Gear Cube involve either half turns or a full rotation. It has six stationary centers, each with a different color, that always stay opposite from another specific center. White is always opposite of yellow. Blue is always opposite of green. Red is always opposite of purple. Each center determines what color that side will be. The centers are exactly based on the original Rubik's Cube. They are connected by a three dimensional cross with screws and springs allowing for less tension. Many cube solvers use the same notation when completing a cube, whether they are working on the original Rubik's Cube, the
Mars Cube One is to test new miniaturized communication and navigation technologies. They were able to provide real-time communication relay while the "InSight" lander was in the entry, descent, landing phase. The MarCO spacecraft were launched as a pair for redundancy, and flew at either side of "InSight". While there are a large number of CubeSats around Earth, Mars Cube One is the first CubeSat mission to go beyond Earth orbit. This allowed for collection of unique data outside of the Earth's atmosphere and orbit. In addition to serving as communications relays, they also tested the CubeSat components' endurance and navigation capabilities in
