Short summary
Our research introduces technology for exploring subglacial lakes while keeping them isolated from surface contamination. The RECoverable Autonomous Sonde (RECAS) can drill ice both downward and upward, allowing clean water sampling. In some cases, the sonde should drill at specific angles to follow a trajectory, maintain verticality, or bypass obstacles. This paper describes the general principles of steering the RECAS by adjusting the drill's heat distribution and the experimental results.
