Recording Accurate Data of Regions
Miles Above the Clouds
THE rose-tinted glow of romance and the cold, steady light of science,
usually as far asunder as the poles, have been united in remarkable
tests that may revolutionize, man's knowledge of the atmosphere.
Prof. Rebert H1. Goddard, originator of the idea of the "moon rocket,"
has fallen in love with a charming young college girl. s
Miss Esther Christine Kisk, of Worcester, Mass., the professor's
fiancee, has become absorbed in the experiments her future husband is
making at Clark University, Worcester, where he is head of the De
partment of Physics.
The moon and levers have been
associated since the earliest ages.
Peets have lhapsedized ever the
spell of romance cast by its silver
flood of light.
But te Dr. Goddard and his bride-te-be
the moon has become the sym
bol of a scientific goal. The super
rocket which he is planning, if suc
cessful, will add one mere victory
te man's conquest of nature.
Dr. Goddard became renowned
overnight several years age when
the world learned of the great rocket
he was planning te sheet into in
finite space.
The public fancy wac caught with
the suggestion that eventually the
Goddard super-rocket might carry
a man te the moon. Numerous men
and some women offered te attempt
the trip. ' ,
But the professor is net interested
primarily in any attempts te reach
the moon. What he wants te de is
te solve the mysteries of the spaces
beyond the earth's atmospheric
He wants te learn the density, the
chemical composition and the tem
perature at various pianos of ele
vation. He hopes that hi3 invention will
enable aviators te chart the sky and
gain reliable information as te flying
conditions at great heights.
He wants te learn mere of "geo "gee "geo

surface of the earth, which is said te
comprise the fourth region of the
In two years Dr. Goddard expects
te reach his scientific goal. Scien
tists in this country, in Europe and
even in Africa are in touch with his
Initial Steps in Leve
and Research in 1917
It is a coincidence that the first
step that brought exceptional prog
ress with the model rocket was made
by Dr. Goddard in 1917, the year he
met Miss Kisk. She graduated from
the Seuth High Scheel in Worcester
in that year and became secretary
te Dr. Edmund P. Sanferd, then
president of Clark University.

Since then the work has net prog
ressed as rapidly owing te a lack of
funds, but ngnin financial nsslstnnc"
hns come from nn unexpected qunrtcr.
The source hns been especially gratify
ing te Dr. Goddard. in that It is in
dicative of the confidence which the
trustees of his university have in his
theories, despite the fact thnt the ex
periment has net ndvnnccd beyond the
model stage.
Dr. Goddard wns in his laboratory at
Worcester when he consented te tell of
his experiments. Before him wns a
model of the rocket ever which he has
worked for seven years.
"I have faith in the possibilities of
the rocket," he said, "net only as an
aid te science in determining the den
sity, chemical composition nnd tempera
ture of the atmosphere, but also us a
means of exploration."
"De you really believe that eventually
you will bu able te send a human being
te the moon?"
Prof. Goddard's smile gave way te n
leek of seriousness.
"I think the suggestion of such an
achievement tame from my original
paper te the Smithsonian Institution,"
he answered.

"there hnvc been repeits from time te

"The possibilities of the rocket which
I have outlined In theory and have
brought te'n degree of perfection in

Dr. Goddard replied.
"I must make it clear, however, that

it becomes essential that I keep silent
until such time ns the institution is pre

It will enable me te mnke meie ex

Many Have Offered
te Take Lunar Trip
Thnt ninny people throughout the
world hnve taken serious cognizance of
Dr. Gedelnrd's experiments is evinced
by the large number of letters he bus
received from persons eager te take n
trip te the moon.
"When my theory wns first made
public." said Dr. Oeddnrd. "I re
ceived letters from men who desired te
ride te the moon. They are still com
ing. .Only recently I get u letter from
a woman in Kansns City. Me., who
appealed for the opportunity te take the
rocket trip.
"The majority of the writers, how
ever, reveal in their letters that they
nre nnlmntcd bv the desire for publicity.
Their offers are net te be taken seii seii
euslv as nn effort te give scientific as

letters from scientists who have offered
their services. Seme of them pro'iese
journeying te Worcester te aid the
professor in the Clnrk laboratory.

