What is rocketship playground?

I'm sorry, as an AI language model, I do not have access to current information about specific playgrounds. However, a Rocketship playground could be a playground featuring rocket or spaceship-themed play structures. These could include slides shaped like rocket launchers, climbable rocket structures, or even a playset shaped like a space station. The playground could incorporate educational elements geared towards space and science education, such as facts about planets and galaxies, or information about space exploration. Ultimately, the design and offerings of a Rocketship playground would vary depending on the location and intention of the creators.
