ISS – Expedition 69 Mission patch.
Might 19, 2023
Crew members aboard the Worldwide Area Station carried out scientific investigations in the course of the week of Might 15 that included finding out the conduct of protein options, testing know-how to watch astronaut sleep high quality, and inspecting the impact of train regimens that don’t embrace a treadmill.
Listed here are particulars on a few of the microgravity investigations presently happening aboard the orbiting lab:
Liquids, Uncontained

Ring Sheared Drop-IBP, sponsored by the ISS Nationwide Lab, research high-concentration protein options and checks laptop fashions for predicting their conduct. The investigation makes use of a system with out containers that removes the consequences of interactions with stable partitions. Outcomes might result in extra correct fashions of complicated fluid conduct, enabling manufacturing of next-generation medicines and bettering in-space manufacturing and 3D printing. Outcomes additionally might assist streamline pharmaceutical manufacturing, 3D printing, meals processing, and different processes on Earth. Through the week, crew members put in pattern syringes and deployed drops into the system for processing.
Sleep, Improved

Inadequate sleep and sleep problems can impair efficiency and improve the chance of medical issues resembling heart problems. Goals, an investigation from ESA (European Area Company), demonstrates a wearable headband to watch astronaut sleep high quality throughout spaceflight. Sleep circumstances for astronauts may be traumatic and monitoring their sleep high quality is troublesome with the gadgets presently out there. This machine collects a wide range of knowledge together with sleep length, levels, and variety of awakenings and coronary heart fee. The straightforward-to-use device additionally might assist enhance sleep for individuals on Earth. Crew members wore the headscarf for a number of classes in the course of the week.
Train, Examined
Missions to the Moon and Mars want to incorporate train gadgets that present a wide range of cardio and resistance choices to take care of astronaut well being and bodily health and in addition meet launch weight and mass limits. Treadmills presently used to strengthen the motor sample of strolling in astronauts are too cumbersome and heavy for future long-term missions. Zero T2 examines the consequences on bone, muscle, and cardio well being and efficiency when crew members don’t train on a treadmill throughout flight. Outcomes might assist decide whether or not different train regimens are enough to take care of bodily well being on future missions. Crew members exercised on the Superior Resistive Train Gadget (ARED) in the course of the week for the investigation.

Different Investigations Involving the Crew:
– College students write software program to regulate the house station’s Astrobee free-flying robots for Zero Robotics. The expertise helps encourage the following era of scientists, engineers, and explorers.

– ISS Ham Radio gives college students, lecturers, and others the chance to speak with astronauts utilizing novice radio items. Earlier than a scheduled name, college students study in regards to the station, radio waves, and different subjects, and put together an inventory of questions primarily based on the subjects they’ve researched.

– Area Well being, an investigation from CSA (Canadian Area Company), makes use of the wearable Bio-Monitor system built-in with the automated Artemis platform to evaluate the impact of house journey on coronary heart well being. Automated monitoring methods are wanted as future missions journey farther from medical help.

– Airborne Particulate Monitor (APM) demonstrates an instrument to measure the focus of particles within the house station’s air. Sustaining air high quality within the house station is important for crew member well being, however no functionality presently exists to confirm that most allowable concentrations of particles are met.
