All the Expert Researchers have used non-science
engineering data from NASA's Curiosity rover to find Mars rocks less compacted and Mars rocks more porous than expected, a/c to researchers. "Working from the rocks' mineral abundances as determined by the Chemistry and Mineralogy instrument, we estimated a grain density of 2,810 kg per cubic meter" "However, the bulk density that came out of our study is a high less, 1,680 kg per cubic meter". Curiosity landed near Mount Sharp in the Gale Crater on Mars in August 2012 and reached the base of the mountain in 2014. The team took out the engineering data from the first five years of the mission and used it to measure the gravitational tug of Mars at more than 700 points along the rover's track...
