That is the Oxygen tank, inside Stage 2. Looking at the intake for the engine.
This has been show before on different missions.
In order to re-light the engines, the fuel needs to be near the intake, which in Zero-g, is not a given on a mostly empty stage.
Typically upper stages use ullage boosters, small rockets that accelerate the stage enough to push the gas to the intake, where the pump on the engine can suck it in, and once the engine starts, the acceleration forces the propellants to the back wall.
