The Japan/US Astro-E mission was to provide astrophysicists with broadband, high-resolution x-ray spectroscopy for high sensitivity observations of a wide variety of celestial x-ray sources. Astro-E was launched in February 2000, but did not reach orbit due to a launch vehicle failure. Recently, proposals in both Japan and the US have been approved to rebuild the mission and deploy it in early 2005. The unique features of Astro-E2, particularly those of the microcalorimeter x-ray spectrometer (XRS), are designed to complement the spectroscopic capabilities of the Chandra and XMM observatories now in operation. The energy resolution of 12 eV in a 32 pixel array will enable powerful diagnostics of high energy processes from measurements of L- and K-shell atomic transitions, including dynamical information, to be determined with high precision. The instrument utilizes a three stage cooling system capable of operating the microcalorimeter array at 0.060 K for about two years in orbit. We will describe the Astro-E2 microcalorimeter/cryogenic system, the scientific capabilities of Astro-E2, and the possibilities for improving the spectroscopic performance and extending the cryogen lifetime.
