Interesting find! Earlier in the feed you can see a solid piece of oxygen [0] bouncing off the engine. The particle you mentioned is going past the spacecraft (forward), so I can't see it being solid oxygen. My guess is a piece of dust that is being illuminated, and the camera is picking up the reflection but is blurry, making the particle look bigger than it actually is.
