The American Space Agency’s “Parker” solar orbiter, which set out on the path of the Sun in 2018, set two records in one day. He became the spacecraft that came closest to our star and flew at a speed that no spacecraft has managed to reach so far.
One of the most ambitious missions in the history of human space exploration, NASA’s solar probe “Parker”, almost touched the Sun on April 29, ie it passed just over 10 million kilometers from its surface. When it came closest, it was racing at a speed of about 150 kilometers per second in relation to the Sun, that is, it was flying faster than any spacecraft so far.
For example, “Parker” flew at a speed of about 0.05 percent of the speed of light, and at this speed it would be able to make a circle around the Earth in four and a half minutes or it would reach the Moon from the Earth in 40 minutes.
However, the “Parker” mission is not over yet. The passage of the probe next to the Sun is only the eighth of the planned 24 passes until the end of the mission in 2025.
In the closest passage next to the Sun, the probe should approach a little less than seven million kilometers, which is about six times closer than the “Helios” probe, which crashed in 2018, succeeded.
Precisely due to the proximity of the Sun, the speed of the probe is increasing, and the maximum should be around 200 kilometers per second.
The Parker solar probe measures magnetic fields and monitors the flow of energy within the Sun. The data it collects should help experts understand how our star emits energy particles that make up the solar wind, as well as solve the mystery of why the surface layer of the Sun is warmer than the inner layers.
