"F-22 Pilot Swaps in for Guardian at International Space Station" by Air & Space Forces Magazine - Article notes that #NASA #Crew10 pilot Nichole Ayers (Major USAF) arrives at ISS as #Crew9 commander Nick Hague (Colonel USSF) prepares to return to Earth. Each is a member of a crew rotation of 4, with other US military members. The article links these two due to focus on Air Force & Space Force, excluding Army & Navy on the crews. airandspaceforces.com/f-22-pil #space #military #aviation #avgeek

🚨 ESO analysis confirms that the INNA industrial megaproject would have a devastating and irreversible impact on the facilities at Paranal Observatory in #Chile.

➡️ Light #pollution would increase by at least 35% above ESO's Very Large Telescope, by a minimum of 5% above ESO’s Extremely Large Telescope and by at least 55% above the south site of the Cherenkov Telescope Array Observatory

➡️ Air turbulence would also increase, degrading seeing conditions by up to 40%

➡️ Vibrations from the project could seriously impair the functioning of the ELT and the VLT Interferometer, which are both extremely sensitive to micro-seismic noise.

➡️ Dust during construction is also problematic as it settles on the telescope mirrors and obstructs their view.

www.eso.orgNew ESO analysis confirms severe damage from industrial complex planned near ParanalAn in-depth technical analysis by the European Southern Observatory (ESO) has evaluated the impact of the INNA megaproject on the facilities at the Paranal Observatory, Chile — and the results are alarming. The analysis reveals that INNA would increase light pollution above the Very Large Telescope (VLT) by at least 35% and by more than 50% above the south site of the Cherenkov Telescope Array Observatory (CTAO-South). INNA would also increase air turbulence in the area, further degrading conditions for astronomical observations, while vibrations from the project could seriously impair the functioning of some of the astronomical facilities, like the Extremely Large Telescope (ELT), at the Paranal Observatory.

The lasers our Very Large Telescope (VLT) pierce the Milky Way… but what is that vertical glow just below? 🤔

That’s the zodiacal light: caused by dust grains in the Solar System, it's so faint that it’s only visible in the darkest skies, such as those of Chile’s Atacama Desert.

And the pristine night sky 🌌 in this region has always been intertwined with the culture and traditions of its indigenous people, discover how: eso.org/public/images/potw2511

A vertical image of the night sky. The Milky Way – a dense band of stars and dark dust lanes – crosses the sky diagonally. Four yellow laser beams coming from outside of the image converge towards the bright core of the Milky Way. The zodiacal light – a white, diffuse and faint smudge of light – stretches vertically from the horizon.

An image taken from orbit shows the potato-shaped satellite Phobos orbiting above Mars. The perspective shows Phobos very close to the Martian limb. Phobos appears predominantly grey, while the surface of Mars displays tones ranging from rusty red to the bluish hue of its external atmosphere layer. Craters on Mars are larger than those on Phobos.
