The instrument WISPR of the mission Parker Solar Probe NASA saw the solar wind pass during the first solar encounter of the spacecraft in November 2018.
The spacecraft, launched a year ago and that on its orbital journey approaches our star more than any previous one, carries four sets of scientific instruments to collect data on particles, solar wind plasma, electric and magnetic fields, solar radio broadcasts and the structures in the hot outside atmosphere of the Sun, the crown. This information will help scientists unravel the physics that drives extreme temperatures in the corona, which is counterintuitively hotter than the solar surface below, and the mechanisms that drive particles and plasma into the solar system.
The WISPR instrument of Parker Solar Probe it captures images of solar wind structures as they leave the Sun, allowing scientists to connect them with the on-site measurements of the Parker's spacecraft of their other instruments.
A new video, which runs from November 6 to 10, 2018, combines views of both WISPR telescopes during the first solar encounter of Parker Solar Probe.
The Sun is out of frame beyond the left side of the combined image, so the solar wind flows from left to right beyond the view of the telescopes. The bright structure near the center of the left edge is what is known as a streamer, a relatively dense and slow solar wind flow from the Sun, which originates near the equator of the Sun.
The video seems to accelerate and slow down throughout the film due to the ways in which data is stored at different points in the Parker solar probe's orbit. Near the perihelion, the closest approach to the Sun, the spacecraft stores more images, and more frames for a given section make the video seem to slow down. These images have been calibrated and processed to eliminate background noise.
The galactic center of the Milky Way It is visible on the right side of the video. The planet visible on the left is Mercury. The fine white stripes in the image are dust particles that pass in front of the WISPR cameras.
The mission team is currently in the process of analyzing data from the first two orbits of Parker Solar Probe, which will be presented to the public in 2019.
"The data we are seeing from the instruments of Parker Solar Probe they show us details about solar structures and processes that we have never seen before, "said Nour Raouafi, a Parker Solar Probe project scientist at the Johns Hopkins Applied Physics Laboratory, who built and operates the mission for NASA:" Fly near the Sun, a very dangerous environment, is the only way to get this data, and the spacecraft is working with great success.
