¤·····Subject: Updated Mars 2012 Map and Rotational Video

Received; 31 July 2012 at 06:53 JST

 

Hi,

Just to let everyone know that I have spent time in the last month making improvments to my Mars 2012 Albedo Map and Mars Rotational Animation to better match the surface details on the orginal images and to remove some minor artefacts introduced during the blending process. 

 The attached image shows a comparison between the original 7 images used to make the albedo map and frames from the animation video at the same CMs. The video was was created in Winjupos from the albedo map from the 7 images- so making the whole process go full circle.

 


Hope you like the results which can be seen at;

Dear Masatsugu,
   I suspect that you are right about the Parkinson's having come on gradually
 at first--I think it can be perceived as tiredness, fatigue, stiffness.  I do
 hope the medications (Sinemet I recall) has been helpful.  I suppose it must
be very difficult for you to slow down given your ambition and inquisitiveness
--it may be lucky that Mars is not in good position this year.
   I have been rather overworked this summer, and actually all year (last year
 I also had the deaths of my parents to deal with).  I made astronomy-related
trips in January (to
Austin, Texas), in February (to London for Astrofest and
then to Nice and
Paris), and again in May/June (3 weeks for the annular eclipse
and the transit of Venus), then again last week (to
Flagstaff for the First
Light of the Discovery Channel Telescope and to see Neil Armstrong).  Needless
 to say, these absences must be paid back, and since my main job is to run a
neurodevelopmental disorders program, here, I have been tasked heavily with
keeping that running, often short-staffed as many colleagues are also on vacations
This week I also have to prepare and present a major presentation for the
state of Minnesota on neurodevelopmental disorders; a complex and difficult
subject.  The hard thing is just finding time for it.
   Then I have finished translating James Lequeux's biography of Le Verrier
(from French), I still have to write up the transit observations I made at Lowel
l with the coronagraph Paolo Tanga brought from Nice, and I also have to rush
to the end of a Galaxies book I have been working on for many years now (with
Julian Baum and Chris Conselice).  I also have a new edition of a book on transits
 (expanded to cover eclipses and occultations) with John Westfall and am also
starting to gear up for a book on the Air Force Moon-mapping project at Lowell
and the astronaut training in and around Flagstaff, which is a geological
 wonderland (I had hoped to get you to Lowell sometime, but now it appears the
 window of opportunity has passed).
    Whew!  I really have hardly a spare moment these days, my head spins, and
when I do have a spare moment I am not inclined to spend it on writing.  Also,
 Mars is as far from my mind as it is from us in space these days.
   The upshot is: I don't think I can realistically write anything new; but perhaps
I can dig out an old essay on Mars for you and you can publish that if you wish.
Let me see what I can find.

   With best wishes to you,

Hi Guy these two images conclude a most rewarding imaging session from the 24th, with Jupiter climbing from 24 to 31 deg alt throughout. I would never have believed such seeing was possible at that altitude. I also imaged on the 23rd and have yet to complete those, as the 24th's stole my attention rather.

  Attached here is a montage with the images from the latest releases of MRO MARCI Weekly Weather Peport.

Adding the following MRO MARCI images may show a completegcurvehof the Alba cloud's activity beautifully showing the second maximum.
  Though I am still chasing now tiny Martian disc every clear evening, orographic activities of the huge volcanoes might almost be impossible to catch visually (CMO imagers' Big Guns still can, I guess)

¤·····Subject: STARTLING NEW DEVELOPMENT AT THE SOUTH POLE OF TITAN...FROM CASSINI

Received; 11 July 2012 at 05:26 JST

 

July 10, 2012

Dear Friends and Colleagues,

Cassini's recent travels to high orbital inclination around Saturn have
already won us some startling new finds.

Yesterday, it was our first views of Saturn's rings in about two years
that brought new revelations and insights concerning the orbits of tiny,
gap-forming moons in the rings and their likely interactions with the
ring particles they orbit among.

Today is even better.  Today, the Cassini imaging team is releasing a
near-true-color image and a movie that reveal a swirling, whirling
vortex forming high in the atmosphere overlying the south pole of Titan,
Saturn's largest moon, as the moon's southern hemisphere slowly becomes
engulfed in the darkness of deep autumn.  We've long known that the
entire winter hemisphere of Titan can exhibit a polar `hood' of haze
made of condensing organic compounds.  We suspect that this maelstrom,
clearly forming now over the south pole and spinning more than forty
times faster than the moon's solid body, may be a harbinger of what will
ultimately become a south polar hood as autumn there turns to winter. 
Of course, only time will tell.

In the meantime, go to ...

        
http://www.ciclops.org/view_event/177/Titans_Swirling_South_Polar_Vortex?js=1

... and check out the motions and beautifully detailed cloud patterns --
very likely the result of open-cell convection -- already visible in
this fascinating phenomenon that we on Cassini have been fortunate to
capture, for the first time, in the process of being born.

(Note:  Attached please find an image advisory released to the public
only a short time ago.)

Enjoy!

CASSINI FINDS VORTEX FORMING OVER TITAN'S SOUTH POLE

 

With its recent excursion out of Saturn's equatorial plane, NASA's Cassini spacecraft has benefited from a bird's-eye view of the south pole of the planet's largest moon where its cameras spied a polar vortex in Titan's atmosphere.  Saturn, Jupiter, Neptune, Venus and Earth also have polar vortices.

 

Images captured by Cassini's imaging team during a flyby on June 27 show the polar vortex, or a mass of swirling gas around the pole in the atmosphere of the moon, as it appears to execute one full rotation in about nine hours -- faster than the moon's rotation period.

 

A color image and a movie showing the vortex's rotation can be seen at http://ciclops.org , http://saturn.jpl.nasa.gov and http://www.nasa.gov/cassini .

