Scientists report that within the next seven years the device will become closer solar orbit in 2024 should be approximately 3,83 million kilometers from the target.
Parker will face "brutal" heat and radiation during the epic journey that will take it to within 3.83 million miles of the Sun's surface, according to the space agency.
The previous record for closest solar approach was set by the German-American Helios 2 spacecraft in April 1976.
This week, the probe will get 15 million miles away from the sun. After that, the probe will burn up in the sunlight.More news: Lakers falter again in the stretch, losing to Minnesota 124-120
Seven hours later the probe had reached a speed of 69.72 km/s (kilometres per second, which translates to around 250,992 km/h or 155,959 mph) relative to the Sun. Along with this, gaining momentum from the sun's powerful gravity, the probe will accelerate at a top speed of close to 690,000 km/hr.
The previous record belongs to the spacecraft Helios 2, which was jointly developed by Germany and the USA. Even the massive Delta IV Heavy (above) that launched the Parker Solar Probe on 12 August 2018 falls well short. Perihelion - nearest to the Sun point of the orbit - for the first time reaches 5 November.
Parker Solar Probe close to the Sun less than 42,73 million kilometers. "It's a proud moment for the team, though we remain focused on our first solar encounter". The probe is now in the process of aligning itself into an elliptical orbit that will enable studies of the solar wind near its source. The Parker Solar Probe is expected to best that today as well, reaching higher speeds at about 10:54 p.m. EDT (0254 GMT on October 30), NASA officials said.
To learn as much as it can about the solar winds, Parker needs to get as close as possible to these eruptions.
