Polaris Dawn project aims to prevent bone loss in space
Wednesday, 11 September 2024 16:27
Dartmouth researchers have a project aboard the Polaris Dawn mission they hope will help address two major health risks of space flight—the breakdown of astronauts' bones in zero-gravity conditions and the resulting danger of developing kidney stones.
When subjected to weightlessness, bones freed from the burden of supporting the human body leach calcium. The shedding of this critical element reduces bone density and, as the calcium enters the urine, heightens the chance of painful kidney stones forming in the urinary tract.
Through Polaris Dawn, which launched from Florida on Sept. 10, researchers at Dartmouth's Geisel School of Medicine and Thayer School of Engineering are testing a critical element of a handheld device the team is developing that would alert crew members to high levels of calcium in their urine during space flight so they can take action.

As part of the Artemis lunar exploration campaign, NASA aims to deepen its understanding of the moon's surface and prepare for future Mars missions. The Artemis missions will target the lunar south pole, a region that holds scientific interest due to its permanently shadowed areas, which may contain water ice reserves vital for sustaining human exploration.

However, astrophysicist Susanne Pfalzner from Forschungszentrum Julich notes, "Several thousand celestial bodies are known to move beyond the orbit of Neptune."
