>>WE CAN NOW SAY THAT HUMANS
HAVE FLOWN A ROTER CRAFT ON
>>ANOTHER PLANET.
[APPLAUSE]
>> HELLO, EVERYONE.
WELCOME TO ANOTHER NASA SCIENCE
LIVE.
I AM THE NEWS EVENT AND PROJECT
SUPERVISOR.
WILL BE YOUR HOST FOR TODAY'S
EPISODE.
TODAY WE WILL TALK ABOUT THE
HISTORIC SITE OF INGENUITY
HELICOPTER AND WHAT IT COULD
MEAN FOR THE FLIGHT IN THE
FUTURE.
OVER THE PAST MONTH WHAT THEY
CAN MEAN FOR EXTRA TERRESTRIAL
FLIGHT IN THE FUTURE.
OVER THE PAST MONTH, NASA HAS
BEEN PUSHING THE BOUNDARIES OF
WHAT IS POSSIBLE AND TURNING
SCIENCE INTO SCIENCE FACTS.
ON APRIL19th.
THE INGENUITY MARS HELICOPTER
BECAME THE FIRST SPACECRAFT TO
ACHIEVE POWERED CONTROL FLIGHT
ON ANOTHER WORLD.
SINCE THEN, IT HAS COMPLETED
FOUR FLIGHTS THAT HAVE TAKEN THE
FOUR-POUND SPACECRAFT HIGHER,
FURTHER, FASTER, THAN EVER
BEFORE.
AND NOW THAT THE HELICOPTER IS
PAST PASSED THE TECHNOLOGY TEST,
IT GETS TO TRY NEW THINGS
INGENUITY HAS STARTED THE
OPERATIONAL DEMONSTRATION WHERE
IT WILL TRY FLY ALONG WITH THE
FELLOW ROW POT, NASA'S
PERSEVERANCE ROVER AND IT WILL
TEST HOW IT WILL WORK.
INGENUITY RECENTLY DEMONSTRATED
IT COULD FLY LONG DISTANCES
ABOUT ONE AND A THIRD FOOTBALL
FIELDS OUT THEN BACK AGAIN.
TAKING LOTS OF PICTURE ALONG THE
WAY.
THE FOURTH FLIGHT WAS THE MOST
AMBITIOUS SO FAR.
LET'S TAKE A LOOK.
>> ALL RIGHT.
I SEE DATA PRODUCTS COMING IN,
SO I THINK WE ARE READY TO
PROCESS.
TELEMETRY SHOULD BE IN.
>> I HAVE A CLOSE TO SHOW.
I AM SHOWING HELICOPTER FLYING
OUT AND BACK.
GOING OUT AND BACK.
[APPLAUSE]
>> THAT IS A ROOM FULL OF HAPPY
ENGINEER ALSO IN.
THE TEAM IS WORK ON PLANNING THE
FIFTH FLIGHT SO WE HOPE THEY GET
TO LOOK THE SAME WAY AGAIN SOON.
SO ALSO SEA NOW TALK TO THE
EXPERTS.
SO BECAUSE THIS HISTORIC FLIGHT
ON MARS HAS IMPLICATION FOR HOW
WE WILL EXPLORE OTHER WORLDS,
WE'RE AROUND TODAY BY THE MARS
HELICOPTER BY THERE AND A TEAM
MEMBER FROM NASA'S UPCOMING
DRAGONFLY MISSION.
WHICH WILL TAKE FLIGHT TO WHOLE
OTHER WORLD SATURDAY'S MOON.
YOU CAN JOHN THE CONVERSATION,
TOO, SUBMIT YOUR QUESTIONS ABOUT
INGENUITY AND DRAGONFLY USING
THE HASHTAG ASK NASA AND WE'LL
ANSWER AS MANY AS WE CAN THOUGHT
THE SHOW.
SO RIGHT NOW.
