Mini Satellites Could Revolutionize Space Industry

An anonymous reader writes "Space Daily reports that University of Toronto researchers are working on a project that could replace conventional satellites with a miniature version no larger than a milk carton. From the article: "At only 3.5 kilograms, the Canadian Advanced Nanospace eXperiment 2 (CanX-2) will test small, low-power devices that could lay the groundwork for flying formations of small satellites that could eventually replace larger, more expensive satellites."

Two Danish micro satellites.

[Saggi]

Denmark has all ready send two micro satellites. They measure only 10x10x10 cm!

They were send up 30. June 2003, along with some commercial satellites and were created as student experiments from "Danmarks Tekniske Universitet" (DTU) and "Aalborg Universitet" (AAU). The goal was to see if you could bring them up there and communicate with them.

escape velocity for microsatellites with ion drive

[zardo]

I think somebody needs to develop an ion engine for micro-satellites, then universities may be able to afford rockets like the spacex falcon1 which puts their satellite into low-earth orbit, where it uses the ion engine to build up its speed for escape velocity. Perhaps this is the next "killer app" for these private space enthusiasts. So far JPL is the only place to find a highly efficient ion engine. They just came up with a high efficiency, high-power design for project prometheus. Ion engine micro-satellite, watch for them.
