NASA InSight Mars Lander

Insight R.I.P.?

On Dec. 18, 2022, NASA’s InSight did not respond to communications from Earth. The lander’s power has been declining for months, as expected, and it’s assumed InSight may have reached its end of operations. It’s unknown what prompted the change in its energy; the last time the mission contacted the spacecraft was on Dec. 15, 2022.

The mission will continue to try and contact InSight.

It will be sad if true for InSight, I would think that JPL would try to keep in contact to see if it was just a glitch in the communications at that time when they sent the signal. Though I would not be surprised at the loss of signal from InSight as the lander was loosing power gradually since the summer.

Although its mission ended in December, data from NASA’s InSight lander is allowing scientists to continue making new discoveries about Mars.

In fact, one team of scientists recently discovered that Mars’ rotational speed is accelerating ⬇️

Highly interesting Flyaway. Mars rotation speeding up. I wonder what the cause is? Perhaps it is the core not being solidified as it was once thought to be and that is having an effect on the rotation.
The strongest-ever quake to violently shake Mars arose not because of a crashing asteroidbut rather the tectonic forces within the planet itself, scientists reported on Tuesday (Oct. 17). The new findings show the Red Planet is more seismically active than previously thought.
On May 4, 2022, NASA's now-retired InSight lander recorded a magnitude 4.7 quake, five times stronger than the previous record holder of magnitude 4.2 that InSight measured in 2021. Unlike most marsquakes that cease within an hour, the reverberations from the May 2022 quake continued for a record six hours, marking the strongest and longest quake ever recorded on another planet.

The core of Mars can look bigger than it actually is because of a previously unknown layer of molten rock surrounding it, scientists suggest with a pair of new studies.

Since the 2021 studies appeared, InSight detected more Martian seismic waves, produced by a meteorite impact on Mars far away from the lander. "The impact produced a lot of energy, generating seismic waves that traversed the core of Mars," Khan said. "Up until then, we didn't have any of those to examine. They allowed us to gain a completely new picture of the interior of Mars, especially deep structures that we couldn't illuminate before."

Two new studies now estimate the center of Mars is about 2,050 to 2,080 miles (3,300 to 3,350 km) in diameter. All in all, the Martian core "is 30 percent smaller in volume than previous estimates," Henri Samuel, a planetary dynamicist at Paris Cité University in France, told

Scientists have calculated the rate of meteoroid impacts on Mars using seismic measurements from NASA’s retired InSight lander. Two new studies estimate much higher impact rates than were previously derived from orbital spacecraft.
