5 Ways The Moon Landing Changed Life On Earth

5 Ways the Moon Landing Changed Life on Earth

When Neil Armstrong took his first steps on the Moon 50 years ago, he famously said “that’s one small step for a man, one giant leap for mankind.” He was referring to the historic milestone of exploring beyond our own planet — but there’s also another way to think about that giant leap: the massive effort to develop technologies to safely reach, walk on the Moon and return home led to countless innovations that have improved life on Earth.

Armstrong took one small step on the lunar surface, but the Moon landing led to a giant leap forward in innovations for humanity.

Here are five examples of technology developed for the Apollo program that we’re still using today:

1. Food Safety Standards

As soon as we started planning to send astronauts into space, we faced the problem of what to feed them — and how to ensure the food was safe to eat. Can you imagine getting food poisoning on a spacecraft, hundreds of thousands of miles from home?

We teamed up with a familiar name in food production: the Pillsbury Company. The company soon realized that existing quality control methods were lacking. There was no way to be certain, without extensive testing that destroyed the sample, that the food was free of bacteria and toxins.

Pillsbury revamped its entire food-safety process, creating what became the Hazard Analysis and Critical Control Point system. Its aim was to prevent food safety problems from occurring, rather than catch them after the fact. They managed this by analyzing and controlling every link in the chain, from the raw materials to the processing equipment to the people handling the food.

Today, this is one of the space program’s most far-reaching spinoffs. Beyond keeping the astronaut food supply safe, the Hazard Analysis and Critical Point system has also been adopted around the world — and likely reduced the risk of bacteria and toxins in your local grocery store.

2. Digital Controls for Air and Spacecraft

The Apollo spacecraft was revolutionary for many reasons. Did you know it was the first vehicle to be controlled by a digital computer? Instead of pushrods and cables that pilots manually adjusted to manipulate the spacecraft, Apollo’s computer sent signals to actuators at the flick of a switch.

Besides being physically lighter and less cumbersome, the switch to a digital control system enabled storing large quantities of data and programming maneuvers with complex software.

Before Apollo, there were no digital computers to control airplanes either. Working together with the Navy and Draper Laboratory, we adapted the Apollo digital flight computer to work on airplanes. Today, whatever airline you might be flying, the pilot is controlling it digitally, based on the technology first developed for the flight to the Moon.

3. Earthquake-ready Shock Absorbers

A shock absorber descended from Apollo-era dampers and computers saves lives by stabilizing buildings during earthquakes.

Apollo’s Saturn V rockets had to stay connected to the fueling tubes on the launchpad up to the very last second. That presented a challenge: how to safely move those tubes out of the way once liftoff began. Given how fast they were moving, how could we ensure they wouldn’t bounce back and smash into the vehicle?

We contracted with Taylor Devices, Inc. to develop dampers to cushion the shock, forcing the company to push conventional shock isolation technology to the limit.

Shortly after, we went back to the company for a hydraulics-based high-speed computer. For that challenge, the company came up with fluidic dampers—filled with compressible fluid—that worked even better. We later applied the same technology on the Space Shuttle’s launchpad.

The company has since adapted these fluidic dampers for buildings and bridges to help them survive earthquakes. Today, they are successfully protecting structures in some of the most quake-prone areas of the world, including Tokyo, San Francisco and Taiwan.

4. Insulation for Space

We’ve all seen runners draped in silvery “space blankets” at the end of marathons, but did you know the material, called radiant barrier insulation, was actually created for space?

Temperatures outside of Earth’s atmosphere can fluctuate widely, from hundreds of degrees below to hundreds above zero. To better protect our astronauts, during the Apollo program we invented a new kind of effective, lightweight insulation.

We developed a method of coating mylar with a thin layer of vaporized metal particles. The resulting material had the look and weight of thin cellophane packaging, but was extremely reflective—and pound-for-pound, better than anything else available.

Today the material is still used to protect astronauts, as well as sensitive electronics, in nearly all of our missions. But it has also found countless uses on the ground, from space blankets for athletes to energy-saving insulation for buildings. It also protects essential components of MRI machines used in medicine and much, much more.

5. Healthcare Monitors

Patients in hospitals are hooked up to sensors that send important health data to the nurse’s station and beyond — which means when an alarm goes off, the right people come running to help.

This technology saves lives every day. But before it reached the ICU, it was invented for something even more extraordinary: sending health data from space down to Earth.

When the Apollo astronauts flew to the Moon, they were hooked up to a system of sensors that sent real-time information on their blood pressure, body temperature, heart rate and more to a team on the ground.

