Solar System: Things To Know  This Week

@saraxmix: What is it that makes you go back up there once you're home?

Becoming a Space Scientist

Astronauts train all over the world, including at Johnson Space Center. Here, they learn not just how to live aboard the International Space Station, but also how to conduct science in microgravity.

Astronauts serve as the eyes and hands of researchers while their experiments are in space, so they must be trained in everything from using a microscope, to maintaining the equipment for combustion experiments.

Check out this week’s episode of NASA Explorers as we go to class with an astronaut.

Twins Study Reddit AMA

Our Human Research Program is conducting a Twins Study on retired twin astronauts Scott and Mark Kelly. The study began during Scott Kelly’s One-Year Mission, which encompassed International Space Station Expeditions 43, 44, 45 and 46. 

Now that Scott has returned from space, researchers are integrating data as well as taking measurements on Earth from the twins. This is the first time we have conducted Omics research on identical twins. Omics is a broad area of biological and molecular studies that, in general, means the study of the entire complement of biomolecules, like proteins; metabolites or genes. 

Comparing various types of molecular information on identical individuals while one undergoes unique stresses, follows a defined diet, and resides in microgravity to one who resides on Earth, with gravity, should yield interesting results. It is hoped one day that all individuals will have access to having their Omics profiles done. This is a first step towards personalizing medicine for astronauts and hopefully for the rest of us. 

For background, check out NASA’s Omics video series at https://www.nasa.gov/twins-study.

During this Reddit AMA, you can ask our researchers anything about the Twins Study and Omics.

Participants include:

Kjell Lindgren, M.D., NASA astronaut, Expedition 44/45 Flight Engineer and medical officer

Susan M. Bailey, Ph.D., Twins Study Principal Investigator, Professor, Radiation Cancer Biology & Oncology, Department of Environmental and Radiological Health Sciences, College of Veterinary Medicine & Biomedical Sciences, Colorado State University

What Makes the Artemis Moon Mission NASA's Next Leap Forward?

When NASA astronauts return to the Moon through Artemis, they will benefit from decades of innovation, research, and technological advancements. We’ll establish long-term lunar science and exploration capabilities at the Moon and inspire a new generation of explorers—the Artemis Generation.

Meet the Space Launch System rocket, or SLS. This next-generation super heavy-lift rocket was designed to send astronauts and their cargo farther into deep space than any rocket we’ve ever built. During liftoff, SLS will produce 8.8 million pounds (4 million kg) of maximum thrust, 15 percent more than the Saturn V rocket.

SLS will launch the Orion spacecraft into deep space. Orion is the only spacecraft capable of human deep space flight and high-speed return to Earth from the vicinity of the Moon. More than just a crew module, Orion has a launch abort system to keep astronauts safe if an emergency happens during launch, and a European-built service module, which is the powerhouse that fuels and propels Orion and keeps astronauts alive with water, oxygen, power, and temperature control.

Orion and SLS will launch from NASA’s Kennedy Space Center in Florida with help from Exploration Ground Systems (EGS) teams. EGS operates the systems and facilities necessary to process and launch rockets and spacecraft during assembly, transport, launch, and recovery.

The knowledge we've gained while operating the International Space Station has opened new opportunities for long-term exploration of the Moon's surface. Gateway, a vital component of our Artemis plans, is a Moon-orbiting space station that will serve as a staging post for human expeditions to the lunar surface. Crewed and uncrewed landers that dock to Gateway will be able to transport crew, cargo, and scientific equipment to the surface.

Our astronauts will need a place to live and work on the lunar surface. Artemis Base Camp, our first-ever lunar science base, will include a habitat that can house multiple astronauts and a camper van-style vehicle to support long-distance missions across the Moon’s surface. Apollo astronauts could only stay on the lunar surface for a short while. But as the Artemis base camp evolves, the goal is to allow crew to stay at the lunar surface for up to two months at a time.

The Apollo Program gave humanity its first experience traveling to a foreign world. Now, America and the world are ready for the next era of space exploration. NASA plans to send the first woman and first person of color to the lunar surface and inspire the next generation of explorers.

Our next adventure starts when SLS and Orion roar off the launch pad with Artemis I. Together with commercial and international partners, NASA will establish a long-term presence on the Moon to prepare for missions to Mars. Everything we’ve learned, and everything we will discover, will prepare us to take the next giant leap: sending the first astronauts to Mars.

Two rings to shear them all!

This GIF shows a drop of insulin solution contained by surface tension in the Ring Sheared Drop device as part of an experiment conducted aboard the International Space Station. The device pins a drop of liquid between two rings and rotates one while keeping the other stationary to create shear flow, or a difference in velocity between adjacent liquid layers. Researchers used the device to study protein aggregates called amyloid fibrils, which may be related to diseases such as Alzheimer’s, Parkinson’s, and type 2 diabetes.

