New starts and tough choices at NASA.
Now being worked over behind locked doors at the Office of Management and Budget The Office of Management and Budget (OMB), formerly the Bureau of the Budget, is an agency of the federal government that evaluates, formulates, and coordinates management procedures and program objectives within and among departments and agencies of the Executive Branch.

Waiting in the wings for funding, however, have been plans for three major scientific programs at the National Aeronautics and Space Administration National Aeronautics and Space Administration (NASA), civilian agency of the U.S. federal government with the mission of conducting research and developing operational programs in the areas of space exploration, artificial satellites (see satellite, artificial), , and interest in all of them has been high enough that they are already atypically prominent topics of discussion.

Missing from the plan, the sources say (as does an article in the Sept. 16 Aviation Week), is the one candidate program that would be sent beyond earth-orbit. Called the Comet Rendezvous/Asteroid Flyby fly·by also fly-by

But more than that, CRAF is the next item in the plan proposed by the NASA-chartered Solar System solar system, the sun and the surrounding planets, natural satellites, dwarf planets, asteroids, meteoroids, and comets that are bound by its gravity. The sun is by far the most massive part of the solar system, containing almost 99.9% of the system's total mass.

"This plan," says Laurel Wilkening, chair of the American Astronomical Society's Division for Planetary Sciences The Division for Planetary Sciences (DPS) is a division within the American Astronomical Society devoted to solar system research. It was founded in 1968. The first organizing committee members were: Edward Anders, L. Branscomb, J. W. Chamberlain, R. Goody, J. S. , "was devised at a time, several years ago, when it appeared that the United States was going to drop out of planetary exploration completely." Accordingly, the SSEC proposed a series of missions designed to provide continued exploration of the solar system at reduced cost through the use of standardized spacecraft designs and other approaches.
But the essence of the plan, a radical departure from NASA's previous planetary programs, was its requirement of a series. The absence of CRAF is "more than the loss of an individual mission right now," says SSEC chair David Morrison of the University of Hawaii (body, education) University of Hawaii - A University spread over 10 campuses on 4 islands throughout the state.

(temporarily at the University of Arizona (body, education) University of Arizona - The University was founded in 1885 as a Land Grant institution with a three-fold mission of teaching, research and public service. in Tucson). "It is the apparent abandonment of a plan that previously NASA NASA: see National Aeronautics and Space Administration.

Independent U.S. has praised and adopted."
That is not to say, however, that it was officially adopted in the language of NASA's budget. In fiscal 1985, the budget included the initiation of a Mars-orbiting mission to be built around a newly designed spacecraft called a "Planetary Observer," first of the SSEC's proposed multi-purpose craft. Conspicuously absent from that budget, however, was a budgetary "line item" for development of the Observer itself. "The acceptance of the [Mars mission] by itself and the failure to include a [Planetary Observer] line item is a bad development," said Clark Chapman of the Planetary Science Institute in Tucson at the time. "It seems to me that NASA has not accepted the SSEC plan."
Yet the mission itself stayed in the budget, as has its predecessor on the SSEC list, a spacecraft to make improved radar maps of the surface of Venus. "In every step so far," says Morrison, "with the exception of phrasing that as a long-term commitment, [NASA] has in fact given us what was asked for in the timetable laid out in the SSEC's report. And they have repeatedly praised that report, and even held it up to other science groups as 'this is the model of the thing to do'--you know, discipline and modest requests and so forth. So this year, because of [NASA's] actions over the last three years, the planetary budget for fiscal 1986 is actually up to the level called for in the core program of the SSEC. Therefore, all it needs to do is continue at a level funding rate, and we're okay. To not start CRAF this year is the first departure from the SSEC plan."
CRAF was originally to be sent to a comet named Kopff, which was then changed to Comet Wild 2 to accommodate a later launching. Delaying the mission's budgetary start-up until fiscal 1988, says Wilkening, would require choosing still a different target comet such as Tempel 2. A visit to Tempel 2, she says, would also be a more expensive mission, because it would take more time and more propulsion for the spacecraft is to be not another Planetary Observer, but the SSEC's second proposed design, called Mariner Mark II Mariner Mark II was NASA's planned family of unmanned spacecraft for the exploration of the outer solar system that were to be developed and operated by JPL between 1990 through the year 2010. (MkII). Delaying the start of the MkII, says Wilkening, would also have the "ripple effect ripple effect Epidemiology See Signal event. " of delaying several SSEC missions to follow. Furthermore, adds Morrison, there would be "a real problem" at Jet Propulsion Laboratory “JPL” redirects here. For other uses, see JPL (disambiguation).
Jet Propulsion Laboratory (JPL) is a NASA research center located in the cities of Pasadena and La Cañada Flintridge, near Los Angeles, California, USA. in Pasadena, Calif., where the MkII is to be developed and which would be the mission's control center. The Mars mission has been timed in the SSEC's planning to save money by employing the teams already assembled for the Galileo Jupiter mission (to be launched next year). "And if you can't pick them up on Martiner Mark II," Morrison says, "you run the real risk in today's market of losing them to 'Star Wars' or something. And then where would you be?"
The two new NASA programs that are said to be in the FY'87 NASA budget sent to OMB, however, also stand to affect more than their own, individual spacecraft.

Topex is also to include a French radar-altimeter named poseidon as well as serving as what NASA's William Patzert calls a "centerpiece" of the ongoing World Climate Research Program. Says Patzert, "I guess the grim reality is that if TOPEX slips one more time, other initiatives within NASA will have higher priority -- for instance, the multi-instrument polar-orbiting platforms that might be part of the space station activity. ... Perhaps some of these other, larger, more elaborate initiatives in terms of earth and ocean remote sensing will start to have more priority, rather than single dedicated missions."
The other program so far included for fiscal 1987 is even more elaborate, involving three spacecraft from the United States (NASA's), two from the European Space Agency European Space Agency (ESA), multinational agency dedicated to the promotion, for exclusively peaceful purposes, of cooperation among European states in space research and technology. and one from Japan. Called the International Solar-Terrestrial Physics (ISTP ISTP International Solar Terrestrial Physics (platform)

It, too, has been through the budget wars, but last month, the National Research Council's Committee on Solar and Space Physics identified ISTP as the highest-priority item already planned but yet unfunded in a report on envisioned solar-system physics programs through the year 2000.
International cooperation is seen by some researchers as particularly important in the sort of physics arena that includes ISTP, because NASA three years ago dropped what would have been the U.S. half of a joint mission with the European Space agency to send a pair of spacecraft over the sun's poles. (The surviving European entry, called Ulysses, is to be launched by the space shuttle next May.)
"The problem that we have right now is that, relative to the Europeans and the Soviets, NASA is to some degree marking time," said Morrison two weeks ago. He was speaking at the time in the context of interplanetary missions such as CRAF, but his words were not dissimilar to sentiments that have been echoed by scientists in other fields of space science as well. "We are moving," he said, "from a situation in which the United States had the clear international leadership in this area to a situation where we may not be perceived by our potential partners as a reliable partner for such exploration."