WELL A NOD TO ASIAN AMERICAN AND
PACIFIC EYE LEARN HERITAGE MONTH
IN MAY, I AM JOINED BY JOHNNY
LAMB, A PILOT FOR THANK YOU SO
BOTH SO MUCH FOR JOINING US?
THANK YOU FOR HAVING US.
>> SO JOHNNY, NAS SASS CAN BE
TECHNICAL.
CAN YOU EXPLAIN WHAT THE TITLES
MEAN?
WHAT DO YOU ACTUALLY DO ON YOUR
MISSIONS?
SO JOHNNY, WE WILL START TO YOU.
>> ACTUALLY GUIDANCE OF
ENGINEER.
WHICH IS ALSO A LITTLE BIT
TECHNICAL, TOO.
SO ON INGENUITY, I WORKED ON THE
TEAM THAT DEVELOPED THE FLIGHT
CONTROL ALGORITHMS AND THE
FLIGHT CONTROL SOFTWARE, AND NOW
THAT INGENUITY IS PART OF AN
OPERATIONS PHASE, I AM ONE OF
THE PILOTS WHICH INVOLVES DOING
A LOT OF THE FLIGHT PLANNING
THAT GETS LOADED TON THE
HELICOPTER THEN DOWNLOADED THE
DATA OFF THE HELICOPTER THEN
ANALYZING THE POST FLIGHT
RESULTS AFTERWARDS.
WHAT ABOUT YOU?
>> THANK YOU.
I WORK AT THE JOHNS HOPKINS
APPLIED PHYSICS LAB IN MARYLAND
WHERE I AM ON A TEAM WORK ON
MOBILITY.
MOBILITY IS A SYSTEM THAT WILL
TELL DRAGON FLY HOW TO FLY PLACE
TO PLACE ON TITAN.
MY MAIN JOB ON DIE DAY BASIS TO
HELP COORDINATE ACTIVITIES
ACROSS CERTAIN ASPECTS OF
MOBILITY.
FOR EXAMPLE, ONE OF THE THINGS
DOW IS WORK ON THE CAMERAS AND
ALGORITHMS THAT WILL TELL
DRAGONFLY WHILE IT IS GOING
WHERE IT IS FLYING ON TITAN.
WILL ADD, WHITETAILS CAN HARD TO
UNDERSTAND, VERY CRYPTIC
SOMETIMES.
SO FOLKS WILL USE THE TEAM
DRAGONFLY YEARS.
>> NICE.
WE GOT A DRAGONFLY YEAR AND A
MARS HELICOPTER PILOT WITH US
TODAY.
ALL RIGHT.
SO PERSEVERANCE CARRIED A LOT OF
TECHNOLOGY IT TWO THE RED FLAN
THE.
ONE OF THE EXPERIMENTS IS THE
INSTRUMENT THAT SHOWS US THE
OTHER WEEK THAT OXYGEN CAN BE
EXTRACTED FROM THE MARTIAN ASTRO
NOTE IT
THE INSTRUMENT HELPED PREP FOR
HUMAN EXPLORATION BY PROVIDING
INFORMATION ABOUT WEATHER,
CLIMATE BE?
SURFACE RAD AS AND DUST.
SO WHAT KINDS OF HORIZONS DOES
THE MARS HELICOPTER TECHNOLOGY
DEMONSTRATION OPEN UP FOR FUTURE
NASA MISSIONS?
>> SO I THINK, THE SUCCESS OF
INGENUITY, WE BASICALLY DINE OF
UNLOCK THE AREA OF DIMENSION TO
EX FOR PLACING.
SO WE ALWAYS KIND OF HAD OR
BITTERS WHO CAN PROVIDE
OBSERVATIONS FROM HI HUP HIGH
ABOVE.
