Keeping up with the ISS

Current spacecraft docked at ISS. Seems kind of empty now that some spaceships have departed. NASA.

I've had a little gap in my space reporting since early March, but that included an excellent trip to the Kennedy Space Center. So let's see how mankind's orbiting outpost has been doing. Currently, there is only one robotic cargo vessel (Progress 66) and one crew vehicle (Soyuz MS-03) docked. Wait - isn't it more usual to have two crewed vehicles there?

Touchdown! Expedition 50 makes it back to Kazakhstan in a Soyuz capsule (MS-02).
 
Expedition 50 came to a close on April 10 when Commander Shane Kimbrough and cosmonauts Sergey Rizhikov and Andrey Borisenko left the ISS in Soyuz MS-02 and landed safely in the open steppes of Kazakhstan. That left Expedition 51 in charge of the station, with NASA astronaut Peggy Whitson n command supported by flight engineers Oleg Novitskiy (Roscosmos) and Thomas Pesquet (ESA).

Unmanned cargo spacecraft have also been on the move. The Dragon 10 spaceship was loaded with items for return to Earth and undocked on March 19. It re-entered the atmosphere and safely deployed a parachute, landing it in the Pacific Ocean for a quick recovery and return to SpaceX for evaluation.

Before the conclusion of Expedition 50, there was another important spacewalk to continue preparations for the station to begin receiving Non-NASA manned spacecraft from Boeing and SpaceX next year. On March 30, Peggy Whitson and Shane Kimbrough completed a six-and-a-half hour EVA, connecting a computer relay box as well as connecting cables and wires on the Pressurized Mating Adapter -3 (PMA-3). During the EVA, Peggy broke a spacewalking record, making an eighth EVA by a woman astronaut.

Next week will see more cargo spacecraft and new cremembers arriving at the ISS.
