Anik reports that this Progress will fly on Soyuz-2.1a. That LV provides about 400 extra kg of payload - so how will this be accommodated on Progress? Perhaps the Rodnik tanks, the prop tanks and the cargo compartment will all simply be maxed out. In practice, that would be:
1300 kg dry cargo
420 kg water in Rodnik tanks
880 kg mid-section prop for ISS
250 kg PAO prop for use by ISS
That totals to 2850 kg, within 100 kg of the max capability of Soyuz-2.1a from Baikonur. A little more dry cargo could probably be stuffed into the cargo compartment.

Additional gas tanks like M-52, M-53, M-54 and M-55?

Yeah, I forgot about atmospheric gas tanks, that's good for 40 kg, and yes, external tanks could add a little more. No cargo compartment Rodnik tanks, though, since that decreases available cargo mass.

Maybe the rocket will be instrumented; for later manned missions, abort system tests?

Introduction of Soyuz-2 rocket for Progress launches does not mean that mass of cargoes will be increased. It means only that Roskosmos and TsSKB-Progress wants to replace Soyuz-U and Soyuz-FG rockets, because systems for them are producing in Ukraine and they are very old. RSC Energia categorically against introduction of Soyuz-2, because this rocket costs much money and does not give advantages for Progress and Soyuz launches.

Not so easy.
In order for the Soyuz 2-1a to maintain a trajectory so that lower stages drop into the drop zones, the payload mass must be some 400 kg more massive than for Soyuz-U (otherwise, the rocket will pass the drop zones by some tens of kilometers). An alternative would be to reprogram the flight computer to shut off the engines earlier than normal, but that would be risky - the optimal approach is appropriate loading of the system, not playing with software.
In the worst case, an extra 400 kg of prop and gases and water could be added to Progress that might be wasted at ISS, that is far cheaper than reprogramming the avionics. And yes, Progress can handle that additional mass during docking, as long as the c/g is maintained properly.
-
But adding 400kg would mean a redesign of Progress M-M, because in the present configuration the is no available space for more cargo.
At first, the use of Soyuz-2 was needed for Progress M1. But since this spacecraft is no longer in use, there is no more need for Soyuz-2.

Adding kgs of cargo not necessary implies additional space. It depends on the nature of these kgs... (density) :).

There is no requirement to redesign Progress-MM to incorporate 400 kg more cargo, all that is required is to fill the cargo compartment completely with dry cargo, fill all prop tanks, and all water and gas tanks, as described earlier in this thread.
Progress M-1 would allow even more cargo, by allowing an additional ~900 kg of prop in the refueling compartment.

You can bet that the UM will be filled with sufficient cargo, and that it itself will have sufficient mass, that the Soyuz-2 LV will drop stages almost exactly where Soyuz-U does.
But the question above is related to flying Progress to a higher initial orbit, and that cannot be done and still allow for stages to land in the appropriate drop zones.
However, the

The higher the initial orbit, the longer the rendezvous with ISS will take.

According to Anik, Progress M-22M is no longer flying on Soyuz 2-1A. but M-25M IS flying on the 2-1A.

Q This October we are expecting a maiden flight of cargo transportation vehicle Progress on top of Soyuz-2.1A LV. How many of those LVs is requested by Roscosmos for such missions?
A Currently we got a contract for manufacturing of 4 Soyuz-2.1A LV for cargo transportation vehicle Progress supply missions. We are planning to launch first vehicle till this year fall, 2 - next year, and one in 2016.
Q How many Progress vehicles would be launched on Soyuz-2.1A before this LV might be certified as a man-rated? When are you planning a maiden flight of manned Soyuz on Soyuz 2.1A?
A At present time the head think tank of [Russian aerospace] industry [TsNIIMash] is busy preparing program of qualifying flights and determining minimal number of launches required to confirm reliability of LV before commencing manned launches. Our formal proposals are submitted to TsNIIMash. We are proposing to perform 3 qualifying flights with Progress cargo vehicle and after that to launch a manned Soyuz on Soyuz 2.1 (fall 2016 or in beginning of 2017).
He also mentioned that Centre is NOT planning to use Soyuz 2.1b LV for manned launches of Soyuz-TMA spacecrafts and Progess Cargo transportation vehicles.

It is not planning for now.

So there is only one contract for four rockets at the moment.
The tender for four 2-1A rockets was raised in July 2012, contract signed August 2012.
1st delivery was scheduled for June 2014, for the launch of Progress-MS № 432, scheduled for launch in October 2014.
http://www.zakupki.gov.ru/pgz/public/action/orders/info/events_journal/show?notificationId=3885879
So any earlier possible use of 2-1A is incorrect?

Yes. You can do us a favor and calculate the increased cost of using 2-1A vs Soyuz-U for Progress, to see if there is a significant difference. We could then figure out the launch cost of flying the additional 400 kg of payload.

In an earlier post, I mentioned that if the Progress for this mission is not loaded with an extra 400 kg of cargo, that the launch vehicle may have trouble with the stages not hitting the standard drop zones for Progress launches (due to the extra capacity of the Soyuz 2-1a LV.
What I didn't mention is that if the Progress does not carry additional cargo, the upper stage could be ballasted to make sure that the LV trajectory is nominal for a Progress mission.
My opinion is that this Progress will be loaded with 2900 kg of cargo.

One unknown is the type of fairing.
The tender for transportation of the rocket to the launch site, unlike those for Soyuz-U, does not specify.

The fairing should be the standard Progress fairing, since there is a requirement for late loading of cargo, and the Progress technical hatches should be available for specialists after the fairing is in place.

