(HST) has adequate angular resolution to separate the light from the moons from that of Haumea. Photometry of the Haumea triple system with HST's NICMOS camera has confirmed that the spectral line at 1.6 um that indicates the presence of water ice is at least as strong in the moons' spectra as in Haumea's spectrum.

The moons of Haumea are too faint to detect with telescopes smaller than about 2 metres in aperture, though
