I remember reading a book in primary school about children going to Ganymede but I can't remember what it's called at all.

I can't remember much about the book; I seem to remember that the children snuck on the rocketship, but that's all I really remember. We read it in 2003 so it was definitely published then or before.

Potential answer, but I can't find a more complete synopsis

EDIT: Google Books allows a limited search-inside-book feature and this is definitely the correct answer for my half-remembered book. I hope it is what Emily was searching for, too. I can even confirm that the tree-stump-alikes were called the Soshtii.

It might be Ghost Ship to Ganymede by Robert Swindells. The only synopsis I can find for that title is,

Fay, Tom and Grover stow away on a spaceship and find to their horror
that they are en route to unexplored Ganymede, a moon of Jupiter.

(from Google Books)

Well that fits, as far as it goes.

I could have forgotten a third character. Mentioning that Ganymede is unexplored is a favourable point, and sets this book apart from many others; it certainly wasn't set on a well developed Ganymede as most stories seem to be. I forgot to be clear that the lifeforms in the canyons are previously unknown, and discovered by the children.

Robert Swindells apparently writes for the right age group, too. Room 13 was also his, for instance.

I can't find a library copy of Ghost Ship to Ganymede, a download (legal or otherwise), or a reasonably priced hard copy. I can only find some that are, for whatever reason, pushing the £1000 mark.

I wonder if the synopsis rings true with Emily as well? Perhaps she could perform an image search for that title, and see if any covers look familiar?

I'll also see if I can hunt down a copy by ringing some bookshops.

Must, consolidate, early, memories! Or, might, never, punctuate, properly, again!

Farmer in the Sky by Robert A. Heinlein

The story is set in a future, overcrowded Earth, where food is carefully rationed. Teenager William (Bill) Lermer lives with his widower father, George. George decides to emigrate to the farming colony on Ganymede, one of Jupiter's moons. After marrying Molly Kenyon, George embarks with Bill and Molly's daughter Peggy on the 'torchship' Mayflower. On the journey, Bill saves his bunkmates from asphyxiation by improvising a patch when a meteor punctures their compartment. During the trip all the children attend class; also, to combat the boredom of the long trip, the Boy Scouts among the passengers form troops.

I'm searching for very similar story on ganymede...travel was along frozen rivers on an ice skating type craft at high speeds driven by a pilot.....also the lifeforms found were quite gangly and rested in frames that supported them similar to a lounge chair ....my time frame was 1960's in elementary school
