Are We Going to Mess Up Outer Space Too?
As nations jockey for military edge in orbit, there is a growing threat from above
by Daniel Munro Updated 8:49, Jun. 19, 2024
"Over the past decade, however, space has become much more contested and harder to govern. Nearly 1,000 private companies now offer space-based products and services. Expanding #SatelliteConstellations offer better internet access in remote and developing communities, enabling more people to access online health care, work remotely, and connect with family and friends. Space technologies also support better weather and climate monitoring, improve navigation and transportation logistics, and enhance agricultural productivity through the use of land- and water-quality sensors. All this has contributed to a space economy with an estimated value of $447 billion (US), on a trajectory to reach $1 trillion by 2030. And missions focused on exploration and scientific discovery are expanding—including the US-led Artemis program that aims to land human beings on the moon for the first time in over fifty years.
"But this new space age poses substantial risks. #OrbitalDebris from inactive satellites, discarded rocket parts, and anti-satellite #weapons tests threatens the infrastructure on which our social and economic well-being now depends, as well as the lives of astronauts working on space stations. In addition to the 30,000 objects large enough to track, there are an estimated 1 million debris fragments—between one and ten centimetres in diameter—that are too small to be picked up by ground-based radar and surveillance networks. Experts put the likelihood of future collisions between these objects at near certainty, with potential for cascading and catastrophic damage including entire satellite communication systems being taken out and larger debris fragments falling to #Earth and threatening lives and #ecosystems."

Did you know that the experience of the starry sky is being lost to more and more people? An ode to the night sky and an introduction to the topic of #lightpollution with many references. Using my own landscape photos, I illustrate the impact of artificial light at night.
Among other things, inspired by following @JohnBarentine and @sundogplanets. Thank you!

ICYMI, we're loosing the night sky.
"When all these #megaconstellations are complete, there will be nowhere on Earth to escape to observe a dark, clean night sky."

Now this is the kind of good news we can use more of. Let's hope other countries follow Chile's example.

How light pollution causes more harm than realized
By Ashley Carter, April 26, 2023
"Not only are humans facing the effects of light pollution, but wildlife are as well. Animals are mainly disrupted through an alteration of migration patterns, sleeping habits and habitat formation. For example, turtles are guided by moonlight when they are migrating. Because of light pollution, turtles are unable to follow their typical migration patterns, often leading to death. Many animals are naturally drawn towards light, such as birds, which has resulted in large numbers of deaths in large cities.
"Especially harmful are the impacts of light pollution on marine ecosystems. Boats can often have underlight panels on their bottom side, which light up the water underneath. As a result, many marine species will move further away from the light areas, disrupting where they find shelter and form habitats. Prolonged exposure to light pollution among any form of wildlife can affect their hormones, skin coloration, thermoregulation and reproduction.
"Not only are animals needing to adapt to habitat degradation and climatic changes, but the unfortunate effects of light pollution are also disrupting daily behaviors that they rely upon for survival. We humans, who may not realize the harmful extent of such an issue, will find that their short and long term health will become greatly affected."

Why It’s Time for a Worldwide Lights-Out Program
A new Smithsonian exhibition delves into the issue of light pollution, with easy solutions offering an immediate change
April 14, 2023
"One-third of the world’s population can’t see the starry band of light in the night sky that makes up the Milky Way—the vast spiraled arms of our own galaxy. The stunning array is now rendered invisible for some 60 percent of Europeans and almost 80 percent of North Americans. And as light pollution literally makes the darkness disappear, all types of plants and animals, accustomed to cycles of night and day for millions of years, are being dramatically affected in ways both obvious and unknown. Just as a bright light coming into a bedroom window might interrupt the sleep of any one of us, darkness is a foundational need of untold floral and animal species; artificial light impedes their ability to rest, feed and reproduce."

#MilkyWay #DarkSkiesForAll thread:
RT @sundogplanetsJust over 3 years ago, I moved to a farm where I can see the Milky Way from my back door. Despite being an astronomer, I've never had that kind of personal access to a dark sky before, and it totally changed my relationship with the sky. ..

In this case, the answer to the question in the title might be "yes".
Again, astronomers get the spotlight, but the real tragedy is that the night sky is being transformed for every human being on this planet.
We all need #DarkSkiesForAll.

Image from 8min exposure of the sky, taken from Tiede, Spain, about 40° wide. The points are stars (you may need to open the image to see them). Two streaks are from airplanes, one from a meteor, and all the others from satellites. We are loosing the sky. #DarkSkiesForAll

Europe seems hell bent to ruin #DarkSkiesForAll. First their own sat constellation "for security", now solar farms in space?! Can we think of yet another way to screw up our common natural heritage?
RT @kim_borgen:
Just imagine you could collect solar power, in the order of GWs, and beam it down to the earth's surface. If that works, that would be a game changer for Europe's energy situation, and for humanity - Director General @AschbacherJosef of @esa at the opening of #CM22 on Solaris
