RocketAcademy writes "Low-cost nanosatellites known as CubeSats were originally developed as educational projects for university students. Today, CubeSats are attracting increasing attention for their ability to tackle a wide variety of applications. NASA's innovative PhoneSat, which uses a Nexus cellphone as its primary processor, has won the Best of What's New Award from Popular Science.
Most CubeSats operate in Earth orbit, but interplanetary CubeSat missions are also gaining mindshare. A team at NASA's Jet Propulsion Laboratory proposed sending a
CubeSat mission to Phobos, on of Mars' moons, earlier this year. Now, a group of companies is proposing a non-profit private mission that could carry up to 27 CubeSats to Mars."
