Five Ways the International Space Station’s National Lab Enables Commercial Research

A growing number of commercial partners use the International Space Station National Lab. With that growth, we will see more discoveries in fundamental and applied research that could improve life on the ground.

Space Station astronaut Kate Rubins was the first person to sequence DNA in microgravity.

Since 2011, when we engaged the Center for the Advancement of Science in Space (CASIS) to manage the International Space Station (ISS) National Lab, CASIS has partnered with academic researchers, other government organizations, startups and major commercial companies to take advantage of the unique microgravity lab. Today, more than 50 percent of CASIS’ experiments on the station represent commercial research.

Here’s a look at five ways the ISS National Lab is enabling new opportunities for commercial research in space.

1. Supporting Commercial Life Sciences Research

One of the main areas of focus for us in the early origins of the space station program was life sciences, and it is still a major priority today. Studying the effects of microgravity on astronauts provides insight into human physiology, and how it evolves or erodes in space. CASIS took this knowledge and began robust outreach to the pharmaceutical community, which could now take advantage of the microgravity environment on the ISS National Lab to develop and enhance therapies for patients on Earth. Companies such as Merck, Eli Lilly & Company, and Novartis have sent several experiments to the station, including investigations aimed at studying diseases such as osteoporosis, and examining ways to enhance drug tablets for increased potency to help patients on Earth. These companies are trailblazers for many other life science companies that are looking at how the ISS National Lab can advance their research efforts.

2. Enabling Commercial Investigations in Material and Physical Sciences

Over the past few years, CASIS and the ISS National Lab also have seen a major push toward material and physical sciences research by companies interested in enhancing their products for consumers. Examples range from Proctor and Gamble’s investigation aimed at increasing the longevity of daily household products, to Milliken’s flame-retardant textile investigation to improve protective clothing for individuals in harm’s way, and companies looking to enhance materials for household appliances. Additionally, CASIS has been working with a variety of companies to improve remote sensing capabilities in order to better monitor our oceans, predict harmful algal blooms, and ultimately, to better understand our planet from a vantage point roughly 250 miles above Earth.

3. Supporting Startup Companies Interested in Microgravity Research 

CASIS has funded a variety of investigations with small startup companies (in particular through seed funding and grant funding from partnerships and funded solicitations) to leverage the ISS National Lab for both research and test-validation model experiments. CASIS and The Boeing Company recently partnered with MassChallenge, the largest startup accelerator in the world, to fund three startup companies to conduct microgravity research.

4. Enabling Validation of Low-Earth Orbit Business Models 

The ISS National Lab helps validate low-Earth orbit business models. Companies such as NanoRacks, Space Tango, Made In Space, Techshot, and Controlled Dynamics either have been funded by CASIS or have sent instruments to the ISS National Lab that the research community can use, and that open new channels for inquiry. This has allowed the companies that operate these facilities to validate their business models, while also building for the future beyond station.

5. Demonstrating the Commercial Value of Space-based Research

We have been a key partner in working with CASIS to demonstrate to American businesses the value of conducting research in space. Through outreach events such as our Destination Station, where representatives from the International Space Station Program Science Office and CASIS select cities with several major companies and meet with the companies to discuss how they could benefit from space-based research. Over the past few years, this outreach has proven to be a terrific example of building awareness on the benefits of microgravity research.

5 Fun Things To Do Without Gravity

Astronauts onboard the International Space station are typically active for at least 9 1/2 hours per day doing science, exercising and maintaining systems. Excluding scheduled time for sleep and lunch, astronauts have only 4 hours of free time during the work week, and that includes time for meals and general hygiene.

Even with a loaded calendar, the few who have such an opportunity to live in the microgravity environment find ways to make the most of this experience. Here are just a few of their favorite things about living in space: 

Flying

One of the most self-explanatory (and most fun!) aspects of living in space for the astronauts is “flying”. In space there is no up or down, so there is no floor or ceiling. There are rails throughout the space station that astronauts use to push themselves among the modules. 

Eating

Astronauts actually describe the food on the space station as quite tasty! In part, that’s because they have a large role in choosing their own meals. Over time though, a lot of astronauts experience desensitized taste buds from the shifting fluid to their head. Toward the end of their expedition, spicy foods tend to be their favorites because of this phenomenon.

Drinking

Liquid behaves very differently in space than it does on Earth. Astronauts cannot simply pour a cup of coffee into a mug. Without gravity, it would stick to the walls of the cup and would be very difficult to sip. Most of the time, astronauts fill a bag with liquid and use a special straw with a clamp to keep the contents from flying out. 

Playing Games

The space station crew occasionally gets downtime which they can spend however they please. Sometimes they watch a movie, read a book or take photos of Earth from the Cupola windows. Other times they invent games to play with each other, and each crew tends to come up with new games. Sometimes it can be hitting a target, flying from one end of the station to the other fastest or playing zero-gravity sports. 

Going Out For A Walk

Preparing and executing a spacewalk can take around 8 to 12 hours, and can be a jam-packed schedule. Spacewalkers have to be focused on the task at hand and sticking to the timeline. That said, they can still catch a spare moment to see the Earth 250 miles below. Many astronauts describe that view from a spacewalk as one of the most beautiful sights in their lives.
