There is a great list of lessons and resources which can be found here: Future Engineers: Name the Rover Challenge. It is worth mentioning that Future Engineers is a website that hosts several types of engineering challenges. If you register as a teacher, you'll gain access to challenges as they are made available, and you'll be able to create your own classes on the website to assign challenges too. This will share the challenge and all of its curated resources with each student for you to track their progress through the challenge. Once you've registered, you can set up your classes in your dashboard which will give you an access code to register your students. You'll find the parent permission form available both in email and printable form to save you time! Students can submit through their class portal or you can submit for them from the dashboard.
If you'd like some information about the history of naming spacecraft to help you and/or your students as you start this challenge, here are a few links below:
