Russia to Introduce Two-Orbit Express Rendezvous with International Space Station
October 6, 2017

Russia plans to speed up the rendezvous of the country's Soyuz and Progress spacecraft to bring crews and cargo to the International Space Station faster than with the current six-hour flight profile that has been in use for the last five years. The upcoming Progress MS-07 cargo resupply mission will debut a new two-orbit rendezvous profile, taking only three and a half hours fr om liftoff to docking with crewed missions inaugurating the new rendezvous technique once proven by Progress.

For decades, crews on Russia's Soyuz and the U.S. Space Shuttle typically flew for two days before reaching their orbital destination. The introduction of the four-orbit, six-hour rendezvous in 2012 brought the major benefit of allowing crews to trade the cramped quarters of their Soyuz spacecraft with the comforts of the International Space Station in a matter of hours instead of spending two nights aboard the Soyuz spacecraft as it linked up with ISS over the course of 34 orbits.

However, fast-track rendezvous maneuvers are nothing new from a historical point of view as many of the early missions in programs Gemini and Soyuz utilized quick rendezvous schemes through a direct ascent profile. Fast maneuvers in those days were accomplished by launching a target vehicle into a specially designed orbit that allowed a chaser to be deployed into the orbital plane of the target at a small angular distance between the two.

The early rendezvous and docking demonstrations in the U.S. Space Program were during Project Gemini with the first rendezvous occurring between the Gemini 7 and Gemini 6A spacecraft that launched eleven days into the long-duration mission of Gemini 7, meeting up six hours after the chasing spacecraft had lifted off from Florida for over five hours of formation flying.

Later docking demonstration missions between crewed Gemini spacecraft and unmanned Agena Target Vehicles launched the Agena when the crew of Gemini was already sitting aboard their spacecraft, ready to be lifted into orbit after the Agena completed one revolution of Earth. To date, Gemini 11 holds the record for the fastest crewed rendezvous, docking with its Agena Target Vehicle 94 minutes after liftoff.

The record for the fastest docking overall belongs to the Russians: in 1968, Kosmos-213 – an uncrewed version of the Soyuz spacecraft – linked up with Kosmos-212, another uncrewed Soyuz, just 47 minutes after lifting off, 38 minutes after achieving orbit. Soyuz 3, piloted by Georgy Beregovoy managed to reach its target, the Soyuz 2 launched the day before, less than one hour after taking off but had to abort the docking at 200 meters distance.

After the space race reached its culmination and  man walked on the Moon came the era of orbiting space stations. Given the requirements of long-term operation of orbiting stations, direct ascent was no longer a possibility as the orbit of the stations could not be tuned in a precise-enough manner to set up the strict phasing requirements for such a maneuver.

Instead, the U.S. developed an eight-hour rendezvous used by the crewed Skylab missions while the Russians ferried its Soyuz crews to the Salyut space stations on day-long flights before extending the rendezvous to 34 orbits, taking just over two days when Mir began operations in 1986 as there was a desire to reduce phasing maneuvers completed by the station to facilitate one-day rendezvous missions. The two-day rendezvous was retained for Soyuz and Progress missions to the International Space Station and the U.S. Space Shuttles also made use of a two-day trajectory profile when linking up with Mir or ISS.

To get a spacecraft to its orbital destination, attention has to be paid to two essential parameters: the planar separation between the chaser's injection orbit and its target, and the phase angle between the two spacecraft as they begin their rendezvous.

Typically, for a mission aiming for a specific destination, launch must occur in the brief moment when Earth's rotation carries the launch site into the target spacecraft's orbital plane. If launch occurs at any other time, the resulting orbit will cross the target orbit plane at too steep an angle for the chaser to correct with its limited propellant supply.

Planar launch windows oftentimes are instantaneous, though some vehicles like the Space Shuttle and Atlas V as a current example, were able to stretch the planar windows through their ability to yaw-steer during ascent, essentially bending their flight path to steer from an out-of-plane liftoff into the target plane (of course coming at the cost of extra propellants).

The second constraint upon rendezvous maneuvers is the phase angle between the chaser and its target at the moment of orbital insertion. The phase angle refers to the angular separation of the spacecraft and target along the same orbital track and can be taken as a measure of the distance the chaser has to 'catch up' in order to reach the target.

Launching into a lower orbit than the target, the chaser has a shorter orbital period and thus catches up over time. At the precise moment the orbital plane of the target is carried through the launch site, the target could be anywhere along its orbit around the Earth if no advance preparations are made by the target vehicle to be in a specific position in its orbit at the planar launch time.

