As many readers will have heard at CASCA 2018, the MSE collaboration continues its work towards preliminary design starting in 2019. The MSE Management Group has added two institutions from the United States as observers: Texas A&M University and the National Center for Optical-Infrared Astronomy (NCOA). Including recent discussions with Texas A&M, the partnership has identified about half the resources (cash and in-kind contributions) needed for preliminary design, and are discussing possible contributions from NCOA beginning in 2019. The partnership will continue to identify and secure resources while preliminary design activities get underway.

The preliminary design phase will be governed by a Statement of Understanding (SOU) to be signed by the current MSE participants – Canada, France, Hawaii, China, Australia, and India – and endorsed by future participants when they join the project. The MSE SOU specifies the (non-binding) contributions that Canada anticipates providing during preliminary design, and the framework within which participant contributions will be converted into a "Beneficial Interest" in MSE.

As was the case in the early days of the Thirty Meter Telescope (TMT) partnership, the Association of Canadian Universities for Research in Astronomy (ACURA) has been approached to be the Canadian signatory to the MSE SOU. The ACURA Board is considering this request in recognition of MSE's strong support in the 2010 Long Range Plan and 2016 Mid-Term Review, and the significant role Canadians have played to date in developing the Detailed Science Case. Without a signatory to the MSE SOU, Canada will be downgraded to Observer status and lose voting rights on the MSE Management Group. If you support Canadian involvement in MSE during the preliminary design phase leading up to the next Long Range Plan, contact your institution's ACURA representative and let them know. A slightly dated list of representatives can be found here.

Preparation for CFI Proposal

Ultimately, maintaining a role in MSE will require that Canada make further cash and/or in-kind contributions to the preliminary design phase within the next few years. To support this aim, we are engaged in planning for a CFI proposal submission for the next round (anticipated in 2019). If you are interested in contributing to this effort, the relevant points of contact are Colin Bradley (Victoria Engineering Professor and CFI Project Manager for MSE; Enclosure), Michael Balogh (Waterloo; Low/Medium Resolution Spectrographs), Sarah Gallagher (Western; Software), and Kim Venn (Victoria; Fiber Transport System). Additional industrial partners to support these design components are also needed; sharing your connections would be greatly appreciated. The points of contact can also help develop promising leads for industrial partners.

Status of Science Team Membership

In response to the call for new science team members, the MSE Science Team now has 203 participants, including 31 Canadians from 15 institutions in six provinces. The Project Office is currently organizing team members into Science Working Groups in preparation for Design Reference Survey work that will begin within the next couple of months. If you signed up for the Science Team but have not been receiving e-mails, please contact MSE Project Scientist Alan McConnachie.

MSE Project Scientist Search

After successfully shepherding MSE through the conceptual design process, Alan McConnachie will be stepping down as Project Scientist at the end of 2018, though he will continue his involvement with the Science Team. The Canadian MSE team would like to thank Alan for his excellent leadership during his tenure as Project Scientist. He deserves significant credit for bringing the project to the stage where the external reviewers were “very impressed by the level of sophistication that the MSE project team has brought to this project”. A search for a new Project Scientist is underway.

Victoria was the venue of this year’s annual general meeting of the Canadian Astronomical Society (CASCA). CASCA 2018 was co-hosted by the NRC-Herzberg Astronomy & Astrophysics (HAA) and the Dept. of Physics & Astronomy at UVic, with substantial volunteer help from members of the Royal Astronomical Society, Victoria Chapter, and the Friends of the DAO. The meeting ran from 22-26 May at the Victoria Conference Centre, situated in the heart of this scenic city. Victoria was chosen to host the conference this year to coincide with the 100th anniversary of the 1.8m Plaskett Telescope at the Dominion Astrophysical Observatory (DAO) in Victoria. This article summarizes highlights from the various science and centennial sessions, as well as the special events hosted during the conference.

