The Wright Brothers showed that powered flight in Earths

Ingenuity was able to fly just 3 meters above the surface of Mars and stay afloat for only 39.1 seconds. This does not seem to be an achievement at first glance. As a result, it is much more difficult for an airplane to fly to Mars than to Earth.

So far no helicopter has been able to rise 30,000 meters above the earth’s surface. But Ingenuity has been able to fly off the surface of Mars. This is why it is not an ordinary achievement, but a unique achievement in the history of space technology.

Ingenuity’s flight to Mars is practically a ‘technology demonstration’. That is, it is not a complete technology, but an experimental version or prototype of future technology.

History of the construction of Mars missions and Ingenuity

NASA’s Ames Research Center and Langley Research Center also support research. The project’s executive officer is Dave Lavery, the project manager is Mimi Aung and the chief engineer is Bob Balaram.

Finally, in March 2017, the US government allocated 23 million (or 23 million) for the project.

Note that ‘Mars Rover’ means a vehicle suitable for navigating the land of Mars. NASA has invested a total of about 75 million (or 75 million) US dollars to build and operate this helicopter.

On the same day, the helicopter took a picture of the surface of Mars and sent it to Earth. On April 6, Ingenuity completes a low-speed ‘rotor spin test’. At this time the speed of the wings of Ingenuity was 50 revolutions / minute. Note that the job of this watchdog timer is to protect the helicopter from conducting wrong activities in unforeseen circumstances.

On April 12, NASA authorities announced that they had solved the problem by updating a software. On 17 April Ingenuity successfully performed the ‘fan rotation test’ at full speed. Finally, on April 19, the helicopter took off for the first time from the surface of Mars. Its flight time was 39.1 seconds. It is able to rise to a height of about 3 meters, turn 96 degrees as planned and then land. This completes the first powered flight to an alien planet.

On April 22, Ingenuity flew off the surface of Mars for the second time. Then it lands down. The second time Ingenuity was able to rise higher than the first time and stay afloat for longer.

According to NASA’s plan, Ingenuity will fly 3 more times from the surface of Mars in 30 solar days. It will communicate directly with the Perseverance Rover after each landing.

Naturally, this has ushered in a new era in the history of space exploration. NASA and JPL officials described the flight of Ingenuity as their ‘Wright Brothers moment’. The place from which Ingenuity flew, NASA named it ‘Right Brothers Field’.

seconds after takeoff. Its maximum speed during vertical flight is 3 m / s. The battery power used in helicopters is 35–40 watt-hours (or 130–140 kJ).

It also has a radioactivity-resistant system, which is able to withstand even the coldest weather on Mars. It has a high resolution camera and a communication system to deliver data to the Perseverance Rover.

Ingenuity also has several additional equipment. These include gyroscopes, visual odometers, inclinometers, altimeters and hazard detectors.

The helicopter uses a Qualcomm Snapdragon 601 processor with Linux operating system. It also carries an IMU and a Garmin Leader Lite V3 laser altimeter.

About a decade ago. On a sweaty summer afternoon, Minu Tiwari went to a yarn factory in Surat, western India. As an urban planner, he often visits to see how different manufacturing companies operate. But that day he discovered something that completely stunned him.

That day was a working day. There was no special holiday that day. But still he did not see any working workers. Just machines and machines all around. The whole factory environment is buzzing. After much searching, he found all the workers resting in the shade under a nearby canopy.

What is the reason for leaving work in Bharadupura rest?

Again, many people become unconscious while working on the machine. As a solution to these problems, the company has asked them to rest at this particular time of the day.

Warmth and aggression
For more than a century now, scientists have been documenting the effects of extreme heat on humankind.

That variety began with a minimum of 14 degrees Celsius, and ended with a temperature of 36 degrees Celsius.

The researchers then asked the students to score the couple’s level of mutual animosity. But the students who were sitting comfortably in the cool room did the right thing in terms of scoring.

In the light of this study, Anderson came to the conclusion that warmth makes human moods more irritable. So they also find the experiences they experience by their senses to be relatively more nasty.

Most of those days the temperature rose to a maximum of 34 degrees Celsius. But the readings obtained by the researchers did not mention the high humidity of Mississippi. So in this case there is some incompleteness in the research. Moreover, many older correctional facilities in the United States lack adequate air conditioning, and lack adequate ventilation. Therefore, the temperature inside these facilities can in many cases exceed the temperature outside.

Politicians often claim that providing air-conditioning for inmates in prisons is akin to providing them with elite comfort.

In addition, some studies have shown that global warming also increases the amount of violence outside the prison.

Warmth and performance

In this case, you can also consider the students who take exams in many hot school buildings.

UCLA economist R. Jisang Park and colleagues sought to understand how high temperatures affect student performance in different parts of the United States. In this case, they have relied on PSAT, the standardized test taken to provide scholarships to high-schoolers. They also take into account the condition of the air conditioning in a test center.

But it is not easy to cool all the buildings in a city through air conditioning. According to a 2020 UN report, global cooling equipment in 2017 accounted for 16 percent of the total electricity supplied. At the moment these energies come from oil, coal and gas.

Tiwari also thinks that ensuring air conditioning for everyone will not be an easy task.

They should not hide their disenfranchisement by making any kind of excuse.

In this situation, the government is going to take a decision to withdraw the incentive from the PPP.

However, in the case of those who have already received various benefits, including this tax holiday, it will continue.

When asked, PPP Authority Director General Farooq Ahmed told Prothom Alo that incentive facilities will be available for ongoing projects.

However, private sector businessmen have disagreed with this decision.

The private sector invests there at risk. now. The government implements the interesting projects with its own money. And those that are unimportant projects, they do in the PPP model. This is also the reason why no one wants to invest in PPP.

For this reason, the PPP authorities are moving away from the previous decision.
