Written Testimony by Donna Shirley
To The House Committee on Science Hearing Entitled
Perspectives on the President's Vision for Space Exploration
Wednesday, March 10, 2004, 10:00 a.m.
Room 2318 of the Rayburn House Office Building.


In my opinion human space exploration is justified by the natural predilection of humans to explore. Humans could conduct science at the moon or Mars but are generally not as effective as robots for this purpose. Humans and robots will be partners in exploration. The International Space Station can be useful as a facility for evaluating human physiology and psychology to prepare for exploration. But if the goal of exploration is to send humans to Mars the moon is of little value in such preparation and, in fact, is a diversion of time and money from the goal. The costs of the program are difficult to evaluate but there appear to be several strategic flaws, including a possibly premature phase-out of the shuttle and premature focus on a specific approach. There is no real information on which to judge the impact of exploration on other NASA missions. I will make several recommendations for revisiting and improving the vision, specifically to include a wide range of "stakeholders" including private space enterprise and non-traditional technologies.


I am Donna Shirley, Director of the Science Fiction Museum and Hall of Fame in Seattle, Washington. I was recently Assistant Dean of Engineering at the University of Oklahoma and before that I retired in 1998 as Manager of the Mars Exploration Program at the Jet Propulsion Laboratory. During my 32-year career at JPL I worked on a number of human exploration missions including participating in the initial design of the space station in the early 1980's and in studies of human missions to the moon and Mars in the 1980's and 1990's. I led two NASA-wide studies in the 1990's, one of which developed a standard process for systems engineering for the Agency1 and another of which analyzed and recommended improvements to NASA's program and project management processes.

My remarks are my own opinions and do not reflect the views of the Science Fiction Museum. However I would like to speak from the perspective of a person who was inspired by science fiction to pursue an engineering career, and who continues to be inspired by the inventiveness of science fiction writers. I will take a cue from Neil Armstrong, who recently used a science fiction theme to talk about the relative roles of humans and robots in space exploration. The popularity of science fiction teaches us that people are fascinated with the idea of exploration. Studies of history, anthropology and primate behavior teach us that humans have a built-in imperative to seek new terrain, just as the crew of the Starship enterprise "explores strange new worlds". Mr. Armstrong pointed out that an early science fiction play, Rossum's Universal Robots, stressed the utility of having robotic laborers to do dangerous, dull or dirty tasks. But science fiction from Buck Rogers to the modern Mars novels like Red Mars shows that people also want to explore the cosmos.

In this context I will address the several questions I was asked by the Committee in the context of the President's Vision as summarized in a White House press release.2

What are compelling justifications for sending humans into space? Does the President's initiative provide adequate justification for sending humans to the moon and Mars?

The quick answer is to the second question is "yes". The justification is that the need to explore is "wired into our DNA". Neuroscience has discovered changes in the brains of adolescents related to their propensity for risky adventures.3 And many people routinely engage in risky behaviors for the thrill of it. Many adults have a desire to go into space and two, Dennis Tito and Mark Shuttleworth, have paid millions to the Russians for the opportunity to visit the ISS. Studies show that thousands of people may be willing to pay six figures for even a sub-orbital ride.4

However, while the justification for human exploration is clear, the justification for the moon as a destination before Mars is not. If the goal is humans on Mars the moon is an expensive and time-consuming delay. So the general vision is good, but the feasibility of the proposed implementation is not clear.

The "moon first" part of the vision is overly specific. There needs to be a process for deciding what should be targets and how to reach them. One of NASA's mistakes is to keep trying to repeat Apollo with Wernher von Braun's 70-year old vision for human space exploration. To what extent would scientific research concerning Mars be aided by a human presence on, or in orbit around that planet?

Humans would do science if they went, but should not go just to do science. For example, studies have shown that semi-autonomous rovers on Mars given direction by humans on Earth are far more effective in exploration (in distance and especially dollar for dollar) than rovers "teleoperated" by humans from Mars orbit.5

The argument that only humans can do science "in situ" is flawed. The lunar "orange dirt" noticed by Harrison Schmitt6, first (and last) scientist on the moon, is used as evidence that robots could never have noticed such a scientifically important find. But the truth is that robots such as Spirit and Opportunity, who are currently on Mars, have a far wider range of senses than a human.7 Robots merely extend human senses both in distance and wavelength. The Mars rovers' instruments can "see" in wavelengths far beyond human sight. Their instruments return data so that scientists on earth can perceive the Martian surface in ways that humans on Mars (unless they were carrying such instruments) could not.

