The Constellation-X mission planned for launch in 2015, will feature an array of Hard X-ray telescopes (HXT) whose bandwidth extends to \~ 70 keV. Several technologies are being investigated for fabrication of these optics, including multilayer Coated Electroformed-Nickel-Replicated (ENR) shells.

We are building a prototype HXT mirror module using an ENR process to fabricate the in dividual shells.This prototype consists of 5 shells with diameters ranging from 150 mm to 280 mm with a length of 426 mm.

This paper presents a progress update and focuses on accomplishments during this past year. In particular, we will present results from high energy full illumination tests, taken at the MPE Panter Test Facility. This work was supported in part by NASA Grant NNG05WC27G and CONX/NASA grant 44A-1046805.
