15 Ways the International Space Station is Benefiting Earth

With astronauts living and working aboard the International Space Station, we’re learning a great deal about creating and testing critical systems, maintaining efficient communications and protecting the human body during a deep space mission. While these are critical to our journey to Mars, it is important to also note all the ways in which research conducted and technology tested aboard the orbiting laboratory help us here on Earth.

Here are 15 ways the space station is benefiting life on Earth:

1. Commercializing Low-Earth Orbit

An exciting new commercial pathway is revolutionizing and opening access to space, fostering America’s new space economy in low-Earth orbit. For the first time, the market is expressing what research can and should be done aboard the microgravity laboratory without direct government funding. Our move to purchase commercial cargo resupply and crew transportation to the space station enables U.S. businesses to develop a competitive capability they also can sell as a service to others while freeing our resources for deep space exploration. Private sector participation provides a new model for moving forward in partnership with the government.

2. Supporting Water Purification Efforts Worldwide

Whether in the confines of the International Space Station or a tiny hut village in sub-Saharan Africa, drinkable water is vital for human survival. Unfortunately, many people around the world lack access to clean water. Using technology developed for the space station, at-risk areas can gain access to advanced water filtration and purification systems, making a life-saving difference in these communities. The Water Security Corporation, in collaboration with other organizations, has deployed systems using NASA water-processing technology around the world.

3. Growing High-Quality Protein Crystals

There are more than 100,000 proteins in the human body and as many as 10 billion in nature. Every structure is different, and each protein holds important information related to our health and to the global environment. The perfect environment in which to study these structures is space. Microgravity allows for optimal growth of the unique and complicated crystal structures of proteins leading to the development of medical treatments. An example of a protein that was successfully crystallized in space is hematopoietic prostaglandin D synthase (H-PGDS), which may hold the key to developing useful drugs for treating muscular dystrophy. This particular experiment is an example of how understanding a protein’s structure can lead to better drug designs. Further research is ongoing.

4. Bringing Space Station Ultrasound to the Ends of the Earth

Fast, efficient and readily available medical attention is key to survival in a health emergency. For those without medical facilities within easy reach, it can mean the difference between life and death. For astronauts in orbit about 250 miles above Earth aboard the International Space Station, that problem was addressed through the Advanced Diagnostic Ultrasound in Microgravity (ADUM) investigation. Medical care has become more accessible in remote regions by use of small ultrasound units, tele-medicine, and remote guidance techniques, just like those used for people living aboard the space station.

5. Improving Eye Surgery with Space Hardware

Laser surgery to correct eyesight is a common practice, and technology developed for use in space is now commonly used on Earth to track a patient’s eye and precisely direct the laser scalpel. The Eye Tracking Device experiment gave researchers insight into how humans’ frames of reference, balance and the overall control of eye movement are affected by weightlessness. In parallel with its use on the space station, the engineers realized the device had potential for applications on Earth. Tracking the eye’s position without interfering with the surgeon’s work is essential in laser surgery. The space technology proved ideal, and the Eye Tracking Device equipment is now being used in a large proportion of corrective laser surgeries throughout the world.

6. Making Inoperable Tumors Operable with a Robotic Arm

The delicate touch that successfully removed an egg-shaped tumor from Paige Nickason’s brain got a helping hand from a world-renowned arm—a robotic arm, that is. The technology that went into developing neuroArm, the world’s first robot capable of performing surgery inside magnetic resonance machines, was born of the Canadarm (developed in collaboration with engineers at MacDonald, Dettwiler, and Associates, Ltd. [MDA] for the U.S. Space Shuttle Program) as well as Canadarm2 and Dextre, the Canadian Space Agency’s family of space robots performing the heavy lifting and maintenance aboard the International Space Station. Since Nickason’s surgery in 2008, neuroArm has been used in initial clinical experience with 35 patients who were otherwise inoperable.

7. Preventing Bone Loss Through Diet and Exercise

In the early days of the space station, astronauts were losing about one-and-a-half percent of their total bone mass density per month. Researchers discovered an opportunity to identify the mechanisms that control bones at a cellular level. These scientists discovered that high-intensity resistive exercise, dietary supplementation for vitamin D and specific caloric intake can remedy loss of bone mass in space. The research also is applicable to vulnerable populations on Earth, like older adults, and is important for continuous crew member residency aboard the space station and for deep space exploration to an asteroid placed in lunar orbit and on the journey to Mars.

