Listening to NPR about Insight landing, idea concerning self-drilling heat probe

I was listening to the interviewee describe how their heat-probe self-hammers itself into the surface of Mars.

​

I started wondering about energy efficiency. I drew this up. If it's novel and useful, it would be my will that it be in the public domain. If it's not novel, I'm sorry causing you inconvenience.

Weaknesses: works better in high gravity environment. low gravity environment requires a substantial tube length, mitigating utility.

Use whatever PE device you want, if a spring is not to your liking.\

​

Benefits vs method described in interview:

Firing the spring will not generate an upward force on the device itself as in the described method. The described method seems counter to the desired goal of burying the device.
