The International Space Station (ISS) serves as a microgravity and space environment research laboratory, where scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is a joint project involving NASA, Roscosmos, JAXA, ESA, and CSA. Regular updates, such as the "Space to Ground" reports, provide insights into the station's activities and research progress. This article summarizes the key events and research activities aboard the ISS during the week leading up to November 3, 2017, based on the available "Space to Ground" report from that period.

Overview of the ISS Weekly Activities (October 27 – November 3, 2017)

During the week of October 27 to November 3, 2017, the ISS crew engaged in a variety of scientific experiments, maintenance tasks, and outreach activities. These efforts aimed to advance our understanding of human health, technology, and the fundamental processes of life in space.

Scientific Research and Experiments

The crew conducted several experiments across different scientific domains:

  • Veggie Plant Growth (VEG-03): The crew harvested leaves from plants cultivated in the Veggie plant growth facility. These samples were preserved for analysis to study how plants respond to microgravity, which is crucial for future long-duration space missions where crew members may need to grow their own food. The Veg-03 investigation focuses on cultivating types of cabbage, lettuce, and mizuna in space. ([nasa.gov](
  • Human Research Program (HRP) Collections: The crew collected blood and urine samples to support the Biochemical Profile and Repository experiments. These samples are analyzed to understand the effects of spaceflight on human physiology, aiding in the development of countermeasures for long-duration missions. ([nasa.gov](
  • Lighting Effects: A crew member provided a sleep log entry and conducted a series of cognition tests. This experiment aims to assess how different lighting conditions affect crew circadian rhythms, sleep patterns, and cognitive performance, which is vital for maintaining crew health and performance during missions.

Maintenance and Operations

Routine maintenance and operational tasks were performed to ensure the ISS's functionality and safety:

  • Cygnus Cargo Operations: The crew completed 12 hours and 45 minutes of cargo operations with the Cygnus spacecraft, achieving 84% of the mission's cargo tasks. Ground specialists estimated that approximately 8 hours were needed to complete the remaining operations. ([nasa.gov](
  • Marrow Investigation: A crew member conducted breath and ambient air sample collections for the Marrow investigation, which examines the effects of microgravity on bone marrow. This research is essential for understanding bone health in space and developing countermeasures for bone loss during long-duration missions. ([nasa.gov](

Outreach and Communication

The ISS crew participated in Earth observation activities to engage the public and provide educational content:

  • Earth Imagery from ISS Target Operations: The crew captured high-resolution images and videos of various Earth locations, including the South Tip of India, the Indian-Himalayas-Tibetan Plateau, the Hawaiian Islands, the Mediterranean Sea at night, and Seattle and the Pacific Northwest US. These visuals are intended for public engagement and educational purposes. ([nasa.gov](

Conclusion

The week leading up to November 3, 2017, aboard the ISS was marked by significant scientific research, maintenance activities, and public outreach efforts. The crew's dedication to these tasks contributes to the advancement of space science and the preparation for future human exploration missions. Regular updates like the "Space to Ground" reports are vital for keeping the public informed about the ongoing activities and achievements of the ISS program.
