A Russian resupply ship is racing toward the International Space Station as another U.S. cargo craft nears the end of its mission. Meanwhile, the Expedition 65 crew focused its research activities today on a variety of physics and biology studies.
Russia's ISS Progress 78 resupply ship (78P) is orbiting Earth today following its Tuesday launch from the Baikonur Cosmodrome in Kazakhstan. The 78P will arrive on Thursday with over 3,600 pounds of food, fuel and supplies, for an automated approach and docking to the Poisk module at 9:03 p.m. NASA TV will broadcast its arrival beginning at 8:15 p.m. on the agency's website and the NASA app,.
The next cargo craft to depart the station will leave on July 6 at 11:05 a.m. EDT. The SpaceX Cargo Dragon will undock from the Harmony module 's Earth-facing international docking adapter and parachute to a splashdown off the coast of Florida a few hours later.
NASA Flight Engineers Shane Kimbrough, Megan McArthur and Mark Vande Hei worked throughout Wednesday readying the Cargo Dragon for next week's departure. Commander Akihiko Hoshide and Flight Engineer Thomas Pesquet joined the NASA trio packing and organizing Dragon before final loading of critical research samples begins for analysis back on Earth.
Hoshide also kicked off the InSpace-4 physics study that will explore advanced materials and manufacturing techniques. Pesquet collected and stowed his blood samples before charging a headband device that monitors an astronaut's sleep patterns for the Dreams study.
McArthur and Vande Hei collected samples of microbes from station surfaces and air for incubation and analysis. Some of those samples will be returned to Earth next week inside the Cargo Dragon.
Cosmonauts Oleg Novitskiy and Pyotr Dubrov concentrated on maintenance and science in the orbiting lab's Russian segment. Novitskiy checked Orlan spacesuit gloves and analyzed the air in the Zvezda service module. Dubrov worked serviced a variety of life support hardware.
