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 team of researchers from the ASU (Arizona State University), as well as a graduate student, measured the density of rock layers in the 154-km-wide Gale Crater on Mars,
A/C to Xinhua news agency reported.

The discovery gives scientists a novel technique to use in the future as the rover continues its trek across the crater and up Mount Sharp, up to the 4.8-km-high mountain in its center, according to All the Experts.
“What we were able to do is measure the bulk density of the material in Gale Crater”
Said Travis Gabriel, the graduate student at the ASU (Arizona State University)…
“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”
A/C to Travis Gabriel…
The much lower figure shows that the rocks have a reduced density most likely resulting from the rocks being more porous,
A/c to the research published in the journal Science.
Planetary scientists have long debated the origin of Mount Sharp. The new findings suggest Mount Sharp’s lower layers have been compacted by only one to two km of material, much less than if the crater had been completely filled.
Curiosity landed near Mount Sharp in the Gale Crater on Mars on 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.
As Curiosity has been ascending Mount Sharp, the mountain began to tug on it, as well—but not as much as scientists expected.
“The lower levels of Mount Sharp are surprisingly porous”
A/c To Kevin Lewis (Johns Hopkins University in the US).
“We know the bottom layers of the mountain were buried over time. That compacts them, making them denser”.
