HOW TO PREPARE QUINOA SALAD ON BOARD THE ISS...

A great video via EarthSky:

ESA astronaut and Italian Air Force Captain Samantha Cristoforetti demonstrates how she prepares one of her favorite meals in microgravity, quinoa salad with tomato, mackerel and leek cream in a warm tortilla.




Video taken inside Unity, or Node 1. It's one of three nodes ("passive connecting modules") in the US Orbital Segment of the station. Launched in December 1998 as a cargo of the Endeavour Space Shuttle, it was the ISS's first US-built component. It's cylindrical in shape, with six berthing locations facilitating connections to other modules.

Some essential info on Unity via Gunter's Space Page:


"The Unity connecting module, technically referred to as Node 1, layed a foundation for all future U.S. International Space Station modules with six berthing ports, one on each side, to which future modules will be attached. Built by The Boeing Company at a manufacturing facility at the Marshall Space Flight Center in Huntsville, Alabama, Unity is the first of three such connecting modules that will be built for the station. Sometimes referred to as Node 1, the Unity module measures 15 feet in diameter and 18 feet long.

Carried to orbit aboard the Space Shuttle Endeavour, Unity was mated with the already orbiting Zarya control module, or Functional Cargo Block (Russian acronym FGB), a U.S.-funded and Russian-built component that will have been launched earlier aboard a Russian rocket from Kazakstan. In addition to connecting to the Zarya module, Unity eventually will provide attachment points for the U.S. laboratory module; Node 3; an early exterior framework, or truss for the station; an airlock; and a multi-windowed cupola.

Essential space station resources such as fluids, environmental control and life support systems, electrical and data systems are routed through Unity to supply work and living areas.

More than 50,000 mechanical items, 216 lines to carry fluids and gases, and 121 internal and external electrical cables using six miles of wire were installed in the Unity node. The detailed and complex hardware installation required more than 1,800 drawings. The node is made of aluminum.

Two conical docking adapters will be attached to each end of Unity prior to its launch aboard Endeavour. The adapters, called pressurized mating adapters (PMAs), allow the docking systems used by the Space Shuttle and by Russian modules to attach to the node's hatches and berthing mechanisms. One of the conical adapters will attach Unity to the Zarya, while the other will serve as a docking port for the Space Shuttle. The Unity node with the two mating adapters attached, the configuration it will be in for launch, is about 36 feet long and weighs about 25,600 pounds.

Attached to the exterior of one of the pressurized mating adapters are computers, or multiplexer-demultiplexers (MDMs), which will provide early command and control of the Unity node. Unity also will be outfitted with an early communications system that will allow data, voice and low data rate video with Mission Control, Houston, to supplement Russian communications systems during the early station assembly activities."
