"In addition to using a powerful rocket, the Delta IV Heavy, Parker Solar Probe will perform seven Venus gravity assists over its seven-year mission to shed sideways speed into Venus' well of orbital energy".
The car-sized probe, which will fly closer to the sun than any other man-made object, is set to blast off at 3:33am eastern daylight time (8:33am BST) from Cape Canaveral, Florida on August 11.
NASA's plans for the probe include multiple orbits of the Sun, repeatedly slingshotting itself around the star and gathering vital science data each time it makes its approach.
Nasa's new solar spacecraft is so indestructable that parts of it will be circling the Sun until the Solar System ends, eight billion years from now, scientists have said.
The mission Sun's outer atmosphere, or corona, the closest any man-made instrument has ever got to a star.
If scientists understand more about solar activity, they could use it to predict large solar eruptions that pose a threat to satellites orbiting the Earth.
Nasa says the TPS has been tested to withstand up to 1,650C temperatures and "can handle any heat the sun can send its way".
This is a phenomenon that has baffled NASA scientists because the sun's atmosphere "gets much, much hotter the farther it stretches from the sun's blazing surface".
