The GSFC/NIST collaboration has been working to develop close-packed arrays of high-resolution microcalorimeters suitable for use on Constellation-X. These microcalorimeters use superconducting transition-edge sensors (TES), which are read out with superconducting quantum interference devices (SQUIDs). Rapid improvements in resolution, the inherent ease of arraying, and the ability to multiplex the read-out channels make the TES technology a promising match to the Constellation-X requirements of 2-eV resolution at 6 keV and at least 32 x 32 pixels. The resolution goal has already been met for soft x-rays with single-pixel devices. We will report on our latest progress towards understanding and optimizing TES pixels, implementing arrays, and developing spaceflight worthy read-outs.
