Sofia @sofiafsantos.bsky.social · 13/04/2026Good article. The way communication is being done also doesn't help building trust. Though NASA-led, Artemis is a collaboration, something barely mentioned in the media. If you have space agencies contributing that you consistently forget to mention, they will eventually start distancing themselves. 130
