The launch NASAParker Solar Probe, which for the first time in history to reach the Sun’s atmosphere, was postponed due to technical problems. About it reports NBC News.
Problems noticed in one minute and 55 seconds to launch, when the booster Delta-IV Heavy (developed by Boeing) Parker probe Solar Probe was ready for launch from Cape Canaveral. It is noted that the sudden discovery of problems associated with the missile. The start was moved to Sunday, August 12.
Parker Solar Probe will be the first spacecraft that will be able to “touch” the fiery corona of the Sun. The mission will last seven years.
As reported on the website NASA, the mission is to obtain new data on solar activity and measure the parameters of the solar wind. These data will allow scientists to better understand how the various processes in the Sun affect life on Earth, as well as predict a major coronal mass ejections and other major changes of space weather.
In order to reach the Sun, the probe uses the orbit of Venus and its gravity. Seven times it will fly past the planet to get to the desired rate. Parker Solar Probe will approach the Sun at a record distance of 3.83 million miles (or 6.16 million kilometers), also he will be able to approach the orbit of mercury, at a distance seven times less than was possible with other probes.
The device will move at a speed of about 700 kilometers per hour. Around the Sun, he will withstand a temperature of up to 2,5 thousand degrees Fahrenheit (1377 degrees Celsius). For this purpose it is coated carbonaceous shield thickness of 11.4 cm.