8. Understanding the Mechanisms of Osteoporosis

While most people will never experience life in space, the benefits of studying bone and muscle loss aboard the station has the potential to touch lives here on the ground. Model organisms are non-human species with characteristics that allow them easily to be reproduced and studied in a laboratory. Scientists conducted a study of mice in orbit to understand mechanisms of osteoporosis. This research led to availability of a pharmaceutical on Earth called Prolia® to treat people with osteoporosis, a direct benefit of pharmaceutical companies using the spaceflight opportunity available via the national lab to improve health on Earth.

9. Developing Improved Vaccines

Ground research indicated that certain bacteria, in particular Salmonella, might become more pathogenic (more able to cause disease) during spaceflight. Salmonella infections result in thousands of hospitalizations and hundreds of deaths annually in the United States. While studying them in space, scientists found a pathway for bacterial pathogens to become virulent. Researchers identified the genetic pathway activating in Salmonella bacteria, allowing the increased likelihood to spread in microgravity. This research on the space station led to new studies of microbial vaccine development.

10. Providing Students Opportunities to Conduct Their Own Science in Space

From the YouTube Space Lab competition, the Student Spaceflight Experiments Program, and SPHERES Zero Robotics, space station educational activities inspire more than 43 million students across the globe. These tyFrom the YouTube Space Lab competition, the Student Spaceflight Experiments Program, and SPHERES Zero Robotics, space station educational activities inspire more than 43 million students across the globe. These types of inquiry-based projects allow students to be involved in human space exploration with the goal of stimulating their studies of science, technology, engineering and mathematics. It is understood that when students test a hypothesis on their own or compare work in a lab to what’s going on aboard the space station, they are more motivated towards math and science.

11. Breast Cancer Detection and Treatment Technology

A surgical instrument inspired by the Canadian Space Agency’s heavy-lifting and maneuvering robotic arms on the space station is in clinical trials for use in patients with breast cancer. The Image-Guided Autonomous Robot (IGAR) works inside an MRI machine to help accurately identify the size and location of a tumor. Using IGAR, surgeons also will be able to perform highly dexterous, precise movements during biopsies.

12. Monitoring Water Quality from Space

Though it completed its mission in 2015, the Hyperspectral Imager for the Coastal Ocean (HICO) was an imaging sensor that helped detect water quality parameters such as water clarity, phytoplankton concentrations, light absorption and the distribution of cyanobacteria. HICO was first designed and built by the U.S. Naval Research Laboratory for the Office of Naval Research to assess water quality in the coastal ocean. Researchers at the U.S. Environmental Protection Agency (EPA) took the data from HICO and developed a smartphone application to help determine hazardous concentrations of contaminants in water. With the space station’s regular addition of new instruments to provide a continuous platform for Earth observation, researchers will continue to build proactive environmental protection applications that benefit all life on Earth.

13. Monitoring Natural Disasters from Space

An imaging system aboard the station, ISS SERVIR Environmental Research and Visualization System (ISERV), captured photographs of Earth from space for use in developing countries affected by natural disasters. A broader joint endeavor by NASA and the U.S. Agency for International Development, known as SERVIR, works with developing nations around the world to use satellites for environmental decision-making. Images from orbit can help with rapid response efforts to floods, fires, volcanic eruptions, deforestation, harmful algal blooms and other types of natural events. Since the station passes over more than 90 percent of the Earth’s populated areas every 24 hours, the ISERV system was available to provide imagery to developing nations quickly, collecting up to 1,000 images per day. Though ISERV successfully completed its mission, the space station continues to prove to be a valuable platform for Earth observation during times of disaster.

14. Describing the Behavior of Fluids to Improve Medical Devices

Capillary Flow Experiments (CFE) aboard the space station study the movement of a liquid along surfaces, similar to the way fluid wicks along a paper towel. These investigations produce space-based models that describe fluid behavior in microgravity, which has led to a new medical testing device on Earth. This new device could improve diagnosis of HIV/AIDS in remote areas, thanks in part to knowledge gained from the experiments.

15. Improving Indoor Air Quality

Solutions for growing crops in space now translates to solutions for mold prevention in wine cellars, homes and medical facilities, as well as other industries around the world. NASA is studying crop growth aboard the space station to develop the capability for astronauts to grow their own food as part of the agency’s journey to Mars. Scientists working on this investigation noticed that a buildup of a naturally-occurring plant hormone called ethylene was destroying plants within the confined plant growth chambers. Researchers developed and successfully tested an ethylene removal system in space, called Advanced Astroculture (ADVASC). It helped to keep the plants alive by removing viruses, bacteria and mold from the plant growth chamber. Scientists adapted the ADVASC system for use in air purification. Now this technology is used to prolong the shelf-life of fruits and vegetables in the grocery store, and winemakers are using it in their storage cellars.

