In human missions to other planets and natural satellites (e.g., return to the Moon and future missions to Mars), there will be a need to provide video services for such functions as monitoring analysis, personal private video conversations and general public outreach. There is a desire to provide these services by leveraging terrestrial Internet concepts and technology. In this work we focus on the video performance mechanisms as they are impacted in a space environment where long range latencies and bit errors arise in the wireless/RF links. We provide results from experiments using open source implementations of commercial video standards. Both Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity (SSIM) are used as a performance metrics.
