We’re not *always* weightless on the @Space_Station.

They are always being accelerated towards the earth. A change in direction is an acceleration.

Is this that low thrust electronic propulsion that’s been mentioned in the past? Do you physically notice yourself moving faster if your eyes are closed, or does it feel the same?

The acceleration is so small that it would be difficult to detect without doing a careful float like I show in the video.

It’s like playing with the smallest gravity vector ever… you know what I mean. It would be fun to plot your position during that and show it as a true parabola.

Yup! And that apparent gravity vector points sideways - technically could stand on a scale on an aft wall and register a small weight. You’re right, it would be an almost perfect parabola - distorted only by ventilation airflow.

Why don't you film out the window to see if there's anything flying about or were you told by the government that you're not aloud to in case you film something that would be chaught on camera

We film and take photos out the window all the time, and there are some great external facing video feeds available here: eol.jsc.nasa.gov/ESRS/HDEV/

Cool to see physics in motion! How much faster does the @Space_Station travel during a reboost?

Don’t quote me on this, but I believe this reboost was on the order of 1.5m/s delta V. For reference our orbital speed is roughly 7800 m/s.
