The Bio-Dome is one of the three outlying structures besides the main Moon base. It is left of the main base. The other two are the Research Station and the Rock lab. The Research Station is directly up from the main base. The Rock Lab is up and across to the left, directly above the Bio-Dome.
You will have to go to the Research Station to recover the Tracking device from the Infirmary. Then you can go to the Bio-Dome to find Salerno. Then finally to the Rock Lab when you are chasing her. To enter the Rock lab, you must have purple eyes to fool the retina security scan, and you need the Keycard dropped by Salerno when she gets away from you.
There are two: - the BioDome is the second place you travel to in the rover. - the circular Infirmary is part of the Research Lab, the first place you go.
The entrance is at the left side of the main base. There are entrances at the bottom of the Research Lab, at the bottom of the BioDome, and at the left side of the Rock lab.
The yellow artifact (gem tower) is just above the Research Lab in the upper right of the lunar map. However, there is no value in going to it. The Red artifact is below the BioDome, and the Green artifact is just below the main lunar base.
When you find Salerno at the BioDome, she escapes through the airlock, and drops her keycard. If you have already turned your eye color to purple to beat the retina scan, you can follow her into the Rock lab.
Lunar Colony
There are no guards at all on Lunar Colony. PASE doesn't have any money in the budget.
Only Salerno still has a key card to enter the Rock Lab, but she can apparently get in without one. You only get a keycard when she drops hers at the BioDome. You cannot enter the Rock lab until then. Get the locator device from the Infirmary and you can track her down.
Lunar Colony became the 29th island released in Poptropica (not counting mini-quests) on September 6, 2012.
It is on the back of the lunar rover. To use it, click it and carry the hook to where you need it.
You turn them purple.
It is attached to the back of the lunar rover. To use it, click it and carry the hook to where you need it.
Once you have recovered the Locator Device, you will find her in the upper room at the BioDome. But she escapes. Pick up her keycard and follow her to the Rock Lab. Get the geiger counter in the storage room (upper room at far right). When you use the counter to find the artifact, she will show up again.
