Human Research Program (Biochemical Profile, Marrow, and Repository):

Спойлер

This morning a 55S crewmember collected blood samples for their Flight Day 15 session of the Biochem Profile and Repository investigations and their Flight Day 10 session of CSA's Marrow investigation. They also collected air samples yesterday and today. 

[/li]
• The Biochemical Profile investigation tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results; which scientists can use to study the effects of spaceflight on the body.
• Marrow looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow.
• Repository is a storage bank used to maintain biological specimens over extended periods of time and under well-controlled conditions. The repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions.

New NASA Mission to Detect Plant Water Use from Space

Doctors learn a lot about their patients' health by taking their temperature. An elevated temperature, or fever, can be a sign of illness. The same goes for plants, but their temperatures on a global scale are harder to measure than the temperatures of individual people.

That's about to change, thanks to a new NASA instrument that soon will be installed on the International Space Station called ECOSTRESS, or ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station. ECOSTRESS will measure the temperature of plants from space. This will enable researchers to determine plant water use and to study how drought conditions affect plant health.

Спойлер

Plants draw in water from the soil, and as they are heated by the Sun, the water is released through pores on the plants' leaves through a process called transpiration. This cools the plant down, much as sweating does in humans. However, if there is not enough water available to the plants, they close their pores to conserve water, causing their temperatures to rise.

Plants use those same pores to take up carbon dioxide from the atmosphere for photosynthesis - the process they use to turn carbon dioxide and water into the sugar they use as food. If they continue to experience insufficient water availability, or "water stress," they eventually starve or overheat, and die.

ECOSTRESS data will show these changes in plants' temperatures, providing insight into their health and water use while there is still time for water managers to correct agricultural water imbalances.

"When a plant is so stressed that it turns brown, it's often too late for it to recover," said Simon Hook, ECOSTRESS principal investigator at NASA's Jet Propulsion Laboratory in Pasadena, California. "But measuring the temperature of the plant lets you see that a plant is stressed before it reaches that point."

These temperature measurements are also considered an early indicator of potential droughts. When plants in a given area start showing signs of water stress through elevated temperature, an agricultural drought is likely underway. Having these data in advance gives the agricultural community a chance to prepare and/or respond accordingly.

"ECOSTRESS will allow us to monitor rapid changes in crop stress at the field level, enabling earlier and more accurate estimates of how yields will be impacted," said Martha Anderson, an ECOSTRESS science team member with the U.S. Department of Agriculture in Beltsville, Maryland. "Even short-term moisture stress, if it occurs during a critical stage of crop growth, can significantly impact productivity."

ECOSTRESS will hitch a ride to the space station on a NASA-contracted, SpaceX cargo resupply mission scheduled to launch from Cape Canaveral Air Force Station in Florida on June 29. Once it arrives, it will be robotically installed on the exterior of the station's Japanese Experiment Module Exposed Facility Unit.

Over the next year, ECOSTRESS will use the space station's unique low Earth orbit to collect data over multiple areas of land at different times of day. The instrument will produce detailed images of areas as small as 43 by 76 yards (40 by 70 meters) -- about the size of a small farm -- every three to five days.

Other instruments in space can make measurements with the same level of detail or at different times of day -- but not both. ECOSTRESS' dual capability makes it especially important for scientists trying to better understand our natural ecosystems and others working toward improved food security and water resource management.

"As water resources become more critical for our growing population, we need to track precisely how much water our crops need," said ECOSTRESS science lead Josh Fisher of JPL. "We need to know when plants are becoming susceptible to droughts, and we need to know which parts of the ecosystem are more vulnerable because of water stress."

Although not part of its primary mission, ECOSTRESS temperature data will also be valuable for other studies that require temperature information, such as detecting and characterizing volcanoes, wildfires and heat waves.

JPL built and manages the ECOSTRESS mission for NASA's Earth Science Division in the Science Mission Directorate at NASA Headquarters in Washington. ECOSTRESS is sponsored by NASA's Earth System Science Pathfinder program, managed by NASA's Langley Research Center in Hampton, Virginia.

NASA astronaut Drew Feustel is pictured tethered to the International Space Station just outside of the Quest airlock during a spacewalk he conducted with fellow NASA astronaut Ricky Arnold (out of frame) on June 14, 2018.

The Expedition 56 crew's schedule is full of space science today as cleanup continues after last week's spacewalk. The International Space Station's three newest crew members also brushed up on their safety skills.

Спойлер

Biology and physics were just part of the microgravity research taking place aboard the orbital laboratory today. NASA astronaut Serena Auñón-Chancellor started her day collecting blood and urine samples for a trio of ongoing human research studies. She then joined European Space Agency astronaut Alexander Gerst for the Myotone study observing how long-term space missions impact the biochemical properties of muscles. Gerst also researched ways to simplify and speed up procedures for astronauts for the Everywear experiment.

Auñón-Chancellor, Gerst and cosmonaut Sergey Prokopyev also gathered midday to review the location of safety gear throughout the space station. The trio also practiced emergency communication in the station's Russian segment.

NASA astronaut Ricky Arnold spent the day cleaning soot created in a burner during a run of the Advanced Combustion Microgravity Experiment. That study is exploring ways to improve fuel efficiency, reduce pollution and prevent fires in space. Cosmonauts Oleg Artemyev and Prokopyev explored how living in microgravity affects their daily exercise regimen.

Commander Drew Feustel worked in the Quest airlock today continuing cleanup activities after Thursday's six-hour, 49-minute spacewalk. Feustel scrubbed the U.S. spacesuit water loops then tested water samples for conductivity before wrapping up his day.

Navigating Space by the Stars

NASA Johnson

Опубликовано: 19 июн. 2018 г.

A tool that has helped guide sailors across oceans for centuries is now being tested aboard the International Space Station as a potential emergency navigation tool for guiding future spacecraft across the cosmos. The Sextant Navigation investigation tests use of a hand-held sextant aboard the space station.

Sextants have a telescope-like optical sight to take precise angle measurements between pairs of stars from land or sea, enabling navigation without computer assistance. NASA's Gemini missions conducted the first sextant sightings from a spacecraft, and designers built a sextant into Apollo vehicles as a navigation backup in the event the crew lost communications from their spacecraft. Jim Lovell demonstrated on Apollo 8 that sextant navigation could return a space vehicle home. Astronauts conducted additional sextant experiments on Skylab.