The system was developed for us by Spacelabs Healthcare, which quickly adapted it for hospital monitoring. The company now has telemetric monitoring equipment in nearly every hospital around the world, and it is expanding further, so at-risk patients and their doctors can keep track of their health even outside the hospital.

Only a few people have ever walked on the Moon, but the benefits of the Apollo program for the rest of us continue to ripple widely.

In the years since, we have continued to create innovations that have saved lives, helped the environment, and advanced all kinds of technology.

Now we’re going forward to the Moon with the Artemis program and on to Mars — and building ever more cutting-edge technologies to get us there. As with the many spinoffs from the Apollo era, these innovations will transform our lives for generations to come.

Under Pressure

Structural Tests Underway for Top of World's Most Powerful Rocket

Testing is underway at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on the agency’s new Space Launch System, the world’s most powerful rocket. SLS and NASA’s Orion spacecraft will enable deep-space missions, beginning a new era of exploration beyond Earth’s orbit.

Engineers at Marshall have stacked four qualification articles of the upper part of SLS into a 65-foot-tall test stand using more than 3,000 bolts to hold the hardware together. Tests are currently underway to ensure the rocket hardware can withstand the pressures of launch and flight.

The integrated tests consists of:

1. Launch Vehicle Adapter

2. Frangible Joint Assembly

3. Interim Cryogenic Propulsion Stage

4. Orion Stage Adapter

Engineers are using 28 load pistons to push, pull and twist the rocket hardware, subjecting it to loads up to 40 percent greater than that expected during flight. More than 100 miles of cables are transmitting measurements across 1,900 data channels.

The Launch Vehicle Stage Adapter, LVSA, connects the SLS core stage and the Interim Cryogenic Propulsion Stage, ICPS. The LVSA test hardware is 26.5 feet tall, with a bottom diameter of 27.5 feet and a top diameter of 16.8 feet. The frangible joint, located between the LVSA and ICPS, is used to separate the two pieces of hardware during flight, allowing the ICPS to provide the thrust to send Orion onto its mission.

The ICPS is a liquid oxygen/liquid hydrogen-based system that will give Orion the big, in-space push needed to fly beyond the moon before it returns to Earth on the first flight of SLS in 2018. For this test series, the fuel tanks are filled with nonflammable liquid nitrogen and pressurized with gaseous nitrogen to simulate flight conditions. The nitrogen is chilled to the same temperature as the oxygen and hydrogen under launch conditions.

The Orion Stage Adapter connects the Orion spacecraft to the ICPS. It is 4.8 feet tall, with a 16.8-foot bottom diameter and 18-foot top diameter.

The first integrated flight for SLS and Orion will allow NASA to use the lunar vicinity as a proving ground to test systems farther from Earth, and demonstrate Orion can get to a stable orbit in the area of space near the moon in order to support sending humans to deep space, including the Journey to Mars.

It’s a Bird! It’s a Plane! It’s NASA’s Five Newest Airborne Campaigns!

We’re not just doing research in space! From the land, the sea and the sky, we study our planet up close. Right now, we’re gearing up for our newest round of Earth Expeditions, using planes, boats and instruments on the ground to study Earth and how it’s changing.

The newest round of campaigns takes place all across the United States – from Virginia to Louisiana to Kansas to California.

The five newest missions will combine measurements from the ground, the sea, air and space to investigate storms, sea level rise and processes in the atmosphere and ocean.

Let’s meet the newest Earth science missions:

1. IMPACTS

The Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms will start from Wallops Flight Facility in Virginia to understand how bands of snow form during winter storms in the East Coast. This research will help us better forecast intense snowfall during extreme winter weather.

2. ACTIVATE

Flying out of Langley Research Center, the Aerosol Cloud Meteorology Interactions over the Western Atlantic Experiment is studying how specific types of clouds over oceans affect Earth’s energy balance and water cycle. The energy balance is the exchange of heat and light from the Sun entering Earth’s atmosphere vs. what escapes back into space.

3. Delta-X

Farther south, Delta-X is flying three planes around the Mississippi River Delta to study how land is deposited and maintained by natural processes. Studying these processes can help us understand what will happen as sea levels continue to rise.

4. DCOTSS

Heading out to the Midwest this summer, the Dynamics and Chemistry of the Summer Stratosphere mission will study how thunderstorms can carry pollutants from high in the atmosphere deep into the lower stratosphere, where they can affect ozone levels.

5. S-MODE

About 200 miles off the coast of San Francisco, the Sub-Mesoscale Ocean Dynamics Experiment is using ships, planes and gliders to study the impact that ocean eddies have on how heat moves between the ocean and the atmosphere.

