  • Ingenuity helicopter makes flight on Mars

     

    In a historic event, for the first time, a helicopter flew over the Mars airspace. NASA's helicopter weighs just over 1.8 kg. It flew three meters or ten feet above the surface of Mars and even though it might not sound like a big deal but it is a huge deal and a first in the known history of Mars. Images of the flight were received by the ground control room several hours later as the data was to cover a distance of 176 million miles. The scientist community throughout the world has hailed this development as a breakthrough in the journey to Mars.

    The helicopter that flew over Mars is called Ingenuity. It flew on an automated system under a pre-installed flight program. The helicopter is also fitted with a navigation system, which brings it back to takeoff after the flight.

    The flight is only possible with a pre-installed flight program because it takes fifteen minutes to reach a message from earth to Mars and vice versa. During the flight, the helicopter made a full circle and then successfully landed in a valley-like area, which has been named 'Jezero Crater'.

    Helicopter flight images were also captured by the spacecraft's camera, which is currently on the surface of Mars. The spacecraft arrived on the Red Planet on February 18 this year after a long journey. The spacecraft is called the Preservation Rover. The spacecraft was parked about 76 feet from the helicopter's flight site. NASA has indicated that video of the helicopter's flight will be received on the ground in the next few days.

  • Early or late marriages: what do the psychologists say?

     

    Marriage is a bond between two persons that strengthens their relationship and gives them a sort of closure. Due to various reasons, some people get married early while some people get married late.

    Elder people often believe that the marriage of girls should be done at an early age. Even so some believe that as soon as a girl attains adulthood, she should ba married off. However, do you know what psychologists say about this topic?

    According to the Bright Side website, late marriage leads to more happiness, and the biggest reason for this is the development of maturity which leads to understanding. If you look at the divorce rate, most of the couples who get divorced are those who are younger.

    Psychologists have a kind of consensus that marriage better off when it's done at a bit later stage because the couple has a greater ability to understand each other.

    If the girl is young then it is important that the boy is mature to avoid any kind of problems. Otherwise, the issue of compatibility soon kicks in and creates a plethora of problems. 

    Mature people know very well how to fulfill their responsibilities in an efficient way. So the bottomline is to get married when the couple is mature enough to take on the responsibilities that the marriage places on the couple.

  • Reason and cure for headache while fasting

     

    Many people are familiar with the throbbing headache they experience while fasting in the month of Ramzan. For some people, this pain increases to such an extent that it causes vomiting and also leads to the fear of losing the fast. However, despite all the advancements in the field of medicine, experts have not been able to say anything definitive about the causes of headaches due to fasting and are only offering hypotheses based on assumptions.

    So what are the possible reasons behind this headache and how can we get rid of it without breaking our fast? 

    Symptoms of fasting headaches

    The headache caused by fasting is towards the front of the forehead. It is not as threatening as the usual pain, but it is very severe in the head of migraine sufferers. People who suffer from recurrent headaches in normal life are more likely to have headaches due to fasting.

    Causes of headaches while fasting

    Hypoglycemia

    Usually, when a person does not eat for a long time, it causes his blood sugar level to fall below the normal level which can lead to headaches. However, according to experts, there can be no definitive reason to explain this phenomenon because most of the time, even when the blood sugar level is at a normal level, there can be a headache.

    Due to caffeine etc.

    Most of the people who are addicted to tea or any other kind of caffeine like smoking etc, are more likely to experience this headache during fasting time. Caffeine deficiency can also cause headaches.

    Due to lack of water

    Not drinking water for 14-15 hours can cause dehydration in the human body and it is a well-known fact that dehydration can increase the intake of nitrogenous substances which can lead to headaches.

    Treatment of headaches due to fasting

     

    To avoid this headache, it is better to get rid of tea and other intoxicants before Ramadaan. Also, take an adequate amount of water after Sahar and Iftar to take care of your diet. Keep it and keep it balanced. However, if the headache does not go away, you must consult a doctor.

  • Supersonic AS3 Plane: London to Newyork in around 2 hours

    No supersonic aircraft has been built for passengers since Concorde was abolished. Now a new test aircraft is ready, which is four times faster than the speed of sound.  With this plane, the journey from New York to London will take just two hours.

    The plane which is twenty-one meters long, is a small but a huge leap in the history of aviation. For the first time in history, there is now a privately built supersonic aircraft. So far, the European Concorde (up to 2003), the Soviet Union's Topolov Tu-144 (up to 1999) and supersonic military jets have all been developed with the cooperation of governments and military budgets.

    But this plane is different. The Denver-based company Boom Supersonic introduced the first purely privately produced supersonic jet in October 2020. This single-seat jet is currently called the XB-1BB Boom. This year, trials of the three-engine jet will begin in the desert in the US state of California.

    Three and a half hours from John F. Kennedy to Heathrow Airport

    The project aims to validate an aerodynamic concept and then mass-produce this supersonic jet, for at least 75 passengers. According to experts, commercial flights of such planes may start in the second half of this decade and their speed will be up to 2700 kilometers per hour, ie the journey using this supersonic plane from London to New York will be completed in three and a half hours.

    The company claims that the fuel for these aircraft will be environment friendly and will emit very little carbon dioxide as possible. The aircraft uses technology that will reduce the noise. Airplanes that make a lot of noise at start-up are currently banned. But in the United States, NASA and the Aviation Authority are continuing successful research to reduce the noise of supersonic aircraft.

     

    Flying faster than sound is a dream that has been seen for decades. In practice, this dream was first fulfilled by the manufacture of Concorde, but it still faces many challenges, such as the manufacture of the most suitable engines.

    The tireless work of many institutions continues

    Most likely, small supersonic jets will be developed first. For example, for business companies with a capacity of eight to fifteen people. Aion Supersonic has been working on it since 2002. So far, the company has not been able to bring a single supersonic jet to market, but recently the company introduced a model of the three-engine AS2 aircraft, which will be able to fly in the year 2024 and in the year 2026 it'll be able to take regular flights. However, the aircraft will be slower than Concorde.

    "We have a technology roadmap for the next 50 years," said Mike Mansini, Arien's then chief strategy and finance officer in 2019. The first step towards the future of the fastest journey will be with AS2.

    He said the next step would be to build a larger aircraft. "We will do all this keeping in mind the environmental requirements so that problems are minimized." Due to these problems, Concorde's capacity was also limited. It would be fair to expect the arrival of the first generation of new supersonic airlines in the 2030s. "

     Future AS2-Business Jet von Aerion possible from New York to London in two hours

    Earlier this month, just before Easter, Arion made an announcement. The company said it would make a big leap to the Supersonic AS3 by the end of this decade. The aircraft will have a seating capacity of 50 passengers and will be able to cover a distance of 13,000 km in a single flight. The speed of this supersonic plane will be 5000 kilometers per hour or possibly even higher. This will be the first time a commercial aircraft has reached the lower level of the 'hypersonic' range. Hypersonic begins with MacFive. Mac speed is a measure of how specific conditions are.

    However, very little information about AS3 has come to light. The company has promised to release more details of the project over the next few years. The company says the purpose of its aircraft is to reach any corner of the world within three hours.

    However, German researcher Bernd Leibhard is cautious. "In my opinion decades are left in the future of hypersonic," he says. Right now, supersonic speed is a very difficult task, and hypersonic speed would be a huge step beyond that. "
