As part of the VLBI tracking of the ESA's Huygens planetray probe, the R.C.Byrd Green Bank Telescope of the National Radio Astronomy Observatory equipped with the ESA/JIVE-supplied Mk5 recorder was the first to detect the Huygens' carrier signal at the frequency of 2040 MHz. The spectrum with resolution of 900 mHz is obtained with the JIVE's Huygens Software Correlator will be used for reconstruction of the vertical profile of the wind in Titan's atmosphere. You can also hear Huygens as detected by the GBT during the descent.
