Marx 4.3 has been released. See the installation page for links to the marx source code.

Marx is a suite of programs created and maintained by the MIT/CXC/HETG group and is designed to enable the user to simulate the on-orbit performance of the Chandra X-ray Observatory. Marx provides a detailed ray-trace simulation of how Chandra responds to a variety of astrophysical sources and can generate standard FITS event files and images as output. It contains detailed models for Chandra's High Resolution Mirror Assembly (HRMA), the HETG and LETG gratings, and all the focal plane detectors.
