In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Titan and Enceladus Composition measured with Cassini INMS and CAPS: Implications for the formation and evolution of the Saturn system
J. Hunter Waite
(South West Research Institute, USA)
The Cassini Ion Neutral Mass Spectrometer (Cassini INMS) continues to return a wealth of information about the Saturn satellites, Titan and Enceladus. Earlier data from Titan indicated an unanticipated organic complexity in the upper atmosphere. Ion-neutral chemistry plays a key role in the reaction mechanisms that lead to this organic complexity as evidenced by the abundance of high molecular weight positive and negative ions observed by the Cassini Plasma Spectrometer (CAPS).
Recent results from Enceladus also indicate an unanticipated organic complexity in the plume gases emanating from the interior that is quite different from that at Titan. The organic composition indicates both primordial organics similar to those seen in comets, as well as olefins that may be the result of Fischer-Tropsch (F-T) reactions in the interior. The existence of F-T chemistry is consistent with the measureable presence of 40Ar and ammonia and is further evidence of a liquid interior.
A D/H ratio from water vapor that is similar to the long period comets Halley and Hale-Bopp speaks to the origin and formation of icy bodies in the outer solar system. The measured ratio of D/H of 3 x 10-4 is consistent with the recent Composite Infrared Spectrometer (CIRS) measurements of D/H in methane at Titan suggesting a similar origin for the materials that make up these two Saturn moons. Compositional measurements from both moons suggest an icy origin in the outer solar system followed by a partial devolatization in the Saturn nebula with loss of N2 and CO, but retention of primordial CH4 as recently reported in separate papers by Mousis et al. and Glein et al. in Icarus (see online papers).
