Copenhagen Suborbitals: Sapphire rocket update

Copenhagen Suborbitals posts a video about their Sapphire rocket project. From the video caption:

Copenhagen Suborbitals is just weeks away from our first actively guided rocket flight. The Sapphire rocket has a liftoff mass of 200 kg, and stands six meters tall. Its nitrous oxide / polyurethane HATV type hybrid, controlled by servo operated copper jet vanes in the rocket jet. These powerful motors have a flawless record.

The instrumentation and payload is now passing parachute separation tests – and the two test performed confirmed our expectations for the parachute system.

The purpose of Copenhagen Suborbitals is to launch a human into space. You can god to space with a passive stable finn only rocket – but the initial acceleration needed to stay on course is too high for humans to endure. Therefore CS must master active guidance.

The fist and last purpose of the Sapphire mission is to test active guidance.

The Rocket Company: free ebook & serialization

In 2003 HobbySpace presented a serialized version of the book The Rocket Company by Patrick J. G. Stiennon and David M. Hoerr , with illustrations by Doug Birkholz. Subsequently, the book was accepted for publication by the AIAA and released in the summer of 2005. The printed version contained revised and updated materials, a new chapter, and over 30 illustrations.

The Rocket Company is a fictional account of the development of a commercial two stage to orbit (TSTO) reusable launch vehicle (RLV). Included is a description of the business model devised by a group of seven fictional investors committed to creating an economic engine that will cause the cost of space transportation to spiral rapidly downward as the market for launch services expands. In this context, the marketing, regulatory, and technical problems facing any serious attempt to reduce the cost of space transportation are explored. Although a work of fiction, the book follows in the vein of non-fictional accounts of the development of successful technological products and businesses, such as The Soul of a New Machine, and American Steel.

To bring more readers to the book, and to the ideas it offers for space transport development and business model, the authors are offering free access today to the updated electronic version of the book: The Rocket Company eBook by Patrick Stiennon, David Hoerr, Peter Diamandis, Doug Birkhol: Kindle Store/Amazon.com

In addition, the authors are letting me temporarily re-serialize the updated version. Today you can obtain here the following sections of the book:

 

Video: USC rocket propulsion lab tests Kiwi motor

The University of Southern California Rocket Propulsion Laboratory (USCRPL) “is an undergraduate research laboratory that designs, builds and tests experimental rocketry and propulsion hardware”.  They are carrying out tests in Mojave of their rockets and rocket components and yesterday they posted the following (via Ben Brockert): Twitter / USCRPL:
