Safely on Mars, InSight unfolds its arrays and snaps some pics

After safely landing on Mars following its nearly seven month journey, NASA has released the first pictures taken by its InSight spacecraft, which has opened it solar arrays to charge batteries.




The $993 million lander, which landed on Monday and appears to be in good shape, will soon begin unfolding its robotic arm and deploying its quake-sensors on the Martian surface.

NASA engineers are planning to begin work with its robotic arm soon, but are proceeding with caution.

The arm has five mechanical fingers to help it lift out and place its two instruments on Martian soil in the coming few months.

"Slowly releasing all my pent-up tension, starting with loosening my grapple, as these before-and-after pics show," said the NASAInSight Twitter account.

"Until I'm ready to stretch my arm out, my camera angles will be the same."

InSight is equipped with two full-color cameras and has already sent back six shots since touching down.

The waist-high spacecraft will stay in place for the two-year duration of its mission.

NASA has not said anything about the condition of the other instruments on board, which include a French-made seismometer to study Marsquakes and a German self-hammering mole to measure heat's escape from the planet.

NASA did say its solar arrays have deployed, which is good news since the lander runs on solar energy.

In Paris, the French space agency CERN said everything seems fine for the moment, and that it is up to NASA to communicate with the SEIS quake-sensing instrument.

SAY CHEESE:


InSight's first job, just several minutes after landing, is to take a picture. Ground controllers want to see what they're up against. Big rocks or a hillside could interfere with the stationary lander's geology experiments. Once the red dust settles about 16 minutes after touchdown, the lander will spread its solar panels and settle in for its first long winter's nap at Mars.

NASA's Martian quake sensor InSight lands at slight angle
December 1, 2018

[Image: the993millio.jpg]
The $993 million InSight lander arrived at its target, a lava plain named Elysium Planitia, for a two-year mission aimed at better understanding how Earth's neighboring planet formed
NASA's unmanned Martian quake sensor, InSight, has landed at a slight angle on the Red Planet, and experts are hopeful the spacecraft will work as planned, the US space agency said Friday.




The $993 million lander arrived Monday at its target, a lava plain named Elysium Planitia, for a two-year mission aimed at better understanding how Earth's neighboring planet formed.

"The vehicle sits slightly tilted (about 4 degrees) in a shallow dust- and sand-filled impact crater known as a 'hollow,'" NASA said in a statement.

InSight was engineered to operate on a surface with an inclination up to 15 degrees.

Therefore, experts are hopeful that its two main instruments—a quake sensor and self-hammering mole to measure heat below the surface—will work as planned.

"We couldn't be happier," said InSight project manager Tom Hoffman of NASA's Jet Propulsion Laboratory.

"There are no landing pads or runways on Mars, so coming down in an area that is basically a large sandbox without any large rocks should make instrument deployment easier and provide a great place for our mole to start burrowing."

The first pictures from the lander show just a few rocks in the vicinity, more good news since touching down right near a rocky area would have made deployment of the solar arrays and instruments tricky.

Better images are expected in the coming days once InSight sheds the dust covers on its two cameras.

"We are looking forward to higher-definition pictures to confirm this preliminary assessment," said Bruce Banerdt, principal investigator of InSight at NASA.

"If these few images—with resolution-reducing dust covers on—are accurate, it bodes well for both instrument deployment and the mole penetration of our subsurface heat-flow experiment."

NASA's Mars InSight flexes its arm
December 7, 2018 by Andrew Good, NASA

New images from NASA's Mars InSight lander show its robotic arm is ready to do some lifting.




With a reach of nearly 6 feet (2 meters), the arm will be used to pick up science instruments from the lander's deck, gently setting them on the Martian surface at Elysium Planitia, the lava plain where InSight touched down on Nov. 26.

But first, the arm will use its Instrument Deployment Camera, located on its elbow, to take photos of the terrain in front of the lander. These images will help mission team members determine where to set InSight's seismometer and heat flow probe - the only instruments ever to be robotically placed on the surface of another planet.

"Today we can see the first glimpses of our workspace," said Bruce Banerdt, the mission's principal investigator at NASA's Jet Propulsion Laboratory in Pasadena, California. "By early next week, we'll be imaging it in finer detail and creating a full mosaic."

Another camera, called the Instrument Context Camera, is located under the lander's deck. It will also offer views of the workspace, though the view won't be as pretty.

