I didn't get in until after the commercial break (I was in the city buying lots of anime stuff), so I missed the entire first half of the episode. What follows is a summary of about the last ten minutes or so of the episode.
-We see the space shuttle taking off, with Musashi and Kojirou in the pilot's seat. As the rocket roars upward, it jolts to a stop. Musashi-tachi look outside to see what's wrong, and they see a bunch of Yajiron, stopping the rocket with their telekenetic abilities!
-As Team Rocket is occupied by their thwarted hijacking attempt, Masato and Fuu are in the back, tied up. They look over and see Satoshi's Heigani, hiding underneath a shelf or something like that. The pokemon motions for them to be quiet so that nobody notices that there's a stowaway on the shuttle.
-Team Rocket is still occupied in the driver's seat, wondering what to do with the Yajiron. Suddenly, their bodies start to glow as they are lifted off the ground! Fuu's Solrock, whose trainer is now free, uses its psychic powers to throw the Rocket trio around the shuttle for a bit. Fuu then gets on the radio system and tells his parents (the astronaut, Jin, and the woman operator, Rei) that he's OK. Ran, who's at the control center with Satoshi, Takeshi, and Haruka, is relieved to find out that her brother is safe.
-Jin then informs the group that the Yajiron won't be able to land the ship, so it will crash unless Fuu and Masato do something! Fuu tells his father that he's worked the simulator before, so he reckons that he can handle it. Masato says that he'll help too.
-So, the landing process begins. Jin talks the two boys through the process of landing the shuttle. After a stressful few minutes, in which we see the two young boys flipping switches as Heigani threatens to press one of the buttons at random, the shuttle finally makes a safe landing.
-As the shuttle lands, Team Rocket dizzily falls out of the rocket. However, Satoshi and the others are at the landing site, waiting for them! Haruka has her Wakashamo use some sort of fire attack to toast the Rocket trio. Then, Ran orders her Lunatone to use some ice attack on the three, which freezes them into the shape of a big "R." Finally, Satoshi's Pikachu uses Iron Tail, sending Team Rocket blasting off again.
-Later, we see Jin in the shuttle, attempting another take-off. This one is a success, and one of the twins comments that their dad can now search for pokemon in space. They then tell Satoshi that they're ready to fight, and the narrator tells us that Satoshi's battle for the seventh Houen League badge has just begun!
And that's it. Of course, since I didn't see the first half of the episode, a lot of the events/motivations for the events that happened are unclear to me. I plan to be able to watch next week's episode (since I missed both the fight against Senri and Nagi, and I'll have returned back to the States by the time they get to the eighth gym battle).
