Pasadena, CA – NASA’s InSight lander has detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae – the same place where two strong quakes were seen earlier in the mission.
The new quakes have magnitudes of 3.3 and 3.1; the previous quakes were magnitude 3.6 and 3.5. InSight has recorded over 500 quakes to date, but because of their clear signals, these are four of the best quake records for probing the interior of the planet.
Pasadena, CA – NASA’s InSight spacecraft touched down November 26th, 2018, on Mars to study the planet’s deep interior.
A little more than one Martian year later, the stationary lander has detected more than 480 quakes and collected the most comprehensive weather data of any surface mission sent to Mars. InSight’s probe, which has struggled to dig underground to take the planet’s temperature, has made progress, too.
There was a time when the surfaces of Mars and Earth were very similar. Both were warm, wet, and shrouded in thick atmospheres.
Pasadena, CA – NASA’s InSight lander has been using its robotic arm to help the heat probe known as the “mole” burrow into Mars. The mission is providing the first look at the Red Planet’s deep interior to reveal details about the formation of Mars and, ultimately, all rocky planets, including Earth.
Akin to a 16-inch-long (40-centimeter-long) pile driver, the self-hammering mole has experienced difficulty getting into the Martian soil since February 2019. It’s mostly buried now, thanks to recent efforts to push down on the mole with the scoop on the end of the robotic arm.
Pasadena, CA – A new understanding of Mars is beginning to emerge, thanks to the first year of NASA’s InSight lander mission. Findings described in a set of six papers published today reveal a planet alive with quakes, dust devils and strange magnetic pulses.
Five of the papers were published in Nature. An additional paper in Nature Geoscience details the InSight spacecraft’s landing site, a shallow crater nicknamed “Homestead hollow” in a region called Elysium Planitia.
Pasadena, CA – Sue Smrekar really wants to go back to Venus. In her office at NASA’s Jet Propulsion Laboratory in Pasadena, California, the planetary scientist displays a 30-year-old image of Venus’ surface taken by the Magellan spacecraft, a reminder of how much time has passed since an American mission orbited the planet.
The image reveals a hellish landscape: a young surface with more volcanoes than any other body in the solar system, gigantic rifts, towering mountain belts and temperatures hot enough to melt lead.
Pasadena, CA – After making progress over the past several weeks digging into the surface of Mars, NASA’s InSight Lander’s mole has backed about halfway out of its hole this past weekend. Preliminary assessments point to unusual soil conditions on the Red Planet. The international mission team is developing the next steps to get it buried again.
A scoop on the end of the arm has been used in recent weeks to “pin” the mole against the wall of its hole, providing friction it needs to dig. The next step is determining how safe it is to move InSight’s robotic arm away from the mole to better assess the situation. The team continues to look at the data and will formulate a plan in the next few days.
Pasadena, CA – Put an ear to the ground on Mars and you’ll be rewarded with a symphony of sounds. Granted, you’ll need superhuman hearing, but NASA’s InSight lander comes equipped with a very special “ear.”
The spacecraft’s exquisitely sensitive seismometer, called the Seismic Experiment for Interior Structure (SEIS), can pick up vibrations as subtle as a breeze. The instrument was provided by the French space agency, Centre National d’Études Spatiales (CNES), and its partners.
Pasadena, CA – A recent set of earthquakes shook up Southern California. But NASA says Earth isn’t the only place that experiences quakes: Both the Moon and Mars have them as well. NASA sent the first seismometer to the Moon 50 years ago, during the Apollo 11 mission; the agency’s InSight lander brought the first seismometer to Mars in late 2018, and it’s called the Seismic Experiment for Interior Structure (SEIS).
Provided by the French space agency, Centre National d’Études Spatiales (CNES), the seismometer detected its first marsquake on April 6th, 2019.
Pasadena, CA – NASA InSight’s heat probe has been unable to dig very far on the surface of Mars. Scientists and engineers have a new plan for getting the probe also known as the “mole,” digging again on Mars. Part of an instrument called the Heat Flow and Physical Properties Package (HP3), the mole is a self-hammering spike designed to dig as much as 16 feet (5 meters) below the surface and record temperature.
But the mole hasn’t been able to dig deeper than about 12 inches (30 centimeters) below the Martian surface since February 28th, 2019.

Pasadena, CA – No matter how cold your winter has been, it’s probably not as chilly as Mars. Check for yourself: Starting today, the public can get a daily weather report from NASA’s InSight lander.
This public tool includes stats on temperature, wind and air pressure recorded by InSight. Sunday’s weather was typical for the lander’s location during late northern winter: a high of 2 degrees Fahrenheit (-17 degrees Celsius) and low of -138 degrees Fahrenheit (-95 degrees Celsius), with a top wind speed of 37.8 mph (16.9 m/s) in a southwest direction.
