Tech: NASA & InSight sets a first tool on Mars – (Report)

InSight NASA Lander has used its first instrument to Mars's surface, completing an important milestone mission. New images of the lander show the seismometer on the ground, and a copper color lightly illuminates in the Martian night. It looks like everything is quiet and everything is brilliant to InSight, ending the year.

"The InSight timetable of Mars activities has gone better than we were hoping," said Tom Hoffman, InSight Project Manager, who is located at NASA's Jet Propulsion Laboratory in Pasadena, California. "Getting the seismometer safe on the ground is an incredible Christmas present."

The InSight team has been working closely towards using its two dedicated science equipment to the Martian soil since landing on Mars on November 26. Meanwhile, the Rotation Experiment and Tu Structure ( RISE), which has no separate instrument, has already started using the InSight radio connection with Earth to collect preliminary data on the core of the planet. Scientists have not taken enough time to deduct what they want to know – scientists estimate that some results may start about a year.

To use the seismometer (also known as the Seismic Experiment for Internal Structure, or SEIS) and the heat presser (also known as the Heat Flows and Physical Property Process, or HP3), first engineers had to check the robotic arm that could arise and place where InSight's instruments on Martian's surface work very well. Engineers tested the orders for the land, ensuring that a model in the test bed in JPL has used the instruments just as intended. Scientists had to analyze images of the Martian land around the banks to calculate the best places to use the instruments.

On Tuesday, December 18, InSight engineers sent the spaceship orders. On Wednesday, December 19, the seismometer was placed directly on the ground directly in front of the banks, about as far as the arm can reach – 5.367 feet, or 1.636 meters away).

"The use of seismometer is as important as landing InSight on Mars," said InSight, Principal Investigator Bruce Banerdt, who has also located in JPL. "The seismometer is the highest priority tool on InSight: We need to complete about three-quarters of science objectives."

The seismometer allows scientists to conquer into Marsh by studying an earthquake – also known as marsquakes. Each slider acts as a type of flash-bulb that illuminates the inside structure of the planet. By analyzing how seismic waves go through the layers of the planet, scientists can deduct the depth and composition of these layers.

"Having the seismometer on the ground like keeping a stick up to your ear," said Philippe Lognonné, the principal SEIS researcher from the Institut de Physique du Globe de Paris (IPGP) and the University of Paris Diderot. "We are delighted that we are now in the best position to listen to all the seismic waves below the bottom of Mars and its deep depth."

In the next few days, the InSight team will work on the leveling of the seismometer, which sits on the land that has been discharged from 2 to 3 degrees. The first seismometer science data should begin to flow to the Earth after the seismometer is in the right position.

But engineers and scientists at JPL, National National National Space Agency (CNES) National Space Agency (CNES) and other organizations associated with the SEIS team will need several more weeks to ensure that the data and returned as clearly as possible. For one thing, they will verify and possibly adjust the long-wire seismometer wire tether to reduce noise that could travel along the seismometer. Then, in early January, engineers expect to order the robotic arm to install 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 intends to use the heat examiner on the Martian surface by the end of January. HP3 on the eastern side to the workplace of the heater, around the same distance away from the landing as the seismometer.

Nowadays, however, the team focuses on getting the first pieces of seismic (but noisy) data back from a Japanese surface.

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

JPL manages InSight for NASA Science Mission Directorate in Washington. InSight is part of the NASA Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. Lockheed Martin Space built in Denver the InSight spacecraft, including its cruise and landing period, and supports spacecraft operations for the mission.

A number of European partners, including CNES and the German Aerospace Center (DLR), support the InSight mission. CNES provided SEIS to NASA, with the chief researcher in IPGP. Significant contributions came to SEIS of IPGP, the Max Planck Foundation for Solar Systems Research in Germany, the Swiss Technology Institute in Switzerland, Imperial College and Oxford University in the United Kingdom, and JPL. DLR provided the Heat Flow Pack and Physical Persons (HP3), with significant contributions from the Space Research Center of the Polish Academy of Sciences and Astronika in Poland. The Spanish Astrobiology Center gave the wind sensors.
