The first samples collected from NASA’s mission to Mars were published on Thursday , revealing new details on the planet’s outer surface and core previously known to scientists.
“When we first started putting together the concept of the mission more than a decade ago, the information in these papers is what we hoped to get at the end,” said InSight’s principal investigator Bruce Banerdt of NASA’s Jet Propulsion Laboratory in Southern California, which leads the mission. “This represents the culmination of all the work and worry over the past decade.”
Using seismic data helped researchers gauge the structure of each layer of Mars based on how fast the seismic waves move when traveling through different materials of a planet, such as rocks versus liquids.
New findings using data from our @NASAInsight lander's seismometer reveal, for the first time, details about the deep interior of Mars. What scientists learned about the depth and composition of the Red Planet's crust, mantle, and molten core: https://t.co/jF1tk7vtUq pic.twitter.com/bq5K9H74dT
