I don’t know if it will be on NASA TV since I don’t see anything listed for it on their schedule. I’ll go ahead and throw up the link.

Watching the webcam and the gal looks like she is a scifi dominatrix with a spike wrist band and futuristic outfit with leather straps. Glad NASA is out of the space business. Much more polished presentation and product.
They're probably too busy doing moslem outreach.
