Mission or Study ID:   SpaceX_5
International Space Station (ISS)
Launch/Start Date:
Landing/End Date:
32 days

The Dragon spacecraft carried more than 5,000 pounds of supplies and payloads, including critical materials to support 256 science and research investigations occurring during Expeditions 42 and 43. Science payloads include model organism research using fruit flies and flatworms to better understand wound healing in space. A special science payload is the Cloud-Aerosol Transport System which will monitor cloud and aerosol coverage which directly impacts global climate. The mission also delivered an IMAX camera for filming during four increments and tools to be used in future EVA’s to prepare the station for the installation of the new international docking adapters. After four weeks at the space station, the spacecraft returned with more than 3,600 pounds of cargo, including crew supplies, hardware and computer resources, science experiments, space station hardware, and trash.

Research Highlights:
Fruit Fly Lab
The common fruit fly (Drosophila melanogaster) is an important animal model for the human immune system, making it a useful model for studying the biological effects of spaceflight. Spaceflight affects the innate immune system, which could make animals including humans more susceptible to disease, especially because microbes can become more virulent in space. The NASA Ames Research Center (ARC) ISS Drosophila Experiment (Fruit Fly Lab-01) studies the combined effect of altered host immunity with changes to microbes in space.

The investigation of interactions between the host and bacteria, conserved cellular responses, and countermeasure efficacy during spaceflight using the human surrogate model Caenorhabditis elegans (Micro-5) aims to better understand the risks of in-flight infections in space explorers during long-term space flight, using the model organism Caenorhabditis elegans (roundworm) with the microbe Salmonella typhimurium (that causes food poisoning in humans).

ISS Microbial Observatory (Microbial Tracking-1)
A three-part investigation that seeks to characterize airborne and surface-associated populations of microorganisms aboard the International Space Station. Conducting three separate sampling missions will allow the investigators to assess how the microbial communities aboard the station change over time. The three parts of the investigation are planned to fly to the station aboard SpaceX-5, SpaceX-6, and SpaceX-7.