A two-day approach allows for a number of options in terms of relative maneuvering to allow the chaser to catch up with its target. In fact, Soyuz had a broad phasing range of 150 degrees when taking its two-day trip to the Space Station. But when time is of the essence in a fast-track rendezvous scheme, the phase angle could not exceed 35 degrees as Soyuz only has a limited ability to catch up – requiring the Station to be leading the spacecraft at orbital insertion by no more than 3,500 Kilometers.


Soyuz/Progress Approach Scenarios from 30° Phase – Image: RSC Energia

Waiting for the right geometry to naturally occur as the target's orbit progresses could mean weeks would pass in between favorable launch slots. Therefore, the phase angle is carefully controlled via small maneuvers by the target vehicle that slightly alter its orbit in order to place it in the right spot at the right time. These maneuvers, if performed close to the chaser's launch date, will be quite significant as large changes could be needed to set up the proper phase, but if performed over the course of several weeks with proper planning of the orbital progression, these phasing maneuvers can be a small as one meter per second and double as orbital maintenance maneuvers to counter drag in the upper reaches of the atmosphere.

Development of the four-orbit rendezvous technique was initiated by Soyuz manufacturer RSC Energia and the trajectory department of the Russian Mission Control Center as an object of study before 2010.

Getting crews to their destination faster was viewed to have great benefits – first and foremost reducing the time spent in the cramped Soyuz but also looking at human factors as microgravity-induced discomfort for most crew members only sets in after the first six or seven orbits while the first hours of the flight are usually dominated by an exhilarated feeling of having finally arrived in space after years of training. Completing the rendezvous within this window of peak alertness and dealing with initial side effects of space travel like nausea and fatigue in the comforts of ISS was deemed beneficial from a crew standpoint.

A positive effect on the technology side was that the fast rendezvous scheme came with a reduction of propellant consumption on the Progress/Soyuz spacecraft. The fuel expenditure to reach the Space Station's orbit remains the same between the two-day and six-hour rendezvous but the fuel spent on controlling the spacecraft's orientation is reduced by some 20 Kilograms by eliminating the need for two days of attitude control.


4-Orbit Profile – Image: RSC Energia

To achieve a four-orbit link-up, designers switched from 'measure first, fire second' to 'fire first, measure second' – i.e. instead of spending an entire orbit in the injection orbit for measurements of the initial orbit parameters before making orbit-raising maneuvers, the new rendezvous calls for initial maneuvers to be completed on the first lap around Earth based on the planned orbital injection parameters. Measurements of the actual parameters taken after injection are extrapolated with the pre-planned burns and correction maneuvers are designed to take place on the second orbit of the mission to position the spacecraft for the initiation of the Automated Rendezvous Sequence on Orbit #3.

The actual final rendezvous phase in which Soyuz/Progress links up from a distance of 200 Kilometers through the use of its radio-based navigation system remained unchanged at ~100 minutes from the 34-orbit profile as flight designers did not want to touch a well-proven method.


Soyuz TMA-08M – Photo: NASA

The Russian space program has the luxury of operating cargo and crew spacecraft that are of very similar design, thus allowing the cargo vehicle to act as a pathfinder whenever new technologies or techniques are introduced in order to reduce risk for the crewed Soyuz. The nuts and bolts of the four-orbit rendezvous were proven through a series of demonstrations involving Progress, the first occurring on the Progress M-16M mission in August 2012. Two subsequent Progress missions in 2012 and 13 also succeeded in reaching ISS after four orbits, clearing the new rendezvous to be used on crewed flights.

The Soyuz TMA-08M crew of Pavel Vinogradov, Aleksandr Misurkin and Chris Cassidy became the first to make a same-day launch-and-docking in March 2013. The next three Soyuz missions also went without a hitch and Soyuz TMA-12M was well on its way to ISS when it ran into trouble on its first Orbit #2 correction maneuver due to a flight software issue that placed the craft into an incorrect orientation. The mission demonstrated the safe abort from an express rendezvous to a two-day profile and made a safe docking to ISS after taking the scenic route.


3/4-Orbit Approach Types – Image: RSC Energia

Since its inauguration, the fast rendezvous profile has been the preferred method for Progress and Soyuz to fly to the International Space Station, though a number of exceptions have been made when orbital geometry was unfavorable due to schedule changes or when the MS-series of Progress & Soyuz was inaugurated with a series of two-day flights.