This Week @ NASA

Astronauts conduct a spacewalk on the International Space Station to prepare it for future activities. Peggy Whitson became the new women’s record holder for number of spacewalks and more!

International Space Station

Work continued aboard the International Space Station. Spacewalkers Shane Kimbrough and Peggy Whitson used the station’s robotic arm to move the Pressurized Mating Adapter-3 on March 24 to move a module to accommodate U.S. commercial spacecraft carrying astronauts on future missions. They continued this work on March 30. Another spacewalk to complete the work is slated for April.

James Webb Space Telescope

Engineers at our Goddard Space Flight Center Center complete vibration and acoustic tesing on the James Webb Space Telescope, which was subjected to earsplitting noice and shaken 50-100 times per second to simulate the rigors of launch.

MAVEN

Data from our MAVEN, our Mars Atmosphere and Volatile EvolutioN, and published in the journal Science, concludes that solar wind and radiation are responsible for stripping Mars of its atmosphere and turning it into the frigid desert world it is today.

Most of the gas ever in the Red Planet’s atmosphere has been lost to space. The MAVEN team focused on the gas argon, estimating that 65% of it has been stripped from the planet. In 2015, the science team determined that atmospheric gas continues to be lost to space.

The International Space Station: Apex of International Collaboration

It's National Space Day! To mark the occasion, we're reflecting on the International Space Station, which has been continuously occupied since Nov. 2, 2000. As our orbiting laboratory that enables us to conduct important science off our home planet, the ISS allows researchers from all over the world to put their talents to work on innovative experiments in the microgravity environment. An international partnership of space agencies provides and operates the elements of the ISS. The principals are the space agencies of the United States, Russia, Europe, Japan and Canada. Although each space station partner has distinct agency goals for station research, each partner shares a unified goal to extend the resulting knowledge for the betterment of humanity! Here are 5 fun facts about our about our out-of-this world floating laboratory:

1. The ISS is a unique scientific platform that has enabled more than 3,600 researchers in 106 countries and areas to conduct more than 2,500 experiments in microgravity through February 2018—and the research continues. 

2. Astronauts and cosmonauts have conducted more than 205 spacewalks (and counting!) for space station construction, maintenance and repair since December 1998.

3. The station’s orbital path takes it over 90 percent of the Earth’s population, with astronauts taking millions of images of the planet below. 

4. Six spaceships can be connected to the space station at once.

5. An international crew of at most six people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes.

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph.

Where Will We Land On Mars?

What?

You’ve heard us say that we’re on a journey to Mars, but the Red Planet is big. Once we get there, where will we land the first humans? We’re holding the first Landing Sites/Exploration Zones Workshop for Human Missions to the Surface of Mars to figure it out. This first workshop was held Oct. 27-30, 2015 at the Lunar and Planetary Institute in Houston.

Why?

The goal of this workshop was to collect proposals for locations on Mars that would be of high scientific research value while also providing natural resources to enable explorers to land, live and work safely on the Red Planet. Determining where we will land humans on Mars is a multi-year process. There was around 45 proposal teams at the workshop. This was the first of many workshops to determine the best landing site for human exploration on Mars.

Why Now?

We plan to use existing assets at Mars, such as the Mars Reconnaissance Orbiter (MRO) and the Odyssey spacecraft, to support the selection process of potential Exploration Zones. However, the life expectancy of MRO and Odyssey are limited. We are eager to take advantage of the remaining operational years of those Martian images to gather high resolution maps of potential Exploration Zones while the spacecraft remain operational.

Stay Updated

The workshop will be aired live USTREAM starting at 2 p.m. EDT Tuesday, Oct. 27.

This blog post will also be updated daily with a recap from the workshop’s events.

For a full schedule of the event visit: http://www.hou.usra.edu/meetings/explorationzone2015/pdf/program.pdf

Day 1 Recap:

"There is no such thing as robotic exploration. All exploration is human exploration — the robot is just a tool.” - John Grunsfeld, NASA Associate Administrator for the Science Mission Directorate

Day one of the workshop answered a lot of basic questions about why looking at landing sites now is important for the future of our journey to Mars.

Attendees heard from many presenters, including Ellen Ochoa, Director of Johnson Space Center and John Grunsfeld, Associate Administrator of NASA’s Science Mission Directorate.