"We had a protective cover on the Instrument Context Camera, but somehow dust still managed to get onto the lens," said Tom Hoffman of JPL, InSight's project manager. "While this is unfortunate, it will not affect the role of the camera, which is to take images of the area in front of the lander where our instruments will eventually be placed."

Placement is critical, and the team is proceeding with caution. Two to three months could go by before the instruments have been situated and calibrated.

Over the past week and a half, mission engineers have been testing those instruments and spacecraft systems, ensuring they're in working order. A couple instruments are even recording data: a drop in air pressure, possibly caused by a passing dust devil, was detected by the pressure sensor. This, along with a magnetometer and a set of wind and temperature sensors, are part of a package called the Auxiliary Payload Sensor Subsystem, which will collect meteorological data.



More images from InSight's arm were scheduled to come down this past weekend. However, imaging was momentarily interrupted, resuming the following day. During the first few weeks in its new home, InSight has been instructed to be extra careful, so anything unexpected will trigger what's called a fault. Considered routine, it causes the spacecraft to stop what it is doing and ask for help from operators on the ground.

Image Credit: NASA/JPL-Caltech"We did extensive testing on Earth. But we know that everything is a little different for the lander on Mars, so faults are not unusual," Hoffman said. "They can delay operations, but we're not in a rush. We want to be sure that each operation that we perform on Mars is safe, so we set our safety monitors to be fairly sensitive initially."


Spacecraft engineers had already factored extra time into their estimates for instrument deployment to account for likely delays caused by faults. The mission's primary mission is scheduled for two Earth years, or one Mars year - plenty of time to gather data from the Red Planet's surface.

InSight lander 'hears' Martian winds

December 7, 2018 by Dwayne Brown, NASA

NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport InSight lander, which touched down on Mars just 10 days ago, has provided the first ever "sounds" of Martian winds on the Red Planet. A media teleconference about these sounds will be held today at 12:30 p.m. EST (9:30 a.m. PST).




InSight sensors captured a haunting low rumble caused by vibrations from the wind, estimated to be blowing between 10 to 15 mph (5 to 7 meters a second) on Dec. 1, from northwest to southeast. The winds were consistent with the direction of dust devil streaks in the landing area, which were observed from orbit.

"Capturing this audio was an unplanned treat," said Bruce Banerdt, InSight principal investigator at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. "But one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves."

Two very sensitive sensors on the spacecraft detected these wind vibrations: an air pressure sensor inside the lander and a seismometer sitting on the lander's deck, awaiting deployment by InSight's robotic arm. The two instruments recorded the wind noise in different ways. The air pressure sensor, part of the Auxiliary Payload Sensor Subsystem (APSS), which will collect meteorological data, recorded these air vibrations directly. The seismometer recorded lander vibrations caused by the wind moving over the spacecraft's solar panels, which are each 7 feet (2.2 meters) in diameter and stick out from the sides of the lander like a giant pair of ears.



This is the only phase of the mission during which the seismometer, called the Seismic Experiment for Interior Structure SEIS, will be capable of detecting vibrations generated directly by the lander. In a few weeks, it will be placed on the Martian surface by InSight's robotic arm, then covered by a domed shield to protect it from wind and temperature changes. It still will detect the lander's movement, though channeled through the Martian surface. For now, it's recording vibrational data that scientists later will be able to use to cancel out noise from the lander when SEIS is on the surface, allowing them to detect better actual marsquakes.

When earthquakes occur on Earth, their vibrations, which bounce around inside our planet, make it "ring" similar to how a bell creates sound. InSight will see if tremors, or marsquakes, have a similar effect on Mars. SEIS will detect these vibrations that will tell us about the Red Planet's deep interior. Scientists hope this will lead to new information on the formation of the planets in our solar system, perhaps even of our own planet.



SEIS, France's Centre National d'Études Spatiales (CNES), includes two sets of seismometers. Those contributed by the French will be used once SEIS is deployed from the deck of the lander. But SEIS also includes short period (SP) silicon sensors developed by Imperial College London with electronics from Oxford University in the United Kingdom. These sensors can work while on the deck of the lander and are capable of detecting vibrations up to frequencies of nearly 50 hertz, at the lower range of human hearing.




"The InSight lander acts like a giant ear," said Tom Pike, InSight science team member and sensor designer at Imperial College London. "The solar panels on the lander's sides respond to pressure fluctuations of the wind. It's like InSight is cupping its ears and hearing the Mars wind beating on it. When we looked at the direction of the lander vibrations coming from the solar panels, it matches the expected wind direction at our landing site."