With well over 300 registered participants, this year’s meeting ranked as one of the bigger CASCA meetings on record. The meeting kicked off to a great start with a vibrant graduate students workshop, which included a hands-on exercise on the Gemini Observatory’s Fast Turnaround Program, and an introduction to the high performance computing (HPC) resources for research offered through West Grid/Compute Canada. The afternoon session focussed on networking with industrial partners through a “pechakucha” and rapid fire presentations by the representatives of the industries. The workshop ended with a wine and cheese mixer for the graduates students and the industrial reps, which was then followed by the conference welcome reception for all attendees.

The first day’s proceedings of CASCA 2018 got underway on Wednesday with an eloquent welcome to the Songhees and Esquimalt First Nations territory by Tsawout Elder Victor Underwood. Following this territorial welcome, and in a reciprocal gesture of respect and recognition, astronomer Dave Balam (DAO) presented a plaque to Chief Harvey Underwood of the Tsawaout First Nation (TFN) to commemorate the naming of asteroid 402920 as Asteroid Tsawout (see related Globe and Mail article). Dave named this asteroid that he had discovered in 2007 for the TFN, one of the five bands which constitute the Saanich Nation in the Coast Salish lands. The Plaskett Telescope on Observatory Hill sits on the territorial lands of the Tsawout First Nations and was their winter camp, says Dave. This is the reason he has chosen to name the asteroid for the TFN. The plenary session continued with opening remarks by UVic President Dr. Jamie Cassels and NRC/HAA General Manager, Dr. Greg Fahlman, followed by two very interesting centennial talks. First, Peter Broughton (author of “John Stanley Plaskett – a northern star”) offered a biography of John S. Plaskett after whom the 100 year-old telescope in named. Dennis Crabtree then gave a fitting summary of the many major achievements of the Canadian astronomical community over the past century.

The fully packed conference schedule shows the diversity and depth of the centennial and science sessions, which followed over the next four days of the conference. The more detailed conference program with the titles, authors and abstracts of all the centennial and science sessions has also been posted on the CASCA2018 website, which will remain live for the next year (till May 2019). The centennial sessions were offered as plenary sessions while the science sessions ran as concurrent two and at times three parallel sessions. The over subscription rate for contributed talks was a remarkable 3-to-1 in this conference. It is to the credit of the Science Organizing Committee for having allocated the talks well taking into account gender balance, geographical distribution and other diversity and inclusivity policies adopted by CASCA. In addition to these science sessions, teachers workshops (both elementary and secondary schools) were also organized and very successfully run by Julie Bolduc-Duval (Discover the Universe) and Mary Beth Laychak (CFHT) with assistance from other members of the CASCA Education and Public Outreach committee. Of special note was a presentation on the traditional knowledge of the First Peoples regarding the thirteen phases of the Moon given by Dr. Nick Claxton, an indigenous educator from the UVic education department.

Related to education and public outreach (EPO), we were fortunate to have had a moving yet very powerful message from Elder Dr. Barney Williams of the Tla-o-qui-aht First Nation on the role of education in reconciliation. As a survivor of the residential school system, he was eminently suited to eloquently warn us of the dangers of racial superiority, and to turn the horrors of his own childhood experiences into a message of hope toward reconciliation and mutual respect amongst all peoples based on education.

Several special events were offered during the course of the conference. On the first day, Bob McDonald (CBC Radio, Quirks and Quarks) gave an excellent and well attended public lecture, intriguingly titled “What if everything you know is wrong?”. The conference banquet marked the end of the second day. Held at the Royal BC Museum, the atypical banquet was set up as a series of food stations featuring various cuisines distributed throughout the permanent exhibits of the First Nations and the city of Victoria. Judging by the feedback from participants later, the intention to encourage the conference participants to walk around and mingle during the banquet worked well. On Friday evening, the DAO centennial celebration was held with a special cake (shaped expertly as the Plaskett observatory), dome tours, public lectures and an open house of the Centre of the Universe. The skies too cooperated well and the 200+ attendees were able to enjoy viewing Venus and Jupiter through the RASC 16″ telescope.