Are the International Space Station and the moon the most appropriate stepping-stones for human space exploration if the ultimate objective is a human landing on Mars? What would be the advantages and disadvantages of a program that was targeted instead on sending a human directly to Mars? To what extent is research on the International Space Station likely to help remove the hurdles to long-duration space flight? The appropriateness of the ISS and the Moon depend on the program objectives, which should be policy decisions based partially on technical feasibility and cost. An informed and open national and international discussion is needed to support these policy decisions.

The lack of widely supported objectives for NASA has led, for example, to its budget being increasingly eroded by Congressional earmarks largely, in my opinion, because there is not a perception of NASA's intrinsic value or purpose

I worked on a precursor to the current ISS in the early 1980's and it was clearly deliberately designed as a jobs program rather than as the most cost-effective solution to human exploration. (And realistically this will always be true of a large federally funded undertaking). Because of the use of Russian launchers to supply the station it is not in a good orbit for staging of assets for on-orbit assembly of missions to the moon or planets. However, the ISS could be useful for studying physiology to prepare for human missions to Mars, and it is important to keep our commitments to our international partners who have invested a large amount of resources and who are waiting to have their hardware installed on the station.

The ISS will help human space exploration if its mission is focused on research on the impacts of living in space on the human physiology and psychology. The President's vision takes this step, however several things are needed to make this work that are not currently in the station design, for example:

  • A centrifuge to explore impacts of partial gravity on recovery from bone loss and muscle weakness. Will astronauts be able to function in the 3/8 gravity of Mars after a several month zero-g passage?
  • Radiation research. The ISS is protected by Earth's magnetic field but the radiation environment on Mars is very severe because Mars lacks a magnetic field and a thick atmosphere.

Phase-out of the shuttle in 2010 will make it very difficult to operate the ISS even if construction can be completed by then. Even if there is not another failure before the end of the ISS there is predicted to be a four-year gap between the end of the shuttle and the availability of the crew exploration vehicle. Human transport can continue to rely on the reliable Russian launchers and landers. However, while European, Russian and Japanese vehicles can supply the station, none of these is designed to bring cargo down, so any large science instruments must either be thrown away or not used if the shuttle is not available. The current plan scraps alternate US cargo carriers.

The Moon is a complete diversion from human missions to Mars. The suggestion that there are materials on the Moon that can be used to build systems to go to Mars is totally unfounded. The Moon has no useful resources for Mars exploration (Water at the poles is problematic, and even if it exists is probably infeasible to "mine" in large quantities.) Everything taken to the Moon must be lifted out of the gravity well of the Earth. Even if resources did exist on the Moon, which would be useful, the mass of equipment to mine them in quantities required for a Mars mission would far exceed the benefit of launching to Mars from the lower lunar gravity.

The high cost of building a lunar infrastructure will divert resources from Mars with no added value for Mars missions because the cost of lifting equipment to Moon will far exceed the benefits.

There is little technology commonality between the Moon and Mars because of the different environments. For example, space suits designed for vacuum will not work in the Martian atmosphere. Landing systems on Mars can make use of the atmosphere unlike those for the Moon. Thermal environments between Moon and Mars are radically different. And so on.

The Moon is a scientifically interesting place in its own right but missions of exploration including the installation of large astronomical telescopes on the far side can be done robotically. Even modern science fiction does not revolve around an economically viable Moon, and previous assumptions of plentiful water on the Moon have been shown not to be true. For example, Heinlein's The Moon is a Harsh Mistress8 was based on an economy, which grew grain using vast stores of underground water.

Helium 3 mined on the Moon and "burned" in a fusion reactor is often touted as a boon for energy production.9 However, both Helium 3 mining and fusion technology are completely unproven, and a positive benefit/cost ratio has not been demonstrated. Furthermore, even if fusion and mining technologies were feasible, they will not be relevant to space exploration in any meaningful time frame.

The President's initiative also mentions Libration Points, Asteroids, etc as destinations, but there appear to be no benefits of these objectives to Mars exploration (or to human exploration) and more justification is needed if they are selected.

Mars is probably the only human-accessible place in the Solar System for sustained human presence

  • The Opportunity rover and the Odyssey orbiter have found past and present water. Future missions will determine locations and quantity of extant water, which may be inadequate to support humans.
  • The moons of the Outer planets have ample water supplies but are too distant and dangerous for humans to explore for generations.
  • Modern science fiction provides reasons and scenarios for a human presence on Mars, for example:

-Red Mars, Green Mars, and Blue Mars (Kim Stanley Robinson)10
-Mars and Return to Mars (Ben Bova)11
-Moving Mars (Greg Bear)12
-Voyage (Stephen Baxter)13

Does the proposed initiative achieve the proper balance among NASA's activities? Particularly, is the balance between exploration, space science and earth science, and between human and robotic missions appropriate?

