Apollo 17 was locked into a moon-stick over the moon's surface in 1972, which demorated by a special device. Mars does not have astronauts, but a group of researchers realized that they are just the tools for similar tests with Martian Influenza that they work.
In a new paper in Science, the researchers explain how they used sensors who were in a position; using the rover Curiosity and converted into graphs, which modifies changes in hard pull. However, it gave them the chance to measure the simple toy from ancient rock sharks on Ben Sharp, which rises 15 kilometers from the base of the Crack Crater and is worried to have been rising since 2014. The results? It appears that the density of these rock scenes is much lower than expected.
Just like smartphones, minds carry speed-makers and garacoscopes. Moving your smartphones to let these sensors determine what the location is and how it is. Sensory sensors can do the same but with much more detail, and # 39; play an important part in Martian's surface address on each driver. By recognizing rover guidance too, its & # 39; allows engineers to accurately identify their instruments and multiply antenna, high quality.
With a happy accordion, the rover speed accelerators can be used as the Apollo 17. multiplier. The landmarks will find their landmarks. planet when the rover is still. Using engineering data from the first five years of the mission, authors had a & # 39; a paper that describes Mars's funny chain on the rover. How does a greeting stretch up Sharp Sharp, which's a? I would add more globalization – but scientists are not as big as expectations.
"The lowest levels of Mount Sharp are incredibly poor," said the author Kevin Lewis from the University of Johns Hopkins. "We know that the lowest levels of the hill were buried over time. They make them closer closer. But this product suggests that the burial is not tasted with a lot of material like we thought. "
Science from Mars' s sadness
The Apollo gave 17 slabs away their bag throughout Taurus-Littrow Valley, occasionally stopped to catch 25 measures. Lewis has explored Martian's graphics areas using data collected by NASA managers and knew the Apollo 17 criterion.
The Science paper uses more than 700 measurements from Curiosity velocitors, which were built between October 2012 and June 2017. This data was calibrated to generate "sound", such as the impact temperature and heat of the long rover & # 39; as he was ascending. The calculations were then compared to models of Mars landscape areas to ensure a correction.
The results were also compared to the concentration of mineral density from a Chemistry and Mineral device Curiosity, which identifies crystalline minerals in rock samples by a & using beam-X. This data helped to inform how well & # 39; the rocks are
There are many mountains in clay or canyons on Mars, but there is little to deal with the Mount Sharp scale. Scientists are still unsure how the mountain grows inside Gale Crater. One thought that the pit was once filled with sediment. Most of it is still a matter of debate, but the idea is that many millions of years of wind and last erosion are in fact; excavating the mountain.
If the crack was filled to its meaning, all that material should be pushed down, or blended, the fragments of fine sediment by the side. But the new paper states that lower Sharp layers are made up of just half a mile miles (1 to 2km) – much less than the pit was completely filled.
"There are still many questions about how Mount Sharp has been developed, but this paper puts an important part to the riddle," said author, Ashwin Vasavada, a scientific research project at NASA Jet Propulsion Laboratory. JPL manages the Mars Science Archive mission that is Curiosity as part of.
"I am delighted that creative scientists and engineers are still getting innovative ways to make new scientific discoveries with the rover," he says.
Lewis says Mars has enough secret over Ben Sharp. Landscape is similar to Earth, but it is surrounded more by wind and wind to blow than with water. Their sisters are flattened brothers, at the same time familiar and completely different.
"For me, Mars is an unbonned valley of the Earth," said Lewis. "It's like this but it was shaped by different processes. It's a so unnatural feeling of our earthly knowledge."
