According to the image caption this article seems to be based on ESA's GOCE mission (2009-2013)[0]. "Detailed analysis of GOCE's thruster and accelerometer data serendipitously revealed that it had detected the infrasound waves generated by the 2011 Tōhoku earthquake (whereupon it inadvertently became the first seismograph in orbit)." [0][1] There's also NASA's GRACE mission (2002-2017) which has been relaunched (GRACE-FO, 2018) with almost identical hardware [2]: "GRACE measures time variations while GOCE measures the static gravity field."