dnrd. "He Is a French engineer, but
his experiments nre net being conducted
with the Lien of exploring extreme alti
tudes." The amount of money which Clark
University trustees have placed nt the
disposal of Dr. (Jeddard te further hN
experiments has net been made public.
Dr. (ieddaril contents himself with the
statement that It Is a modest amount,
but entirely adequate for the work In
hand. The trustees nre likewise un
communicative, but they say the up up up
proptintlen was made becnuse they had
tnlth in the practicability of the pieject.
It is net the sensational idea of
sheeting a human being te the moon
that hau attracted the attention el
scientists und impressed the university
tiustees, but rather the possibilities for
scientific inclination which has long
been desired.
Dr. (Jeddard says that while his
theory Is net being worked out with the
idea of getting data en weather condi

be an immeasurable nlil te the weather
Observations May Aid

"The observations that could be
made with rockets and proper Instru

he suld. "I think the time Is net se

be employed te ascertain Hying condi
tions. "This is one of the Immense possi

"This highest sphere appears te con

Nichelson's theory of the atom, and

"The greatest altitude at which

"Slmultnneeus dally observations at
n large number of stations of the vari

wind velocity would doubtless be of
great value in weather forecasting.
The theory, which I have worked out. Is
well suited for such a purpe-e, in that
the time and rise of such a fall would
be short, se that the apparatus would
readily be found en Us return. The
expanse would be slight, being simply
that of a fresh magazine of cartridges

Could Recover Rocket
by Means of Parachute
The recovery of appnrtus en Its re
turn, Dr. Goddard says, need net be
n difficult mntter, inasmuch ns the time
of accent even te great altitudes In
the atmosphere will be comparatively
short, due te the high speed of the
rocket throughout Its entire course.
The time of descent will nlse be short,
but a free full can be prevented satis
factorily by n suitable parachute. A
parachute will be operative, lie says,
for the reason thnt high veloc
ities nnd small atmospheric densi
ties nre essentially the same ns low
velocities nnd erdlnnry density.
l'ven If a mnss of one pound were
propelled by the nppnrntus until it
possessed sufficient momentum te escnpe
the earth's attraction, the propelling
mass need net be unreasonably large,
for n high velocity of ejection would
be attainable.
Dr. Oeddard has net been unmind
ful of the popular discussions thnt have
ensued concerning the merits of his
theory and the possibilities It presents.
He hns given careful consideration te
nil questions that have been raised and
has net failed te convince his critics
of the faith lie hns in the principle
and the ultlmnte success of his project.
Dr. Oeddnrd says that te nianv
people the operation of n jet In a
vacuum is still n mystery. However,
he says the phenomenon is easily un
derstood if one thinks of the ejected
gns as a t barge of fine shot, moving
with a very high velocity. The cham
ber will react or kick when the charge
is fired, exactly u' a shotgun kicks
when firing a charge of erdlnnry shot.
An objection which Dr. Oeddard has
answered is that if a rocket were te be
inniected te an infinite distance, the
nppnrntus would engender great frie-
tmn while passing through the nlr, nnd
If it moved with a speed as grcnt as one
and one-half miles per second outside
the atmosphere, It would catch fire by
fiictinn or fly te pieces, because of the
I excessive speed.
He declares that the Initial speed
does net exceed two thousand feet per
second ever the first twenty-live miles,
' beyond which the density of the ntmes-
pheie Is negligible. He snys the Idea
of 11 bedv Hying te pieces is unfounded,

Illustrative of Tils knowledge of the

human Interest element in his rocket
experiment is the following incident he
told students of the Worcester Poly
technic Institute, for which Institution
he has a deep affection born of his stu
dent days, and because many of his
most Important experiments were per
formed there :
"It Is probable that the points which
the average person would desire most,
te have discussed are sheeting the moon
and allied problems.
"After the announcement of my
theory by the Smithsonian Institution
the popular Impression was se much in
evidence that a moon-sheeting device .
wns under way, and that all the public
needed te de wns te sit still and watch
it, that I believed it necessary te cor
rect the Impression. But I wanted at
(the same time te hint thnt further ex
periments would lead te even mere In
teresting results.
"My statement wns token mere con
servatively thnn I had anticipnted, but
in the light of subsequent events I was
very glad thnt this was se. In the first
place, I am net a sensationalist, even
though I realize I am dealing with a
scnsatiennl subject. I almost wish I
were, for I could certainly start some
thing. "Te discuss details before one
hns checked up matters completely by
experiment is unwise, for te de se
merely precipitates a flood of useless
argument, discussion and comment, te
which reply must be made. The Ideal
method, when possible, is te solve a
problem completely, as wns done with
the tests of the jet In vacuum, and then
te state results. Thus the discussion
dies before it starts.
Has Unalterable Faith
in Principles and Theory
"Rut while I prefer te avoid sensa
tions, I x ill net back down when I
nni convinced of the soundness of a
physical principle nnd net only is the
moon-sheeting preposition based upon
sound physical principles, but there nre
ether principles just ns fundamental
which are bound net only te lend te
certain refinements, but nlse te results
of still greater interest."
And while the discussions continue,
Dr Goddard works unceasingly en the
model, which lie Is confident will seen
be brought te such perfection as te
permit work te begin en the rocket
which he believes will justify his beliefs
nnd theetles.