At the time the four-orbit profile was put in practice, work was already underway to further speed up future trips to ISS. A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper lim it of 30-35° to 25-28°.


Two-Orbit Rendezvous Profile – Image: RSC Energia/TSNIIMASH "Cosmonautics & Rocket Engineering"

To realize a two-orbit launch-to-docking profile, one would either have to deal with a very narrow phase angle range or take a different approach to find a compromise between planar and phase angle constraints. The method chosen by the Russian flight dynamics team is referred to as a Quasi-Coplanar Insertion and will broaden the planar launch window and so allow the chaser to be launched into an orbit with optimized phase angle while keeping the planar separation within a manageable range.

The second important trick that comes into play is a change in orbital inclination which can be varied in order to reduce the angle at which the orbit of the Space Station and the chaser intersect and so reduce the change in velocity required by the chaser to accomplish the plane change into the ISS orbit. Without this exploitation of orbital mechanics, the two-orbit profile was found to come with excessive propellant consumption and would not have been practical.


Setting the Inter-Orbit Angle via Inclination Modification – Image: RSC Energia/TSNIIMASH "Cosmonautics & Rocket Engineering"

If accepting a 0.65° angular separation in RAAN (Right Ascension of Ascending Node), the planar launch window will broaden by ±2.5 minutes, allowing some leeway in the setup of the phase angle by the Space Station. But as consequence, the angle at which the ISS orbit and that of Progress/Soyuz intersect will be 0.51° and it would cost the spacecraft over 66m/s of delta-v to accomplish the plane change. Varying the orbital inclination by ±0.18° will allow Soyuz to accomplish the plane change at a much more manageable delta-v of 25m/s.

Widening the planar window to ±5 minutes (corresponding to phase angles of 20°) will require an inclination change of ±0.35° and a delta-v of 50m/s for the plane change, still manageable for the Soyuz/Progress vehicle within its typical propellant margin.

The two-orbit profile will also make use of the new capabilities of the Soyuz/Progress MS series, specifically its ability of orbit determination through satellite navigation and/or post-insertion ranging from the ground in order to target the orbit-raising maneuvers per the actual injection orbit and directly maneuver to the point wh ere the Automated Rendezvous Sequence can be initiated.

Additionally, the upgraded control system and KURS navigation system are capable of dealing with greater state vector deviations at the start of the automated rendezvous, allowing some margin in injection/maneuver accuracy.

Approval for the upcoming Progress MS-07 mission to use this new flight profile only came this week with liftoff on a Soyuz 2-1A rocket targeted for 9:32:06 UTC on October 12, 2017 from Site 31/6 at the Baikonur Cosmodrome. If all goes well, Progress MS-07 should be inbound for an automated docking to the Pirs module of the Space Station three hours and 24 minutes after liftoff. Should anything off-nominal occur during the express flight, the craft would revert to the longer two-day approach.

When the two-orbit rendezvous profile will be introduced for crewed missions will largely depend on the success of Progress MS-07.

Progress MS-07 Cargo Ship to Attempt Fastest ISS Rendezvous on Thursday
October 11, 2017

A Soyuz 2-1A rocket rolled out to its launch pad at the Baikonur Cosmodrome at sunrise on Tuesday, greeted by colorful skies as the stage is set for liftoff on Thursday to send the Progress MS-07 cargo ship on an ultra-fast rendezvous with the International Space Station. Progress MS-07 is the first spacecraft aiming to link up with the Space Station after just two orbits around the Earth, traveling only three and a half hours from the Kazakh launch site to its orbital destination.

Preparations are proceeding on track for liftoff at 9:32:03 UTC on Thursday at which point the International Space Station will be 165 Kilometers south-west of the Baikonur launch pad, set to "overtake" the ascending Soyuz rocket half a minute into its climb to orbit so that Progress can be injected into a position behind & some 200 Kilometers below the Station.

From there, the spacecraft will execute a novel approach to ISS that encompasses a combined plane-change & orbit-raising effort on the craft's first lap around Earth that lines it up for an automated rendezvous guided by the KURS Navigation System, ideally inbound for a fully automated lap around the Space Station and a straight-in approach on auto pilot for docking to the Pirs module three hours and 24 minutes after launch.

Should anything be amiss during the new rendezvous procedure, Mission Controllers in Moscow have the option of backing out and setting up a two-day rendezvous per the tried-and-true procedure that has been in use for decades.

