On August 4, 2023, the US "Cygnus” CRS-19 (NG-19, the S. S. Laurel Clark) private unmanned supply spacecraft was docked to the International Space Station (ISS). The Cygnus spacecraft was grappled by a robotic arm at 09:52 UTC. The cargo spacecraft was docked to the station’s "Unity” module at 12:28 UTC. The spacecraft delivered about 3500 kilograms of supplies to the Space Station.

On August 2, 2023 at 00:31 UTC the "Cygnus” privately owned U.S. unmanned supply spacecraft was launched from the Mid-Atlantic Regional Spaceport (MARS), a commercial space launch facility located at the southern tip of NASA's Wallops Flight Facility on Wallops Island, Virginia, USA. The spacecraft was orbited by the “Antares-230” rocket-carrier. The "Cygnus” NG-19 (the S. S. Laurel Clark), previously known as CRS OA-19, unmanned supply spacecraft, built by U.S. space firm Orbital Sciences Corp., was orbited on its cargo resupply mission to the International Space Station. CRS means Commercial Resupply Services.

On July 20, 2023 Chinese cosmonauts Jing Haipeng and Zhu Yangzhu performed the spacewalk to install and lift the bracket for panoramic camera B of the core module; to unlock and lift the panoramic camera A/B of the “Mengtian” lab module. The EVA lasted 7 hours and 55 minutes. It was the 1^st spacewalk for both Jing Haipeng and Zhu Yangzhu.

On June 30, 2023 at 14:30 UTC the "Dragon” capsule splashed down in the Atlantic Ocean, off the coast of Jacksonville, Florida, USA. It was the "SpaceX CRS-28” mission.

On June 29, 2023 at 16:30 UTC, the Dragon CRS-28 spacecraft was undocked from the International Space Station.

On June 22, 2023, Russian cosmonauts Sergey Prokopyev and Dmitry Petelin performed the extra vehicle activities (EVA – spacewalk) to retrieve several experiment packages and to install communications equipment on “Zvezda” and “Poisk” modules. The EVA lasted 6 hours and 24 minutes. It was the 7^th EVA for Sergey Prokopyev and the 5^th EVA for Dmitry Petelin. It was the 170^th EVA performed by Soviet/Russian cosmonauts since 1965.

On June 15, 2023, US astronauts Steven Bowen and Warren Hoburg performed the spacewalk to install an iROSA (International Space Station Roll-Out Solar Array) on the 1B power channel on the starboard truss. The EVA lasted 5 hours and 35 minutes. It was the 10^th spacewalk for Steven Bowen and the 2^nd spacewalk for Warren Hoburg.

On June 09, 2023, US astronauts Steven Bowen and Warren Hoburg performed the spacewalk to install an upgraded iROSA (International Space Station Roll-Out Solar Array) on the 1A power channel on the starboard truss of the station. The EVA lasted 6 hours and 3 minutes. It was the 9^th spacewalk for Steven Bowen and the 1^st spacewalk for Warren Hoburg.

On June 5, 2023 at 19:10 UTC (on June 6 Beijing time), the Chinese “Tianzhou-5” unmanned supply spacecraft was docked to the forward docking port of the “Tianhe” core module of the Chinese “Tiangong” space station after more than a month of independent flying. The cargo spacecraft undocked from “Tiangong” on May 05, 2023 to leave room for its successor, “Tianzhou-6”. It had been flying freely for 33 days before the re-docking.

On June 6, 2023 at 09:54 UTC, the private U.S. unmanned supply spacecraft, the "Dragon” SpX-28 (CRS-28 flight), was successfully docked to the International Space Station (Harmony zenith docking port).
