Notwithstanding the recent failed attempt, NASA still launched the Parker Solar Probe. This is the first spacecraft that will fly at the record close range from sun and study processes at the heliosphere and atmosphere. 
According to the information on the website of NASA, the probe was launched on Delta IV Heavy rocket from Cape Canaveral in the State of Florida, the USA, today, on August 12 at 10:53 a.m. Kyiv time.  

It is believed that the $1.5 billion spacecraft will enter on a stable orbit around the sun in the end of 2024 and will get to the surface of the star on the distance of 6.4 million km. It is seven times closer than ever.  
It means that the Parker Solar will be at the heliosphere i.e. at its atmosphere slices where the temperature reaches 500 thousand Celsius. 
It is noteworthy that the equipment for measuring electromagnetic field intensity of the sun and for identification particles emitted by the star. It would allow finding answers for questions about the interaction of heliosphere with photosphere, the upper layer of the sun, to understand how the particles of the solar wind are generated and dispersed. 

Initially, the launch of the probe was scheduled for August 11 but it was postponed for one hour, a couple of minutes prior to the expected launch time. Later the launch was postponed for 24 hours. 
The agency explained that there were irregularities of the launch limit and the launch window didn’t have time left to run.
