Polaris Dawn project aims to prevent bone loss in space
Write a comment
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.

NASA's EZIE mission set for 2025 launch
Write a comment
In 2025, NASA will launch its first mission to image the magnetic fingerprint of intense electrical currents that flow high in our atmosphere when auroras shimmer above Earth's poles.
The EZIE (Electrojet Zeeman Imaging Explorer) mission is designed to make groundbreaking measurements of the auroral electrojets, electrical currents about 60 miles (100 kilometers) above the ground in a layer of Earth's atmosphere called the ionosphere, which separates Earth from surrounding space.
The mission features a trio of CubeSats, or small satellites, with an orbit that goes pole to pole to map the electrojets. Mapping the electrojets can give scientists greater insight into the physics of Earth's magnetosphere and help create better models for predicting the effects of space weather phenomena such as geomagnetic storms and auroras in the upper atmosphere and at Earth's surface.
Starship Super Heavy breezes through wind tunnel testing at NASA Ames

NASA and its industry partners continue to make progress toward Artemis III and beyond, the first crewed lunar landing missions under the agency's Artemis campaign.
SpaceX, the commercial Human Landing System (HLS) provider for Artemis III and Artemis IV, recently tested a 1.2% scale model of the Super Heavy rocket, or booster, in the transonic Unitary Plan Wind Tunnel at NASA's Ames Research Center in California's Silicon Valley.

Spacewalking is the new domain of the rich as billionaire attempts first private spacewalk
Write a comment
First came space tourism. Now comes an even bigger thrill for the monied masses: spacewalking.
The stage is set for the first private spacewalk Thursday. Tech billionaire Jared Isaacman will pop out of the hatch of his orbiting SpaceX capsule, two days after blasting off from Florida on a chartered flight that lifted him and his crew higher than anyone since NASA's moonwalkers. He partnered with SpaceX CEO Elon Musk to buy a series of rocket rides and help develop brand new spacesuits.
SpaceX is the first private company to attempt a spacewalk, until now the domain of just 12 countries. There's a reason why it's such a niche and elite group: Spacewalking is considered the most dangerous part of any flight after launch and reentry, and demands extensive training.

Amid Boeing's Starliner troubles, WA space industry thrives
Write a comment
It'd be reasonable to think Washington's space economy has a lot riding on Boeing's Starliner, the spacecraft that left two astronauts stranded on the International Space Station and headed back to Earth with an empty cabin Friday.
The astronauts were scheduled to return on Starliner in June after a week on the ISS, but thruster failures and helium leaks on the way there made NASA decide a trip back on the Boeing spacecraft was too risky. Boeing's troubles with Starliner date back years, including a flawed, unmanned test flight in 2019 that had to be repeated in 2022.
But, outside of some classified satellite jobs that pop up in South King County, Boeing's efforts in the Seattle area are largely centered on its commercial airplane business, according to industry experts. Instead, the biggest players in the Seattle area's space industry are Amazon, Blue Origin and SpaceX.
"The Seattle space ecosystem is small but mighty because we have companies here that cover the entire space supply chain," said Stan Shull, founder of space technology consulting firm Alliance Victory.
Shull said there are the space and tech giants like SpaceX and Amazon manufacturing thousands of satellites in their Starlink and Project Kuiper divisions, respectively, and Blue Origin with its rocket engines and spacecraft.
