The Expedition 61 astronauts have one more spacewalk planned this weekend and they will finish the repair of a cosmic ray detector. This will be the ninth spacewalk for the crew, more than in any other increment in the history of the International Space Station.

NASA astronauts Jessica Meir and Christina Koch have turned their attention from Monday's spacewalk to help two crewmates going on a very different spacewalk on Saturday. The pair completed a spacewalk yesterday upgrading power systems on the Port-6 truss structure.

Spacewalkers Andrew Morgan and Luca Parmitano of ESA (European Space Agency) will finalize thermal repairs on the Alpha Magnetic Spectrometer (AMS) on Saturday. The AMS, installed in 2011 on the Starboard-3 truss structure, is an astrophysics device searching for evidence of dark matter and antimatter.

The duo will set their U.S. spacesuits to internal power Saturday at 6:50 a.m. EST signifying the official start of their spacewalk. NASA TV begins its live broadcast of the planned six-hour AMS repair excursion at 5:30 a.m.

Meir and Koch will be getting up to speed this week with the Canadarm2 robotics procedures necessary to assist Morgan and Parmitano during Saturday's spacewalk. The quartet gathered together Tuesday afternoon and began reviewing the spacewalk plan with specialists in Mission Control.

On-Orbit Status Report

Food Acceptability: The crew completed a Food Acceptability Survey using the Data Collection Tool on an SSC (Station Support Computer). This investigation seeks to determine the impact of repetitive consumption of food currently available from the spaceflight food system. Results will be used in developing strategies to improve food system composition to support crew health and performance on long duration missions.

Plasma Kristal-4: The crew took photos of the system and packed the hard drives for return on 59-Soyuz. Plasma Krystall-4 (PK-4) is a scientific collaboration between the European Space Agency (ESA) and the Russian Federal Space Agency (Roscosmos), performing research in the field of "Complex Plasmas": low temperature gaseous mixtures composed of ionized gas, neutral gas, and micron-sized particles. The micro-particles become highly charged in the plasma and interact strongly with each other, which can lead to a self-organized structure of the micro-particles: so-called plasma crystals. Experiments in the facility aim to study Transport Properties, Thermodynamics, Kinetics and Statistical Physics, and Non-linear waves and Instabilities in the plasmas.

Standard Measures (SM): The crew performed the sample collections and survey for the continuing SM investigation. The aim of the SM investigation is to ensure consistent capture of an optimized, minimal set of measures from crewmembers until the end of the ISS Program in order to characterize the adaptive responses to and risks of living in space. Among other things, the ground teams perform analyses for metabolic and chemistry panels, immune function, microbiome, etc.

Systems:

AMS-02 (Alpha Magnetic Spectrometer) EVA preparation: Today, the crew continued preparations for the final AMS repair EVA by reviewing their AMS EVA procedures. The multiple AMS-02 repair EVAs are being performed to recover the cooling pumps within the AMS-02 experiment. AMS-02 is a state-of-the-art particle physics detector that uses the unique environment of space to advance knowledge of the universe and lead to the understanding of the universe's origin by searching for antimatter, dark matter and measuring cosmic rays.
