Men may sleep worse on nights during the first half of the lunar cycle
Write a comment
Men's sleep may be more powerfully influenced by the lunar cycle than women's, according to a new study from Uppsala University, now published in the journal Science of the Total Environment.
Previous studies have produced somewhat conflicting results on the association between the lunar cycle and sleep, with some reporting an association whereas others did not. There are several possible Chinese astronauts return to earth after 90-day mission
Write a comment
Three Chinese astronauts returned to Earth Friday after completing the country's longest-ever crewed mission, the latest landmark in Beijing's drive to become a major space power. The capsule carrying the trio deployed its parachute and landed in the Gobi desert at 1:34 pm local time (0534 GMT). "It feels very good to be back!," Tang Hongbo told state broadcaster CCTV after the 90-day mission, a record for China. Path set for commercial communications around the Moon

ESA confirmed a contract signature yesterday with Surrey Satellite Technology Ltd (SSTL) to be the main customer for their Lunar Pathfinder satellite launching in 2024 that will provide communications services around the Moon.
European facility prepares for haul of samples returning from planetary bodies
Write a comment
The Institute of Planetary Research at DLR (German Aerospace Center) is starting construction of a new Sample Analysis Laboratory (SAL) dedicated to the study of rock and dust samples from planetary bodies such as asteroids and the Moon. The first phase will be operational by the end of 2022, on time to welcome samples collected by the Hayabusa2 mission, and fully ready by 2023.
SpaceX's tourist crew 'healthy, happy and resting'
Write a comment
SpaceX's all-civilian Inspiration4 crew are "healthy, happy and resting comfortably," the company said Thursday in its first update since the pioneering mission blasted off from Cape Canaveral the night before.
The four American space tourists "traveled 5.5 times around Earth, completed their first round of scientific research, and enjoyed a couple of meals" before going to bed, Elon Musk's company said.
Musk tweeted that he had personally spoken with the crew and "all is well."
After waking up, they will get their first look out of the Dragon ship's cupola—a large observation dome that has been fitted onto the vessel for the first time, in place of a docking mechanism.
Billionaire Jared Isaacman, physician assistant Hayley Arceneaux, geoscientist Sian Proctor and aerospace data engineer Chris Sembroski are orbiting the globe at an altitude that at times reaches 590 kilometers (367 miles).

Europe's Spaceport in French Guiana is performing the first combined test in preparation for the inaugural flight of Ariane 6, Europe's new generation launch vehicle.
This test confirms the operations and electrical and mechanical equipment required for integration of the upper part of the launch vehicle. The procedures are carried out in conditions representative of a launch campaign. A major step of this test involves the closure of the Ariane 6 fairing around the payload.
Preparations started in May 2021 with a de-risking campaign of the mechanical operations.
The fairing, built by Ruag Space in Switzerland, stands 20 m high and 5.4 m in diameter. It protects payloads from the thermal, acoustic and aerodynamic stresses on the ascent to space.
This combined test was performed using a new integration dock, composed of a large white frame, with two mobile platforms adjustable to any level and accessible by fixed stairs and platforms, developed by the French space agency, CNES.
The assembly building has two halls: one for integration of the fairing and another where the payload is stowed in the fairing.
Soundblasting a satellite – time-lapse of testing

Verifying that a satellite will resist the sheer noise of the rocket launching it into orbit is a very important test that every mission must successfully pass.
“Typically satellites are tested inside purpose-built reverberant chambers, such as ESTEC’s own Large European Acoustic Facility sometimes described as the largest and most powerful sound system in Europe,” explains ESA test facility expert Steffen Scharfenberg, overseeing the test campaign together with ESA mechanical engineer Ivan Ngan. A very powerful noise generation system produces a uniform noise field thanks to the reverberation on the thick concrete walls of the chamber.

Write a comment
Global light pollution has increased by at least 49% over 25 years, new research shows.
This figure only includes light visible via satellites, and scientists estimate the true increase may be significantly higher - up to 270% globally, and 400% in some regions.
The study, led by the University of Exeter, examined light emissions from 1992 to 2017.
