Space Station Research: Air and Space Science

Each month, we highlight a different research topic on the International Space Station. In June, our focus is Air and Space Science.

How is the space station being used to study space? Studies in fundamental physics address space, time, energy and the building blocks of matter. Recent astronomical observation and cosmological models strongly suggest that dark matter and dark energy, which are entities not directly observed and completely understood, dominate these interactions at the largest scales.

The space station provides a modern and well-equipped orbiting laboratory for a set of fundamental physics experiments with regimes and precision not achievable on the ground. 

For example, the CALorimetric Electron Telescope (CALET) is an astrophysics mission that searches for signatures of dark matter (pictured above). It can observe discrete sources of high energy particle acceleration in our local region of the galaxy. 

How is the space station contributing to aeronautics? It provides a long-duration spaceflight environment for conducting microgravity physical science research. This environment greatly reduces buoyancy-driven convection and sedimentation in fluids. By eliminating gravity, space station allows scientists to advance our knowledge in fluid physics and materials science that could lead to better designated air and space engines; stronger, lighter alloys; and combustion processes that can lead to more energy-efficient systems.

How is the space station used to study air? The Cloud-Aerosol Transport System (CATS) is a laster remote-sensing instrument, or lidar, that measures clouds and tiny aerosol particles in the atmosphere such as pollution, mineral dust and smoke. These atmospheric components play a critical part in understanding how human activities such as fossil fuel burning contribute to climate change.

The ISS-RapidScat is an instrument that monitors winds for climate research, weather predictions and hurricane monitoring from the International Space Station.

NASA Technology in Your Life

How does NASA technology benefit life on Earth? It probably has an impact in more ways than you think! Since 1976, our Spinoff program has profiled nearly 2,000 space technologies that have transformed into commercial products and services. In celebration of Spinoff’s 40th year of publication, we’ve assembled a collection of spinoffs that have had the greatest impact on Earth. 

Take a look and see how many you utilize on a regular basis:

Digital Image Sensors

Whether you take pictures and videos with a DSLR camera or a cell phone, or even capture action on the go with a device like a GoPro Hero, you’re using NASA technology. The CMOS active pixel sensor in most digital image- capturing devices was invented when we needed to miniaturize cameras for interplanetary missions. This technology is also widely used in medical imaging and dental X-ray devices.

Enriched Baby Formula

While developing life support for Mars missions, NASA-funded researchers discovered a natural source for an omega-3 fatty acid previously found primarily in breast milk that plays a key role in infant development. The ingredient has since been added to more than 90% of infant formula on the market and is helping babies worldwide develop healthy brains, eyes and hearts.

NASTRAN Software

NASTRAN is a software developed by our engineers that performs structural analysis in the 1960s. Still popular today, it’s been used to help design everything from airplanes and cars to nuclear reactors and even Disney’s Space Mountain roller coaster.

Food Safety Standards

Looking to ensure the absolute safety of prepackaged foods for spaceflight, we partnered with the Pillsbury Company to create a new, systematic approach to quality control. Now known as Hazard Analysis and Critical Control Points (HACCP), the method has become an industry standard that benefits consumers worldwide by keeping food free from a wide range of potential chemical, physical and biological hazards.

Neutral Body Posture Specifications

What form does the human body naturally assume when all physical influences, including the pull of gravity, stop affecting it? We conducted research to find out using Skylab, America’s first space station, and later published specifications for what it called neutral body posture. The study has informed seat designs in everything from airplanes and office chairs to several models of Nissan automobiles.

Advanced Water Filtration

We recently discovered unexpected sources of water on the moon and Mars, but even so, space remains a desert for human explorers, and every drop must be recycled and reused. A nano filter devised to purify water in orbit is currently at work on Earth, in devices that supply water to remote villages as well as in a water bottle that lets hikers and adventurers stay hydrated using streams and lakes.

Swimsuit Designs

Wind-tunnel testing at our Langley Research Center played a key role in the development of Speedo’s LZR Racer swimsuit, proving which materials and seams best reduced drag as a swimmer cuts through the water. The swimsuit made a splash during its Olympic debut in 2008, as nearly every medal winner and world-record breaker wore the suit.

Air Purifier

When plants grow, they release a gas called ethylene that accelerates decay, hastening the wilting of flowers and the ripening of fruits and vegetables. Air circulation on Earth keeps the fumes from building up, but in the hermetically sealed environment of a spacecraft, ethylene poses a real challenge to the would-be space farmers. We funded the development of an ethylene scrubber for the International Space Station that has subsequently proved capable of purifying air on Earth from all kinds of pathogens and particulates. Grocery stores use it to keep produce fresh longer. It’s also been marketed for home use and has even been embraced by winemakers, who employ the scrubber to keep aging wine in barrels free from mold, mildew and musty odors.

Scratch-Resistant, UV-Reflective Lenses

Some of the earliest research into effective scratch-resistant coatings for prescription and sunglass lenses drew from work done at Ames Research Center on coatings for astronaut helmet visors and plastic membranes used in water purification systems. In the 1980s, we developed sunlight-filtering lenses to provide eye protection and enhance colors, and these lenses have found their way into sunglasses, ski goggles and safety masks for welders.

Dustbuster

An Apollo-era partnership with Black & Decker to build battery-operated tools for moon exploration and sample collection led to the development of a line of consumer, medical and industrial hand-held cordless tools. This includes the popular Dustbuster cordless vacuum.

Meet the all-female team of coders that brought us Apollo 11.

In 1969, the world watched as Neil Armstrong marked his historic achievement with the words, “That’s one small step for man, one giant leap for mankind.” His now-famous transmission was heard around the globe thanks to NASA’s Deep Space Network, which made communication from outer space possible.

That network was built by a woman named Susan Finley. She was part of an all-female team of coders whose work was integral to the success of the Apollo 11 mission. Science writer Nathalia Holt brings us their stories in her book, Rise of the Rocket Girls: The Women Who Propelled Us from Missiles to the Moon to Mars.

NASA Wants Deep Space Habitat Ideas

How will humans live on Mars? Well, NASA’s not really sure yet, but if you’ve got any ideas you can submit them now. The agency has just put out a call for proposals for “deep space habitation prototypes.”

from NASA’s press release:

NASA is soliciting proposals for the development of prototypes for deep space habitats that will give astronauts a place to call home during long-duration missions supporting the agency’s Journey to Mars.

Thanks to Trump, Scientists Are Planning to Run For Office

And they’ve got help.

For American science, the next four years look to be challenging. The newly inaugurated President Trump, and many of his Cabinet picks, have repeatedly cast doubt upon the reality of human-made climate change, questioned the repeatedly proven safety of vaccines. Since the inauguration, the administration has already frozen grants and contracts by the Environmental Protection Agency and gagged researchers at the US Department of Agriculture. Many scientists are asking themselves: What can I do?

And the answer from a newly formed group called 314 Action is: Get elected.

The organization, named after the first three digits of pi, is a political action committee that was created to support scientists in running for office. It’s the science version of Emily’s List, which focuses on pro-choice female candidates, or VoteVets, which backs war veterans. “A lot of scientists traditionally feel that science is above politics but we’re seeing that politics is not above getting involved in science,” says founder Shaughnessy Naughton. 

“We’re losing, and the only way to stop that is to get more people with scientific backgrounds at the table.”
