5Vision 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.

20Creating 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.
21Creating 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.

23System 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.

- 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
31Looking 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
