The first approach to the Mission Sun will take place in early November 2018, but even now, still outside of Venus' orbit, the instruments indicate that they are ready to collect measurements of what is happening in the world. solar wind.
"All the instruments returned data that serve not only to calibration, but also to what we expect from them near the Sun to solve the mysteries of the solar atmosphere, the crown," explains Nour Raouafi, Parker Solar Probe project scientist. Laboratory of Applied Physics, Johns Hopkins University, Laurel, Md.
WISPR, the only embedded imager of the mission, captured the first shots of his trip to the Sun on September 9, 2018. Similarly, the FIELDS suite of instruments provided the first observations of magnetic fields and even captured a burst of radio waves burst.
One of the SWEAP instruments sampled its first solar wind gust and the ISʘIS instrument – pronounced "ee-sis" and including the Sun symbol in its acronym – has successfully measured the environment of energy particles.
The first GOLD lamp closely followed the Parker Solar Probe. On September 11, the GOLD, a short – term instrument for world – wide record and disc observations, went live and opened its cover to digitize the Earth for the first time.
In this length of light wave invisible to the human eye, GOLD allows researchers to visualize temperature and composition on a global scale in the dynamic region where the upper Earth 's atmosphere meets the Earth' s. ;space.
The commissioning of GOLD began on September 4 and will continue until early October, while the team continues to prepare the instrument for its two-year scientific mission.
"The GOLD mission is changing the game by providing unparalleled images of the world's top weather conditions, similar to the first ever Earth's weather satellites," said Sarah Jones, NASA's Goddard Space Flight Center GOLD mission scientist in Greenbelt, Maryland. .
"These global-scale images of the Earth-space boundary will allow scientists to begin to unravel the effects coming from the Sun compared to those from the Earth's climate below."
With missions both near and far, like bookends in the vast space between the Sun and the Earth, researchers are eager to fill the gaps in our understanding of the complex relationship between solar activity and the conditions on Earth.
Historically difficult to observe, the studies of the GOLD region are little understood and can undergo dramatic changes in less than an hour. GOLD, which occupies a geostationary orbit and overflies 22,000 miles over the Western Hemisphere, will provide hour-by-hour updates on the changing conditions of near-Earth space, known as space weather.
Changes in space weather can blur communication signals, disrupt electronics on satellites, endanger astronauts and, at worst, disrupt power grids.
Meanwhile, Parker Solar Probe will visit the flaming crown, closer to the sun than any other spacecraft before. The mission seeks to answer fundamental questions about the Sun – questions that underlie the understanding of how solar activity shapes spatial weather through the solar system.
TESS is NASA's astrophysical exploration mission led and operated by MIT in Cambridge, Massachusetts, and managed by Goddard. Dr. George Ricker of the Kavli Institute for Astrophysics and Space Research at MIT is the principal investigator of the mission. Additional partners include Northrop Grumman, based in Falls Church, Virginia; NASA's Ames Research Center in California's Silicon Valley; the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts; Lincoln Laboratory of MIT in Lexington, Massachusetts; and the Science Telescope Science Institute in Baltimore. More than a dozen universities, research institutes and observatories around the world participate in the mission.
Parker Solar Probe is part of NASA's Living with a Star program, which explores aspects of the Sun-Earth system that directly affect life and society. The LWS is managed by Goddard for the Heliophysics Division of the NASA Science Missions Directorate in Washington. Johns Hopkins APL manages the Parker Solar Probe mission for NASA. APL designed, built and operates the spacecraft.
GOLD is an opportunity mission of NASA as part of the heliophysical exploration program. Goddard manages the exploratory program of the heliophysical division of NASA's Science Mission Directorate in Washington. It is designed to provide frequent and inexpensive access to space using the principal scientific research conducted by the investigator in the field of astrophysics and heliophysics.
GOLD is headed by the University of Central Florida. The Atmospheric and Space Physics Laboratory at the University of Colorado at Boulder built and operates the instrument. The GOLD instrument is hosted on a commercial communication satellite, SES-14, built by Airbus for the Luxembourg satellite operator SES.
