the dream of yesterday is the hope of today and
the reality of tomorrow.

Vision Mission
  • The Systems Engineering and Advanced Concepts
    Division (SEACD) provides end-to end systems
    engineering for programs, missions and projects
    including innovative concepts, system
    architectures and systems for new missions,
    technologies and concepts. The Division develops
    implementation and risk mitigation strategies for
    the infusion of technologies, ensuring that
    systems technology advancements are carried from
    concept through final design. The Division
    performs technical systems engineering and
    tradeoffs across the full life cycle for NASA
    Enterprise and external customers. The missions
    include Space and Earth science as well as
    enabling technologies.

Creating a Core Systems Engineering Capability
  • Why a Core Systems Engineering Capability?
  • Provide improved systems engineering capability
    to the projects without just adding more systems
    engineers to the projects or requiring the
    projects to go to more support contractors for
    systems engineering.
  • Provide capability to address the new systems
    engineering requirements without increasing
    systems engineering assignments.
  • Assignment of a few civil servants and some
    support contractors to the core, if properly
    used, would preclude a larger number of systems
    engineers being added to the projects staffs.
  • For maximum productivity, the latest tools must
    be available and utilized.

21
Creating a Core Systems Engineering Capability
  • The Systems Engineering Core
  • A small group of engineers who are experts in the
    systems engineering process, as well as those in
    training.
  • The nucleus of this group is comprised of civil
    servants who are supported by a larger number of
    support service contractors.
  • The core group supplies systems engineering
    expertise to all the programs and projects across
    the center and serves as a resource to all the
    collocated systems engineers.
  • Systems engineers are rotated through this core
    group as they come off of projects.
  • The core group acts as mentors to junior systems
    engineers in the SEED program and elsewhere.
  • A small number of civil servants are required for
    continuity of policy and to maintain systems
    engineering as a GSFC core competency.

System Engineering Education Development (SEED)
  • A cooperative effort of STAAC and AETD to develop
    promising discipline engineers and junior systems
    engineers into end-to-end mission systems
    engineers or instrument systems engineers.
  • Targeted at shortening the development cycle to
    under three years.
  • Focuses development through a curriculum of
    well-defined course work (defined through the
    DACUM process), rotational assignments through
    all phases of the NASA life cycle and mentorship
    from senior systems engineers.
  • The pilot program was initiated last year.
  • The participants have provided very positive
    feedback regarding rotations, courses and
    mentors.
  • Anticipate roll-out of the competitive
    announcement from OHR this Fall.

Image a Black Hole!
  • Direct image of a black hole event horizon
  • - Fundamental importance to physics
  • - Captures the imagination

Close to the event horizon the peak energy is
emitted in X-rays
31
Looking Behind the Microwave Background
The universe is totally transparent to
gravitational radiation, right back to the
beginning of time and opens a new window to view
behind the microwave background.
In the nearer term. Polarization of the
microwave background contains the signature of
gravitational waves from the period of inflation
Future vision mission CMBPOL mission will
detect it
A mission to follow LISA will search for this
background radiation
