  Updated imaging and photometric results from Chandra observations of SN
1987A, covering the last 16 years, are presented. We find that the 0.5-2 keV
light curve has remained constant at ~8x10^-12 erg s^-1 cm^-2 since 9500 days,
with the 3-8 keV light curve continuing to increase until at least 10000 days.
The expansion rate of the ring is found to be energy dependent, such that after
day 6000 the ring expands faster in the 2-10 keV band than it does at energies
<2 keV. Images show a reversal of the east-west asymmetry between 7000 and 8000
days after the explosion. The latest images suggest the southeastern side of
the equatorial ring is beginning to fade. Consistent with the latest optical
and infrared results, our Chandra analysis indicates the blast wave is now
leaving the dense equatorial ring, which marks the beginning of a major change
in the evolutionary phase of the supernova remnant 1987A.