Implementing a two-orbit flight profile allows around two and a half hours to be cut from the currently-used four-orbit profile that was inaugurated in 2012 for the uncrewed Progress spacecraft for a series of tests before becoming the preferred method for crewed Soyuz flights to ISS in 2013. The fast-track rendezvous was born out of a desire to reduce the two-day ride on the cramped Soyuz to only a few hours spent within the confines of the spacecraft before crews could enjoy the comforts of ISS.


Illustration of the initial phase angle as starting condition for a planar rendezvous – Image: FAA

However, the faster the rendezvous gets, the tighter the constraints will be in the orbital geometry between the chasing spacecraft and the International Space Station. Constraining an orbital rendezvous is the requirement to launch the chaser into the orbital plane of the target spacecraft with the target typically orbiting ahead of the chaser at the point of orbital insertion. The distance between the two at orbital insertion is typically expressed as an angular value known as the phase angle.

When time is not of the essence, the phase angle can be quite large as the chaser, injected into a lower orbit with shorter period than the target, has a number of options to raise its orbit and catch up with the target over a period of days. If a rendezvous in a matter of hours is desired, orbital geometry between the chaser and target has to be such that the target is within a very narrow phase angle window when the Earth's rotation carries its orbital plane over the launch site.

In case of Soyuz and ISS, the allowable phase angle can be as large as 150 degrees for a two-day approach, but for the four-orbit flight profile, the allowable phase angle can be no more than 35 degrees. This requires a multi-week setup via small orbit-raising maneuvers that modify the Station's orbital period in order to place it at the correct position in its orbit when the planar launch time arrives.


Two-Orbit Rendezvous Profile – Image: RSC Energia/TSNIIMASH "Cosmonautics & Rocket Engineering"

For a two-orbit rendezvous, the allowable phase angle range would shrink further and require even more elaborate setup of the orbital geometry. However, Russian trajectory teams came up with a trade-off between planar and phase angle constraints in what is known as a Quasi Coplanar Insertion. This broadens the planar launch window by up to several minutes to create some leeway in the setup of the phase angle and so allow the chaser to launch at the optimized phase angle but slightly out-of-plane.

The planar mismatch has to be made up through maneuvering by the chaser, coming at the cost of additional propellants, though a second trick will keep the additional fuel expense to a minimum. This is realized by launching the chaser into a slightly different orbital inclination than ISS to set up the most efficient inter-orbit angle and so bring the chaser to its destination within the normal fuel margins of the traditional rendezvous procedure.

The intricacies of orbital rendezvous on the expressway are explained in our recent article outlining the nuts and bolts of Russia's planned two-orbit rendezvous profile and can be found here.

When the two-orbit rendezvous will be implemented on crewed Soyuz missions will largely depend on the success of Progress MS-07. Russia finds itself in the advantageous position of having two very similar spacecraft in use for cargo and crew missions, allowing the unmanned Progress ships to act as a pathfinder whenever new technology or new flight techniques, like the two-orbit rendezvous, are introduced.

The primary purpose of the Progress MS-07 mission is to keep up a steady chain of supplies to the International Space Station that stepped down to only two permanent crew members on the Russian Segment earlier this year. This was implemented due to low workload on the Russian side and to cut costs by reducing the number of annual Progress missions to three. MS-07 is the third and last Progress headed to ISS this year, booked for a half-year docked stay through April 2018.

Progress MS-07 is loaded with the typical cargo mix including refueling propellant for transfer to ISS, water for crew consumption and oxygen generation, pressurized gas to top up the Station's atmosphere, and over 1.2 metric tons of dry cargo including food, crew supplies and science gear.

Taking its vertical position atop the launch pad at Site 31/6, Soyuz 2-1A is gearing up for an eight-hour countdown operation beginning at sunrise on Thursday. Initial countdown activities include a final set of checkouts on the launch vehicle and spacecraft, the installation of batteries on the Soyuz booster and preparations for the tanking procedure. The Russian State Commission will meet at T-5 hours in order to provide the green light for propellant loading, looking at the status of countdown operations and the results of launch vehicle testing performed over the last two days.

Tanking will pick up at T-4 hours to pump around 274 metric tons of rocket-grade Kerosene and -183°C Liquid Oxygen into the 12 tanks on the boosters, core stage and Block I upper stage. While propellants are flowing into the vehicle, engineers will also fill the core stage and four strap-on boosters with Hydrogen Peroxide, in use to drive the engine turbopumps during flight. The boosters and core also receive Liquid Nitrogen, to be heated up during flight to act as pressurant gas for the propellant tanks.

