Information Week: "Aiming to supplement research on the feasibility of long-term space flight for humans," The Mars Society has chosen a Mars Project Challenge proposal to explore the use of artificial gravity that will employ CubeSats.
Mars Society president Robert Zubrin said that while space agencies around the world have 'chosen to study the effects of zero gravity on humans with no end in sight,' his group seeks to develop technology to provide humans with gravity in space....
The details about the craft's configuration and the project's schedule have not yet been determined. [Tom] Hill [of the Mars Society] will manage the project.
The project name is "Tethered Experiment for Mars inter-Planetary Operations (TEMPO 3 or TEMPO cubed)," according to the Information Week report.
