Transition-Edge Sensors (TES) are a novel class of quantum microcalorimeters that promise to revolutionize astrophysics. Presently they are being developed for use as the next generation detectors for many classes of astrophysical observations. Singe pixel X-ray measurements at the Al-Kα line (1.5keV) have been measured with 2.1 eV precision, rivaling Bragg Crystal Spectrometers resolution. As these detectors are inherent spectrometers (with near 100 quantum efficiency in X-ray energies), configured in an array, they promise to provide near-perfect 4-dimensional (space, time and energy) observations of astrophysical phenomena. We discuss the current level of advancement of this technology and as an example we discuss some of the technical challenges faced to design and fabricate an Explorer-class satellite to observe the solar atmosphere.
