NASA shows Indochina and Central Africa covered in fires

NASA’s Suomi NPP satellite’s VIIRS instrument (Visible Infrared Imaging Radiometer Suite) collected natural-color images from Central Africa and Indochina, where farmers prepare their land for seasonal planting by deliberately setting fire. Fire is used to return nutrients to the soil and to clear the ground in these parts of the world. Although it helps enhance the crops, it produces smoke that plays a significant role in the seasonal air pollution, as it degrades the air quality.

The Indian Space Research Organisation (ISRO) will map 500 cities in September this year. Urban planners' work is to be supported by this information and nearly 50 million people are expected to benefit from the outcome.

Satellite images are going to be used by the National Remote Sensing Centre (NRSC) to illustrate several features of cities with an average of 100 thousand inhabitants each.

Easier access to Landsat data improves remote sensing research

Daily image acquisitions by Landsat satellites from 2000 to 2014, with a clear increase during last year. (Image: NASA)

The technological improvements of the past decade have brought into scene a faster and more efficient way of working with Landsat satellite data.

Scientists and students can now spend more time analysing and evaluating instead of compiling and sorting data from satellites. The modernization of the remote sensing research process has occurred thanks to two main factors: the growth of computing power and the public and free availability of Landsat archives from 2009.

DigitalGlobe: End of QuickBird mission

QuickBird's final image showing Port Elizabeth in South Africa

On 27 January, the QuickBird Earth Observation satellite re-entered Earth’s atmosphere after 13 years in orbit. It was a satellite of the imagery provider DigitalGlobe and the company's oldest satellite.

DigitalGlobe stated in a press release: "QuickBird made more than 70,000 trips around the planet, capturing some 636 million square kilometers of high-resolution earth imagery that contributed to humanity’s understanding of our changing planet."

Tracking Supertyphoon Neoguri from Space

Super typhoon Neoguri seen from space.

In early July 2014, Super Typhoon Neoguri has been heavily affecting Japan. Neoguri developed from tropical storm into a super typhoon over the first week of July. Astronauts onboard the International Space Station and NASA’s Earth Observing System satellites, Terra and Aqua, have tracked Neoguri since it was 238 miles west of Andersen Air Force Base on Guam.

DLR Radar Satellites trace Settlement Patterns

The vertical structures of building reflect the satellite radar signals

Scientists at the German Aerospace Center (DLR) recently developed a satellite-based map of human settlements, with a precision currently unparalleled by other global surveys. The maps are based on data of the German radar satellites TerraSAR-X and TanDEM-X captured from an altitude of 500 kilometres. The imagery has a resolution of three metres allowing to identify even individual buildings.

Predicting droughts with data from ESA's SMOS satellite

satellite images help to predict drought and crop yield

The European Space Agency’s Soil Moisture and Ocean Salinity (SMOS) mission was orginally designed to deliver information on water cycles. The satellite is now also being used to predict droughts and to monitor crop yield.

The Emirates Institution for Advanced Science and Technology (EIAST) of the United Arab Emirates announced that their DubaiSat-2 Earth Observation satellite is in orbit and fully operational.

The last phase of calibration started on 21 November of last year. The satellite verified and validated its electronic systems. The next phase included calibration of sensors and ensuring high quality of data seta.
