COMING BACK FROM NASA'S PERSEVERANCE ROVER.

AND NOW THE ROVER IS BEAMING BACK SOUNDS FROM MARS.

BUT I WANT YOU TO BE CAREFUL.

SOMEONE SENT A FAKE TWEET ABOUT THE MISSION.

SO WE WANT YOU TO BE AWARE.

CHECK THIS OUT.

THIS 26-SECOND VIDEO SHOWING A HUGE SWEEPING VISTA OF THE

MARTIAN SURFACE DID NOT COME FROM PERSEVERANCE, OKAY.

NASA SAYS THAT'S NOT REAL.

BUT STILL, TWITTER USERS HAVE VIEWED IT AT LEAST THREE MILLION

TIMES.

SO IF YOU'VE SEEN IT, NOW YOU KNOW IT'S FAKE.

HERE IS THE REAL RECORDING PERSEVERANCE CAPTURED ON MARS.

♪ ♪ ♪ NOT AS DRAMATIC, BUT STILL COOL.
