Right now, my energy is going towards preparing Chapter 5 for localization. The translation process begins next week. We have extracted all the English text and we are now annotating it.

A large dust devil caught by the Mars Perseverance Rover on Sol 1531 (June 10th). The more visible part of the dust devil (center left) is leaning to the left, but if you look closely as you follow it up, it then arcs to the right.

Some good news for once. With the delay in the announcement of opportunity for NF5 from 2023 to hopefully next year, there was some concern that the possible mission list would change dramatically.
An Io observer is still recommended for the mission list for NF5.

A crescent Triton (left), moon of Neptune, from Voyager 2 in 1989, and a crescent Pluto from New Horizons in 2015. This illustrates just how much rougher the surface of Pluto is than the melted-down Triton.

JIRAM and JunoCam onboard Juno observed a volcanic eruption near Io's South Pole ("West Illyrikon"). The energy output by this eruption appears to exceed the previous largest observed eruption on Io at Surt in February 2001.

Even by the standards of Io, the most volcanic celestial body in the solar system, recent events observed on the Jovian moon are extreme.

40 yrs ago the ESA Giotto spacecraft was launched to Halley's Comet and later became first spacecraft to flypast and image a comet nucleus.
Built in the UK, seen here being tested.
