Water On Asteroid "We found the samples we examined were enriched in water compared to the average for inner solar system objects", said Ziliang Jin, a postdoctoral scholar from Arizona State University's School of Earth and Space Exploration and lead author of the study Jin and fellow cosmochemist Maitrayee Bose suggested the probe of water on Itokawa samples. "It's an area on the asteroid that's smooth and dust-covered".
Dr. Jin and his colleague, Dr. Maitrayee Bose, found a mineral called pyroxene in two Itokawa particles.
In 2029, an asteroid will get pretty close to Earth. That's because of a profitable mission by Japan's Hayabusa house probe, which gathered 1,500 particles from an asteroid named Itokawa and introduced them again to Earth.
On the annual Planetary Protection Convention being held this week in Maryland, scientists mentioned the large ranging analysis alternatives that the asteroid flyby will present, whereas providing insights into what most people can anticipate when the rock makes its cross.
Itokawa is 1,800 feet long and 700 to 1,000 feet wide - roughly 10 times the size of a football field.
It was launched in May 2003 and landed on the asteroid on November 2005 to collect samples in the form of tiny grains.
The NanoSIMS measurements revealed the samples were unexpectedly rich in water.
"Itokawa minerals contain water contents of 698 to 988 parts per million weight, after correcting for water loss during parent body processes and impact events that elevated the temperature of the original parent body", the scientists said. Johnson said that FEMA and NASA will be continuing to work together in conducting frequent exercises and this in turn helps them to work side by side and learn to meet their objectives and needs that has been given in the White House National NEO Preparedness action plan.
"In addition, the minerals have hydrogen isotopic compositions that are indistinguishable from Earth". This discovery suggests impacts from other asteroids during the early parts of Earth's history may have sourced much of the water for the planet's oceans.
"These exercises have really helped us in the planetary defense community to understand what our colleagues on the disaster management side need to know", NASA's Planetary Defense Officer Lindley Johnson said in a statement. On April 13th, 2029, the asteroid is generally known as Apophis will cross by Earth at a distance of simply 19,000 miles.

Two Israeli Soldiers Wounded in Shooting Incident on Gaza Border
Israel says its blockade is necessary to stop weapons reaching Hamas, which has fought three wars with Israel in the past decade. Some two million Palestinians live in Gaza, whose economy has suffered years of blockades as well as recent foreign aid cuts.
