They found thin layers of iridium in rocks that dated to 65 million years ago
and since iridium is naturally very rare On earth they proposed that it s source was a meteorite that impacted the Earth at this time.
but other researchers began to find similar iridium layers in rocks from other locations On earth suggesting a global event
Using data available from the Earth-observing Landsat satellite the team looked at all the Western fires that burned more than 1000 acres (400 hectares) of both public and private land starting in 1984.
Cretaceous period climate All over North america the highest Cretaceous fossils are found directly beneath a thin layer of sediments that contain an unusual amount of iridium an element otherwise uncommon in Earth s crust.
The first was data from the Landsat 7 satellite which launched in 1999 and has been snapping satellite photos of the globe ever since.
Next Landsat's operator the U s. Geological Survey altered its policies to make all of the data from Landsat 7 and previous Landsat satellites free.
Because groundwater is the single biggest thing that moves around on the Earth's surface new satellite systems can detect changes in Earth's gravity due to groundwater depletion.

From satellite observations such as Landsat images and radar interferometry Mouginot and his co-authors tracked the speed of West Antarctica's six largest glaciers.
NASA's Landsat satellites which have been snapping pictures of the Earth's surface for more than 40 years now have instruments that can produce images with 49-to 98-foot (15 to 30 m) resolutions.
But forests in Landsat images look like green paint strokes. G-Liht can produce photographs at a smaller and sharper resolution:
For CO2 emissions to be monitored accurately from space it would take a coordinated network of satellites similar to existing weather satellites he said.
Other options putting OCO-type instruments on weather satellites or on the International Space station (ISS) would also take a long time,

Satellites smash debris threatens Hubble An active communications satellite owned by Iridium Satellite of Bethesda, Maryland, slammed into a defunct Russian military communications satellite 800 kilometres above Siberia on 10 february 2009.
The collision sent hundreds of pieces of debris flying at high speed across low-Earth orbit, threatening other satellites and increasing the risk to a NASA shuttle mission to fix the Hubble Space Telescope
dumping its GSAT-4 communications satellite into the Indian ocean. The failure is likely to push back the planned 2012-13 launch of India's unmanned Chandrayaan-2 lunar mission and further communications satellites.

Better imaging techniques using Landsat data at higher resolutions are available, he says, pointing to a recent study on loss of forest cover in Indonesia4.

He and other experts also say that an over-reliance on inadequate imaging by an Indian satellite system is making such destruction easy to overlook.

Landsat 7 data from 1999 through 2012 were obtained from a freely available archive at the United states Geological Survey's center for Earth Resources Observation
and Science (EROS). More than 650000 Landsat images were processed to derive the final characterization of forest extent and change.
The analysis was made possible through a collaboration with colleagues from Google earth Engine who implemented the models developed at UMD for characterizing the Landsat data sets.
Google earth Engine is a massively parallel technology for high-performance processing of geospatial data and houses a copy of the entire Landsat image catalog.
Brazil used Landsat data to document its deforestation trends then used this information in its policy formulation and implementation.
The team led by Carnegie's Greg Asner in close collaboration with officials from the Peruvian Ministry of Environment used the Carnegie Landsat Analysis System-lite (CLASLITE) to detect
NASAS Landsat directs restoration to at-risk areaswhile the 138000-acre Silver Fire still smoldered forest restoration specialists were on the job.
They analyzed maps created using Landsat satellite data to determine where the burn destroyed vegetation and exposed soil--and where to focus emergency restoration efforts.
And Landsat satellites built by NASA and operated by the U s. Geological Survey help direct the crews to those forest areas needing attention.
In Landsat images he looks at two of the 11 spectral bands--the near-infrared band and a short-wave infrared band.
and so sends back a strong signal to the Landsat detector that isn't present over burned areas explained Jeff Masek Landsat program scientist with NASA's Goddard Space Flight Center in Greenbelt Md.
But the shortwave infrared band--added to Landsat satellites starting with Landsat 4--has a distinct spectral signature for burned areas.
While he also employs remote sensing data from other satellites Landsat is the satellite of choice Albury said.
And with Landsat 8 online this summer the new images don't have the gaps present in Landsat 7 imagery.
He's counting on Landsat 8 being calibrated closely to Landsat 7 he said so he can compare a pre-fire Landsat 8 image with a post-fire Landsat 7 version or vice versa.
It's one of the reasons why the Landsat team focused on calibrating Landsat 8 so the reflectance data it gathers is measuring landcover
They identify those risky areas with a combination of the Landsat-derived maps reports from the field

By linking data from Landsat satellite images over a 20-year period with observations on the ground they found that 9. 1 to 16.9 percent of tree mortality was missing from more conventional plot-based analyses of forests.
#Landsat senses a disturbance in the foresta new way of studying and visualizing Earth science data from a NASA
Kennedy created the Landtrendr program specifically to work with data from the NASA and U s. Geological Survey (USGS) Landsat program.
Kennedy's new way of viewing Landsat imagery has changed already how the Forest Service in the Pacific Northwest operates its yearly forest monitoring program that uses ground stations satellite imagery
Kennedy says that Landtrendr works because of the unique nature of Landsat data. The data embedded in images are a scientific record of Earth's surface that goes back 40 years.
what people think of as crummier images says Curtis Woodcock a remote sensing specialist at Boston University who employs a similar method to Kennedy to build an image of the landscape out of Landsat data pixel by pixel.