This question is very difficult to answer because a much more detailed architecture is needed to see what balance is actually being achieved.

The cost of the program needs to be analyzed. The only mission that has been identified for sacrifice is the Hubble servicing. And in fact I believe a robotic servicing mission could be designed and implemented for the price of a single shuttle launch. Technology to grapple with a spinning satellite has been available since the late 1980's14 and it should be relatively simple to keep Hubble running using a robotic Orbital Maneuvering Vehicle15. The OMV would then be useful for on-orbit construction and servicing and is usually included in human exploration mission designs. This approach would not risk humans to service Hubble but also would probably not save any money.

History shows that the real costs of a large program cannot be reliably estimated until 5 to 10 percent of the funds have been expended. However many, many studies of human exploration have been done over the years and if the best were "mined" at least rough estimates should be feasible now 16,17,18,19.

What criteria should be used to determine whether robots or humans should conduct particular science and exploration missions on the Moon and Mars? What missions should only humans conduct on the Moon and Mars?

Humans and robots should be part of an integrated program. It is not humans vs. robots but how a partnership of "metal and mortal" can be most effectively used. Criteria should be extracted from program objectives (why, where, when?) which should be the subject of national and international discussions and debates. A number of studies and publications have addressed this.20,21

Humans will never "only" conduct missions by themselves. Robots will always be necessary as precursors, preparers and partners for humans. As mentioned earlier, robots are extensions of human perception. They currently act as scouts to determine safe and interesting places for people to operate. They will be used to prepare those places for humans by making fuel from in situ resources and building infrastructure. They will support humans by fetching and carrying, exploring beyond the reach of human habitats and transports, and carrying cargo to and from Earth.

If the costs of carrying out the President's proposal increase above what NASA currently projects them to be, would you recommend that NASA adjust the schedule for achieving specific milestones of the President's vision or use the budget authority from other NASA programs not related to the President's vision (e.g., Earth science or aeronautics research and development)?

NASA has not specifically projected the costs of the President's proposal and to some extent this is appropriate since a detailed analysis and design has not been done. However, costs can be inferred.

  • A program cost of about $170B through 2020 can be inferred from the NASA 2005 budget projections.22 This is less than half of the DoD budget for 2005 alone.23
  • A lower bound estimate of about $50B for a single human Mars mission was projected by Robert Zubrin in A Case for Mars. 24
  • Costs of up to $450B (in 1990 dollars)25 have been projected by NASA studies
  • Certainly the $11 or $12B called out for the Crew Exploration Vehicle will only produce a human carrier with no place to go except the ISS. There is no mention of the much larger costs of launch, on-orbit assembly, infrastructure at the Moon and/or Mars, etc.
  • Robotic Mars missions are costing around $400M apiece which is the equivalent of about one STS launch.

The proposed phase-out of the STS in 2010 is extremely risky for the ISS and for exploration. Such a risk led to the dependence on the development of the shuttle to reboost Skylab, the first space station. When the shuttle development did not meet the projected schedule Skylab re-entered the atmosphere and was lost. It is also not clear that any new systems will be substantially safer than an upgraded shuttle.

The question of which missions should be sacrificed to the human exploration initiative is one of public policy. So far the budget appears to continue to support science missions, but the real costs and sacrifices have not been identified past 2005.

The schedule must reflect budget realities and the entire NASA budget would have to be greatly increased to carry out the program. Even the sacrifice of science or technology would probably not provide the resources needed with the current plan.

Observations and Recommendations: Fundamentally the whole approach needs to be re-thought. NASA continues, as it has for its entire existence, to pursue the approach that Wernher von Braun proposed in Collier's Magazine in 1952 - rocket launches, a space station, lunar and Mars bases.26 This approach can be visualized by watching the movie 2001: A Space Odyssey. But times have changed and we need to look at new approaches:

