The series now well underway, by issue #6 a pattern has developed, or a rhythm, if you will: the series alternates between more or less science-fiction thrillers based on Earth technology, mystery and events and episodes that focus on the alien Vineans.
And in this re-read, if it was the Vineans that got me hooked, in the long run I find the human-based episodes more satisfying.
Which is a pity, because in episode #6 we are back in Vinea – literally.

The 1976 entry, Les Trois soleils de Vinéa, will be published in English as the eleventh episode, as The three suns of Vinea.

To racap – the Vineans fled their world due to the instability of their star, and founded a colony on Earth, that first fell under the control of a rogue AI, and then was menaced by an authoritarian faction.
Now, the Vineans are going back to their home planet, to check if after millennia it is again capable of sustaining life. Yoke, as usual with Vic and Pol in tow, comes along for the ride.
They find the planet in locked rotation – one side a desert, the other frozen.
There are survivors on the planet, who have rebuilt a rather primitive civilization, and are under the control of a “god” that turns out to be a rogue AI.

All things considered this is a solid episode, full of technology, and with an abundant serving of astronomical information, in easily digestible bits for the younger readers. It is also a very Star Trek-y episode, with Yoko and her team solving problems with diplomacy and ideas, rather than by zapping the bad guys (although a fair amount of zapping takes place anyway).
As for hardware, we get variants on the Vineans spacecraft, and some nicely designed robots.

For some mysterious reasons, some plates portray Yoko and her Vinean friend Khany in a suggestive way that has contributed through the years to the fan theory that Yoko is bisexual.
And I mean, who can tell?
But I doubt that Roger LeLoup would explicitly go in that direction in a kids comic in the ’70s.
Or would he?
