When a question is closed, there may be multiple reasons. Sometimes folks will comment, sometimes not. In this case, you have multiple comments:
Wirelessly. Mostly radio. There are antennae on both the satellite side as well as earth side. Could you make your question more specific. –
Are you looking for details of radio communication? or the equipment used? or the protocols used? or any other details?
this question does not show any research effort
As noted at chandra.harvard.edu/about/spacecraft.html all communication goes through the Deep Space Network. –
Also note that there will be multiple streams of communication between a satellite and the earth. One omni-directional (low speed) channel for managing the satellite (commands to satellite) and a high speed one for data transfer (astronomical observation data from the satellite in this example). Each channel could use different frequencies, modulation, encoding and different protocols.
So a useful tack to try to get a question reopened is to deal with all the comments, then it will be reviewed in the reopen queue. If you don't deal with the comments, folks will usually vote to remain closed. Currently, you really haven't dealt with many of the comments at all.
