The Mars Rovers: Sojourner Nasa Science For Little Ones

In a preceding study, Lagain’s group developed a crater detection algorithm that uses high-resolution pictures of the surface of Mars to determine compact influence craters, acquiring about 90 million as small as 50 meters in diameter. In this study, they have been in a position understanding to isolate the most plausible ejection website — the Karratha crater that excavated ejecta of an older crater named Khujirt. “This meteorite recorded the 1st stage of the evolution of Mars and, by extension, of all terrestrial planets, like the Earth,” said Valerie Payré, a postdoctoral researcher in the Division of Astronomy and Planetary...
