Other groups from around the world also did some very interesting experiments. Ivanna H. and many more kids from Barranquilla, Colombia, sent up Bitter Palm seeds and tardigrades on the rocket to see if there was a difference when they came back. There are also experiments from Ecuador. One that went up on the rocket was testing how kinetic sand could hold up during rocket launch because kinetic sand is used in relieving stress, and astronauts have a lot of stress while in space. Canada also had a large group representing. Their experiment was testing how vibration and acceleration would affect the density of teeth. Another experiment I really liked was by Dagmar D. from Pennsylvania. Her experiment was testing the intraocular pressure to eyes during spaceflight looking to see if glaucoma might arise. I think this is a smart experiment because this could be very detrimental to astronauts if there is an increased chance of getting glaucoma. This is the second experiment she’s had with Cubes In Space; last year she did the same experiment, but this year she revised her experiment slightly. Her sister, Diamante D., also had an experiment going up on the rocket. Her experiment was testing different kinds of fish scales to see if the fish eating algae made a difference in how they held up in space conditions. An experiment that is similar to our computer cube was done by Alexander Caylor, also from Pennsylvania. He was looking at which kind of storage is better: analog or digital. It’s like ours because both are looking at data storage, except ours is powered during flight while his is not. This year was also the third year for one of the participants, Emerson Dycus from Green Bay, Wisconsin. Her experiment this year is testing organism dormancy for growing food on future planetary colonies, such as Mars.
