Soyuz MS-13 arrives at ISS
The three new crew members of Expeditions 60 and 61 to the International Space Station, ISS, blasted off from Baikonur Cosmodrome in Kazakhstan on July 20, 2019 aboard the Soyuz MS-13 spacecraft. In less than nine minutes after liftoff, the Soyuz-FG launch vehicle successfully released the crew vehicle into orbit.

Preparations for flight
During various incarnations of the ISS flight manifest, the launch of Soyuz MS-13 spacecraft mission was scheduled on July 10, July 24 and July 6, 2019. As of the beginning of 2019, the spacecraft was scheduled to remain in orbit for 215 days and return to Earth on Feb. 6, 2020, however by the beginning of February 2019, the landing was advanced to December 18 of the same year. Then, at the beginning of April 2019, Roskosmos decided to postpone the launch of Soyuz MS-13 from July 6 to July 20. The latest schedule changes were reportedly related to delays with the introduction of NASA's crew vehicles at the end of 2019.
The active preparations for the mission began on May 14, when the spacecraft was transported into the vacuum chamber at Site 254 in Baikonur for tests using a mixture of helium and air to ensure the absence of leaks in the ship's pressurized compartments. On July 1, the solar panels of the spacecraft were exposed to an array of electric lights testing their ability to supply power.
On July 4, the primary and backup crews preparing for the Soyuz MS-13 mission traveled to Baikonur Cosmodrome for final training. The primary crew included the Russian cosmonaut Aleksandr Skvortsov, European astronaut Luca Parmitano and NASA astronaut Andrew Morgan. The backup crew was comprised of Sergei Ryzhikov (Roskosmos), Tom Marshburn (ESA) and Soichi Noguchi (Japan). A day after arriving at Baikonur, both teams worked inside the flight-worthy Soyuz MS-13 undergoing final preparations at the spacecraft processing building at Site 254. The cosmonauts and astronauts also tried on their Sokol spacesuits and checked them for air leaks. After completion of the familiarization training, Soyuz MS-13 was sent to fueling, which was completed on July 8 and, on the same day, the spacecraft was returned to Site 254 for final checks.
On July 10, Soyuz MS-13 was integrated with its launch vehicle adapter, and on July 12, it underwent its final visual inspection and on the same day, the ship was rolled inside its payload fairing.
On July 16, the payload section with the spacecraft was transported to the vehicle assembly building at Site 112 and the next day, it was integrated with the Emergency Escape System, SAS, and the third stage of the Soyuz launch vehicle. The resulting upper composite was then transferred to the transporter/erector, where it was connected to the lower booster stages of the Soyuz rocket. Before the end of the day, the technical management and the State Commission gave the green light to the rollout of the vehicle to the launch pad at Site 1 next morning.
Soyuz MS-13 launch profile
A Soyuz-FG rocket carrying the Soyuz MS-13 (No. 746) transport spacecraft lifted off from Site 1 in Baikonur on July 20, 2019, at 19:28:20.238 Moscow Time (12:28 p.m. EDT, 16:28 UTC). The spacecraft carried Russian cosmonaut Aleksandr Skvortsov, European astronaut Luca Parmitano and NASA astronaut Andrew Morgan to the International Space Station, ISS. Aboard the station, the trio will be a part of Expeditions 60 and 61.
The launch vehicle followed a standard ascent profile inserting the spacecraft into an initial parking orbit with an inclination of 51.6 degrees toward the Equator exacty 8 minutes and 48 seconds after liftoff. The spacecraft separated from the third stage of the launch vehicle at 19:37 Moscow Time.
According to the Russian mission control in Korolev and Roskosmos, Soyuz MS-13 entered an initial orbit with the following parameters:
Rendezvous and docking
Following a six-and-a-half-hour, four-orbit rendezvous profile, Soyuz MS-13 was scheduled to dock at the aft port of the Zvezda Service Module, SM, a part of the Russian Segment of the ISS at 6:51 p.m. EDT (July 21, 01:51 Moscow Time). According to the Russian mission control, the actual docking took place at 01:47:52 Moscow Time on July 21 (6:48 p.m. EDT on July 20, according to NASA).
According to Russian mission control, the post-docking activities had the following timeline:
The hatches between the spacecraft and the station were scheduled to open around two hours after docking around 03:50 Moscow Time on July 21 (8:50 p.m. EDT on July 20). In reality, they were opened nearly 15 minutes late, after some push on the Soyuz' hatch by Oleg Ovchinin from the station's side.
Aboard the ISS, the Soyuz MS-13 crew will join three members of the Soyuz MS-12 crew.
