A big Congrats to NASA for the 4 hour 24 minute test flight of the Delta 4 with the Orion Spacecraft's milestone journey of a new era of manned space exploration leading to Mars & beyond era!  8)

Orion Soars on First Flight Test  <-------- Video of the launch.






Earth from Orion!   8)







I am also proud to be a part of this text flight by having my name on a dime-sized microchip & also will be on future exploration flights & missions to Mars. Damn! I have 60k in space thus far, starting to be like that Howard guy!  :D  ;D

Very beautiful flight.  I watched a good portion of it live on NASA TV. 

My one gripe?  There have been MASSIVE technological improvements in this type of spacecraft since the Apollo program.  Especially in terms of computing power.  A Commodore 64 had more computing power than Apollo 11's onboard computer.  But we seriously can't figure out live HD video from the Orion spacecraft?

It boils down to bandwidth.  There's a fuckton of telemetry coming down from the spacecraft.  You should see some hi res stuff in a few days.
Peacekeeper, when it absolutely, positively has to be nuked in 30 minutes or less.  Or the next nuke's free!

Actually, it's probably a combination of factors.  No doubt, the telemetry package for Orion has to be massive.  Especially since NASA stated that they have as many as 1000 separate instrumentation readouts to relay.

But I work with technology on a daily basis that can compress a 1080i HD video signal down to 6 MHz for transmission via Ku or C band satellite uplink.  Hell, with the right encoding I can even stream live HD video by bundling together streaming data from 3 or 4 smartphones.  And considering the size of the antennae at the NASA tracking stations, they should have been more than capable of bringing in that signal even when the spacecraft was at it's apogee.

Bandwidth probably wasn't so much the issue.  More likely, it's one of the classic challenges of spaceflight:  weight.  The weight of the gear that would be needed for that type of HD video encoding was probably the deciding factor for NASA.  HD cameras, like GoPros, are really light.  But the transmission gear?  That's another story.  NASA has been using Standard Def video transmission gear on manned spaceflight for years and probably has some very light gear at their disposal.  As for cameras?  NASA very well may have had something like a GoPro onboard Orion.  I'd definitely like to see that footage.

I've worked with the same uplink/downlink system they are using.  Bandwidth is an issue.

Sounds like NASA needs to get some MPEG4 compression encoders.

Okay, what I am looking at here?   ???  Is that during re-entry?
