SpaceX plans to reuse each Cargo Dragon up to five times. Cargo Dragon does not includeSuperDraco abort engines, seats, cockpit controls or life support system needed on a Crew Dragon.[4][5]Dragon 2 improves onDragon 1 in several ways, including lessened refurbishment time, leading to shorter periods between flights.[6]
Cargo Dragon capsules under the NASA CRS Phase 2 contract land nearFlorida in the ocean.[4][6]
NASA contracted for the CRS-26 mission from SpaceX and therefore determines the primary payload, date of launch, andorbital parameters for theCargo Dragon.[7]
Second pair of new solar arrays using XTJ Prime space solar cells. They were delivered to the station in the unpressurized trunk of the Cargo Dragon spacecraft.[8]
The installation of these new solar arrays, designated 4A and 3A, required two spacewalks: one to prepare the worksite with a modification kit and another to install the new panel.[8][9]
European Space Agency (ESA) research and activities:
ESA'sSuture in Space experiment investigating how tissues heal in weightlessness. Living tissue from biopsies will be cut and sewn back together, before being sent to space where astronauts will activate the cells to monitor the healing mechanisms.[[11]]
ESA'sOsteogenic Cells experiment which aims to investigate the mechanisms of impaired bone formation during space flight and whether microgravity conditions alter osteoblast function in vitro.
As part of the research payload, the Artery in Microgravity[1] experiment from the ESA Orbit Your Thesis programme[2] will be installed inside the ICE Cubes Facility[3].
MARIO (Measurement of Actuator Response and Impedance on Orbit) is a 3U CubeSat collaboration between theUniversity of Michigan's Michigan eXploration Laboratory (MXL), Extreme Diagnostics, and Michigan's Active Intelligent and Multifunctional Structure (AIMS) Lab, andNASA. The mission objective is to characterize the performance of piezoelectric actuators and health monitoring systems in low Earth orbit conditions. Test data will help develop future advanced space mechanisms.
NUTSat is a 2U CubeSat for systems engineering training and commercial aircraft safety technology demonstration mission, fromNFU, Let'scom,Gran Systems and NSPO.
LORIS (Low Orbit Reconnaissance Imagery Satellite) from Dalhousie University, will be the first CubeSat from Atlantic Canada to be launched by the Canadian Space Agency. The mission objective is to obtain photographs via the camera payload, which will be used to study and monitor shorelines and ocean life activity.[4]
