Brief sightings from sts missions, perhaps there are those with further information who would like to post some higher res footage. completed as requested

A couple of things come to mind.

The moon shot, I honestly can't figure. My best guess is a small cosmic particle or tiny asteroid/meteorite being affected by the Moon's gravity as it falls down to the surface of the Moon.

The others look like either satellites or other planets or bodies orbiting the Sun because of their glow and steady movement.

Looks like ice being caught by the positional jets.

You can see one firing in the middle clip..
