Foreword 
This volume in NASA’cso ntinuing series of  annual chronologies records the 
events of  1973. The 15th year of the space agency’s existence is memorable 
to the public as the Year of  Skylab and the Year of  Jupiter. The nation’s 
first earth-orbital laboratory was launched. Beginning with a dramatic 10-day 
fix-it effort that  restored  Skylab’s  capability to generate electrical  power, 
three three-man crews rendezvoused and docked with the space laboratory. 
Their total of  12 351 man-hours in space supported the feasibility of pro- 
longed manned space flight.  Even more  impressive were the volume and 
quality of  experiment results. The sophisticated battery of  telescopes in the 
Apollo Telescope Mount produced 182 842 frames of  film and 941 hours of 
manned viewing of the sun. The earth was not neglected either. Orienting the 
laboratory toward the earth, astronauts took a total of  40 286 frames of 
earth-resources photographs. Electric furnace experiments with zero-gravity 
manufacturing offered interesting possibilities of new industrial processes that 
cannot be achieved in earth gravity. Assimilation of the knowledge contained 
in the mass of data is still continuing. 
As the year closed, Pioneer 10 swept by the planet Jupiter after a 21-month 
flight that traversed a billion kilometers. Passing through the intense radia- 
tion surrounding the largest planet in our solar system, Pioneer 10 sent back 
300 closeup photographs of  the planet and its inner moons, along with other 
measurements of  the swirling atmosphere and its massive Red Spot and of 
the magnetic, radiation, and electrical environments. Even as it returned the 
data-much  of which contradicted previous theories-Pioneer  10 was heading 
outward toward the orbits of Saturn and Pluto. In the late 1980s it will be- 
come the first man-made object to leave the solar system and voyage into 
interstellar space. The events of  Skylab and Pioneer were only the most 
visible  successes of  1973, however;  many  other important events accom- 
plished their objectives with less notice. 
On a smaller scale, but particularly important to a few, was the announce- 
ment of  a new heart pacemaker developed from electronic components and 
batteries originally designed for use in space. The new model was recharge- 
able, thus eliminating the need for periodic surgery to replace the earlier 
instrument. 
Uses for the vast amount of  data from the Earth Resources Technology 
Satellite Erts 1 multiplied as it completed its first year in space in July 1973: 
planning land use, managing water resources, estimating crop yields, inven- 
torying timber, exploring for minerals and petroleum. The practical benefits 
from this and similar programs seem at this writing almost limitless. Indeed, 
the principal problems are no longer the acquisition of such data, but rather 
its rapid and economical reduction int9 usable forms. 
In aeronautics, work went forward on a number of programs: digital fly- 
by-wire, which will significantly improve aircraft control; the supercritical 
wing, which provides significant fuel savings; reduction of  noise and pollu- 
tion; and hydrogen injection to increase efficiency and reduce pollution from

gasoline engines. Collectively these efforts promise safer flight, fuel economies, 
and less damage to our environment. 
Thus on most counts NASA activities seemed to bear out the Administrator’s 
statement in late 1973 that NASA was providing more emphasis on becoming 
L<m  ore like one of the service agencies of the government.” 
Altogether 1973 was a productive year, punctuated at times with excite- 
ment. And while real achievements were being realized, plans were being 
laid for subsequent programs,  and this volume offers specific information 
about both.

A brief, chronological account of  key events of  the year in space and in 
the atmosphere, Astronautics and Aeronautics, 1973 records dates, actions, 
hardware, persons, scientific discoveries; plans, decisions, achievements, pre- 
liminary evaluations of  results, and samples of  public reaction and social 
impact. The volume is offered for reference use within the Federal Govern- 
ment and by the public. It should be of use to present and future scholars in 
a variety of disciplines. 
The sources, identified by abbreviations that are explained in Appendix D, 
were those immediately available in NASA and other Government agencies, 
the Congress, and the professional societies, as well as the press. Contradictory 
accounts have been resolved and doubtful ones verified whenever possible by 
querying participants. Cross-references are given in the text, and the detailed 
index will aid in tracing related events through the year. The index also 
serves as a glossary of acronyms and abbreviations. 