 

"We've been watching this vortex become more developed in the last three to four months, and now, captured in exquisite detail, we're seeing finer scale features within the detached haze than have been seen to date," said Jason Perry, an imaging team associate at the University of Arizona, Tucson.

 

Since Cassini arrived in the Saturn system in 2004, Titan has had a visible "hood" high above the north pole. It was northern winter during this period, and much of the high northern latitudes were in darkness. But the hood, or an area of denser, high altitude haze compared to the rest of the moon's atmosphere, was high enough to still be illuminated by sunlight. The seasons have been changing since Saturn's August 2009 equinox signaled the beginning of spring in the northern hemisphere and fall in the southern hemisphere for the planet and its many moons. Now the high southern latitudes are moving into darkness. The formation of the vortex at Titan's south pole may be related to the coming southern winter and the start of what will be a south polar hood.

 

The massing of clouds around the south pole was seen as early as May 22 in infrared wavelengths by Cassini's visual and infrared mapping spectrometer. And Cassini's visible light cameras have seen a concentration of yellowish haze in the detached haze layer at the south pole since at least March 27.

 

These new, more detailed images are only possible because of Cassini's newly inclined orbits which are the next phase of Cassini Solstice Mission. Previously, Cassini was orbiting in the equatorial plane of the planet, and the imaging team's images of the polar vortex between late March and mid-May were taken from a location over Titan's equator. At that time, images showed a brightening or yellowing of the detached haze layer on the limb, or edge of the visible disk of the moon, over the south polar region.

 

"I believe we are seeing some fascinating events on the way to the formation of the south polar vortex, said Bob West, an imaging team member and an atmospheric scientist at the Jet Propulsion Lab in Pasadena, Calif. "Future observations of this feature will provide good tests of dynamical models of the Titan circulation, chemistry, cloud and aerosol processes in the upper atmosphere."

 

On Saturn, Jupiter, Neptune, Venus and Earth, similar vortices are centered on the north or south pole. However, the polar vortices on these planets each differ from each other in some ways. Titan's south polar vortex also appears extraordinary in that it contains what appears to be a cloud of condensing organic material, or material that contains carbon, hydrogen and nitrogen. The puffy structures in this cloud are especially intriguing.

 

Scientists interpret these new images to show open cell convection. In open cells, air sinks in the center of the cell and rises at the edge, forming clouds at cell edges. However, because the scientists can't see underneath the layer visible in these new images, they don't know what mechanisms may be at work.

 

"The structure inside the polar vortex is reminiscent of the open cellular convection that is often seen over Earth's oceans, said Tony Del Genio, a member of the Cassini imaging team at NASA's Goddard Institute for Space Studies, N.Y. "But unlike on Earth, where such layers are just above the surface, this one is at very high altitude, maybe a response of Titan's stratosphere to radiative cooling as southern winter approaches. But so soon in the game, we're really not sure."

 

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory (JPL), a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team consists of scientists from the U.S., England, France, and Germany. The imaging operations center and team leader (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.

¤·····Subject: CASSINI, NEWLY ON HIGH, RECOVERS SIKORSKY IN SATURN'S RINGS

Received; 10 July 2012 at 07:57 JST

 

July 9, 2012

Dear Friends and Colleagues,

One of the main contributing factors to the enormous success we on the
Cassini mission have enjoyed in the exploration of Saturn is the
capability to view the planet and the bodies around it from a variety of
directions.  Setting the spacecraft high into orbit above Saturn's
equator provides us direct views of the equatorial and middle latitudes
on the planet and its moons, while guiding it to high inclination above
the equator plane affords the opportunity to view the polar regions of
these bodies and be treated to vertigo-inducing shots of the planet's
glorious rings.

After a residence time of almost 2.5 years in near-continuous equatorial
orbits, Cassini recently took off on a steeply inclined orbital
excursion that will send it above and below the rings, over and over
again, for three years.  Already, new results on Saturn's rings and its
largest moon, Titan, are in hand from our first few months on this new
trajectory.

As a dramatic opening, the Cassini imaging team is releasing today our
recent findings on the famed `propeller' features.  These features are
actually small, longitudinally limited, orbiting gaps in the rings that
are cleared out by bodies smaller than known moons but larger than
typical ring particles. First sighted a few years ago in our images,
their reappearance in approximately the position we predicted indicates
that we understand their behavior well enough to know where they should
be years later, but not well enough to get it exactly right. Our best
guess is that their orbits are being altered by interactions with the
particles in Saturn's ring ... interactions we are keen to understand as
they may hold a key to the behavior of newly formed planets growing out
of disks of matter in orbit around other stars in our galaxy and beyond.

To see our recent sighting of the propeller nicknamed "Sikorsky", after
Russian-American aviator Igor Sikorsky, go to ...

        
http://www.ciclops.org/view_event/176/The_Rings_Are_Back

... and have a look.

In the coming days, we will be releasing our latest,  rather startling 
results on the polar regions of Titan.  So, watch this space!

Here are some high resolution visible lights images of spot 1520 and surrounding. A brief clear spell allowed some images. Very windy which made things a bit of a nightmare. Seeing was mostly poor. Clouds came in again before any further attempts could be made so i count myself lucky to have managed anything.

Best Wishes

Hi,

Please find attached my albedo map of Mars for the 2012 apparition, based on several images taken around opposition and compiled using Winjupos.  


For more details have a look at the link below which also gives maps from the 2010 and 2007-2008 apparitions.

 I also hope to create a full rotation animation from this map in the next few weeks.

Thanks,

Hi Guys the sun was busier today  during another brief solar appearance. There were two impressive prominences and plenty of active regions, but still no really big spots.  

 All images SM90 SS on AP130 EDT @ 80inches efl
