Supernova remnant (SNR) G299.2-2.9 is a unique example of the Type Ia SNR which allows us a detailed 2-D spectral study for both of the metal-rich ejecta and ambient structures. Such studies of the ejecta and ambient medium are essential to reveal the detailed SNe Ia explosion mechanisms and their specific environments, which would critically impact their utility in cosmology. The proposed studies of both of the Type Ia SN ejecta and ambient structures cannot be performed with young historical Type Ia SNRs, and the mid-aged Type Ia SNR G299.2-2.9 provides a unique opportunity. Thus, we propose a 640 ks Chandra observation of G299.2-2.9. The proposed observation will serve a legacy which will be an essential basis for a high resolution spectroscopy of Type Ia SNRs with IXO and Astro-H.
