A Tour of our Moon

Want to go to the Moon? 

Let our Lunar Reconnaissance Orbiter take you there!

Our lunar orbiter, also known as LRO, has been collecting data on lunar topography, temperature, resources, solar radiation, and geology since it launched nine years ago. Our latest collection of this data is now in 4K resolution. This updated "Tour of the Moon" takes you on a virtual tour of our nearest neighbor in space, with new science updates from the vastly expanded data trove.

Orientale Basin

First stop, Orientale Basin located on the rim of the western nearside. It's about the size of Texas and is the best-preserved impact structure on the Moon. Topography data from LRO combined with gravity measurements from our twin GRAIL spacecraft reveal the structure below the surface and help us understand the geologic consequences of large impacts.

South-Pole and Shackleton Crater

Unlike Earth, the Moon's axis is barely tilted relative to the Sun. This means that there are craters at the poles where the sunlight never reaches, called permanently shadowed regions. As a result, the Moon's South Pole has some of the coldest measured places in the solar system. How cold? -410 degrees F.

Because these craters are so cold and dark, water that happens to find its way into them never has the opportunity to evaporate. Several of the instruments on LRO have found evidence of water ice, which you can see in the highlighted spots in this visualization.

South-Pole Aitken Basin

South Pole-Aitken Basin is the Moon's largest, deepest and oldest observed impact structure. Its diameter is about 2,200 km or 1,367 miles across and takes up 1/4 of the Moon! If there was a flat, straight road and you were driving 60 mph, it would take you about 22 hours to drive across. And the basin is so deep that nearly two Mount Everests stacked on each other would fit from the bottom of the basin to the rim. South-Pole Aitken Basin is a top choice for a landing site on the far side of the Moon.

Tycho Crater

Now let's go to the near side. Tycho Crater is 100 million years young. Yes, that's young in geologic time. The central peak of the impact crater likely formed from material that rebounded back up after being compressed in the impact, almost like a spring. Check out that boulder on top. It looks small in this image, but it could fill a baseball stadium.

Aristarchus Plateau

Also prominent on the nearside is the Aristarchus Plateau. It features a crater so bright that you could see it with your naked eye from Earth! The Aristarchus Plateau is particularly interesting to our scientists because it reveals much of the Moon's volcanic history. The region is covered in rocks from volcanic eruptions and the large river-like structure is actually a channel made from a long-ago lava flow.

Apollo 17 Landing Site

As much as we study the Moon looking for sites to visit, we also look back at places we've already been. This is because the new data that LRO is gathering helps us reinterpret the geology of familiar places, giving scientists a better understanding of the sequence of events in early lunar history.

Here, we descend to the Apollo 17 landing site in the Taurus-Littrow valley, which is deeper than the Grand Canyon. The LRO camera is even able to capture a view of the bottom half of the Apollo 17 Lunar Lander, which still sits on the surface, as well as the rover vehicle. These images help preserve our accomplishment of human exploration on the Moon's surface.

North Pole

Finally, we reach the North Pole. Like the South Pole, there are areas that are in permanent shadow and others that bask in nearly perpetual light. LRO scientists have taken detailed brightness and terrain measurements of the North Pole in order to model these areas of sunlight and shadow through time.  Sunlit peaks and crater rims here may be ideal locations for generating solar power for future expeditions to the Moon.

LRO was designed as a one-year mission. Now in its ninth year, the spacecraft and the data emphasize the power of long-term data collection. Thanks to its many orbits around the Moon, we have been able to expand on lunar science from the Apollo missions while paving the way for future lunar exploration. And as the mission continues to gather data, it will provide us with many more opportunities to take a tour of our Moon.

6 Ways You Are Safer Thanks to NASA Technology

By now everyone knows that we are to thank for the memory foam in your mattress and the camera in your cell phone. (Right? Right.)

But our technology is often also involved behind the scenes—in ways that make the products we use daily safer and stronger, and in some cases, that can even save lives.

Here are some examples from this year’s edition of Spinoff, our yearly roundup of “space in your life”:

Impact Testing

What happens to your car bumper in an accident? When does it crumple and when does it crack? And are all bumpers coming off the assembly line created equal?

These types of questions are incredibly important when designing a safe car, and one technology that helps almost every U.S. automobile manufacturer find answers is something we helped develop when we had similar questions about the Space Shuttle.

Before flying again after the Columbia disaster in 2003, we had to be sure we understood what went wrong and how to prevent it from ever happening again. We worked with Trilion, Inc. to develop a system using high-speed cameras and software to analyze every impact—from the one that actually happened on the Shuttle to any others we could imagine—and design fixes.

Finding Survivors

We’re pretty good at finding things you can’t see with the naked eye—from distant exoplanets to water on Mars.

But there are also plenty of uses for that know-how on Earth.

One example that has already saved lives: locating heartbeats under debris.

Engineers at our Jet Propulsion Laboratory adapted technology first devised to look for gravity fluctuations to create FINDER, which stands for Finding Individuals for Disaster and Emergency Response and can detect survivors through dense rubble.

We have licensed the technology to two companies, including R4, and it has already been used in natural disaster responses, including after earthquakes in Nepal, Mexico City, Ecuador, and after Hurricane Maria in Puerto Rico.

Fighting Forest Fires

As we have seen this year with devastating wildfires in California, forest fires can spread incredibly quickly.

Knowing when to order an evacuation, where to send firefighters, and how to make every other decision—all amid a raging inferno—depends on having the most up-to-date information as quickly as possible.

Using our expertise in remote sensing and communicating from space, we helped the U.S. Forest Service make its process faster and more reliable, so the data from airborne sensors gets to decision makers on the front line and at the command center in the blink of an eye.

Safer, Germ-Free Ambulances 

When paramedics come racing into a home, the last thing anybody is worrying about is where the ambulance was earlier that morning. A device we helped create ensures you won’t have to.

AMBUstat creates a fog that sterilizes every surface in an ambulance in minutes, so any bacteria, viruses or other contaminants won’t linger on to infect the next patient.

This technology works its magic through the power of atomic oxygen—the unpaired oxygen atoms that are common in the upper reaches of Earth’s atmosphere. We’ve had to learn about these atoms to devise ways to ensure they won’t destroy our spacecraft or harm astronauts, but here, we were able to use that knowledge to direct that destructive power at germs.

Air Filters 

Did you know the air we breathe inside buildings is often up to 10 times more polluted than the air outdoors?

Put the air under a microscope and it’s not pretty, but a discovery we made in the 1990s can make a big impact.

We were working on a way to clear a harmful chemical that accumulates around plants growing on a spacecraft, and it turned out to also neutralize bacteria, viruses, and mold and eliminate volatile organic compounds.

Now air purifiers using this technology are deployed in hospital operating rooms, restaurant kitchens, and even major baseball stadiums to improve air quality and keep everyone healthier. Oh, and you can buy one for your house, too.

Driverless Cars 

Car companies are moving full-speed ahead to build the driverless cars of the not-so-distant future. Software first created to help self-learning robots navigate on Mars may help keep passengers and pedestrians safer once those cars hit the road. The software creates an artificially intelligent “brain” for a car (or drone, for that matter) that can automatically identify and differentiate between cars, trucks, pedestrians, cyclists, and more, helping ensure the car doesn’t endanger any of them. 

So, now that you know a few of the spinoff technologies that we helped develop, you can look for them throughout your day. Visit our page to learn about more spinoff technologies: https://spinoff.nasa.gov Make sure to follow us on Tumblr for your regular dose of space: http://nasa.tumblr.com.
