Updates On Maven and SAM
This month AMU engineering continues to share the amazing work of so many minds who all come together to explore and discover the past, present, and future of Mars.
Synopsis of this months news:
- Curiosity has taken samples from a new location (pictured above) and will be on the move making its way through Artist’s Drive on a new route toward new discoveries.
- Mars once had an ocean. So where did all the water go?
Curiosity Takes Another Sample
“NASA’s Curiosity Mars rover used its drill on Tuesday, Feb. 24 to collect sample powder from inside a rock target called “Telegraph Peak.” The target sits in the upper portion of “Pahrump Hills,” an outcrop the mission has been investigating for five months.
The Pahrump Hills campaign previously drilled at two other sites. The outcrop is an exposure of bedrock that forms the basal layer of Mount Sharp. Curiosity’s extended mission, which began last year after a two-year prime mission, is examining layers of this mountain that are expected to hold records of how ancient wet environments on Mars evolved into drier environments.
The rock-powder sample from Telegraph Peak goes to the rover’s internal Chemistry and Mineralogy (CheMin) instrument for identification of the minerals. After that analysis, the team may also choose to deliver sample material to Curiosity’s Sample Analysis at Mars (SAM) suite of laboratory instruments.
The rover team is planning to drive Curiosity away from Pahrump Hills in coming days, exiting through a narrow valley called “Artist’s Drive,” which will lead the rover along a strategically planned route higher on the basal layer of Mount Sharp.”

Ancient Oceans on Mars: where has the water gone?
“A primitive ocean on Mars held more water than Earth’s Arctic Ocean, according to NASA scientists who, using ground-based observatories, measured water signatures in the Red Planet’s atmosphere.
Scientists have been searching for answers to why this vast water supply left the surface. Details of the observations and computations appear in Thursday’s edition of Science magazine.
“Our study provides a solid estimate of how much water Mars once had, by determining how much water was lost to space,” said Geronimo Villanueva, a scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the new paper. “With this work, we can better understand the history of water on Mars.”
Perhaps about 4.3 billion years ago, Mars would have had enough water to cover its entire surface in a liquid layer about 450 feet (137 meters) deep. More likely, the water would have formed an ocean occupying almost half of Mars’ northern hemisphere, in some regions reaching depths greater than a mile (1.6 kilometers).”
