NASA launched the Parker Solar Detector last year as part of its mission to study the Sun. The spacecraft already has the closest record to the Sun, and as it orbits closer and closer to the stars, it will repeatedly refresh this record in the next few years. If everything goes according to plan, the Parker detector will be less than 9.86 times the sun's radius from the sun's surface in 2025.

According to NASA, the second close contact occurred at 6:40 pm EST on April 4, when the space agency said the speed of the detector was 213,200 mph. The team that manages the Parker Solar Detector reported that during this close proximity approach, the spacecraft issued an "A" beacon state, which means that it is still in good operating condition despite high temperatures.

Before the second flight, the Parker Solar Detector's status recorder was cleared and the previous data was sent to the Earth team. A range of instruments on the spacecraft enable it to collect general data about the sun and physics.

The detector must withstand extremely high heat during its mission, which is achieved by a large heat shield, which helps protect sensitive drill bits. The software enables the spacecraft to keep its heat shield facing the sun, ensuring it is not exposed to heat without protection. In addition, the device also has a liquid cooling system.
