Sarah Parcak Quotes

Satellites record data in different parts of the light spectrum that we can't see. And it's that information that allows satellites to be so powerful in terms of looking at things like vegetation health, finding different kinds of geology that may indicate an oil deposit or some kind of mineralogical deposit that can be mined.

Hubble orbits high, outside Earth's atmosphere so it can see a wide spectrum of light our atmosphere blocks.

For in 1900 all electromagnetic radiation of longer wavelengths was already known at least to the extent that one could not seek in it the more striking characteristics of X-rays such as, for example, the strong penetrating power.

Some things are only capable of being done in space. Examples of that are looking at our Earth from that far away, and understanding the entire processes of storms and weather patterns, and oceans, and coastlines.

Archaeologists use datasets from NASA and commercial satellites, processing the information using various off-the-shelf computer programs. These datasets allow us to see beyond the visible part of the light spectrum into the near, middle, and far infrared.

WorldView-3 goes into the mid-infrared wavelength, allowing you to see very subtle geological differences on the sites at a 0.4-metre resolution.

The scale of light can be described by numbers called the frequency and as the numbers get higher, the light goes from red to blue to ultraviolet. We can't see ultraviolet light, but it can affect photographic plates. It's still light only the number is different.

All of us know today the value of communications satellites, weather satellites, resources satellites, etc.

Scientists use satellites to track weather, map ice sheet melting, detect diseases, show ecosystem change... the list goes on and on. I think nearly every scientific field benefits or could benefit from satellite imagery analysis.

To understand how quickly we're cooking the planet, we need good data. To have good data, we need good satellites.

If you think about all the light that enters - that enters the lens of a camera, that's much more than a photo. The light field is all the higher-dimensional information that's lost in a regular photo. When we record all this information, that provides us the opportunity in software after the fact.

There are so many previously unknown sites and structures all over the world. And I think most importantly what satellites help to show us is we've actually only found a fraction of a percent of ancient settlements and sites all over the world.

For example, some stars put out large amounts of energy in the infrared part of the spectrum, so that this can produce a different relative magnitude rating than using light energy from the middle of the spectrum.

The plate at each point only sends back to the eye the simple colour imprinted. The other colours are destroyed by interference. The eye thus perceives at each point the constituent colour of the image.

What is sure is that the satellite view of our world and its evolution is now a common reality.

I leaned in science class that everything that generates light generates a little bit of heat, but not everything that generates head generates light. So it is with journalism.

I'm an Egyptologist. I'm a remote sensing specialist, and I'm a space archaeologist.

I already find pyramids from space. Is there anything cooler than that?

It's an important tool to focus where we're excavating. It gives us a much bigger perspective on archaeological sites. We have to think bigger, and that's what the satellites allow us to do.

Satellite imagery is the only way we can map the looting patterns effectively.

Satellite datasets like WorldView can see objects as small as 1.5 feet in diameter. In 2014, WorldView-3 will be able to see objects a small as a foot.

Imagery is powerful. Imagery is provocative - satellite imagery much more so because it is from space, and it allows us to get this perspective that we don't have to have otherwise.

Many people may not recognize that the development of space exploration technologies has already helped benefit Earth in many ways, especially when it comes to communications, Earth observation and even fostering economic growth. Space technologies are surprisingly critical in impacting government, industry and personal daily decision-making.

The early universe was a dusty place, and the UV radiation from the hot, young black holes and stars would get enshrouded by dust, re-radiated, and scattered into red wavelengths like infra-red, causing these objects to remain obscured.

We can read your heart rate from a webcam without you wearing anything - we can just use the reflection of your face, which shows blood flow.
