CUMULUS, STRATUS, AND CIRRUS

RETURN

THESE CLOUDS ARE COMPOSED ENTIRELY OF ICE CRYSTALS

CIRRUS (OR CIRROSTRATUS, OR CIRROCUMULUS)

RETURN

THIS MAN WAS THE FIRST TO USE LIQUID PROPELLANTS AND IS KNOWN AS THE FATHER OF MODERN ROCKETRY

ROBERT GODDARD

RETURN

THIS COUNTRY WAS THE FIRST TO USE ROCKETS AS A WEAPON OF WAR

CHINA

RETURN

THIS INVENTOR WAS THE FIRST TO ADD FLIGHT-STABILIZING GUIDE STICKS TO ROCKETS

WILLIAM CONGREVE

RETURN

THIS IS NOTHING MORE THAN VERY RAPID OXIDATION

COMBUSTION

RETURN

THE SUBSTANCE TO BE OXIDIZED IS KNOWN AS THE

REDUCER

RETURN

THE HEART OF A LIQUID PROPELLANT ROCKET IS CALLED THE

COMBUSTION CHAMBER

RETURN

IF IGNITION IS SPONTANEOUS WHEN THE OXIDIZER AND FUEL COME INTO CONTACT, THE PROPELLANT IS CALLED

HYPERGOLIC

RETURN

THE POINT WHERE AN ORBITING BODY IS CLOSEST TO THE EARTH IS CALLED THE

PERIGEE

RETURN

THIS TERM REFERS TO ANY CLOSED ORBIT THAT IS NOT CIRCULAR

ELLIPTICAL

RETURN

A SPACECRAFT MUST BE ACCELERATED TO AT LEAST THIS SPEED IN ORDER TO ESCAPE THE EARTH’S GRAVITATIONAL INFLUENCE

25,000 MPH

RETURN

THE STUDY OF THE ARC OR TRAJECTORY FOLLOWED BY A NON-ORBITING BODY IS CALLED

BALLISTICS

RETURN

THE SPACE BETWEEN THE EARTH AND THE MOON IS CALLED

CISLUNAR SPACE

RETURN

THE PART OF THE SUN THAT GIVES OFF LIGHT IS A VERY THIN SHELL CALLED THE

PHOTOSPHERE

RETURN

THE SUN’S DIAMETER IS ALMOST THIS MANY MILES

ONE MILLION (ACTUALLY 864,000)

RETURN

THIS ZONE OF ELECTRICALLY CONDUCTIVE LAYERS IN THE UPPER ATMOSPHERE IS WHERE THE AURORA BOREALIS OCCURS

IONOSPHERE

RETURN

THIS CLOUD TYPE IS ASSOCIATED WITH THUNDER AND LIGHTNING

CUMULONIMBUS

RETURN

A LOCAL DOWNDRAFT ASSOCIATED WITH THUNDERSTORMS IS CALLED A

MICROBURST

RETURN

WARMING OF THE EAST PACIFIC OCEAN IS A WEATHER PHENOMENON CALLED

EL NINO

RETURN

WHEN AN AIRCRAFT IS SUBJECTED TO THIS LEVEL OF AIR TURBULENCE, PASSENGERS MUST WEAR SEAT BELTS, AND UNSECURED OBJECTS TEND TO MOVE ABOUT

MODERATE

RETURN

A HURRICANE WITH WINDS OF 160 MPH WOULD BE CLASSIFIED AS THIS NUMBER ON THE SAFFIR-SIMPSON SCALE

5

RETURN

THIS SCALE IS USED TO CLASSIFY THE SEVERITY OF TORNADOES

FUJITA-PEARSON TORNADO INTENSITY SCALE

RETURN

THIS TYPE OF ICE HAS THE APPEARANCE OF FROST AND MAY FORM ON THE SURFACES OF AIRCRAFT FLYING IN STRATUS CLOUDS

RIME ICE

RETURN

PILOTS OF AIRCRAFT APPROACHING TO LAND ON A SNOW-COVERED SURFACE CAN BE SUBJECTED TO THIS CONDITION IF THERE IS ALSO ICE FOG, HAZE, OR BLOWING SNOW

WHITE OUT

RETURN

“TO EVERY ACTION, THERE IS AN EQUAL AND OPPOSITE REACTION” IS NEWTON’S ___ LAW OF MOTION

THIRD

RETURN

THIS ROCKET SYSTEM PROVIDES THE STREAMLINED SHAPE AND CONTAINS THE OTHER SYSTEMS

AIRFRAME

RETURN

THE NUMBER OF POUNDS OF THRUST DELIVERED BY CONCUMING ONE POUND OF PROPELLANT IN ONE SECOND IS REFERRED TO AS

SPECIFIC IMPULSE

RETURN

THIS RUSSIAN SCIENTIST MADE THE FIRST COMPUTATIONS FOR ROCKET FLIGHTS INTO SPACE

KONSTANTIN TSIOLKOVSKY

RETURN

THE SCIENCE AND ENGINEERING OF DEALING WITH STORAGE OF LIQUID OXYGEN AND LIQUID HYDROGEN IS CALLED

CRYOGENICS

RETURN

THESE PARTS OF A ROCKET COMBUSTION CHAMBER ACCELERATE THE HOT GASES TO A HIGH EXIT SPEED

THROAT AND NOZZLE

RETURN

A ROCKET THAT USES BOTH LIQUID AND SOLID PROPELLANTS IN THE SAME ENGINE IS SAID TO USE THIS TYPE OF PROPELLANTS

HYBRID

RETURN

COMMON GUNPOWDER OR A METAL-OXIDIZER MIXTURE SUCH AS MAGNESIUM AND POTASSIUM PERCHLORATE ARE USE TO IGNITE SOLID ROCKETS. THE IGNITERS ARE CALLED

SQUIBS

RETURN

A ROCKET THAT IS SENT STRAIGHT UP TO TAKE MEASUREMENTS IS CALLED A

SOUNDING ROCKET

RETURN

WHEN A COMET IS AT ITS ORBITAL POSITION FARTHEST FROM THE SUN, IT IS SAID TO BE AT

APHELION

RETURN

THIS ELLIPTICAL ORBIT IS TANGENT TO A LOWER AND A HIGHER CIRCULAR ORBIT AND MAY BE USED TO TRANSFER A SPACECRAFT FROM ONE CIRCULAR ORBIT TO THE OTHER

HOHMANN TRANSFER ORBIT

RETURN

IF A SATELLITE’S ORBIT KEEPS IT DIRECTLY ABOVE ONE POINT ON THE EARTH’S SURFACE, THE ORBIT IS CALLED

GEOSTATIONARY

RETURN

CHARGED PARTICLES EMITTED BY THE SUN ARE TRAPPED IN THESE TWO ZONES AROUND THE EARTH
