Spaceflight Insider Theresa Cross August 2nd, 2021 NASA’s InSight lander deployed its Wind and Thermal Shield on sol 66 — Feb. 2, 2019. The shield covers the lander’s seismometer, which was set down onto the Martian surface on Dec. 19, 2018. Over 2.5 years later, data from the seismometer have shown Mars’ center to be molten. Credit: NASA/JPL-Caltech Using data collected by NASA’s Mars InSight lander, which has been on the red planet since 2018, researchers have confirmed the planet’s center to be molten. This comes from three papers published in “Science” on July 22, 2021, th...

What InSight found out was that Mars has a rather thin and layered crust. Under that lies a thick mantle and that literal hell of a core. The SEIS (Seismic Experiment for Interior Structure) data went into such depth that researchers actually published three studies in Science — one each for the crust, mantle and core — and a fourth that goes into the overall composition of Martian innards. “Seismic waves are a great tool to tell you about the interior of a planet,” researcher Bridgitte Knapmeyer-Enddrun, who led the crust study, tells SYFY WIRE. “They travel through the planet an...

Thu 29 Jul 2021 01.00 EDT Nasa’s InSight lander has revealed the depth of Mars’s crust and the size of its central core by using data from dozens of marsquakes captured since the probe landed in 2018. The Seismic Experiment for Interior Structure (SEIS) is a dome-shaped instrument that sits on the surface of Mars and can pick up seismic events hundreds or even thousands of miles away. Since its deployment, the mission has recorded 733 distinct marsquakes, about 35 of which were used for the current work. All quakes registered between magnitudes 3 and 4. Their analysis shows that the...

NASA's InSight Mars Lander Gets a Power Boost The spacecraft successfully cleared some dust off its solar panels, helping to raise its energy and delay when it will need to switch off its science instruments. The team behind NASA’s InSight Mars lander has come up with an innovative way to boost the spacecraft’s energy at a time when its power levels have been falling. The lander’s robotic arm trickled sand near one solar panel, helping the wind to carry off some of the panel’s dust. The result was a gain of about 30 watt-hours of energy per sol, or Martian day.