General editor of the volume was the Publications Manager of  the NASA 
Historical Office, Frank W. Anderson, Jr., and the technical editor was Mrs. 
Carrie E. Karegeannes. Archivist Lee Saegesser collected current documenta- 
tion. The Science and Technology Division of the Library of Congress, under 
an exchange of  funds agreement, drafted monthly segments in  comment 
edition form, which were circulated for corrections, additions, and use. At 
the end of the year, the entire manuscript was reworked to include comments 
received and additional information that was not available when the monthly 
segments were prepared. At the Library, Patricia D. Davis, Nancy L. Brun, 
Shirley M. Singleton, and May Faye Johnson carried principal responsibility. 
Arthur G. Renstrom of the Library prepared preliminary indexes for the 
first six months; Informatics TISCO, Inc., prepared the detailed index for the 
annual volume. 
Appendix A, “Satellites, Space Probes, and Manned Space Flights, 1973,” 
Appendix B, “Chronology of Major NASA Launches, 1973,” and Appendix C, 
“Chronology of Manned Space Flight, 1973,” were prepared by Leonard C. 
Bruno of the Library of  Congress. Appendix D,  “Abbreviations of  Refer- 
ences,¶’w  as prepared by Mrs. Karegeannes. 
Without the assistance of many persons throughout NASA and other Federal 
agencies,  the content of  this volume  would be less reliable and complete. 
Comments, additions, and criticisms are always welcomed by the NASA His- 
torical Office.

January  1973 
January 1:  NASA had scheduled 15 spacecraft launches in 1973 from Ken- 
nedy Space Center, Eastern Test Range, and Western Test Range, KSC 
announced. Launches would include four Skylab missions, three of them 
manned;  Intelsat-IV F-6,  F-7,  and F-8  for Communications Satellite 
Gorp.; Pioneer-G to fly by Jupiter; Canada’s Telesat-B comsat; RAE-B 
Radio Astronomy Explorer;  United Kingdom’s  Skynet 11-A  comsat; 
Mariner mission to fly by Venus and Mercury; ITOS-E  Improved Tiros 
Operational Satellite; ERTS-B  Earth Resources Technology Satellite ; and 
AE-c  Atmosphere Explorer. ( ICSC Release 1-73) 
* NASA and Soviet space officials had agreed to permit representatives of the 
U.S. and U.S.S.R. to observe and advise in Apollo and Soyuz flight con- 
trol rooms during orbital phase of  July 1975 joint mission,  Aviation 
Week & Space Technology reported. No agreement had been reached to 
permit U.S. observers at the Soviet launch site during liftoff of Soyuz 
spacecraft. [See March 15-30.]  (Av Wk,1 /1/73,  13) 
* An Aviation Week 8 Space Technology editorial noted the aerospace indus- 
try forecast for 1973 was for continuing improvement “across the entire 
technical spectrum.’’ The year  1971 had bottomed  out the 1969-1970 
recession and provided the “first tangible evidence of  upswing.”  The 
year 1973 should continue the uptrend “on a modest but solid curve.” 
Industry had been “under increasing pressure from Congress, the Penta- 
gon and the taxpaying public for the last five years to improve its 
manageria1 efficiency and the reliability performance of its products. The 
pressure has now accumulated to the point where the industry must re- 
spond, both  internally  in  cleaning its  own  house  and  mounting  an 
aggressive campaign for government contracting reforms to match, or 
face the very real spectre of nationalization in the public mood that may 
well prevail four years hence.”  (Hotz, Av Wk, 1/1/73,  11) 
* The “deeper meaning” of  Apollo 17 (Dec. 7-19,  1972), the last manned 
lunar landing mission  in the NASA  program, was discussed by author 
William I. Thompson in a New York Times article: The mission had 
represented a “sunset” of rocket technology. “Apollo 17 turned the night 
into day, but elsewhere smalIer lights were going on as men began to 
discover relationships between consciousness and the growth of  plants 
. . . , between enzyme change and faith healing. . . , and between mind 
and matter in psychokinesis.  . . . The space program was an important 
scaffolding, but now that the building of  the new human culture is up, 
we no longer need the scaffolding.” To spend a fortune on rockets now 
“would be the same as spending a fortune on dirigibles in 1916. There 
are other forms of space travel to be invented, and these forms are more 
likely to spring from the new paradigms emerging in science than from 
the hardware of the old technology. The era of the rocket has climaxed 
in Apollo 17; if we push on and ignore the sense of an ending, we shall 
find only the bitterness and disappointment of the anticlimax.”  (NYT, 
1/1/73,  3 :13)

January 2  ASTRONAUTICS AND AERONAUTECS,  1973 
January 2:  Dr. James C. Fletcher, NASA  Administrator, expressed gratifi- 
cation in his monthly letter to the staff “with NASA’es xcellent perform- 
ance in 1972, and with the successful transition . . . from the completed 
programs of the Sixties to the new programs and new challenges of the 
Seventies. In 1972, Phase I of  the national space effort of  the United 
States was completed and Phase I1 well begun.” 
