NASA experiments focused on human and plant health and drug-resistant organisms will travel to the International Space Station aboard SpaceX’s 35th Commercial Resupply Services mission for the agency from Cape Canaveral Space Force Station in Florida, advancing research that benefits life on Earth and future exploration.
This research supports astronaut health during long-duration missions through four investigations from the agency’s Biological and Physical Sciences division, including 3D models of the human brain, a crop disease study, a faster way to assess astronaut health, and an analysis of antibiotic-resistant bacteria aboard the space station.
Tiny brain models, big questions
A new precision health investigation helps address a key question: What happens to the human brain in space?
The experiment sends small, lab-grown models of the human brain to the orbiting laboratory for five weeks. Researchers compare tissue models that traveled to space with identical ones kept on Earth to determine how a short spaceflight affects the human brain at the cellular level.
The effort could deepen our understanding of how the human brain responds to stress and help lay the groundwork for methods that counter risks to brain health that astronauts may face on future missions to the Moon and beyond.
Disease-resistant crops for space
A space crops investigation tests whether crop diseases develop faster and more severely in microgravity.
The experiment compares molecular and structural changes between Earth-grown and space station-grown plants infected with a disease-causing fungus. The findings could guide plant breeding on Earth to produce disease-resistant crops and help minimize yield losses in future space agriculture systems.
Space crops provide nutrition, increase dietary variety, and offer psychological benefits for astronauts during extended missions. They also absorb carbon dioxide, produce oxygen, and recycle water, which will become increasingly important as human missions extend farther from Earth.
Analysis helps astronauts thrive
The spacecraft also carries the first test of a compact microplate reader that arrived aboard the space station earlier this year.
The Commercially Enabled Rapid Space Science initiative experiment tests the device’s ability to detect and measure certain biomarkers such as antibodies, antigens, and proteins.
Use of the plate reader would allow scientists to analyze samples aboard the space station and obtain data quickly, rather than wait for the samples to return to Earth for analysis.
Ultimately, the research aims to support the timely detection of infections and other health issues in astronauts while expanding science capabilities in remote exploration locations where resupply will be more difficult.
Tracking antibiotic-resistant bacteria
A precision health investigation returns for its fourth and final planned stay aboard the space station to study how antibiotic-resistant bacteria survive and evolve in microgravity.
As part of the investigation, astronauts repeatedly sample surfaces throughout the space station to monitor for drug-resistant organisms.
The work could help develop ways to protect astronauts against bacterial infections during long-duration missions. On Earth, the findings could provide insight into how superbugs develop from the overuse of antibiotics.

Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: How many moons can you see? The best answer is five: four orbiting Jupiter and Luna orbiting Earth. This multi-moon picture was possible because Earth’s Moon moved directly in front of Jupiter last week. The featured image is a series of exposures near alignment taken from Westchester, New York, USA. The sunlit crescent of Earth’s Moon, on the lower left, is overexposed, while the Moon’s night side, on the upper right, is faintly illuminated by Earthshine. Lined up nearly vertically above our Moon, listed from bottom to top, are Jupiter’s bright Galilean satellites: Ganymede, Io, Callisto, and Europa. Callisto, Ganymede, and Io are larger than Earth’s Moon, while Europa is only slightly smaller. NASA’s robotic spacecraft Juno is currently orbiting Jupiter and has made close passes near three of these moons.

This story is an update to the Antarctic sea ice feature in our World of Change series tracking long-term change on Earth’s surface through satellite imagery.
Unlike the Arctic—an ocean basin surrounded by land—the Antarctic is a large continent surrounded by an ocean. Because of this geography, sea ice has more room to expand during the winter. However, that ice also stretches into warmer latitudes, leading to more melting in the summer. Antarctic sea ice usually peaks in September, around the end of the Southern Hemisphere’s winter, and retreats to a minimum in February.
According to NASA and the National Snow and Ice Data Center (NSIDC), Antarctic sea ice in 2026 likely reached its annual maximum extent on September 14 (above). On that date, the ice covered an estimated 17.59 million square kilometers (6.79 million square miles), making it the third-lowest maximum on record.
The maps below show the average concentration of Antarctic sea ice for the month of September (left) and the following February (right) from 1990 to 2026. Opaque white areas indicate the highest concentrations, and dark blue areas are open water. The images include only areas where ice concentration was at least 15 percent, a threshold scientists commonly use to count an area as ice-covered in satellite data. Scientists refer to the total area of these regions as the “sea ice extent.”
From 1979 until 2014, total Antarctic sea ice increased by about 1 percent per decade. Whether the increase was a sign of meaningful change is uncertain because ice extents vary considerably from year to year around Antarctica. For three consecutive years, from 2012 to 2014, satellites observed new record highs for winter sea ice extent. These highs occurred while Arctic ice was in steep decline.
The climb came to an end in 2015, and significant decreases in sea ice around Antarctica started to occur in 2016. There have since been years with small rebounds, but overall, Antarctic sea ice coverage has largely remained lower than normal. Both the record low minimum and record low maximum occurred in 2023. Scientists will continue to observe the area each year to find out if the decline is part of a long-term change or a statistical fluctuation.
To determine sea ice extent, scientists rely on satellites with passive microwave sensors that measure the microwave energy Earth naturally emits. Sea ice emits more of this energy than open water, so it stands out in microwave images. Because microwaves pass through clouds, the satellites can observe sea ice regularly, regardless of weather.
The record began in late 1978 with data collected by NASA’s Nimbus-7, followed by Defense Meteorological Satellite Program (DMSP) satellites starting in 1987, and by NASA’s Aqua satellite between 2002 and 2011. In 2025, scientists began using observations from the Japan Aerospace Exploration Agency’s GCOM-W satellite.

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: Scientists are melting holes in the bottom of the world. In fact, almost 100 holes melted near the South Pole are now being used as an astronomical observatory. Astronomers with the IceCube Neutrino Observatory lowered a long string knotted with basketball-sized light detectors into each vertical lake. The water in each hole soon refreezes. The detectors attached to the strings are sensitive to blue light emitted in the surrounding clear ice. Such light results from fast-moving secondary particles liberated when high-energy neutrinos emitted by powerful processes out in the universe collide with ice molecules. IceCube has now detected many illuminating neutrinos. Pictured in 2010, one of the last of IceCube’s detector strings is lowered into the freezing abyss, making IceCube the largest neutrino detector ever created. In recognition of unprecedented discoveries, it was announced earlier this week that a founding leader of the IceCube Collaboration will be awarded the Nobel Prize in Physics.
