NASA Space Station On-Orbit Status 2 March 2017

The International Space Station fired its engines Wednesday night slightly raising its orbit to accommodate a crew exchange in April. In the meantime, the six-person Expedition 50 crew continued learning how living in space affects the human body.

The station's third module, the Zvezda service module which launched in 2000, fired its main engines for 43 seconds overnight. The orbital reboost places the station at the correct altitude for the departure of three Expedition 50 crew members April 10. Just ten days later, two new space residents will arrive completing the Expedition 51 crew.

Scientists are exploring the best nutrition requirements to keep astronauts healthy and productive during long-term space missions. Astronaut Thomas Pesquet is contributing to that research today beginning a prescribed diet for the next 11 days. During that period he will collect urine samples and measure his breathing for the Energy study. Results will help researchers plan meals to ensure successful missions farther out into space.

Flight Engineer Peggy Whitson, who will become station commander April 9, peered at stem cells through a specialized microscope on today. She is helping scientists understand how microgravity increases stem cell replication possibly improving disease treatments on Earth.

On-Orbit Status Report

Lab Carbon Dioxide Removal Assembly (CDRA) Maintenance: Yesterday the crew installed the newer generation beds, like those in Node 3 CDRA, into Lab CDRA. Today, the crew repaired the CDRA Valve Power Cable W9P12 by splicing in two new wire segments and performing a 120V power check of the connector prior to installing CDRA into the LAB AR Rack. Initial CDRA power and data checkout was nominal. The full Lab CDRA checkout is in work.

Pressurized Mating Adaptor (PMA) 3 Ingress Prep: The crew is scheduled to ingress the PMA3 tomorrow morning. Today the crew reviewed the PMA3 ingress procedure and gathered required hardware for tomorrow's activities.

Energy Requirements for Long-Term Space Flight (Energy): Today is Day 1 for the Energy investigation; yesterday the subject began the 11 day diet and today began the urine collection for both the subject and control subject. This morning, the subject configured the Pulmonary Function System (PFS) and performed a series of Oxygen Uptake Measurements (OUMs) after prescribed meals and scheduled fluid collections. The Energy investigation measures adaptations in the components of total energy expenditure of crewmembers, so that an equation to determine the energy requirements of crewmembers during space flight may be derived. Such knowledge of energy requirements is of a great importance to ensure health, good performance and the overall success of a mission, and also contributes to ensure adequate exercise load and cargo allotments for food during space flight.

Advanced Plant Experiments (APEX)-04 Photo: The crew retrieved one of the APEX-04 petri plates and photographed it on the Advanced Biology Research Facility (ABRS) photogrid. The picture will be downlinked for ground teams to evaluate the growth status. The APEX-04 (Epigenetic change in Arabidopsis thaliana in response to spaceflight - differential cytosine DNA methylation of plants on the ISS) experiment investigates how spaceflight can affect an organism on a molecular level without altering its outward appearance. Previous research has demonstrated that large numbers of plant genes are expressed differently in space compared to plants on Earth, which can alter how plants grow. This investigation studies the entire genome of thale cress plants grown in space, creating maps of spaceflight-specific changes in certain groups of genes. Results give new insight into plants' molecular responses to spaceflight, which benefits efforts to grow plants in space for food and oxygen.

Microgravity Expanded Stem Cells (MESC) Microscope Operations: The crew removed a BioCell from the Space Automated Bioproduct Laboratory-2 (SABL2) and placed it on the microscope stage configured outside the Microgravity Science Glovebox (MSG). The crew worked with ground specialist to image areas of the BioCell plate. Following the focused imaging, the crew reinserted the BioCell back into the SABL. MESC will aid researches determine the efficiency of using a microgravity environment to accelerate expansion (replication) of stem cells for use in terrestrial clinical trials for treatment of disease.

ISS Reboost: Last night the ISS performed a nominal reboost using the SM main engines, TIG 061/03:10 GMT burn duration 43 seconds. The reboost set up the planned conditions for the upcoming landing of 48S on 10-April and launch of 50S on 20-April 20. The 50S launch will utilize the 4-orbit rendezvous.

Mobile Servicing System (MSS) Operations: Robotics operations for Stratospheric Aerosol and Gas Experiment (SAGE) Instrument Panel (IP) extraction from the SpX-10 Dragon Trunk have begun.
