Happy 2-year landiversary, @NASAPersevere! 🥳️
On Feb. 18, 2021, @NASA's six-wheeled explorer touched down on the surface of Mars after an ambitious (and nerve-racking) entry, descent, and landing. Here's to more years of science and trailblazing on the Red Planet!
We've been allocated additional funding from @spacegovuk, so are able to offer funded spots on our @NASAInSight observers' program to UK-based masters, PhD, and postdocs! Please share with your networks.

Perseverance has recorded the first sounds on Mars—dust devils. In the Nature Portfolio Astronomy Community, @Stott_Alex shares the recording and describes what it reveals about the dynamic nature of winds and dust in the Martian atmosphere. https://t.co/MPSqXwIFST
Please no one mention if "NASA ever thought of X" for the solar panels right now. Too raw. In short, the answer is yes but it wasn't worth the cost - missions have budgets.
Rest easy, little lander ❤
@NASAInSight's mission has ended after more than four years of detecting marsquakes, meteoroid impacts, and unique science on Mars. Congratulations - and thank you - to the team that made these pioneering discoveries possible. https://t.co/MCRzWYFSMd
New paper just out on @NASAPersevere audio recording of a dust devil! Check out this blog where I talk about what we did, how we did it and why we care so much about Mars winds and dust! https://t.co/as8pI0Q1pq
@exoseismologist@martijnende Haha - this runs the risk of us listing our favourite channels, events and papers in a convolved and confused manner. Very digestible
@martijnende@exoseismologist Oh wait you said less than 10 Hz. I replied for >10Hz sorry. The LF and BB ones typically have most signal 0.1-1 Hz and HF/VF above 1 Hz largest around 2.4 Hz. If you need polarisation you are quite limited in the number of events you can use (Look at @FynnMitsuki recent paper)
@martijnende@exoseismologist Look at the very largest VF type events. Especially horizontals have more power up there. We don't have many marsquakes with good snr at those frequencies. There are SF type events with snr there but these are short cracks in comparison
@martijnende BHU,V,W are the VBB seismometers. They need rotating to vertical north and east though, but the info should be in the dataless. Nominally the https://t.co/6RFYhychoz* should be there at 20sps. Let me know if there's still confusion, writing this on the fly
