NASA's InSight Mission

IRIS is an Educational Partner on the InSight Mission, with the goal of engaging students with seismic data from Mars. As the data is released, classrooms will be able to stream Martian seismic data using IRIS tools, allowing students to watch for marsquakes and meteorite impacts with us!  Learn more about the mission on NASA's InSight page.

First Martian Data Release

InSight Release 1a, including raw seismic data from November 26, 2018 - February 28, 2019, will be released on May 24, 2019 at 12 PDT! It is important to remember this is a first release of uncalibrated data. There are no marsquakes or meteorite impacts thought to be recorded in these first three months. 

Mission milestones thus far:

There are multiple ways to access data. 

Mars Monitor

https://www.iris.edu/app/mars-monitor

The Mars Monitor, which is both mobile and desktop friendly, allows users to easily view seismic data from the InSight mission.  We preselected a single channel from the broadband seismometer after it was deployed on the surface of Mars.  While the data are not continuous, we chose this channel to maximize the data available.

jAmaSeis

Download our jAmaSeis software to stream the data in delayed real-time. We have made it easy to select the data channels that have the most data.  Channels may not be running continuously, so at times when you view the data, there may be gaps. During that time, data is being recorded on another channel.  The data coverage of one of our recommended data channels after the seismometer was deployed to the surface of Mars is plotted below.

Broadband Data Summary

These data include four station designations:

Data Release Schedule

More data and marsquakes are coming soon!

Seismic Data in the Classroom 

While we wait for marsquakes, now is the time to help students learn about earthquakes and seismic data! Once they understand the basics on Earth, they are prepared to become Martian scientists!  IRIS offers lessons, software, and tutorials to help you and your students prepare for the mission!

Software

jAmaSeis - jAmaSeis is a free, java-based program that allows users to obtain and display seismic data in real-time from either a local instrument or from remote stations.

App

Station Monitor - Explore earthquakes near you or from around the globe using the new IRIS Station Monitor app! Select from hundreds of seismic stations throughout the world. View up-to-the-minute recorded ground motions or see recordings from previous days and past events. Get information about recent events and choose to annotate wave arrivals.

Lessons

Earthquake Machine - Students collaborate in small groups to investigate how energy is stored elastically in rocks and released suddenly as an earthquake (the earthquake cycle). This activity emphasizes the role of mechanical models in understanding and testing ideas in science.

Build a Seismometer - In small groups of 3-4 students, design and construct a seismograph using common household and craft materials provided. Students will demonstrate to the class (by shaking their table) how their seismographs record motion (and if possible, the time of the disturbances).

Teachable Moments - IRIS Teachable Moments presentations capture that unplanned opportunity to bring knowledge, insight, and critical thinking to the classroom following a newsworthy earthquake.

Seismic Slinky - Students will produce P and S waves using a Slinky© to understand how seismic waves transfer energy as they travel through solids. All types of waves transmit energy, including beach waves, sound, light, and more. The velocity difference between the faster compressive P wave and the slower shearing S wave helps seismologists locate an earthquake’s epicenter.

Seismic Waves - Seismic Waves is a browser-based tool to visualize the propagation of seismic waves from historic earthquakes through Earth’s interior and around its surface. Easy-to-use controls speed-up, slow-down, or reverse the wave propagation. By carefully examining these seismic wave fronts and their propagation, the Seismic Waves tool illustrates how earthquakes can provide evidence that allows us to infer Earth’s interior structure.

IRIS Earthquake Browser - The IRIS Earthquake Browser (IEB) is an interactive map for exploring millions of seismic event epicenters (normally earthquakes) on a map of the world. Selections of up to 5000 events can also be viewed in 3D and freely rotated with the 3D Viewer companion tool.

Animations - IRIS has over 100 animations to help teach Earth science fundamentals from plate tectonics to seismic wave propogation. Content level ranges from non-scientists to those with college-level understanding of geology. Check out a general comparison of Mars vs Earth!