The meeting was a huge success judging by the verbal feedback of many participants. Our sincere thanks go to all members of the LOC and to many volunteers for their contributions and to all our sponsors (shown on the CASCA 2018 website) for their generous financial support. We now look forward to the next annual general meeting hosted by McGill University in Montreal June 17 – 20, 2019.

SPICA Update

SPICA Satellite

SPICA Satellite


On 7 th May 2018, SPICA was selected by the European Space Agency (ESA) as one of three candidate missions to be studied in parallel over the next three years in preparation for a final 2021 down-select for ESA’s fifth medium class mission in its Cosmic Vision science programme. If successful in the 2021 down-select, SPICA would be built to launch around 2030. SPICA is a joint European-Japanese project that offers significant gains in far-infrared spectroscopic and survey capabilities. Detailed information about SPICA and its three instruments can be found here and here.

Canada was a founding member of the SPICA/SAFARI consortium and through its contributions over the last decade is now positioned to build the mission critical high resolution polarizing Fourier transform spectrometer (Martin-Puplett Interferometer – MPI) for the SAFARI instrument. This MPI builds on Canada’s contribution to the Herschel/SPIRE instrument and was recognized by the SAFARI consortium as an area of excellence both in Canadian academia and industry. The return from this investment to the Canadian astronomical community will be several times more than that awarded to the Canadian Herschel/SPIRE team. Herschel was, of course, an amazing success, in part due to the significant contributions from the Canadian scientists involved. Indeed, the recent success of SPICA is regarded by many as a direct result of the success of Herschel.

As stated in the SPICA Press Release that accompanied its ESA selection:

“The promise of SPICA is made possible by the combination of a number of significant innovations. A key component is the use of a large 2.5 metre diameter telescope that is cooled to almost 270 degrees below zero, to reduce the background radiation emitted by the telescope itself to the absolute minimum. With such a low background the extremely sensitive Transition Edge Sensors (TES), developed both in the Netherlands at SRON as well as in partner institutes in the UK and the US, can be used to their full potential. The combination of the cold telescope and the ultrasensitive detectors will make SPICA the most sensitive observatory in the mid- and far-infrared ever – with this extreme sensitivity the SPICA instruments will be able to take the spectral fingerprints of objects out to the farthest reaches of the universe.

The observatory will have three instruments covering the full mid- and far-infrared, the wavelength domain between 12 and 350 microns. A combined mid-infrared camera and spectrometer will be provided by a large Japanese consortium led by the University of Nagoya, a French-led European consortium will build a compact imaging polarimeter, and a large SRON-led international consortium will design and implement the largest and most complex instrument, the far-infrared spectrometer SAFARI.

SPICA will be used by the world-wide astronomical community. As is the custom for other great ground based and space observatories all astronomers can propose observations. A panel of independent specialists will rate the proposals according to their scientific quality and determine if and how much time will be awarded for the observations. Proposers will have about a year proprietary access to the measurement, after that period the data are made public to be used by anyone that is interested.”

David Naylor and Doug Johnstone attended the SPICA/SAFARI consortium meeting in Groningen at the end of May, where they were able to partake in the celebration of this significant milestone and actively engage in discussions around the critical paths forward. David Naylor provided an extremely well received report on the progress of the Canadian SAFARI instrument activities. Doug Johnstone also provided an update on the science case for time-domain research with SPICA.

In order to promote the science capabilities of SPICA and build additional enthusiasm and support amongst the international research community, there will be a dedicated international science conference next year on the island of Crete, “Exploring the Infrared Universe: The Promise of SPICA”, 20-23 May 2019. While the project is still over a decade away, the next three years are pivotal in defining the instrumental requirements and observing modes, and we strongly encourage Canadian participation at this meeting.

The recent success of SPICA at ESA in Europe and the strong support for SPICA at JAXA in Japan bodes well for the mission. Canadian astronomers wishing to become more active with SPICA science should contact David Naylor or Doug Johnstone in order to be added to the Canadian SPICA mailing list and/or to be put in contact with like-minded researchers within the SPICA consortium.