Scientists investigating the mechanisms of certain diseases on Earth must contend with the forces of gravity and the interaction between liquids and solid containers. These forces differ from such interfaces in the body, such as those in arteries and brain tissue, and can affect results. The Ring Sheared Drop investigation team developed a device that uses surface tension rather than a solid container to hold liquids, something possible only in microgravity!

Fluid extracted after each run will return to Earth aboard a Dragon capsule on September 30 so researchers can determine the extent of protein fibril formation, study their structure, and compare both to what happens in ground-based controls. Results could improve the fundamental understanding of how amyloid fibrils form and are transported, as well as the effects of shear at fluid interfaces relevant to conditions in the body.

A Year on the Sun Through Our Satellite’s Eyes

Did you know we’re watching the Sun 24/7 from space?

We use a whole fleet of satellites to monitor the Sun and its influences on the solar system. One of those is the Solar Dynamics Observatory. It’s been in space for eight years, keeping an eye on the Sun almost every moment of every day. Launched on Feb. 11, 2010, this satellite (also known as SDO) was originally designed for a two-year mission, but it’s still collecting data to this day — and one of our best ways to keep an eye on our star.

To celebrate another year of SDO, we’re sharing some of our favorite solar views that the spacecraft sent back to Earth in 2017.

 March: A long spotless stretch

For 15 days starting on March 7, SDO saw the yolk-like spotless Sun in visible light.

The Sun goes through a natural 11-year cycle of activity marked by two extremes: solar maximum and solar minimum. Sunspots are dark regions of complex magnetic activity on the Sun’s surface, and the number of sunspots at any given time is used as an index of solar activity.

Solar maximum = intense solar activity and more sunspots

Solar minimum = less solar activity and fewer sunspots

This March 2017 period was the longest stretch of spotlessness since the last solar minimum in April 2010 – a sure sign that the solar cycle is marching on toward the next minimum, which scientists expect in 2019-2020. For comparison, the images on the left are from Feb. 2014 – during the last solar maximum –  and show a much spottier Sun.

June: Energized active regions

 A pair of relatively small but frenetic active regions – areas of intense and complex magnetic fields – rotated into SDO’s view May 31 – June 2, while spouting off numerous small flares and sweeping loops of plasma. The dynamic regions were easily the most remarkable areas on the Sun during this 42-hour period.

July: Two weeks in the life of a sunspot

On July 5, SDO watched an active region rotate into view on the Sun. The satellite continued to track the region as it grew and eventually rotated across the Sun and out of view on July 17.  

With their complex magnetic fields, sunspots are often the source of interesting solar activity: During its 13-day trip across the face of the Sun, the active region — dubbed AR12665 — put on a show for our Sun-watching satellites, producing several solar flares, a coronal mass ejection and a solar energetic particle event. 

August: An eclipse in space

While millions of people in North America experienced a total solar eclipse on Aug. 21, SDO saw a partial eclipse from space. SDO actually sees several lunar transits a year from its perspective – but an eclipse on the ground doesn’t necessarily mean that SDO will see anything out of the ordinary. Even on Aug. 21, SDO saw only 14 percent of the Sun blocked by the Moon, while most US residents saw 60 percent blockage or more.

September: A spate of solar activity

In September 2017, SDO saw a spate of solar activity, with the Sun emitting 31 notable flares and releasing several powerful coronal mass ejections between Sept. 6-10. Solar flares are powerful bursts of radiation, while coronal mass ejections are massive clouds of solar material and magnetic fields that erupt from the Sun at incredible speeds.

One of the flares imaged by SDO on Sept. 6 was classified as X9.3 – clocking in at the most powerful flare of the current solar cycle. The current cycle began in December 2008 and is now decreasing in intensity, heading toward solar minimum. During solar minimum, such eruptions on the Sun are increasingly rare, but history has shown that they can nonetheless be intense.

September: A trio of tempests

Three distinct solar active regions with towering arches rotated into SDO’s view over a three-day period from Sept. 24-26. Charged particles spinning along the ever-changing magnetic field lines above the active regions trace out the magnetic field in extreme ultraviolet light, a type of light that is typically invisible to our eyes, but is colorized here in gold. To give some sense of scale, the largest arches are many times the size of Earth.

December: A curling prominence

SDO saw a small prominence arch up and send streams of solar material curling back into the Sun over a 30-hour period on Dec. 13-14. Prominences are relatively cool strands of solar material tethered above the Sun’s surface by magnetic fields.

 December: Solar question mark

An elongated coronal hole — the darker area near the center of the Sun’s disk — looked something like a question mark when seen in extreme ultraviolet light by SDO on Dec. 21-22. Coronal holes are magnetically open areas on the Sun that allow high-speed solar wind to gush out into space. They appear as dark areas when seen in certain wavelengths of extreme ultraviolet light.

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.
