NUSTAR OBSERVATIONS OF THE ENERGETIC PWN N157B WE PROPOSE TO OBSERVE THE PULSAR WIND NEBULA N157B IN THE LARGE MAGELLANIC CLOUD FOR 100 KS WITH NUSTAR. N157B HOSTS THE FASTEST AND MOST ENERGETIC YOUNG PULSAR PSR J05376910 AND IT HAS A SIMILAR SPIN-DOWN ENERGY LOSS RATE AS THE CRAB. WE AIM TO DETECT DISENTANGLE AND CHARACTERIZE THE HARD X-RAY EMISSION (>8 KEV) FROM THE PWN AND THE PSR AND TO COMPARE ITS PROPERTIES TO OTHER PWN AND PSRS. WE WILL SEARCH FOR SPECTRAL BREAKS IN THE HARD X-RAYS AS WELL AS MEASURE THE BRAKING INDEX WHICH WAS SHOWN TO BE ANOMALOUSLY HIGH DURING MONITORING WITH RXTE. THE SUPER-STAR CLUSTER R136 WILL BE SERENDIPITOUSLY IMAGED OFF AXIS AND WE EXPECT IT WILL BE DETECTED UP TO>20 KEV. WE WILL MODEL THIS EMISSION AS WELL TO EXPLORE WHETHER IT ARISES FROM E.G. COLLIDING WIND BINARIES.