WE HAD ROVERS WHO CAN PROVIDE
OBSERVATIONS FROM WAY CLOSE TO
GROUND AND THEN, NOW, THIS
PROVIDES US ANOTHER DIMENSION
AND TO KIND OF EXPLORE THIS GAP
IN BETWEEN WHERE WE CAN KIND OF
REACH HARD TO REACH AREAS.
WE CAN PROVIDE IMAGES.
RECONNAISSANCE, WE CAN SCOUT
AHEAD.
WE CAN LOOK FOR THE BEST AND
EVENTUALLY ALL OF THESE THINGS
CAN ALSO HELP WITH HUMAN
EXPLORATION ON MARS OR OTHER
PLANETS.
>> YEAH.
YEAH.
KNOW YOU GUYS HAVE DONE A LOT OF
TESTING ON EARTH, NO HE, THERE
IS A SPACE SIMULATION JPL.
HAVE YOU LEARNED FROM FLYING
THIS HELICOPTER ON MARS WE COULD
NOT GAIN FROM FLYING TO THE
CHAMBER ON EARTH?
>> SO, THAT IS A GOOD QUESTION.
SO WE, WE SPEND A LOT OF TIME IN
THE 25-FOOT SPACE SIMULATOR ON
JPL.
IT IS A BIG CHAMBER.
WEAR SMALL HELICOPTER.
EVEN WITH ALL OF THAT.
WE WERE ONLY ABLE TO GO ABOUT A
METER UP OFF THE GROUND AND
ABOUT HALF METER SIDE TO SIDE.
AND WE ALWAYS HAD APE LOFT
CABLES, WIRES, GROUND SUPPORT
EQUIPMENT, ALL WHILE TRYING TO
SIM SLATE MARTIAN, AN
ENVIRONMENT.
NOW, WE'RE HERE IN MARS.
WE HAVE BEEN KIND OF FREED OF
ALL OF US AND ALLOWED TO.
WHAT WE DEMONSTRATED WE CAN
CONTROL A FLIGHT IN THE ACTUAL
MARTIAN ENVIRONMENT AND AS WE
SHOWED YOU LIKE FLIGHT THREE AND
ABLE TO FLY 50METERS DONE THE
RANGE AND THE FURTHEST WE HAVE
GONE AND IN THE PROCESS WE ARE
VALIDATING ALL.
WE ARE VALIDATING A THE TESTING.
WE ARE ABLE TO INFORM, REMIND
THE MODELS THEN IT TURNED A LOT
OF IT MATCHED REALLY WELL.
AND NOW, WE ARE CLOAK ALL OF
THOSE VALUABLE ENGINEERING DATA
BACK SO WE CAN HELP DATA MINDED
AND CREWS AND OUR KNOWLEDGE FOR
FUTURE MISSIONS NOW AS WE MOVE
ON TO OPERATION OF DEMONSTRATION
PHASE, WE ARE GOING TO LARN HOW
TO WORK PERSEVERANCE.
WE WELL TRY TO FIGURE OUT HOW TO
PLAY TOGETHER SO THAT IT IS MORE
FUTURE MISSIONS ON HOW THEY
WOULD HANDLE THE FEATURE.
>> YES.
GOING TO BE A LITTLE BIT LIKE A
BUDDY MOVIE.
ALL RIGHT.
WHAT MAKES IT HARD AT MARS THE
ATMOSPHERE IS THIN BUT TITAN,
THE DIFFERENT WORLD ENTIRELY,
HAS A MUCH DENSER ATMOSPHERE
THAN MARS AND I KNOW WE TALKED
ABOUT HOW, YOU KNOW, IF YOU WERE
TO KIND OF GET SOME SPEED GOING,
YOU COULD ACTUALLY SOAR FOR QUIT
A BIT OF TAME ON YOUR OWN.
WHAT CAN A DRAGONFLY MISSION
LEARN THE MARS HELICOPTER.
>> THAT IS A GREAT QUESTION.