Energia info is out of date at this time. Originally this flight was on Soyuz-U but the Soyuz-U was already flown a few missions ago due to remaining manned certification tasks and ROSCOSMOS approvals. These flights do not require Fregat and as result was cleared to proceed with the flight following conclusion of the Soyuz-2 series investigation.

Different from the Apollo lunar module? :-)
Different from an ISS module?
and many science fiction spaceships cannot enter atmosphere...
I would say there is an interesting category of 'spacecraft with pressurized volume that can be entered on orbit
by astronauts'... Progress and the ISS modules are the same in this respect - I think 'spaceship' is a reasonable
word for this category, but YMMV.

One could see that the introduction of upgraded control systems greatly improved the orbit injection accuracy in the Soyuz series:
For Progress M-25M the orbit specifications are:
Inclination: 51.67 ± 0.03 °
Perigee: 193 ± 2 km
Apogee: 240 ± 5 km
Period: 88.53 ± 0.05 min
....compared with that of Progress M-24M:
Inclination: 51.66 ± 0.06 °
Perigee: 193 + 7 / -15 km
Apogee: 245 ± 42 km
Period: 88.59 ± 0.37 min
Also notice that there are some differences in the launch sequence as well - notably that the fairing separates much later on the Soyuz-2 (T+296.35s instead of T+160.56s on the Soyuz-U, i.e. now after 2nd stage has separated!). I think this is because separating later is actually preferable, but due to the limited control ability on the older series the fairing had to be shaved earlier in flight? ::)
-
One of the best Progress threads, lots of good info here. Many thanks!

I doubt it - if anything presence of fairing makes control easier.

This also could be the way that Soyuz 2 maintains the same drop zone for the core stage as for Soyu-U, by carrying the fairing longer.

Contact and Capture.
-
Eight minutes past the hour, a minute ahead of schedule, 5hrs 59mins after launch.
-
Seems like more post-contact motion than usual.
Damped out well.
-
Welcome to the station! Progress is still holding the title for being the best choice for space logistics vehicles of last resort right now. :D
-
Couple more pre docking views. (sorry for the ham fisted capping)

Does it have to do a set number of Progress launches successfully before it starts being used for Soyuz?
4.
One today, two more in 2015, and one in 2016.

Thank you. Is 2016 when the first Soyuz launch will be made with it.

First manned launch using Soyuz-2.1a will be Soyuz MS-4, scheduled on 30th March 2017.

According to this site, the total cargo mass carried by the vehicle was 2322 kg.
Since this is more or less the same as cargo mass for Progress when launched by the less capable Soyuz-U, it seems that the launch trajectory maintained the usual drop zones by the expedient of carrying the payload fairing for a longer period (at 296 seconds into flight vs the normal 160 seconds).
According to TsUP, the boosters landed 355 km downrange vs 348 km for Soyuz-U.
The payload fairing landed 1550 km downrange rather than 527 km.
The core stage landed 1576 km downrange rather than 1570 km for Soyuz-U.
Because of the greater precision in the orbital insertion, due the digital control system in Soyuz 2, the first two orbital maneuvers were half the size of those normally conducted. The savings in delta-V was about 40 meters per second, which is about 20 kg of propellant use.

You see how routine this ISS logistics flight is (compared with, say, the one that flew hours before this one :-X) when you need to reach page 7 to dig out this thread!
Anyway this Progress will leave the station in 2 hours time at around 06:40 UTC. ;)

You see, this has become so routine that no-one here managed to catch this one (even in this sleepy hours had this be a Dragon leaving I'm sure there will be people posting ::))

I have hit one of those things I am struggling to understand. It looks like they under insured this launch?
Progress M-25M (№424) flew on Soyuz-2-1a №Г15000-021 (16М136С). That rocket had been manufactured under contract №353-1193/12, and had been intended to launch Progress MS-02 (№432) [source (http://www.zakupki.gov.ru/epz/contract/contractCard/common-info.html?reestrNumber=0173100007012000255)]. Total cost 939,502,000 Russian ruble.
A Soyuz-U had been ordered for Progress-M №424, under contract №353-1130/12 [source (http://www.zakupki.gov.ru/epz/contract/contractCard/common-info.html?reestrNumber=0173100007012000181)]. Total cost 636,570,000 Russian ruble.
The launch was insured:-
Страхование рисков при запуске ракеты-носителя «Союз-2.1а» с космическим аппаратом «Прогресс М-25М» (№424) и стыковке космического аппарата «Прогресс М-25М» с Международной космической станцией.
[source (http://www.zakupki.gov.ru/223/purchase/public/purchase/info/common-info.html?noticeId=1590508)]
Those tenders for insurance are a little confusing because they round things up, but the rocket and fairing are shown to have cost 684 million ruble. That would cover a Soyuz-U rocket at 636,570,000 and 46,686,000 for the fairing; not a Soyuz-2-1a.
Lucky then it was a success?

I think it's not unusual to slightly underinsure an item (launch, valuables, etc) to save a little on the premium. It's equivalent to insuring the rest of the value yourself: it's your loss if something goes wrong. An instance company likes this, for the same reason they *don't* like overinsuring: they want to make sure your incentives are aligned toward success.
So the insurance value is (in the absence of corruption) probably best treated as a lower limit on the value of the item insured.
This is just a general observation from economics; I have no special insight on Russian launch insurance. (And my observations are in the absence of market distortions or corruption, which are probably not sound presuppositions in this case.)

He also mentioned that Centre is NOT planning to use Soyuz 2.1b LV for manned launches of Soyuz-TMA spacecrafts and Progess Cargo transportation vehicles
It is not planning for now.
