I. What is Space Science?
• Science of solar
system phenomena
and objects.
• Science of space &
science from space
• “Everything above the tropopause”.
What is Space Science?
Space Science includes:
• space physics and
space weather
• planetary geology
• remote sensing of
Earth … from orbit
• astrobiology
• space technology
Astronomy  extra-solar system,
Earth Sciences  surface and below.
II. Intentions for the Decadal Plan
• Build a sustainable world-class community of Australian
space scientists.
• Present exciting, widely-agreed, visionary research
themes and projects directed towards longterm scientific
goals of the Australian space science community.
• Link the research and goals with the interests and
requirements of Australian constituencies: Government,
Industry, wider scientific community, and public.
• Develop and optimize the space science community for
the nation’s benefit.
• Be the official position of the space science community
and Academy on major science and funding projects.
• Lead to increased Government funding of space science.

• Steering Committee: final responsibility for the development, writing, approval,
and publication of the Decadal Plan.
• Working Group: researches a specific component of the Decadal Plan and then
provides recommendations.
• Now writing Draft Plan & refining inputs (mid 2007 release).

IV. Global Science Themes (draft)
(i)
Sun and Space to Earth (SSE)
Understand how activity on the Sun and in space develops throughout the solar
system and affects humans and human technology.
(ii)
Plasma to Planets (P2P)
Understand evolution from plasma & dust to the present-day Sun, Earth, and
other solar system bodies and then beyond.
(iii)
(OAEPS)
Observing Australia, Earth and Planets from Space
Remotely sense and model the atmosphere, climate, oceans, surface, life, and
geology of Australia, Earth and other planets and solar system bodies.
(iv)
Life and Technology in Space (LIFTS)
Understand the effects of space’s harsh environment on life and technology,
develop space technology, and consider how life evolved on Earth and perhaps
elsewhere?
V. Taste of Science & Projects (Draft)
• Foci: (i) our strengths & (ii) interests of
Government / industry.
• Coordination Center / Corp.
•
•
•
•
•
1 Grand Challenge project (Sundiver)
2-3 Flagship projects (e.g., Lightning, Octant)
Smaller projects (Digi-radar, balloons, nanosats)
Education & Training
Collaboration on international projects
Flagship: “Octant” (Themes SSE,
P2P, & LIFTS.)
• To study Sun-Earth connections & space weather from Sun to
magnetosphere to ionosphere/ground on a global basis (pole ↔ equator).
• To measure and model (equator to pole) the dynamics, and coupling of
the atmosphere, ionosphere, & magnetosphere over Australian region.

• Instrument ~1/8 World’s surface: Radar, optical/IR, GPS TEC & scints,
magnetometer, digisonde, solar radio, and radio comms.
• Connection to FedSat and international space/ground networks
• Provide vital ionospheric info for SKA, NTD, MWA etc. (justify in Oz).
• Provide ionospheric, atmospheric, and comms info (and cover) ….
Lightning-1 & -2: Flagship Concept
L2
L1
• 1 equatorial,
• 1 highly inclined.
• 250-1000 km altitude
(alterable)
• Upgradable
• Dynamics of equatorial to highlatitude ionosphere & atmosphere
• Lightning, sprites & global
electrodynamic circuit.
• Greenhouse gases & climate
change, local and large-scale –
measurement & verification.
• Remote sensing Australia
• Gravimetric & magnetic maps of
Australia (geodesy, minerals..)
• Demonstrate Australian
technologies (electric propulsion,
spacecraft/comms, instruments)
• Beacon/Rec for ionospheric radars
Grand Challenge: Sundiver (All themes)
OVERVIEW
Objectives:
• World first: in situ investigation of the
coronal and inner solar wind plasma via
infalling spacecraft.
• First Australian investigation of a
planet’s surface and atmosphere via a
close gravity-assist flyby. (Moon, Venus
Mercury, asteroids, comets etc.)
• Use ANU space propulsion system.
Applications:
•
•
Graphite Sun shield?
Discover corona’s heating mechanism. Design – simplified by certain death.
Planetary geology (grav/mag) + atmos •Redundancy: 2 spacecraft at once?
MISSION / INSTRUMENTS
•Magnetometer, plasma waves.plasma &
neutral measurements.
• Imaging & spectrometers.
• Propulsion : major orbit changes
RESOURCES TBD
Time Line: 5-10 years?
Collaboration: As required. .
VI. Overview
•
•
•
•
•
NCSS & the Steering Committee are developing
the first Australian Decadal Plan for Space
Science: 2007-2016,
www.physics.usyd.edu.au/~ncss .
Plan launch expected in second half of 2007.
Exciting world-class science and technology that
is interdisciplinary, involves the enabling
sciences, & has many applications with vital
national benefit.
Major training and education components.
Strong international links.
