The last Block 4 Falcon 9 flew yesterday, boosting an unmanned Dragon capsule to the ISS for the CRS-15 mission (skip to about 18:50 for the launch):
Since this was the final Block 4 flight, SpaceX did not attempt to recover the booster. This was, however, its second flight; Core 1045 helped launch the TESS satellite on April 18, which is just a 72 day turnaround to its second flight, SpaceX’s fastest reflight to date.
Unpressurized cargo includes the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) for JPL and a replacement latching end effector for the SSRMS. Pressurized cargo includes:
- Chemical Gardens (a crystal growth experiment)
- an experimental carbon fiber “factory” for the private company Made In Space (the third one flown to date)
- Crew Interactive Mobile (CIMON), a floating spherical robot trained to recognize and interact with European crewmember Alexander Gerst.
- Rodent Research 7, which will study microorganisms in the guts of a colony of “mouseonauts”
- BCAT-CS, a sediment research project
- Three Cubesats called Biarri-Squad for a multinational experiment to study potential military applications for smallsats (these will be experimenting with laser rangefinding and GPS to maintain relative position data)
- Three CubeSats from the Japanese-led multinational Birds-2 project performing a range of technology demonstrator experiments
- One of the Birds-2 CubeSats is Bhutan-1 (aka Bird BTN), the Kingdom of Bhutan’s first satellite
- Another is Bird PHL or Maya-1, the first Filipino CubeSat (not their first satellite
