Developing a Galaxy <br /><br />By Dan Cohen<br />Program Manager<br /> <br />(To see a size comparison between Galaxy, Genesis and the future complex modules planned by Bigelow Aerospace, click here .)<br />Bigelow Aerospace has kicked off development of the Galaxy advanced technology demonstration program, which is intended to be launch-ready in the fall of 2008.<br />Galaxy will bridge the evolutionary development between the Genesis-class vehicles and the vehicle to follow — our first human-inhabitable module, Sundancer. Galaxy’s primary purpose is to provide critical risk reduction, as well as first-flight experience for technologies being developed and intended to be flown on Sundancer and our operational fleet of standard-sized vehicles.<br />While we will leverage proven processes and technology learned in the development and flight of Genesis I and II, a number of technological advances will be implemented on Galaxy. These include:<br />· Advanced onboard avionics: Features increased performance, reconfigurability, decentralized processing, superior redundancy capabilities and “plug and play” features to speed integration and testing while improving reliability.<br />· Key elements of the Environmental Control Life Support System (ECLSS): While Galaxy will not need to support human passengers, it serves as an ideal test-bed to flight-qualify critical elements of our life- and crew-support systems in zero-gravity.<br />· Upgraded attitude determination and control system: Our basic Genesis-class guidance, navigation and control system will be upgraded to provide greater torque-control authority and momentum management with precision attitude sensing.<br />· Increased communications bandwidth: The addition of higher-speed communications bands for uplink and downlink will provide f <div class="Discussion_UserSignature"> <font color="#993300"><span class="body"><font size="2" color="#3366ff"><div align="center">. </div><div align="center">Never roll in the mud with a pig.

One step at a time they're building a revolution. I could easily see the Sundancer being the control module of an interplanetary spaceship.<br /><br />That said: Genesis II has been put off 'til late may due to a mandatory mod being done on the Dnepr rocket. <div class="Discussion_UserSignature"> </div>

Except it (Galaxy) doesn't seem to handle a crew. <div class="Discussion_UserSignature"> <p> </p><p><font color="#0000ff"><em>"SCE to AUX" - John Aaron, curiosity pays off</em></font></p> </div>

"...but Sundancer is supposed to be able to handle a crew of 3."<br /><br />For sixth months. Is that right?

Nice that the numbers are close. Dragon and Sundancer would be a nice weekend villa with a great orbital view.<br /><br /><br />BTW:<br />Funny the article says that the Orion has no toilet. In a <br />previous post I think Shuttleguy said there would be one. <div class="Discussion_UserSignature"> <p> </p><p><font color="#0000ff"><em>"SCE to AUX" - John Aaron, curiosity pays off</em></font></p> </div>
