Sampling the volcanic plumes at Io: Impact speeds and shock conditions

open access: yesMeteoritics &Planetary Science, EarlyView.
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 ...

More recently, some have defended that the
