Engineered heart tissues in space showed impairments that led to increased arrhythmias and loss of muscle strength, changes similar to cardiac aging. This finding suggests that the engineered tissues, essentially an automated heart-on-a-chip platform, can be used to study cardiac issues in space and aging-related cardiovascular disease on Earth. Microgravity exposure is known to cause changes in cardiovascular function similar to those seen with aging on Earth. Engineered Heart Tissues assessed these changes using 3D cultured cardiac muscle tissue. The 3D cultures, grown with special scaffolds and derived from human cells, are better at…

NASA Invites Media to SpaceX’s 31st Resupply Launch to Space Station

NeRD

The SpaceX Dragon spacecraft approaching the International Space Station Credits: NASA Media accreditation is open for the next launch to deliver NASA science investigations, supplies, and equipment to the International Space Station. This launch is the 31st SpaceX commercial resupply services mission to the orbital laboratory for the agency and will lift off on the company’s Falcon 9 rocket. NASA and SpaceX are targeting no earlier than Wednesday, Oct. 30, to launch the SpaceX Dragon spacecraft from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Credentialing to cover…

Facility Managers, Assemble: Protecting Johnson Space Center’s People and Places

NeRD

Not all heroes wear capes (or blue flight suits). At Johnson Space Center in Houston, the heroes might train their colleagues how to safely respond and evacuate their office in an emergency. They might investigate office accidents and remove potential hazards. Or they might help fix a leaky bathroom sink or a broken coffee maker. Those heroes are approximately 135 on-site facility managers who ensure the safety and health of every building and its occupants. Established in 2009, the Facility Manager program encompasses buildings at Johnson Space Center, Sonny Carter…

Researchers found that long-duration spaceflight affected the mechanical properties of eye tissues, including reducing the stiffness of tissue around the eyeball. A better understanding of these changes could help researchers prevent, diagnose, and treat the vision impairment often seen in crew members. SANSORI, a Canadian Space Agency investigation, examined whether reduced stiffness of eye tissue contributes to vision impairment in astronauts on long-term missions. This condition, known as Spaceflight Associated Neuro-Ocular Syndrome, or SANS, includes a range of physical changes to the eyes. This paper suggests that biomechanical changes in the eye…

Researchers found that eddies, or swirling wind patterns, increased moisture evaporation in an alfalfa field. A better understanding of the complex exchange of water and heat between the ground and atmosphere could improve remote sensing products and their use in agricultural water management.   The station’s ECOSTRESS instrument takes high-resolution thermal infrared measurements of Earth’s surface that provide data on changes in water availability, vegetation water stress, and agricultural water use. Researchers use observations from the USGS Landsat 8 and 9 satellites and ECOSTRESS to validate climate models and update data…
