Sampling the volcanic plumes at Io: Impact speeds and shock conditions
Meteoritics &Planetary Science, Volume 61, Issue 2, Page 241-271, February 2026.Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...
