Researchers suggest glaciers may be hiding beneath Mercury’s surface

Published

The daytime surface temperature of Mercury can reach 230 °C. It has no atmosphere or magnetic field and appears dry and lifeless. However, it may turn out that this is not the case.

Recent research by a team of scientists from the Planetary Science Institute (Arizona) proposes a hypothesis about the presence of underground salt glaciers in the area of ​​Mercury’s north pole. The hypothesis arose despite the extreme conditions characteristic of this planet.

Based on previous discoveries of nitrogen glaciers on Pluto thanks to NASA’s New Horizons mission, scientists theorized that glaciers on Mercury may have formed as a result of water flowing from areas surrounding the planet’s core during volcanic activity in ancient times. When the water reached the polar region, it formed shallow seas that interacted with salt flows and formed frozen glaciers. This hypothesis is based on computer models with data obtained from NASA’s MESSENGER orbiter.

The underground salt glacier areas on Mercury remained cold while the planet still had an atmosphere that protected these areas from solar radiation. Liquid water could then form and persist under the icy crust.

According to the data, these areas are rich in volatile substances and create characteristic structures on the surface in the form of “sublimation pits”. Such pits are formed as a result of a process in which the material goes from a solid state directly to a gaseous state. On Mercury, where salt glaciers occur, sublimation of ice can create such pits as frozen water directly turns into a gas under the influence of vacuum and intense solar radiation. These formations can be found inside craters and indicate the processes of sublimation of ice under the surface of the planet.

If these theoretical assumptions are confirmed, they could have important implications for ideas about the existence of biomarkers in the Solar System. Underground salt glaciers on Mercury may provide habitat for extremophilic microbial life. Although they are hostile to common microorganisms, these underground glaciers may be home to unique life forms that have already been found on Earth in extreme environments such as the Atacama Desert, the Dead Sea and hot springs.

Huawei sets a record for the fastest delivery of

Huawei reported that shipments of the new Aito M7 SUV exceeded 100,000 units within 170 days of the vehicle’s launch in the Middle Kingdom. And this is a record for the speed of delivery to luxury SUV buyers in China. True, much of the credit here goes to Huawei’s partner, Seres, at whose facilities Aito cars are assembled: after all, if there were problems with production, then there would be no need to talk about any car delivery records.

The Aito M7 is a large car with dimensions of 5020 x 1945 x 1775 mm and a wheelbase of 2820. It is offered in China in seven trim levels: with 5 or 6 seats, with front-wheel drive or all-wheel drive. This car is a hybrid – with a 1.5-liter engine under the hood and one or two electric motors. On pure electricity, the Aito M7 can travel up to 260 km, the maximum range is 1300 km, and the average consumption is only 5.6 l/100 km. The all-wheel drive version accelerates to 100 km/h in 4.8 seconds.

The most environmentally friendly cars have been named in the USA. Toyota Prius Prime is in first place, Toyota RAV4 and Toyota Camry are in the top 10, but not a single Tesla car

The most environmentally friendly cars have been named in the

The American Council for an Energy-Efficient Economy (AEEE) has released its latest list of the greenest cars. Here, like the reliability ratings, Toyota dominates: 6 models from the top 12 are produced by the Japanese company and its subsidiary brand Lexus.

The most environmentally friendly cars have been named in the USA.  Toyota Prius Prime is in first place, Toyota RAV4 and Toyota Camry are in the top 10, but not a single Tesla car

The AEEE study’s findings support Toyota’s own policy: the company believes that a mix of gasoline, hybrid and electric vehicles is actually greener, given the current state of power generation and global charging infrastructure, than going all-electric.

The entire top 12 “green” rating looks like this:

  • Toyota Prius Prime SE PHEV
  • Lexus RZ 300e
  • Mini Cooper SE EV
  • Nissan Leaf EV
  • Toyota bZ4X EV
  • Toyota RAV4 Prime PHEV
  • Hyundai Elantra Blue Gas Hybrid
  • Hyundai Kona Electric EV
  • Toyota Camry LE Gas Hybrid
  • Kia EV6 EV
  • Toyota Corolla Gas Hybrid
  • Hyundai Ioniq 5 EV

The ACEEE rating is compiled taking into account factors throughout the vehicle’s life cycle: from materials and components that go into production, to its operation and subsequent processing. ACEEE evaluates each vehicle of the year based on its impact on human health due to air pollution associated with vehicle production and disposal, fuel or electricity production and distribution, and vehicle-specific emissions.

In this regard, the Prius Prime SE plug-in hybrid from an experienced automaker with streamlined manufacturing processes is much more environmentally friendly to manufacture, use and dispose of than some pure electric vehicles. The Prius Prime SE’s traction battery is several times smaller than that of the average electric car, but it is enough to cover most driving needs in the city, and the gasoline “range extender” comes into play on the highway.

It is therefore not surprising that the Hummer EV, with its large traction battery, was ranked among the dirtiest cars, along with the petrol Mercedes-Benz G550.
