FIRST AMONG EQUALS : 1959 A
YEAR OF TROUBLE AND CONFLICT
-
Glennan Cancels Vega
and Reorganizes NASA
-
- Early in 1959, NASA had directed the Jet
Propulsion Laboratory to build a new Vega rocket. Vega was to be
placed atop the Atlas to provide the additional velocity needed to
place a spacecraft in orbit about the Moon or fly it past Mars or
Venus. NASA intended the Atlas-Vega to be the workhorse for lunar
and planetary exploration for the next several years. JPL prepared
a five-year plan for its use. At about the same time, the Air
Force started work on the Agena, a classified upper stage for the
Atlas, to be used to launch reconnaissance satellites. This
Atlas-Agena combination could launch a lunar orbiter or send a
spacecraft by Mars or Venus. Ten months later, NASA found out
about the Atlas-Agena rocket, and, faced with a constrained
budget, arranged to use the Atlas-Agena to launch its lunar and
interplanetary missions.
-
- On December 11, 1959, Dr. T. Keith
Glennan, reorganized NASA and arranged to transfer the Army's
Development Operations Division * and the Saturn Project to NASA. No longer needing
the Vega, Glennan also canceled that project, much to the
consternation of the several hundred JPL engineers who were
working on it and the scientists who were building instruments to
fly on the six test flights of the Atlas-Vega.
132 These actions
increased the tension between JPL and NASA Headquarters, added to
the irritation and confusion of space scientists, and helped force
Newell to abandon his hybrid space science organization, establish
a strong space science organization at NASA Headquarters, and
bring the process for the selection of space scientists into NASA
Headquarters.
-
- On December 16, 1959, Richard E. Horner,
associate administrator of NASA, wrote to Dr. William H.
Pickering, director of JPL, to inform him that the Vega Project
had been canceled. In the same letter, Horner assigned Pickering
the job of planning and executing NASA's lunar and planetary space
exploration program. 133 Pickering promptly
seized upon this new assignment to resolve his conflicts with
Newell over the selection of scientists for lunar and planetary
missions. He requested Silverstein to remove Jastrow as chairman
of the Working Group on Lunar Exploration and replace him with Al
Hibbs, director of the Space Science Division at JPL.
134 Silverstein
ignored Pickering's request and on December 21 sent him a letter
that started with the words: 135
-
- Based on a study by the several groups in
the Headquarters staff participating in the lunar and deep space
program, the following tentative flight program and mission
designations have been established as a starting point for
determining a post-Vega program.
-
- Silverstein's letter specified five lunar
missions, two missions to Venus in 1962 and two to Mars in 1963.
It directed the laboratory to develop a system to transmit high
resolution pictures of the lunar surface back to the Earth.
Silverstein's letter made it clear that NASA Headquarters would
formulate the lunar and planetary program and decide which
experiments would be flown. He notified Pickering that several
people from his staff would visit JPL on December 28 to work out
any problems that JPL had with the program.
-
-
- A Crucial Meeting
at JPL
-
- With all these issues coming to a rolling
boil, Newell and three members of Silverstein's staff flew to
California on December 27, 1959 to meet with Pickering to resolve
the problems between NASA Headquarters and JPL. The following
material is based on the lengthy memo that Newell prepared after
his return to Washington.136
-
- Using Silverstein's December 21 letter as
an agenda, the group considered problems of spacecraft, launch
vehicles, and schedules for lunar missions and agreed that JPL
should immediately start work on what would become the Ranger and
Surveyor missions to the Moon.
-
- After a long morning session, Newell,
Pickering, Goddard, and Hibbs held a rump session to battle out
the method of selecting scientists to conduct experiments on JPL
lunar and planetary missions-issues raised by Pickering's letter
to Silverstein. The group agreed on a policy for the selection and
role of space scientists. Under this policy, NASA would establish
a mission and Silverstein's Office of Space Flight, in
collaboration with JPL, would select a tentative group of
scientists for it. They would select more experiments than the
spacecraft could carry. Subsequently, the excess scientists and
their experiments would be eliminated prior to Silverstein's
approval of the final selection. The experimenters would build
prototype models of their experiments that JPL would then examine
to determine if they were suitable for flight. With the advice and
concurrence of Newell's office. JPL would make the final selection
of experiments and experimenters for the mission. JPL would build
the experiments. or directs contractor to build them, based on
specifications prepared by the experimenter.
-
- This policy, as described in Newell's
memo, would have made NASA Headquarters responsible for the
initial selection but allowed JPL to determine if the experiment
and the spacecraft were technically compatible. Thus, during the
evaluation process, JPL could eliminate experiments it did not
like. In addition, the policy would have made JPL responsible for
building the flight version of the experiment, one of the
procedures Berkner had complained about in his report to the
President's science advisor. The policy would not have cut the
scientist completely out of the fabrication process: he was to
"assist JPL."