Pike compared the effect to a flag in the wind. As a flag breaks up the wind, it creates oscillations in air pressure that the human ear perceives as flapping. Separately, APSS records changes in pressure directly from the thin Martian air.

"That's literally what sound is—changes in air pressure," said Don Banfield InSight's science lead for APSS from Cornell University in Ithaca, New York. "You hear that whenever you speak to someone across the room."

Unlike the vibrations recorded by the short period sensors, audio from APSS is about 10 hertz, below the range of human hearing.

The raw audio sample from the seismometer was released unaltered; a second version was raised two octaves to be more perceptible to the human ear—especially when heard through laptop or mobile speakers. The second audio sample from APSS was sped up by a factor of 100, which shifted it up in frequency.

An even clearer sound from Mars is yet to come. In just a couple years, NASA's Mars 2020 rover is scheduled to land with two microphones on board. The first, provided by JPL, is included specifically to record, for the first time, the sound of a Mars landing. The second is part of the SuperCam and will be able to detect the sound of the instrument's laser as it zaps different materials. This will help identify these materials based on the change in sound frequency.

InSight places first instrument on Mars
December 20, 2018, Jet Propulsion Laboratory

NASA's InSight lander has deployed its first instrument onto the surface of Mars, completing a major mission milestone. New images from the lander show the seismometer on the ground, its copper-colored covering faintly illuminated in the Martian dusk. It looks as if all is calm and all is bright for InSight, heading into the end of the year.




"InSight's timetable of activities on Mars has gone better than we hoped," said InSight Project Manager Tom Hoffman, who is based at NASA's Jet Propulsion Laboratory in Pasadena, California. "Getting the seismometer safely on the ground is an awesome Christmas present."

The InSight team has been working carefully toward deploying its two dedicated science instruments onto Martian soil since landing on Mars on Nov. 26. Meanwhile, the Rotation and Interior Structure Experiment (RISE), which does not have its own separate instrument, has already begun using InSight's radio connection with Earth to collect preliminary data on the planet's core. Not enough time has elapsed for scientists to deduce what they want to know—scientists estimate they might have some results starting in about a year.

To deploy the seismometer (also known as the Seismic Experiment for Interior Structure, or SEIS) and the heat probe (also known as the Heat Flow and Physical Properties Probe, or HP3), engineers first had to verify the robotic arm that picks up and places InSight's instruments onto the Martian surface was working properly. Engineers tested the commands for the lander, making sure a model in the test bed at JPL deployed the instruments exactly as intended. Scientists also had to analyze images of the Martian terrain around the lander to figure out the best places to deploy the instruments.

On Tuesday, Dec. 18, InSight engineers sent up the commands to the spacecraft. On Wednesday, Dec. 19, the seismometer was gently placed onto the ground directly in front of the lander, about as far away as the arm can reach—5.367 feet, or 1.636 meters, away).

"Seismometer deployment is as important as landing InSight on Mars," said InSight Principal Investigator Bruce Banerdt, also based at JPL. "The seismometer is the highest-priority instrument on InSight: We need it in order to complete about three-quarters of our science objectives."

The seismometer allows scientists to peer into the Martian interior by studying ground motion—also known as marsquakes. Each marsquake acts as a kind of flashbulb that illuminates the structure of the planet's interior. By analyzing how seismic waves pass through the layers of the planet, scientists can deduce the depth and composition of these layers.



"Having the seismometer on the ground is like holding a phone up to your ear," said Philippe Lognonné, principal investigator of SEIS from Institut de Physique du Globe de Paris (IPGP) and Paris Diderot University. "We're thrilled that we're now in the best position to listen to all the seismic waves from below Mars' surface and from its deep interior."

In the coming days, the InSight team will work on leveling the seismometer, which is sitting on ground that is tilted 2 to 3 degrees. The first seismometer science data should begin to flow back to Earth after the seismometer is in the right position.

But engineers and scientists at JPL, the French national space agency Centre National d'Études Spatiales (CNES) and other institutions affiliated with the SEIS team will need several additional weeks to make sure the returned data are as clear as possible. For one thing, they will check and possibly adjust the seismometer's long, wire-lined tether to minimize noise that could travel along it to the seismometer. Then, in early January, engineers expect to command the robotic arm to place the Wind and Thermal Shield over the seismometer to stabilize the environment around the sensors.

Assuming that there are no unexpected issues, the InSight team plans to deploy the heat probe onto the Martian surface by late January. HP3 will be on the east side of the lander's work space, roughly the same distance away from the lander as the seismometer.

