Falcon 9: ABS-SatMex (dual Boeing commsats)


Recommended Posts

ABS-SatMex, aka ABS-3A/Eutelsat 115 West B

Static fire: NET Feb. 22, 2015

Launch: NET Feb 27, 2015

Window: 2301-2346 Local (Eastern)

Launch may slip right into early March. May not.

Satellites: 2 Boeing 702SP commsats. The 702SP is a new commsat, these are the first, which uses no chemical propulsion - just electric Hall Effect thrusters and a much smaller quantity of xenon as a reaction mass. This drastically reduces the mass of the 702SP, allowing them to be launched in pairs (dual manifesting) on launchers smaller than Proton or Ariane 5.

As the bottom pic shows, they're lighter but not really "small."

Also, there will be no recovery attempts made (at least, no ASDS involved) on this launch. The combined weight of these two sats require everything the F9 has got, that is why a launch like this would in the future preferably be done by the Falcon Heavy so that all cores can be recovered.

 

I think they will also leave out stuff like grid fins and landing legs, but i am not 100% sure. Maybe DocM can confirm.

  • 2 weeks later...

Static fire tomorrow (Tuesday), one day later than expected. Launch may slip to match.

All else sounding good.

Like SES-8, this will be a launch to a supersynhronous transfer orbit. This usually means a perigee of about 300 km and an apogee of about 80,000 to 90,000 km. Exact target parameters when they come in.

Considering just the engine bay has at bc least 27 CPU's and each of the 2 avionics systems are triple-string, you and most of your friends could probably play Crysis on an F9 ;)

Static fire moved to tomorrow,

Our History Center will be closed tomorrow, Wednesday February 25th for SpaceX operations- sorry for the short notice and thanks for understanding!

T-14 and all's well.

Polling for terminal count.

ALL are GO.

Telemetry station Bermuda is having problems so we may not see S2 shutdown.

T-9:30

Valves open, chilling in the engines.
