Mars InSight mission data from SEIS - Now OPEN to the public

First data release from InSight’s SEIS available from the IRIS DMC

In a key milestone for the InSight mission to Mars, the first data from the SEIS (Seismic Experiment for Internal Structure) instrument is now available from the IRIS DMC, in parallel with the NASA’s PDS (Planetary Data System) and the IPGP’s MSDS (Mars SEIS Data Service).

For detailed information, see: SEIS: Insight’s Seismic Experiment for Internal Structure of Mars

What you need to know

  • These data are from late November 2018 through February 2019.
  • The FDSN network designation needed to access the data is XB, (assigned for 2016-2022).
  • No naturally occurring seismic events have yet been detected during the time period covered by this first release. The first reported Marsquakes are included in data releases that will occur later in 2019.
  • The earliest data were collected prior to the final configuration and installation, and include times while the instrument was still on the lander deck, before the outer wind/thermal shielding was in place, while the HP3 heat probe was hammering into the ground (starting Feb. 28th), etc. This release is very exciting, but caution is suggested when interpreting these data.
  • The seismometer is equipped with both a long-period three-axis Very Broad Band (VBB) instrument and a three-axis short-period (SP) instrument.
  • There are multiple station designations as follows:
Station code Description
——————— ——————————————————————————————————-
ELYSE Scientific data from final configuration
ELYHK Housekeeping (aka State of Health) data from final configuration
ELYS0 Scientific data from postlanding before instrument deployment
ELYH0 Housekeeping (aka State of Health) data from postlanding before instrument deployment

How to access these data at the IRIS DMC

  • For a complete listing of the seismic data time series data at the DMC, use the irisws-availability service with these parameters that lists the channel and location codes that can be used to request the data.

  • To extract miniSEED data from the DMC using the fdsnws-dataselect service, here is an example webservice request.
  • If you need help with requesting data, please email engine_room@iris.washington.edu and we will assist you.

Education and public outreach

IRIS is an Educational Partner on the InSight Mission, with the goal of engaging students with seismic data from Mars. Classrooms will be able to stream Martian seismic data, allowing students to watch for marsquakes and meteorite impacts with us! In addition, we offer lessons and materials for students to learn about earthquakes, moonquakes, and marsquakes! Learn more at our InSight project page.

NASA’s InSight Mars lander acquired this image of the area in front of the lander using its lander-mounted, Instrument Context Camera (ICC).

This image was acquired on May 16, 2019, Sol 166 of the InSight mission where the local mean solar time for the image exposures was 16:40:39.317 PM. Each ICC image has a field of view of 124 × 124 degrees.
