Researchers Say The ‘Proton Aurora’ is The Most Common Type of Aurora on Mars

The researchers say that the ‘proton aurora‘ is the most common type of aurora on Mars. The proton aurora, a type of Martian aurora, was first identified in 2016.


When solar wind protons interact with hydrogen in extended parts of the Martian atmosphere and travel to lower regions. According to observations made over several years.


And using the Ultraviolet Imaging Spectrograph (IUVS) on NASA’s MAVEN spacecraft (Atmosphere of Mars and Volatile Evolution), the phenomenon is actually the most common form of aurora on Mars; This is seen in 14% of MAVEN / IUVS data on Mars day.


Which is much higher than initially expected. Images of the proton aurora on Mars: MAVEN’s IUVS instrument monitors the atmosphere of Mars, creating images of neutral hydrogen.


And proton aurora simultaneously (left); Observations in normal conditions show hydrogen in the disk and from the point of view during the night (in the middle) to the extended atmosphere of the planet.


The proton aurora appears as a critical luminosity in the organ and the disc (right); With the contribution of neutral hydrogen, the distribution of the proton aurora is detected.


Which shows that it resembles the brightness peaks of the Mars disk, as well as the neutral energy impacted in the atmosphere. “Previously, we believed that proton auro events were rare.


Because we weren’t looking at the right times and places,” said Dr. Mike Chaffin, a researcher at the Boulder Laboratory of Atmospheric and Space Physics at the University of Colorado.


But after a closer look, we discover that the proton aurora is occurring more frequently during the southern summer days than we initially expected.

MAVEN’s mission is to test how much Mars has lost its atmosphere and water, changing its climate from one to a cold, dry and inaccessible life.


Since the proton aurora is generated indirectly from the water produced by Mars, which is in the process of being lost in space, this phenomenon can be used to help track the ongoing water loss.


“In this new study that uses MAVEN / IUVS data for several years on Mars, we find that the period of greatest atmospheric migration coincides with an increase in the occurrence.


And intensity of aurora protons,” said Dr. of the Space Research Center and Atmospheric Andre Hughes and the Department of Physics of the University of Embryology-Aeronautics said.


Perhaps one day, when the planetary journey becomes common, travelers arriving on Mars during the southern summer will have front-row seats to see Martine’s protonic aurora that dances prominently during planetary days.


On Earth, the north and south lights are produced when the solar wind (electrically charged particles from the Sun) reaches the poles following the lines of our planet’s geomagnetic field and collides with the upper atmosphere.


Mars lacks a global magnetic field, so solar wind accumulates in front of Mars in an arc of shock, which prevents charged particles from reaching most of the atmosphere.


However, in a process first seen by NASA’s MAVEN spacecraft, some solar wind protons can reverse the arc shock by first joining with electrons from the Martian upper atmosphere to create hydrogen atoms.


Because these hydrogen atoms are electrically neutral, they can suffer an arc shock and proceed to form auroras of ultraviolet protons on Mars.

The study authors found the proton aurora in approximately 14% of their daytime observations, which increases to more than 80% of the time when only the observations of the southern summer are considered.


“By comparison, IUVS has detected the isolation of the aurora on Mars in some percentage orbits with favorable geometry, and discrete auroras fragments are still rare in the data set,” said Dr. Nick Schneider.


And also atmospheric and Laboratory of Space Physics of the University of Colorado, Boulder. “All the conditions necessary to create a proton aurora on Mars (for example, the absence of a solar wind proton.


And an expanding hydrogen atmosphere and a global dipole magnetic field) are more available than those of Mars that form other types of auroras. ” They are necessary for, “said Dr. Hughes.


“In addition, the relationship between MAVEN’s observations of atmospheric leaks and an increase in the frequency and intensity of the proton aurora means that the proton aurora will actually be used as a proxy for what is happening in the hydrogen crown around Mars.


And therefore, to be an indicator of the increase in atmospheric migration time and water scarcity. The study was published in the Journal of Geophysical Research.


Space Physics. A new study of strange auroras on Mars revealed something we did not expect: If we ever take it to Mars, the first visitors will visit some of the attractions of this world.


But to see the majestic auroras that roam the sky of Mars during the day, they need ultraviolet. A new study has found that a particular type of aurora, the proton aurora, is the most common form of occurrence on Mars.


As on Earth (including northern lights), proton auroras form when solar winds come into contact with the atmosphere. However, these auroras are not just beautiful places to take cameras with UV.


They can help us understand how Mars’s climate is changing and how water is going to space on the red planet. Proton auroras form when solar winds collide with the gigantic hydrogen cloud around Mars.


And positively charged protons are neutralized by taking electrons from hydrogen atoms. These interactions emit ultraviolet light, and because the water lost in space creates a cloud of hydrogen.


Which can give scientists a way to measure water loss over time. The observations of the proton auroras on Mars provide a unique perspective of hydrogen and, therefore.


The lack of water on the planet, says physicist Edwin Mirkivic of the Embry-Riddle Aeronautical University in Florida. Through this research.