I WILL SAY WE'RE ALWAYS LEARNING
FROM PAST SPACE MISSIONS HERE AT
APL EVERY TIME WE BUILD A
SPACECRAFT WE APPLY THOSE
LESSONS TO LATER EFFORTS.
IN PARTICULAR, YEAH.
WE WERE EXCITED TO SEIZE
INGENUITY FLY ON MARS.
DIFFERENCES BETWEEN DRAGONFLY.
THERE ARE A LOT OF SIMILAR US
WHEN ARE DESIGNING AND OPERATING
A VEHICLE ON ANOTHER PLANET.
TO FLY, ONE EXAMPLE IS THAT
FLIGHTS FOR INGENUITY AND
DRAGONFLY ARE AUTONOMOUS.
TITAN IS FAR FROM EARTH.
IT TAKES OVER AN HOUR TO SEND
DATA TO TITAN.
OVER AN HOUR TO GET TO THE DATA
BACK.
WE CANNOT HAVE SOMEONE DRIVING
OR FLYING FROM THE EARTH.
WE NEED TO DRAGONFLY TO BE ABLE
TO GO FROM FLIES PLACE ON ITS
OWN LIKE INGENUITY.
SO THE INGENUITY THE TEAM
EXPERIENCE FLYING AUTONOMOUSLY
ON MARS WILL BE VIABLE.
WE WILL LEARN FROM THE
CHALLENGES THEY FACE.
THEN, THEN HOW THEY SOLVE THEM.
WELL, I WILL SAY THAT, ANOTHER
REASON I AM EXCITED ABOUT
INGENUITY AND DRAGON FLY, OF
COURSE, THEY PROVIDE INSPIRATION
SAN PROVIDE AND HELP US PUSH
FURTHER.
AND NEXT GENERATION OF
SCIENTISTS AND STUDENT LIKE MY
OWN DAUGHTERS.
AND PURSUE AND YOU KNOW, MAYBE
THEMSELVES WORK WITH DRAGON FLY
AND GET TO TITAN IN THE 20 30'S
AND CONTINUE FOR OTHER PLACES.
>> YEAH.
IT IS HARD TO FIGURE OUT HOW TO
FLY ON ANOTHER WORLD, SO WHY
WOULD WE EVEN WANT AN AERIAL
DIMENSION TO EXPLORE TITAN?
>> YEAH.
I THINK, JOHNNY PUT IT VERY WELL
EARLIER.
FLYING OPENS UP A LOT OF
POSSIBILITIES RIGHT.
WE CAN COVER A LOT OF GROUND.
THE LARGER AREA THAN WE COULD
OTHERWISE.
WE CAN DO THE SCIENCE
INVESTIGATION A LOT OF DIFFERENT
PLACES ON TITAN ON THE SURFACE
AND COLLECT DATA WHILE IN THE
AIR.
AND IN PARTICULAR.
AND RELATIVELY EASY THANKS TO
LOOK YOU MENTIONED A THICK
ATMOSPHERE THERE AND LOW
GRAVITY.
IN FACT, TITAN ACTUALLY HAS
LOWER GRAVITY THAN EARTH'S MOON.
IF YOU LIKE TO SUBMIT A QUESTION
DURING THE SHOW AND ASK AS? OR
COME MEN IN THE STREAM WHEREVER
WATCHING.
SO OUR FIRST QUESTION IS FROM
ERICA ON TWITTER ASKS: WHAT HAS
SURPRISED YOU THE MOST ABOUT
THREE ACCOMPLISHES SO FAR.
WHY DON'T WE START WITH JOHNNY
AND YOU CAN LET ME KNOW IF YOU
HAD ANYTHING THAT SURPRISED YOU?
>> WELL, WAY SO SAY THAT THE
MOST.
HOW WELL EVERYTHING PERFORMED ON
MARS.
WE HAVE BEEN LOOK A THE FLIGHTS
GETTING BACK THE DATA AND DUG
INTO.
