SpaceX Dragon capsule is unloading today – what did it bring to the ISS?

SpaceX Dragon

The 18-foot tall SpaceX Dragon cargo capsule is reportedly dropping off its goods at the International Space Station today, after having docked there last week, but what did it bring? The load of gear, food, and other essentials that NASA paid the private company to transport to the space station weighed in at a total of 1014 pounds, so we know it was more than just dehydrated ice cream and season two of Game of Thrones.

Out of the total shipped weight 674 pounds of it was made up of “food and crew provisions” which includes necessities, like 162 meals worth of food and batteries, but also clothing and “pantry items”. It was said that no mission critical items were sent aboard the Dragon capsule.

The full manifest is available here (PDF), highlights of the 1146 pound of gear being brought to the ISS include:

  • 13 bags standard rations
  • 5 bags low sodium rations
  • SODF and official flight kit
  • NanoRacks Module 9 for U.S. National Laboratory
  • Ice bricks cargo bags
  • Laptop, batteries, power supply cables

The list is quite interesting if you dig into it. For example about 60% of the goods were necessities — food, clothing, batteries, etc. Apparently none of that was water, at least at first glance. NASA did send up bricks of ice to keep experimental samples cool on the trip, as opposed to actively cooling them — maybe that water is potable (after being filtered)? Also sent up was the “SODF”, which seems to be the Systems (or Station) Operation Data File and a laptop. The combined weight of the laptop, batteries, and cables was 22 pounds… must be a lot of batteries or a very large ThinkPad.

The crew is also sending back a fair bit of material, 1455 pounds in fact. That gear includes:

  • NanoRacks-CubeLabs Module-9 range from microbial growth to water purification in microgravity
  • “Plant Signaling” hardware
  • Shear History Extensional Rheology Experiment (SHERE) Hardware
  • Cargo bags
  • Multifiltration Bed
  • Iodine Compatible Water Containers

The manifest includes all the weights, in case you are curious how the mission’s controllers chose to divide up the amount that they could carry.
