Thanksgiving...in Space

Since 2000, humans have continuously lived and worked on the International Space Station. That means plenty of crew members have celebrated holidays off the Earth.

Although they’re observing the same holidays, they do so in a slightly different way because of the unique environment 250 miles above the Earth.

Consider the differences of living on Earth and in space…

Food scientists must develop foods that will be easier to handle and consume in an environment without gravity. The food must not require refrigeration and also provide the nutrition humans need to remain healthy.

Freeze drying food allows it to remain stable at room temperature, while also significantly reducing its weight.

Did you know that all the food sent to the space station is precooked? Sending precooked food means that it requires no refrigeration and is either ready to eat or can be prepared by simply adding water or by heating. 

The only exception are the fruit and vegetables stowed in the fresh food locker. The food comes in either freeze-dried containers or thermostabilized pouches. If freeze-dried in a vacuum sealed package, the astronauts have a rehydration system in-flight, which they use restore moisture in their food.  If thermostabilized, the packaging is designed to preserve the food similar to canned products, but instead in a flexible, multi-layered pouch.

So what will the space station crew eat this year (2016) for Thanksgiving?

Turkey

Cherry/Blueberry Cobbler

Candied Yams

Rehydratable Cornbread Dressing

Rehydratable Green Beans and Mushrooms

Rehydratable Mashed Potatoes

What are you bringing to Thanksgiving on Earth this year? Treat your family and friends astronaut-style with this cornbread dressing recipe straight out of our Space Food Systems Laboratory…no freeze drying required!

For spaceflight preparation:

Baked dressing is transferred to metal tray and freeze-dried accordingly. One serving of cornbread dressing shall weigh approximately 145 g prior to freeze-drying and 50 g after freeze-drying.

Happy Thanksgiving!

SpaceX Lands the Falcon9 First Stage - A revolution in Rocket Science and Engineering

Today, at 8:33, Spacex made history. They landed the first stage of their Falcon9 rocket after having it successfully deploy a second stage into low earth orbit.

The Video is here:

Unlike other rocket companies, Spacex in not making small hops - they did that 2 years ago with their grasshopper rocket. In fact, this is how they tested the initial avionics systems that would be able to land the rocket in a stable position autonomously. Here is some footage:

Unlike the companies that make these hops, Spacex has to use this stage to help get payloads into low earth orbit… and then recover it! This is incredibly difficult and requires an advanced retro-thrusting maneuver that has never been successful - until now! The diagram below shows this thrusting maneuver, which happens shortly after the second stage has decoupled and ignited.

Spacex claims that this is similar to throwing a pencil over the Empire State Building, then having it flip perfectly, then haveing it fall into a shoebox… easy enough right?

Only, in real life SpaceX isn’t shooting a pencil… they are shooting a rocket! This is the pad that the now famous falcon9 rocket landed on:

Now you might ask, why does this matter? This means space will become cheaper! We can already build satellites that are less than $10,000, as a matter of fact I’m building a small satellite with a team right now! As it currently stands, space travel is too expensive for creative people to take risks. Now, thanks to SpaceX, we may be mining or visiting asteroids, visiting the moon, visiting mars, or doing something crazier - and we may be doing this very soon! The Falcon9 rocket costs $54 million to build but only $200,000 to refuel… let’s put this in perspective… That’s the same amount that it costs to refuel a Boeing 747 (which is the airplane that consumers use to fly around the world). This means that space travel could be as cheap as air travel very soon! Way to go SpaceX!
