Modeling properties of thunderstorm discharges
Researchers report detailed physical properties of different types of corona discharges, including single- and multi-pulse blue discharges linked to powerful but short-lived electrical bursts near the tops of clouds. These details provide a reference for further investigation into the physical mechanisms behind these discharges and their role in the initiation of lightning, an important problem in lightning physics.
An ESA (European Space Agency) instrument used to study thunderstorms, Atmosphere-Space Interactions Monitor (ASIM) provides insights into their role in Earth’s atmosphere and climate, including mechanisms behind the creation of lightning. Understanding how thunderstorms and lightning disturb the upper atmosphere could improve atmospheric models along with climate and weather predictions. These high-altitude discharges also affect aircraft and spacecraft safety.

Researchers conclude that the space station’s ECOSTRESS instrument yields highly accurate sea surface temperature data. Given the instrument’s global coverage and high spatial resolution, these data have potential use in studies of biological and physical oceanography to evaluate regional and local effects of climate change.
ECOSTRESS resolves oceanographic features not detectable in imagery from NOAA’s Visible Infrared Imaging Radiometer Suite satellite, and has open-ocean coverage, unlike Landsat. Satellites are a fundamental tool to measure sea surface temperatures, which are rising across all oceans due to atmospheric warming induced by climate change.

Researchers report detailed observations and analysis of emissions from an exceptionally bright gamma ray burst (GRB), 210619B, detected by the station’s ASIM and other satellite and ground-based instruments. These observations could be useful in determining various properties of GRBs and how they change during different phases.
Believed to be generated by the collapse of massive stars, GRBs are the brightest, most explosive transient electromagnetic events in the universe. ASIM can observe thunderstorm discharges difficult to observe from the ground. It has a mode where a detected event triggers observation and onboard storage of data.

Measuring water loss from space
This study showed that the International Space Station’s ECOSTRESS instrument estimates of evapotranspiration (transfer of water to the atmosphere from Earth’s surface and plants) are comparable to ground-based reference values. This finding suggests space measurements could provide guidance for improved water management on large scales.
Worsening droughts due to climate change require better water management. Evapotranspiration is a critical part of the hydrologic cycle, but data are lacking on local water conditions and demands. California’s Eastern Municipal Water District uses the ground-based California Irrigation Management Information System to track evapotranspiration, but it has limited spatial coverage and consistency. Space-based estimates could be better and more consistent.

Four-legged robotic retrievers
Space station crew members successfully located and retrieved an object in a simulated Mars environment using a remotely controlled four-legged robot, Bert. Legged robots could provide the ability to explore and survey different extraterrestrial surfaces on future missions.
On uneven lunar and planetary surfaces, robots with legs could explore areas inaccessible to wheeled rovers. Surface Avatar, an investigation from ESA (European Space Agency), evaluated remote control of multiple robots in space, providing information on how human operators respond to physical feedback (such as feeling a bump when a robot arm makes contact) and identifying challenges for orbit-to-ground remote operation of robots. The German Aerospace Center is developing Bert.

Technology supports atmospheric studies
Researchers found that the Compact Thermal Imager (CTI) on the space station produced scientifically useful imagery of atmospheric phenomena, including gravity waves, clouds, and volcanic plumes. This technology could change current practices and instrument design for remote sensing of Earth from space.
The CTI is mounted on hardware for Robotic Refueling Mission 3, which tested technology for the robotic transfer and storage of cryogenic fluids in microgravity. The station’s orbit provides near-global coverage and CTI has reduced size, energy use, and cost. Its images can measure fires, ice sheets, glaciers, and snow surface temperatures on the ground and the transfer of water from soil and plants into the atmosphere.

Seeds survive space
A close-up view of the Materials International Space Station Experiment hardware housing materials for exposure to space.NASA Researchers found that plant seeds exposed to space germinated at the same rate as those kept on the ground. This finding shows that plant seeds can remain viable during long-term space travel and plants could be used for food and other uses on future missions.
Materials International Space Station Experiment-14 exposed a variety of materials to space, including 11 types of plant seeds. The work also evaluated the performance of a new sample containment canister as a method of exposing biological samples to space while protecting their vigor.
Examining mechanisms of immune issues in space
NASA astronaut Josh Cassada stows samples from blood collection activities inside an International Space Station science freezer.NASA Using genetic analyses, researchers identified molecular mechanisms that cause changes in mitochondrial and immune system function seen during spaceflight. The findings provide insight into how the human body adapts in space and could guide countermeasures for protecting immune function on future missions.
International Space Station Medical Monitoring collects a variety of health data from crew members before, after, and at regular intervals during spaceflight. Evaluations fall into broad categories of medical, occupational, physical fitness, nutrition, and psychological or behavioral and include blood tests. Mitochondria are cell organelles that produce energy.
Reducing vision changes in space

Researchers found that artificial gravity may reduce these changes and could serve as a countermeasure to protect the vision of crew members on future missions.
Previous studies provide evidence that artificial gravity may protect against or mitigate negative effects of microgravity. An investigation from JAXA (Japan Aerospace Exploration Agency) in collaboration with NASA’s Human Research and Space Biology Programs, Mouse Habitat Unit-8 looked at the long-term effects of spaceflight on gene expression patterns in mammals. More research is needed to identify the effects of other spaceflight stressors and determine what level and duration of gravitational force is needed to prevent or reduce damage to the retina or optic nerve.