It’s A Bird! It’s A Plane! It’s NASA’s Five Newest Airborne Campaigns!

These missions are kicking off in January, so stay tuned for our updates from the field! You can follow along with NASA Expeditions on Twitter and Facebook.

A persistent heatwave has been lingering over parts of Europe, setting record high temperatures and turning typically green landscapes brown.

The United Kingdom experienced its driest first half of summer (June 1 to July 16) on record.

These images, acquired by our Terra satellite, show the burned landscape of the United Kingdom and northwestern Europe as of July 15, 2018, compared with July 17, 2017.

Peter Gibson, a postdoctoral researcher at our Jet Propulsion Laboratory, examined how rising global temperatures are linked to regional heatwaves. “If the globe continues to warm, it’s clear we will continue to see events like this increasing in frequency, severity and duration,” Gibson said. “We found that parts of Europe and North America could experience an extra 10 to 15 heatwave days per degree of global warming beyond what we have seen already.”

This composite image shows a coronal mass ejection, a type of space weather linked to solar energetic particles, as seen from two space-based solar observatories and one ground-based instrument. The image in gold is from NASA’s Solar Dynamics Observatory, the image in blue is from the Manua Loa Solar Observatory’s K-Cor coronagraph, and the image in red is from ESA and NASA’s Solar and Heliospheric Observatory.

Our constantly-changing sun sometimes erupts with bursts of light, solar material, or ultra-fast energized particles — collectively, these events contribute to space weather. A new study shows that the warning signs of one type of space weather event can be detected tens of minutes earlier than with current forecasting techniques – critical extra time that could help protect astronauts in space.

Chandra X-Ray Observatory, We Appreciate You

On July 23, 1999, the Space Shuttle Columbia blasted off from the Kennedy Space Center carrying the Chandra X-ray Observatory. In the two decades that have passed, Chandra’s powerful and unique X-ray eyes have contributed to a revolution in our understanding of the cosmos.

Since its launch 20 years ago, Chandra's unrivaled X-ray vision has changed the way we see the universe.

Chandra X-Ray Observatory, We Appreciate You

Chandra has captured galaxy clusters – the largest gravitationally bound objects in the universe – in the process of merging.

Chandra has shown us the powerful wind and shock fronts that rumble through star-forming systems.

And a star school, so to speak -- home to thousands of the Milky Way's biggest and brightest.

Carl Sagan said, "We are made of star-stuff." It's true. Most of the elements necessary for life are forged inside stars and blasted into interstellar space by supernovas. Chandra has tracked them.

Thank you Chandra X-Ray! To more adventures with you!

Check out Chandra’s 20th anniversary page to see how they are celebrating.

See Why Our Researchers Explore Earth's Extreme and Remote Environments

When we talk about exploration in far-flung places, you might think of space telescopes taking images of planets outside our solar system, or astronauts floating on the International Space Station.

But did you know our researchers travel to some of Earth's most inaccessible and dangerous places, too?

Two scientists working with the ICESat-2 mission just finished a trek from the South Pole to latitude 88 south, a journey of about 450 miles. They had to travel during the Antarctic summer - the region's warmest time, with near-constant sunshine - but the trek was still over solid ice and snow.

The trip lasted 14 days, and was an important part of a process known as calibration and validation. ICESat-2 will launch this fall, and the team was taking extremely precise elevation measurements that will be used to validate those taken by the satellite.

Sometimes our research in Earth's remote regions helps us understand even farther-flung locations…like other planets.

Geologic features on Mars look very similar to islands and landforms created by volcanoes here on our home planet.

As hot jets of magma make their way to Earth's surface, they create new rocks and land - a process that may have taken place on Mars and the Moon.

In 2015, our researchers walked on newly cooled lava on the Holuhraun volcano in Iceland to take measurements of the landscape, in order to understand similar processes on other rocky bodies in our solar system.

There may not be flowing lava in the mangrove forests in Gabon, but our researchers have to brave mosquitoes and tree roots that reach up to 15-foot high as they study carbon storage in the vegetation there.

The scientists take some measurements from airplanes, but they also have to gather data from the ground in one our of planet's most pristine rainforests, climbing over and around roots that can grow taller than people. They use these measurements to create a 3-D map of the ecosystem, which helps them understand how much carbon in stored in the plants.

You can follow our treks to Earth’s most extreme locales on our Earth Expeditions blog.

Hello. As the moon is moving farther from the earth, we will some day have no more solar eclipses. When will this happen?

Yup someday (I believe in about 650 million years) the moon will be too far away for solar eclipses to occur. We’re actually quite lucky that we get to see them at all. Not all planets get to experience eclipses.
