I was watching my favorite weekly space show on YouTube, TMRO, and I learned about Astro Live Experiences (ALE.) They will soon launch two test satellites which will be able to provide a burst of 30-40 man made shooting stars at a prearranged time and place, for a fee.

Japanese company ALE is the first "space entertainment" company of which I am aware. The only event in the same ballpark was New Zealand based RocketLab's Humanity Star which caused a large amount of controversy. ALE's initial technology will allow a 200km radius of earth to see their multi-color shooting star show. According to the interview on TMRO, in the long term, they are planning to allow image rendering and even artificial aurora.

This type of business seems inevitable as we advance into space. I can see some benefits and some downsides to this technology. What do you all think of this?

I know some people here have strong opinions about space travel, which came up during the Elon Musk topics on Tildes. I wonder if, based on the limited information we have, people think Japan is taking the right approach with the space elevator; whether the cost estimate ($9 billion) sounds reasonable; and if you think they can succeed?

Hi,

How often are satellite images taken? Why are more periodic images takes with less resolution (is it a different process?)

for example https://zoom.earth takes every 12 hours, but on the most frequent ones i am not able to zoom much (before it switch to older ones)
