The sky on Mars has a wind of ultraviolet light that pulses as it moves across the red planet.
This phenomenon is similar to Earth’s aurora borealis events, lasting from sunset until midnight, and NASA has created a new animation using data obtained from an instrument on the MAVEN spacecraft to demonstrate what it might look like to future astronauts in orbit. That is, it’s what they would see if it wasn’t invisible to the naked human eye.
“The ultraviolet glow comes mostly from an altitude of about 70 kilometers (approximately 40 miles), with the brightest spot about a thousand kilometers (approximately 600 miles) across, and is as bright in the ultraviolet as Earth’s northern lights,” explained Zac Milby, a researcher at the University of Colorado’s Laboratory for Atmospheric and Space Physics (LASP).
Milby is one of several other LASP scientists that published a recent study on the ‘nightglow’ data in the journal JGR Space Physics. The team analyzed two Martian years’ worth of images taken by the Imaging Ultraviolet Spectrograph (IUVS) on the Mars Atmosphere and Volatile Evolution (MAVEN) mission spacecraft to find the reported wind and UV emission behavior. “The MAVEN spacecraft orbiting Mars has obtained a new type of imaging data which reveals the effects of global‐scale winds and waves in the upper atmosphere,” the study’s Plain Language Summary details.
With a mission to Mars in the near-term travel plans for both NASA and SpaceX, learning as much as possible about the planet’s atmosphere is essential. Preparations for both on-site scientific study and astronaut safety will need to incorporate the Martian ground conditions, so studies like this one provide very important and relevant data. The recent findings also demonstrate the importance of cooperative international efforts in exploring deep space, namely because MAVEN wasn’t the first spacecraft to demonstrate the existence of the ‘nightglow’ phenomenon. Rather, the European Space Agency’s Mars Express orbiter mission revealed it in 2003, leading the path for follow up and further study.
It may also be interesting to note that although Mars-based astronauts may not be able to see the UV aurora-type nightglow with their normal eyesight, instruments could likely come into play to overcome such limitations. We already have commercially available UV cameras on Earth, for instance. There’s even a UV camera smartphone add-on that one could see being used on Mars to watch the glow show in a similar fashion to augmented reality starfinders on the market.
Of course, much more science-oriented UV cameras would likely accompany any travelers to the planet, but it’s fun to imagine what may be available to more tourist-types or even Martian colonists some day.

In Germany, where there are currently 9,900 active COVID-19, the transition to a strict quarantine regime is discussed.
According to the European bureau of the Report, 9,200 people died of the infection so far.
The most deplorable situation is in the province of North Rhine-Westphalia, where Azerbaijanis also live compactly. Currently, the number of active coronavirus cases in this federal land has exceeded 4,000. The beginning of the new school year worries most parents. A teacher and a student at a school in Mecklenburg-Vorpommern last week got infected virus as the new school year began. After that, the school was closed again, and the scholars were quarantined at home.
Parents say it is not easy to ensure social distance, masks, and hygiene among students in North Rhine-Westphalia schools. Thus, the Council of Parents of educational institutions has officially appealed to the Ministry of Education of the province to postpone schools’ opening for some time. They noted that if this was not possible, the number of students in the classrooms should be minimized, one student should come to school twice a week, and the rest of the week to attend online classes at home.
Germany relaxed the lockdown regime in May. Quarantine rules are currently applied due to pandemic, such as a 1.5-meter social distance, wearing masks indoors, and not allowing more than two people from the same family to gather together.
As technology companies race to put self-driving vehicles on the road, some Chinese companies are launching taxi pilot projects in cities.
It is expected to be years before cars that operate completely without humans are unleashed owing to lingering technological, regulatory, and safety hurdles.
Chinese companies such as Baidu, Alibaba-backed AutoX and ride-sharing king DiDi Chuxing are launching projects.
Similar efforts are underway in the US, and AutoX’s chief executive Xiao Jianxiong told AFP the first fully-autonomous vehicles could be on the roads by the end of the year.
Chinese consumers were lining up for a spin in DiDi Chuxing’s self-driving taxis at a Shanghai pilot project launched in June.
The first stage of the Azerbaijani-Turkish Live-Fire Joint Large-Scale Tactical Exercises continues with the participation of units of the Land Forces, Report says, citing Defence Ministry.

Twin explosions caused a humanitarian crisis that killed more than 100 and wounded approximately 5,000 others.
The blast also damaged properties and vehicles, and the crisis left 300,000 people homeless.
The Lebanese government has declared a two-week state of emergency. According to the Associated Press, it has put Beirut port officials under house arrest and opened an investigation into the storage of explosive materials.
