NASA Space Station On-Orbit Status 22 April 2019 - New Scientific Research to Start.

The Expedition 59 crew has been unpacking Northrop Grumman's Cygnus cargo craft over the weekend and began science operations on the newly delivered space research.

The 17th SpaceX Dragon mission is now due to launch next week to replenish the International Space Station.

Three NASA astronauts and one Canadian Space Agency astronaut split the workday measuring the mass of 40 mice shipped to the station aboard Cygnus last week. Flight Engineers Anne McClain and Christina Koch started the first half of the day with Flight Engineers Nick Hague and David Saint-Jacques wrapping up the rodent research work in the afternoon. The quartet used the mass measurement device inside the Life Sciences Glovebox beginning the study to learn how microgravity impacts the immune system.

The SpaceX Dragon cargo craft is due to join the five other spacecraft parked at the station after it launches from Florida April 30. Dragon is scheduled to arrive May 2 and Saint-Jacques will command the Canadarm2 robotic arm to reach out and capture the cargo vessel. Dragon will deliver over 5,000 pounds of new science, supplies and hardware to the orbital lab.

Cosmonauts Oleg Kononenko and Alexey Ovchinin stayed focused on the Russian side of the station with their complement of orbital science and lab maintenance. Commander Kononenko updated communications gear, cleaned fans and filters and explored enzyme behaviors. Flight Engineer Ovchinin offloaded cargo from the new Progress 72 resupply ship and studied radiation exposure.

On-Orbit Status Report

Treadmill 2 (T2) Mechanical Issues and False Fire: During a T2 session this morning, the crew reported that the belt slowed dramatically, a grinding noise was heard, and the T2 Smoke Detector triggered a fire alarm. Air measurements confirmed this to be a false fire event and investigation by the crew confirmed that the T2 slats are not square with the T2 closeout panel. T2 remains No-Go for use at this time. Ground teams are reviewing additional imagery of the hardware and will hold meetings this afternoon to discuss their findings.

NanoRacks Platforms: Over the weekend, a crewmember installed Module 78 onto NanoRacks Platform 1 and removed Module 77. NanoRacks Platforms is a multipurpose research facility on board the International Space Station (ISS). NanoRacks Platforms supports NanoRacks Modules in the CubeSat form factor by providing power and data transfer capabilities to operate investigations in microgravity.

Space Tango MultiLab Locker (TangoLab-1): Over the weekend, a crewmember installed a new sample CardCube in the TangoLab-1 facility. TangoLab-1 is a reconfigurable general research facility designed for microgravity research and development and pilot manufacturing aboard the ISS.

Rodent Research-12 (RR-12): Today, crewmembers transferred 40 mice from the Cygnus spacecraft into the ISS Rodent Habitats. RR-12, Tetanus Antibody Response by B cells in Space (TARBIS), examines the effects of spaceflight on the function of antibody production and immune memory. Spaceflight is known to have a dramatic influence on immune response, but there is little research on its effect following an actual challenge to the body's immune system. Using a mouse model makes this possible, as the mouse immune system closely parallels that of humans.

Radiation Dosimetry Inside ISS-Neutrons (RADI-N2): Today, a crewmember retrieved 2 temporarily stowed dosimeters for deployment in crew quarters and the other to be donned for 7 days. Six dosimeters were retrieved from a Russian crewmember and were deployed in the Cupola. The objective of this Canadian Space Agency (CSA) investigation is to better characterize the ISS neutron environment, define the risk posed to the crew members' health, and provide the data necessary to develop advanced protective measures for future spaceflight. It has been recognized that neutrons make up a significant fraction (10-30%) of the biologically effective radiation exposure in low-Earth orbit. The bubble detectors used in the investigation are designed detect neutrons and ignore all other radiation.

Fluid Shifts: Today, a crewmember performed the Dilution Measures setup in preparation of blood, urine, and saliva collections. The purpose of this study is to characterize fluid distribution and compartmentalization associated with long-duration space flight, and to correlate these findings with vision changes and other elements of the Spaceflight Associated Neuro-ocular (SANS) syndrome.

POLAR: Today, a crewmember activated and checked out POLAR 6 and 8. POLAR is a Cold Stowage managed facility that provides transport and storage of science samples at cryogenic temperatures (-80ºC) to and from the ISS.

Spaceborne Computer: Today, Spaceborne Computer was deactivated by ground controllers and therefore completing its experiment and will be de-installed and stowed. Spaceborne Computer's goal is to run a yearlong experiment of high performance commercial off-the-shelf (COTS) computer systems on the ISS. During high radiation events, they intend to verify if the systems can still operate correctly by lowering their power, and therefore, speed. This research helps scientists identify ways of using software to protect ISS computers without expensive, time-consuming or bulky protective shielding.

Thermal Amine System: Today, the crewmembers completed preliminary steps for the new Thermal Amine System, which arrived on NG-11. Thermal Amine System tests a method to remove carbon dioxide (CO2) from air aboard the ISS, using actively heated and cooled amine beds. Controlling CO2 levels on the station reduces the likelihood of crewmembers experiencing symptoms of CO2 buildup, which include fatigue, headache, breathing difficulties, strained eyes, and itchy skin. The system includes elements that reduce loss of water vapor, and recover CO2 for use in electrolysis to produce oxygen.

Northrop Grumman 11 (NG-11) Cygnus Cargo Operations: After Friday's successful berthing of NG-11, the crew ingressed the vehicle and started unloading cargo; since then, the crew has completed approximately 17 hours of cargo operations. Ground teams estimate ~20 hours of cargo operations remain to completely unload the vehicle of the newly arrived equipment and science.

Waste and Hygiene Compartment (WHC) Urine Receptacle Remove and Replace (R&R): Today, the crew removed and replaced the WHC Urine Receptacle and Insert Filter. After replacement, a functionality test of the WHC was performed and the WHC was declared operational.
