NASA's InSight Lander leans in to better hear the subterranean tremors of Mars, and the Robotics Explorer has brought its seismometer to the surface at the end of last month and is now approaching "for a better connection with Mars." Before and after pictures show their instrument at its lowest position,
days before, InSight leveled its seismometer and adjusted the internal sensors before lowering the ground.
"It's always good to be centered and balanced," says InSight Twitter .
The Lander  Now, NASA says the instruments for the best possible hearing were still positioned at the lowest point.
"My seismometer has been depressed at its lowest level to make a better connection to Mars & # 39 ;, the InSight Twitter account wrote this week. "Weak signals are easier to hear when you keep your ear near the ground."
The InSight lander launched its first instrument on the surface of Mars in late December.
Images of the lander show the seismometer on the ground after being lifted to the surface by the lander's robotic arm.
It will pick up the waves that travel through the planet's inner structure and may help explain mysterious "Marsquakes" that scientists believe regularly occur.
At the time, NASA said the Lander War was flawless and ahead of schedule.
New images of the lander show the seismometer on the ground after being lifted to the surface by the lander's robotic arm. It will record the waves that travel through the planet's internal structure and could help explain mysterious "Marsquakes" that scientists believe regularly occur. This was the first time a scientific instrument was put on the surface of another planet.
WHAT WILL THE SEISMOMETER DO?
The seismometer gives scientists an insight into the Martian interior by examining ground movements – also called Marsquakes.
Each Marsquake acts as a kind of flash lamp that illuminates the structure of the planet's interior.
By analyzing how seismic waves travel through the layers of the planet, scientists can derive the depth and composition of these layers.
"InSight's schedule of activities on Mars has gone better than we had hoped," said Tom Hoffman, Project Manager of InSight, at NASA's Jet Propulsion Laboratory in California Pasadena works.
"Getting the seismometer safe on the ground is a great Christmas present."
The InSight team has been working on Mars since landing on Mars on November 26. Use the Seismometer (also known as Inner Structure or SEIS seismic experiment) and the Heat Probe (also as a probe for heat flow and physical properties (HP3), the engineers first had to check the robotic arm that lifts and places them. The InSight instruments on the Martian surface worked flawlessly.
The engineers tested the commands for the lander and made sure that a model in the test rig at JPL used the instruments exactly as intended.
The scientists also had to analyze images of the Martian land around the lander to find out where the instruments could best be used.
On Tuesday, December 18, InSight engineers sent orders to the spaceship.
On Wednesday, Dec. 19, the seismometer was gently lowered to the ground just in front of the lander, approximately as far as the arm can reach it (5,367 feet or 1,636 meters).
"Seismometer deployment is as important as the landing of InSight on Mars," said Bruce Banerdt, Investigator of InSight, which is based at JPL.
"The seismometer is the highest priority instrument at InSight: we need it to reach three quarters of our scientific goals."

The seismometer allows scientists to look into the Martian interior by studying ground motion – also known as Marsquakes.
"When the seismometer is on the ground, it's like holding a telephone to your ear," said Philippe Lognonné, chief investigator at the SEIS of the Paris-based Institute of Physique du Globe (IPGP) and Paris Diderot University.
& # 39; We are thrilled that we are now in the best position to hear all seismic waves from below the surface of Mars and from its deep interior. & # 39;
In the coming days, the InSight team will be working on leveling the seismometer, sitting on a 2 to 3 degree inclined ground.
The first seismometer science data should begin to flow back to Earth after the seismometer is in the correct position.

With three key instruments, the InSight lander can "catch the pulse" of the red planet:
Seismometer : The InSight Lander carries a Seismometer SEIS that hears the pulse of Mars.
The seismometer detects the waves that travel through the inner structure of a planet.
The study of seismic waves tells us what the waves could do.
On Mars, scientists suspect that the perpetrators may be Marsquakes or meteorites hitting the surface.
Heat Probe: InSight's HP3 heat flow probe drills deeper than any other blades, drills, or probes on Mars.
It is investigated how much heat still flows from Mars.
Radio Antennas: Like Earth, Mars wobbles as it turns around its axis.
To study this, two radio antennas that are part of the RISE instrument closely track the lander's position.
This helps scientists to test the planet's reflections and tells them how the deep internal structure affects the planet's motion around the sun.
"We look forward to drinking some champagne We are starting to collect data from the InSight seismometer on site," added Banerdt.
"I have a bottle ready for the occasion."
Meanwhile, the Rotation and Interior Structure Experiment (RISE), which does not have its own separate instrument, has already used the InSight radio link with Earth to collect preliminary data on the planet's core.
There is not enough time for scientists to deduce what they want to know – scientists estimate that they will have some results from about a year on.

NASA has recently discovered its Mars Reconnaissance Orbiter thanks to a powerful camera and the exact landing area of its new Mars explorer.
While the space agency knew that InSight had landed on the red planet within a 130 km ellipse, it was not possible to determine exactly where it landed in that region.

