SkyCube will take low-resolution pictures of the Earth and broadcast simple messages uploaded by sponsors.  After 90 days, it will use an 8-gram CO2 cartridge to inflate a 10-foot (3-meter) diameter balloon coated with highly reflective titanium dioxide powder.  SkyCube’s balloon will make the satellite as bright as the Hubble Space Telescope or a first-magnitude star.  You’ll be able to see it with your own eyes, sailing across the sky.  But SkyCube’s balloon isn’t just for visibility.  It will - within 3 weeks - bring SkyCube down from orbit due to atmospheric drag, ending the mission cleanly in a fiery “grand finale” that avoids any buildup of space debris.
