Soyuz MS-02 was a 2016 Soyuz spaceflight that was planned for a 23 September 2016 launch, but because of technical difficulties it launched on 19 October 2016. It transported three members of the Expedition 49 crew to orbit and docked with the International Space Station. MS-02 was the 131st flight of a Soyuz spacecraft. The crew consists of a Russian commander and flight engineer, as well as an American flight engineer. MS-02 docked with (Poisk (MRM-2) module on Friday, October 21, 2016.
MS-02 returned to Earth on Monday, April 10, 2017. The landing occurred at 11:20 UTC. The total flight duration was 173 days.

Soyuz 134 MS-02
Instead of relying on ground stations for orbital determination and correction, the now-included Satellite Navigation System ASN-K (Russian: АСН-К, Аппаратура Спутниковой Навигации) relies on GLONASS and GPS signals for navigation. It uses four fixed antennas to achieve a positioning accuracy of 5 m (16 ft), and aims to reduce that number to as little as 3 cm (1.2 in) and to achieve an attitude accuracy of 0.5°.
The old radio command system, the BRTS (Russian: БРТС Бортовая Радио-техническая Система) that relied on the Kvant-V was replaced with an integrated communications and telemetry system, EKTS (Russian: ЕКТС, Единая Kомандно-Телеметрическая Система). It can use not only the Very high frequency (VHF) and Ultra high frequency (UHF) ground stations but, thanks to the addition of an S-band antenna, the Lutch Constellation as well, to have theoretical 85% of real time connection to ground control. But since the S-band antenna is fixed and Soyuz spacecraft cruises in a slow longitudinal rotation, in practice this capability might be limited due to lack of antenna pointing capability. It may also be able to use the American TDRS and the European EDRS in the future.
The old information and telemetry system, MBITS (Russian: МБИТС, МалогаБаритная Информационно-Телеметрическая Система), has been fully integrated into the EKTS.
The old VHF radio communication system (Russian: Система Телефонно-Телеграфной Связи) Rassvet-M (Russian: Рассвет-М) was replaced with the Rassvet-3BM (Russian: Рассвет-3БМ) system that has been integrated into the EKTS.
The old 38G6 antennas are replaced with four omnidirectional antennas (two on the solar panels tips and two in the PAO) plus one S-band phased array, also in the PAO.
The descent module communication and telemetry system also received upgrades that will eventually lead to having a voice channel in addition to the present telemetry.
The EKTS system also includes a COSPAS-SARSAT transponder to transmit its coordinates to ground control in real time during parachute fall and landing.
All the changes introduced with the EKTS enable the Soyuz to use the same ground segment terminals as the Russian Segment of the ISS.
The new Kurs-NA (Russian: Курс-НА) automatic docking system is now made indigenously in Russia. Developed by Sergei Medvedev of AO NII TP, it is claimed to be 25 kg (55 lb) lighter, 30% less voluminous and use 25% less power. An AO-753A phased array antenna replaced the 2AO-VKA antenna and three AKR-VKA antennas, while the two 2ASF-M-VKA antenna were moved to fixed positions further back.
The docking system received a backup electric driving mechanism.
Instead of the analog TV system Klest-M (Russian: Клест-М), the spacecraft uses a digital TV system based on MPEG-2, which makes it possible to maintain communications between the spacecraft and the station via a space-to-space RF link and reduces interferences.
A new Digital Backup Loop Control Unit, BURK (Russian: БУРК, Блок Управления Резервным Контуром), developed by RSC Energia, replaced the old avionics, the Motion and Orientation Control Unit, BUPO (Russian: БУПО, Блок Управления Причаливанием и Ориентацией) and the signal conversion unit BPS (Russian: БПС, Блок Преобразования Сигналов).
The upgrade also replaces the old Rate Sensor Unit BDUS-3M (Russian: БДУС-3М, Блок Датчиков Угловых Скоростей) with the new BDUS-3A (Russian: БДУС-3А).
The old halogen headlights, SMI-4 (Russian: СМИ-4), have been replaced with the LED powered headlight SFOK (Russian: СФОК).
A new black box SZI-M (Russian: СЗИ-М, Система Запоминания Информации) that records voice and data during the mission was added under the pilot's seat in the descent module. The dual unit module was developed at AO RKS corporation in Moscow with the use of indigenous electronics. It has a capacity of 4 Gb and a recording speed of 256 Kb/s. It is designed to tolerate falls of 150 m/s (490 ft/s) and is rated for 100,000 overwrite cycles and 10 reuses. It can also tolerate 700 °C (1,292 °F) for 30 minutes.
The Soyuz MS received the following upgrades with respect to the Soyuz TMA-M:

The fixed solar panels of the SEP (Russian: CЭП, Система Электропитания) power supply system have had their photovoltaic cell efficiency improved to 14% (from 12%) and collective area increased by 1.1 m2 (12 sq ft).
A fifth battery with 155 amp-hour capacity known as 906V was added to support the increased energy consumption from the improved electronics.
Additional micro-meteoroid protective layer was added to the BO orbital module.
The new computer (TsVM-101), weighs one-eighth that of its predecessor (8.3 kg versus 70 kg) while also being much smaller than the previous Argon-16 computer.

While as of July 2016 it is not known whether the propulsion system is still called KTDU-80, it has been significantly modified. While previously the system had 16 high thrust DPO-B and six low thrust DPO-M in one propellant supply circuit, and six other low thrust DPO-M on a different circuit, now all 28 thrusters are high thrust DPO-B, arranged in 14 pairs. Each propellant supply circuit handles 14 DPO-B, with each element of each thruster pair being fed by a different circuit. This provides full fault tolerance for thruster or propellant circuit failure. The new arrangement adds fault tolerance for docking and undocking with one failed thruster or de-orbit with two failed thrusters. Also, the number of DPO-B in the aft section has been doubled to eight, improving the de-orbit fault tolerance.

The propellant consumption signal, EFIR was redesigned to avoid false positives on propellant consumption.
The avionics unit, BA DPO (Russian: БА ДПО, Блоки Автоматики подсистема Двигателей Причаливания и Ориентации), had to be modified for changes in the RCS.