Lebanon is now in a three day mourning period to show compassion for and solidarity with relatives of people who lost their lives.
Within the Annual Action Plan approved by the Minister of Defense, the Army Ideological and Cultural Center named after Hazi Aslanov has carried out activities on fulfillment of the tasks in the field of strengthening ideological work and increasing the military-patriotic spirit in the Azerbaijan Army, according to Azerbaijan’s Defense Ministry.
The tasks were assigned by the President of the Republic of Azerbaijan, Supreme Commander-in-Chief of the Armed Forces, Mr. Ilham Aliyev in his last speeches.
The events were attended by soldiers and officers of military units, as well as Honored Artist of Azerbaijan Agalar Bayramov.
First, the memory of the national leader Heydar Aliyev and the Shehids (martyrs) who sacrificed their lives for the sovereignty and territorial integrity of the Republic of Azerbaijan was honored with observing a minute of silence. The National Anthem of the Republic of Azerbaijan was performed.
Speakers at the solemn ceremonies spoke about the importance of ideological work, stages in the history of Azerbaijan statehood, the Armenia-Azerbaijan, Nagorno-Karabakh conflict, and the Tovuz battles that happened as a result of the provocation of the armed forces of Armenia.
The military personnel was presented with a video with the speech of the President of the Republic of Azerbaijan, Mr. Ilham Aliyev, and a historical chronicle about the statehood and military history of Azerbaijan.
Honored Artist A. Bayramov recited poems dedicated to the Motherland, the Flag of Azerbaijan, and Shehids (martyrs).

The events ended with a concert program consisting of military-patriotic songs and military marches presented by the Army Ideological and Cultural Center.
Moscow-based tech giant Yandex today announced it had expanded testing of its self-driving cars to Michigan. A fleet of Yandex’s driverless vehicles recently hit Ann Arbor city streets, including the company’s fourth-generation autonomous Hyundai Sonatas created in partnership with Hyundai Mobis.
Yandex says it had planned to provide rides in its autonomous taxis in Detroit during the North American International Auto Show (NAIAS), which was scheduled to take place in June. The company had already done a significant amount of preparatory work by mid-spring. When NAIAS was canceled in April, Yandex began searching for a Michigan location to facilitate longer-term commercial testing.
Yandex says Michigan’s “progressive” and “supportive” regulatory environment will enable “rapid” development and advancement. Unlike Moscow, Tel Aviv, and Las Vegas, where Yandex also conducts testing, Ann Arbor allows operators autonomy — driverless cars aren’t required to have safety drivers behind the wheel. The central Russian college town of Innopolis, where Yandex operates a Robo-taxi service, is the only location in the country that lets autonomous cars transport passengers without a driver.
Michigan also allows companies to test cars without driver controls like steering wheels and pedals. The state also permits the public sale of autonomous vehicles once they have been tested and certified.
Yandex’s driverless vehicle fleet has racked up over 3 million autonomous miles. The aforementioned retrofitted Sonatas are responsible for a portion of those, alongside the company’s over 100 autonomous Toyota Priuses. Work on Yandex’s self-driving car platform began in earnest in 2016.
Another stage of the Azerbaijani-Turkish Live-Fire Joint Large-Scale Tactical Exercises held in our country following the Agreement on Military Cooperation was conducted.
Report informs citing the Ministry of Defence.
According to the exercise scenario, the units performed various combat elements and other combat-training missions using armored vehicles and helicopters.

The units completed the assigned tasks, demonstrating high professionalism in interoperability with other battle formation elements.
Israeli officials have denied involvement in the Beirut port explosion.
“Israel has nothing to do with the incident,” the official said on condition of anonymity, according to Reuters.
The country’s foreign minister, Gabi Ashkenazi, told Israeli N12 television news that the explosion was most likely an accident caused by a fire.
Tensions have been high this week following a cross-border confrontation between Israel and the Lebanese militant group, Hezbollah.
“Everyone in Cyprus felt it,” said the person, who asked to be referred to only by his first name, George. “The door was shaking in my house. In Larnaca, they heard it and felt it … It was so loud we thought it happened here. My house was shaking.”
The Associated Press is quoting Lebanese Red Cross official Georges Kettaneh as saying there are “hundreds of casualties” in Beirut, including dead and wounded.
A large blast has hit the Lebanese capital, Beirut, causing widespread damage and injuring many people, officials say, BBC reported.
It is not yet clear what caused the explosion in the port area of the city. Video posted online showed a large mushroom cloud and destroyed buildings.
Hospitals are said to be overwhelmed by casualties.
It comes at a sensitive time with the country’s economic collapse reigniting old tensions.
