Thanks Stan! I hope you don't mind me starting a thread on this launch.

Уже не совсем так. С 23-го апреля Intelsat сдвигается как минимум на 17-е мая, а то и на июнь. А Echostar на август - сентябрь.

Anatoly's web site has this note on the Intelsat-31 launch page:
Quote
Investigation into the close call launch begins

Following the successful release of the Intelsat-31 satellite, Russia formed an accident commission to investigate the circumstances of a close call during the operation of the second stage's propulsion system and to develop corrective actions as necessary, industry sources said.

(Details to come)

Confirmation that investigation is occurring and ongoing:
Investigation into upper stage glitch delays next Proton launch

Also, the investigation is the reason for the substantial delay of this, the next Proton/ILS launch, from August 29 to October 10.

From Via Satellite (new name for Satellite Today?), dated September 22, 2016:
EchoStar Prepares for Q4 Satellite Launch, Makes OTT Investment
Quote
Space Systems Loral (SSL) has certified the EchoStar 21 satellite ready to ship ahead of a fourth quarter 2016 launch. The communications satellite — to be located at 10.25 degrees east — was intended for launch in April 2016, but was placed in storage after the delay of its May 2016 Proton launch. SSL has now completed final shipment preparations at its Palo Alto, California facility, where the spacecraft will remain in storage until EchoStar receives notification of launch vehicle availability.

Primary source--EchoStar press release:
EchoStar XXI Satellite Completes Final Preparations for Shipment
Quote
ENGLEWOOD, Colo., Sept. 22, 2016—EchoStar Corporation (NASDAQ: SATS) announced today that the EchoStar XXI satellite―to be located at 10.25° East―has been certified “ready to ship” by spacecraft manufacturer Space Systems Loral (SSL).

EchoStar subsidiary EchoStar Mobile Limited (EML) will utilize a portion of EchoStar XXI’s capacity to provide commercial communications wholesalers with an advanced network for reliable, IP-based mobile satellite services (MSS) for voice and narrowband data services in Europe. EML is an EU-wide licensee authorized to provide an integrated MSS network with a complementary ground component. The company has provided notice of the completion of construction and temporary storage of EchoStar XXI to relevant European Union and member state regulators.

SSL had previously completed pre-shipment procedures for EchoStar XXI in April 2016, but the satellite was placed in storage after EchoStar received notification that the launch had been postponed from its original launch slot of May 2016. In anticipation of launch in the fourth quarter of 2016, SSL has completed final shipment preparations at their facility in Palo Alto, California, where the spacecraft will remain in storage until EchoStar receives notification of launch vehicle availability.

"We are pleased to have completed final preparations of the EchoStar XXI spacecraft and look forward to its launch in the fourth quarter,” said Derek de Bastos, chief technology officer for EchoStar Satellite Services.

And, regarding the Proton launch schedule:
According to Anatoly Zak, http://russianspaceweb.com/proton_2016.html#10 , the launch of Blagovest will only take place in January or February 2017 and the launch of EchoStar-XXI was delayed to December 2016.

This satellite appears to have followed a torturous, slightly-over-a-decade-long path from order to launch: TerreStar Networks, etc.

I look forward to its NSF launch article!  :)

Searching around the ILS web site, I found this web page here:
http://www.ilslaunch.com/node/4713

From there, I found a draft mission overview here, dated November 15:
http://www.ilslaunch.com/sites/default/files/pdf/EchoStarXXI-MO-DRAFT.pdf

The launch schedule thread has this mission launching December 22.

I'll be interested to hear about the conclusions of the commission investigating the performance shortfall of the previous Proton launch's second stage and the actions to fix the issue.

Also, I'm wondering when the satellite will be delivered to Baikonur.

The following is brief summary:
Breez-M is currently in final processing. ILS has begun preparations for SC fueling and irreversible operations which will occur in the near future. Launch date will remain NET December 2016 until State commission gives green light for RTF.

I have also seen schedules online that have launch date as NET 28 December till NLT 31 December 2016 and launch is from 81/24.

