Abstracts

The Environment

Noel Hinners will rhapsodize on the major challenges he had as a center director in enabling the science and engineering implementation of the Cosmic Background Explorer (COBE). The internal Goddard Space Flight Center environment for COBE was unusual in that it was managed by the Engineering Directorate to provide essential hands-on training to the engineers. The science and engineering aspects of COBE were in and of themselves challenging. These were exacerbated by episodic changes in launch vehicles. Combined, this led to much more staffing than originally envisioned, further stressing the center. Looking outward, there were the challenges in dealing with NASA Headquarters (13.7 miles distant) and the pressures to remain on the Space Shuttle rather than switching back to an expendable launch vehicle. Sanity won.

The Mission

John Mather will discuss the challenges of organizing and running two teams: the COBE science team and the James Webb Space Telescope (JWST) science team. COBEs three instruments presented unique challenges. Each instrument had its own principal investigator (PI), so there were different executive styles, which will be compared. Also, the Science Working Group was constituted as co-investigator on all three instruments, so there were team-level challenges and significant conflicts to be managed, as documented in the book The Very First Light: The True Inside Story of the Scientific Journey Back to the Dawn of the Universe.

Two of the PIs were in house at Goddard, leading to excellent communication with the engineering teams, while one PI was external at Berkeley, leading to significant difficulties that had to be managed by recruiting an in-house deputy PI. The special situation of a government team being led by an external investigator required serious negotiation, since NASA does not delegate management of its civil service staff to outside people. The whole science team played a major role in project decisions regarding improving the instrument sensitivity for the differential microwave radiometer (DMR) instrument (a good thing, otherwise the DMR would not have detected cosmic fluctuations).

On the JWST observatory, a strategic mission for NASA, the European Space Agency, and the Canadian Space Agency, the science team is advisory, and team members are not co-investigators on all the instruments. The comparison will be illustrative.

The Project

Michael Ryschkewitsch will discuss several aspects of program management for robotic missions, including using a systematic approach involving three phases: determining evaluation, validation and verification, and benchmarks; defining responsibilities of line and project management in the successful organization; and handling the people problem during the formulation and implementation phases. Also to be discussed is what is involved in creating a work agreement, including predicting management success, achieving program excellence, and understanding root causes, systems engineering and its various phases, NASA governance, and requirements.

Abstracts

Principal Investigator

An overview of the building of a PI-led team for a NASA mission will be presented as well as the important relationships the PI has with the PM and systems engineer. PI traits, qualities, and responsibilities will be addressed and will be followed by a discussion of how a PI chooses the science team and structures the mission team. Other topics to be addressed include developing a clear Mission Requirements Document and the process and importance of descoping. Finally, the importance of the total involvement and perseverance of the PI in following the mission development will be discussed along with key indicators of mission development status (e.g., the use of planned versus actual monthly milestone accomplishments).

Project Scientist

The presentation will cover experience and lessons learned as project scientist during the Mars Odyssey mission and will describe the duties of a planetary mission project scientist.

Project Manager

The multitude of roles played by the project manager (PM)ranging from daily technical management to project psychiatristwill be discussed. The criticality and complexity of the relationships between the PI and PM, PM and the mission systems engineer, and PM to NASA will be discussed. The process of building the teams infrastructure in the new world of earned value management and joint confidence level will also be presented. Examples of real-world problems and solutions from IMAGE, New Horizons, and other missions will be used to illustrate points throughout the presentation.

Systems Engineering

Systems engineering plays a critical role in space-mission development and is the right hand of the PI and the PM to ensure a low-risk, affordable achievement of the missions technical objectives. The role of the systems engineer in complex technical development is not to act as a clerk to manage a requirements database, or merely an analyst to calculate mass and power margins, but is the technical visionary that leads vertical and horizontal design and integration of the missionespecially across the major interfaces of science instruments and ground and mission operations. Roles and responsibilities of the systems engineer within the PI-led team and the essential leadership qualities, experience, and system view that past successful PI missions have practiced will be discussed, as well as the challenges of the current state-of-the-art in space-mission development that face todays systems engineers.

