US space agency NASA is on-schedule to launch a car-sized spacecraft in August to Sun, in an attempt to study the star closer than any human-made object ever has.
The probe will face heat and radiation like no spacecraft has endured before, revealing mysteries behind the lifeline of our solar system.
The Parker Solar Probe, a robotic spacecraft -- the size of a small car -- is slated to launch from Cape Canaveral in Florida on a United Launch Alliance Delta IV Heavy, with August 6 targeted as the launch date for the planned seven-year mission.
It is set to fly into Sun's corona within 3.8 million miles (6.1 million km) from the solar surface -- seven times closer than any other spacecraft.
The probe, named after American solar astrophysicist Eugene Newman Parker, will have to survive difficult heat and radiation conditions. It carries a line-up of instruments to study the sun both remotely and directly.
Parker Solar Probe has been outfitted with a heat-shield designed to keep its instruments at a tolerable 29 degrees Celsius even as the spacecraft faces temperatures near 1,370 degrees Celsius at its closest pass.
