Nasa announces historic mission to send probe to 'touch the Sun'

Nasa announces historic mission to send probe to 'touch the Sun' Nasa announces historic mission to send probe to 'touch the Sun'

The US space agency has revealed the probe will "touch the Sun" as it flies within 3.9 million miles of the star's surface into the solar atmosphere, which is known as the corona.

Boldly planning to go where no human - or spacecraft - has gone before, NASA is to send a probe 93m miles to the Sun.

The Parker Solar Probe, seen here in an artist's impression, will make repeated passes through the sun's corona, or atmosphere, in the mid 2020s to learn more about what generates its extreme temperatures, the solar wind and the titanic storms that can blast Earth with high-energy radiation.

Data obtained in the pursuit of answering those questions will help back on Earth, too, by improving our ability to forecast space weather (triggered by the sun's activity), which impacts satellite functionality and affects astronauts.

The heat: The probe will rely on a 4.5-inch-thick carbon-composite solar shield to help it withstand temperatures up to 2,550 degrees Fahrenheit, reports Orlando's WKMG. Tucker pointed out that the Kepler Space Telescope is steered by solar winds. "We have not been able to answer these questions".

The mission, Solar Probe Plus, will launch in the summer of 2018 and marks the agency's first to the star at the center of the solar system.

"Typically, NASA names missions after scientists that have also contributed to various sciences like astrophysics and so forth, typically after they have passed, so it's posthumously done".

The student's thrashing came at roundabout the same time when the Madurai Bench of the Madras High Court suspended the center's ban for four weeks.

The mission's namesake first theorized the existence of solar wind in a 1958 that posited that high-speed matter and magnetism was escaping the sun.

Normally, NASA waits to rename its missions after launch, but the space agency made a decision to break protocol this time since Parker's work has been so instrumental for the spacecraft's mission.

The sun and its atmosphere consist of several zones or layers.

The plan for the Solar Probe Plus if it goes according to plan.

As the probe passes around the sun, it's expected to reach a velocity of up to 200 kilometres per seconds, making it the fastest man-made object ever created.

These instruments will be used during its trajectory, which will see it use seven Venus flybys over almost seven years to gradually shrink its orbit around the run, coming as close as 3.7 million miles to the sun. But it was confirmed a few years later by observations from NASA's Mariner 2 spacecraft. "It's a spacecraft loaded with technological breakthroughs that will solve numerous largest mysteries about our star", says Nicola Fox of the Johns Hopkins University Applied Physics Laboratory.
