Keep an ear and eye out for some new developments from the outer space world of Virgin Galactic - the suborbital spaceliner group financially-fueled by Sir Richard Branson.

During last week’s Flight School 2007 held at the Aspen Institute in Colorado, Alex Tai, Chief Operating Officer for Virgin Galactic, hinted that there’s new news regarding that dynamic duo: SpaceShipTwo/White Knight 2. Both are under construction at Scaled Composites in Mojave, California.

Tai said the lawyers were having a final go at a “major supplier arrangement” for Virgin Galactic’s spaceship system. Word in the hallway is that the announcement likely revolves around an engine supplier for the huge White Knight 2 carrier plane.

Also, Tai spotlighted Virgin Fuels and laboratory level propellant that “burn green” - that is, they are more environmentally friendly.

Another tidbit wound up in my notes too. Tai suggested that something is forthcoming about the g-load profile on passengers riding SpaceShipTwo on future suborbital jaunts. Maybe less “grunt work” for those onboard in taking on reentry forces?
