observing how microgravity impacts gut microbes and how it may affect astronaut health.

German astronaut Alexander Gerst of ESA (European Space Agency) wrapped up an experiment before finalizing spacesuit work in the U.S. Quest airlock. He stowed science gear in the morning that analyzed the exhaled air of astronauts to detect signs of airway inflammation. In the afternoon, Gerst completed the battery charging of the U.S. spacesuits then began regenerating metal oxide canisters in advance of a pair of spacewalks at the end of the month.

JAXA (Japan Aerospace Exploration Agency) officials are tracking Typhoon Mangkhut in the Pacific while the station crew sent down imagery of Hurricane Florence in the Atlantic. Mangkhut was moving on a course near a tracking site in Guam which JAXA uses to follow the progress of the Japanese HTV cargo craft after its launch. That launch was postponed from today to a later date. On the other side of the world, the station flew over Hurricane Florence as it neared the U.S. east coast enabling the crew to capture imagery to share with the world.