Experts explained that in order to leverage our current assets at Mars and start the process of picking possible landing sites, we need to start the discussion now.

This data will Inform our efforts to define what we need as far as future reconnaissance capabilities at Mars and drive where we send robotic landers to get ground truth.

Check back tomorrow for the day two update, and watch live on USTREAM starting at 9 a.m. EDT.

BONUS: Have questions about potential landing sites on Mars? We’ll be hosting a live social Q&A tomorrow at 7 p.m. EDT. Two NASA experts and one 15-year old student on one of the proposal teams will be answering your questions. Tune in on USTREAM and use #askNASA.

Day 2 Recap:

The second day of the Mars Landing Sites Workshop was filled with presentations from various proposal groups. Contributors made cases for where the best science could be collected on the Martian surface.

We also had the opportunity to hear from a young presenter, Alex Longo. A 15-year old student from Raleigh, N.C.

Longo also joined us for the social Q&A where we answered questions from #askNASA. He, along with two NASA experts, fielded questions that ranged from specifics about the workshop, to chatting aboutMars mysteries.

Tune in tomorrow to watch more of the presentations and see potential Mars landing sites! Watch live on USTREAM starting at 9 a.m. EDT.

Check back tomorrow for the day three update.

Day 3 Recap:

The third day of the workshop included presentations from the remaining proposal teams. This final day of presentations will lead into the last day of the workshop, when groups will discuss all of the ideas shared during the past week.

The day got really exciting when our Space Exploration Vehicle (SEV) made an appearance. This SEV concept is designed to be flexible, depending on the exploration destination. The pressurized cabin can be used for surface exploration of planetary bodies, including near-Earth asteroids and Mars.

Tomorrow is the final day of the workshop and will include group discussions. Participants will have the chance to assess the proposed sites and talk about the future steps needed for selecting a potential human landing site for our journey to Mars.

Watch these discussions live on USTREAM starting at 9 a.m. EDT.

Final Day Recap:

The final day of our workshop on potential Mars landing sites included discussions on the presentations that were made throughout the week.

Participants also had the opportunity to hear from NASA experts like Jim Green, director of planetary science, about future exploration and our journey to Mars.

Video of the full workshop will be available on the Lunar Planetary Institute’s YouTube channel. For more information and updates on our journey to Mars, visit HERE.

1. All Grown Up

After exceeding her 90-day mission and design parameters many times over, our plucky little rover Opportunity turns 13 years old on the Red Planet. She’s officially a teenager!

2. People’s Space

The public contributes so much wonderful art that we decided to make a place to share it. Enjoy!

3. Ready for a Close Up

Our Juno spacecraft recently got a closer look at Jupiter’s Little Red Spot. The craft’s JunoCam imager snapped this shot of Jupiter's northern latitudes on December 2016, as the spacecraft performed a close flyby of the gas giant. The spacecraft was at an altitude of 10,300 miles above Jupiter's cloud tops.

4. A New Test for Life on Other Planets 

A simple chemistry method could vastly enhance how scientists search for signs of life on other planets. The test uses a liquid-based technique known as capillary electrophoresis to separate a mixture of organic molecules into its components. It was designed specifically to analyze for amino acids, the structural building blocks of all life on Earth.

5. Blurring the Line Between Asteroid and Comet  

Our NEOWISE mission recently discovered some celestial objects traveling through our neighborhood, including one on the blurry line between asteroid and comet. An object called 2016 WF9 was detected by the NEOWISE project in November 2016 and it's in an orbit that takes it on a scenic tour of our solar system. A different object, discovered by NEOWISE a month earlier, is more clearly a comet, releasing dust as it nears the sun.

How do space plants grow? This experiment on the International Space Station hopes to find out. Space-grown plants look mostly normal, but have some distinct features compared to plants grown on Earth – most notably in the way their roots grow.

Roots evolved to grow “down” to search out nutrients and water, and on Earth, that response is predominantly governed by the force of gravity. But how does a plant know which way is down when there is no “down”? What determines the direction in which the plant’s roots should grow in space?

We are studying the molecular genetic signals that help guide plant growth in the novel environment of spaceflight, including how plants use new molecular “tools” to sense and respond to their environment when familiar signals are absent. What we learn could improve the way we grow plants in microgravity on future space missions, enabling crews to use plants for food and oxygen. This is just one of many petri plates filled with tiny plants from the Characterizing Arabidopsis Root Attractions-2 (CARA-2) that was recently harvest aboard the space station.
