New Ring Around Saturn

The Fun Guy writes "From the New York Times: 'In its first month orbiting Saturn, the Cassini spacecraft has detected a new radiation belt in an unexpected place, its invisible swarm of trapped high-energy particles circling the planet inside the inner edge of Saturn's signature disk of luminous rings.' Cassini has also seen 'a striking glow emanating day and night from the planet's largest moon, Titan.' A moon that shines with unborrowed light!"

    The rings are icy chunks of matter. Radiation is not. Technically, it's not a ring.

      It matters because a lot of people are not knowlegable about astronomy, but have a lot of curiosity. They rely on little articles they read here and there for their information, including headlines they read on Slashdot. Misinformation doesn't do anyone any good.

      It also matters because astronomy is to a large extent funded by public money. The people paying the bills for mega telescopes and space missions deserve to know the truth about the discoveries that they pay for.

      Oh really? Where does it say that rings have to be made of matter? It is entirely conceivable that ring can be used as a synonym for belt, particularly in this instance. Sure, radiation belts are typically called "belts" but there's no reason why they can't be called "rings".

      You might as well be a pedant and say that because they're not made of gold and don't have diamonds in them and they don't fit on your finger and they're not solid the things around Saturn aren't rings. Technically they're a loose conglomerate of chunks of matter orbiting a planet at a lower altitude than that planet's Roche limit, but that's a bit of a mouthful.

      There's a very good reason one is call rings and one is called belts. Look at the picture. Sure it's possible to have a radiation ring and a rock/ice belt, but that doesn't change the fact that a radiation belt was found.

      Uhh, a ring is simply a topological structure. That means it is mathematical in nature--a geometrical construction. It has nothing to do with matter or energy each of which may take on such a geometry. Indeed, there is quite a debate in the physical sciences as to what "matter" really is--because at a deep enough level, everything looks like energy events. Whatever "reality" is, it certainly isn't what you tell me it is.

    Cassini Significant Events
    for 07/30/04 - 08/04/04

    The most recent spacecraft telemetry was acquired from the Goldstone
    tracking station on Wednesday, August 4. The Cassini spacecraft is in an
    excellent state of health and is operating normally. Information on the
    present position and speed of the Cassini spacecraft may be found on the
    "Present Position" web page located at
    http://saturn.jpl.nasa.gov/operations/present- posi tion.cfm .

    The S02 background sequence concluded with the execution of a Reaction Wheel
    Assembly bias activity. S03 began execution on Friday July 30. Initial
    activities included the loading of Instrument Expanded Block files, and
    uplink of Cosmic Dust Analyzer (CDA) flight software (FSW) version 9.2.4.
    The CDA FSW checkout is scheduled for mid August.

    Science activities this week mostly centered on Saturn observations. The
    Magnetospheric and Plasma Science (MAPS) instruments began a campaign to
    study the influence of the solar wind on Saturn's aurora, while Optical
    Remote Sensing (ORS) instruments observed Saturn's south pole and aurora. In
    addition, the Radio and Plasma Wave Science (RPWS) instrument observed
    Saturn's kilometric radio emissions. RPWS team members also gave a
    presentation to the flight team recapping science results that had been
    presented at last month's Committee on Space Research (COSPAR) meeting in
    Paris, France. Besides Saturn observations, the Imaging Science Subsystem
    (ISS) observed the trailing side of Iapetus, which will only be seen on a
    few occasions during tour.

    In the last week, 747 ISS images arrived and were distributed. So far since
    Approach Science began, 15896 ISS images and 4614 Visual and Infrared
    Mapping Spectrometer (VIMS) cubes have been returned.

    In preparation for the Huygens Probe mission early next year, the Spacecraft
    Operations Office (SCO) Integrated Test Lab has completed ten probe relay
    fault case tests. Eight tests passed completely. One of the failed cases
    was an incorrect fault injection and will be repeated at a later date. The
    second failed case is currently being reviewed.

    A project briefing was held as part of the Science Operations Plan update
    process for S05. This process will complete on Friday, August 6 and a
    handoff package presented to the leads for the Science and Sequence Update
    Process.

    Assessment meetings were held to review all of the requested changes to the
    S08 and S09 sequences as part of the Aftermarket process. It appears that
    all requested changes will fit within available resources. The Target
    Working Teams and Orbiter Science Teams will be reviewing the requests over
    the next two weeks and will provide their recommendations at the decision
    meeting for S08 scheduled for August 13 and for S09 on August 17.

    Development of S04 continued this week. A Preliminary Sequence Integration
    and Validation (PSIV) Science Allocation Panel (SAP) Meeting, Simulation
    Coordination meeting, and Simulation Procedure Review meeting were held.
    The simulation meetings were to coordinate testing of a first time use of
    Inertial Vector Definition in a Radio Science boresight calibration
    activity.

    The Navigation team reported that the post solar conjunction separation
    angle is currently about 20 degrees. Tracking data quality has improved
    significantly.

    The Multi Mission Image Processing Laboratory (MIPL) is performing
    certification testing of the Solaris 9 upgrades authorized by the Project as
