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 …

On March 30, 2019, Parker Solar Probe begins the second solar encounter phase of its mission, culminating in its closest approach to the Sun, called perihelion, on April 4 at 6:40 p.m. EDT.

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 …

A pair of astronauts are trading places on the next two spacewalks as the Expedition 59 crew continues upgrades and maintenance outside of the International Space Station. The orbital residents are also conducting space research to improve life for humans on and off Earth. NASA announced Monday that Flight Engineer Nick Hague is joining fellow …

With the first in a series of three spacewalks successfully completed at the International Space Station, NASA has updated astronaut assignments for the remaining two spacewalks and will preview the third in an upcoming news conference on NASA Television and the agency’s website. NASA astronauts Nick Hague and Anne McClain conducted the first spacewalk in this series on March 22. Hague …

Materials Science Laboratory (MSL): The crew opened the Gas Supply Drawer valve on the Material Science Research Rack (MSRR)/MSL which is used for basic materials research in the microgravity environment of the ISS. The MSL can accommodate and support diverse Experiment Modules. In this way, many material types, such as metals, alloys, polymers, semiconductors, ceramics, …

USOS Extravehicular Activity (EVA) #52: Today Anne McLain (EV-1) and Nick Hague (EV-2) exited the Joint Airlock and performed US EVA #52 (Lithium Ion Battery R&R EVA #1) with a Phased Elapsed Time (PET) of 6h 39m. The primary purpose of this EVA was to facilitate the installation of new P4 Li-Ion batteries and completed …
