AB: ABSTRACT: The advent of cryogenic microcalorimeters (operating at temperatures of $\sim$ 0.1 K) in ground-based and space-based astronomy promises a revolution of new discoveries. Particularly, Transition-Edge Sensors (TES) have demonstrated high-energy resolution measurements of soft X-rays of up to {\it E/$\Delta$E} $\sim$ 1500 (at 6keV) and with high temporal resolution of a msec or less in photon pulse detections. Fabricated into multiplexed arrays of single detectors, or position sensing macropixels, and placed at the focus of a Wolter optic would further yield high spatial resolution capability of 2 arcsec or less, thus producing unprecedented "3-D" solar observations. We report herein, on progress to date in the development of these detectors and particularly, with on-going work with the sounding rocket payload, the Advanced Technology Solar Spectroscopic Imager, which will debut a TES instrument operating in the 300eV - 1.5keV range to study active region magnetic reconnection. Furthermore, as part of our larger effort, we discuss also current technical developments and plans at the Lockheed Martin Solar & Astrophysics Laboratory to design a TES instrument (3 - 8keV range) for realization into a dedicated Explorer-class solar observatory in the next 5 - 10 years.
