Here's some interesting commentary on the delta-v and the movie Gravity. https://www.rocketstem.org/2013/11/03/delta-v-gravity-situat...


Just considering the orbital heights, they fudged it a bit.

What makes it laughable is the inclination, the ISS is ~51 degrees and the Hubble is ~29.

That's something like a 3500m/s burn.
