On the descent of the fairings into the atmosphere how is stability provided?

Why does it not start to rotate in a uncontrollable fall but reenter gently without apparently damage on the interior side?

Q: "On the descent of the fairings into the atmosphere how the stability is provided? Does not start to rotate in a uncontrollable fall but reentry gently without apparently damages on the interior side.".

Source Elon Musk InstaGram:

A: "It has onboard thrusters and a guidance system to bring it through the atmosphere intact, then releases a parafoil and our ship, named Mr. Steven, with basically a giant catcher’s mitt welded on, tries to catch it.".

Like peanut butter on toast, it lands heavy side down; and not where you want it:

  • $\begingroup$ @Rob interesting photo of the fairing in the water. Was that still reuseable? $\endgroup$ – Slarty Mar 10 '18 at 20:46
  • $\begingroup$ @Slarty - AFAIK it landed that way and was recovered floating, so stuff inside would be OK but the outside might not meet some Standards after contacting sea water. $\endgroup$ – Rob Mar 10 '18 at 21:08
