Sun-Earth Connection 2003 Roadmap
the Sun, Heliosphere and Planetary Environments as a Single Connected
Life on Earth prospers
in a biosphere that is sustained by energy from the Sun.
The Earth’s upper atmosphere and magnetic field generally
protect the biosphere against the more dangerous electromagnetic
radiation and particles emanating from the Sun. In turn, the extended magnetic field of the Sun shields the
Earth from very high-energy radiation that originates at supernovae
and other cataclysmic events outside the solar system. Within
NASA's Office of Space Science,
the Sun-Earth Connection (SEC) Division's primary goal is to Understand
the Sun, heliosphere, and planetary environments as a single connected
Roadmap outlines the future of the SEC Division. Science
objectives are presented and prioritized and the programs and missions
necessary to address these objectives are identified.
To accomplish its overarching
goal, the SEC Division investigates the physics of the Sun, the
heliosphere, the local interstellar medium, and all planetary environments
within the heliosphere. Taken
together, these studies encompass the scientific disciplines of
solar physics, heliospheric physics, magnetospheric physics, and
aeronomy. They address
problems such as solar variability, the responses of the planets
to such variability, and the interaction of the heliosphere with
Recent years have witnessed
the growing importance of SEC investigations focused upon space
weather, the diverse array of dynamic and interconnected phenomena
that affect both life and society.
Space weather effects disturb radio and radar propagation
through the ionosphere, damage objects or astronauts outside the
Earth’s atmosphere, substantially modify the ozone layer, and may
induce some climate shifts. Understanding space weather effects becomes more important
as the government and private sectors rely increasingly on space-
and ground-based assets subject to the influences of the space environment.
Connection 2003 Roadmap
the Sun, Heliosphere and Planetary Environments as a Single
Sun-Earth Connection (SEC) Division has formed a Roadmap Committee
that will update the SEC Strategic Plan for 2003-2028 with the participation
of the SEC community as an input to the OSS Strategic Plan.
current members of the Roadmap team are: Stephen Fuselier (chair),
Thomas Duvall (co-chair), Brian Anderson, Ed DeLuca, Don Hassler,
Mike Hesse, Roberta Johnson, Randy Jokipii, Janet Kozyra, Bill Kurth,
Craig Pollock, Ray Roble, Ed Roelof, Karl Schreiver, Nathan Schwadron,
Harlan Spence, Steve Suess, Gary Swenson, Roy Torbert, Tim Van Sant,
The SEC Division's primary goal is to:
Understand the Sun, heliosphere, and planetary environments as
a single connected system.
three primary science objectives are to:
- Understand the changing flow of
energy and matter throughout the Sun, heliosphere, and planetary
- Explore the fundamental physical
processes of space plasma systems.
- Define the origins and societal
impacts of variability in the Sun-Earth connection.
