The InSight lander will study the deep interior of Mars and will address one of the most fundamental questions of planetary and solar system science: how do terrestrial planets
The category of rocky planets, also known as terrestrial planets
, includes (http://www.
Since the terrestrial planets
are much closer to the sun than the gas giants, they'll be more likely to be seen in transit.
They describe the discovery of the solar system, theories of its origin, how scientists constructed a timeline of the solar system and its major events, the role of meteorites, the chemical elements that make up the solar system, the birth of the Sun and the planets, how protoplanets became the terrestrial planets
, the formation of the Moon, the development of life on Earth, the formation of giant planets, the asteroid belt between Mars and Jupiter, and objects in the outermost solar system.
Narita has shown that, abiotic oxygen produced by the photocatalytic reaction of titanium oxide, which is known to be abundant on the surfaces of terrestrial planets
, meteorolites, and the Moon in the Solar System, cannot be discounted.
The study provides the first evidence that terrestrial planets
can form in orbits similar to Earth's, even in a binary star system where the stars are not very far apart.
By studying Vesta and Ceres, we will gain a better understanding of the formation of our solar system, especially the terrestrial planets
and most importantly the Earth," principle investigator Carol Raymond said this week.
The InSight mission will record the first-ever measurements of the interior of the red planet, giving scientists unprecedented detail into the evolution of Mars and other terrestrial planets
This discovery is exciting because we weren't certain that terrestrial planets
could form around one star of a binary star system," University of Auckland physics senior lecturer Nicholas Rattenbury said in a statement.
The team of researchers from France, Germany and the United States simulated the growth of the terrestrial planets
(Mercury, Venus, Earth and Mars) from a disk of thousands of planetary building blocks orbiting the Sun.
Previously published as Remote Sensing for Geologists: A Guide to Image Interpretation, the third edition adds chapters on alterations due to mineral deposits and hydrocarbon accumulations, modern analogs, geobotanical remote sensing, and mapping terrestrial planets
While astronomers already knew that stars accompanied by giant planets contain more heavy elements, this work suggests that chemistry could also flag the presence of smaller, terrestrial planets
