Huygens Landing on Titan to be Tricky

neutron_p writes "On Jan. 14, 2005, Huygens probe will plow into the orange atmosphere of Saturn's moon, Titan. It will be flying blind through hydrocarbon haze and methane clouds to a surface that could consist of seven-kilometer-high ice mountains and liquid methane seas. Scientists hope that Huygens will survive the plunge. I hope too, especially after Genesis mission accident, although condition were much better."

There is an interesting article (http://www.spectrum.ieee.org/WEBONLY/publicfeatur e/oct04/1004titan.html) in the current issue of IEEE spectrum. They discuss how a disaster was avoided by Boris Smeds who pushed for stringent tests of the communication between Cassini and Huygens. It turns out that the Italian manufacturers of the radio didn't take into account the significant doppler shift between both craft. As the firmware of the radio could not be remotely upgraded, Cassini's trajectory was altered (further away from Titan) to lower these doppler shifts.

Let's hope no other misfortunes turn up.