THEY MATCHED EXTREMELY WELL WITH
OUR MODELS AND HOW WE TESTED IT.
AND IT HAS BEEN PLEASANT
SURPRISE.
IT IS WONDERFUL TOLL SEE.
>> DID YOU HAVE ANYTHING THAT
SURPRISED YOU AS YOU WERE
WATCHING THE INGENUITY FLIGHTS.
>> WELL, ONE OF THE THINGS THAT
SURPRISED ME.
WELL, USUALLY SPACEFLIGHT,
RIGHT.
WE TRAY TO USE HARDWARE THAT HAS
BEEN TESTED EXTENSIVELY IN SPACE
AND TAKE THOSE RISK BUT LEARNING
THEY HAD USED COMMON CELL PHONE
PROCESSORS FOR EXAMPLE.
SO IT IS REALLY INSPIRING AND
SURPRISING TO ME AND WON DEVELOP
SEE.
>> GREAT.
NEXT QUESTION COMES FROM MOON TO
MARS QUEST ON TWITTER.
WILL FLIGHT TESTING, THE QUAD
CHOPPER DRAGONFLY BE SIMILAR TO
PERFORMED AT THE HIGH VACUUM
CHAMBER OR SPASM STRONG
FACILITY.
WHERE WILL IT BE TESTED.
THAT IS A GOOD QUESTION.
SO THE DRONE WE HAVE A MOLD
DRONE WE FLY TO TEST OUR
ALGORITHMS AND SENSORS AND SO
FORTH.
AS THE VIDEO CURRENTLY SHOWING.
WOMEN'S YOU A FLY AT VARIOUS
LOCATION.
A LOT HERE AT APL WE PLAN ON
GOING OUT TO THE U.S. TO RUN IN.
THAT IS THOSE IN OF THE STORY.
SO THE ACTUAL DRAGON FLY LANDER
IS QUITE LARGE THE SIZE ACTUALLY
MAKES IT DIFFICULT TO TEST THE
FULL SCALE HERE ON EARTH.
SO SUPPLEMENT THE DRONE TEST
WE'RE BUILDING WITH SIMULATIONS
AND A LOT OF SIMULATIONS TO
COVER ALL THE VARIOUS
POSSIBILITIES OF WHAT WE THINK
MAKES EXPERIENCE WHEN WE GET TO
TITAN.
>> GREAT.
AND SO, TWITTER ASKS, AND I WILL
APPLY.
JOHN YOU CAN TALK ABOUT MARS.
YOU CAN TALK ABOUT TITAN.
>> WHATS THE GREATEST CHALLENGE
TO SUCCESSFUL FLIGHT AND HOW TO
DO COUNTS?
>> THAT IS A GOOD QUESTION.
SO I THINK ALWAYS THE MOST
CHALLENGING PARTS TO THE FLIGHT
ARE GOING TO BE THE TAKEOFF AND
THE LANDING.
AND CERTAINLY WHERE EVERYTHING
KIND OF WORK OR IT DOESN'T.
FOR THE TAKEOFF, WE KIND OF DO,
WE GAT SCHEME WHERE EVENTUALLY,
WE APPLY A LARGE AMOUNT OF
THRUST TO KIND OF HOP IT OFF THE
GROUND AND AT THIS POINT.
WE DO A CONTROLLED FLIGHT UP TO
THE ALTITUDE WE WANT TO.
AND THEN ON LANDING, WE ACTUALLY
DRIVE IT DOWN AT A METER PER
SECOND COMING DOWN THEN WE WAIT
UNTIL WE DETECT ENOUGH OF THE
VELOCITY TO DETERMINE THAT WE
ACTUALLY REACHED THE GROUND AND
THEN, THEN THE FLIGHT.
>> AND WHAT ABOUT TITAN WHAT'S
THE GREATEST CHALLENGE THERE?
