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
