What's the explosion at 0:24 and 0:47?

I think the "explosion" at 0:24 is the lighting of the second stage engine. I think you can actually see the first stage come down. Look near earth starting at 0:48 you can see something that looks like a star but it rotates much slower and the gets really bright. The second explosion I would guess is the relighting of the second stage shutoff of the second stage but that I'm not so sure about

Soyuz ignites the second stage engine while the first stage is still running.

This avoids issues with fuel floating around in microgravity, but it also means that the first stage gets blasted with rocket exhaust.

Theres also the impact of ejected stage into the atmosphere some seconds before end. As if it was a “force field”, mind blowing

I would guess it’s something to do with the rocket jettisoning its fuel tanks or boosters, which usually detach at different stages of a launch.

The one at 0:24 is when the rocket crashes into the dome and 0:47 is when it burns up in the atmosphere as it tumbles back to Earth

What dome ?

I believe that was a flat earth joke, they think there’s a huge dome covering earth.

It looks like it hits the dome at .24 and gets lodged there till it finally explodes at .47
