Researchers have developed a new Gravity Map of Mars

Researchers have developed a new Gravity Map of Mars
22 March 2016 Current Affairs: Researchers have developed a new map of Mars’ gravity with three NASA spacecraft that is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet.“Gravity maps allow us to see inside a planet, just as a doctor uses an X-ray to see inside a patient,” said Antonio Genova from Massachusetts Institute of Technology (MIT).The new gravity map will be helpful for future Mars exploration, because better knowledge of the planet’s gravity anomalies helps mission controllers insert spacecraft more precisely into orbit about Mars.Furthermore, the improved resolution of our gravity map will help us understand the still-mysterious formation of specific regions of the planetThe improved resolution of the new gravity map suggests a new explanation for how some features formed across the boundary that divides the relatively smooth northern lowlands from heavily cratered southern highlands.Also, the team confirmed that Mars has a liquid outer core of molten rock by analysing tides in the Martian crust and mantle caused by the gravitational pull of the sun and the two moons of Mars.Finally, by observing how Mars’ gravity changed over 11 years – the period of an entire cycle of solar activity – the team inferred the massive amount of carbon dioxide that freezes out of the atmosphere onto a Martian polar ice cap when it experiences winter.hey also observed how that mass moves between the south pole and the north pole with the change of season in each hemisphere.The gravity field was recovered using about 16 years of data that were continuously collected in orbit around Mars.The map was derived using data collected by NASA’s Deep Space Network from three NASA spacecraft in orbit around Mars: Mars Global Surveyor (MGS), Mars Odyssey (ODY), and the Mars Reconnaissance Orbiter (MRO).The better resolution of the new map helps interpret how the crust of the planet changed over Mars’ history in many regions.
