Cat Scan of a Planet?

Not open for further replies.


So, has it been conceived to put multiple satillite constellations around some moons or planets in order to shot them with appropriate electromagnetic radiation and get a picture of the interior? I know we use seismic and man-made sound waves, but it seems like we could turn our cat-scan technology to work on a large scale.

Developing this technology could help to answer questions we have about the cores of Mars, the Moon, Europa, Enceladus, and the Asteroids.

Thoughts? :roll:


Similar, but different utilization. I worked on the TERRIERS satellite project at BU, back in the mid-90's, and it was based on a remote sensing platform that utilized MRI/CAT Scan algorithms for scanning the Ionosphere.

[TERRIERS: Tomographic Experiment using Radiative Recombinative Ionospheric EUV and Radio Sources. I built the Ground Support Equipment (GSE), and was the Material's Manager, 1995-1996.]


No using any electromagnetic radiation won't work for probing deep beyond say 100 ish km. The signal just gets absorbed.
But there is a way; use "earth"quakes! A network of seismometers measuring waves generated in the planet by quakes can be used to map interior. The algorithms used are similar to that used in CAT scans.

A similar method is used to determine the interior structure of the Sun and stars, but here we can see the surface vibrating.
I suppose you could do the same for a solid object. Measure the very tiny motions of the crust using laser altimeters in lots of places simultaneously with a fleet of spacecraft. By that's what seismometers do from the ground ... a lot simpler
