ARD Questions
I've been reading on ARD lately and wondering why NASA and ESA haven't
reevaluated working from the ARD technology to build a cheap CRV. It seems like they could get it done faster then any other option. I have read what I could find on ARD but I have some questions maybe someone might know. Bear with me, I just a fan. ARD was 80% the size of an Apollo CM, but could a 1:1 CM scale ARD have fit atop an Ariane V stack? It looks like it would be too narrow by abotu .6m for the normal shroud. Could it fit in the shuttle cargo bay? The ARD program already had its own avionics, tps, chutes, flotation, and other subsystems. How hard would this have been to integrate into an enlarged version? This would seem to save time and give a chance at having a CRV ready before 2006. A silly question: on the actual ARD suborbital test, (I didn't find the G-loads the capsule took on descent), could an astronaut have survived inside with an O2 bottle and a mask? Jon |
