Is it true that the U.S. super-pressure balloon broke the flight record?

On July 3, NASA announced that the U.S. super-pressure balloon project had completed its second test. It flew from New Zealand to Peru and successfully circled the earth in 14 days. NASA's goal is to fly for 100 days. The total duration of this flight exceeded 46 days. Although it did not reach the goal, the 46-day flight time has broken the flight record. About the American super-pressure balloon

What kind of balloon is the American super-pressure balloon? In layman's terms, it means very large, extremely large, with a total volume of 18 million square feet and a diameter of 114m. Flying at an altitude of several kilograms of the ozone layer is already an innovation in history. Ordinary balloons will change their flight altitude as the sun changes, but this super-pressure balloon uses pressurized helium, which can solve the problems caused by the sun and extend the flight time in the air. However, even if there are no problems caused by solar radiation, the test effect will still be reduced due to the cold air currents in the high altitude, so the test had to be terminated early. Limitations of super-pressure balloons

There are certain limitations in observing the flight conditions of super-pressure balloons. Relevant physicists pointed out that although observers will study a large amount of data, in order to obtain super-pressure balloons It is still difficult to squeeze all the data on the balloon. And due to differences in altitude and temperature, superpressure balloons have so far not been able to prove the reliability of the data obtained. At this point, there is still a lot of room for development in the observation of super-pressure balloons in the future, and it will definitely bring more and more accurate data to the project. The applicability of super-pressure balloons

Super-pressure balloons can fly for long periods of time, indicating that they are likely to replace satellites and become a low-cost observation alternative. When scientists tested the superpressure balloon for the second time, they installed a spectrometer that could detect gamma rays. They used the spectrometer to receive low-frequency sounds in the sky. Sounds that were inaudible on the ground sounded louder in the air. It will be obvious that this is of great significance to scientists studying volcanoes, earthquakes, etc.
