The International Space Station experienced a temporary power loss Tuesday night while backup systems maintained power to critical systems. Power was restored quickly and there were no impacts to station operations and the six-member crew was always safe.
Astronauts Kjell Lindgren and Kimiya Yui are training for the robotic capture next week of Japan’s fifth “Kounotori” HTV cargo ship (HTV-5). The HTV-5 will launch from Japan’s Tanegashima Space Center Sunday morning and take a four day trip to the station. The duo will be inside the cupola Aug. 20 to capture the HTV-5 with the Canadarm2. Lindgren also checked on U.S. spacewalk tools while Yui cleaned and inventoried gear inside the Japanese Kibo lab module.
Cosmonauts Gennady Padalka and Mikhail Kornienko are cleaning up after Tuesday’s 5-hour, 31-minute spacewalk. The cosmonauts also talked to Russian spacewalk specialists on the ground Wednesday about the previous day’s external activities.
International Space Station Expedition 44 Commander Gennady Padalka and Flight Engineer Mikhail Kornienko of the Russian Federal Space Agency completed a spacewalk lasting 5 hours, 31 minutes at 3:51 p.m. EDT. The spacewalkers rigged new equipment on the Russian segment of the complex and conducted a detailed photographic inspection of the exterior of the outpost.
This was the 188th spacewalk in support of space station assembly and maintenance, totaling 1,177 hours, or the equivalent of 49 days. Padalka’s ten spacewalks total 38 hours, 37 minutes. Kornienko’s two spacewalks total 12 hours, 13 minutes.
While the cosmonauts were working outside the station, NASA astronauts Scott Kelly and Kjell Lindgren, along with Kimiya Yui of the Japan Aerospace Exploration Agency, sampled lettuce from the Veggie plant growth system on the International Space Station at 12:46 p.m. EDT. Lindgren first harvested half the crop and cleaned the “Outredgeous” red romaine lettuce. NASA is maturing Veggie technology aboard the station to provide future pioneers with a sustainable food supplement — a critical part of NASA’s journey to Mars. This is the first time a station-grown crop has officially been on the menu for station crew members. The remaining lettuce will be frozen on the station until it can be returned to Earth for scientific analysis.
International Space Station Expedition 44 Commander Gennady Padalka and Flight Engineer Mikhail Kornienko of the Russian Federal Space Agency began a planned approximately 6-hour spacewalk from the Earth-facing Pirs Docking Compartment at 10:20 a.m. EDT.
Padalka will be designated extravehicular crew member 1 (EV1) and Kornienko will be extravehicular crew member 2 (EV2). Both will wear Russian Orlan spacesuits bearing blue stripes. Their suits are equipped with NASA helmet cameras to provide close-up views of the work they are performing outside the station.
This is the 188th spacewalk in support of space station assembly and maintenance.
The spacewalking duo will install devices called gap spanners on the hull of the station that will facilitate the movement of crew members on future spacewalks. They also will clean residue off of the windows of the Zvezda Service Module, install fasteners on communications antennas, replace an aging antenna used for the rendezvous and docking of visiting vehicles at Russian docking ports, and photograph a variety of locations and hardware on Zvezda and nearby modules. An experiment designed to measure the space environment first deployed in 2013 will be retrieved and brought inside for its return to Earth.
Flight controllers at the Russian Mission Control Center in Korolev, outside of Moscow, are providing primary support for the spacewalk and coordinating with Mission Control at NASA’s Johnson Space Center in Houston.
NASA Television will provide live coverage of a Russian spacewalk conducted from the International Space Station beginning at 9:45 a.m. EDT. The spacewalk is scheduled to begin at 10:14 a.m. and run about six hours.
Expedition 44 Commander Gennady Padalka and Flight Engineer Mikhail Kornienko of the Russian Federal Space Agency will venture outside the orbiting outpost where they will rig new equipment on the Russian segment of the complex and conduct a detailed photographic inspection of its exterior.
The Expedition 44 crew members continued a wide variety of science experiments Friday as a pair of cosmonauts prepared for a spacewalk Monday morning. On the ground, a new Soyuz crew is preparing for their mission to swap a pair of station residents in September.
One-Year crew member Scott Kelly set up free-floating microsatellites for the long-running SPHERES-Slosh experiment which observes how liquids such as rocket fuel behave in space. New station residents Kjell Lindgren and Kimiya Yui explored vision changes in space as they scanned each other’s eyes with an ultrasound and measured their blood pressure for the Ocular Health study.
Spacewalkers Gennady Padalka and Mikhail Kornienko tested their spacesuits Friday. The cosmonauts will spend 6-1/2 hours upgrading hardware, retrieving an external experiment and photographing the exterior condition of the Russian modules.
In Russia, three new Soyuz crew members completed a series of mission simulations ahead of their departure to the Baikonur Cosmodrome launch site in Kazakhstan. Veteran cosmonaut Sergei Volkov will command the Soyuz TMA-18M spacecraft when he launches Sept. 2 with fellow crew members Andreas Mogensen and Aidyn Aimbetov. Volkov will swap places with Padalka who will return to Earth Sept. 12 with Mogensen and Aimbetov.
The International Space Station crew worked a variety of biomedical experiments in the midst of preparations for Monday’s spacewalk. Meanwhile on the ground, a new Soyuz crew is getting ready for its launch next month to the orbital laboratory.
The orbiting crew took part in studies observing how the human body adapts to weightlessness during long duration missions in space. Scientists are looking at how astronauts interact with touch-based technologies and repair sensitive equipment for the Fine Motor Skills experiment. The crew also participated in ultrasound scans for the Sprint study to help doctors explore new experiment techniques for improving crew productivity.
A pair of cosmonauts are getting the station’s Russian segment and their tools ready for Monday’s six-hour spacewalk. They will replace external experiments and photograph the exterior condition of the Russian modules.
Back on Earth, three new Soyuz crew members are conducting mission simulations before their departure to the Baikonur Cosmodrome launch site on Aug. 18. Soyuz Commander Sergei Volkov and Flight Engineers Andreas Mogensen and Aidyn Aimbetov will launch aboard the Soyuz TMA-18M spacecraft Sept. 2.
Two cosmonauts are getting ready for a six-hour spacewalk coming up Monday morning. Six days later Japan will launch its fifth resupply mission to the International Space Station. Both events will be covered live on NASA Television.
