Jun 25, 2022 at 21:50 comment added user0193 @Cornelis Jupiter itself is radioactive
Jun 25, 2022 at 16:14 comment added Cornelis @CuteKItty_pleaseStopBArking Where did you get the "54000 times as much radiation" from ? I thought the magnetosphere of Jupiter protects Europa from the solar wind.

Jul 27, 2021 at 13:37 comment added Jeremy Friesner @user0193 IMHO we should be exploring both, but it's unreasonable to expect us to do so unless/until the necessary technology is available and working.

Jul 27, 2021 at 11:30 comment added user0193 @JeremyFriesner are you suggesting that we are searching in Mars because its possible (not because its desirable) while we should be searching in Europa or Enceladus?

Jul 25, 2021 at 20:06 comment added leftaroundabout Searching for life just one of many scientific objectives when it comes to exploring planets and moons. IMO it's not a very high-priority one, because it's actually rather likely that in our solar system there is only life on Earth. If anything, the possibility of there being life on Enceladus is reason not to go there before we have had the chance to look at it better by other passing-by missions, space telescopes etc..
Jul 25, 2021 at 14:07 comment added CuteKItty_pleaseStopBArking The main reason is how far (in delta-v) the icy moons are from Earth Orbit. Europa surface is 17.5km/s, which is 3 times as "far" as Mars surface, at 5.6km/s. but measured as Tsiolkovsky would, it is 13.3 times as "far". (13.3 times higher fuel ratio needed). Add to that the very interesting radiation environment of Europa (54000 times as much radiation as the stil-evacuated city of Pripyat, next to Chernobyl) makes for challenging engineering.

Jul 24, 2021 at 23:47 comment added user0193 @AlfonsoGonzalez thanks but its just another satellite, not surface or subsurface mission.