NASA’fisr st year with all launches and missions successful underlined 
that it was NASA’csu stom “to do the unprecedented and then quickly 
make it routine.” Zero failures could now be the goal year after year. Dr. 
Fletcher also noted that of  18 space launches in 1972 half had been for 
other organizations or countries, with 8 being reimbursed. 
On another “important front,” the NASA-wide payload cost-reduction 
campaign begun in 1972 had gone well, with valuable suggestions from 
Centers and contractors. The effort “was not a routine cutback exercise 
and not a threat to anyone’s security. It is, instead, a creative effort to 
expand our usefulness even though funds are limited. And you can be 
sure it has a lot to do with NASAl’osn g-range survival as the instrument 
of the US. Government to handle most kinds of space and aeronautical 
R&D and other related assignments.” (NASA Activities, 1/15/73,  2-3) 
Dr. Edward E. David, Jr., Presidential Science Adviser, resigned to return 
to private industry. The former communications systems scientist at Bell 
Telephone Laboratories,  Inc., had served as Director of  White House 
Office of Science and Technology for 28 mos and had instituted reorgani- 
zation of the Federal science complex. The New York Times quoted White 
House sources as saying the resignation was prompted by disappointment 
that his advice had not been heeded by the Nixon Administration. Fed- 
eral support  for  science and technology  expressed as percentage  of 
budget outlays for research  and development  had reached the lowest 
point since latter years of  the Eisenhower Administration. The White 
House had declined comment on the resignation and had not released 
the text of Dr. David’s letter to the President. (Lyons, NYT, 1/3/73,  1) 
Grumman American Aviation Corp. was formed by the merger of  Grum- 
man  Corp.’s  general-aviation  interests  and American  Aviation  Corp. 
Grumman’s Gulfstream 1 and 2 and Ag-Cat program assets were trans- 
ferred to American Aviation Corp. in exchange for shares in American. 
Corporate headquarters of the new company would be in Cleveland, Ohio, 
with Grumman President E. C. Tow1 as company Chairman and Ameri- 
can President and Chief Executive Officer R. W. Meyer as President. 
(Znteravia, 4/73, 301; Grumman Corp pro) 
January 3:  President Nixon accepted the resignation  of  Dr.  Edward  E. 
David, Jr., as Science Adviser and Director of  Office of  Science and 
Technology [see Jan. 21. (PD, 1/8/73,  10) 
* NASA  planned to spend up to $100 million during the next five years on 
the post-Apollo lunar science program to extract information from 385 
kg (850 Ibs) of lunar samples, 30 000 photos, and “miles” of  magnetic 
tape from six Apollo lunar landing missions, the New York Times re- 
ported. Director Anthony J. Calio of  Manned Spacecraft Center Office 
of Science and Applications had said in an interview that recommenda- 
tions in an October 1972 report of the Lunar Science Institute were being 
followed  in much  of  MSC’S  planning,  but  the  MSC  Lunar  Receiving 
Laboratory would be closed on completion of Apollo 17 sample process- 
ing.  The sample collection  might be  divided  for  storage at another 
Government facility as a “precaution.” The LRL report had said preser-
