Canadian Report to ILWS WG

William Liu

Space Science Branch, Canadian Space Agency

opening remarks
Opening Remarks
  • Canada has benefited significantly from ILWS
  • The Canadian community and CSA have established a strong foundation for the program with a healthy mixture of ground-based and space-borne missions for the next 5 years
  • We are looking ahead for the next 10
the canadian st program
The Canadian ST Program
  • Landmass and history have made ground-based auroral and geomagnetic observations a centerpiece of our program
    • CSA has made a long-term commitment to support this element
    • It is a no-brainer
    • It is cost-effective
    • It is hugely productive
      • Hundreds of papers
      • Dozens of highly qualified people in career positions
      • Media coverage and public interest
the canadian st program4
The Canadian ST Program
  • The CSA is aggressively purusing opportunities for space-borne missions in order to maximize the science that can be done
    • ePOP
    • SWARM
    • ORBITALS
    • Kuafu
    • PCW mission
    • SCOPE/Cross Scale
the ground based program
The Ground-Based Program
  • CGSM
  • THEMIS GBO
  • AMISR
canadian geospace monitoring
Canadian Geospace Monitoring
  • The CSA concluded a successful AO last year for the next 5 years of CGSM
  • Selected projects are:
    • Fluxgate magnetometer array (CARISMA-A) for studies of global-scale current flow
    • Induction coil magnetometer array (CARISMA-B) for studies of VLF waves implicated, for example, in the acceleration of killer electrons
    • A multispectral auroral all-sky auroral imager array for substorm and related studies
    • A meridianal scanning photometer array for detailed characterization of precipitating particles
canadian geospace monitoring7
Canadian Geospace Monitoring
  • Selected projects (continued)
    • An arctic ionosonde/GPS/photometer array to characterize polar cap convection, transpolar ionospheric condition, and their effect on auroral activities
    • Support of the operation of Canadian SuperDARN (4 radars now, with PolarDARN providing complete northern polar cap coverage)
    • A data analysis and modeling module to tackle scientific questions behind the CSGM data
  • Also, the CSA is negotiating with its government partners on
    • Continuing Canada’s successful program in space weather forecasting and effect mitigation and management
themis gbo
THEMIS GBO
  • The CSA will continue to support GBO operation pursuant to NASA’s extension of the THEMIS mission
  • Canadian contributions are managed through two contracts
    • ASI operation (University of Calgary)
    • GMAG operation (University of Alberta)
amisr
AMISR
  • Canada has been interested in AMISR from early on as a major space science facility on Canadian soil
  • A ‘chancy meeting’ last October led to the opportunity for Canada to contribute one of the two Resolute AMISR faces at ~$15 M
  • Eric Donovan and Jean-Pierre St-Maurice have secured the necessary university allocation to make a bid to Canada Foundation for Innovation funding (a formality in most cases)
  • Resolute AMISR, starting operation in ~2010, will be the most advanced instrument to study the polar ionosphere and its connection to auroral ionosphere.
intermission science
Intermission Science
  • Ground and space observations nail down the onset wave mode
the space component
The Space Component
  • The CSA has pursued a balanced approach in shaping our program. A space component is essential
  • Our space component is geospace-centric
    • Further, it has a strong IT flavor
  • However, we are venturing out to the magnetosphere and radiation belts
  • The following describes some ongoing projects
slide16
ePOP
  • To be launched in the second half of 2009
  • Up to 2-year mission in an elliptical 300  1500 km, 70º orbit to study
    • Acceleration of ion outflow
      • O+ ions are a major factor in storms
    • Thermal and secondary auroral electrons (up to 100 eV)
    • Fast, DMSP-type, auroral imaging in IR/VIS
    • Radio tomagraphy of the ionosphere with radio receiver, SuperDARN, beacon, and GPS occulation
  • ePOP and C/NOFS form a nice high and low-latitude combo
  • Launch delay fortuitous push the mission to potentially overlap SWARM
    • Elliptical and circular orbit complementarity, as well as instrument synergy
swarm
SWARM
  • Three-satellite ESA mission to study geomagnetic field, 2010-2014
    • Canada to build the electric field instrument (CEFI)
  • E-field measurement to remove geospace "noise"
  • Combined E and B instruments can measure the Poynting flux to W/m2 accuracy
  • Constellation plus precision will allow field-aligned current dynamics to be probed in greater detail
  • In conjunction with contempraneous magnetospheric missions, will open new doors on MI coupling research
orbitals
ORBITALS
  • The CSA is finishing Phase A
  • A SRR will be conducted next month
  • A presentation to CSA Executive is planned in late summer for decision on the project
  • Continue to work with NASA on ways of cooperation
  • Time is pressing for the upcoming solar max
kuafu
Kuafu
  • The Chinese space science community gave its seal of approval last June
  • The comprehensive review report accepted by CNSA
  • CNSA changed the terms of cooperation
    • International contributions of bus and launchers solicited
  • Situations in Europe also dicy
  • Scenarios of decoupling Kuafu A and Kuafu B discussed, but only sporadically
  • The September Kuafu meeting in Kunming will tell whether we have a mission or not, and if yes, what it is like
slide20
PCW
  • Polar Communications and Weather Satellites is a mission concept study at the CSA – it consists of a pair of Molnya satellites
  • Auroral imager is a ‘tertiary’ science payload (but increasing in importance)
scope cross scale
SCOPE/Cross Scale
  • Canadian interest early on during Cross Scale proposal stage (University of Alberta part of the magnetometer team and will have CSA support to explore Canadian contribution to this element)
  • Interest heightened during my sabbatical at Imperial and almost daily lunch meeting with Steve Schwartz
  • The best way for Canada to make a contribution is through SCOPE, due to its spare launch capability
  • Discussion started
    • Optimistic that something will happen soon.
concluding remarks
Concluding Remarks
  • Canada’s ST program is in good shape
  • There are some long-term concerns
    • Human resource is a greater worry than financial resource for Canada
  • The CSA is working with Canadian universities to explore a partnership through which a national institute for space science can be formed through joint Federal and Provincial funding, so that
    • Advanced instrument development can be conducted independent of missions
    • HQP can be trained in a cutting-edge and challenging environment
    • Promising scientists and engineers can be retained
    • Stay tuned
