Brad Pitt w laboratorium NASA

THIS PICTURE: The engineering model of NASA's InSight lander ??" a replica used for test purposes ??" took an image of the actor Brad Pitt at NASA's Jet Propulsion Laboratory in Pasadena, California, on Sept. 6, 2019. Taken by the instrument deployment camera on the replica's robotic arm in the Mars-like environment of JPL???s In-Situ Instrument Laboratory, the picture has been white-balanced to remove the orange-red tint of the Mars lights in the room. Pitt visited JPL to learn about real space technology after filming his space-themed movie "Ad Astra." ... STORY CAPTION (FULL WORDS AVAIL: INFO@COVERMG.COM): Three papers published Thursday (22 July) share new details on the crust, mantle, and molten core of Mars Before NASA???s InSight spacecraft touched down on Mars in 2018, the rovers and orbiters studying the Red Planet concentrated on its surface. The stationary lander???s seismometer has changed that, revealing details about the planet???s deep interior for the first time. Three papers based on the seismometer???s data were published in Science, providing details on the depth and composition of Mars??? crust, mantle, and core, including confirmation that the planet???s center is molten. Earth???s outer core is molten, while its inner core is solid; scientists will continue to use InSight???s data to determine whether the same holds true for Mars. ??sWhen 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. ??sThis represents the culmination of all the work and worry over the past decade.??? InSight???s seismometer, called the Seismic Experiment for Interior Structure (SEIS), has recorded 733 distinct marsquakes. About 35 of those ??" all between magnitudes 3.0 and 4.0 ??" provided the data for the three paper
