Mars is Surprisingly Volcanically Active

Like many that grew up watching the skies, I have been captivated by the planets. Mars is no exception, with its striking red colour, polar caps and mysterious dark features. Many of the surface features have been driven by ancient volcanic activity but whether any geological activity moulds the terrain today is still subject to scientific debate. A recent study however has revealed that Mars is surprisingly active..even today!

This is Probably the Last Picture we’ll see From InSight on Mars

It’s almost time to say goodbye to another Martian friend. Plenty of missions to the Red Planet have gone silent for the last time, some after many successful years of data collection and some after a brief free-fall as a fireball. We will soon add another Martian explorer to that ever-growing list – InSight might have sent its final image home.

Despite its draining power, NASA’s InSight Mars lander is determined to squeeze as much science as it can until the very last moment

Its solar panels are caked with dust and the batteries are running out of juice, but NASA’s InSight Mars lander continues to soldier forth collecting more science about the Red Planet until its very last beep. To conserve energy, InSight was projected to shut down its seismometer—its last operational science instrument—by the end of June, hoping to survive on its remaining power until December. The seismometer has been the key instrument designed to measure marsquakes, which it has been recording since it touched down on Mars in 2018, and recently recorded a 5.0-magnitude quake, the biggest yet.

This is the Last Selfie InSight Will Ever Take

Few things in life captivate us more than looking at images from other planets, no matter how dull these images might seem. This is especially true for Mars, as it’s where we’ve sent the most robots to explore its cold and dry surface. The very first image from the surface of Mars in July 1976 was nothing more than the Viking 1 lander’s footpad and some rocks, but no one cared about these mundane details because we were looking at an image from Mars. We were looking at the surface of another world for the first time in human history, and not only were we captivated by it, but we wanted more.

InSight is Losing Power, it Probably Will be Shut Down in a Few Months

The InSight Mars lander will cease science operations sometime in the next few months due to a decreasing power supply, mission managers said at a news conference on May 17. Martian dust covering the solar panels has reduced the amount of power to roughly 500 watt-hours per Mars day or sol. When InSight landed in November of 2018, the solar panels produced around 5,000 watt-hours each sol.

“At the end of the calendar year, we do anticipate having to conclude all InSight operations,” said Kathya Zamora Garcia, InSight’s deputy project manager said at the briefing, “not because we want to turn it off but unfortunately we don’t have the energy to run it.”

NASA’s InSight Experiences its Most Powerful Marsquake so far: Magnitude 4.2, Lasting 90 Minutes

This selfie of NASA’s InSight lander is a mosaic made up of 14 images taken on March 15 and April 11 – the 106th and 133rd Martian days, or sols, of the mission – by the spacecraft Instrument Deployment Camera located on its robotic arm. Credit: NASA/JPL-Caltech

NASA’s InSight lander has detected one of the most powerful and longest-lasting quakes on the Red Planet since the start of its mission. The big marsquake happened on Sept. 18 on Earth, which happened to coincide with InSight’s 1,000th Martian day, or sol since it landed on Mars.

The temblor is estimated to be about a magnitude 4.2 and shook for an unthinkable hour-and-a-half! For comparison, on Earth, most quakes last for just a few seconds, although two (one in 1960 and another in 2004) lasted for about 10 minutes. Scientists are still studying the data collected on this marsquake to determine why (and how) it endured for such a long time.

Volcanoes on Mars Might Still be Active

Back in March, NASA’s InSight lander detected two large quakes from a geologically active region of Mars called the Cerberus Fossae. Now, using imagery from the Mars Reconnaissance Orbiter, which circles the red planet at an altitude of about 300km, researchers have discovered that the Cerberus Fossae region holds the most recent evidence of volcanic activity ever seen on Mars.

InSight Detects Two Significant Quakes from the Cerberus Fossae Region on Mars

NASA’s InSight lander felt the distant rumble of two major ‘marsquakes’ in March, originating from a region near the Martian equator known as the Cerberus Fossae. Registering magnitudes of 3.1 and 3.3 on March 7th and March 18th respectively, the quakes cement the Cerberus Fossae’s reputation as one of the most geologically active places on the Red Planet today. A pair of similarly strong marsquakes rocked the same region back in 2019.

Finally! Mars InSight’s Mole is Now Underground

It looks like the InSight Lander’s Mole instrument is making some progress. After months of perseverance, the team operating the instrument has succeeded in getting the Mole at least some distance into the ground.

That’s a victory in itself, considering all the setbacks there’ve been. But it’s too soon to celebrate: there’s quite a ways to go before the Mole can deliver any science.

InSight Just Put a Windshield Over its Seismometer

NASA’s InSight lander arrived on Mars on November 26th, 2018. Since then, it’s been busying itself studying its landing spot, and taking its time to carefully place its instruments. It spent several weeks testing the seismometer and adjusting it, and now it’s placed the domed, protective shield over the instrument.
