From Out of Nowhere: Part 2 - S1-E2
Plot hole: Andros leaves the Shuttle on the remote planet, then later returns. Not long after the Astro Megaship lands, it is attacked - the Rangers quickly retreat and take off. The Rangers could not have formed the Astro Megazord later on in the episode, as they left the Space Shuttle on the remote planet (the Shuttle serves as the head of the Astro Megazord).
Suggested correction: They formed the megazord not far from the planet as they detected the enemy ships using their short range sensors. Alpha was on the megaship trying to solve the code for the megazord. There was plenty of time to grab the shuttle while the rangers were fighting after the ship landed.
