NASA’s SpaceX Crew-10 Mission: A Journey of Scientific Discovery
In early August, NASA’s SpaceX Crew-10 mission is scheduled to return to Earth, concluding an extended stay aboard the International Space Station (ISS). This mission features a diverse team of astronauts: NASA’s Anne McClain and Nichole Ayers, JAXA’s Takuya Onishi, and Roscosmos’ Kirill Peskov. During their tenure in space, these astronauts have contributed significantly to scientific research, pushing the boundaries of our understanding of space and its effects on various biological and technological processes.
Scientific Milestones of Crew-10
The Crew-10 mission has been a hotbed of scientific activity, leading to numerous breakthroughs and advancements. Let’s delve into some key scientific achievements accomplished during this mission:
1. Rhodium Plant LIFE Experiment
A unique experiment conducted during this mission involved wild-type and genetically-modified thale cress plants. These plants were part of the Rhodium Plant LIFE experiment, which aimed to understand how different orbital environments affect plant growth, especially in terms of radiation and gravity. By comparing data from Crew-10 with that from the Polaris Dawn mission, which ventured deeper into space, scientists sought to unravel the mysteries of how microgravity influences plant growth rates. This research is crucial for developing better plant cultivation techniques both in space and on Earth.
2. International Space Station Roll-Out Solar Array (IROSA)
Anne McClain participated in a spacewalk to upgrade the ISS’s power systems. This involved installing hardware to support the International Space Station Roll-Out Solar Array (IROSA). These new solar arrays are more compact and efficient than the original ones, thus enhancing the power available for scientific research and other activities. Initially demonstrated in June 2017, IROSA technology has now become integral to the ISS’s energy infrastructure.
3. SOPHONSTER Study
Nichole Ayers utilized the ISS’s Space Automated Bioproduct Laboratory to process samples for the SOPHONSTER study. This research focuses on how microgravity affects the protein yield of microalgae, which are rich in essential nutrients like amino acids, fatty acids, and vitamins. The findings could provide sustainable meat and dairy alternatives for long-duration space missions and even lead to the development of biofuels and medicines both in space and on Earth.
4. Studying Lightning from Space
Ayers captured a stunning image of simultaneous lightning strikes over two thunderstorms while the ISS orbited more than 250 miles above Earth. Such observations, made possible by instruments on the space station, help scientists better understand weather conditions in Earth’s upper atmosphere. This research aids in protecting communication systems, aircraft, and improves atmospheric models and weather predictions.
5. APEX-12 Investigation
In collaboration with Ayers, Takuya Onishi harvested samples for the APEX-12 investigation. This study examines the effects of space radiation on telomere activity in thale cress plants. Telomeres are DNA sequences that protect chromosome ends and are indicators of cell aging. Understanding their role in aging and disease could help scientists prepare plants and organisms for the stresses of prolonged space travel.
6. ELVIS Microscope
A fluorescent microscope known as ELVIS was employed to capture 3D movements of microscopic algae and bacteria. This new capability aboard the ISS could prove invaluable in applications such as monitoring water quality and detecting infectious organisms. Anne McClain prepared bacterial samples for viewing with this advanced microscope, showcasing its potential for space and Earth-based research.
7. Cell Gravisensing Investigation
The Cell Gravisensing investigation sought to uncover how cells sense gravity, a mechanism that remains largely unknown. Conducted by Onishi in the ISS’s Kibo laboratory, this research could lead to therapies for muscle and bone conditions, including muscle atrophy during spaceflight and osteoporosis on Earth.
8. Exploration Potable Water Dispenser
Ayers and McClain worked on installing hardware for the ISS’s Exploration Potable Water Dispenser. This device’s ability to sanitize water and reduce microbial growth is being evaluated, with implications for future exploration missions. It provides room temperature and hot water for crew consumption and food preparation.
9. JEM Internal Ball Camera 2
Onishi monitored the JEM Internal Ball Camera 2, a free-flying, rechargeable camera that offers a unique visual perspective aboard the ISS. Its ability to capture video and imagery of scientific experiments could free up crew time for other research activities.
10. Ring Sheared Drop-IBP-2 Experiment
Ayers set up the Ring Sheared Drop device, which uses surface tension to study liquid proteins in microgravity. This method eliminates interactions between solutions and container walls, potentially advancing manufacturing processes in space and Earth, particularly for next-generation medicines to treat diseases like cancer.
11. Advanced Space Experiment Processor-4
McClain swapped out hardware in the ISS’s Advanced Space Experiment Processor-4, facilitating physical science and crystallization research. This technology could improve pharmaceutical manufacturing on Earth and enable medication production during deep space missions.
12. Continuous Health Monitoring
McClain assisted Onishi in collecting blood samples, part of NASA’s continuous health monitoring of astronauts. Analyzing these samples helps track cardiovascular and immune system functions, bone and muscle mass changes, nutritional status, and mental well-being. Such studies are vital for understanding how the human body adapts to weightlessness.
13. Studying the Sun’s Corona
An animated, color-coded heat map showcased temperature changes in the Sun’s outer atmosphere or corona, collected during the Crew-10 mission. Using a coronagraph, this investigation helps scientists understand the solar wind’s energy source, which constantly bombards Earth.
14. Industrial Crystallization Cassette
Onishi serviced the ISS’s Advanced Space Experiment Processor-4 for the ADSEP-Industrial Crystallization Cassette investigation. This research tests new hardware that could enable in-space production of pharmaceuticals, benefiting commercial space applications.
15. Nanoracks Module-9 Swiss Chard Experiment
Ayers prepared mixture tubes for the Swiss Chard experiment, a student-designed study examining how space-grown Swiss chard differs from Earth-grown counterparts. This ongoing plant research on the ISS provides insights into food sources and benefits for future long-duration missions.
16. Eye Health Monitoring
Onishi, with Ayers’ assistance, conducted eye exams using optical coherence tomography, a technology that produces 3D images of the retina and other eye structures. This monitoring helps understand how spaceflight affects eye health and vision.
The Crew-10 mission has been a remarkable chapter in space exploration, showcasing the potential of international collaboration and cutting-edge research aboard the ISS. As the crew prepares to return to Earth, they leave behind a legacy of scientific achievements that will continue to benefit humanity both in space and on our home planet.
