Sending satellites into space is still pretty darn fascinating. DirecTV is sending up its next satellite today at 4:22PM PST.
Here's the satellite's spacecraft moving into position at the launchpad (it really gives you an idea of how massive this thing is):

Launch video (live): Proton / DIRECTV 12 Launch
# D12 Launch-to-"Live" Expectations:
- It's expected that HD channels from D12 will be available 90-120 days after a successful launch.
- After launch and orbit raising maneuvers, DirecTV-12 will be located at 76 [no earlier than about 2/15/2010].
- After DirecTV-12 reaches 76, DirecTV will commence in-orbit testing of the satellite for approximately 4 weeks.
- After in-orbit testing is completed, DirecTV-12 will then be drifted to it's assigned location over the course of approximately 20 days [reaching that orbital position no later than about 5/5/2010].
What does it mean for subscribers?
D12 National / Continental US (CONUS) - Callsign S2797:
- 16 transponders (TP9-TP24) of national bandwidth for MPEG4 HD from 103
- Each transponder supporting 5 HD channels for a total capacity of 80 national HD channels
- Within the existing Ka-Hi (19890-20200 MHz) frequency range, supported with the current LNB
- Spaceway-1 (SW1) is currently allocated the entire Ka-Hi (19700-20200) frequency range, therefore it's expected that SW1 and D12 will now share the range, with SW1 using the lower end, and D12 using the higher end
D12 Local-in-Local (LiL):
- 10 transponders (TP15-TP24) of spot beam bandwidth for MPEG4 HD LiL from 103
- Supporting 49 spot beams
- Within the existing Ka-Lo (18600-18800 MHz) frequency range (same as D10), supported with the current LNB
- The spot beam bandwidth is for in-orbit redundancy or replacement for the spot beam capability of either D10 or D11 (if D12 were moved to 99)
D12 RB-2A ("BSS") - Callsign S2796:
- Named RB-2A for "BSS" payload on D12
- 18 transponders (TP1-TP18) of spot beam bandwidth for "niche services" from 103
- Supporting 4 spot beams to the "western U.S."
- Within the BSS (17345-17700 MHz) frequency range, with a new LNB expected/required
- This payload will allow DirecTV to begin providing commercial service in the 17/24 GHz BSS band before any other satellite operator in the world, making use of these valuable spectrum/orbital resources mere months after receiving its first license in the band.
