HR 8799 is the first multi-planet system that has been directly imaged. It contains three known giant planets enclosed by an inner and outer debris belt -- an architecture reminiscent of a scaled-up version of our own Solar system. We will discuss the first spatially resolved spectrum of the middle planet, HR 8799 c, acquired with VLT/NACO at 3.9-4.1 microns, where the continuum shape of the spectrum is suggestive of chemical non-equilibrium conditions in the atmosphere of the planet. We also describe our plans to characterize the other planets in the HR 8799 system, and to extend the wavelength coverage.
