Canadian Report to ILWS WG

William Liu

Space Science Branch, Canadian Space Agency


Opening remarks l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
The Ground-Based Program

  • CGSM

  • THEMIS GBO

  • AMISR


Canadian geospace monitoring l.jpg
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 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 l.jpg
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 l.jpg
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 l.jpg
Intermission Science

  • Ground and space observations nail down the onset wave mode


The space component l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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