Contractor Team

Industry is a valuable member of the PI-led mission team and provides a different perspective from project leadership and science members. The need to embed compelling science coupled with the cost capped execution model creates a set of constraints that drive best-fit solutions. The experienced industry partner often becomes the voice of reason that seeks to accommodate the project/NASA center and PI science needs, while keeping an eye on execution risk. Industry is motivated to push for the early flow-down of science requirements, the development of a mission concept that balances complexity and cost, and prudent application of new technology that enables win discriminators. When well executed, the competed PI-led mission team effectively bonds together during the CSR and site visit activities. Examples will include Phoenix and MAVEN, including experience gained from problems and the ways they were successfully solved.

Abstract

Stardust and Stardust New Exploration of Tempel-1 (NExT), led by principal investigators Don Brownlee and Joe Veverka respectively, provide an impressive array of forefront science results. Samples returned from Stardust have changed our concepts of the composition of comets. As with Apollo samples, new results will continue over the next many decades as both new analytical techniques and scientific questions arise. Stardust NExT provided an economical opportunity to use a valuable space asset to extend our understanding of the comet Tempel-1 and to investigate the crater left by the earlier NASA Deep Impact mission.

The Stardust sample return mission was selected as the fourth mission of NASAs Discovery Program in December 1995. Phase B began December 1995, and Phase C/D began nine months later. Stardust launched on February 7, 1999, and the sample-return capsule (SRC) landed at 3:00 a.m. on January 15, 2006, at the Utah Test and Training Range.

Mark Saunders was the Discovery program manager at NASA Headquarters at the start of the program and set the mission-success criteria and fee structure for Lockheed Martin. Phase C/D was twenty-eight months to launch. The development was extremely mass constrained in the middle of Phase B when an error was discovered in the committed launch vehicles payload capability366 kg to 312 kg. The spacecraft avionics and software were developed in parallel with the 98 missions Mars Climate Orbiter and Mars Polar Lander. The SRC was developed from a blank sheet with a new heat-shield material in about two and a half years.

After launch, the NASA Earth-entry requirements changed and forced a redesign of the approach trajectory. Risk tolerance had also changed since launch, forcing a re-review of all risks associated with Earth return. After successfully completing the Stardust mission, the Stardust New Exploration of Tempel-1 Discovery mission of opportunity was initiated with spacecraft recontact and verification of full operational status in 2007. The spacecraft encountered Tempel-1 on February 14, 2011, sending home seventy-two images of the nucleus, including the Deep Impact crater. The final maneuver to propellant depletion was executed on March 24, 2011.

Roles of the Program Scientist and Program Executive

The Science Mission Directorate (SMD) at NASA Headquarters has designated the program executive (PE) as the key technical and programmatic point of contact for SMDs projects. As such, the PE provides a vital link between supporting the execution of the project and the top-level management and oversight responsibilities of the Directorate. In this position, the PE takes on a dual persona as both the Headquarters advocate for the project, but also The Enforcer of NASA project management rules and requirements. Recognizing these roles and understanding how they interrelate will aid the project team in getting comfortable when interacting with their PE, which can add great value to the project.

Working in the Discovery Program Office

The primary responsibility of the Discovery Program Office is to ensure Discovery missions are successful in achieving their science objectives. We do this by working with the principal investigator (PI) and project team to manage the cost, schedule, and technical elements of the project and by guiding them through the various processes that make up the life cycle of these missions. This presentation will provide an overview of the Discovery Program Office organization, functions, and approach to working with the PI, the project team, and SMD to ensure the success of Discovery missions. The intent is to provide guidance on working relationships and processes, as well as lessons learned by the program office from the management of multiple Discovery, New Frontiers, and Lunar Quest missions. Expectations of the PI on a PI-led mission will also be addressed.

Abstract

Performing to committed cost has forever been a space and Earth science goal, along with attaining technical and scientific goals. Emphasis on the cost element, however, has greatly increased over the past decade. This includes enhanced external oversight of NASAs cost performance by the Government Accountability Office, Office of Management and Budget, and several Hill committees. It is clearly in our own best interest to understand the rationale for that emphasis and pay special attention to increasing our ability to perform to committed cost.

Successful project-resource control on NASA projects is grounded not just in the application of specific cost monitoring and control techniques, but also in a thorough understanding of both the external and internal environments in which NASA projects are approved, formulated, developed, and operated. NASA is a part of the discretionary component of the federal budget and operates in a very constrained budgetary environment. It is therefore imperative that projects be managed within their approved budgets. The Science Mission Directorates (SMD) cost-performance requirement is very simple: Meet your commitment as represented by your proposal.

