NO SPACE CRAFT HAS EVER

LANDED ON THE SUN.

IT'S JUST TOO HOT!

BUT THE PARKER SOLAR PROBE WILL

GET PRETTY CLOSE, REACHING THE

SUN'S OUTER EDGE, THE CORONA.

THAT'S WITHIN ABOUT THREE POINT

EIGHT MILLION MILES FROM THE

SUN'S SURFACE.

WHILE THE CORONA CAN BE AS HOT

AS A MILLION DEGREES FAHRENHEIT,

SOME PARTS ARE COOLER.

SO, THE PROBE WILL ONLY HAVE TO

SURVIVE TEMPERATURES OF ABOUT 25

HUNDRED DEGREES FAHRENHEIT.

STILL, THAT'S FOUR TIMES AS HOT

AS THE MELTING POINT OF LEAD.

AT ITS CLOSEST APPROACH, THE

PROBE WILL TRAVEL 430,000 MILES

PER HOUR AROUND THE SUN.

IF YOU COULD TRAVEL THAT FAST ON

EARTH, YOU COULD GO FROM

PHILADELPHIA TO WASHINGTON DC IN

ONE SECOND.
