Hard-to-reach places, like the Amazon rainforest, can hide traces of past civilizations. But scientists are finding ways to explore these areas from above and discover the effects these ancient peoples had on their environment.

It's late, pitch dark and a self-driving car winds down a narrow country road. Suddenly, three hazards appear at the same time. With no human at the wheel, the car uses smart eyes, sensors that'll resolve these details all in a...

We have archives of films, newspapers, even seeds -- what if we could make one for the entire surface of the earth? Drawing on his experience mapping an ancient city in the Honduran jungle, archaeologist Chris Fisher makes the case for...

When you think about archaeology, space technology probably isn’t the first thing that comes to mind. But from satellites to cosmic rays, archaeologists actually look to space a lot more than you might think!

If we don't act now on climate change, this coming century may be one of humanity's last, says António Guterres, Secretary-General of the United Nations. As the world recovers from the COVID-19 pandemic, Guterres urges us to use this...

The Channeled Scablands of the Pacific Northwest hide an astonishing secret. Evidence of a massive flood that shaped the entire region lies just beneath its landscape. But it can only be seen with cutting edge LIDAR technology. Join Joe...

What is geomatics? Why it's the branch of science that deals with the collection, analysis, and interpretation of data relating to the earth's surface. How is it done? Well we've got Nigel here to tell us all about it! You may know about...

Before archeologists can excavate a site, they need to know where to dig. Surveys are the techniques used to find these places. What are the techniques used in archeological survey, as well as the technologies? What is LiDAR and how is...

Dive into the high-tech world of modern archaeology as we explore how cutting-edge tools like advanced scanners and LIDAR technology unravel the mysteries of our ancestors. From reconstructing the brain of Cro-Magnon man to unveiling...

How does a radiometer work when studying weather cloud structures? How are natural and manmade aerosols created and how do they affect the environment?<br/>
Mysterious Weather Clouds, Part 2

A Google self-driving car finally was the cause of a crash on Valentine's Day after driving more than 1.3 million miles since 2009, reported Wired. No one was hurt and the damage was minimal, but the crash shows that companies developing...

From the section: Introduction to Self-Driving Cars. In this section, we’ll cover a brief history and an overall outcome that you can expect by the end of this course.



Introduction to Self-Driving Cars: A Brief History of...

The circular villages all had remarkably similar layouts, with elongated mounds circling a central plaza like marks on a clock. <br/>

NASA Goddard is preparing to demonstrate for the fist time in space, a 3-wavelength, laser remote sensing instrument. The Cloud-Aerosol Transport System or CATS will measure clouds and aerosols in the Earth's atmosphere. This...

Researchers used laser technology to scan a hill next to an ancient Mayan city and were shocked to find the hill was actually ruins of structures from a different civilization.

The OSIRIS-REx Laser Altimeter (OLA) will provide a three-dimensional map of asteroid Bennu’s shape, which will allow scientists to understand the context of the asteroid’s geography and the sample location. OLA is...

ICESat-2's instrument, ATLAS, is designed to measure heights on Earth. ATLAS has three main tasks: transmitting a pattern of six laser beams, collecting the laser photons that return to the satellite after reflecting off Earth, and...

Remote, recently formed (via volcanic eruptions) oceanic islands in the deep ocean can be studied by satellite lidar altimetry as ICESat2 has been doing, but especially with the satellite lidar...

NASA and the U.S. Forest Service are surveying the forests of Interior Alaska. The airborne study using an advanced instrument will create a 3D map of the forest composition. This will enable scientists to see patterns of fire...

NASA's Cloud Physics Lidar (CPL) instrument, flying aboard an unmanned Global Hawk aircraft in this summer's Hurricane and Severe Storm Sentinel or HS3 mission, is studying the changing profile of the atmosphere in detail to learn...

On September 20, 2017, Hurricane Maria barreled across Puerto Rico with winds of up to 155 miles per hour and battering rain that flooded towns, knocked out communications networks and destroyed the power grid. In the rugged central...

On January 22, 2015, the Cloud-Aerosol Transport System (CATS) was installed on the International Space Station. The team monitored the progress of the installation from NASA's Goddard Space Flight Center, where CATS was designed and...

Want to know the 3D shape of terrain on another planet? Want to study the height and density of Earth's forests? An amazing tool called LIDAR can help! Learn more in this video.
