> In the long term it might be easier to terraform a planet like Venus than it is to terraform a planet like mars.
One day on Venus is 224.65 Earth days. You won't be able to change that, even in the long term.

“It has until recently been assumed that the rotation rate or day-night cycle of Venus would have to be increased for successful terraformation to be achieved. More recent research has shown, however, that the current slow rotation rate of Venus is not at all detrimental to the planet's capability to support an Earth-like climate. Rather, the slow rotation rate would, given an Earth-like atmosphere, enable the formation of thick cloud layers on the side of the planet facing the sun. This in turn would raise planetary albedo and act to cool the global temperature to Earth-like levels, despite the greater proximity to the Sun.”
You still need to deal with the nasty chemical composition of the atmosphere, but that might be doable somehow. Your airship also needs to be massive and sturdy enough to shrug off hundred mile an hour winds.
The Chicxulub impact is estimated at 10^24-10^25 joules. So we need 10k-100k Chicxulub impacts in such a way that the energy is perfectly translated into Venus’s rotational energy.
That’s what, a billion tons of antimatter-matter reacting?
I don’t think we’re going to have a 24 hour day on Venus anytime soon.
