Nasa: Approves heliophysics missions to explore the sun – Science – Life



NASA has approved two heliophysics missions to explore the #Sun and the system that drives space weather near #Earth. #Together, NASA’s contribution to the #Epsilon #Mission of the #Extreme #Ultraviolet #High #Performance #Spectroscopic #Telescope, or EUVST, and the #Electrojet #Zeeman #Image #Explorer, or EZIE, will help understand the #Sun and #Earth as an interconnected system.

#Understanding the physics that drive the solar wind and solar flares, including solar flares and coronal mass ejections, could one day help scientists predict these events, which can affect human technology and explorers in space, he says. the NASA statement.

The #Japan #Aerospace #Exploration #Agency (JAXA) leads the #Epsilon #Mission of the #Extreme #Ultraviolet #High #Performance #Spectroscopic #Telescope (EUVST) (#Mission #Solar-C EUVST), along with other international partners. The EUVST, scheduled to launch in 2026, is a solar telescope that will study how the solar atmosphere releases solar wind and drives eruptions of solar material.

#According to the statement, these phenomena propagate from the #Sun and influence the space radiation environment throughout the solar system. #Nasa’s hardware contributions to the mission include an intensified UV detector and supporting electronics, spectrograph components, a guide telescope, software, and a cut jaw imaging system to provide context for spectrographic measurement.

The budget for NASA’s contributions to EUVST is $ 55 million. The #Principal #Investigator for #Nasa’s contribution to EUVST is #Harry #Warren at the #United #States #Naval #Research #Laboratory, in #Washington.

The #Electrojet #Zeeman #Imaging #Explorer (EZIE) will study the electrical currents in #Earth’s atmosphere that link the aurora with #Earth’s magnetosphere, a piece of #Earth’s complicated space weather system that responds to solar activity and other factors. .

The #Auroral #Electrojet (AE) index is a common measure of geomagnetic activity levels, although the details of the structure of these streams are not understood. EZIE will launch no earlier than #June 2024.

The total budget for the EZIE mission is $ 53.3 million. The mission’s principal investigator is #Jeng-Hwa (#Sam) #Yee of the #Applied #Physics #Laboratory of the #Universidad #Johns #Hopkins en #Laurel, #Maryland.

“#We are excited to add these new missions to the growing fleet of satellites that are studying our #Sun-Earth system using an astonishing array of unprecedented observing tools,” said #Thomas #Zurbuchen, associate administrator for science at NASA #Headquarters at #Washington.

“In addition to my enthusiasm for selecting a pioneering multipoint observatory focused on auroral electroinjectors, I am particularly excited to follow the success of the #Yohkoh and #Hinode solar science missions with another international collaboration with JAXA and other #European partners at EUVST. “

The EUVST mission addresses the recommendations of a final #July 2017 report delivered by the #Multi-agency #Next #Generation #Solar #Physics #Mission #Science #Targets #Team. EUVST will take comprehensive UV spectroscopy measurements of the solar atmosphere with the highest level of detail to date, allowing scientists to determine how different magnetic and plasma processes drive coronal heating and energy release.

“#We are excited to work with our international partners to answer some of our fundamental questions about the #Sun,” said #Nicky #Fox, #Director of the #Heliophysics #Division at NASA #Headquarters in #Washington. “The EUVST observations will complement our current missions to give us a new perspective on our star.”

EZIE is an investigation comprising a trio of #CubeSats that will study the source and changes in the auroral electrojet, an electrical current that circulates through the #Earth’s atmosphere about 60-90 miles above the surface and extends to the magnetosphere. from the earth. The interaction of the magnetosphere and the solar wind compresses the side of the magnetosphere that faces the #Sun and drags the night side of the magnetosphere towards what is called a “magnetic tail.”

#Auroral electrojets are generated by changes in the structure of the magnetic tail. The same space weather events that power the beautiful aurora can cause interference with radio and communication signals and utility networks on the #Earth’s surface, and damage orbiting spacecraft.

“#With these new missions, we are expanding the way we study the #Sun, space and #Earth as an interconnected system,” said #Peg #Luce, deputy director of the #Division of #Heliophysics at NASA #Headquarters in #Washington.

“EZIE’s use of proven instrument technology in #Earth science #CubeSat missions is just one example of how science and technology development at NASA go hand in hand across disciplines,” says #Luce.

#Funding for these opportunity missions comes from the #Heliophysics #Explorer #Program, administered by the #Explorer #Program #Office at NASA’s #Goddard #Space #Flight #Center in #Greenbelt, #Maryland.
