The Sun’s surface has a temperature of around 5,500º C. The solar corona is actually much hotter – around a million degrees – for unknown reasons. This is known as the coronal heating problem, and is one of the Parker probe’s study goals. So how come the probe hasn’t melted yet?
An innovative Heat Shield, advanced Sensors, and an efficient Cooling System helped the Parker Solar Probe stay cool as it approached one of the most hostile environments of the solar system. On April 28, 2021, NASA’s Parker Solar Probe became the first-ever spacecraft to ‘touch’ the sun by plummeting into the depths of the solar atmosphere.
Illustration of Parker Solar Probe circling the Sun. This summer, NASA’s Parker Solar Probe will launch to travel closer to the Sun, deeper into the solar atmosphere, than any mission before it. If Earth was at one end of a yard-stick and the Sun on the other, Parker Solar Probe will make it to within four inches of the solar surface.
But not all of the Solar Parker Probe instruments will be behind the TPS. Poking out over the heat shield, the Solar Probe Cup is one of two instruments on Parker Solar Probe that will not be protected by the heat shield.
So, when we say that the probe has touched the sun, what we mean is that it has flown into the corona. The corona has always been a mystery to scientists because it is almost 300 times hotter than the surface of the sun, despite being much less dense.
That means to study the corona, the Parker Solar probe braves temperatures of around 2,500 degrees Fahrenheit (about 1,400 degrees Celsius) to get up close and personal with the sun. Breaking space news, the latest updates on rocket launches, skywatching events and more!
