Apollo 15 and Apollo 16 missions footage👨‍🚀

✨It shows people in spacesuits bouncing around the Moon, tripping and falling. The clumsiness of the astronauts is that even though they weigh less on the Moon, their mass remains the same.

And so inertia, which is the property of a body to resist changes in motion, related to mass rather than weight, also remains the same. Thus, astronauts moving on the moon do so under completely different conditions they are used to.

These drops have also been the object of scientific research. For example, one of the objectives of the Apollo 16 mission was to assess the differences between dexterity and movement on Earth and on the Moon to better understand both lunar gravity and how it affects movement on its surface✨

On Earth, the flame spreads upwards, while in weightlessness it sweeps evenly in all directions.

✨The spherical shape of the flame is explained by the fact that in weightlessness there is no upward movement of air and no convection of its warm and cold layers, which on Earth "pulls" the flame into a drop shape✨.

Korolev Crater footage

✨The Mars Express probe took images of the Korolev Crater, which is 82 kilometers across and located in the northern lowlands of Mars, just south of the large dune-filled area that surrounds part of the planet's northern polar cap (known as Olympia Undae).

It is a particularly well-preserved sample of a Martian crater; it is not filled with snow, but ice, with a year-round mound of water ice about 1.8 km thick at its center✨

Is there sound in space?

✔️ Sound is a physical phenomenon generated by the oscillating motion of gas/solid/fluid particles. Most commonly, in everyday life, we hear sound through gas, i.e. air. 
 
If one means a spaceship, which is filled with air, then, certainly, we will hear everything perfectly, but in open space there are no air molecules, so you can enjoy the silence. 

Only not for long, since your eardrums in outer space are ruptured due to the difference in pressure inside and outside (you may feel something similar in an airplane)✨

Did you know😱?

✨The spacesuit has a device designed to protect your ears from pressure drops?

These devices come in handy if your ears start to get stuffy. Astronauts can also use them to scratch their noses✨

What occurs when a meteorite falls on the Moon?

Not as simple as you might think. The energy released from the impact melts its fragments, some of which cool down and may become small beads. 

Such "beads" were found in some quantities in the lunar soil samples brought back to Earth by the Apollo ships. 

The photo represents one of these beads enlarged to a realistic size of a quarter of a millimeter.

The first Star Wars featured the now-cult planet Tatooine with two suns

✨At the time (1977), astronomers did not yet know if such solar systems actually existed. As a result, the first extrasolar planet was discovered only in the early 1990s. 

The first true extrasolar planet was found in 2005, and it was a Jupiter-sized planet orbiting a system of a Sun-like star and a brown dwarf✨

Where did the Earth get its magnetic field🌏?

✨Scientists have now concluded that the Earth's core is a huge electromagnet. Theories of the magnetic field's origin are plentiful. To me, the most convincing is the flow of currents in the liquid metal core (external).

The Earth's core is known to consist of two parts: a solid and inner core, which is under tremendous pressure and contains mostly iron and part of the molten outer part made of nickel, and all this substance of iron mixed with nickel is constantly in motion. 

The magnetic field is created by convective flows in the outer core. These flows are maintained by temperature differences between the solid inner core and the Earth's mantle✨

Meteorite of Sericho☄️

✨As it turned out, Eastern Kenya is home to hundreds of such meteorites. Locals sold a meteorite weighing 107 kg to a collector in 2017. Following that, the inhabitants were able to collect almost a ton of fragments for subsequent sale.

Sericho is a member of the pallasite class, which includes iron-nickel alloy and yellow crystals of the mineral olivine. Olivine accounts for up to 70% of the meteorite's bulk, with the remainder made up of iron, nickel, cobalt, and phosphorus.

Currently, the total weight of the discovered meteorite fragments exceeds 2800 kg✨

BREAKING NEWS🌏📌

✨According to NASA and Copernicus, 2022 was the fifth-warmest year on record for the whole planet. The warmest 12 months on record were recorded in certain regions of the planet, including western Europe, the Middle East, Central Asia, China, and northwestern Africa. Worse yet, according to new data from the world's leading climate monitoring agencies, polar regions continued to warm rapidly last year even as levels of warming greenhouse gases in the atmosphere reached all-time highs.

This week, NASA, the U.S. National Oceanic and Atmospheric Administration (NOAA), and the European Environment Monitoring Program Copernicus each released their own projections of how quickly the climate would change in 2022. These projections show an unabated rise in world average temperatures✨

The person who captured the satellite

✨This photograph, taken from the space shuttle Discovery in 1984, shows astronaut Dale Allan Gardner doing a spacewalk with a controlled maneuvering satchel.

To make it simpler to position the rotating Westar 6 satellite inside the shuttle, he connected a control device to it. Following that, the satellite was lowered to Earth aboard the shuttle and sold after being repaired✨

NASA's Z2 space suit prototype

✨It's a spacesuit made specifically to travel to Mars, not just another one. It is true that the fitting to a specific person will be done using a three-dimensional printer and laser scanning.
NASA plans to build Martian spacesuits using the most recent advances in science and technology✨

Moon dust is hazardous to humans.
✨Scientists have studied the lunar dust extracted by astronauts.The conclusions were disappointing: the minerals it contains cause lung cancer in humans.To confirm the theory, studies were conducted on the cells.In 90 percent of cases, they died✨

Radiation and Magnetic Field

✨The interaction of the Earth's magnetic field with the solar wind results in the formation of radiation belts (Van Allen belts), two rings of ionized gas trapped in orbit around the Earth by the magnetic field.
The outer radiation belt has altitudes ranging from 19,000 km to 41,000 km, while the inner radiation belt has altitudes ranging from 7,600 to 13,000 km.✨