Tensions are also high ahead of the verdict in a trial over the killing of ex-PM Rafik Hariri in 2005. A UN tribunal is due to issue its verdict in the trial of four suspects in the murder by car bomb of Hariri on Friday.
Lebanon’s health minister, Hamad Hasan, has spoken of many injuries and extensive damage.
Reuters news agency quotes sources as saying 10 bodies have been pulled from the wreckage.
The cause of the explosion is still not known, but some reports suggest it may have been an accident. Lebanon’s National News Agency reported a fire breaking out at what it called an explosives depot at the port.
Local media showed people trapped beneath rubble. A witness described the first explosion as deafening. Video footage showed wrecked cars and blast-damaged buildings.
The latest reports come amid political tension in Lebanon, with street demonstrations against the government’s handling the worst economic crisis since the 1975-1990 civil war.
There has also been tension on the border with Israel, which said last week that it had thwarted an attempt by Hezbollah to infiltrate Israeli territory.
I saw the fire, but I didn’t yet know there was going to be an explosion. We went inside. Suddenly I lost my hearing because apparently I was too close. I lost my hearing for a few seconds, I knew something was wrong.
And then suddenly the glass just shattered all over the car, the cars around us, the shops, the stores, the buildings. Just glass going down from all over the building.
Literally all over Beirut, people were calling each other from different areas kilometres away and they were experiencing the same thing: broken glass, buildings shaking, a loud explosion.
Actually we were shocked because usually when it happens, just one area will experience those happenings after an explosion, but this time it was all of Beirut, even areas outside of Beirut.
Shock and anxiety
The videos and images not just of the massive cloud of smoke erupting in Beirut but the damage and devastation it’s caused kilometres away have triggered a new wave of shock and anxiety in Lebanon, which is already teetering on the brink of a catastrophic economic collapse.
Just hours before the blast, anti-government protesters had been scuffling with the security forces outside the ministry of energy, demanding yet again accountability from the country’s leaders.
There have been grave warnings of hunger in the streets or a reigniting of sectarian conflict if the economy worsens.
And the blast will remind many of the bomb that killed Rafik Hariri. The Lebanese will be hoping that this latest blast will remain a human tragedy – an accident – and not a premeditated act.
What’s the Hariri case about?
On the morning of 14 February 2005, Rafik Hariri – then an MP who aligned himself with the opposition in parliament – was travelling in a motorcade when the explosion went off in a busy area full of hotels and banks, causing widespread damage.
Mr Hariri had been one of Lebanon’s most prominent Sunni politicians and, at the time of his death, had joined calls for Syria to withdraw troops which had been in Lebanon since 1976 following the start of the civil war.
The killing brought tens of thousands of demonstrators on to the streets in protest against the pro-Syrian government, with the finger of blame for the assassination pointed at Lebanon’s heavily influential neighbour.
Within two weeks the government resigned and weeks after that, Syria withdrew its forces.
After collecting evidence, the UN and Lebanon set up the Special Tribunal for Lebanon (STL) in The Hague in 2007 to investigate the bombing, and ultimately charged four suspects of the Iranian-backed Hezbollah group with terrorism, murder and attempted murder.
A fifth man linked to the attack, Hezbollah military commander Mustafa Amine Badreddine, was killed in Syria in 2016.
Hezbollah’s supporters have dismissed the trial, suggesting that the STL process is not politically neutral.
Due to the beginning of the second training period in 2020, a drill review of military personnel was held in Azerbaijan’s all military units, the training base and full equipment of units were checked, the Defense Ministry said on Monday.
At the events, the main goals and objectives for the training period were declared, and it was noted that exercises and classes would be conducted continuously with the aim of improving the centralized command and control of troops and achieving interoperability.
The unit commanders pledged to invite other unit commanders to the competition in order to determine the best in combat training in the new training period.
After the solemn passage, the first classes of the new training period were held in the formations and units to coordinate the interaction of the troops of the Nakhchivan garrison.
Combat missions are being clarified in the units, and the troops put in the alert are involved in combat training sessions at day and nighttime.
Azerbaijani-Turkish Live Fire Joint Large-Scale Tactical and Flight-Tactical Exercises are being held in Nakhchivan
According to the exercise scenario, the units of the Combined Arms Army, the forces structure of the Nakhchivan Autonomous Republic and the Armed Forces of the Turkish Republic have been brought into the state of full combat readiness and, on alert, were withdrawn to the exercise areas.
Continuous control of troops is practically carried out by means of control systems from command posts. Formations and military units operate in accordance with combat readiness plans.
During the exercises, which involve combat aircraft, military transport, and attack helicopters, training flights are conducted with elements of aerobatic manoeuvring.