For now, though, the team is focusing on getting those first bits of seismic data (however noisy) back from the Martian surface.

"We look forward to popping some Champagne when we start to get data from InSight's seismometer on the ground," Banerdt added. "I have a bottle ready for the occasion."

InSight prepares to take Mars' temperature
February 13, 2019, Jet Propulsion Laboratory

[Image: insightprepa.jpg]

NASA's InSight lander has placed its second instrument on the Martian surface. New images confirm that the Heat Flow and Physical Properties Package, or HP3, was successfully deployed on Feb. 12 about 3 feet (1 meter) from InSight's seismometer, which the lander recently covered with a protective shield. HP3 measures heat moving through Mars' subsurface and can help scientists figure out how much energy it takes to build a rocky world.




Equipped with a self-hammering spike, mole, the instrument will burrow up to 16 feet (5 meters) below the surface, deeper than any previous mission to the Red Planet. For comparison, NASA's Viking 1 lander scooped 8.6 inches (22 centimeters) down. The agency's Phoenix lander, a cousin of InSight, scooped 7 inches (18 centimeters) down.

"We're looking forward to breaking some records on Mars," said HP3 Principal Investigator Tilman Spohn of the German Aerospace Center (DLR), which provided the heat probe for the InSight mission. "Within a few days, we'll finally break ground using a part of our instrument we call the mole."

HP3 looks a bit like an automobile jack but with a vertical metal tube up front to hold the 16-inch-long (40-centimeter-long) mole. A tether connects HP3's support structure to the lander, while a tether attached to the top of the mole features heat sensors to measure the temperature of the Martian subsurface. Meanwhile, heat sensors in the mole itself will measure the soil's thermal conductivity—how easily heat moves through the subsurface.

"Our probe is designed to measure heat coming from the inside of Mars," said InSight Deputy Principal Investigator Sue Smrekar of NASA's Jet Propulsion Laboratory in Pasadena, California. "That's why we want to get it belowground. Temperature changes on the surface, both from the seasons and the day-night cycle, could add 'noise' to our data."

The mole stops about every 20 inches (51 centimeters) to warm up for roughly four days; the sensors check how rapidly this happens, which tells scientists the conductivity of the soil. Between the careful burrowing action, the pauses and the time required for the science team to send commands to the instrument, more than a month will go by before the mole reaches its maximum depth. If the mole extends as far as it can go, the team will need only a few months of data to figure out Mars' internal temperature.

If the mole encounters a large rock before reaching at least 10 feet (3 meters) down, the team will need a full Martian year (two Earth years) to filter noise out of their data. This is one reason the team carefully selected a landing site with few rocks and why it spent weeks choosing where to place the instrument.

"We picked the ideal landing site, with almost no rocks at the surface," said JPL's Troy Hudson, a scientist and engineer who helped design HP3. "That gives us reason to believe there aren't many large rocks in the subsurface. But we have to wait and see what we'll encounter underground."

However deep it gets, there's no debating that the mole is a feat of engineering.

"That thing weighs less than a pair of shoes, uses less power than a Wi-Fi router and has to dig at least 10 feet [3 meters] on another planet," Hudson said. "It took so much work to get a version that could make tens of thousands of hammer strokes without tearing itself apart; some early versions failed before making it to 16 feet [5 meters], but the version we sent to Mars has proven its robustness time and again."

Good luck 'Mole'—experiment starts hammering into the Martian soil
by DLR German Aerospace Center

Credit: DLR German Aerospace Center
On 28 February 2019, 'Mole' fully automatically hammered its way into the Martian subsurface for the first time. In a first step, it penetrated to a depth between 18 and 50 centimetres into the Martian soil with 4000 hammer blows over a period of four hours. "On its way into the depths, the mole seems to have hit a stone, tilted about 15 degrees and pushed it aside or passed it," reports Tilman Spohn, Principal Investigator of the HP3 experiment. "The Mole then worked its way up against another stone at an advanced depth until the planned four-hour operating time of the first sequence expired. Tests on Earth showed that the rod-shaped penetrometer is able to push smaller stones to the side, which is very time-consuming.

