I’m amazed there was no mention of LISA [0] — a space-based gravitational wave detector using 3 satellites flying in formation 2.5 million Km apart! Seriously cool engineering, planning to launch in 2035.

I remember reading about LISA when I was a little kid. Back then it was projected to launch in the far future of 2015. Now I would be surprised if it actually launches in 2035.
The university I studied at had a Gravitational Wave center under the Physics dept, and all the professors would joke about how LISA had been "less than a decade away" for 20 years.
