"HOUSTON, STATION
ON SPACE TO GROUND."
WELCOME TO SPACE TO
GROUND, I'M NATALIE GOGINS.
THIS WEEK ON STATION, THE
CREW GOT FIRED UP FOR SCIENCE.
EXPEDITION 57 COMMANDER
ALEXANDER GERST PERFORMED SOME
NEEDED MAINTENANCE
ON THE ACME INSERT
IN THE CIR COMBUSTION CHAMBER.
CIR, OR COMBUSTION
INTEGRATED RACK,
ENABLES SAFE COMBUSTION
RESEARCH IN MICROGRAVITY.
ITS "PLUG-AND-PLAY" APPROACH
SUPPORTS A WIDE VARIETY
OF STUDIES ON DROPLET,
SOLID FUEL,
AND GAEOUS FUEL COMBUSTION.
THE ACME, ADVANCED COMBUSTION
VIA MICROGRAVITY EXPERIMENTS
PROJECT, INVESTIGATES 5
DIFFERENT STUDIES WITH THE GOALS
OF IMPROVING FUEL EFFICIENCY,
REDUCING POLLUTION BYPRODUCTS
FROM COMBUSTION, AND
PREVENTING SPACECRAFT FIRES
BY BETTER UNDERSTANDING
MATERIAL FLAMMIBILITY.
AN EXTERNAL EXPERIMENT
ON STATION IS PROVIDING
NEW INSIGHTS TO PULSARS.
THE NEUTRON STAR INTERIOR
COMPOSITION EXPLORER, OR NICER,
PROVIDES HIGH-PRECISION
MEASUREMENTS OF NEUTRON STARS,
ALSO KNOWN AS PULSARS.
PULSARS ARE THE INCREDIBLY
DENSE, CRUSHED CORES
THAT REMAIN AFTER A SUPERNOVA.
BECAUSE PULSARS SHINE MOST
BRIGHTLY IN NARROW BEAMS
THAT SWEEP THE SKY AS THEY
ROTATE, THEY APPEAR TO PULSE
LIKE A LIGHTHOUSE BEACON.
THIS KNOWLEDGE COULD
REVOLUTIONIZE SPACE NAVIGATION
BY USING PULSARS AS BEACONS
TO GUIDE OUR FUTURE
EXPLORATION OF SPACE.
THE FIRST ASTRONAUTS SLATED
TO FLY ON NEW SPACECRAFT
FROM BOEING AND SPACEX
WERE JOINED BY A PAIR
OF FUTURE SPACE STATION
CREW MEMBERS FROM JAPAN
FOR A MARATHON TASTE
TEST IN NASA's FOOD LAB.
ALL CREW MEMBERS BOUND FOR
THE STATION GET A CHANCE
TO SAMPLE THE COSMIC MENU
THAT WILL SUSTAIN THEM WHILE
THEY SPEND TIME IN MICROGRAVITY.
TO SEE THE LATEST NEWS
AS WE MARCH TOWARDS ONCE
AGAIN LAUNCHING ASTRONAUTS
FROM AMERICA, VISIT

OUR TWITTER QUESTION
COMES FROM SHARKBAIT.
THEY WANT TO KNOW:
WHAT IS THE BEST TIME
TO ATTEMPT HAM RADIO CONTACT
WITH CREW ABOARD THE ISS?
HAM RADIO HAS BEEN A PART
OF HUMAN SPACE EXPLORATION
SINCE 1983.
CREWMEMBERS HAVE THE
OPTION OF MAKING CALLS
WITH HAM RADIO AMATEURS
ON THEIR PERSONAL TIME.
YOUR BEST CHANCE IS
LIKELY ON THE WEEKENDS
BETWEEN 06:00 AND 21:30 GMT.
ADDITIONALLY, THE AMATEUR RADIO
ON THE INTERNATIONAL SPACE
STATION PROGRAM, OR ARISS,
CONNECTS STUDENTS IN SCHOOLS
OR PUBLIC FORUMS LIKE MUSEUMS
WITH CREW MEMBERS ONBOARD.
APPLICATIONS ARE OPEN
NOW UNTIL NOV 30TH
FOR 2019 SESSIONS
AT WWW.ARISS.ORG.
KEEP SENDING IN YOUR QUESTIONS
USING THE HASHTAG SPACETOGROUND,
WE'LL SEE YOU NEXT WEEK.
