SpaceX CRS-23 mission patch
SpaceX CRS-23, also known as SpX-23, was a Commercial Resupply Service mission to the International Space Station, successfully launched on 29 August 2021 and docking the following day. The mission was contracted by NASA and was flown by SpaceX using the Cargo Dragon C208. This was the third flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016. It was the second mission for this reusable capsule.
Along with SpaceX Crew-2 (Endeavour) and Inspiration4 (Resilience), C208 was one of three SpaceX Dragon 2 spacecraft in space simultaneously from 15 to 18 September 2021.

SpaceX plans to reuse the Cargo Dragons up to five times. Since it does not support a crew, the Cargo Dragon launches without SuperDraco abort engines, seats, cockpit controls or the life support system required to sustain astronauts in space. Dragon 2 improves on Dragon 1 in several ways, including lessened refurbishment time, leading to shorter periods between flights.
Cargo Dragon capsules under the NASA CRS Phase 2 contract splash down near Florida under parachutes in the Gulf of Mexico or the Atlantic Ocean.
NASA contracted for the CRS-23 mission from SpaceX and therefore determines the primary payload, date of launch, and orbital parameters for the Cargo Dragon.
The GITAI S1 Robotic Arm Tech Demo will test GITAI Japan Inc.'s microgravity robot by placing the arm inside the newly added Nanoracks Bishop Airlock, which was carried to the station by Dragon C208 during the SpaceX CRS-21 mission last year. Once inside the airlock, the arm will perform numerous tests to demonstrate its versatility and dexterity.
Designed by GITAI Japan Inc., the robot will work as a general-purpose helper under the pressurized environment inside the Bishop Airlock. It will operate tools and switches and run scientific experiments. The next step will be to test it outside the ISS in the harsh space environment. The robot will be able to perform tasks both autonomously and via teleoperations. Its arm has eight degrees of freedom and a 1-meter reach. GITAI S1 is a semi-autonomous/semi-teleoperated robotic arm designed to conduct specified tasks internally and externally on space stations, on-orbit servicing, and lunar base development. By combining autonomous control via AI and teleoperations via the specially designed GITAI manipulation system H1, GITAI S1 on its own, possesses the capability to conduct generous-purpose tasks (manipulation of switches, tools, soft objects; conducting science experiments and assembly; high-load operations; etc.) that were extremely difficult for industrial robots such as task specific robotic arms to do.
The new experiments arriving at the orbiting laboratory will inspire future scientists and explorers, and provide valuable insight for researchers.