>> I CAN SAY A COUPLE OF THINGS
THAT WE ARE LOOKING AT INCLUDE
THE NORMAL ENVIRONMENT.
BY THAT I MEAN TEMPERATURE ON
THE SURFACE OF TITAN IS VERY,
VERY COLD ABOUT NEGATIVE
300DEGREES FAHRENHEIT WHICH IS
HARD TO FATHOM.
RIGHT.
WE DON'T HAVE ANY EXPERIENCE
HERE ON EARTH.
AND DESIGNING A LANDER THAT CAN
SURVIVE THOSE TEMPERATURES AND
OPERATE ON THOSE TEMPERATURES IS
A CHALLENGE AND NOT ALONG, KNOW,
WHAT HE SAYS IS ALSO TRUE,
RIGHT?
YOU KNOW, BUILDING SOMETHING
THAT CAN TAKE OFF FROM A
LOCATION FLIGHT TO ANOTHER
AUTONOMOUSLY IS DIFFICULT AND
ONE OF THE MANY CHALLENGES WE
FACE.
>> FANNED I MAY.
AND HE IS RIGHT.
SURVIVABILITY IS A BUGGER
CHALLENGES AS WELL.
THERE IS A LOT OF WORK TO DO TO
SURVIVE IN MARS AND AL THE WORK
THAT WAS INVOLVED TO HAVING THE
HEATER THERE TO KEEP IT AT
CERTAIN TEMPERATURE THEN KEEP IT
THERE LIVE, HAVING IT WAKE UP
EVERY DAY, THERE IS A LOT OF
WORK THAT WENT INTO THAT AND I
LOFT TESTING.
>> YEAH.
I REMEMBER LATER ON THE PROJECT
MANAGER SAY SHE WOULD BE HAPPY
WHEN THE HELICOPTER SURVIVED THE
FIRST SITE.
>> THERE WAS A LOT OF EXCITEMENT
FOR THAT.
>> YEAH.
>> GREAT.
OK.
SO BECAUSE EVERYONE ALWAYS WANTS
TO KNOW ABOUT PICTURES.
ADRIAN ON FACEBOOK ASKS , CAN
DRAGON FLY RECORD VIDEOS AND
SEND BACK TO EARTH AS WELL?
>> THAT IS LENT QUESTION.
WE HAVE A SET OF CAMERAS ONBOARD
DRAGON FLY.
A SCIENCE SET OF CAMERAS CALLED
DRAGON CAM.
A SET OF CAMERAS WE USE FOR
NAVIGATION.
SOMETHING WE CALL NAV TO FLY
FROM ONE LOCATION TO ANOTHER.
WELL BE A TALKING PICTURES
CERTAINLY AND TAKING PICTURES
FREQUENTLY AS WE FLY.
HOWEVER, I WOULDN'T NECESSARILY
CALL IT A VIDEO, AND NOT GOING
TO BE ABLE TO COLLECT HIGHER
RATE LIKE 30 FRAMES A SECOND.
60 FRAMES A SECOND.
THE VIDEOS THAT GET THAT DATA
DOWN EARTH.
THE COUPLE OF CHALLENGES THERE.
THEN, ONE IS YOU KNOW, JUST
DESIGNING A SYSTEM THAT CAN
HANDLE THAT VIDEO DATA OF
EVERYTHING ELSE THAT IS GOING ON
AND ONBOARD THE LANDER.
AND SO FOR EX PEAL.
THE NAVIGATION CAMERAS I CAN
SPEAK AND COLLECT DATA AS WE ARE
FLYING IN ONE PICTURE EVERY
SECOND WHICH IS NOT VERY OFTEN.
THE NEXT CHALLENGES HOW DO YOU
GET THAT DATA BACK FROM TITAN TO
THE EARTH?
YOU KNOW?
IT SOUNDS EASY.
RIGHT?
YOU HAVE A BIG ANTENNA UP ON
DRAGONFLY AND YOU START ENDING
DATA AND UNDERSTAND WHAT DATA
RATES LOOK LIKE.
