Lab Tests and Life Science as Station Orbits Higher Today

Mark Garcia
Posted Apr 18, 2018 at 12:29 pm


Mexico, Baja California and the southern coast of the state of California are pictured as the International Space Station orbited above the Pacific Ocean.

A docked Russian cargo craft automatically fired its engines this morning boosting the International Space Station's altitude a little higher. During the rest of the day, the Expedition 55 crew supported life science and swapped out station hardware.

Спойлер

Russia's Progress 69 resupply ship docked to the Zvezda service module fired its thrusters boosting the station's orbit today. The two-minute, six-second burn establishes the correct orbit when three crew members undock and land in June and a two-orbit rendezvous capability for the Progress 70P resupply craft when it launches in July.

NASA crewmates Scott Tingle, Ricky Arnold and Drew Feustel became lab assistants today as they collected and stowed their own blood, urine and saliva samples in a science freezer. Two long-running human research experiments, Biochemical Profile and Repository, are basing their results on the analysis of these samples helping scientists understand how microgravity impacts the human body.

Tingle later tested the Miniature Exercise Device-2 for providing a range of motion and resistance exercise while taking up less space aboard the station. Feustel installed new firewall gear in the Harmony module before replacing manifold bottles in the Combustion Integrated Rack. Arnold worked with commercial science hardware then processed samples for a protein crystal growth student experiment.

Mice are being observed on the orbital lab today to understand the physiological signals that lead to muscle and bone loss in space. Norishige Kanai from the Japan Aerospace Exploration Agency collected blood samples from the mice to be processed, analyzed and stowed in a science freezer. Scientists are studying the effectiveness of a drug therapy to prevent those stresses and signals that cause weakened bones and muscles.

Hardware acceleration boosts science on the ISS
16 April 2018



Electronics upgrade for the Electro-Magnetic Levitator - More experiments in less time

Friedrichshafen, 16/04/2018 - German astronaut Alexander Gerst will set-up the HSC-OS (High Speed Camera Operating System), a small but powerful electronic upgrade to control the Electro-Magnetic Levitator's (EML) high-speed video camera and rapidly process the enormous volume of data it generates. Airbus has developed this component on behalf of the German Aerospace Center´s (DLR) Space Administration. This science "booster" - scheduled for launch with Orbital Antares 9 Mission - will be integrated into the EML facility on board the ISS during the European Space Agency's Horizons mission, which will last until the end of 2018.

Спойлер

Airbus´ new concept uses advanced commercial microcomputer boards, that were specially adapted and qualified for use in Space, increasing the transfer speed from the camera to the computer system by a factor of 10. Moreover, a special hardware-based data compressor, integrated in the commercial microcomputer, replaces the previous, software-based concept, reducing compression times by factors of 60 or more. Both measures significantly increase the data throughput of the system.

The Electro-Magnetic Levitator is a much lauded experimental facility in the Columbus laboratory of the ISS. Funded by ESA and DLR´s Space Administration, it was developed and built by Airbus. It was launched on board the ATV-5 in August 2014, and Alexander Gerst installed the EML during his first stay on the ISS in autumn 2014. Now Gerst is also scheduled to install the data electronics this summer – an important enhancement to the EML that will enable the researchers to pursue scientific excellence with even greater efficiency.

The EML

This facility aids researchers in conducting scientific experiments on small metal samples, allowing them to determine important material parameters with extreme precision. These, in turn, are crucial for optimising industrial manufacturing processes on Earth, to produce better metallic materials with customised properties.

Metal samples are melted and heated to temperatures of up to 2,100 degrees Celsius and measurements are taken in the molten state. Samples are then solidified in a controlled manner. As hot molten metals are extremely chemically reactive, each sample is processed containerlessly by placing it without a crucible in an electromagnetic field, causing them to be positioned and heated by induction. All measurements must therefore also be taken using non-contact optical methods.

The EML's sophisticated measurement and processing technology also includes a high-speed video camera that films these rapid processes, on the levitating molten metal sample, at more than 30,000 frames per second.

Since operations commenced, many experiments have been conducted (>1,200 cycles of melting and solidifying) and enormous volumes of data collected (>13 TB) – mainly video data.

"It became apparent fairly soon after commissioning that the mission capacity is dependent on the time it takes to process the huge amounts of high-speed video data," said Wolfgang Soellner, who is responsible for EML experiment design at Airbus. "This was due to an enhanced utilisation concept that produces significantly more data than the mission studies had planned for. The upgraded video data processing will eliminate this bottleneck in the experimental procedure."

Materials science relies on repeating experiments numerous times with slightly altered settings, so accelerated experimental procedures are of central importance to achieving timely scientific results.

Doha, the capital city of Qatar, was photographed as the space station orbited over the northeastern coast of the Arabian Peninsula.

Biomedical research to improve health on Earth and in space dominated today's science activities aboard the International Space Station. The Expedition 55 crew is helping scientists from around the world understand how life shaped by gravity adapts to living in outer space.

Спойлер

NASA astronauts Ricky Arnold and Drew Feustel joined forces today collecting and stowing their blood samples in a science freezer for a pair of human research studies. The samples will be analyzed later to detect the chemical responses and physiological changes that take place in the human body during a spaceflight mission.

Blood samples were also drawn from mice as Japanese astronaut Norishige Kanai continued his week-long research activities for the Mouse Stress Defense experiment. Those samples will be processed in centrifuge, stowed in a freezer then analyzed to detect the processes that lead to muscle and bone loss in microgravity. Astronauts could benefit from the results and stay healthier on longer missions farther into space.

Exercise is a very important contributor to maintaining stronger bones and muscles in space. However, exercise devices are bulky and can impact spacecraft habitability. Arnold tested a newer, smaller device today called the Miniature Exercise Device-2 that provides a range of motion and resistance workouts while maximizing habitable spacecraft volume.

NASA astronaut Scott Tingle tends to plants grown inside the VEGGIE facility in support of space botany research.

The outside of the International Space Station is a harsh environment but scientists are taking advantage of the extreme conditions to conduct advanced space research. Astronauts are also researching what happens to a variety of organisms living for months at a time inside a spacecraft as NASA prepares for longer missions farther out into space.

Спойлер

The fifth and final external materials experiment (MISSE) delivered by the latest SpaceX Dragon resupply ship was activated outside the orbital lab today. Robotics engineers operating the Canadarm2 and Dextre extracted and installed the MISSE canisters one by one from Dragon's trunk to areas on the station. The canisters were then remotely opened exposing a variety of materials to the vacuum of space to help engineers design safer and stronger spacecraft systems.

Back inside the orbital lab, Flight Engineer Scott Tingle of NASA harvested and photographed plants for the APEX-06 study today. The botanical samples collected from the VEGGIE facility were later processed and stowed in a science freezer for return to Earth inside the Dragon cargo craft. They will be analyzed after being quickly shipped to scientists at NASA and the University of Wisconsin.

NASA Flight Engineers Ricky Arnold and Drew Feustel once again partnered up and collected their blood and urine samples today for more biomedical experiments. Researchers are analyzing the samples as they continuously study how the human body adapts to extended periods of weightlessness. Results will help doctors provide therapies to maintain the health of astronauts in space and humans on Earth.

Mice are also being observed on the space station so scientists can detect the chemical signals that lead to weakened bones and muscles. Japanese astronaut Norishige Kanai drew more blood samples from the rodents today and wrapped up a week-long run of the Mouse Stress Defense experiment. The blood samples will be processed in a centrifuge, stowed in biological science freezer then returned to Earth inside Dragon for analysis on Earth.
