NASA launched a space probe early Sunday that will go closer to the Sun than any spacecraft before, the agency announced.   


 The craft will endure extreme heat while zooming through the solar corona to study the Sun’s outer atmosphere that gives rise to the solar winds. The Parker Solar Probe, a spacecraft the size of a small car, launched from Cape Canaveral in Florida about 3:30 a.m.  Sunday, on a seven-year mission. It is set to fly into the Sun’s corona within 3.8 million miles (6.1 million km) of the solar surface, seven times closer than any other spacecraft.  NASA hopes the findings will enable scientists to forecast changes in Earth’s space environment.   


 The probe, named after American solar astrophysicist Eugene Newman Parker, will have to survive difficult heat and radiation conditions. It has been outfitted with a heat shield designed to keep its instruments at a tolerable 85 degrees Fahrenheit (29 degrees Celsius) even as the spacecraft faces temperatures reaching nearly 2,500 degrees Fahrenheit (1,370 degrees Celsius) at its closest pass.