WE'RE TALKING ABOUT 10ISH FOR A
SECOND BACK TO EARTH.
AND YOU KNOW, WE'LL BE SPENDING
A LOT OF TIME OPTIMIZING WHAT
DATA WE WANT TO BRING DOWN,
WORKING WITH THE SCIENTISTS TO
IF FIGURE OUT WHATS THE MOST
INTERESTING WHEN WE GET TO TITAN
TO IMPLEMENT THAT AND GET WHAT
THE BEST DATA WE CAN DOWN.
>> YEAH.
AND JOHNNY, THERE IS SOME
CAMERAS ONBOARD INGENUITY AS
WELL, RIGHT?
>> YO.
WE HAVE TWO CAMERAS.
WINCE OUR NAVIGATION CAMERA,
THAT IS KIND OF OUR BLACK AND
WHITE CAMERA POINTING MOSTLY
DOWN, SLIGHTLY FORWARD END.
THAT IS WHERE KIND OF THE ICONIC
FIRST FLIGHT IMAGE COMES FROM.
WHERE WE TOOK A PICTURE OF THE
OWN SHADOW.
THEN, WE HAVE THE COLOR CAMERA,
WE CALL IT.
THAT'S THE ONE THAT IS TAKING
IMAGES A LITTLE BIT MORE.
AND NOW WE DON'T HAVE VIDEO
CAPABILITY THERE.
WE WERE FOR THE COLOR CAMERA.
WE TAKE, WE TAKE SOME IMAGES AND
THEN FOR THE NAVIGATION CRAM WE
COLLECT MORE AND HAVE LIMITED
DATA RECORDING, IF YOU WILL.
THAT IS AS LONG AS WE CAN GET
THOSE IMAGES DOWN, AND PROCESS
THEM IN THAT WAY.
BUT WE ARE KIND OF RESTRICTED BY
PROS PING A LITTLE LOAD TRYING
TO COLLECT THAT MUCH DATA IS A
LOT WHILE IN THE MILD OF TRYING
TO MAINTAIN FLIGHT AT THE SAME
TIME.
>> RIGHT.
THERE HAS BEEN SOME THAT CAME
BACK BUT TAKE BY THE BUDDY THE
ROVE, HE RIGHT.
>> AND I KNOW THAT WE HAVE SOME
GREAT ORBITERS AROUND MARS THAT
HAVE BEEN ABLE TO GIVE US THE
HIGH DATA RATES WE'LL HAVE TO
SEE WHAT KIND OF SUPPORT, I
GUESS, YOU GUYS HAVE AT TITAN,
KNOW?
YOU DON'T HAVE A RELAY NETWORK
YET, THERE.
>> THE PLAN FOR DRAGONFLIES
DIRECT TO EARTH COMMUNICATIONS
WHAT WE CALL DTE.
YEAH.
DRAGONFLY HAZE HAS A LARGE
ANTENNA.
THE HIGH GAME ANTENNA OR HGA
WHICH WILL BE DIRECTLY BACK TO
EARTH.
WE DON'T HAVE ANY OTHER SUPPORT.
>> OK.
WELL, THERE IS ANOTHER QUESTION
ABOUT DRAGON FLY.
I DON'T KNOW IF YOU, YOU KNOW,
SETTLED ALL THE THINGS, BUT
ROBERT ON YOUTUBE ASKS WHAT ARE
DIMENSIONS BEING PROPOSED FOR
THE DRAGON FLY MISSION?
>> YEAH.
STILL IN THE MIDDLE OF A DESIGN
PHASE AND THINGS THAT WILL
CHANGE.
IF YOU, YOU KNOW, FAIRLY CLOSE
TO THE SIZE OF A SMALL MONEY
TYPE OF CAR, OR, KNOW, EVEN
CURIOSITY, I AM NOT, I DON'T
HAVE THE EXACT DIMENSIONS OF THE
TIP OF THE TONGUE HERE.
