Researchers from around the world want to collaborate with UAH so that they can engage in the excitement of the PSP research that will be undertaken for the next 5-6 years, Dr. Zank says.

"This kind of discovery science is extraordinarily exciting and satisfying and PSP is definitely one of the highlights of my professional career. The new paper is one of four published by Nature.

"Besides being important in presenting the first PSP results, these results are also – for now – a report of in situ plasma, magnetic and electric fields, dust, and radio burst measurements made during the closest excursion to the sun ever.".

First Parker Solar Probe scientific papers are published in Nature.

In the early hours of Aug. 12, 2018, NASA’s Parker Solar Probe blasted off from Cape Canaveral Air Force Station atop a United Launch Alliance Delta IV on its audacious journey to the Sun.

UAH provided detailed and extensive theoretical background in developing the SWEAP proposal for the NASA mission, which launched Aug. 12, 2018, and completed its first solar orbit on Jan. 19, 161 days after it left Florida’s Cape Canaveral Air Force Station.

A second surprise is that long-duration and isolated velocity spikes with large rotations in magnetic field were seen in the first perihelion, the point at which PSP was closest to the sun. The Faraday cup for the SWEAP instrument suite was designed, created and tested by a partnership between UAH, NASA’s Marshall Space Flight Center (MSFC) and the Smithsonian Astrophysical Observatory (SAO) to sample solar wind while directly exposed and traveling closer to the sun than spacecraft have ever been. The probe will continue to study our star until 2025, creeping ever closer to the visible surface and, in turn, deeper into the solar wind, the constant outflow of highly charged plasma that stretches across the solar system.

"The agreement between the model and observations is extremely promising, but of course we're still looking at data that is some distance from the lower corona, so this is a project that will continue to evolve.".

Closer to the solar wind's source, Parker Solar Probe saw a much different picture: a complicated, active system.

The set of papers, published as a supplement series to The Astrophysical Journal, includes some findings that have already been publicized after presentations at scientific conferences.

"It is exciting that in this field, as well as others, we're one of the leading institutions to do science that will hopefully solve several of the most outstanding unanswered questions that have puzzled us for the last 50 years.".

Some of Parker Solar Probe's measurements are bringing scientists closer to answers to decades-old questions. "Now, I've gotten used to it.

Our solar system is awash in dust—the cosmic crumbs of collisions that formed planets, asteroids, comets and other celestial bodies billions of years ago. "The large rotational flow of the solar wind seen during the first encounters has been a real surprise," said Kasper.

On 4 December 2019, the first four research papers were published describing findings during the spacecraft's first two dives near the Sun. The content is provided for information purposes only. This is a bit like children riding on a playground park carousel—the atmosphere rotates with the Sun much like the outer part of the carousel rotates, but the farther you go from the center, the faster you are moving in space.

She has established that there are two classes of turbulence, one associated with the so-called slow solar wind and comprised primarily of small-scale flux rope structures, whereas fluctuations in the so-called fast solar wind are comprised mainly of outwardly propagating Alfven waves. Dr. Zhao's paper focuses on establishing the nature of the sun’s magnetic field and velocity field fluctuations and what kind of turbulence they represent.

Four research papers based on Parker Solar Probe data have been published in the journal Nature.

The UAH team is one of the elite space plasma theory, modeling and data groups in the world, Dr. Zank says.

Parker Solar Probe Mission Releases Science Data from Fourth Orbit Just over a month after Parker Solar Probe marked two action-packed years in space — and hot on the heels of its third Venus flyby and fifth solar orbit — the mission to “touch” the Sun released another trove of data to the public on Sept. 15. "Waves have been seen in the solar wind from the start of the space age, and we assumed that closer to the Sun the waves would get stronger, but we were not expecting to see them organize into these coherent structured velocity spikes," said Justin Kasper, principal investigator for SWEAP—short for Solar Wind Electrons Alphas and Protons—at the University of Michigan in Ann Arbor. Solar scientist Eugene Parker is the first living namesake of a spacecraft. Soon, Parker Solar Probe will have company in its close-up study of the sun: NASA and the European Space Agency are launching a mission called Solar Orbiter on Sunday (Feb. 9).

"Many of our ideas for explaining the primary science goals of PSP are the currently leading theories, and so PSP gives us an unparalleled opportunity for possibly confirming or extending these ideas and models," he says.

The Faraday cup for the SWEAP instrument suite was designed, created and tested by a partnership between UAH, NASA’s Marshall Space Flight Center (MSFC) and the Smithsonian Astrophysical Observatory (SAO) to sample solar wind while directly exposed and traveling closer to the sun than spacecraft have ever been.

Future US, Inc. 11 West 42nd Street, 15th Floor, The new paper is one of four published by Nature. Our image of the day, NASA to announce 'exciting new discovery' about the moon today. Scientists have long suspected that, close to the Sun, this dust would be heated to high temperatures by powerful sunlight, turning it into a gas and creating a dust-free region around the Sun. At closest approach (called perihelion) on Sept. 27, Parker Solar Probe came within about 8.4 million miles (13.5 million kilometers) of the Sun’s surface — less than one-tenth of the distance between Earth and the Sun — while reaching a top speed of 289,927 miles per hour (466,592 kilometers per hour), breaking its own records for speed and solar distance.

What is Parker Solar Probe?

These measurements confirm the hypothesis that Alfvén waves are the leading candidates for understanding the mechanisms that underlie the coronal heating problem.

Four research papers based on Parker Solar Probe data have been published in the journal Nature.
