Watch: SpaceX Dragon capsule breathes fire during crucial hover test


It Makes Sense Though...

If you think about the challenge of deceleration from a purely "basic physics" perspective (i.e. conservation of momentum), then the heavier the capsule, the more energy it will take to decelerate it, using


So by ejecting the heatshield before the decelerative burn, you are basically going to get a greater velocity change [through the deceleration] for the same energy [fuel] cost.
