Bio-Monitor: A crewmember doffed and stowed the BioMonitor hardware. Although the ISS is equipped with health and life sciences research tools, the existing instrumentation for continuous and simultaneous recording of several physiological parameters is lacking. To tackle this issue, the Bio-Monitor Commissioning activity tests the Bio-Monitor facility; a wearable garment capable of monitoring relevant physiological parameters for up to 48 hours in a non-invasive and non-interfering way. The physiological parameters which can be monitored consist of heart rate, respiration rate, ECG (Electrocardiogram), skin temperature, peripheral blood oxygen saturation, etc.

Space Pup: SpacePup samples were stowed on SpX-17 for return. Space Pup represents the first step toward studying the effects of space radiation on mammalian reproduction which must be understood to sustain life beyond Earth.

Veg-04A: The crew filled out the Profile of Mood questionnaire in reference to the VEG-04 activities. The Pick-and-Eat Salad-Crop Productivity, Nutritional Value, and Acceptability to Supplement the ISS Food System (Veg-04A, Veg-04B, and Veg-05) investigation is a phased research project to address the need for a continuous fresh-food production system in space. A healthy, nutritious diet is essential for long-duration exploration missions, which means that the typical pre-packaged astronaut diet needs to be supplemented by fresh foods during flight; the Veggie Vegetable Production System (Veggie) has begun testing aboard the space station to help meet this need, and validation tests have demonstrated that leafy greens can be grown in spaceflight. The research of Veg-04A focuses on the impact of light quality and fertilizer on leafy crop growth for a 28-day grow-out, microbial food safety, nutritional value, taste acceptability by the crew, and the overall behavioral health benefits of having plants and fresh food in space.

Photobioreactor: The crew installed a software update to the Photobioreactor hardware. Today the life support systems that sustain astronauts in space are based on physicochemical processes. The Photobioreactor investigation aims at demonstrating that microalgae (i.e. biological processes) can be used together with existing systems to improve recycling of resources, creating a hybrid life support system. This hybrid approach could be helpful in future long-duration exploration missions, as it could reduce the amount of consumables required from Earth, and will first be tested in space on the ISS.

Max Cycle Ergometer with Vibration Isolation and Stabalization (CEVIS): FE-5 and FE-6 completed Max CEVIS tests today. This test is used by the medical community to evaluate astronauts’ aerobic fitness. It is performed three times per increment.
