Biological research payloads have been flown on several missions, with more planned. The need for such a small-factor satellite became apparent in unit 10 system design specifications pdf wiki student as a result of work done at Stanford University’s Space System Development Laboratory.
Desiring to shorten the development cycle experienced on OPAL and inspired by the picosatellites OPAL carried, Twiggs set out to find “how much could you reduce the size and still have a practical satellite”. The picosatellites on OPAL were 10. 5 cm, a size that was not conducive to covering all sides of the spacecraft with solar cells. A model of a launcher was developed for the new satellite using the same pusher-plate concept that had been used in the modified OPAL launcher. Twiggs presented the idea to Puig-Suari in the summer of 1999 and then at the Japan-U. Cal Poly published the standard in an effort led by aerospace engineering professor Jordi Puig-Suari.