In the continuing effort to improve our processes for selecting and managing our projects, the agency and SMD have instituted a number of new processes designed to improve communication, understanding, and trust between the project, the supporting institution, SMD, the agency, and our sponsors and stakeholders. These processes may be self-imposed or in response to external requirements (e.g., legislation). The basic pattern of processes is driven by the life-cycle review process and is augmented as required. The project life-cycle review process and most of these processes are presented in the current version of NASA Policy Directive 7120.5, NASA Space Flight Program and Project Management Requirements, although some are evolving and are yet to be fully documented and implemented.

The origin for all these processes is the desire of the Directorate and the agency to establish and improve its credibility with our sponsors and stakeholders by demonstrating our ability to clearly define the cost, schedule, technical requirements, and risk associated with our major programs and projects at the commitment milestone (KDP-C) and to execute those activities within the commitments we make to the sponsors and stakeholders.

Abstract

This presentation will illustrate the techniques critical to managing resources of science projects led by principal investigators (PI). Those involved in Viking, Cassini, and past Mars missions will share their experiences about managing resources and margins successfully.

Critical resources traditionally include mass, power, schedule, cost, and, perhaps more provocatively, risk. (Risk is a resource in that decisions leading to increased or decreased risk will generally increase or decrease other resources.) Critical resources also include operational timeline and relationships (teaming). Timeline here differs from development schedule although considerations of adequate timeline for post-launch activities have design and implementation trade-space implications. Team building includes many items, such as establishing efficient communication paths and lines of authority, matching skills to tasks, and delegating appropriately. A common understanding and commitment to the goals of the mission, a shared understanding of priorities, and a basis of trust are hugely valuable resources.

The techniques successfully applied on Viking stand as a model for application to smaller science-space projects, and the lessons learned can be applied to future space-science programs. Cassinis challenge of how to handle resource margins for payload instruments resulted in the creation of the Resources Trading System (RTS), a creative solution to a common problem.

The Cassini payload manager allocated payload resources (e.g., space, weight, power), and margin comprised dollars by fiscal year, mass, power, and data rate. An exchange was set up to facilitate trading margin among the instruments and also with the spacecraft. If instrument A had excess mass, the PI could place a sell offer on the exchange, stating the amount of mass and the price (e.g., $, W, bps). If instrument B was short of mass and its PI liked the price, he could buy. The payload manager then recorded the trade, and the official allocations to A and B were changed accordingly. This was a winwin situation as each party felt they had improved their balance of resources.

Proper attention to margins is a key aspect of establishing a strong foundation for program execution, and it goes beyond technical margins to include schedule, cost, and timeline margins. Understanding the application of heritage for missions is also key to avoiding surprises that may erode project margins.

Abstract

Throughout NASAs history, international collaboration has played an important role in both its science and human spaceflight programs. This collaboration has become the new norm in space, as more than sixty international space agencies increasingly work together in a broad range of space-related activities. Nearly two-thirds of NASAs space-science missions now involve international collaboration on many levels. Increased international collaboration in space is expected to continue in coming years and is well aligned with administration space policy. Tightening budget constraints are increasing the importance of collaboration even as they introduce new challenges. This session will consider these trends and how they affect project management.

Our international partners have diverse national goals in space as well as different general governance and space agency structures and processes. In addition, language barriers and variations in cultural norms and practices add to the interest but also to the challenges of implementing space projects with foreign partners. Awareness and adaptation to these differences are an important key to success.

Ensuring NASA compliance with U.S. export control laws and regulations while accomplishing NASA missions internationally is also a challenge. Understanding the requirements under international cooperative agreements and the transfers required under those agreements is key for a successful export-compliance effort. We want to maximize the benefits of our international efforts while ensuring that we comply with U.S. export control laws and regulations.

