Parker Solar Probe to make second launch attempt Sunday

Parker Solar Probe to make second launch attempt Sunday

As the first rays of dawn reached Cape Canaveral on Saturday, the rocket that Nasa hopes will reveal the sun's secrets remained very much earthbound. About this сообщаетAFP, reports the Chronicle.info with reference to the UNN.

In just a few hours, United Launch Alliance will try a second time to launch NASA's highly anticipated Parker Solar Probe.

The Wide-Field Imager for Parker Solar Probe, or WISPR, will photograph the large scale structure of the corona before the spacecraft flies into it, studying coronal mass ejections, jets and other phenomena.

He said: "Wow, here we go!" It hurls powerful plasma and energetic particles that can unleash geomagnetic space storms and disrupt Earth's power grid.

But these solar outbursts are poorly understood.

Recall, probe Parker should be close to a record close of 6.1 million kilometers to the Sun and the first of the previously created mankind apparatuses to enter into so-called solar corona.

Great knowledge about the solar wind and space storms will also help protect future space explorers when they go to the moon or Mars.

Parker, now 91 and eager to watch the craft blast into space, said some people doubted his initial theory.

The Venus flybys will help shape Parker's trajectory, eventually putting the spacecraft into an elliptical orbit with a low point of just 3.8 million miles from the sun's visible surface and a high point around the orbit of Venus.

The spacecraft is protected by a heat shield that will keep it closer to room temperature, about 85 degrees Fahrenheit. The heat shield can withstand radiation equivalent up to about 500 times the Sun's radiation on Earth.

The probe will be controlled from the Mission Operations Centre based at the Johns Hopkins University Applied Physics Laboratory (JHU APL), which is where NASA handles its unmanned missions.

"We are ready. We have the ideal payload". This image made available by NASA shows an artist's rendering of the Parker Solar Probe approaching the Sun. Engineers tried to identifiy the problem, but the launch window - when a spacecraft can take off in the right direction due to the Earth's rotation - closed before they could make progress.

"I'm flattered naturally. That's about all I can say", said Parker.

Scientists have wanted to build a spacecraft like this for more than 60 years, but only in recent years did the heat shield technology advance enough to be capable of protecting sensitive instruments, according to Fox.
