NASA International Space Station On-Orbit Status 3 May 2016


NASA International Space Station On-Orbit Status 3 May 2016.

Today, the crew is observing how the lack of gravity affects plants and rodents. NASA is using the observations to improve the health of astronauts in space and humans on Earth.

The crew is stowing plant samples harvested for the Plant Gravity Sensing botany study to understand how roots sense gravity. The samples are being inserted into a science freezer for return to Earth aboard the SpaceX Dragon next week. Results may help astronauts grow their own food while living in space.

Rodents are also being observed in a habitat designed to house them in space. The Rodent Research-3 experiment is studying how space changes the musculoskeletal system and if an antibody that prevents muscle weakening on Earth works in space.

Dragon is still being loaded with gear and science for analysis on the ground. The private space freighter will be removed from the Harmony module and released from the Canadarm2 robotic arm for a splashdown in the Pacific Ocean May 11.

On-Orbit Status Report

Rodent Research-3 (RR-3) Transfer and Grip Strength Operations: The crew transferred rodents from their habitats to the Microgravity Science Glovebox (MSG) and completed grip strength measurements. Operations were completed ahead of schedule and was the first time on-orbit use of the Grip Meter. This was the first of three RR-3 sessions conducted this week that will study the molecular and physical changes to the musculoskeletal system that happen in space. Results will expand scientists' understanding of muscle atrophy and bone loss in space while testing an antibody that has been known to prevent muscle wasting in mice on Earth.

Fluid Shifts Baseline Imaging in the Russian Segment Preparation: The crew gathered and transferred hardware from the US Segment to the Russian Segment and configured Ultrasound 2 hardware in the Service Module to support Fluid Shifts data collections while the crewmember is wearing Chibis Lower Body Negative Pressure (LBNP) device. Fluids Shift is divided into three one-week segments: Dilution Measures, Baseline Imaging, and Baseline Imaging using the Russian Chibis. The experiment measures how much fluid shifts from the lower body to the upper body, in or out of cells and blood vessels, and determines the impact these shifts have on fluid pressure in the head, changes in vision and eye structures.

Plant Gravity Sensing-3 (PGS-3) Closeout: Following yesterday's successful PGS-3 Sample Fixation operations, today the Chemical Fixation Apparatus samples were inserted into the Minus Eighty Laboratory Freezer for ISS (MELFI) in preparation for return on SpaceX-8. This concludes a two week Japan Aerospace Exploration Agency (JAXA) PGS-3 experiment run which studies whether plants grown in microgravity conditions can sense the changes in the gravitational acceleration and the concentrations of calcium in plant cells changes. Gravity is a critical environmental factor affecting the morphology and functions of organisms on Earth.

Radiation Dosimeter inside ISS-Neutron (RaDI-N): After retrieving the RaDI-N hardware from the Russian crewmember, the USOS crew deployed all 8 Space Bubble Detectors in various locations in the ISS for the Radi-N2 experiment. The Canadian Space Agency (CSA) investigation is conducted by measuring neutron radiation levels while onboard the ISS. RaDI-N uses bubble detectors as neutron monitors which have been designed to only detect neutrons and ignore all other radiation.

Dose Tracker: The crew configured the Dose Tracker app and completed entries for medication tracking. This investigation documents the medication usage of crew members before and during their missions by capturing data regarding medication use during spaceflight, including side effect qualities, frequencies and severities.

Habitability Human Factors Directed Observations: The crew recorded and submitted a walk-through video documenting observations of an area or activity providing insight related to human factors and habitability. The Habitability investigation collects observations about the relationship between crew members and their environment on the ISS.

Intra-module Ventilation (IMV) Reconfiguration: Yesterday, in an effort to reduce ppCO2 levels, ground commanding was performed to implement split ventilation between the USOS and Russian segments. The system has not yet reached a steady state, however, ppCO2 is trending lower than the Node 3 CDRA/Vozdukh combination was able to support in the previous configuration. Teams continue to monitor CO2 closely as they characterize the new configuration.

Alpha Magnetic Spectrometer (AMS) Survey: Robotics Ground Controllers are currently making preparations to survey the AMS using various cameras from various Space Station Remote Manipulator System (SSRMS)/Special Purpose Dexterous Manipulator (SPDM) positions. The survey is being performed to understand the state of the payload as well as to obtain detailed views of the payload. Following the survey SPDM will be stowed on Mobile Base System 2 (MBS 2) and SSRMS will be maneuvered to a translate configuration.

Dragon Cargo Transfer Status: The crew has completed ~34.5 hours of cargo transfer with ~13.5 hours remaining to be completed.