Propellant loading will wrap up inside two hours to launch, to be followed by final close out activities at the launch pad and the reconfiguration of the rocket's digital guidance system. Soyuz 2-1A will be revealed atop its launch pad in the last hour of the countdown and all personnel will depart the complex for the fast-paced automated countdown sequence, starting at the T-6-minute mark with the insertion of the launch key to signal final approval for liftoff.

Standing fully-fueled for launch, Soyuz will purge its engines to ensure a clean ignition, pressurize its tanks and transition to onboard power. At T-1 minute, the vehicle will be handed control of the countdown, leading up to the Launch Command at T-20 seconds that triggers the ignition of the RD-107A and RD-108A engines on the core stage and boosters – initially spinning up the turbopumps and going through a preliminary thrust stage before throttling to a combined launch thrust of 422 metric-ton force to overcome counterweights and lift the 46-meter tall vehicle off the ground.

Liftoff is set for precisely 9:32:03 UTC to enable Progress to be injected in a precise position behind and below the International Space Station in order to catch up after just two laps around the planet. While Soyuz will be transitioning from a vertical climb onto a north-easterly departure path, the Space Station will pass close to 400 Kilometers overhead, overtaking the rising launch vehicle.

Racing away from the Baikonur Cosmodrome toward the Russian-Kazakh border, Soyuz will push through the sound barrier and encounter Maximum Dynamic Pressure just over a minute after taking off.

The four boosters will burn for 1 minute and 57.5 seconds, each consuming 39 metric tons of propellant to help accelerate the Soyuz to over 1.5 Kilometers per second. Separation of the 19.6-meter long boosters will be accomplished through pyrotechnics and pistons, sending them tumbling away from the still-firing core stage toward a crash landing some 355 Kilometers from the launch site.

With the boosters gone, Soyuz will rely on its RD-108A engine alone, generating 102 metric ton-force of thrust when flying through the rarefied upper atmosphere. The core stage will fire until four minutes and 46 seconds into the flight, separating from the upper stage in hot-staging mode with the RD-0110 engine firing up just as the pyrotechnic separation system is initiated to send the 27.8-meter core toward re-entry and impact 1,550km from the launch site.

Ten seconds after ignition of the Block I third stage, Soyuz 2-1A will jettison the protective launch shroud to reveal the Progress MS-07 spacecraft for the rest of its ride into orbit. At the same time, the aft section covers of the Block I are released to fully expose the engine section with its four main nozzles and four gimbaled verniers for attitude control.

Generating 30-metric-ton-force of thrust, the third stage will consume nearly 25 metric tons of propellants over a burn of three minutes and 58 seconds to push the 7,200-Kilogram spacecraft into orbit. Separation of the Progress MS-07 spacecraft is expected eight minutes and 48 seconds after liftoff, marking the end of the mission for the Soyuz rocket and the beginning of an express rendezvous for the Progress cargo vehicle.

Immediately after arriving in orbit, the Progress will deploy its two power-generating solar arrays and KURS navigation antennas – events closely watched by Mission Control Moscow as any anomaly in these early steps would prompt a switch to the longer rendezvous scheme. An initial test of the flight control and KURS navigation system will be performed while Progress is still in range of Russian ground stations for 12 minutes following orbital insertion.


Image: TsUP/Roscosmos

Heading off on its first lap around Earth, Progress MS-07 will have pressurized its Unified Propulsion System and entered three-axis stabilization, holding a pre-programmed orientation for its first orbital maneuver. The KTDU main propulsion system is expected to make its first firing 41 minutes after launch, starting the process of lining up the orbital plane of Progress with that of ISS and maneuvering the spacecraft closer to the Station's orbital altitude.

The Automated Rendezvous Sequence will be commanded to start 62 minutes into the mission, taking the usual 100 minutes from Rendezvous Initiation to the arrival of the spacecraft at the Ballistic Targeting Point. Both the four-orbit and two-orbit rendezvous, retain the overall architecture of the Automated Rendezvous Sequence from the traditional two-day flight scheme as Russian ballisticians did not want to tamper with a very well-proven technique.

Twenty minutes after rendezvous initiation, Progress will execute a large ground-targeted burn to continue climbing toward ISS and in the process slow the speed at which it closes the phase angle between the two craft. This will be followed by a small correction maneuver one hour and 46 minutes into the flight to adjust for injection inaccuracies by the Soyuz launch vehicle ahead of starting the relative navigation phase of the rendezvous when activating the KURS system on Progress and Station.

