Chemical Space Gardens

You know that colorful crystal garden you grew as a kid?

Yeah, we do that in space now. 

Chemical Gardens, a new investigation aboard the International Space Station takes a classic science experiment to space with the hope of improving our understanding of gravity’s impact on their structural formation.

Here on Earth, chemical gardens are most often used to teach students about things like chemical reactions.

Chemical gardens form when dissolvable metal salts are placed in an aqueous solution containing anions such as silicate, borate, phosphate, or carbonate.

Delivered to the space station aboard SpaceX’S CRS-15 cargo mission, the samples for this experiment will be processed by crew members and grown throughout Expedition 56 before returning to Earth.

Results from this investigation could provide a better understanding of cement science and improvements to biomaterial devices used for scaffolding, for use both in space and on Earth.
