Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA and SpaceX are launching the company’s 32nd commercial resupply services mission to the International Space Station later this month, bringing a host of new research to the orbiting laboratory. Aboard the SpaceX Dragon spacecraft are experiments focused on vision-based navigation, spacecraft air quality, materials for drug and product manufacturing, and advancing plant growth with less reliance on photosynthesis.
This and other research conducted aboard the space station advances future space exploration, including missions to the Moon and Mars, and provides many benefits to humanity.
Investigations traveling to the space station include:
Robotic spacecraft guidance
Smartphone Video Guidance Sensor-2 (SVGS-2) uses the space station’s Astrobee robots to demonstrate using a vision-based sensor developed by NASA to control a formation flight of small satellites. Based on a previous in-space demonstration of the technology, this investigation is designed to refine the maneuvers of multiple robots and integrate the information with spacecraft systems.
Potential benefits of this technology include improved accuracy and reliability of systems for guidance, navigation, and control that could be applied to docking crewed spacecraft in orbit and remotely operating multiple robots on the lunar or Martian surface.

During spaceflight, especially long-duration missions, concentrations of airborne particles must be kept within ranges safe for crew health and hardware performance. The Aerosol Monitors investigation tests three different air quality monitors in space to determine which is best suited to protect crew health and ensure mission success. The investigation also tests a device for distinguishing between smoke and dust. Aboard the space station, the presence of dust can cause false smoke alarms that require crew member response. Reducing false alarms could save valuable crew time while continuing to protect astronaut safety.
Better materials, better drugs
The DNA Nano Therapeutics-Mission 2 produces a special type of molecule formed by DNA-inspired, customizable building blocks known as Janus base nanomaterials. It also evaluates how well the materials reduce joint inflammation and whether they can help regenerate cartilage lost due to arthritis. These materials are less toxic, more stable, and more compatible with living tissues than current drug delivery technologies.
Environmental influences such as gravity can affect the quality of these materials and delivery systems. In microgravity, they are larger and have greater uniformity and structural integrity. This investigation could help identify the best formulations and methods for cost-effective in-space production. These nanomaterials also could be used to create novel systems targeting therapy delivery that improves patient outcomes with fewer side effects.

The newest Industrial Crystallization Cassette (ADSEP-ICC) investigation adds capabilities to an existing protein crystallization facility. The cassette can process more sample types, including tiny gold particles used in devices that detect cancer and other diseases or in targeted drug delivery systems. Microgravity makes it possible to produce larger and more uniform gold particles, which improves their use in research and real-life applications of technologies related to human health.
Helping plants grow
Rhodium USAFA NIGHT examines how tomato plants respond to microgravity and whether a carbon dioxide replacement can reduce how much space-grown plants depend on photosynthesis. Because photosynthesis needs light, which requires spacecraft power to generate, alternatives would reduce energy use. The investigation also examines whether using supplements increases plant growth on the space station, which has been observed in preflight testing on Earth. In future plant production facilities aboard spacecraft or on celestial bodies, supplements could come from available organic materials such as waste.
Understanding how plants adapt to microgravity could help grow food during long-duration space missions or harsh environments on Earth.

An ESA (European Space Agency) investigation, Atomic Clock Ensemble in Space (ACES), examines fundamental physics concepts such as Einstein’s theory of relativity using two next-generation atomic clocks operated in microgravity. Results have applications to scientific measurement studies, the search for dark matter, and fundamental physics research that relies on highly accurate atomic clocks in space. The experiment also tests a technology for synchronizing clocks worldwide using global navigation satellite networks.

Sromovsky An international team of astronomers using the NASA/ESA Hubble Space Telescope has made new measurements of Uranus’ interior rotation rate with a novel technique, achieving a level of accuracy 1,000 times greater than previous estimates. By analyzing more than a decade of Hubble observations of Uranus’ aurorae, researchers have refined the planet’s rotation period and established a crucial new reference point for future planetary research.
These images from the NASA/ESA Hubble Space Telescope showcase the dynamic aurora on Uranus in October 2022. These observations were made by the Space Telescope Imaging Spectrograph (STIS) and includes both visible and ultraviolet data. An international team of astronomers used Hubble to make new measurements of Uranus’ interior rotation rate by analyzing more than a decade of the telescope’s observations of Uranus’ aurorae. This refinement of the planet’s rotation period achieved a level of accuracy 1000 times greater than previous estimates and serves as a crucial new reference point for future planetary research. ESA/Hubble, NASA, L. Lamy, L. Sromovsky Determining a planet’s interior rotation rate is challenging, particularly for a world like Uranus, where direct measurements are not possible. A team led by Laurent Lamy (of LIRA, Observatoire de Paris-PSL and LAM, Aix-Marseille Univ., France), developed an innovative method to track the rotational motion of Uranus’ aurorae: spectacular light displays generated in the upper atmosphere by the influx of energetic particles near the planet’s magnetic poles. This technique revealed that Uranus completes a full rotation in 17 hours, 14 minutes, and 52 seconds — 28 seconds longer than the estimate obtained by NASA’s Voyager 2 during its 1986 flyby.
“Our measurement not only provides an essential reference for the planetary science community but also resolves a long-standing issue: previous coordinate systems based on outdated rotation periods quickly became inaccurate, making it impossible to track Uranus’ magnetic poles over time,” explains Lamy. “With this new longitude system, we can now compare auroral observations spanning nearly 40 years and even plan for the upcoming Uranus mission.”
This image of Uranus’ aurorae was taken by the NASA/ESA Hubble Space Telescope on 10 October 2022. These observations were made by the Space Telescope Imaging Spectrograph (STIS) and includes both visible and ultraviolet data. An international team of astronomers used Hubble to make new measurements of Uranus’ interior rotation rate by analyzing more than a decade of the telescope’s observations of Uranus’ aurorae. This refinement of the planet’s rotation period achieved a level of accuracy 1000 times greater than previous estimates and serves as a crucial new reference point for future planetary research. ESA/Hubble, NASA, L. Lamy, L. Sromovsky This breakthrough was possible thanks to Hubble’s long-term monitoring of Uranus. Over more than a decade, Hubble has regularly observed its ultraviolet auroral emissions, enabling researchers to produce magnetic field models that successfully match the changing position of the magnetic poles with time.
“The continuous observations from Hubble were crucial,” says Lamy. “Without this wealth of data, it would have been impossible to detect the periodic signal with the level of accuracy we achieved.”
Unlike the aurorae of Earth, Jupiter, or Saturn, Uranus’ aurorae behave in a unique and unpredictable manner. This is due to the planet’s highly tilted magnetic field, which is significantly offset from its rotational axis. The findings not only help astronomers understand Uranus’ magnetosphere but also provide vital information for future missions.
These findings set the stage for further studies that will deepen our understanding of one of the most mysterious planets in the Solar System. With its ability to monitor celestial bodies over decades, the Hubble Space Telescope continues to be an indispensable tool for planetary science, paving the way for the next era of exploration at Uranus.
These results are based on observations acquired with Hubble programs GO #12601, 13012, 14036, 16313 and DDT #15380 (PI: L. Lamy). The team’s paper was published in Nature Astronomy.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.
