ISS - Expedition 61 Mission patch.
January 24, 2020
The Expedition 61 astronauts are ready to finish repairing the Alpha Magnetic Spectrometer (AMS) after wrapping up their spacewalk preparations today. The International Space Station residents today also had time to explore what microgravity is doing to their muscles and digestive system.
Astronauts Andrew Morgan and Luca Parmitano have readied the U.S. spacesuits they will wear for about six hours and thirty minutes beginning Saturday at 6:50 a.m. EST. They will finalize the complex thermal repairs on the AMS, a dark matter and antimatter detector, installed in 2011 on the Starboard-3 truss structure.

Morgan and Parmitano were joined by NASA Flight Engineers Jessica Meir and Christina Koch for a final procedures review with mission controllers on the ground. Meir and Koch will operate the Canadarm2 robotic arm carefully making fine-tuned maneuvers to assist the spacewalkers at the AMS worksite.
Meir and Koch began their workday by performing scans of their neck, arm, leg and feet muscles with an ultrasound device. The scans are downlinked to doctors studying how weightlessness affects the biochemical properties of muscles. The pair also collected their blood samples and stowed them in a science freezer for the human research study. Insights my impact health strategies on future long-term space missions.

Cosmonauts Alexander Skvortsov and Oleg Skripochka spent Friday morning on a Russian digestion study today scanning their stomachs with another ultrasound device before and after breakfast. They split up in the afternoon working on a variety of station hardware maintenance and crew departure activities.
