Re: Congratulations to NASA and SpaceX!
Hi Karen, hi all,
As impressive and full of proudness to U.S. people this technical accomplishment might be, let’s not forget that this very same company (SpaceX) is on the verge of “obscuring” the stars for centuries to come with its 42 000 very bright satellites megaconstellation being launched every two weeks now and ongoing in the months / years to come.
This may not seem that big of a number to most us who are used to astronomical scales but as a comparison point, there are about 3000 active satellites in the sky right now. As another point of reference, the human unaided eye can see about 4500 star in a dark sky. Just imagine the effect on our long exposures of increasing tenfold that number but of bright and moving objects in between the stars...
Many predict it’ll be devastating to any radio and visual astrophotography, be it amateur or professional... If that proves to be the case, it might sadly be one of those “hope for the best” moment in regards to the hobby we all cherish.
Very “dark” ages to come in astronomy indeed. Better capture what you can, while you can... 🙁
