I dont think you can.
There is no such power. You can fly on the hovercraft into the mud swamp, and in space aboard the Astro Zone ships. (see related questions)
by going to astro knights and enter the number in the ship and fly to the moon and build a ship and fly around finding planets.
you type 52,56 then you fly.
you get the spaceship ( it is in the swamp place), and you fly around in outer space and then, if you can find the metal jungle planet, you just fly around to the right for awhile.
In order to get to the lava planet on Poptropica's Astro Knights, you must fly to the sun. From there, you must fly diagonally in the right direction. You should come across the lava planet.
You can reach space by fixing the crashed saucer Excalibur, and get a new spaceship at the Pewter Moon. (see related questions)
it matters what you've done
you get the green stuff an dthen put it in
they are coordinates to fly the ship in the mudA pop. winner
Go to the crashed saucer. You will see that it needs a new fuel rod, and there is a place to enter the coordinates to outer space locations. If you fix it and get the X and Y numbers you need, you can fly into space.
Just fly all the way south toward the asteroid belt. Just search for a big glowing asteroid. It takes a little while to find it though.
Get in your space ship and fly down to earth
