I highly recommend this book...dang near required reading for low cost booster design...by John R. London III: LEO On The Cheap, http://www.dunnspace.com/leo-1-10.pdf (12.18MB please forgive the OCR glitches...it could do with a new scan by a program that knows how to look for the obvious alternative to the gibberish, "effikency". It is still very readable and informative.)
Prochron: Intended to launch 3kg (i.e.: a Cubesat to orbit, and, stripped of its upper stages, operate as an amateur sounding rocket under Canadian Association of Rocketry (Level 4) or National Association of Rocketry (Level 3). The payload is 0.1m square in diameter.
Symtex: A niche booster intended to span the gap between the Cubesat and Orbital's Pegasus, currently the smallest commercial orbital booster (20kg to 500kg). If followed in this order, the Ascent Roadmap follows the convention of using the core of the smaller booster, with modifications, as the strap-on stage for the next booster in the line. The diameter is 0.6m.
Kilder: This booster launches about 2000kg to 8000kg, and would be in competition with several existing boosters (Soyuz, Vega, Taurus, Delta II, and others.) It is 2.0m in diameter.
Lilmax: This booster launches from 20 to 60 tonnes to orbit, and has received the most attention because After Columbia Project, author of the Ascent Roadmap, has done Mars studies, to which this booster best applies. Its 4m diameter is the maximum possible highway transportable diameter. The fairing might be wider, and possibly some larger upper stages. The version that launches ACMD's Stampede Lander would have a 6.5m diameter fairing.
Bluestar: The oldest booster concept in the series has evolved the most since it was first examined. The only hard items are that it launches an 8000kg payload, is fully reusable and easy to operate by a potential vendor of charter space services. The payload envelope is required to be 3.0m by 8.0m, but may be a bit larger in the latest concept.
Freezerburn: The least well defined booster in the series launches 100 tonnes or more. Currently, the core is formed by linking four Lilmax modules together. Lilmax modules are then strapped onto the sides, while the upper stage and fairing are about 9m in diameter, leaving an 8m internal diameter available to the payload.
