Huygens is expected to provide the first direct and detailed sampling of Titan’s atmospheric chemistry and the first photographs of its hidden surface, and will supply a detailed ‘weather report’. All Doppler radio measurements between Cassini and Huygens were lost as well; however, Doppler radio measurements of Huygens from Earth were made, though not as accurate as the expected measurements that Cassini would have made. In addition to the GBT, eight of the ten telescopes of the continent-wide VLBA in North America, located at Pie Town and Los Alamos, New Mexico; Fort Davis, Texas; North Liberty, Iowa; Kitt Peak, Arizona; Brewster, Washington; Owens Valley, California; and Mauna Kea, Hawaii, also listened for the Huygens signal.[7]. Long after launch, a few persistent engineers discovered that the communication equipment on Cassini had a potentially fatal design flaw, which would have caused the loss of all data transmitted by Huygens.
In early 2000, he sent simulated telemetry data at varying power and Doppler shift levels from Earth to Cassini. For the first time, astrobiologists were able to see through the thick atmosphere of Titan and study the moon’s surface, where they found lakes and seas filled with liquid hydrocarbons.
The Huygens SSP was developed by the Space Sciences Department of the University of Kent and the Rutherford Appleton Laboratory Space Science Department under the direction of Professor John Zarnecki.
The Huygens probe successfully landed on Saturn's largest moon Titan at about 11:30 UTC on January 14, 2005. Astrobiologists are studying what these liquid hydrocarbons could mean for life’s potential on Titan. When the mission was planned, it was not yet certain whether the landing site would be a mountain range, a flat plain, an ocean, or something else, and it was thought that analysis of data from Cassini would help to answer these questions.
The GC/MS was developed by Goddard Space Flight Center and the University of Michigan's Space Physics Research Lab. Still have questions? A tilt sensor measured pendulum motion during the descent and was also designed to indicate the probe's attitude after landing and show any motion due to waves. A penetrometer instrument, that protruded 55 mm past the bottom of the Huygens descent module, was used to create a penetrometer trace as Huygens landed on the surface. Huygens detached a month later than originally planned (December 2004 instead of November) and approached Titan in such a way that its transmissions travelled perpendicular to its direction of motion relative to Cassini, greatly reducing the Doppler shift.[20].

First, although they could not receive any signal from Earth because it was in front of the Sun, Earth could still listen to them. Some engineers, most notably ESA ESOC employees Claudio Sollazzo and Boris Smeds, felt uneasy about the fact that, in their opinion, this feature had not been tested before launch under sufficiently realistic conditions.
Overview of the Cassini-Huygens mission to Saturn.
The video below shows a replica of Huygens undergoing wind tunnel tests. There was a transit of the Earth and Moon across the Sun as seen from Saturn/Titan just hours before the landing. Measurements from the Cassini spacecraft have found a body of liquid water the size of a Great Lake on Enceladus. Over 280,000 people receive our email newsletter. The first scientific data arrived at the European Space Operations Centre (ESOC) in Darmstadt, Germany, this afternoon at 17:19 CET.
The probe remained dormant throughout the 6.7-year interplanetary cruise, except for semiannual health checks. Three imagers, sharing the same CCD, periodically imaged a swath of around 30 degrees wide, ranging from almost nadir to just above the horizon. Put a spin on it then maybe they'll get to the cause of the mystery. why doesn't anybody try to show me why the earth is NOT flat ? Data that Huygens transmitted during its final descent and for 72 minutes from the surface included 350 pictures that showed a shoreline with erosion features and a river delta.
Titan is a truly unique moon, and studying Titan can help astrobiologists theorize about the potential for life on the tiny world. Even the stones immediately facing Huygens were rendered to match the photograph of the landing site returned from the probe, which is revealed at the end of the animation.
The first full mosaics of Titan’s surface were acquired on May 13, 2005. That wind tunnel test is like studying the leaves on the ground to figure out which branch they came from. “The teamwork in Europe and the USA, between scientists, industry and agencies has been extraordinary and has set the foundation for today’s enormous success,” concludes Jean-Jacques Dordain.
Very large radio telescopes on Earth were also listening to Huygens' 10-watt transmission using the technique of very long baseline interferometry and aperture synthesis mode.
The AstrobiologistsNAI University of Hawaii, Manoa Team member Toby Owen is a Co-I and interdisciplinary scientist on the Cassini mission, and one of the scientists that led the mission to a new start as a NASA-ESA mission.
Preliminary data indicate that the probe landed safely, likely on a solid surface. This work will also help determine processes that could lead to habitability on the moons of giant planets around distant stars. “It is like snow that has been frozen on top,” said Erich Karkoschka, a co-author of a paper published in October 2012.