  • New Ideas and Analysis Tools: Since Apollo NASA has had few new ideas about how to explore space. A recent presentation by a young NASA engineer showed exactly the same visualization and study tools27 as my colleagues and I used in the late 1980's and was a rehash of the same concepts we were studying then. 28
  • New technologies: For example, the space elevator, the subject of Arthur C. Clarke's 1956 Fountains of Paradise29 appears to be close to being enabled by structures built with carbon nanotubes and commercial ventures are being undertaken to build one. This is a system that puts a space station in a geosynchronous orbit 23,000 miles above the earth and lowers a cable to a point on the equator. Once this (admittedly expensive) infrastructure was in place it could be used to launch payloads beyond earth orbit. A preliminary design and cost estimates for a commercial space elevator system30 were funded by the NASA Institute for Advanced Concepts which routinely provides seed funding for innovative space exploration concepts. However, none of NASA's human exploration studies are looking at anything creative like the use of a space elevator31. This is not to say that it is the answer, just that new approaches enabled by new technology should be considered.
  • New Economics: Wealthy people are entering the game. Dennis Tito and Mark Shuttleworth are the vanguard of space tourism and many companies are vying to put people in orbit. A new bill to provide regulatory standards has just passed the House of Representatives. 32 Some examples of new launch companies, with their backers, are33:

    -Scaled Composites - Paul Allen
    -Armadillo Aerospace - John Carmack
    -Space Exploration Technologies - Elon Musk
    -Blue Origin - Jeff Bezos

  • New ways of doing business: NASA is proposing a series of "challenge" prizes to stimulate innovative approaches to space exploration.34 However, this is not a substitute for a well-planned program with specific, affordable goals and it still leaves NASA firmly in control. What is the process for infusing the successful approaches into the human exploration program? Or, what is the process for substituting successful approaches for the government-provided elements?

  • New international players: China's Shenzhou program has orbited its first taikonaut. The US needs either to compete or cooperate with the Chinese but the current vision is silent on this.
  • New Culture: NASA has become, over the years, an entrenched bureaucracy shaped by political considerations such as keeping jobs in particular states and Congressional districts. The Columbia Accident Investigation Board stressed the need for culture change35 and NASA is bringing in new personnel, mostly military36, to help with that situation. However, the plans for the initiative which are based on the military model (such as "spiral" and "block development" that are used successfully for aircraft production)37 may not be applicable to the relatively small number of vehicles involved in human space exploration. NASA is attempting to revitalize its workforce 38 and improve its management practices.39

However, the fundamental nature of the civil service-staffed centers will make it very difficult to create real change. Approaches such as converting the centers from civil services to contract organizations such as the Jet Propulsion Laboratory should be explored. Attempts to "privatize" fundamentally non-profit endeavors, such as the United Space Alliance's contract to maintain the shuttle, are merely disguising ordinary government contracting as private enterprise.

A very recent report of a workshop of the National Academy of Science gives guidance for formulating human space exploration objectives. One point that it makes is: "Much of the success of the success of NASA's science programs was attributed to having clear long-range goals and roadmaps that are framed by scientists and periodically reassessed by the science community in the light of new knowledge and capability".40 An example of this is the current Mars Exploration program which sends robotic missions every 26 months to "follow the water" to investigate whether life might have ever existed on Mars41. The current successful Mars rovers are a result of this approach. Unfortunately the President's vision skips over the need for a process to provide goals for the program. Like most other human programs it merely states goals and plunges directly into an implementation strategy. This has been shown over and over to be a flawed strategy as I point out in a paper presented in 2000 at a workshop planning Human Exploration. 42 In this paper I made recommendations that I still regard as important for achieving what the President's strategy lacks:

  • "Customer" Input - for example through "deliberative polling"43 and 44 surveys. This would be from and by people outside NASA and the government, and outside the standard NASA advisors such as the National Academies, and even outside the aerospace engineering and science community. The people are paying for it, shouldn't they have a real say?
  • A flexible, step-by-step approach with planning and redesign in response to things learned, either from science, engineering or economic/policy changes, in other words a "decision tree" approach with options to be exercised based on learning.45
  • Honesty, openness, flexibility, patience and hard-nosed, non-political management46,47.

I recommend that the Committee urge the Administration to create a process for developing a truly fresh approach to the exploration of space. There should be a workshop or series of workshops to infuse non-NASA, non-government ideas into the selection of a vision. Then there should be a study effort over the next year or so to generate new concepts, bring in new players, fully engage the public and develop a set of goals.

The process should include for example

  • Creative individuals, for instance Science fiction writers and movie producers
  • Contestants in University robotics competitions
  • Scientists and engineers
  • Space Entrepreneurs
  • Interested public
  • Formal and informal educators
  • Public Relations people
  • Potential international participants.

Finally, a process should be developed for driving the human space exploration with the results of this study. This will not be an easy task, as government institutions are not accustomed to such an open process.

The Objective: Define a new vision and new architectures and approaches for human space exploration and a program to carry them out. The Science Fiction Museum and Hall of Fame would be delighted to participate in such a process. Thank you.
