David Saint-JacquesOC OQ FRCGS[2] (Quebec French:[davɪdsẽɪ̯̃nʒã(ŋ)k̚],French pronunciation:[davidsɛ̃ʒak]; born 6 January 1970)[3] is a Canadianastronaut with theCanadian Space Agency (CSA). He is also anastrophysicist,engineer, and aphysician.
In December 2018, he launched to theInternational Space Station, as flight engineer on Expeditions57,58 and59; he returned to Earth on 25 June 2019.

Saint-Jacques was selected in May 2009 by theCanadian Space Agency (CSA) as one of twoCSA astronaut positions, after a long process selection attended by 5,351 candidates, and moved toHouston to be one of 14 members of the20th NASA astronaut class.[4][5] He then graduated fromAstronaut Candidate Training that includedscientific andtechnical briefings, intensive instruction inInternational Space Station systems,extravehicular activity (EVA),robotics,physiological training,T-38flight training,Russian language and water and wildernesssurvival training. Since graduation, he has been assigned to the Robotics Branch of theAstronaut Office.[4]
On 19 September 2011,NASA announced that Saint-Jacques would serve as anaquanaut aboard theAquariusunderwater laboratory during theNEEMO 15 undersea exploration mission from 17–30 October 2011.[6] Delayed by stormy weather and high seas, the mission began on 20 October 2011.[7][8] On the afternoon of 21 October, Saint-Jacques and his crewmates officially became aquanauts, having spent over 24 hours underwater. NEEMO 15 ended early on 26 October due to the approach ofHurricane Rina.[7]
In 2013, Saint-Jacques served as cavenaut into theESA CAVES[9] training inSardinia, alongsideSoichi Noguchi,Andreas Mogensen,Nikolai Tikhonov,Andrew Feustel andMichael Fincke.


In May 2016 Saint-Jacques was selected as a member of ISSExpedition 58/59, which at the time was scheduled to start in November 2018.[10]
On 3 December 2018, Saint-Jacques launched to the ISS on boardSoyuz MS-11, alongside commanderOleg Kononenko and fellow flight engineerAnne McClain.[11] He became a member of theExpedition 57 crew for two weeks before transferring to Expedition 58, which officially started on 20 December 2018 when theExpedition 57 crew left the station. Saint-Jacques, Kononenko and McClain subsequently transferred to Expedition 59 on 14 March 2019 with the arrival ofSoyuz MS-12.
On 8 April 2019, Saint-Jacques conducted his firstspacewalk,[12] becoming the fourth Canadian astronaut to take part in anEVA and the first to do so in 12 years. The spacewalk lasted roughly seven hours.[13]
Saint-Jacques, McClain and Kononenko returned to Earth on board Soyuz MS-11 on 24 June 2019.[1]
Saint-Jacques holds aBachelor of Engineering inEngineering Physics from theÉcole polytechnique de Montréal, an affiliated college ofUniversité de Montréal, where he graduated in 1993.[3] He later graduated in 1998 with aDoctor of Philosophy inastrophysics,[14] from theCavendish Astrophysics Group atCorpus Christi College, Cambridge. Saint-Jacques completedpostdoctoral research at theNational Astronomical Observatory of Japan between 1999 and 2001, where he worked on the development and application of theMitakaInfrared Interferometer in Japan and theSubaru Telescope Adaptive Optics System inHawaii.[4][5][15] He also holds aDoctor of Medicine fromUniversité Laval completed in 2005[16] and completed aFamily medicineresidency atMcGill University (2007) (specializing infirst-line,isolatedmedical practice).[3]
His broad scientific background includesengineering,astrophysics and medical training, with international experience in France and Hungary for engineering study andLebanon andGuatemala for medical study.[4] Saint-Jacques is affiliated with the Collège des médecins du Québec, theCollege of Family Physicians of Canada,Ordre des ingénieurs du Québec,International Society for Optical Engineering, and theCambridge Philosophical Society as a Life Fellow.[4] Saint-Jacques began his career in 1996 as abiomedical engineer at the Quebec firm Electromed with secondment toLariboisière Hospital, working on the design ofradiologicalequipment forangiography andimage analysisalgorithms of cineangiography.[4][5]
From 1994 to 1998, his studies includedtheoretical work onastronomical observation and design, fabrication and commissioning of instruments for theCambridge Optical Aperture Synthesis Telescope and for theWilliam Herschel Telescope in theCanary Islands.[4] During the course of this research undersupervisorJohn E. Baldwin he made several trips abroad on sponsorship from theParticle Physics and Astronomy Research Council, theCavendish Astrophysics Group,Corpus Christi College and theCambridge Philosophical Society, and decided to pursuefurther research experience in Japan.[14] In 2001, he joined the Astrophysics group at theDepartment dephysique,Université de Montréal.[4][17]
Prior to joining theCanadian Space Program, Saint-Jacques was amedical doctor and the Co-chief of Medicine at Inuulitsivik Health Centre inPuvirnituq, Quebec since 2007. He also worked as aClinicalFacultyLecturer forMcGill University's Faculty of Medicine, supervisingmedical trainees inNunavik.[3]
Saint-Jacques was born inQuebec City and raised in Montreal.[18] Saint-Jacques is married to Dr. Véronique Morin and has three children.[19] He is a lifelong mountaineer, hiker, cyclist, skier, and sailor.[3][4] He also holds acommercial pilot license.[4] He is fluent in French and English, and has a basic understanding of Russian, Spanish and Japanese.[3][4][20]