NASA has finally found the location of the new Mars explorer, thanks to a powerful camera on the Mars Reconnaissance Orbiter. While the space agency knew that InSight had landed on the red planet within a 130-kilometer ellipse, it was not possible to determine exactly where it landed in that region.
In the pictures published today by NASA InSight and its parts appear on a reddish-white landscape as bright teal cardinal points.
In reality, this is just a trick of the light.
"The light reflected from their surfaces causes the paint to be saturated," NASA explains
"The soil around the lander appears dark, as it was blasted off its back slides as it descended. Look carefully for a butterfly shape and you can see the lander's solar panels on both sides. & # 39;
A few days ago, NASA's new InSight Lander snapped its first selfie from the Red Planet, so the mission team (and the rest of the world) has a good view of its solar panels and their deck on which it is now located.
InSight also returned the first full view of the 14 x 7-foot site, which will soon serve as a "work area".
In images released today by NASA, InSight and its parts appear as bright spots on rust-colored landscapes. In reality, this is just a trick of the light.
A series of images taken with MRO's HiRISE camera this week has confirmed that Lander (red dot), heat shield and parachute are all seated at a height of less than 300 meters on a lava plane called Elysium Planitia. Previously, the space agency only knew that it had landed within an 81-mile ellipse (blue)
. Each of the new images is a mosaic of several stitches collected together.
While the selfie, captured by the robotic arm, consists of eleven images, the workspace comprises 52 individual photos.
This allows scientists to study the environment well before InSight starts dropping its instruments and digging into the ground.
"The near – The absence of rocks, hills and holes makes the instrument extremely safe for our instruments," said Bruce Banerdt, chief executive of InSight, NASA's Jet Propulsion Laboratory.
"This could be It would look like a fairly simple ground if it were not so Not on Mars, but we're glad to see that. "
NASA has confirmed the landing sites for InSight, its parachute and other components thanks to new images of the Mars Reconnaissance Orbiter
InSight previously sent the first full view of the 14 x 7 foot stretch of land that will soon serve as his working area displayed in the Blue Crescent. The team says it looks "extremely safe." The parachute, back shell and heat shield all landed at a distance of less than 200 meters.
Even Mars robots seem to be a tourist like tourists. NASA's new InSight lander has snapped its first selfie from the Red Planet so that the mission team (and the rest of the world) has a good look at its solar panels and deck after settling
last week was. InSight has sent back the first of his observations – including a light clip streaming over the surface and images of Martian winds.
All this happens when the lander and the team behind his operations prepare to start working in the US The next few months.
At that moment InSight is taking steps for the baby.
The lander leaned this week with his six-foot-long arm and took pictures of the area immediately ahead of him.
"By, I gently swing my arm out in front of me and look at the floor in front of me, where I'll do my job," tweeted the Nasa InSight account.

The Interior Interior (SEIS) data collected by InSight's Seismic Experiment for will eventually be used to suppress background noise in the months before it is moved to the ground, as Marsquakes are detected.
Just a few days earlier, NASA discovered that the InSight Lander had caught the sound of a Stingray Devil in the early days of the Red Planet.
According to the Space Agency, it's the first time we've heard the Martian winds.
The Deep Rumble Detec The blowing speeds measured by InSight sensors are expected to blow from 5 to 7 meters per second from northwest to southeast – and the recordings are in the human ear.
NASA says that the sounds recorded on December 1 were observed with dust devil strips in the landing area.
The vibrations were recorded at a very low pitch, although those with sharp ears can hear this with headphones or subwoofers.
To make things clearer, NASA raised the pitch by two octaves and audible on laptops and mobile devices.
The space agency shared a series of high-resolution photos taken this week. InSight will soon capture pictures of the terrain just in front of it so that the team can select the best location to drill down. The solar panel that can power the machine is shown
While InSight did not intend to record the winds of Mars, the team says that this type of data collection goes along with the area.
The lander detected wind vibrations with two of his sensors: one for measuring air pressure and one with a seismometer on the deck.
"Recording this audio was an unplanned pleasure," says Bruce Banerdt, InSight chief investigator at NASA's Jet Propulsion Lab.
However, our goal is to measure the movement on Mars. Of course, this also includes movements caused by sound waves. "
According to the InSight team, the two different instruments have picked up the noise in different ways.
While the Auxiliary Payload Sensor's air pressure sensor was recording the vibrations directly, the seismometer picked up vibrations caused by the wind passing over the lander's solar panels.
InSight's Seismic Experiment for Interior Structure (SEIS) is ultimately used to eliminate background noise in the detection of Marsquakes in the pre-ground months.
With its short-wave (SP) silicon sensors, vibrations can be detected at frequencies up to high. NASA says, "The InSight Lander behaves like a giant ear," said Tom Pike, member of the InSight Science Team and Sensor of the InSight Imperial College London.
"The solar panels on the sides of the lander react to wind pressure fluctuations.
" It's as if InSight hooks its ears and hears the Martian wind beating on it. If we look at the direction of the land oscillations emanating from the solar panels, it corresponds to the expected wind direction at our landing site. "
InSight landed in a region known as Elysium Planitia. The location of the map is not far from the landing site of Curiosity Mission 2012, the last NASA spacecraft to land on Mars.
NASA's InSight Lander has finally removed the camera The camera's lens cover allows the robot explorer to make the clearest images of his new house so far
The team has both an unprocessed audio sample of the seismometer Recording as well as a second version released, which was raised by two octaves easier to hear.
For the latter, the APSS sample has been accelerated by a factor of 100.
According to experts, the sound source is pretty straightforward; Vibration detected by the instruments is similar to the changes in air pressure that you hear when a flag swirls in the wind.
"That's literally the noise – changes in air pressure," said Don Banfield InSight, scientific director of APSS at Cornell University in Ithaca, New York.
"You hear that when you talk to someone in the other room."
