Parker Solar Probe Beams Red Data from Solar Corona

NASA Parker Solar Probe sets a record when it was launched at the beginning of this year as the fastest ever spacecraft in history with a maximum speed of around 430,000 miles per hour. However, no history has been made. Parker has already completed the first sunshine flight, and NASA says that the early execution of the probe is all that the team could hope for.

Parker is an important step in NASA, which in decades wanted to study coronation in the sun. However, technology for protecting the probe in this environment did not exist until recently. It is anti-naive, but the ionized plasma crown around the sun is much hotter than the surface of the stars themselves. According to NASA estimates, the corona has about one million Kelvin, 300 times hotter than the surface.

NASA developed an improved thermal display consisting of a 4.5-inch carbon composite foam between two carbon fiber sheets to maintain Parker's safety, but it was not possible to know precisely how it will work until the probe reaches our local star. A scientist at the Parker Solar Probe project, Nour Raouaf, a Johns Hopkins University Parker, claims that the spacecraft performs "better than expected" after the first through corona.

Parker took place through the coronal from October 31 to November 11. The researchers were delighted to see Parker staying in transit in the same plasma pocket for several days, which means it can get more data than we can on Earth. As the sun rotates, the gap around it is pulled out with it, so over time, remote monitoring of structures is complicated. The heat screen that kept Parker from melting also interferes with data transmission, so Parker will take one more orbit to return all of the new data.

NASA will need time to understand all the data from Parker. The team hopes to learn more about how the solar magnetic field works, and now its weather conditions can affect the Earth. However Parker has already sent some cool images. This image, taken with the WISPR instrument, shows a coronal rendering of mercury, which is seen as a vivid point. NASA plans to report the next pass of the probe in April 2019. Parker plans to make 24 passes through the corona, reaching 3.8 million miles from the surface.