-
- Experienced space scientists did not like
this kind of arrangement because they knew they had to build their
own apparatus to be sure the experiment made the measurements to
the accuracy they wanted. Eventually, they would win the right to
build their instruments but they did not win it in this particular
meeting at JPL. One group, however, the University of Chicago
Group under Dr. John A. Simpson, after their disastrous encounter
with STL's engineers on Pioneer insisted upon building their own
flight instruments and overseeing their integration into JPL
spacecraft.137 In contrast to
JPL, Goddard, the other space flight center, insisted from the
beginning that scientists should build their own flight
instruments, deliver them to Goddard, and then work with the
project team to ensure that their instruments were properly
integrated into the spacecraft.
-
- According to Newell's memo, the group next
considered the question of the chairmanship of the lunar science
committee. While the chairmanship and membership of a committee
were the immediate problems, the issues ran much deeper. A NASA
Headquarters Lunar Science Committee existed. It was chaired by
Dr. Robert Jastrow, theoretical physicist at Goddard. To Newell,
Jastrow represented NASA Headquarters, not the parochial interests
of the scientists at Goddard. To Pickering, Jastrow represented
the Goddard scientists clamoring for space for their experiments
on JPL missions. Such an arrangement-a Goddard scientist chairing
a committee that planned the scientific program for JPL's lunar
missions-was unacceptable to Pickering. Furthermore, Jastrow's
committee had just recommended gamma-ray experiments for a lunar
orbiter, a mission that, at that time, was not even in NASA's
space science program. Clearly, to Pickering, a committee that was
not close enough to the program to know what missions were
scheduled could not be much help to JPL. Furthermore, as chairman
of the committee, Jastrow reported directly to Newell at
Headquarters.
-
- Pickering cited Horner's week-old letter,
which assigned JPL the responsibility for planning and executing
the lunar program, and proposed, as we have noted, that Hibbs
replace Jastrow as chairman. Newell disagreed with Pickering's
proposition: overall program planning was the responsibility of
Headquarters. He, Newell, had already taken steps to set up such a
committee, which he would chair. It would be an internal NASA
committee and JPL would be invited to name a member. The group
discussed the matter, and finally Newell agreed that a Goddard
scientist should not chair a committee that established the
scientific objectives or picked the scientists for JPL missions.
Pickering agreed to a chairman from Headquarters and to limit the
membership to people from NASA and JPL, while both agreed that it
was important that the views of lunar and planetary scientists be
heard by the committee.
-
- Although neither Newell nor Pickering got
exactly what he wanted out of the discussion and later events
changed some of their agreements, this meeting did lead Newell to
begin to abandon his hybrid space science organization and
ultimately to formulate the policies and procedures that NASA has
used for several decades years to select space scientists.
-
- Newell returned to Washington and typed
out a ten page "Memorandum for the Record" that described the
meeting and the agreements he had reached. He signed about thirty
letters and memoranda and went home to welcome a new year and a
new decade of space science.
-
- Lessons Learned in
1959
-
- Abe Silverstein and his team at NASA
Headquarters learned several important lessons about space science
during NASA's first faltering year. They learned that a space
science program had to be broken into discrete missions and each
mission assigned to a specific center. Each mission should be
assigned to a specific scientific discipline or possibly, to two
or three scientific disciplines, provided they all had similar
requirements for the orientation of the spacecraft and the orbit
in which it traveled. Each mission must have a group of scientists
dedicated, for the duration of the mission, to accomplishing the
scientific objectives. Each mission must have a project scientist
who could work with the scientists selected for the mission and
with the project engineering team responsible for developing,
launching and operating the spacecraft. The project scientist was
needed to understand and interpret the legitimate requirements of
the scientists to the project team and to interpret and explain
the project team's requirements to the scientists. One person, a
project manager, must oversee the whole operation, get the
instruments, spacecraft, and launch vehicle built, tested, and
assembled and ready for launch. The project manager and the
project scientist must work together to accomplish the objectives
of the mission. Silverstein's team learned that the scientific
objectives, technical requirements, and cost of a space science
mission were interdependent and could not be separated at any
management level.
-
- At the end of 1959, it was clear that NASA
needed a better process, and as well-documented process, for
selecting scientists for its scientific missions. Competition
among scientists was fierce. Academic scientists did not trust
their competitors on the Space Science Board or those at the NASA
field centers to make a fair selection. Scientists at JPL and at
Goddard did not trust the Space Science Board or each other to
make the selections for the missions assigned to their respective
center. NASA needed a process that would establish the United
States as the leader in space science and that NASA and academic
space scientists, the President's Science Advisory Committee, and
the Space Science Board all had confidence in. It also had to be
one that NASA center directors, project managers, and procurement
officials could accept.
