Posted: October 3, 2012

NOTE: On its first operational resupply flight to the International Space Station, the Dragon spacecraft will launch with 882 pounds of crew supplies, experiments and spare parts. The capsule will return to Earth with approximately 1,673 pounds of equipment from the space station.

Return Cargo 1,673 pounds (1,995 pounds w/ packaging)
Crew supplies (163 pounds)
  • Crew preference items

  • Official flight kit items

  • ESA PAO items

  • Flight crew equipment
Utilization payloads (866 pounds for NASA, ESA, JAXA)
  • Double Cold Bags - Five cold bags used to refrigerate samples for transport.

  • UMS - Urine Monitoring System (UMS) is designed to collect an individual urine void, gently separate liquid from air, accurately measure the liquid volume of the urine, allow sample packaging, and discharge remaining urine into the Waste and Hygiene Compartment (WHC).

  • MELFI EU - Electronics unit for Minus Eighty-degree Laboratory Freezer for ISS (MELFI), an ultra-cold storage unit for experiment samples.

  • GLACIER - General Laboratory Active Cryogenic ISS Experiment Refrigerator

  • BioLab - Biological Experiment Laboratory in Columbus (BioLab) is a multiuser research facility located in the European Columbus laboratory. It will be used to perform space biology experiments on microorganisms, cells, tissue cultures, small plants, and small invertebrates.

  • Energy - Astronaut's Energy Requirements for Long-Term Space Flight (Energy) wil measures changes in energy balance in crew members.

  • CSPINS - Dynamism of Auxin Efflux Facilitators, CsPINs, Responsible for Gravity-regulated Growth and Development in Cucumber (CsPINs) uses cucumber seedlings to analyze the effect of gravity on gravimorphogenesis (peg formation) in cucumber plants.

  • Hicari - Materials science investigation Growth of Homogeneous SiGe Crystals in Microgravity by the TLZ Method (Hicari) aims to verify crystal-growth by traveling liquidous zone method, and to produce high-quality crystals of silicon-germanium (SiGe) semiconductor using the Japanese Experiment Module-Gradient Heating Furnace (JEM-GHF).

  • Marangoni - Marangoni convection is the flow driven by the presence of a surface tension gradient which can be produced by temperature difference at a liquid/gas interface.

  • Resist Tubule - Role of Microtubule-Membrane-Cell Wall Continuum in Gravity Resistance in Plants (Resist Wall) investigation was conducted to determine the importance of the structural connections between microtubules, plasma membrane, and the cell wall as the mechanism of gravity resistance.

  • MICROBE III - Microbe-III experiment monitors microbes on board the ISS which may affect the health of crew members.

  • MYCO - Mycological evaluation of crew exposure to ISS ambient air (Myco) evaluates the risk of microorganisms via inhalation and adhesion to the skin to determine which fungi act as allergens.

  • IPU Power Supply Module - Image Processing Unit (IPU) is a Japan Aerospace Exploration Agency (JAXA) subrack facility that receives, records, and downlinks experiment image data for experiment processing.
