A few hours ago, the Soyuz MS-26 spacecraft was launched from the Baikonur Cosmodrome in Kazakhstan and after a little more than three hours reached the International Space Station with three new crew members on board. It docked with the Station’s Rassvet module. As is becoming increasingly common for crewed trips as well, the ultra-fast track was used which halves the journey duration.

Northrop Grumman’s Cygnus spacecraft, launched last Sunday, August 4, has just reached the International Space Station and was captured by the Canadarm2 robotic arm. Astronaut Matthew Dominick, assisted by his colleague Jeanette Epps, will soon begin the slow maneuver to move the Cygnus until it docks with the Station’s Unity module after about two hours.

The Cygnus cargo spacecraft arrived on schedule despite some issues with a thruster burn that was scheduled to occur about 45 minutes after separation from SpaceX’s Falcon 9 rocket’s last stage. Initial reports indicated that the onboard computer had canceled the burn due to low pressure within the engine systems. Northrop Grumman engineers were able to compensate for the issue with a new burn schedule after reviewing pressure data and determining that it was still acceptable for the thrusters to work.

A few hours ago, Boeing’s CST-100 Starliner Calypso spacecraft docked with the International Space Station’s Harmony module, completing the first leg of its Boe-CFT (Boeing Crewed Flight Test) mission which began with the launch just over 24 hours earlier. After checking that the pressure was correctly balanced, the hatch was opened to allow Butch Wilmore and Suni Williams to enter the Station and begin their mission, which will last about a week.

A confirmation has arrived that three Chinese taikonauts from the Shenzhou 18 mission reached the Chinese space station Tiangong with an automated docking maneuver. They blasted off about 6.5 hours earlier atop a Long March-2F rocket from the Jiuquan Satellite Launch Center. They form the 7th crew of the Chinese space station and will remain there for about six months, the standard duration for a mission.

The three taikonauts, as the Chinese call their astronauts, of the Shenzhou 18 mission are Ye Guangfu, Li Cong, and Li Guangsu.

A little while ago the Soyuz MS-25 spacecraft, which blasted off about two days ago from the Baikonur Cosmodrome in Kazakhstan, has reached the International Space Station carrying one new crew member and two visitors. Astronaut Tracy Dyson of NASA is part of Expedition 70/71 while cosmonaut Oleg Novitskiy of Roscosmos and the Belarusian Marina Vasilevskaya will remain on the Station for a few days.
