Kosmoloty Sezon 1 Odcinek 39: Starling: Space Racer!

Aaaah-choo! Eagle comes down with a cold, and has to stay back in Stardust Bay while the other cadets get to test a new, highly advanced solar engine system on an obstacle course close to the Sun. Quickly growing bored with his rock collection and other mindless distractions, Eagle decides to do some research about the solar engines and the test mission. He finds out that Mercury’s orbit could block the sunlight and render the solar engines useless -- putting the cadets and teachers in danger! Will Eagle’s frantic warning reach the test pilots before Mercury casts its shadow on the obstacle course?
