Editor's note: JPL is having an interesting live video stream from the white room where Mars Science Laboratory is being prepared for launch. JPL PAO's Veronica McGregor just posted a heads up on Twitter - you can view the event live here on USTREAM TV
But unless you use Twitter or knew to look at JPL's home page today and saw "Readying for Mars: Live 'Clean Room Cam' and Chat" you would not even know that this was going on. No media advisories or press releases were issued. There is no mention on the MSL website at JPL or here on NASA.gov's media site - or anywhere else on NASA.gov so far as I can tell.
It is great that JPL is trying new stuff out, but they should not leave the rest of the world behind when it comes to informing people as to what it is doing.
