>> Stephen: HEY, EVERYBODY, WELCOME BACK TO "A LATE SHOW."

MY GUEST TONIGHT IS THE DIRECTOR OF THE HAYDEN PLANETARIUM AT THE

AMERICAN MUSEUM OF NATURAL HISTORY, THE HOST OF "STAR TALK"

AND "COSMOS," AND THE AUTHOR OF THE NEW BOOK, "COSMIC QUERIES."

PLEASE WELCOME BACK TO "A LATE SHOW," NEIL deGRASSE TYSON!

>> Stephen: NOW, BECAUSE YOU'RE AN EDUCATOR, YOU ARE

ELIGIBLE TO GET THE COVID VACCINE HERE IN NEW YORK.

AND I UNDERSTAND THIS MORNING YOU GOT THE SECOND SHOT.

NOW, I'VE HEARD-- >> I GOT THE SECOND SHOT 11

>> Stephen: OKAY, AND I HEARD THAT THEY CAN-- IT CAN FEEL A

I WAS NEVER MUCH OF A SIDE EFFECTS GUY MY WHOLE LIFE, SO I

DON'T EXPECT TO-- TO PUT A CHECK IN ALL THE BOXES THAT THEY LIST.

BUT, OTHERWISE, YEAH, IF I'M OTHERWISE INCOHERENT, THAT COULD

>> Stephen: HERE YOU ARE GETTING THE FIRST DOSE 28 DAYS

AND I DIDN'T KNOW THAT ONE POSSIBLE SIDE EFFECT OF THE SHOT

(  LAUGHTER  ) SUN'S NOT EVEN OUT, BUT GUNS ARE

>> THAT'S JUST WHAT'S LEFT OVER FROM 40 YEARS AND 40 POUNDS AGO

>> Stephen: I WOULDN'T-- I WOULDN'T FACE YOU IN THE

WHAT IS-- WHAT IS THE SIGNIFICANCE OF YOU GETTING THE

FIRST OF ALL, CONSIDER WHO WE THINK OF NORMALLY AS HEROES IN

OFTEN IT'S SOMEONE WHO SAVES A LIFE OR SEVERAL LIVES.

AND PUTTING THEIR OWN LIFE AT RISK, SOMETIMES.

AND WHEN I THINK OF THE COVID VACCINE DEVELOPED BY LAB

RESEARCHERS, WHAT THAT TELLS ME IS THAT THERE'S A GROUP OF

SCIENTISTS WHOSE NAMES YOU WILL NEVER KNOW.

YET, THEY WILL HAVE SAVED MILLIONS OF LIVES BY DEVELOPING

AND SO, SO I THINK THAT IS THE APPROPRIATE USE OF THE TERM

SO SCIENTISTS MAY BE THE ONLY AUTHENTIC, LEGITIMATE SUPER

HEROES IN SOCIETY, AND I TIP MY HAT TO THEM, EVEN THOUGH WE

CANNOT RECITE THEIR NAMES BECAUSE WE DON'T KNOW THEM, AND

>> Stephen:  OKAY, LET'S GET TO SOME OTHER HARD SCIENCE HERE.

THERE ARE A WHOLE LOT OF MARS MISSIONS GOING ON RIGHT NOW.

WHO DO WE GOT UP THERE RIGHT NOW, BESIDES NASA ARE

AND THE UNITED ARAB EMIRATES, THE FIRST TIME AN ARAB STATE HAS

>> Stephen: ARE THEY-- ARE THEY IN ORBIT AROUND MARS OR HAS

>> SO CHINA HAS AN ORBITER, A LANDER, AND A ROVER.

THE UNITED ARAB EMIRATES HAS AN ORBITER THAT'S SPECIFICALLY

TUNED TO LOOK AT AND SAMPLE THE ATMOSPHERE.

BECAUSE SOMETHING BAD HAPPENED-- I DON'T WANT TO VALUE JUDGE IT.

SOMETHING HAPPENED ON MARS WHERE MARS USED TO HAVE LIQUID RUNNING

WATER ON ITS SURFACE, AND NOW IT'S BONE DRY.

SO THEY'RE GOING TO STUDY THE OUTER ATMOSPHERE OF MARS JUST TO

SEE IF THERE ARE CLUES THERE AS TO WHAT MIGHT HAVE HAPPENED TO

WE SENT A ROVER, PERSEVERANCE ROVER, WHICH MY FAVORITE PART OF

IT'S GOT A HELICOPTER AND ENGINEERS THOUGHT THIS THROUGH

BECAUSE THE MARTIAN ATMOSPHERE IS MUCH THINNER THAN ON EARTH.

IF YOU'RE GOING TO LIFT A PAYLOAD YOU NEED WIDER ROTOR

BLADES, AND YOU HAVE TO SPIN THEM FASTER.

BUT GRAVITY ON MARS IS LESS, SO THAT HELPS YOU OUT.

IT'S MOSTLY AN ENGINEERING DEMONSTRATION, BECAUSE IF THAT

WORKS, YOU'RE NO LONGER LIMITED TO LOW SLOW-MOVING ROVERS.

>> Stephen: HOW DOES IT GET BACK TO THE ROVER ITSELF?

LIKE, WHAT'S-- HOW DOES IT ORIENT ITSELF?

>> THERE ARE WAYS TO COMMUNICATE WITH YOU'RE NOT ON EARTH, AND