After a cooling-off period, the researchers will command a second four-hour hammering sequence. In the following weeks, with further intervals, they want to reach a target depth of three to five metres on sufficiently porous ground. The Mole will pull a five-metre-long tether equipped with temperature sensors into the Martian soil behind it. The cable is equipped with 14 temperature sensors in order to measure the temperature distribution with depth and its change with time after reaching the target depth and thus the heat flow from the interior of Mars.
The rod-shaped penetrometer uses a fully automatic, electrically powered hammer mechanism to drive itself into the subsurface. A rotating worm gear repeatedly stretches the main spring, which then produces a hammer blow. A second spring absorbs the recoil. "You can imagine the Mars Mole functioning like a large nail that has a built-in hammer," says Torben Wippermann from the DLR Institute of Space Systems, explaining the technology.

The probe pauses after each step for about three Mars days (sols). It cools down for about two days after several hours of hammering, which causes friction and generates heat. Then, it measures the thermal conductivity of the soil at a sufficient depth for one day. "For this purpose, a piece of foil in the shell of the Mole is heated for several hours with a known electrical power," says DLR planetary researcher Matthias Grott. "The simultaneously measured increase in the temperature of the foil then gives us a measure of the thermal conductivity of the soil in its immediate surroundings." In addition, the radiometer mounted on the InSight lander measures the temperature of the Martian soil on the surface, which fluctuates from some degrees above zero degrees Celsius to almost -100 degrees Celsius. Later on, once the target depth has been reached, the data from the temperature and thermal conductivity measurements, along with the radiometer data, is received at the DLR control centre in Cologne, processed and then evaluated by scientists at the DLR Institute of Planetary Research.

This is what the ground looked like after inSight landed on Mars
by Evan Gough, Universe Today
[Image: thisiswhatth.jpg]Credit: NASA/JPL-Caltech
When InSight landed on Mars on Nov. 26th, 2018, it deployed a parachute to slow its descent through the thin Martian atmosphere. As it approached the surface, it fired its retro rocket to slow it even more, and then gently touched down on the surface. As it did so, its retro rockets excavated two small pits in the Martian soil.

Once InSight was settled on the smooth surface of Elysium Planitia, it took stock of its surroundings and checked out its systems. On December 14th, the 18th Martial day (sol) of the lander's projected 709 sol mission, it used its Instrument Deployment Camera (IDC) to capture this image of the gnarly Martian surface. Clearly visible are two pits excavated by the landers rockets.
InSight's mission is to understand the internal structure of Mars. In turn, scientists will learn how Mars, and other rocky planets in the solar system, formed.
It's safe to say that InSight's primary instrument is the Heat Flow and Physical Properties Package (HP3.) HP3 has to hammer its way into the surface of Mars to do its job, and it's having problems. As reported in Universe Today last week, HP3, or the Mole, as its known, has stalled at a depth of about 30 cm (11.8 inches.)
NASA and DLR engineers are working on the problem, and they think that cavities have opened up between the Mole and the soil. Since the hammering action of the Mole relies on friction with the soil to penetrate to its required working depth, these cavities are creating problems. Engineers are going to try to use InSight's robotic arm to lift the Mole's support structure away from the probe.
Once they've lifted it away, they can get a better look into the hole and see what the problem is. They may also be able to use the arm to help the Mole work its way into the soil. The problem is, there's a risk of removing the Mole from the soil. And if that happens, it's likely game over. They have no way of gripping the Mole directly and placing it somewhere else.

and was supposed to go down 10 feet or more.

then I said this about the probe on the surface there:

Trashing the trash.
Maybe they will get lucky and loosen up the bigger rock that they hit.
Surface conditions often reveal a grading of larger denser rocks -- the deeper you go.
When I go Jade hunting, often a big flat 200 pound jade might be laying flat,
just 6 inches under the surface,
and you might walk over that spot for years and never see it.
Then one year the water changes flow in an odd way,
and washes away the 6 inches of small rocks and gravel over it, 
exposing a 8 inch flat section of the 3 foot long and 1.5 foot wide flat top.
Then it takes me an hour to expose and lift the whole rock up a bit ... with my crowbar.
They might have hit a 200 pound rock,
is what I am saying.
They need an extra robotic arm ... with a 20$ crowbar.
Or they might get lucky and fix their "lack of friction" problem, and get the mole going again,
just to hit another large rock another foot down.

Nonsense technology applied to a mission with insufficient funding.
Making work for ridiculous robotics technology.

Might as well send George Haas and the Ever Ready rabbit there instead,
to burrow that hole down ten feet,
with a shovel, a pick, crowbar, and rabbit with a flashlight to illuminate the rabbit hole.
Then George can call it the Rabbit Hole geoglyph.

Leave NASA on Earth to dig holes with toothless moles.

So if I found this as an artifact relic mission craft sitting on the surface of future Mars ....
