A picture is worth 1,000 words.
It’s getting busy up there – since 1957 we’ve launched thousands of satellites into orbit (3,000 – 6,000). Governments and private companies are currently operating about 1,000 active satellites for telecommunications, intelligence-gathering and scientific research. This includes the big weather satellites parked about 22,000 miles away.

And there are also dozens of other imaging satellites in much lower orbits flying just a few hundred miles overhead. The remote sensing instruments they carry capture digital pictures of the planet at various levels of detail, and at various wavelengths – including visible light, the colors that we can see, and parts of the spectrum that would otherwise be invisible to us, like infrared and microwave energy.

We know where to go to help us answer that question
We know where to go to help us answer that question. Beginning this summer, SkyTruth and LightHawk joined forces to investigate Marcellus drilling. Armed with SkyTruth maps and a detailed flight plan, we flew to verify drilling activity at locations where permits had recently been issued by the state.

Who is SkyTruth? WV-based 501(c)(3) established 2001
Satellite images + remote sensing to investigate, illustrate enviro issues Oil and gas drilling, fracking Pollution events (BP spill) Mining (hardrock, coal, tar sands) Climate change impacts Remote monitoring and surveillance

Deepwater Horizon rig sinking, April 22, 2010
Independent Monitoring: BP spill proved the value of credible, independent oil pollution assessment and monitoring. For weeks, BP and federal government provided unrealistically low estimate of size of spill. Satellite image analysis by SkyTruth revealed, within first week, that spill was at least 25 times larger than official estimate. Ultimately scientists determined spill was 60 times larger than BP’s estimate of 1000 barrels per day. Deepwater Horizon rig sinking, April 22, 2010

Detail from NASA/MODIS satellite image, April 29, 2010
Within a week, by measuring the size of the oil slick on the images, we calculated the spill rate was at least 20,000 barrels per day. This was 20 times larger than official BP and Coast Guard estimates at the time. Months later, government scientists determined the spill rate from the failed well was about 60,000 barrels per day. This image, taken by NASA’s Terra satellite on April 29, 2010, shows the oil slick making first landfall in the marshes of Louisiana. Detail from NASA/MODIS satellite image, April 29, 2010

That got us a lot of attention
That got us a lot of attention. We did interviews for CNBC, MSNBC, Fox News and Al Jazeera. Our work was covered by NPR, the Washington Post, and the New York Times. I had giant black gas-guzzling SUV’s whisking me from Shepherdstown to DC and back, and makeup artists painting eyebrows on my face. A very bizarre experience.

Who’s analysis is correct?
Closer to home, we’re also partnering with Shepherd University faculty, staff and students, looking at inexpensive ways to acquire up-to-the-minute, high-resolution imagery to monitor impacts associated with natural gas drilling.
