Here is where we will be posting some of the explorations and discoveries in our "neighborhood."
 
Below you will find images of our solar companions, and special pictures and updates.  Dig deeply.  There's lots of material here --- lots to discover.

Oxygen-rich atmosphere discovered on the Saturn moon "Rhea."

   Along with Europa and Ganymede, two of Jupiter's moons, and other locations in our solar system beyond Earth --- this Saturn moon now shows us that one of the most important elements necessary for life is more widely spread in our neighborhood than we had formerly imagined.
 
   We also find that Rhea seems to be composed mostly of the ice form of warer.  It can also be expected to hold its atmosphere since, with its 950 mile diameter, the mass provides enough gravitational force to hold its thin atmosphere, which is approx. 70% oxygen and 30% carbon dioxide.

Astronaut Alan Bean on the Moon in 1969

moonastronaut3d.jpg

This 3D picture was taken by Astronaut Charles Conrad and shows you work in progress on the Moon, from the "Apollo 12" flight of exploration on November of 1969. The area is in what is known as the Oceanus Procellarum, which is a lava plain that is considered to be about 3.1 billion years old.

 

 

 

In July, 2004

Our "Cassini" space explorer sent back this fantastic image of the Rings of Saturn

sat2drings1.jpg

This picture was taken from NASA TV. It shows "density waves" caused by the gravitational influence of Saturn's moons. This fine close-up shows us details that have never before been seen.

 

 

See below, for a spectacular artist's conception of the moon probe exploration.

The Probe To Saturn's moon, "Titan."

titan2d2.jpg

Here a NASA artist shows us the "Huygens" probe dropping from the "Cassini" spacecraft to the mysterious, shrouded surface of the "Titan" moon.

 

The atmosphere is mostly nitrogen, with thick clouds of hydrocarbons, very much like "smog" and the atmospheric pressure is approx. one and a half times that of our Earth.

The schedule for this probe of the moon is in December of 2004.

 

 

 

The Search for Life

With the Saturn Probe

saturn2d2.jpg

The image above is from the "Cassini" spacecraft and was taken and transmitted as the craft was making its final approach to the planet Saturn at the end of February, 2004. The picture was taken at 43.1 million miles from the planet.

You will notice that the spokelike markings, that were observed and filmed during the approach of the Voyager probe 23 years ago, are no longer visible. No one has any idea why this has happened.

 

The Saturn system survey start date is July 1, 2004. A flyby and close examination of "Titan," Saturn's largest moon, is scheduled a few days later. This is a preliminary activity to a scheduled probe into the "Titan" atmosphere on Jan. 14, 2005.

The "Cassini" spacecraft will release its "Huygens" probe and it will descend through the atmosphere of "Titan" where it may encounter a scene possibly not unlike the one depicted above by a project artist of the NASA/ESA/ISA endeavor.

There are good reasons why a probe to "Titan" makes sense. This largest moon of Saturn is flexed by the gravitational forces of Saturn to the extent that it has notably heated up. It also has an atmospheric pressure about that of Earth. It is also believed to have seas in liquid form.

The chemistry is considered to be somewhat different but it is very possible that some form of aquatic life may have developed. Even on Earth we have discovered primitive life forms living off of chemical compounds that would be fatal to humans.

So, the chance of finding life there is not at all out of the question, but it is not something that we actually expect to find. We will just have to keep exploring and learn what we can.

The European Space Agency "Huygens" probe lands on Titan on Friday, January 14, 2005

Titan, one of the moons of Saturn, is the largest moon in our solar system and has an atmosphere that is believed to be 50 percent denser than our own planet, Earth. It is an atmosphere that is rich in nitrogen, methane and other "exotic" gasses.

Many scientists believe that it is an atmosphere very much like that of the Earth several billion years ago, at a time when life may have begun on our planet.

An early, unprocessed image of the surface of Titan, as taken while the probe was descending. The picture was taken using the Descent Imager Spectral Radiometer.

Early pictures suggest the strong possibility of drainage channels and a black & white shoreline can also be seen in some of the images. And, in another image, taken from the surface, rounded-off blocks of what looks like ice embedded in other material, seems to go on and on to the horizon.

With Additional Processing, We Now Have The First Color Image On The Surface of Titan

titan2d4.jpg

What the scientists first believed might be ice blocks are now better understood to be the size of pebbles. It has also been found that the surface of Titan is actually somewhat darker than they had expected it to be. And, it seems to be a mixture of water and hydrocarbon ice. You can also see evidence of what seems to be erosion.

 

 

With Still Further Image Processing,

We Can Show You The Following...

This picture is a composite of images taken during the descent, from approx. 5 miles altitude.

 

These are important images of a truly historic moment in human history. We are honored to be able to share these with you at this time.

 

 

 

Another historic moment.  The "NEAR" space probe landing on the Eros asteroid.
