Researchers used an interferometer that can precisely measure gravity, magnetic fields, and other forces to study the influence of International Space Station vibrations. Results revealed that matter-wave interference of rubidium gases is robust and repeatable over a period spanning months. Atom interferometry experiments could help create high-precision measurement capabilities for gravitational, Earth, and planetary sciences. Using ultracold rubidium atoms, Cold Atom Lab researchers examined a three-pulse Mach–Zehnder interferometer, a device that determines phase shift variations between two parallel beams, to understand the influence of space station vibrations. Researchers note that atom sensitivities and visibility degrade…

The uncrewed spacecraft will depart from the orbiting laboratory for a landing at White Sands Space Harbor in New Mexico. Starliner is scheduled to autonomously undock from the space station at approximately 6:04 p.m. EDT Friday, Sept. 6, to begin the journey home, weather conditions permitting. NASA and Boeing…

Researchers successfully produced cellulose from bacteria cultured on the International Space Station for four weeks. The bacteria used in the experiment, K. hansenii, is known to produce the highest amount of cellulose and could be considered for large-scale production in microgravity to support the development of materials used in construction, clothing, and the supply of energy. Ice Cubes Experiment Cube #4, #5- Kirara, a temperature-controlled module typically used for protein crystallization, was used here to incubate the target bacteria. Researchers developed a customized methodology that consisted of adjusting gas and…

NASA Shares Asteroid Bennu Sample in Exchange with JAXA

NeRD

As part of an asteroid sample exchange, NASA has transferred to JAXA (Japan Aerospace Exploration Agency) a portion of the asteroid Bennu sample collected by the agency’s OSIRIS-REx mission. The sample was officially handed over by NASA officials during a ceremony on Aug. 22 at JAXA’s Sagamihara, Japan, campus. The signature exchange for the Bennu sample transfer took place on Aug. 22, 2024, at JAXA’s (Japan Aerospace Exploration Agency) Institute of Space and Astronautical Science, Sagamihara Campus. JAXA This asteroid sample transfer follows the November 2021 exchange where JAXA transferred…

Locations designed as a maintenance work area and an exercise area on the International Space Station are commonly used by crew members for stowage and body maintenance activities, respectively. These differences between intended and actual use demonstrate that systematic observation of material culture can help researchers identify how astronauts adapt to life in microgravity and support better design of future spacecraft and habitats. The first archaeological fieldwork in space, SQuARE examined the space station’s material culture – objects and built spaces and their symbolic and social meanings – and how these objects and spaces…

Mission managers continue to evaluate the Starliner spacecraft’s readiness in advance of decisional meetings no earlier than next week regarding the return of NASA astronauts Butch Wilmore and Suni Williams. Audio of the teleconference…

Researchers tested a treatment on cartilage and bone tissue cultures subjected to compressive impact injury and found differences in the metabolites and proteins released by cells in space and on Earth along with partial improvement in both gravity conditions. The findings suggest the treatment is safe and could help ensure the health of crew members on future missions and patients on Earth. Astronauts have high rates of musculoskeletal injuries, and post-traumatic osteoarthritis from joint injuries is a major contributor to disability across all ages on the ground. MVP Cell-06 used cultures of human knee…

Analyses suggest that microgravity does not significantly alter fundamental biochemical pathways in kidney cells, including metabolism of vitamin D. This finding could help researchers develop strategies to protect crew health on future missions and improve treatment of kidney-related diseases on Earth.  Kidney Cells examined the effects of microgravity and other factors of space travel on kidney health. Previous reports suggested that changes in kidney cell metabolism of vitamin D plays a role in bone loss in microgravity, and this paper recommends additional study to determine if this most recent finding is consistent with extended (>6…
