How does DS1's mission compare to other space missions?
NASA is tracking DS1 through use of the Deep Space Network, which is a set of radio telescopes that can receive data from spacecraft. DS1 will send back (or "downlink") telemetry which will tell NASA if the technology being tested on DS1 is working correctly.