Launch of Proton rocket carrying US satellite postponed till Dec 28
http://tass.com/science/920080

MOSCOW, December 16. /TASS/. The launch of the US space satellite EchoStar-21 with Russia’s Proton rocket has been postponed again from December 22 to December 28, a source in the space rocket industry has told TASS.
"The newly-set date and time are December 28, 19:26 Moscow time," the source said without mentioning any reason why the launch has put off.
The Russian space corporation Roscosmos has refrained from comment.
Originally, the satellite was to be put in space in the first quarter of this year. The launch was postponed five times.
EchoStar-21 (previously named EchoStar T2 and TerreStar 2), manufactured by Space Systems/Loral is expected to provide communication services in Europe. Once in orbit, it will be included in Britain’s national register.
The previous launch of a Proton rocket was on June 9. It put in space the Intelsat 31 satellite.

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.

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?

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.

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?

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?

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?

I'm unable to answer that question for a particular spacecraft however Jim and others can provide insight on the general average for comsats.

Anatoly Zak reporting major quality control issues (replacement of heat-resistant alloys with lower-quality ones in key engine parts) as being a possible contributing factor to Proton's and Soyuz's woes:

Linked to Phase IV improvements or just irregular practice?

Have they already figured out why the second stage shut down early during Intelsat 31/DLA-2?

I'm wondering if that's another reason of the long delay besides the first stage swap.

Searching around the ILS web site, I found this web page here:
http://www.ilslaunch.com/node/4713

From there, I found a draft mission overview here, dated November 15:
http://www.ilslaunch.com/sites/default/files/pdf/EchoStarXXI-MO-DRAFT.pdf

The launch schedule thread has this mission launching December 22.

I'll be interested to hear about the conclusions of the commission investigating the performance shortfall of the previous Proton launch's second stage and the actions to fix the issue.

Also, I'm wondering when the satellite will be delivered to Baikonur.


It has now been updated. The ‘satellite mission’ section was blank in the draft version.

Another revision, with mass now 6,900 kg.

Interfax news seems to place the launch into a late may-june target!

Russia’s Proton-M carrier rocket first launch scheduled for May

MOSCOW, March 31. /TASS/. The first launch of Russia’s Proton-M carrier rocket this year is scheduled for the end of May, Chief Designer for Launch Vehicles and Ground Infrastructure Alexander Medvedev said on Friday.
"The first launch is planned for the end of May," the chief designer said.

The launch of an EchoStar 21 spacecraft was planned back last year but was delayed over problems found in the engines of a Proton-M carrier rocket.

A total of seven Proton carrier rocket launches are planned until the end of this year under the federal space program and in the interests of commercial customers.

Russia’s State Space Corporation Roscosmos earlier recalled for tests all the engines mounted on the second and the third stages of Proton-M carrier rockets and produced at the Voronezh Mechanical Factory.
According to Roscosmos, a more expensive solder failing to meet the requirements specification was used by the factory as part of the engine production.

Roscosmos also gave instructions to replace the engines produced by this factory and mounted on the third stages of Soyuz-U and Soyuz-FG carrier rockets intended for launches to the International Space Station. The engines had to be replaced after an accident with a Soyuz-U carrier rocket on December 1, 2016, which resulted in the crash of a Progress MS-04 space freighter.

After Roscosmos officials visited the Voronezh Mechanical Factory on January 20, Factory Director Ivan Koptev resigned of his own free will over the unsatisfactory work and quality of the enterprise’s output.

NEW YORK, April 5. /TASS/. The next launch of the Proton-M carrier rocket is scheduled to take place on May 29, Roscosmos spokesman Igor Burenkov told TASS by phone from Colorado Springs, where he is taking part in a space conference.

"The works proceed according to the schedule," he said. ‘We plan to carry out the first launch of Proton on May 29, to put a US satellite into orbit."

Commenting on the recall of the Proton engines, the official described it as an "unprecedented matter."
"We stick to the policy of transparency," he said. "It’s not about certain flaws found in those engines. We simply had some concerns that some of them may be flawed," he said.

The Russian version of the TASS report says a total of seven Proton launches are planned for this year, both for Roscosmos and for commercial customers.

I note that they say "May 29" without specifying the year ..............
