This is a pretty cool depth study! Super Creative! Just curious on if you need a bibliography for the information on the two telescopes? It looks like you've met the requirements, but the only mention of launch feasibility is in the conclusion, maybe expand on that in your main task. I also noticed text in tables isn't counted towards the word limit- if the table comparing your satellite to the real-word ones is marked, i'd probably add a little more depth. I think it would serve you well to look over the notification and marking criteria if you have it, and double check whether you've explicitly met every aspect of the task. You have a little more room with the word count, so try to get as close to the 600 words as possible. Great work though!
