"The role of liquid water in gully formation should... be reconsidered, raising the question of the importance of its occurrence in Mars' recent past," the researchers wrote in a news release. Initially, researchers thought that the Martian gullies were the runoff melted water ice or groun...
Although strong geomorphological evidence for many of these relationships has been apparent for 30 years, its scientific importance has only been recently appreciated because of direct geochemical measurements of water and ice features by surface robotic and orbital instruments.Victor R. Baker...
Scientists conduct field experiments in desert regions because the extremely dry conditions are similar to Mars. Researchers realized the importance of the varnish earlier this year when Bishop and Chris McKay, a planetary scientist at Ames, investigated carbonate rocks coated with iron oxides collected...
But aside from its importance as a resource, the ice also provides scientists with clues about long-term climate patterns on Mars. “If you had a mission at one of these sites, sampling the layers going down the scarp, you could get a detailed climate history of Mars,” said MRO Deputy...
Scientist Carl Agee tells how the meteorite could further the understanding of Mars. Associate administrator John Grunsfeld of the U.S. National Aeronautics and Space Administration (NASA) explains the importance of the finding that water molecules were formed because of contact with water within the...
“The fact that the groundwater isn’t as big of a process could mean that other things are,” Hiatt said. “It might magnify the importance of runoff, or it could mean that it just didn’t rain as much on Mars. But it’s just fundamentally different from how we think about [water...
Tesla and SpaceX, are big bets with the potential to change our lives. They are epic, water-on-Mars-like propositions with long-term horizons. Which is fitting, considering how long it took for NASA’s Mars Reconnaissance Orbiter (MRO) to be certain enough of water on Mars to make an ...
If there is no water, what will it be? On the earth, there will be no life and death like Mars and Saturn. Then there will be no human being. 英语作文:Saving water 节约用水 16 Water is precious,so we have to protect the water resources.We start from the day-to-day things,such ...
