"We found the samples we examined were enriched in water compared to the average for inner solar system objects", said Dr. Ziliang Jin, lead author of the study. "Hayabusa touched down twice on the asteroid and collected a small amount of dust, despite the failure of the mechanism designed for the goal". In two of the five particles analyzed, the team identified the mineral pyroxene. "That makes these asteroids excessive-precedence targets for exploration", researcher Maitrayee Bose advised CNN, going to on argue that scientists ought to continue gathering samples from house rocks in a bid to higher perceive the place they got here from and the way they fashioned.
According to the researchers, the latest findings provide an alternative explanation to previous hypotheses of where water on Earth came from. If you are around in April in a decades time, the asteroid will even be able to see by the naked eye.
The Japanese Aerospace Exploration Agency, also known as JAXA, sent the Hayabusa probe to Itokawa back in 2000.
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.
Planetary scientists think that Itokawa is the remnant of a parent body at least 12 miles (19 km) wide that at some point was heated between 1,000 and 1,500 degrees Fahrenheit (538-816 degrees Celsius). More research is needed, but the good news is that the Hayabusa 2 probe managed to extract new samples from another asteroid.
To figure out if asteroids like Itokawa were the source of water on Earth, we looked at the ratio of two forms - or isotopes - of hydrogen: hydrogen and deuterium. In the aftermath two of the fragments merged and formed today's Itokawa, which reached its current size and shape about 8 million years ago.
The measurements revealed the samples were unexpectedly rich in water. "But our best guess is that they were buried more than 328 feet (100 m) deep within it", Dr. Jin said. These minerals are also similar to those found on Earth.
"Sample-return missions are mandatory if we really want to do an in-depth study of planetary objects", she said.
The chief of Response Operations Division of FEMA, Leviticus Lewis said that emergency managers want to know about how, when and where would be the impact of the asteroid and also about the extent and type of damage that could be caused.
