Carbonate keep the age of a fossil for tens of years.
Institute of aeronautics and Space Ameriksa States (NASA) announced the exploration mission of the Crater Jezero on Mars in 2020. Crater Jezero is an area of geological conditions of the alluvial deposits.
Scientists suspect there are organic molecules ancient look through satellite imagery. In addition allegedly still a lot of things stored in this fella.
In the image of silhouette, light, visible form of a ‘bathtub ring’ berkarbonat. Presumed to be a place to accommodate the fossil.
Reported Science Alert, exploration mission Mars 2020 raise the possibility of habitability of Mars. Robot explorers, Spirit and Opportunity were sent to Mars with a mission to find evidence of water, both ancient and modern.
Crater Jezero selected with some consideration. First, this crater is an area of the ancient site of the lake is estimated appeared about 3.5 billion years ago.
Rings Carbonate
Carbonate can make the structure of the fossils of long-lived which can last up to billions of years. Including shells, coral, and stromatolites.
Scientists think it’s worth investigating rings carbonate around the edge of the Crater Jezero to see if there are fossils in there. No one knows what will be found there, at the edge of the crater rich in carbonate.
But, empirical evidence that location is the place to look for traces of the nature of Mars.
A paper published in the journal Icarus presents a detailed view into the diversity of minerals in the Jezero Crater, including the deposition of carbonate in the hem. The paper is titled, The mineral diversity of Jezero crater: Evidence for possible lacustrine carbonates on Mars.
NASA Recorded the Sound of Mars
Mars continues to be a puzzle. Even so, the Space Agency and Flight of the United States (NASA) test some of the natural phenomena on Mars.
Through explorers NASA, the InSight is equipped with “ears” that are very special. The tools embedded in the InSight it’s called the Seismic Experiment for Interior Structure (SEIS), which can capture the subtle vibrations as the gentle breeze.
These instruments are made space agency of France, the Centre National d’études Spatiales (CNES).
SEIS is designed to listen to the marsquake. Scientists want to study how seismic waves on the planet Mars.
But, after the seismometer is lowered by the robot arm InSight, Mars looked embarrassed. The first rumble of the new Mars appear until April 2019.
The rumble that had a seismic signal high frequency surprising science team. More than 100 events detected to date, about 21 highly regarded as a earthquake.
Earthquake
Wear headphones to listen to two of the earthquakes detected SEIS. The incident happened on May 22, 2019 (or use the day of the mission on Mars, sol 173) and July 25, 2019 (Sol 235).
The sound of it is far below the range of human hearing. Sonifikasi of the SEIS is to be speeded up and slightly processed to be audible through headphones.
Mechanical noise and Wind Gusts
In addition to susara earthquake, SEIS also record gusts of wind on Mars. Scientists need to sort out the sound which really comes from the gusts of wind on Mars.
“Very fun, especially in the beginning, hearing the first tremors of the lander,” said Constantinos Charalambous, a member of the science team InSight at Imperial College London reported NASA.
“You’re imagining what’s really happening on Mars as InSight sits on the open landscapes,” he said.
The Sound Of `Tik`
Charalambous and Nobuaki Fuji from the Institut de Physique du Globe de Paris provides a sample of the audio for this story, including the one below, which also best heard with headphones and catch a variety of sounds that they hear.
Team InSight had heard a strange sound at night dubbed dinks and donks.
The voice alleged to arise due to contraction of the summer, similar to the sound of `tik` after the car’s engine off and cold start.
You can hear a dink and donks in a series of next sound, which was recorded right after sunset on July 16, 2019 (Sol 226).
Listen well and You can also hear a whistling scary that according to the team may be caused interference on the electronic devices of the seismometer.
