Soyuz rocket positioned on launch pad for station resupply flight
February 9, 2018 Stephen Clark

...
A Russian Soyuz booster and an automated Progress resupply ship reached their launch pad Friday at the Baikonur Cosmodrome in Kazakhstan, two days before firing into orbit test out a new expedited rendezvous sequence that will culminate in the Progress spacecraft's docking with the International Space Station just three-and-a-half hours after launch.

The Soyuz-2.1a rocket, a modernized version of Russia's venerable Soyuz launcher, rolled out of its assembly hangar — known by the Russian acronym MIK — at the Baikonur Cosmodrome before sunrise Friday.

Towed aboard a specialized rail car behind a train engine, the Soyuz reached Launch Pad No. 31 and was raised vertical later Friday morning. Retractable gantry towers moved into position around the Soyuz rocket to give ground crews access to the launcher for final pre-flight preparations.

Liftoff of the Soyuz-2.1a rocket is scheduled for 0858:45 GMT (3:58:45 a.m. EST; 2:58:45 p.m. Baikonur time) Sunday.

The three-stage Soyuz booster will deliver the Progress MS-08 supply ship — known as Progress 69P in the space station's visiting vehicle manifest — into orbit approximately nine minutes later. The Progress spacecraft's power-generating solar panels and navigation antennas will unfurl moments later, and the robotic resupply and refueling freighter will begin firing its engines to match orbits with the space station.

A Kurs rendezvous radar will guide the Progress on its approach to a docking port on the aft end of the space station's Zvezda service module.

The Progress MS-08 supply ship is slated to complete its orbital link-up at 1224 GMT (7:24 a.m. EST).

Russian engineers aim to demonstrate a new express rendezvous sequence on Sunday's flight, cutting in half the time most Progress resupply ships and Soyuz crew ferry craft take to reach the space station after liftoff. The three-and-a-half hour rendezvous profile would set a record for any vehicle visiting the International Space Station.

Officials hope to use the shortened rendezvous profile on Soyuz crew missions, once demonstrated on unpiloted Progress missions. The change will reduce the workload and time spent inside the cramped Soyuz capsule for future station crews.

Russia began shortening Progress and Soyuz flights to the space station a few years ago, reducing the standard approach time from two days to around six hours. Engineers launched a Progress supply ship on an accelerated six-hour rendezvous for the first time in 2012, and began using the fast approach for Soyuz crew missions in 2013.

The six-hour trip occurs as the space station and visiting spaceship make four orbits of the Earth, while the even quicker journey Sunday will take place during just two orbits.

Russia intended to demonstrate the two-orbit, three-and-half hour rendezvous on the most recent Progress resupply mission in October, but a last-minute abort in the Soyuz rocket's countdown forced a two-day delay in the launch, prompting officials to scrap the plan.

The constraints of orbital mechanics only permit the shortened three-and-a-half hour approach sequence if the Soyuz rocket blasts off at just the right moment, requiring a special alignment between the Baikonur launch base and the space station's orbit that only occurs on certain days.

Assuming the Progress MS-08 supply carrier lifts off at Sunday's instantaneous launch opportunity, Russian mission controllers will go forward with the two-orbit rendezvous plan. Officials have the option to revert to a two-day, 34-orbit flight plan.

The Progress spacecraft is carrying 1,962 pounds (890 kilograms) of propellant for the station, plus 926 pounds (420 kilograms) of water, 53 pounds (24 kilograms) of compressed air and 48 pounds (22 kilograms) of compressed oxygen for delivery to the orbiting research lab, according to a manifest released by Roscosmos, the Russian space agency.

Ground crews at the Baikonur Cosmodrome packed the pressurized cabin inside the Progress MS-08 supply ship with 3,064 pounds (1,390 kilograms) of equipment, scientific hardware, food and supplies for the station's six-person crew, Roscosmos said.

МОСКВА, 9 фев — РИА Новости. Ракету "Союз-2.1а", которой предстоит отправить к Международной космической станции грузовой корабль "Прогресс МС-08", установили на стартовый комплекс на космодроме Байконур, сообщает "Роскосмос".

Запуск запланирован на 11:58:45 (мск) 11 февраля.

Космический грузовик "Прогресс МС-08" впервые в истории отправят к МКС по сверхкороткой двухвитковой схеме. По предварительным расчетам баллистиков, корабль должен будет добраться до станции через три часа 27 минут после старта. После отработки этой технологии ее предполагается использовать и для пилотируемых кораблей "Союз"

Спойлер

Изначально по новой схеме должен был лететь "Прогресс МС-07", старт которого планировали на 12 октября 2017 года. Но тогда автоматика отменила пуск, и старт перенесли на резервную дату — 14 октября, когда баллистические условия уже не позволяли использовать новую схему. "Прогресс МС-07" добрался до станции по стандартной схеме за двое суток.

Сейчас самым быстрым способом попасть на МКС является полет по четырехвитковой схеме, который занимает порядка шести часов.

"Прогресс МС-08" должен доставить на МКС 1390 килограммов сухих грузов, топливо, воду и баллоны со сжатым воздухом и кислородом. В грузовом отсеке уложено научное оборудование, в том числе летный комплект аппаратуры для эксперимента по мониторингу миграций диких животных "Икарус" (его российские космонавты должны будут установить на внешней поверхности станции во время следующего выхода в открытый космос), комплектующие для системы жизнеобеспечения, а также контейнеры с продуктами, одеждой, лекарствами и средствами личной гигиены для членов экипажа.

