NASA's MESSENGER Sends Flyby Data to Earth Using CCSDS File Delivery Protocol Developed for Deep Space by International Team

August 11, 2005 NASA's MESSENGER team is using the CCSDS File Delivery Protocol (CFDP), a highly specialised protocol designed to overcome space operations communications challenges, to download data captured during a successful flyby of Earth last week. A team of international space data communications experts collaborating through the Consultative Committee for Space Data Systems (CCSDS) developed CFDP to reliably and efficiently downlink files from a spacecraft even in the strenuous environment of deep space. Since the MESSENGER spacecraft's launch a year ago, it has successfully used CFDP to enable mission communications and will use it throughout its 7.9-billion kilometre journey to Mercury.
