Tthe sun's cry looks like a crazy dream. But the technology that meets the 60th anniversary of the popularity of the local eye, NASA's Parker Solar Probe shows that dreams really come true.
Johns Hopkins' Applied Physics Laboratory, which was launched in August in August, broke two books on Monday. First was the shortest distance the spacecraft had ever fired in relation to the sun, and secondly the speed faster than any spacecraft in history.
The Parker Solar Probe was only 26.55 million kilometers (42.7 million kilometers) because it reached the closest orbital route to the sun – called the perihelion – at 10:28. Eastern Monday night, hurtling is an unprecedented 213,200 miles an hour to collect scientific information.
But this record is just the first of many, the meter breaks when Johns Hopkins APL's project manager Andrew Driesman explains the video published in the news magazine.
"Closer to the Sun than any Other Spacecraft"
"We're going to get closer to the sun than any other spaceship has gone before. We're not going to do it once, we're not going to do it twice – we do it 24 times and it's horrible."
At first encounter, the car-sized probe passed 26.55 million kilometers from the sun's surface, which is already comparable to the predicted record of Helios 2 in 1976 to just under 27 million kilometers. During the next seven years, the probe uses Venus gravity to get closer and closer to loops. It is planned to fall to 3.8 million miles from the surface by the end of the mission in 2025.
But in hell temperatures and intense radiation, scientists are looking forward to exploring solar magnetic fields, plasma, and energetic particles. This close to the sun brings Parker Solar Probe directly to the sun, an atmosphere around the sun that reaches 2,500 degrees Fahrenheit (or 1,337 degrees Celsius), exceeding the surface temperature itself.
It's hot here
To overcome heat, a spacecraft protects the sun by means of thermal protection called Thermal protection system. The name of its low creativity undermines how powerful this part of the probe is. A 160-pound shield, a 4.5-inch thick foam body set between the superheated carbon composite, has a high thermal resistance that it can withstand 820 degrees Fahrenheit and keeps the equipment behind it safely at room temperature.
The thermal shield system allows heat to force researchers to keep communication simple. Four different light beats confirm that everything is OK, while the other three show different types of things. However, during the days around the Perhelillion, solar radio emissions cut off messages until the spacecraft can sound.
"We have managed to reach the spacecraft without encountering, so the only thing that we have is the beacon sounds," says Sanae Kubota, vice director.
Using information – which takes approximately 30 minutes for sending between a probe and a country – researchers are trying to better understand space wind like solar winds. While the sun is 92.96 million miles, space weather affects both astronaut instruments and people on Earth by throwing away satellites, including GPS systems.
For the fastest spacecraft, the scientific information the probe collects can not come fast enough. As the spaceship is directed to the sun, scientists have to wait several weeks before the data can be sent back to Earth.
