The CRS-34 Dragon is set to lift off at 7:16 p.m. EDT on 12 May from Cape Canaveral, carrying a wood-based bone scaffold and other experiments.
It is due to dock autonomously with the station's Harmony module on 14 May, bringing studies on microgravity simulation, red blood cells and charged particles affecting power grids and satellites.
Dragon is expected to stay until mid-June before returning completed experiments and time-sensitive cargo to Earth, supporting ongoing ISS crew operations and research in low Earth orbit.
As the ISS nears retirement, is NASA's new plan for a core module a lifeline or a setback for commercial space stations?
With the ISS decommissioning by 2030, will private industry be ready in time to prevent a U.S. gap in low Earth orbit?
Can experiments on wood-based scaffolds and planet formation secure humanity's future in space before the ISS is gone?
