April is shaping up to be a busy month bringing three new spaceships and another spacewalk to the International Space Station. The Expedition 59 crew has already wrapped up two spacewalks this year and welcomed the first SpaceX Crew Dragon spacecraft and the latest Soyuz MS-12 crew ship in March. Roscosmos, SpaceX and Northrop Grumman …
Extravehicular Activity (EVA) #53: Today, Nick Hague, as EVA Crewmember (EV)-1, and Christina Koch, as EV-2, performed US EVA #53 (Lithium Ion Battery R&R EVA #2) with a Phased Elapsed Time (PET) of 6 hours 45 minutes. The second of two planned battery replacement EVAs, today’s EVA completed the installation of the new batteries brought …
Expedition 59 Flight Engineers Nick Hague and Christina Koch of NASA concluded their spacewalk at 2:27 p.m. EDT. During the six hour and 45-minute spacewalk, the two NASA astronauts successfully connected three newer, more powerful lithium-ion batteries to replace the previous six nickel-hydrogen batteries that provide power for one channel on one pair of the station’s solar arrays. The new …
NASA astronauts Nick Hague and Christina Koch have begun the second spacewalk in a week to complete the installation of new batteries to upgrade the International Space Station’s power capability. The duo from the Expedition 59 crew switched their spacesuits to battery power at 7:42 a.m. EDT to begin the estimated six-and-a-half hour spacewalk. Watch the spacewalk on NASA TV and on the agency’s website. …
Team Task Switching (TTS): Today the crew completed a TTS survey. The objective of the TTS investigation is to gain knowledge about whether or not crewmembers have difficulty in switching tasks, and apply the results to both the reduction of any negative consequences and improvement of individual and team motivation and effectiveness. Mobile Servicing System …
Expedition 59 Flight Engineers Nick Hague and Christina Koch will exit the Quest airlock Friday for about 6.5 hours of battery swaps to upgrade the station’s power storage capacity. The duo will set their spacesuits to battery power about 8:20 a.m. EDT Friday signifying the start of their spacewalk. Coverage will begin its live coverage at 6:30 a.m. Watch the spacewalk on NASA TV and on the agency’s …
Astronauts Nick Hague and Christina Koch have configured their spacesuits and reviewed procedures for tomorrow’s spacewalk at the International Space Station. Robotics controllers also readied the Port-4 (P4) truss structure so the spacewalkers can continue battery swaps and power upgrades outside the orbital lab. Hague and Koch will set their spacesuits to battery power Friday …
Cerebral Autoregulation: The crew performed data measurements for the Cerebral Autoregulation experiment and closed out the hardware. As the body’s most important organ, the brain needs a strong and reliable blood supply, so the brain is capable of self-regulating blood flow even when the heart and blood vessels cannot maintain an ideal blood pressure. The …
Two days away from the second International Space Station spacewalk of 2019 and the Expedition 59 crew is studying the human brain and an astronaut’s wake-sleep cycle in space. Flight Engineers Nick Hague and Christina Koch will exit the Quest airlock Friday for about 6.5 hours of battery swaps to upgrade the station’s power storage …
Radiation Dosimetry Inside ISS-Neutrons (RADI-N2): The crew retrieved a donned sensor and handed over to the Russian crew for data retrieval. Another unit was also relocated to the crew quarters sleeping area. The objective of this Canadian Space Agency investigation is to better characterize the ISS neutron environment, define the risk posed to the crew …