Трансляция пуска запланирована на сайте Роскосмоса.

Soyuz Rocket Rolls out for Launch of Prog ress MS-08 Cargo Craft on Two-Orbit ISS Rendezvous
February 9, 2018

Winter remained with a firm grip on Kazakhstan's Baikonur Cosmodrome on Friday when a Soyuz 2-1A emerged from its assembly hall and rolled to its launch pad for a Sunday liftoff with the Progress MS-08 cargo spacecraft on an expedited, two-orbit rendezvous with the International Space Station.

The first of three planned Progress missions of 2018 is targeting liftoff at 8:58 UTC and the Soyuz 2-1A rocket will be in operation for less than nine minutes to send the seven-metric-ton-spacecraft on its way toward a 12:24 UTC docking with the Station's Zvezda module.

If successful, Progress MS-08 will take the record for the fastest rendezvous with the International Space Station, cutting in half the current travel time for crewed Soyuz spacecraft that employ a four-orbit rendezvous scheme taking around six hours. The new two-orbit flight profile was originally planned to debut on the Progress MS-07 mission last October but had to be deferred when its Soyuz rocket encountered a rare ignition abort and had to move to its backup launch date – knocking the precise orbital geometry required for the fast approach out of place and reverting the mission to the standard two-day flight profile.

Roscosmos said on Friday that preparations are on track for liftoff on Sunday, at precisely 8:58:44 UTC when the International Space Station will be 260 Kilometers south-west of the Site 31/6 launch pad, set to overtake the ascending Soyuz rocket just over half a minute after it takes flight so that Progress can be injected into a position right behind and around 200 Kilometers below the Station.

Russia began implementing expedited rendezvous techniques in 2012 when the four-orbit flight profile debuted on the Progress cargo spacecraft for a series of tests before becoming the preferred method for crewed Soyuz missions in 2013 to ferry crews to their destination in space on the same day of launch to avoid them having to spend two nights in the confines of the Soyuz spacecraft.

This four-orbit flight profile comprises a pair of pre-programmed orbit raising maneuvers on the spacecraft's first lap around the planet followed by another pair of main engine burns on the second lap to correct for launch vehicle injection errors before the Automated Rendezvous Sequence starts on the third orbit to bring the spacecraft to the vicinity of ISS for a flyaround and straight-in approach to docking.

Further speeding up the rendezvous requires two critical elements: a) a more accurate launch vehicle so that dispersions or errors at orbital injection are so small corrective maneuvers can be eliminated (thus cutting the orbit #2 maneuvers) and b) a much stricter setup of orbital geometry or the development of a flight profile solution that allows the spacecraft to deal with a greater range of starting conditions. Additionally, Russian flight teams decided to keep the 100-minute Automated Rendezvous Sequence unchanged in order not to tamper with a procedure that has proven very effective and reliable over the years.

Soyuz 2-1A, utilizing the modern digital guidance system, provides a much higher precision in orbital injection than its Soyuz U/FG predecessors and allows the Orbit #2 maneuvers to be cut to yield a three-orbit flight profile. However, the goal of creating a two-orbit rendezvous necessitated additional modification of the flight profile.

Achieving the two-orbit link-up requires a very precise orbital geometry to be in place with respect to the position of ISS in its orbit when the orbital plane passes over the Baikonur Cosmodrome so that Progress can be injected at a very small phase angle to ISS (the initial angle separating the target and chaser spacecraft in their orbital plane).

Russian trajectory experts developed a solution that allowed some leeway in the phase angle requirements by combining phasing and plane-change maneuvers into a Quasi Coplanar Insertion Scheme in which a slight planar misalignment is acceptable to permit launching at the optimized phase angle and making up during flight by setting up the most fuel-efficient planar transfer through adjusting the orbital inclination of the chaser at launch.

The intricacies of Russia's Quasi Coplanar Insertion & Rendezvous are explained in detail here.

Should anything be amiss during Sunday's rendezvous attempt, Mission Controllers in Moscow have an option to back out of the express rendezvous and revert to a two-day trajectory per the tried-and-true procedure that builds on several decades of experience. As with the introduction of the four-orbit flight profile, Progress will again be the pathfinder for the faster two-orbit trajectory and only once it is well established will it be implemented for crewed missions, likely starting after the transition of Soyuz MS missions to the upgraded Soyuz 2-1A rocket in 2019.

The primary purpose of the Progress MS-08 mission is keeping up a steady chain of supplies to the International Space Station and its six crew members. It is the first of three planned Progress missions to ISS this year, though schedules remain fluid surrounding the departure of the Pirs module (with the help of a Progress craft) and the arrival of the Nauka Multipurpose Laboratory Module.

The cargo onboard Progress MS-08 comprises the typical mix between refueling propellant, water, compressed gas and dry cargo loaded into the pressurized section of the spacecraft. In total, the mission is carrying 2,496 Kilograms of cargo including 640kg of propellant for transfer to ISS, 420kg of water for crew consumption and oxygen generation, 46kg of oxygen to top up the Station's atmosphere and 1,390kg of dry cargo – food provisions, crew supplies, hygiene articles, maintenance gear, spacewalk equipment and experiment hardware.

Progress MS-08 is also hosting a technology demonstration experiment called Фазопереход "Phase Transition". This experiment deploys a series of new thermal control system components to the operational space environment to test their performance in a realistic flight scenario. Operated by TSNIIMASH, the experiment primarily looks into the efficiency of new heat pipes and radiators that rely on the phase transition of a working fluid to efficiently transport heat from electronic components to the radiator.
