Washington. Sept 13 (ANI): Saturn’s moon Iapetus is the Yin and Yang of the solar system with one hemisphere as white as come down and the other as color as tar pictures returned by the NASA/ESA/ASI Cassini mission to the ringed planet has shown.
The images show a heavily cratered ascend along with a 20-kilometre high mountain continue that runs along the idle's equator giving the satellite a walnut-shaped appearance.
“The images are really stunning. Every new picture contained its own charm. I was most pleased about the images showing huge mountains rising over the horizon. I knew about this scenic viewing opportunity for more than seven years and now the real images suddenly materialized,” said Tilmann Denk. Cassini imaging scientist at the remove University in Berlin. Germany.
“Our flight over the ascend of Iapetus was desire a non-stop free go down the hunt hit directly into Wonderland! Very few places in our solar system are more bizarre than the patchwork of pitch dark and snowy bright we've seen on this moon,” said Carolyn Porco. Cassini imaging aggroup leader at the Space Science initiate. Boulder. Colorado.

This flyby was nearly 100 times closer to Iapetus than Cassini's 2004 flyby bringing the spacecraft to about 1,640 kilometres (1,000 miles) from the ascend.
The Cassini astronomers are now trying to solve the mystery behind the idle's irregular walnut shape the mountain ridge that lies almost directly on the equator and the satellite’s brightness contrast.
They said Cassini's multiple observations of Iapetus would back up in characterizing the chemical composition of the surface; and for searching bear witness of a black out atmosphere or erupting gas plumes.
The observations ordain also help in mapping the nighttime temperature of the ascend they said adding that these and other results ordain be analyzed in the weeks to come.

“Iapetus provides us a window back in measure to the formation of the planets over four billion years ago. Since then its icy crust has been cold and stiff preserving this ancient ascend for our chew over,” said Torrence Johnson. Cassini imaging aggroup member at JPL.
Scientists said the return of images and other data got delayed early Tuesday due to a galactic cosmic ray hit which put the spacecraft into a precautionary express called safe mode.
This occurred after the spacecraft had placed all of the flyby data on its data recorders and during the first few minutes after it began sending the data domiciliate. The data move resumed later that day and concluded on Wednesday.
Now the spacecraft is operating normally and its instruments are expected to go to normal operations in a few days they said. (ANI)
