The longer there is between the sender and the recipient the greater will be the need for good communication. Unfortunately, the technical problems also grow with distance. Communication with spacespaces on missions in Deep Space therefore represents a particularly challenging challenge. How do you carry on finding and communicating with a probe with limited energy resources from the outermost corners of the solar system? How can one land a probe on Mars when it can take up to half an hour for a radio signal to back the distance from the earth to Mars. But in addition to the problems of communication itself, the Radil link is also used to control the space vessels safely through space and often also to conduct scientific measurements.

John Leif Jørgensen, a professor at DTU Space and involved in countless space missions, will talk about the challenges of communicating over really long distances, how to use these for deep-Space naviogation, for scientific measurements and about some of The techniques you might want to move on in the future.
