Where it's Warm
Echostar 5 has started on it's journey to 148W. New TLE this morning shows it about 30 km above geostationary (moving west). It will probably move to 100 km or more above geostationary in the next few days and accelerate it's movement west.

Moved up to 55 km above geostationary and moving west at about 0.7 degrees/day.

Looks like it has been stable for a couple of days, moving at 0.7 degrees/day. Arrival at 148w in 3 weeks so ( 131.4W now). So we can can expect to see E1 make it's transfer and start it's move to 77W in early June.

If the June 2009 estimate for end of life for E*5 (again not mentioned in the STA request) turns out to be accurate, will Dish try for a 4th extension? Will everyone's channels be available from other slots by the time there's no functional bird left at 148°?

It will soon be pushing a year from the E2 failure date and they will have sucessfully kept the license intact with no satellite serving those 16 licensed transponders . It would not suprise me if the real reason E5 did not move off 129W when Ciel 2 arrived was that they were using "software problems" as an excuse and were intentionally eating up time with extensions.

My guess is that the musical chairs will continue with E5 "slotkeeping" until Nimiq 5 launches in late summer. Then, E6 could move to 61.5W and E3 could move to 148W and be the "slotkeeper" with E5 deorbited.

148W is a good slot and can provide great service for a large part of Conus - as far east as the Mississipi (not many mountains in that area of the country). They claim in their submissions that a "new" satellite will be build for 148W.
 
From the financials;

Looks like it would fit well in a Mad Max movie.

EchoStar V. EchoStar V was originally designed with a minimum 12-year design life. Momentum wheel failures in prior years, together with relocation of the satellite between orbital locations, resulted in increased fuel consumption, as previously disclosed. Prior to 2009, EchoStar V experienced anomalies resulting in the loss of 13 solar array strings. During April 2009, EchoStar V lost an additional solar array string. These issues have not impacted commercial operation of the satellite. However, during 2005, as a result of the momentum wheel failures

I do not really see E3 moving to 148. E3 was built for 61.5, it would probably hit China at 148... I know they can point it at the US, but it would be a very bad footprint. I see it staying at 61.5 for a backup for a while. EA is much more important than 148.

One or more BSS satellites have to go there or they will lose the BSS license(s). They have informed FCC they are going to maintain the permits active. They have to put something(s) there that will cover the full spectrum