We can gain a deeper understanding of the Sun’s interactions with the upper atmosphere of Mars and in our solar system, or in another solar system that lacks a global magnetic field.”


Proton auroras were first detected by NASA’s Maven spacecraft in 2016, and in particular by their ultraviolet imaging spectrograph instrument (IUVS), but this new research makes it clear that they are the most common type of aurora in the planet.


The new analysis revealed proton auroras in 14 percent of daily observations in the MAVEN dataset, and 80 percent of daytime observations during southern summers on Mars, when the planet is close to the Sun.


“At first, we believed that these events were rare because we weren’t looking at the right times and places,” says planetary scientist Mike Chaffin of the University of Colorado Boulder.


But after a closer look, we discover that the proton aurora is occurring more frequently in the southern summer days than we initially expected.


Due to the increase in dust and summer heat, water vapor reaches higher altitudes, where the sun’s UV light divides it into hydrogen and oxygen. In turn, this condenses the hydrogen cloud in the atmosphere and increases the auroras of protons.

These latest findings have not yet been published in a peer review journal, but we can expect more results and analysis in the coming months and years: studies that track water damage on Mars These protons can use aurora UV light.


The researchers say that the ‘proton aurora‘ is the most common type of aurora on Mars: the proton aurora, a type of Martian aurora, was first identified in 2016, when solar wind protons interact with hydrogen in extended parts of the Martian atmosphere.


Meanwhile, it is interesting to think that the magnificent auroras appear almost every day during the Martian summer, whenever you are looking for the right equipment. This is something for those who arrive early and want to see more.


“Maybe one day, when the mutual journey becomes a common place, travelers arriving on Mars during the southern summer will have seats in the front row to observe Martine’s protonic aurora, which dances brilliantly during the days of the planet, in ultraviolet.


Use of sensitive glasses, of course, “he says. The planetary scientist Andre Hughes, of the Embry-Riddle Aeronautical University. The research is presented at a meeting of the American Geophysical Association. Do and travel to the lower regions.


According to observations made over several years using ultraviolet imaging spectrographs (IUVS) on NASA’s MAVEN spacecraft (Mars and the atmosphere of unstable evolution).


The event is actually the most common form of the aurora on Mars. This is seen in the data of 14% of MAVEN / IUVS on Mars Day, which is much higher than initially expected.


Proton Aurora images on Mars: MAVEN’s IUVS device monitors the atmosphere of Mars, creating images of neutral hydrogen and proton aurora simultaneously (left).

Observations under normal conditions show hydrogen in the disk and at night (in the middle) of the planet’s extended atmosphere. The proton aurora appears as an important luminosity in the organ and the disc (right).

With the contribution of neutral hydrogen, the distribution of the proton aurora is detected, which indicates that it resembles the luminous peaks of the Mars disk.


As well as the impacts of neutral energy in the atmosphere. Previously, we believed that proton auro events were rare because we were not looking at the right times and places, “said Dr. Mike Chaffin.


A researcher at the Boulder Laboratory of Atmospheric and Space Physics at the University of Colorado. But one closer after Look, we discovered that the proton aurora is occurring more frequently than we started in the summer days of the south.


The mission of MAVEN is to prove this It is to prove how much Mars has lost its atmosphere and water, changing its climate of a life cold, dry and inaccessible one by one. Because the proton aurora is generated indirectly by the water created by Mars, which is space.


This phenomenon can be used to help track the continuous damage of water, in the process of getting lost. this new study that uses data from MAVEN / VUVS Rat.For several years on Mars.


We found that the period of the highest atmospheric migration coincides with the increase in the occurrence ncia and intensity of the aurora protons, “Dr. from the Andre Space and Atmospheric Research Center.


Hughes and the Department of Physics of the University of Physiology Aeronautics said. Maybe one day, when planetary travel becomes common.


And travelers arriving on Mars during the southern summer will have seats in the front row to see Martine’s protonic aurora dance prominently during planetary days.


On Earth, north and south light is produced when the solar wind (electrically charged particles from the Sun) reaches the poles along the lines of our planet’s geomagnetic field and hits the upper atmosphere.


Mars lacks a global magnetic field. So the solar wind accumulates like a shock against Mars, preventing charged particles from reaching most of the atmosphere. However, in a process first seen by NASA’s Maven spacecraft.


Some solar wind protons can first reverse the arc shock by joining with electrons from the Martian upper atmosphere to form hydrogen atoms.


Because these hydrogen atoms are electrically neutral, they can withstand the impact of an arc and move on Mars as sets of ultraviolet protons. Image by NASA Goddard Space Flight Center.

An expanding hydrogen atmosphere and a global dipole magnetic field) are more available than those of Mars that make up the Auroras. “They are essential,” said Dr. Hughes.


In addition, MAVEN observes observations of atmospheric leaks. The relationship between and an increase in the frequency and intensity of the proton aurora means that the proton aurora will be used. Really as a proxy.


Mars F. What is happening in the hydrogen crown, and therefore, should be an indicator of an increase in atmospheric graduation and lack of water. It was published in the Placenta geophysical research journals.
