Space Food Processing and Packaging

Space foods are processed to ensure quality and safety. Fresh fruits and vegetables are minimally processed they’re sanitized with a 200 parts per million (ppm) chlorine rinse, air dried and then placed on a food tray, ready to be stored in the fresh food locker. Some vegetables, like carrots and celery, are packaged in sealable bags. All fresh foods need to be eaten within the first few days of a mission because they spoil quickly.

NASA scientists use certain processing techniques to make foods shelf stable, or safe to store at room temperature. Thermostabilization, or heat processing, extends shelf life to three years. Irradiated foods are shelf stable because they’re sterilized by a dose of ionizing radiation. Lowering the pH and water activity of foods can also stabilize them. Freeze drying, or removing water from foods, inhibits microbial growth, and mold growth can be prevented by removing oxygen from packaging.

Shelf life is determined by noting changes in product quality, and the lab has specific methodology for testing. All foods intended for shuttle flights must have nine month minimum shelf lif mulberry sale e. Foods going to the International Space Station must have a one year shelf life, and any foods developed for future planetary expeditions or outposts must have a five year shelf life [source: Iowa State University].

Testing at the Space Food Systems Laboratory begins with sensory evaluations. Astronauts rate food by appearance, color, odor, flavor, texture and overall palatability. Foods are then exposed to time and temperature changes, and sensor mulberry sale y evaluations are repeated to determine how the foods hold up.

Scientists perform chemical analyses by testing the food’s moisture, pH, water activity, nutrients, color and texture as well as considering time and temperature changes.

Packaging materials and methods are developed to reduce contaminates. The materials’ weight, shape and waste are also considered during development. Currently, scientists take advantage of materials such as Mylar, Aclar and polyethylene to create flexible mulberry sale containers and pouches as well as sticking to old standards like foil pouches and aluminum for cans.

Since food weight allowance is limited to 3.8 lbs (1.7 kl) per person, per day on the ISS, and only 0.5 lbs (0.23 kl) per person, per day on the shuttle, the lab continues to develop new packaging materials to reduce weight and waste [sources: NASA and Iowa State University].

Each package is given a barcode and colored fabric fastener dots. The dots’ colors match each crewmember with his or her menu items. Astronauts use the barcodes to log each food item when consumed information used by the lab back home in determining future food lists.

Once products and menus are green lighted, they’re given to the Flight Equipment Processing Contractor for processing, packaging and storing before being sent to Kennedy Space Center (KSC) in Florida. Two to three days before launch (or 24 hours for fresh foods), food lockers are placed onboard the shuttle, ready to go into space.

The Vomit Comet

Scientists at the Space Food Systems Laboratory study the effects of microgravity on the appearance and packaging of foods. They take these effects into consideration when developing new product packaging, food selection and in flight systems. People and objects “float” in microgravity because the effects of gravity are reduced in space. For this reason, scientists have had to develop straws with clamps to prevent liquids from escaping accidentally as well as magnetized utensils that stay attached to food trays. In Houston, NASA keeps a KC 135 airplane, nicknamed the “Vomit Comet,” where scientists test products and prototypes in a simulated microgravity environment.

NASA tracks around 20,000 pieces of larger (5cm+) orbital debris, but there an estim mulberry sale ated 500,000 pieces of marble sized, untrackable debris in orbit as well. If a single piece of space junk hits an orbiting, functional spacecraft, the collision is likely to be catastrophic just like in the movie Gravity. If we don get on top of orbital debris now, it feared that one day the junk will be so dense that we won be able to leave the surface of Earth without being smashed to pieces.

Declaring war on orbital space debris October 26, 2012 at 6:59 amOnce something gets into the Earth orbit it tends to stay there, even after its useful life has ended. That has led to the collection of vast amounts of space junk surrounding our planet an mulberry sale d more than a few headaches for anyone tasked with launching or maintaining a satellite.

Right now there are 19,000 dead satellites and other pieces of space debris hurtling around the planet at the speed of a bullet. DARPA has proposed a Frankenstein robotic satellite to help all mulberry sale eviate the problem.

Space Bags

Space Bag Product ReviewSpace Bags Vacuum Storage BagsSpace Bags have been around for years and the reason they have been around for years is because Space Bags work!

The image below shows six comfortors and blankets air sealed in Space Bags mulberry sale .

Space Bags are affordable, durable, long lasting and help you increase your storage space. Space Bags fit under beds, coaches, dresser draws kitchen and bathroom cabinets and of course top, sides or bottom of clothing closets. The bags come in many different sizes to fit your needs but the size bags I speak of in this Space Bag product review are the travel size, small, medium and large size bags. They are pe mulberry sale rfect to use when rotating clothing for seasonal use. Store your Spring and Summer clothing in Space Bags to keep them safe while storing them away in a small designated area so you can have your closet space filled with your Fall and Winter clothing. When Spring and Summer come around, store your Fall and Winter clothing in the vacu sealed bags so you open your closet space to use for your Spring and Summer clothing. Rotation is key when people live in limited spaced areas. Using vacu sealed storage bags not only help increase your living space but help you see exactly what you own and have instead of buying more clothing that you probably don’t need. Think about it, if you rotated your clothing about every six months, you would know exactly what you have mulberry sale available to wear. This might sound like a no brainer but how many times have you bought a piece of clothing that you realized weeks later you did not need YET?Space Bags are not only used by people who want to increase their storage space. People use them to store away materials in their basements or garages and they do so because Space Bags protect materials from different weather conditions. They help protect material from moisture and air that can’t cause mold and odors. I ripped one large Space Bag while storing it in a top closet shelf. I have wire shelving and there was a tiny piece of wire sticking out mulberry sale and at first I did not see it and the bag ripped and once ripped the vacu Space Bag is useless. The full size comforter folded in the vacu sealed bag starts about 12 inches and when I vacu sealant the comforter flattens into about 2 inches.
