After an unsuccessful attempt on the eve of NASA still launched a solar probe Solar Probe Parker. It is the first spacecraft that will fly at a record close distance from the Sun and will study the processes occurring at the border of the crown and the atmosphere.
According to information on the NASA site, the probe was launched on a Delta IV Heavy rocket today, August 12, at 10:31 Moscow time from Cape Canaveral in the U.S. state of Florida.
It is expected that the device, the creation of which was spent 1.5 billion dollars, will be released a stable orbit around the Sun at the end of 2024 and close to the stellar surface at a distance of 6.4 million km seven times closer than ever.
This means that the Parker Solar Probe will be within the crown of the Sun, that is the outer layers of its atmosphere where temperatures can reach 500 thousand Kelvin (500 degrees Celsius) and even several millions of Kelvins.
Notably, on Board unit is installed devices for measuring electromagnetic field strength of the Sun and determining the characteristics of particles emitted by the star. This will allow you to answer questions about the interaction of the solar corona from the photosphere, the upper layer of the Sun, to understand how the emerging and dispersed particles of the solar wind.
We note, initially, the launch of solar probe was scheduled for 11 August, but for a few minutes before the start was postponed for an hour, and then it was rescheduled for the day. The Agency explained that there have been violations of limit is run, and then in the opening window, no time left to run.
Yesterday we also watched the fifth Eclipse of 2018, which was the most visible Eclipse of the Sun this year and shut down a large “corridor of eclipses”, which was launched in January.
