Planet Trip is all about how we will get beyond the Moon and to the other planets. The first stop will be Mars.

But before you can get to Mars you need to build and prepare your craft. The authors suggested that to combat the problems of weightlessness, you will rotate the ship while it traveled. The inner ship would remain weightless while the outer ring revolved.
From my experience with these books this one is one of the earlier if not the earliest non-fiction children's book focusing solely on a manned trip to Mars. There were other books about Mars but this one lays out the mission in detail.
The landing is a combination of retrorocket and parachute. Mars looks like a mud-cracked desert (with plants in the cracks!) I have been told this mud-cracked appearance is a leftover from the Destination Moon movie where they put in cracks to give the moon set some depth and dimension. So the astronauts immediately go to collect samples.
Since this is just a sample run they quickly return to their ship for a return to the orbiting Mothership.
When we have finished conquering Mars, then it will be on to Venus where the authors admit we know very little about it (except of course they have great calamari!)
And what is beyond the inner planets? Of course it is onwards to the outer planets and the stars next week in the fourth book of the quartet: Beyond Mars.
