For the Mars Exploration Rover Mission, I work on the MDOT (Mission Data Operations Team) – our team covers the data making it from the point it reaches JPL to the end engineers and scientists. If our stuff is not working – everybody notices! Our group also handles a lot of things – from rebooting workstations, to creating software tools, to handling questions. If people don’t know who to call – they call us. We don’t necessarily fix all the problems (though we can quite a few) but we find the people who can (if it’s not us).
