The observations and data could provide insight about the physics of stars, change what we know about the mysterious corona, increase understanding of solar wind and help improve forecasting of major space weather events. Those events can affect satellites and astronauts as well as the Earth -- including power grids and radiation exposure on airline flights, NASA said.Solar wind is the flow of charged gases from the sun, present in most of the solar system. It screams past Earth at a million miles per hour, and disturbances can cause disruptive space weather that impacts our planet.Surveys by the National Academy of Sciences have estimated that a solar event with no warning could cause trillion in damage in the United States and leave parts of the country without power for a year.The mission's objectives include "tracing the flow of energy that heats and accelerates the sun's corona and solar wind, determining the structure and dynamics of the plasma and magnetic fields at the sources of the solar wind and explore mechanisms that accelerate and transport energetic particles."Four suites of instruments will gather the data needed to answer key questions about the sun. FIELDS will measure electric and magnetic waves around the probe, WISPR will take images, SWEAP will count charged particles and measure their properties, and ISOIS will measure the particles across a wide spectrum.But what part of this mission will "touch" the sun? The Solar Probe Cup, dubbed "the bravest little instrument," is a sensor that will extend beyond the heat shield to "scoop up samples" of the sun's atmosphere, according to Justin Kasper, mission principal investigator and professor of climate, space sciences and engineering at the University of Michigan. The cup will glow red when the probe makes its closest approach to the sun, sampling the solar wind and effectively touching the sun."The Alfvén point is the distance from the Sun beyond which the charged particles that make up the solar wind are no longer in contact with the surface of the Sun," Kristopher Klein, co-investigator for the probe and University of Arizona Lunar and Planetary Lab assistant professor, said in a statement. "If the Parker Solar Probe can reach below the Alfvén point, then we can say the spacecraft has entered the solar atmosphere and touched the Sun."The probe will be close enough to watch solar wind whip up from subsonic to supersonic. It will also pass through the origin of the solar particles with the highest energy."It will provide us with a better understanding of the environment the Earth is in," Klein said. "Our ability to forecast space weather is about as good as our weather forecasts were in the 1970s. If you have a better understanding of the behavior of these solar energetic particles, then you can make better predictions about when to send astronauts to Mars or protect a satellite before it gets ripped apart by a radiation burst."The mission is scheduled to end in June 2025. The first data download from the Parker Solar Probe is expected in early December, after the probe reaches its first close approach of the sun in November."Eventually, the spacecraft will run out of propellant," said Andy Driesman, Parker Solar Probe project manager at the Johns Hopkins Applied Physics Lab. "The way I like to think about it: In 10 to 20 years, a carbon disk will be floating around the sun in orbit, and it will be around until the end of the solar system." 3473

The obvious places to look would be around these chemical plants and the refineries, said Walker. "But also the places where they use these chemicals. Paint and body shops, definitely, print shops, gas stations -- they have tanks of gasoline underground, huge tanks of it -- we always hear about dry cleaners, of course," said Walker. 334

The growing resentment has also been a springboard for partisan political attacks, with opponents of Macron's centrist En Marche party attempting to energize their bases to fuel further revolt."This government hasn't understood the anger of the French," Olivier Faure, head of the French Socialist Party, said Wednesday."Macron has not heard the French," Laurent Wauquiez, leader of the center-right party Les Républicains, added in an interview for BFMTV and RMC radio.Meanwhile, Macron's former nemesis, Marine Le Pen, leader of France's far-right National Rally, said: "We were the first party to express our total support for this movement."Castaner hit back at Macron's opponents, branding the protests "political" and accusing Les Républicains of being behind them."It's a political protest with the Republicans behind it, and it's irrational because the rising taxes have been compensated by the decline in the oil market," he told CNN's French affiliate BFMTV. "We hear the protests, we hear the anger, I know the situation, but we have to explain that it's essential that we exit fossil fuels."The minister said police would be present to break up any dangerous roadblocks. "I am asking for the roads to not be completely blocked," Castaner said. "Where there is a roadblock -- which means there's a risk for emergency services -- there will be police."Macron struck a more conciliatory tone in an interview Wednesday, saying: "I hear the anger, and it's a fundamental right in our society to be allowed to express it."He nevertheless admitted that he was "wary because many different people are trying to piggyback on this movement."Prime Minister Edouard Philippe also announced close to 500 million euros in aid to low-income motorists in a key concession Wednesday. 1778

The most significant grip on power that Wisconsin Democrats have is Sen. Tammy Baldwin's seat.She'll face the winner of a Republican primary Tuesday that pits state Sen. Leah Vukmir, a darling of conservative talk radio who has the backing of Walker and the state GOP's establishment, against businessman and veteran Kevin Nicholson.What's unusual about the race is that Illinois businessman Richard Uihlein has pumped nearly million into groups supporting Nicholson -- making for a highly unusual tie between a politician and his corporate benefactor.Baldwin has held a clear lead in recent public polls, but Republicans have long believed that the Walker-built political machine and the state's rightward drift could make her a surprisingly ripe target in November. 771

The Gwinnett County Police Department said in a news release Tuesday the victims were 15-year-old Devin Hodges and 17-year-old Chad Carless. 140
