The path of most resistance could help limit bone loss during spaceflight
Astronauts that have returned after spaceflights over three months may show signs of incomplete bone recovery even after one year on Earth, but adding in more resistance-based exercises during spaceflight may help limit bone loss. The small study, published in Scientific Reports, on 17 international astronauts found that while the shinbone partially recovers, the sustained bone losses after one year are equivalent to ten years of normal age-related bone loss on Earth.
Steven Boyd and colleagues imaged 17 astronauts (14 male, three female) before spaceflight, at return to Earth, and after six and 12 months of recovery. They conducted bone scans on the tibia (shinbone) and radius (forearm) to calculate the resistance of the bone to fracture (failure load), bone mineral in the bone tissue, and tissue thickness. The authors also recorded exercises such as cycling, treadmill running and deadlifting completed by astronauts in-flight and post-flight.
One year after flight the median results for 16 of the astronauts showed incomplete recovery of the shinbone. Median shinbone failure load, measuring bone strength, was reduced by 152.0 newtons from 10,579 newtons at pre-flight to 10,427 newtons after one year.

X-Bow Systems Inc. (X-Bow), a new non-traditional small business supplier of Solid Rocket Motors (SRMs) and defense technologies, has announced that its Pathfinder I, a mobile energetics factory demonstration unit (aka Rocket Factory In-A-Box) will be delivered this month to the US Air Force Research Laboratory (AFRL) in Edwards, California. Pathfinder I is part of X-Bow's groundbreaking, low-co Tenoumer Crater, Mauritania

Will we find 2021 QM1 before it finds us? Shenzhou XIII astronauts doing well after returning to Earth
The three crew members of the Shenzhou XIII have recovered from the physical effects of their six-month mission and will return to routine training after medical assessment, according to the chief of the People's Liberation Army Astronaut Division.
Major General Jing Haipeng, commander of the division, told a news conference at the unit's headquarters in northwestern Beijing on Tuesday tha NASA's stratospheric balloon mission gets telescope with giant mirror
Telescopes designed to operate in space have to be constructed differently than those meant to operate on the ground. But what about telescopes that operate in between?
An upcoming NASA mission will use a balloon larger than a football field to send a telescope 130,000 feet (about 40,000 meters) above Antarctica. From that height, the telescope will study a phenomenon that chokes off star Canadian students prepare their CubeSats for launch
On June 29, 2022, Canadian students from Dalhousie University and the University of Victoria will be at Canadian Space Agency (CSA) headquarters to finalize the preparation of their CubeSats for launch. They are the first students from the Canadian CubeSat Project (CCP) to reach this important milestone, confirming their miniature satellites are qualified to be launched into space and deployed f EGNOS technology for Africa - ESA signs deal with ASECNA
European technology that allows satellite navigation signals to safely guide aircraft down for landing in the majority of Europe's airports will now be put to use across Africa and the Indian Ocean. ASECNA, the Agency for Air Navigation Safety in Africa and Madagascar, and ESA has signed an agreement to deploy a Satellite-based Augmentation System (SBAS) across a service region of more than 16.5 NASA previews 'emotional' impact of James Webb images ahead of release
The highly anticipated first photos from the $10 billion James Webb Space Telescope provided scientists with an emotional experience, NASA officials said Wednesday, two weeks before their public release.
Thomas Zurbuchen, the head of NASA's scientific programs, said the telescope, which was launched into space in December, and its images are shedding light on "a new worldview."
