The 2009 Mars Telecom Orbiter mission

This paper provides an overview of the Mars Telecom Orbiter (MTO) mission, and is an update to the paper presented at last year's conference. Launched in 2009, MTO will provide Mars-to-Earth relay services for NASA missions arriving at Mars between 2016 and 2020, enabling far higher science data return and lowering the telecom and operations costs for these missions. MTO carries an optical communications payload, which will demonstrate downlink bit rates from 1 Mbps up to and possibly exceeding 30 Mbps. MTO will also demonstrate the ability to autonomously navigate, and to search for and rendezvous with an orbiting sample, in preparation for NASA's proposed Mars Sample Return Mission. A to-be-defined science instrument will also be carried.
