Preparations for Next Moonwalk Simulations Underway (and Underwater)

Science in Space: August 2024

Life on the International Space Station is quite different from life on the ground. Crew members experience multiple sunrises and sunsets each day, spend their time in a confined space, have packed schedules, and deal with microgravity.

These and other conditions during spaceflight can negatively affect the performance and well-being of crew members. Many studies on the space station work to characterize and understand those effects and others try out new technologies and practices to help counter them.

Light Up My Life

A current investigation from ESA (European Space Agency), Circadian Light tests a new lighting system to help astronauts maintain a more normal daily or circadian rhythm. An LED panel automatically and gradually changes the light spectrum and varies from day to day to better mimic natural conditions on Earth. The study seeks insight into this system’s effect on circadian rhythm regulation, sleep, stress, and overall well-being of crew members. The findings also could reveal ways to improve lighting for shift workers and those in extreme or remote environments.

Daily Rhythms

An earlier ESA investigation, Circadian Rhythms, examined how daily rhythms change during long-duration spaceflight and its non-24-hour cycles of light and dark. This understanding could support countermeasures to improve performance and health on future missions.

A well-established way to determine circadian rhythms is by continuously recording core body temperature, but methods to do so can be invasive and inconvenient. For this investigation, researchers developed non-invasive skin sensor technology for measuring body core temperature over extended periods of time.

Astronaut, Phone Home

Missions to the Moon or Mars will experience delays in communications with Earth – as much as 30 minutes each way from Mars. The Comm Delay Assessment investigation looked at how such delays might affect crew members handling medical and other emergencies to help psychologists develop ways to manage the stress of completing these critical tasks without immediate advice from Earth. Results showed that the space station could provide a platform to test communications delay countermeasures. The research also confirmed that communication delays increased individual stress and frustration and reduced task efficiency and teamwork, and suggested that enhanced training, teamwork, and technology could mitigate or prevent these problems.

This is Your Brain in Space

NeuroMapping studied changes to brain structure and function, motor control, and multi-tasking abilities during spaceflight and measured how long it took crew members to recover after a mission. Results published from this work include a study that found no effect on spatial working memory from spaceflight but that did identify significant changes in brain connectivity. Another paper reported substantial increases in brain volume that increased with mission duration and with longer intervals between missions. The researchers suggest that intervals of less than 3 years between missions may not be sufficient for full recovery.

Dear Diary

For the Journals investigation, crew members wrote daily entries that researchers analyzed to identify issues related to well-being. The study provided the first quantitative data for ranking the behavioral issues associated with spending lengthy time in space. Most journal entries dealt with ten categories: work, outside communications, adjustment, group interaction, recreation/leisure, equipment, events, organization/management, sleep, and food. The report provided insight into how these factors affect human performance and included recommendations to help crews prepare for spaceflight and to improve living and working in space.

Don’t Throw Away This Shot

Crew members on the space station take photographs of their home planet for Crew Earth Observations (CEO). These images record how humans and natural events change Earth over time and support a wealth of research on the ground, including studies of urban growth, natural systems such as coral reefs and icebergs, land use, and ocean events. Over time, researchers realized that taking these photographs also improves the mental well-being of crew members. Many of them spend much of their free time shooting from the station’s cupola.

Almost like Being There

ESA’s VR Mental Care tests the use of virtual reality (VR) technology to provide mental relaxation and better general mental health for astronauts during their missions. Participating crew members use a headset to view 360-degree, high-quality video and sound scenarios and fill out questionnaires about the experience. In addition to helping astronauts, this tool could be used to deal with psychological issues such as stress, anxiety, and post-traumatic stress disorder on Earth.

      From left to right, NASA’s Carruthers Geocorona Observatory, IMAP (Interstellar Mapping and Acceleration Probe), and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On-Lagrange 1 (SWFO-L1) missions will map our Sun’s influence across the solar system in new ways. Credit: NASA NASA will provide live coverage of prelaunch and launch activities for an observatory designed to study space weather and explore and map the boundaries of our solar neighborhood.
      Launching with IMAP (Interstellar Mapping and Acceleration Probe) are two rideshare missions, NASA’s Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On-Lagrange 1 (SWFO-L1), both of which will provide insight into space weather and its impacts at Earth and across the solar system.
      Liftoff of the missions on a SpaceX Falcon 9 rocket is targeted for 7:32 a.m. EDT, Tuesday, Sept. 23, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Watch coverage beginning at 6:40 a.m. on NASA+, Amazon Prime, and more. Learn how to watch NASA content through a variety of platforms, including social media.
      The IMAP spacecraft will study how the Sun’s energy and particles interact with the heliosphere — an enormous protective bubble of space around our solar system — to enhance our understanding of space weather, cosmic radiation, and their impacts on Earth and human and robotic space explorers. The spacecraft and its two rideshares will orbit approximately one million miles from Earth, positioned toward the Sun at a location known as Lagrange Point 1.
      NASA’s Carruthers Geocorona Observatory is a small satellite that will observe Earth’s outermost atmospheric layer, the exosphere. It will image the faint glow of ultraviolet light from this region, called the geocorona, to better understand how space weather impacts our planet. The Carruthers mission continues the legacy of the Apollo era, expanding on measurements first taken during Apollo 16.
      The SWFO-L1 spacecraft will monitor space weather and detect solar storms in advance, serving as an early warning beacon for potentially disruptive space weather, helping safeguard Earth’s critical infrastructure and technological-dependent industries. The SWFO-L1 spacecraft is the first NOAA observatory designed specifically for and fully dedicated to continuous, operational space weather observations.

      Image: Group photo taken at the General Assembly on Defence, Space and Cybersecurity, held on Friday 12 September 2025, at ESRIN, ESA’s Centre for Earth Observation Programmes in Italy. 
      The event was organised by the European Parliament and the European Commission, in collaboration with the European Space Agency, to promote dialogue between European and national decision-makers and industry leaders. Representatives from major European entities debated the future of the European Union, which is facing unprecedented challenges since the postwar period, in an increasingly complex geopolitical context. Participants examined Europe’s needs in key sectors such as space, cybersecurity, and defence, within the broader context of the Atlantic Alliance. Acting at the European level, as demonstrated by projects like Galileo, EGNOS, and Copernicus, not only brings extraordinary added value in terms of innovation, industrial competitiveness, economies of scale, and spending efficiency, but also strengthens Europe’s strategic autonomy, the security of its citizens, and the protection of its critical infrastructure.
      The group included experts from major European entities, including: Andrius Kubilius, European Commissioner for Defence and Space; Adolfo Urso, Italian Minister of Enterprises and Made in Italy; Matteo Piantedosi, Italian Minister of the Interior; Gen. B. Luigi Vinciguerra, Brigade General of the Guardia di Finanza – Head of the III Operations Department, General Command; Josef Aschbacher, Director General of the European Space Agency; Simonetta Cheli, Director of Earth Observation Programmes and Head of ESRIN; Carlo Corazza, Head of the European Parliament Office in Italy; Ammiraglio Giuseppe Cavo Dragone, Chairman of the NATO Military Committee; Teodoro Valente, President of the Italian Space Agency (ASI); Hans de Vries, Chief Cybersecurity and Operations Officer (COO) - ENISA; Fabio di Stefano, Communications at the European Parliament in Italy.
