Cybera provides overall project management
CI projects in Space Science…
Project Involvement Institutions involved in the CSSDP/CESWP projects CANARIE (Network Enabled Platform) Cybera (Project Lead) CSA (CGSM and e-‐POP) Universities -‐ Alberta, Calgary, Saskatchewan, New Brunswick, Michigan, UCLA, Colorado, Augsburg College, Peking
Missions – NASA THEMIS, CSA e-‐POP, CSA ORBITALS
Defini7on… A Virtual Observatory (VO) encompasses all forms of
network tools, databases and websites that are utilized for collaborative research. From Oct. 2010 NSF will require data management
plans as part of all NSF funding proposals. “This addresses the need for data from publicly-funded
research to be made public” (NSF Deputy Director)
Technical innovation means increasingly sophisticated instruments are being proposed and deployed Data volumes are growing exponentially Future experiments are expected to generate upwards of 1015 Bytes
of data !
Data management challenges are numerous Data is stored in different formats across heterogeneous
computer environments Standards where they exist are still rapidly evolving Appropriately defined meta-‐data is needed to find and access
relevant “physical” data (e.g., SPASE) Collaboration is key to making advances in space science
Space Data challenges…
CSSDP is… A “one-‐stop-‐shop” to discover, gather and visualize relevant data (using CANARIE’s high-‐speed network)
A gateway to make data available to other researchers An environment to host common analysis tools A place to collaborate with research teams A workflow engine to simplify research tasks www.cssdp.ca
Metadata… Metadata
Description of data sets or other resources Allows catalogue and search of data CSSDP follows NASA/SPASE XML standard Usually generated from data file path/name
Metadata includes Date/Time Project, Instrument, Observatory Data Stream
SPASE XML -‐ resource then can be shared over internet

Who uses CSSDP? Data Providers
Make data available to others to use and study Researchers
Discover, view, download and analyse data from multiple sources
Collaborators Teams who want to collaborate online in a common, data-‐integrated environment
Researchers One-‐stop shop to discover and download data from multiple sources
Data availability reports Quick-‐looks and online parameterized plots Annotate data Automate repetitive tasks – workflows Access data directly from desktop analytics
Integration with IDL tools Web services
Data Providers Make data available when you want, how you want Control data access Track usage Determine how you want your data presented Provide quick-‐looks and user-‐defined graphics On-‐demand plots Share other analytic tools
Collaborators… CSSDP features an integrated collaboration environment
Workspaces -‐ notices, calendars, discussion boards, upload documents, version control
Public workspaces -‐ project notices, RSS feeds Private workspaces -‐ sharable, team collaboration Data integration (planned enhancements)
Sputnik 1 – October 4 1957 to January 4th 1958 No instruments Caught everyone by surprise
The “space race” was on – battle of political ideologies
Where are we going?…
Sputnik 2 – November 3rd 1957 to April 14th 1958 Many scientific instruments Carried Laika Thermal insulation failed; Laika died after a few hours
Satellite was enormous and easy to track
(the space age)
Explorer 1 – January 31st 1958 to March 19th 1970 Several science instruments Discovered the radiation belts (confirmed by Explorer 3)
Established that micrometeorites were not a threat at LEO: 100km-‐1000km, e.g., Space Shuttle
William Pickering, James Van Allen, and Wernher von Braun
(the space age)
Yuri Gagarin (1934-‐1968): April 12th 1961 – first human to orbit Earth
John Glen (1921-‐): February 20th 1962 – first American to orbit Earth (3 times)
Neil Armstrong (1930-‐): July 21st 1969 – first human to walk on the Moon
(the space age)
Living With a Star (LWS) Understanding the effects of the
Sun on Earth and the solar system The Sun is coupled to planetary
systems and space through: -‐ Radiation -‐ Charged particles -‐ Electric and Magnetic Fields
The Plasma Universe 99 % of visible matter in the
universe is in plasma state
Plasma: an ionized gas of equal densities of ions and electrons
Living With a Star…
Living With a Star…
Solar-‐Wind-‐Magnetosphere-‐Ionosphere-‐Coupling drives ‘Space Weather’
SW affects space and ground based assets in numerous ways
Who Cares?…
Geostationary satellites are affected by Space Weather Surface charging by keV electrons
Internal charging by relativistic “killer” electrons >2MeV energy
Solar flare protons cause phantom commands
Satellite damage…
Old View: STATIC New View: DYNAMIC
Radia7on Belt Storm Probes... RBSP– 2 spacecraI to understand rela7vis7c par7cle accelera7on, transport, and loss. Implemented as the 2nd mission in Living with a Star.
Launch 2012 Perigee: ~700 km altitude Apogee ~5.5 Re geocentric altitude Inclination ~10 degrees Sun pointing, spin stabilized Duration 2 years (expendables 4 years)
UofA ORBITALS Satellite...
Canada’s contribution to LWS and NASA’s RBSP Mission
• Planned launch 2011-‐12. Examine wave-‐par7cle interac7ons in Van Allen Radia7on Belts (cf. NASA RBSP)
• Partnered with NASA “MORE”; will contribute spacecraI instruments
• 12 hour orbit with very long-‐las7ng CGSM-‐ground-‐ and GEO conjunc7ons.
CESWP is… An environment to share, run and collaborate on simulation and analysis work Involves the creation of a Compute Cloud that spans Canada and several countries
Involves moving computer models into the cloud, and making them available
Not intended to replace entities such as WestGrid www.ceswp.ca
Integra7on of data and models...
Simulations using the Space Weather Modeling Framework – SWMF
Polar satellite observations of the Auroral Oval in UVI – the poleward boundary is called the OCFLB

CSSDP does the rest... CSSDP nightly processes will automatically run and catalogue your data (consume SPASE metadata)
As new data appears on your site CSSDP will automatically generate new SPASE XML metadata and register it
New data streams can be added any time
