AIR CAR

The permission was granted after successfully completing all stages of the test flight, the British media Daily Mail reported in a report on Wednesday. It has been said that the hybrid vehicle called 'Aircar' can also run on the road. In less than three minutes, it could turn from a car into a flying vehicle. It is known that conversion can be started with just the push of a button.

The 'Aircar had to fly experimentally for about 60 hours to get permission to fly in the sky. This time it has taken off and landed more than 200 times. The aircar needs only 300 meters of runway to fly in the sky. The 'Aircar can travel at a speed of 160 kilometers per hour. Can go up to about one thousand kilometers.

In 2016, Uber unveiled a prototype of a flying taxi that looked like a drone. German flying taxi startup Lilium has so far attracted
Investment 365 million, or Rs 3,224 crore. To fly in the sky, an 'Aircar only needs a 300-meter runway. The 'Aircar can travel at a speed of 160 kilometers per hour. Can go up to about one thousand kilometers. 

 BLACK TIRES

Ever wondered why bicycle or car tires are always black? The main raw material of tires i.e. latex or rubber is white in color. But when the tire is made, why is it black?

When the tire was first made in 1895, however, its color was white. So why black now? Many may say that black is the reason why tires get stuck in the road due to dust, sand, dirt, and mud. But no. You may be surprised to hear the reason behind this.

Carbon black is mixed with rubber to extend the life and durability of tires. Not just for durability, the grip of a tire is consumed by driving a car or bicycle for long periods of time, becoming hot on friction with the road. As a result, there is a risk of an accident due to a flat tire at any moment. But carbon black plays an important role here. This helps control tire temperature.

The sun's ultraviolet rays also harden the tire's rubber. As a result, the life of the tire is reduced. But carbon black protects the tire from ultraviolet rays.

However, this does not mean that tires of other colors are not made. However, judging by the durability aspect, the companies that manufacture tire color black. However, black-colored tires are made more.

SpaceX's Rocket Is Hitting The Moon

An Elon Musk-powered SpaceX rocket is about to land on the moon after nearly seven years of uncontrolled orbit in space.

The Falcon Nine rocket took off from Florida in the United States in February 2015 with a weather satellite.

But after sending the satellite into its orbit, its engine malfunctioned. The engine slowly burned and part of the rocket was abandoned. 

The rocket lost its ability to return to the Earth's atmosphere as it moved to a sufficient height. It stops at a place where the gravitational forces of the Earth and the moon exist again. So since February 2015, the rocket has been orbiting the Earth and the moon in a chaotic orbit. 

Space observers say the rocket, weighing about four metric tons, will hit the moon at a speed of 2.56 kilometers per second in the next few weeks. 

Bill Gray, who uses software to determine the motions of objects, asteroids, asteroids, and comets around the Earth, said the Falcon Nine would hit an area near the Moon's equator on March 4. He also said that there is no precedent of such space junk falling on the moon. 

He added that the incident would take place on the other side of the moon which is visible from the earth. And there are doubts as to whether we could see it even if it happened on this side. Because the incident will happen a few days after the new moon.
