Anatoly's web site has this note on the Intelsat-31 launch page (http://russianspaceweb.com/intelsat-31.html#investigation):
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 (https://spaceflightnow.com/2016/08/01/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.

EchoStar Prepares for Q4 Satellite Launch, Makes OTT Investment (http://www.satellitetoday.com/publications/st/2016/09/22/echostar-prepares-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 (http://www.echostar.com/NewsEvents/PressReleases/PressRelease.aspx?prid=31462)
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:

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.

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.

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?

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?

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.

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.

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.

Hmm.......looking at posts from people involved in the Proton on NK it seems that the May 29 date was already long out of of the window as the team is slow to pick up work - current pointers are at around June 6-15 but even that might not stick.  ::)

The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 24 at the Baikonur Cosmodrome in Kazakhstan, with the  EchoStar XXI satellite on board. The first three stages
of the Proton will use a standard ascent profile to place the orbital unit (Breeze M upper stage and the
EchoStar XXI satellite) into a sub-orbital trajectory.
From this point in the mission, the Breeze M will  perform planned mission maneuvers to advance the
orbital unit first to a nearly circular parking orbit, then to an intermediate orbit, followed by a transfer
orbit, and finally to a geosynchronous transfer orbit.
Separation of the EchoStar XXI satellite is scheduled to occur approximately 9 hours, 13 minutes after liftoff.

Tomorrow's launch will end the longest gap between two launches in Proton's history, less than four hours short of 364 days. A 24-hour scrub and it would be a year to the day since Proton's last flight.

Although it was designed as a missile, UR-500 never flew suborbitally - aside from a failed orbital launch attempt. The only (intentional) suborbital Proton launch was a Proton-K in 1970, launched as a test flight after the rocket had scored nine failures in its eleven previous launches.

The longest gap previously was between the final UR-500 and the first Proton-K, 247 days apart.

It appears this is a Phase IV Proton variant according to posts up thread. Does anyone know what improvements were made? I've always been impressed at how the Proton just looks so grunty.
The article doesn't mention the upgrades. I was wondering with the shear mass of this payload and the fact the launch is using the latest Proton upgrades, perhaps the fixes that came out of the accident investigation may have incurred a slight performance loss which could have contributed to the delay? Happy to be shot down on this

Congratulations to Echostar for finally getting their bird in orbit, and especially to Khrunichev and Voronezh for -apparently- ironing out some entrenched goblins in their vehicles with a (very) long-awaited successful return to flight!

It appears this is a Phase IV Proton variant according to posts up thread. Does anyone know what improvements were made? I've always been impressed at how the Proton just looks so grunty.
The article doesn't mention the upgrades. I was wondering with the shear mass of this payload and the fact the launch is using the latest Proton upgrades, perhaps the fixes that came out of the accident investigation may have incurred a slight performance loss which could have contributed to the delay? Happy to be shot down on this

According to SpaceFlight101's article on Intelsat 31's launch:

Quote
The Phase IV Proton uses a composite second stage forward bay, new five-axis milling techniques to reduce tolerances on the second stage and decrease the overall mass of the launcher. The third stage switched the metal alloy from which its tanks are manufactured and also features a composite instrument bay. Modifications of the Briz-M include weight reduction on the Telemetry System and an improved composite overwrapped pressure vessel tank design in the high-pressure section of the propulsion system. The Phase IV payload fairing uses optimized composite shell technology.


These changes are unrelated to the engine failure on last year's flight, so it's unlikely Phase IV upgrades and the quality control fixes (mainly related to the replacement of the solder joints in the gas generators) are related, even if the latter ones have meant performance losses (which they shouldn't have by themselves).

ILS PROTON SUCCESSFULLY LAUNCHES THE ECHOSTAR XXI SATELLITE: Heaviest Satellite Launched on Proton Breeze M; 94th Proton Breeze M Mission

BAIKONUR COSMODROME, Kazakhstan, June 8, 2017 – International Launch Services (ILS), a leading launch services provider for the global commercial satellite industry, successfully delivered the EchoStar XXI satellite into orbit today on an ILS Proton for EchoStar Corporation (NASDAQ: SATS). EchoStar is a premier global provider of satellite communication solutions headquartered in Englewood, Colorado.

The ILS Proton launched from Pad 24 within the Baikonur Cosmodrome at 9:45 AM local time today (03:45 GMT, 11:45 PM ET on June 7) with the EchoStar XXI satellite on board. The first three stages of the Proton Breeze M utilized a standard ascent profile to place the orbital unit (Breeze M upper stage and the EchoStar XXI satellite) into a suborbital trajectory. Then, the Breeze M performed planned mission maneuvers to advance the orbital unit first to a nearly circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, then finally to a geosynchronous transfer orbit. Separation of the EchoStar XXI satellite occurred at approximately 9 hours and 13 minutes after lift-off.

This was the 413th launch for Proton since the inaugural flight in July 1965, and the 94th ILS Proton launch executed. The Proton Breeze M launch vehicle was developed and built by Khrunichev Space Center of Moscow, one of the pillars of the Russian Space industry and majority shareholder in ILS. EchoStar XXI, weighing nearly 9 metric tons, is the heaviest satellite launched by ILS Proton to date.

EchoStar XXI was manufactured by SSL utilizing their space-proven 1300 platform. EchoStar XXI is a state-of-the-art S-band satellite designed to provide mobile connectivity throughout Europe to be located at the 10.25° East orbital slot. EchoStar subsidiary EchoStar Mobile Limited, an EU-wide licensee for an integrated mobile satellite service network with a complementary ground component, will utilize a portion of the capacity on EchoStar XXI to provision its next-generation, all IP-enabled mobile communications network. This 29th SSL satellite launched on Proton also features a large unfurlable reflector to provide the high performance levels required for mobile services.

“We have been honored to have served EchoStar for nearly 20 years now, dating back to the launch of the EchoStar IV satellite on Proton in 1998. The ILS team is very proud to have played a role in the expansion of the EchoStar satellite fleet and enabling connectivity across Europe, with the successful launch of EchoStar XXI. Our sincere thanks to all of the EchoStar XXI team members who played a vital role in the success of this mission,” said Kirk Pysher, President of ILS.”

"The launch of EchoStar XXI is a major milestone in the continued expansion of our satellite fleet," said Anders Johnson, executive director of EchoStar Mobile and president of EchoStar Satellite Services L.L.C. "EchoStar XXI will provide capacity to EchoStar Mobile for commercial wholesalers with a new, advanced network for reliable, IP-based MSS voice and data services in Europe. We appreciate the hard work and dedication of all of the team members from EchoStar, SSL, ILS and Khrunichev, who played a role in the successful launch of EchoStar XXI.”
