This is an amazing app that allows you to see (almost) live all the #satellites and #debris (in LEO*) that are in #orbit above our heads.
You can pick one #satellite and get many info, including its orbit.
yeah, it's completely crowded, but we keep launching more and more #rockets 🚀 and much more satellites, like if our ressources were unlimited.

This week, I had the opportunity to stay 2 nights at the Pic du Midi #Observatory, in the french Pyrénées. I captured some #timelapse from this site, which is still magical.
I was astonished by the dynamism of this observatory: new domes, new #instruments, new projects and new buildings. #Research in #astronomy in the metropolitan #France is performing like a charm.
I fully support its application