Lessons Learned from Prior Missions

Speakers

  • John (Tim) Schofield is a principal scientist at the Jet Propulsion Laboratory ( JPL) and the principal investigator for the ExoMars climate sounder investigation selected for the NASA/European Space Agency 2016 ExoMars Trace Gas Orbiter mission. He is also deputy principal investigator for the Mars Climate Sounder (MCS) instrument now in its fifth year of returning Mars atmospheric data from the Mars Reconnaissance Orbiterand is a coinvestigator on the Diviner Lunar Radiometer Experiment, now in its second year of returning lunar-surface data from the Lunar Reconnaissance Orbiter.
  • Andrew Cheng is the chief scientist for the Space Department at the Johns Hopkins University Applied Physics Laboratory. He now serves as the departments external liaison for space science and will provide independent science advice and strategic vision to lab and department leadership. Dr. Cheng brings considerable experience to the position, having been an interdisciplinary scientist on the Galileo mission to Jupiter, a co-investigator on the Cassini mission to Saturn, and a scientist on the Japanese-led MUSES-C asteroid mission. He was project scientist for the historic Near-Earth Asteroid Rendezvous mission, which was the first to orbit (and eventually land on) an asteroid. He is a member of the Mercury Surface, Space Environment, Geochemistry, and Ranging mission team and principal investigator for the long-range reconnaissance imager instrument on the New Horizons mission to Pluto and the Kuiper Belt. He recently completed a one-year assignment at NASA Headquarters, serving as deputy chief scientist for Space Science in NASAs Science Mission Directorate.
  • Steve Jolly is the Lockheed Martin systems engineering director for the GOES-R program (next-generation weather satellites in geosynchronous orbit) in the sensors and exploration systems line of business. He is also the program manager for the Mars Reconnaissance Orbiter and was chief engineer during its development. Dr. Jolly has served project Orion off and on as an independent advisor and tiger-team lead for entry, descent, and landing (EDL), and previously served as a member of EDL systems engineering team and critical events risk process for Phoenix, Stardust, and Genesis. He was also program manager for the Mars Science Lab (MSL) aeroshell and is a member of the Independent Assessment Panel for the MSL landing-site selection. He was chief systems engineer for Mars Sample Return. For the ill-fated duo, Mars Climate Orbiter (MCO) and Mars Polar Lander (MPL), he was flight systems design lead (MCO) and flight operations lead (MCO and MPL).

NEAR

Using six highly specialized instruments to gather data about its primary target, asteroid 433 Eros, the Near Earth Asteroid Rendezvous (NEAR) mission was designed to answer many fundamental questions about the nature and origin of asteroids and comets. It was the first of NASAs Discovery missions and the first mission ever to go into orbit around an asteroid. The ultimate goal of the mission was to rendezvous with and achieve orbit around Eros in January 1999 and study the asteroid for approximately one year. A problem caused an abort of the first encounter burn and the mission had to be rescoped for a December 1998 flyby of Eros and a later encounter and orbit on February 14, 2000. Prior to its encounter with Eros, NEAR flew within 1,200 km of the C-class asteroid 253 Mathilde in June 1997.

The NEAR mission is remembered as the first to orbit an asteroid successfully and also to land on one successfully, but those of us who lived NEAR (we did not just work on NEAR) remember it as both the best of times and the worst of times. Andrew Cheng will share recollections of the good and the bad, which have the common theme that the unexpected always happens.

Managing Software Development The Hidden Risk

There is not a major space system that has not experienced serious software development challenges, especially true of real-time, embedded software for spacecraft. But what is at the root cause? Are flight-software-development processes inadequate? Are spacecraft more functionally complex than in the past, resulting in these challenges? Why cant the software subsystem meet cost and schedule?

Is systems engineering broken? This talk will address these questions head-on and explore the shocking truth of what modern space exploration, and more specifically spacecraft development, has become. A revolution has taken place and is accelerating. Ignore it and an enormous price will be paid. And the implications on safety and mission success are staggering indeed. A major transformation of how we develop these SOS must begin immediately.

Previously she led the technical, management, and cost evaluation (TMC) for the Science Mission Directorate (SMD) Phase A studies for New Frontiers, Discovery, and Explorer. She also led the TMC evaluations for SMD instrument announcements of opportunity for Solar Probe Plus, the Focused Opportunity for Solar Orbiter, Solar Dynamics Observatory, Solar TErrestrial RElation Observatory, and Magnetospheric Multiscale.

Abstract

To encourage the submission of the highest-quality mission proposals and concept-study reports, the Science Office for Mission Assessments maintains an ongoing effort to identify and analyze common areas of major weakness resulting from the technical, management, and cost-review process. The results of this effort will be described, including appropriate lessons learned that can provide valuable guidance to future mission proposal and concept-study teams. Additionally, the cost and schedule performance of a set of Science Mission Directorate missions will be discussed to provide further insight into the challenges that can arise for missions in the detailed development and implementation phases.