Through KURS, Progress will initially keep track of its angular geometry with ISS before establishing a firm signal lock to obtain range, range rate and additional angular parameters for the calculation of subsequent rendezvous maneuvers. A major rendezvous impulse is expected two hours and six minutes into the mission to guide Progress onto a flight path toward the targeting point, located one Kilometer from the Station to preserve the option of a passive rendezvous abort should anything go wrong over the next hour of the approach.

The KURS system will be validated at distances of 80 and 15 Kilometers and the Russian ISS crew members, Sergey Ryazanskiy and Aleksandr Misurkin, will test out the TORU system by controlling the Progress remotely for a brief moment to ensure they could manually dock the vehicle in case of anomalies inside the last 400 meters of the rendezvous. A series of three rendezvous impulse maneuvers, the first two using the 300-Kilogram-force main engine, will occur around the Ballistic Targeting Point to reduce the intentional targeting offset and transition the Progress onto a path to ISS.

The flyaround will commence when Progress reaches the 400-meter mark to ISS, expected right at the T+3-hour mark. Through a slow lap around the Station, Progress will line up with the Pirs module on the Earth-facing side of the Station for a brief period of Stationkeeping before the Progress is commanded into a straight-in approach to cover the last 180 meters to docking.

Docking is expected at 12:56:35 UTC (+/-3min) to mark a new record for the fastest docking with the International Space Station. Progress will retract its docking probe shortly thereafter and hooks will close to form a rigid interface between the two spacecraft to enable hatches to be opened later on Thursday for an express supplies delivery.

А может кто-нибудь запостить сюда список грузов с указанием веса?

Завтра на сайте ЦУП опубликуют, сразу сюда прикреплю.
Они стали выкладывать пресс-релизы с информацией непосредственно перед событием или уже после.

Про все не скажу, а что именно интересует? Общая масса - 7427 кг, полезной нагрузки - 38.

С Байконура запустят космический корабль "Прогресс МС-07" с грузами для МКС
 12 октября, 0:29 UTC+3
 Пуск ракеты-носителя "Союз-2.1а" с транспортным грузовым кораблем запланирован на 12:32 мск
 
МОСКВА, 12 октября. /ТАСС/. Транспортный корабль "Прогресс МС-07" с грузами для Международной космической станции (МКС) будет запущен в четверг с космодрома Байконур с помощью ракеты-носителя "Союз-2.1а". Об этом ТАСС сообщили в Центре управления полетами.
"Пуск ракеты-носителя "Союз-2.1а" с транспортным грузовым кораблем "Прогресс МС-07" запланирован на 12 октября 2017 года в 12:32 мск", - сказали в Центре.
Примерно через 9,5 минуты после старта ракета выведет корабль на низкую околоземную орбиту. После отделения от третьей ступени носителя "Прогресс" в автоматическом режиме продолжит полет к МКС.

 Схема полета
 
Как сообщил в конце августа ТАСС представитель госкорпорации "Роскосмос", "Прогресс МС-07" впервые может осуществить полет к станции по двухвитковой схеме - примерно за три часа. Однако окончательное решение о схеме полета "грузовика" к МКС будет принято на заседании госкомиссии, которое пройдет на Байконуре в четверг утром.
Предыдущие два запуска кораблей серии "Прогресс МС", проведенные в этом году, были выполнены по классической длинной схеме, когда полет "грузовиков" до цели занимает двое суток. Также Роскосмос использует короткую четырехвитковую схему, при которой корабли добираются до МКС за шесть часов. Она также была впервые отработана на грузовом корабле - за шесть часов до станции в августе 2012 года долетел "Прогресс М-16М". По этой же четырехвитковой схеме к МКС 13 сентября был запущен пилотируемый "Союз МС-06" с экипажем новой экспедиции.
 
Стыковка и груз

В зависимости от того, какую схему полета выберет госкомиссия, "Прогресс" может достичь МКС около 15:30 мск или 18:30 мск четверга либо уже только днем в субботу, 14 октября.
Сближение корабля со станцией и причаливание к стыковочному узлу служебного модуля "Звезда" должны пройти в автоматическом режиме. Контролировать процесс стыковки будут находящиеся на станции российские космонавты Сергей Рязанский и Александр Мисуркин, при необходимости они пристыкуют "Прогресс" вручную.
Корабль доставит на МКС 2,5 т различных грузов, в том числе сухие грузы, топливо, воду, сжатые газы, материалы и аппаратуру для проведения экспериментов на борту станции, посылки экипажу и свежие продукты.
