Geez; this launch keeps getting delayed and delayed. I understand what the recent problem was, but it frustrates me that it's been six months since EchoStar 21's original date on June 25.

So when was the last time there were 3 or less Proton launches in a calendar year?  ::)

Spaceflight Now published their article relating to EchoStar 21's delay into next year.

From the "Plan of Russian Space Launches (part 2)" thread:
Launch
*EchoStar-XXI - Proton-M/Briz-M (93702/99571) - Baikonur, 81/24*
- was delayed again per forum NK:
http://novosti-kosmonavtiki.ru/forum/messages/forum14/topic14042/message1607830/#message1607830
The new dates are Feb-6 to Feb-12

***
Also, I'm unclear about the 1st stage repairs for this flight.  Are the repairs being done at Baikonur, or has the first stage been returned to its manufacturer for repair?

Returned to Moscow for repair?
The launch has now slipped into NET January (with one of the Proton stages apparently requiring transport back to the Moscow plant for repairs!): http://www.roscosmos.ru/23073/

Where is an information about stage's return to Moscow and about launch in NET January in Roskosmos press-release?

Whoops, I saw that the official release only mentioned a delay; it was Anatoly Zak who reported that based on posts on your forum.  ;)

Repaired at Baikonur?
Anatoly Zak RussianSpaceWeb says here, as of this posting:
Quote
By December 23, the satellite had already been integrated with the launch vehicle, when an unspecified technical problem in the first stage of the rocket, discovered around a week before the planned liftoff, forced to postpone the mission until January 2017, at the earliest. According to industry sources, a failed component would be replaced at the launch site.

Was there an edit/correction on RussianSpaceWeb.com between 12/23 and 1/22?

***
Finally, if I'm understanding everything correctly, this launcher has had/is having/will have corrective actions and/or repairs on BOTH the 1st (unspecified technical issues) and 2nd (corrective actions after the Intelsat 31 incident) stages?

To add If problem cannot be resolved the first stage will be swapped with another assembled one.

Ouch!
Are there any Proton first stages available for swapping at Baikonur, or will one have to be shipped in?

(With the delays after the Intelsat 31 incident with the 2nd stage, I wonder if 1st stage production would continue unabated, followed by shipment of said 1st stages to Baikonur.)

Given the satellite mass from Gunter's Space Page, almost 6900 kg, and a GTO delivery, I conclude this launch must have a Phase IV Proton-M/Briz-M launcher.  There may not be any "spares" of this newest phase at hand?

To follow further, what is the "phase" of other, possibly available Proton-M's?  Phase III?  And which phase will the upcoming Blok DM-03 upper stage launches use?

According to Interfax launch could be delayed by several months...

Online ZachS09

Even if this delay won't stop, will EchoStar still want EchoStar 21 to be launched atop Proton?

I ask that because they tend to change launch vehicles if the delay is too much. What if they ask ULA to use one of their Atlas Vs in the near future?

Its possible, but it becomes more difficult to transport a previously fueled spacecraft as some cargo airlines do not allow spacecraft matching those circumstances or it become costly and restrictive to do so.

Remind me: how long has EchoStar 21 been fueled?

This is now the second-longest time between launches in Proton's history.

The current record is just under 247 days, between the final UR-500 (the original two-stage Proton) on 6 July 1966, and the maiden flight of the Proton-K on 10 March 1967. Proton has until 11 February to launch if it is not to surpass this.

I understand that the hydrazine monopropellants are storable, meaning it can stay in the tanks for many years, but just in case of corrosion, how long will it be until they empty the tanks?
