15th International Space Station (ISS) mission, six months in length, began with an April 9 docking. Spring experiments included algorithm testing and improvement for autonomous control and formation flying of three satellites operating simultaneously inside.

1 million per acre is the expected concentration of three species of 17-year cicadas in the Chicago area. Site has audio and an interactive emergence map. Click Cicada Mania! at the Lake County Forest Preserve District (north of Chicago). www.lcfpd.org
110 years after discovery of a multi-dimensional mathematical object called E8, the mapping was completed, a task that created 64 times the information inside the 1 GB Human Genome. On paper, the four-year team-based calculation is the size of Manhattan and will likely change understanding in algebra, geometry, number theory, physics and chemistry, and in engineering that uses those sciences. www.aimath.org
