If it shakes or quakes, let's visit it with seismometers!
InSight data were used to determine that Mars has a ~600 km solid inner core. A bit of a surprise and also a bit of a quandary given earlier studies found a molten silicate layer at the base of the mantle. We need a martian seismic network! Read my News and Views here: rdcu.be/eDVOJ
Marsquakes indicate that the inner core of the red planet is solid, not liquid | Nature
An analysis of seismic waves propagating through Mars finds evidence that the planet has a small, solid inner core, which challenges existing planetary models.

PSA: The OMB has been directing NASA to shut down services at Goddard Space Flight Center, including all cafeterias, vending, the health center, etc. Now they are ending internships for early careers only at GSFC. Is this how we want to invest in the future of our nation's space exploration program?

Check out my latest paper with Tom Watters at the Smithsonian! We used the exposure ages of boulders and landslides visited by the Apollo 17 astronauts in the Taurus-Littrow Valley to work out the size and frequency of the moonquakes from a nearby fault scarp. cmns.umd.edu/news-events/...

A new study shows that seismic activity on the moon could pose risk to long-term lunar infrastructure.

56 years ago today humans walked on the Moon for the first time. Cannot wait to go back!

Happy #NationalMoonDay! 🌕 🌙 🌓 🌑
Let’s look at the Moon’s crust, which may be thinner than originally thought.

It was 56 years ago today Neil Armstrong first stepped on the moon — a worldwide event that millions tuned into, including me and my brother (even if I did fall asleep). It’s a big reason we became astronauts and a great example of what our country can do when we work together.

My latest hobby? Taking pictures with my S50 Seestar telescope. A bit of the North America Nebula (on July 4th nonetheless)!

I've been away from social media for half a decade. BlueSky seems *less bad*. Going to test the waters.
