The mission will tackle some of the sun's biggest mysteries.
, ISRO officials say. Flares are powerful flashes of high-energy radiation, and CMEs are huge eruptions of solar plasma.
Both types of outburst can affect us here on Earth. Intense CMEs that hit our planet, for example, trigger geomagnetic storms that can disrupt satellite navigation and power grids. Aditya-L1 will also tackle the"coronal heating problem," one of the biggest mysteries in heliophysics. The corona — the sun's wispy outer atmosphere — is incredibly hot, reaching temperatures around 2 million degrees Fahrenheit , That's about 200 times hotter than the solar surface, which is"only" 10,000 degrees F or so. It's still unclear what is responsible for this startling and counterintuitive discrepancy.
Aditya-L1 has other science goals as well. For instance, the mission also aims to more fully flesh out the , the stream of charged particles flowing constantly from the sun, ISRO officials said. Aditya-L1 will measure the composition of the solar wind and attempt to determine how it is accelerated.