YOU CAN THINK OF IT AS SMALL
CAR.
>> COOL.
OK.
YEAH.
WHICH IS MUCH LARGER THAN
INGENUITY LOOK THE FUSELAGE IS
THE SIZE OF A TISSUE BOX, RIGHT,
JOHN? I YES.
THAT IS ABOUT THE CORRECT
COMPARISON.
>> WAY.
WELL HERE IS A QUESTION ABOUT
THE HELICOPTER.
DOUGLAS ON TWITTER ASKS, WHAT IS
THE FLIGHT CEILING ON MARS?
HOW DOES THAT COMPARE TO EARTH
FOR HELICOPTER OF SIMILAR SIZE?
>> THE FLIGHT CEILING.
I GUESS I AM NOT COMPLETELY
UNDERSTANDING THAT QUESTION
PERHAPS.
>> HOW HIGH COULD IT GO SINCE
THE ATMOSPHERE GETS A LITTLE BIT
RIGHT?
>> I MEAN, I THINK OUR
LIMITATION RIGHT NOW IS OUR
SENSOR PACKAGE.
WE HAVE BEEN COMFORTABLE FLYING
AT FIVE METERS ALTITUDE AND WE
WERE ALSO PLANNING AND
COMFORTABLE GO GOING AS HI AS
15METERS ALTITUDE BUT BEYOND
THAT.
WE START TO GET A LITTLE
CAUTIOUS.
THAT IS OUR LIMIT AT THE MOMENT.
BUT ALL THE FLIGHTS UP TO THIS
DAY HAVE BEEN AT THE FIVE METER
ALTITUDE.
>> YEAH.
OK.
SO TALKING ABOUT SENSORS.
HERE IS A QUESTION ABOUT ENERGY
SO ON TWITTER ASKS, WHAT KIND OF
ENERGY BE USED NEXT GENERATION
OF HELICOPTERS FOR LONG FLIGHTS.
YEAH.
THERE IS LIKE.
LET'S SAY A HELICOPTER THAT GOES
WHY DONE YOU TALK ABOUT THE
POWER SOURCE FOR YOUR CRAFT,.
WHY DON'T YOU GO FIRST.
IT IS THAT STRIP YOU SEE AT THE
TOP.
IT HAS BEEN PERFORMING WELL FOR
US BIFFING US PLENTY OF CHARGE
OVER THE COURSE OF THE DAY AND
THAT WE ARE READY AND POW ONE
WE'RE HEALTHY EACH DAY WE'RE ON
MARS.
YOU ARE MUCH FURTHER AWAY OR YOU
WILL.
HOW DO YOU GET POWER?
>> YEAH.
WE CANNOT USE SOLAR PANELS
UNFORTUNATELY AT TITAN.
BUT WE USE A POWER SOURCE VERY
MUCH LIKE CURIOSITY DO AND IT IS
WHAT CALLED MMRT.
IT IS A BIT OF A MOUTHFUL AND
RADIO ISOTOPE AND ELECTRIC
IT USES A NEW MATERIAL TO
GENERATE HEAT GETS TURNED INTO
ELECTRICITY ONBOARD.
SO PROVIDES ABOUT 50 TO 60-WATTS
OF POWER AND CHARGE BATTERIES
ONBOARD WHICH WILL THEN BE USED
FOR FLIGHT.
OTHER ACTIVES.
OK.
GREAT.
YEAH.
POWER SOURCE THAT HAS BEEN USED
ON MANY MISSIONS BEFORE, TOO.
OK.
WELL, THAT IS ALL THE TIME WE
HAVE FOR TODAY.
SO THANK YOU FOR JOINING US,
JOHNNY.
THANK YOU FOR HAVING US.
THANKS.
GO.
>> GO DRAGON FLY.
>> OK.
