Space Station Research: Nutrition

Each month, we highlight a different research topic on the International Space Station. In January, our focus is Nutrition. Understanding the role of nutrition in astronaut adaptation to spaceflight has a broader application on Earth. For example, understanding the relationship of nutrition to bone loss in space is potentially valuable for patients suffering from bone loss on Earth.

The space station is being utilized to study the risks to human health that are inherent in space exploration. The human body changes in various ways in microgravity, and nutrition-related investigations help us understand and reduce those risks associated with those changes. Examples are:

Bone mineral density loss

Muscle atrophy

Cardiovascular deconditioning

Immune dysfunction

Radiation

and more

Scientists can also test the effectiveness of potential countermeasures like exercise and nutrition, which can have health benefits for those of us on Earth.

Did you know that in 2015 the space station crew harvested and ate lettuce that was grown on the space station? The Veggie facility on station is an experiment that supports a variety of plant species that can be cultivated for educational outreach, fresh food and even recreation for crew members on long-duration missions. Right now, the crew is growing Zinnia flowers. Understanding how flowering plans grow in microgravity can be applied to growing other edible flowering plants, such as tomatoes.

We’re using our unique vantage point in space to provide observations and data of Hurricane Irma and other tropical storms. Hurricanes Irma and Jose are seen here in a 12-hour long infrared loop. Scientists monitor storms in infrared to closely monitor clouds and storm intensity. We continue to provide satellite imagery for these storms, tracking its trajectory, force and precipitation to inform forecasters at the National Hurricane Center.

As these storms continue their westward drive in the coming days, they will be passing over waters that are warmer than 30 degrees Celsius (86 degrees Fahrenheit)—hot enough to sustain a category 5 storm. Warm oceans, along with low wind shear, are two key ingredients that fuel and sustain hurricanes.

A new way to watch

This update brings you a whole new way to watch Vine.

Our latest design introduces a “Watch” button that lets you kick back and see the story of a channel as Vines automatically play back to back.

People love to go through a channel or watch an account from start to finish. You can now do that with just the tap of a button, without having to manually scroll through individual posts. Check out Johnny McHone and Alona Forsythe for a couple examples.

When you’re on a user’s channel, you can tap “Posts” to choose how you want to view Vines: oldest to newest, newest to oldest, or by what’s popular. We recently introduced these options, and we recommend using them with this new viewing experience. Also, if you want to make a Vine loop as you’re watching, tap and hold it.

Get the update now on the App Store or Google Play.

The NASA Village… A Passion for Space Pushes Limits

SHAKE IT UP! The Orion Exploration Mission-1 crew module was blasted with 141 decibels of acoustic energy to make sure parts don’t come loose when exposed to extreme vibrations experienced at launch. Don’t try this at home.  

Here is the flight path trajectory (in yellow), that I took in order to rescue myself using the virtual reality view of the ISS and software generated SAFER (gaseous nitrogen “jet” pack) to “fly” myself back to structure. Orbital mechanics can be extremely difficult to predict if you do not try to fly back on the same trajectory that you “fell” off on.
