Earth observation cubesats to be developed by Planet Labs

Dove cubesats of Planet Lab's "Flock 1" constellation.

The American private company Planet Labs announced that it will invest USD 95 million into the development of Earth-observation satellites of reduced dimensions and high-resolution imagery potential. The cubesats will be just 20 centimeters long, 10 centimeters wide and 10 centimeters tall.

The so-called "Doves" will be able to capture imagery with a resolution of 3 to 5 meters and will deliver cost- and time-effective pictures of the Earth for a wide variety of purposes, such as scientific research and disaster management.

Ensar Gul, chairman of Turksat Satellite Communications, announced the production and launch of national satellites to occur within a five years time-frame.

“If you have experience, you can build a satellite within three years and launch it within another two years. That means Turkey will have its own satellite within five years,” Gul said.

Turkey has already sent three communication satellites in orbit and has built five satellites in total. Also, the country possesses an earth observation satellite and is currently developing its own space agency.

Successful Navigation Test Campaign for recovered Galileo satellite FOC-FM1

Galileo FOC

The European Space Agency (ESA) has recovered one of two satellites (Galileo-FOC FM1) that were put into the wrong orbit when launched on 22 August 2014.

The European Commission will take a decision shortly on whether to employ them for the Galileo satellite navigation system as originally planned.

The two satellites, the fifth and sixth of the Galileo series, were directed into a prolonged orbit - up to 25,900 km above the Earth and back down to 13,713 km - rather than completing the expected circular trajectory.

Philippines: LiDAR mapping of major river basins completed

The Philippines are frequently affected by floods

The Department of Science and Technology  of Philippines (DOST) has achieved the Light Ranging and Detection Technology (LiDAR) mapping of the three major river basins in Western Visayas.

As part of the Disaster Risk Assessment, Exposure and Mitigation (DREAM) project, the mapping will assess the risk of flooding in Jalaur River, Panay River and Ilog-Hilabangan River in Negros Island.

GRACE satellite shows groundwater loss in US

Map of the groundwater deficit based on GRACE data

In a new study by NASA and University of California, Irvine, several maps combining data from the satellites of NASA's Gravity Recovery and Climate Experiment (GRACE) with other satellite and ground-based measurements modeled the quantity of groundwater in the Colorado River Basin. The scientists found our that more than 75 percent of the water lost since 2004 in the drought-stricken Colorado River Basin has come from underground sources.
